VS 2010 Administrator Priviliges On Specific Events?
Apr 19, 2011
I know I can set the program to require administrator privileges in the manifest file.However, I don't need the whole program to have these privileges.
I only need admin when I want to write to the registry (this doesn't happen often).9 out of 10 times when the program runs it doesn't need to write to the registry, so only when I click on a specific button the box where the user can choose wether or not to grant admin to the program should show.
i made one form database app and make it full trust app then i run it on non administrator user and when i try to save data it gives me exception but works very well on administrator user !!can i make the app works well on non administrator user?
i currently have a project that needs to edit a few files in the startuppath folder. on a non administrator o.s., if my app. is installed in ( c:program filesmy crappy little app ), i cannot write to those files. in win7, it does not even ask for administrator approval, just the option to save to my documents.. this can be quite a hassle to work with, specially on closing the app, since i have quite a few files that need to be updated.
I have this problem where is wont let me create and files through the command prompt via echo xxx> C:xxx in Visual Basic. If I do it sepoaratly and run the command prompt as admin (This is not using vb at all) then it will work. I have tried putting my vb app to require previlidges at both levels at different times, not at once, and I still got the same thing.So is there a way I can use the comman prompt through vb, but also making the command prompt being an admin without turning off UAC?The code that will not work is this.
does anyone know if its possible to find a control that would allow adding events to a specific date or displaying the events for specific day as a schedule?
I have been looking for options but I cant find any which either do what I want or that are free.
I need to write an app that will stop and restart a service on a domain controller. The app needs to be usable by all domain users without making them run as.
Therefore, I want to have the administrators login details within the app itself (I will encrypt them).
How do I get my app to run something on the server as administrator though?
My VB.net framework 4 windows program work fine for the users on Windows XP machines if they are in the local Administrator Group. I would like to setup this click once application to run as an administrator so the user doesn't need to be in the Administrator group. The program is reading the"C:Documents and Settings" & User & "Local SettingsTemp" folder looking for files with extension like "emf", "tmp" and "htm" and then deleting the files if they are older than 24 hours. We have a third party application that adds these file and doesn't delete them so I need the users to run this cleanup program.
I looked everywhere for this but not sure if it can be done. Is there a way to fire events when a user clicks a specific tab. Here is the image to show it better:I am trying to have the program execute a special function when the user clicks on customer info.
I have successfully converted the FullCalendar into asp.net / VB and it works perfectly. I am struggling to change the background colour of an event based on a SQL query. I have tried many of the links on StackOverflow and on the Full Calendar Docs [URL] but I have barely any knowledge of jQuery/Javascript so this is proving very difficult for me.I have 5 Employees and I would like each of them to have a unique colour on the Calendar. In my SQL table there is a SalesPersonID field for each employee. I want to change the colour based on the ID. e.g.: (I know this will not work in this scenario, it is purely for info)
If "SalesPersonID" = "1" Then cevent.className = "Steve" ElseIf "SalesPersonID" = "2" Then
create admin form to register, Remove, Edit user accounts in the system connected to Microsoft SQL Server R2 2008 or access database ? any toturial videos or instructuions step by step ?
Well I currently just finished my game, but it ended up around 1GB. Thus, I tried to revise the code to make it smaller. I am trying to get 2 form events under a single sub. For example, a sub for a town would have the shown event and the click event. However, when I try that it won't work.
The other way is to transfer variables and its data from one sub to another. But I dont know how to either Example:
Private Sub Number Dim TheNumber as integer TheNumber = 1
I made a custom control for my form. It's basically a custom button I made using a label.The only problem is, when I apply a myButton_Click event to the control in my main form, it will only be triggered if the control itself is clicked. The label takes up the entire form (it's docked inside it). The click event isn't triggered when the control (virtually the label) is clicked. You must click behind the label (the form's background) for the event to be triggered. How can I pass the myButton_Click event to the label so it is triggered when the label is clicked? I hope I'm making sense.
I took a VB class a couple semesters ago and I did really well. Unfortunately, it seems as though we only covered the very basics within the class, as I feel rather clueless right now.
Here's my issue. I'm trying to write a program that will encode notes (like music notes, A-G#) which are entered by the user, into digits, 0-9. Now I have the system laid out, in that 1-8 will represent A-A, while a 0 or 9 preceding a digit will represent a flat or sharp respectively.
Now my question is actually rather basic, but I just can't seem to figure out how to do this. The user will enter the note sequence by clicking on buttons (12 of them). What I'd like to do is create one sub that will handle all possible button clicks. I suppose it's possible that I could have separate subs for each and every button; but it just seems more efficient and cleaner to have one sub that manages them all.
The part I have completed and working properly will display a message (the same message) in a messagebox each time any of the buttons are clicked. So I have the "Handles" part working for all 12 buttons. But what I'd like to do is write code, perhaps "If" statements such that If "btnA" is clicked, then say "You clicked Button A," and If "btnASharp" is clicked, then "You clicked Button A Sharp," and so on. Is it possible to do this somehow by recognizing which event was actually triggered?
I am trying to make a UserControl or Component which can be dragged from the Toolbox onto a container control such as a Form or a Panel. Its purpose is to change the behaviour of that container. In particular, I would like to add functions to the container's painting and mouse actions. I DO NOT want to have to write code for the container itself -- that's the whole point of the Toolbox object.
I can do this by getting a reference to the object's Parent (or Host in the case of a Component) and handling its events, as this example illustrates:
[Code]...
However, I have heard that handling the events of a parent control conflicts with OOP principles. So I would like to know, does that objection apply in a case like my example? If so, what are the drawbacks? And what alternative techniques are available?
I'm working on a grid of cells that is something like a DataGridView, but not really. The two are close enough that you can picture a DGV for the purpose of this question. What is actually there (and this is true for actual DGVs) is a set of cells drawn on the screen with a couple scrollbars for vertical and horizontal scrolling which are only drawn if there is too much data to show in the visible cells. There aren't more cells than the ones that are visible, so when you scroll the scroll bar, it looks like new cells are being displayed, but what is actually happening is that the existing cells are just being filled with different data depending on the position of the scrollbar. The key observation is that the set of controls displayed in the grid is always the same (unless the grid is re-sized, but that's not relevant to this issue). The appearance of those controls can change, but the controls themselves do not.
One of the features I am adding is the ability to drag-copy data similar to how Excel works. In my case, if you click on a cell, then drag outward (move the mouse while holding the button down), all the cells in the selection rectangle are tinted green. This works nicely. Some of the cells are enabled, while others are disabled. If the drag selection includes disabled cells, those are not tinted. Only enabled cells can be selected, though a drag can cover disabled cells. The relevant point here is that some cells are enabled and some are disabled.
The feature that I am adding is the ability to do drag selection beyond the visible edge of the grid. The grid is a monthly calendar, and I simply can't get 31 cells onto even a wide-format screen. What I am trying to do is allow the user to do drag-copy onto days that are not currently visible. The way I do this, the user clicks in a cell, then drags out to the border, at which point the grid scrolls (the scrollbars move, and the contents of the cells is updated as a result of the changes to the scrollbar value). This is largely working.
The way I handle the selection is that when the user presses the mouse button while over a cell, a flag is set to indicate that the button was pressed, and the current cell is recorded (so that I know where I started from). MouseMove events are used to figure out what new cells the user has visited, and set the selection area based on whatever is under the rectangle described by the initial click point and the current point. Lastly, when the user releases the mouse button, the MouseUp event initiates the actual copy. At that event, I know that the user is done with that copy action. Therefore, the MouseUp event is kind of critical, and therein lies the problem.
As I mentioned, some of the cells are disabled and some are enabled. Disabled controls don't raise events. If I click on a cell, it HAS to be enabled, but that's fine. The problem is that if I then move the mouse in such a fashion that the grid scrolls such that the cell that I had initially clicked on is no longer enabled, then the cell doesn't raise events any more, and the MouseMove and MouseUp events stop happening.I only see one viable solution, which is to not toggle the enabled state of the grid cells. Instead, I would have to have to add a custom property that would make the control act and look disabled as far as the user was concerned, but it wouldn't be disabled as far as the program was concerned such that it would keep raising mouse events. This would be pretty rough, since I would need to prevent the control from appearing to have focus even though it technically would have focus
How can I use mouse events to move and click my mouse in another window.
For instance, I would like to move the mouse to 62,88 of "Untitled - Notepad".
so far I have:
Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hWnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As IntPtr) As IntPtr
I'm trying to make a way to navigate around a custom grid. Basically, I'm implementing the drag-copy feature from Excel. Right now, you click on a cell grid and can drag around the grid. Anything in the drag area gets a green tint. Once you release the mouse button, whatever was in the first cell selected is copied to all the others that are tinted. That works pretty nicely, but it works only for the cells visible on the screen. I can live with that, but decided that if you dragged over the scroll bars or the column or row headers,then the grid should scroll (if there is anywhere to scroll).
That's where the problem arose. It turns out that scrollbars don't raise the MouseMove event (at least not as far as I can see), and the MouseEnter and MouseHover events are not fired as long as the mouse button is held. Interestingly, the MouseLeave event does occur when the mouse button is held, just as the MouseMove event is occuring for all the cells. That's pretty annoying. Why do some mouse events get raised when the mouse button is down while the others don't? Also, I suppose, is there any way around this?
I am working with a picturebox and i am drawing lines during my paint event. My goal is too draw the lines and export the picturebox.image with the lines i drew out to a Everything seems to be working correctly so far. The code executes. A file is written. But it is always just the original image from the picturebox with no lines on it. I have setup the pictureboxes so i can see exactly where i am in the code when it trys to save. I can also verify that before i click the button that calls the save feature the lines are absolutely drawn in the picturebox.
I seem to remember someone telling me at some point that the lines i draw wih the paint event are not actually a part of the picturebox image but more an overlay on top of it. I think this may be my issue. Hopefully someone can shed some light on this.
A form's key events will fire when you press a key. Place a control on that form and it won't happen any more because that control has focus. There are exceptions to this however as you will see if you place just a h or v scrollbar on the form. The key event will fire because the scrollbars can't receive focus as is demonstrated by the following
Private Sub ScrollBar1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles VScrollBar1.GotFocus Debug.Print("Scroll GF") End Sub
[code]....
So I've made my own special scrollbar usercontrol and i can't figure out how to have it leave the key events alone. I'm pretty sure that the problem is that my usercontrol can receive focus at the moment.
I found that the way of doing this is "SetStyle(Windows.Forms.ControlStyles.Selectable, False)". I put that in the new event of my usercontrol and now it looks like this:
Public Sub New() ' This call is required by the designer. InitializeComponent()
I'm trying to use the events Validating and Validated on a ToolStripTextbox.
Private Sub txtMenuOwnIP_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtMenuOwnIP.Validated MyIP = txtMenuOwnIP.Text StatusLabelIP.Text = MyIP End Sub
[code].....
Neither code is firing.The CausesValidatition of the txtMenuOwnIP is set to true.I can enter stuff into that Textbox and leave it using the Mouse or simply piush Enter, but the posted code won't get fired (used a Breakpoint in both subs). There are no other event routines for this command used.
I'm trying to use a asynchronous UDP-Port to recieve data on a form.I manage to receive one message at a time(for each click of btnReadData), however if I do this receive in a loop (in order to continously receive new messages), my form seems to be locked.What am I doing wrong?
Public Class FPR2DIS Delegate Sub dDataReceived(ByVal Data As String) Dim UDPWorker As New Worker
I have a question for the well versed among you. I have done some research, but didn't seem to find the exact answer I was looking for. So without further adieu.Given an event which needs to occur at a very specific time, whats the best and most predictable way or making that happen.
A: Use a worker thread, and threading.thread.sleep(TIME).
or B: Use System.Timers.Timer or System.Threading.Timer to execute in (TIME).
NOTE- I am fully aware that any of these will work. My question is in regards to priority of execution. How will a timer, which I can't figure out how to set a priority on, compare to a thread with a priority of Highest or even Real Time. Microseconds DO count in this instance.
The problem I'm having is with the .close() event. Basically I've created the below code to prompt the user when closing the form they are currently viewing.
Private Sub Form_closed(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.FormClosing If MessageBox.Show("Do you wish to exit?", "Program Name", MessageBoxButtons.YesNo) =
I have a contextmenustrip containing a datetimepicker. Now the problem is that when I choose another date in the datetimepicker the event for that goes through without a problem BUT the event causes the contextmenustrip to go away. The problem is the contextmenustrip must stay shown. I solved the issue with contextmenustrip.show on the end of the event, this works but this has one big disadvantage. I loose all information about the sourcecontrol of the contextmenustrip, and this can't happen.A monthcalendar lets the contextmenustrip stay after his event, but a monthcalendar is too big what cause my menu to be clumsy.
I have an application similar to calculator, with button from 0 to 9, Enter and Clear. I made it possible to use the buttons by clicking on them and also by using numpad, like shown below: Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Let's say I cut a tab control with buttons on it and paste it into a Panel control. After doing this, all my control events are being unlinked from the event code. I have to manually relink all the events in the Properties window. Is there any way round this?
I have been trying to implement the jQuery weekcalendar using .net. What I can't seem to figure out is why weekcalendar states events.events is undefined after I make an ajax call to a webmethod I created which returns JSON. Below is the relevant code:
the question is really what is the correct convention (style) for raising and handling events. When a button is clicked it is generally handled by this method. [Code]
I have recently been trying to follow this convention by creating my own EventArgs class and inheriting the system.eventargs, Then adding my own properties. The problem is as my projects get bigger/complex I seem to be writing multiple eventarg classes. I then decide to try and create a generic eventarg class but this then seemed pointless thinking it would be easier just to pass the object directly instead of wrapping it up in "someEventArg" i have created.
