I need a way to programaticaly block and then later unblock specific websites based on their domain names. I only need to block browsers (so http & https would be sufficient, I guess?) but not just Internet Explorer, it should also work for anyone trying to run Chrome or Firefox too.
View 4 RepliesSo I have been working on some code that is a supplement to a video game that I play (doesn't really give me an advantage, I'm against cheating) as recreational programming to get me to learn more things which apparently is working immensely.The video game is called DoTA which is a custom map in Warcraft 3.
What I am trying to do is to make a program that can manually click the skills when the user presses the key they bound to that skill. This allows for more precise skill usage as keybindings in the game change randomly which causes chaos.
I first tried using mouse_event to move, click down, click up, return back to original location. This worked, but I ran into a problem that occurred if mouse movement by the user was happening while the code was being ran. The problem mainly would cause the mouse to move off the skill before clicking or even after the mouse down event.
So then I looked into SendMessage and PostMessage but it took a while before I could fully grasp everything about the functions mostly due to many examples posted online being different from one another as far as the declarations.
I now have matched the output that happens according to Spy++ when I actually click the mouse myself with various PostMessage and SendMessages, but am still having an odd problem:
I provide the coordinates to click on say Button 1. Spy++ tells me it is clicking it properly, but I do not actually get a click. However, if I manually move my mouse over that button, even on the very corners of it, and then press the key, it clicks it (although it also seems to work on one other button in the game.) Other than that, it will not click any other button besides the one that the coordinates are over.The game does not have any child windows so it doesn't seem like I can get the handle of the actual buttons themselves.Here is what I have as test coding to figure this all out (the sleep time in between mdown and mup is because the game doesn't register if clicked too fast):
Option Explicit On
Imports System.Runtime.InteropServices 'MarshalAs, Marshal
'Imports System.Reflection 'assembly
[code]....
I was thinking that if there was a way to maybe pause control from being able to move the mouse that I could just revert back to the original mouse_event code as well, but I haven't found anything that can take away control like that (actually, I wouldn't even want that posted TBH as it could be used for malicious stuff).
EDIT:The code at the bottom is just stuff I was using to match what happens when I actually click according to Spy++.

I am wondering how I can select and pull specific bits of data from a block of information a user pastes into a textbox. For example, the information has fixed words and is always in the same format, but the numbers relating to the words may be different. One report might say, for example, Cars: 1.176 and another may say Cars: 863. How do I pull the information about the "cars" from a the block of text with the number value even though it can be different each time?
I must note that there are many many of these scattered throughout the average report and I need to pull the values of each of them in a single click, then paste those values into a different area on the form.
I have used VB6 years ago. Few days ago I just got started again with VB 2010. So I'm newbie again, Almost forgot everything. I want to create a program for parental control that block specific websites.
What I exactly want to do is The code should check the titles of the open windows and see if it is blocked one. If it is, it will close the browser with a message showing it's blocked. For example If I put "yahoo" to check and someone opens yahoo.com it should be terminated.What I have done so far is, I made DOS batch file that will terminate all the browsers that are open and set that ready to run when the title matches blocked site name/address.But I am stuck at how I can check the titles of the window that are open.

We have an item cull that retrieves items and their appropriate data from one server. Their Primary Keys need to be INNER JOINed with another table. However, the second table is on another server. We can retrieve that data using a separate select statement and accompanying VB objects.
How would one go about this programmatically in VB? Is a loop the best practice available? Although we are in a Microsoft Ecosystem, Server Linking is not possible.
I am programmatically updating some columns in a datagridview. When the user has also updated some columns then my program generated changes are also saved to the database (MSAccess). If the user does not update a dgv column, my program edits are not saved. I have read in another posting somewhere that I should be updating the bindingsource rather than the dgv cells. I have some code that was attempting to do this but it doesn�t work.
Dim dvr As Data.DataRowView
With TblClassMembersDataGridView
.EndEdit()
.CommitEdit(DataGridViewDataErrorContexts.Commit)
[code]....
PS. Is the bindingsource in a on-to-one relationship with the table returned by the Fill method? If not, I can see one obvious error.
I can edit the values in the dgv cells manually, add rows, delete rows all without problem and then update the database.My problem is in one form where I want to allow the user to filter the rows in the grid and then enter a value in a textbox and programmatically update all the cells in one column with that valueI can update the rows, and see the changes in the datagridview. When I try and update the database (using UpdateQuery on the underlying TableAdapter of the datagird) only some of thechanged rows are being updated I though it might be related

I wrote the code and it runs through it perfectly, the problem is that it will only save it to the database temporarily. So once I close down visual studio for the night and come back to it what's been entered is gone. It's not a published program still in debug mode but I've not run into this before. I have another program I'm working on that I'm running purely in debug mode and it works flawlessly. The code between the two is the same cause I just copied it and changed the parameters. Any ideas? I'm using an sql mdf btw.I should clarify, don't know if it matters or not, that the DB that is working is in SQL server whereas the DB I'm having trouble with is a mdf that I added into the program.
View 3 RepliesIhave created a system that allows an IT manager to log faults and assign them to available technicians, basically, you select a member of staff, a technician and describe the fault and then log it. But what I want to be able to do is take the technician out of the table until the fault is cleared and the technician is free. I have started this process but my head is spinning and I am not 100% where to turn next. I currently have a Busy field in the technician table and I have the code that allows the technician's busy status to change to 0 instead of 1 but I cannot for some reason get it to turn back to 1 when I clear the fault.
I think I may need some sort of If then statement like
If datagridview2.currentrow.cells(4) = 0
Then datagridview2.currentrow.remove
I've been using a FileSystemWatcher to detect changes and this is the code that changes the technicians busy status to 0:
Dim BusyM1 As String
BusyM1 = DataGridView2.CurrentRow.Cells(4).Value
sql = "update Technicians set busy=1 where busy='" & BusyM1 & "'"
Dim commandUpdate As New OdbcCommand(sql)
[Code] .....
And here is a code I tried to use to return the status back to 1 for the technician busy status
Dim NotBusy As String
NotBusy = DataGridView2.CurrentRow.Cells(4).Value
sql = "update Technicians set busy=0 where busy='" & NotBusy & "'"
Dim commandUpdate As New OdbcCommand(sql)

I have a graphics application I'm working on that displays full screen so there's no control in the upper right to close the application. I have it set up so that a right click closes the application but I noticed that a right click menu comes up on the desk top after my application closes which is no big deal. You could ignore it but I was wondering if there's a way to turn off the right click menu so that it wouldn't come up though I would want it to be enabled after that first click that closes my program.
So the right click would close the program disable the right click menu and then enable it again so that the next right click would show the menu. Haven't come up with anything on searches. I could use something else to close my application but if there's a convenient way of doing this I would like to find out what it is. I have almost every key on the keyboard doing something though I haven't used F1 through F12 at the top of the keyboard. Maybe I'll use F1 if I don't find out how to do this. How to use F1 to F12 to close or do something?
I've been using keypress events to do a lot in my application but for
Select Case e.KeyChar
Case "F1"c
isn't valid.
I tried other things. {F1} etc. I have option strict on. Thus the little c is necessary for characters like "a"c or "b"c.
I'd like to temporarily disable events for a given control. For example, the SelectionChanged event on a combobox might be used to update a display every time the user changes the combobox... but while I'm filling the combobox with values, I don't want the SelectionChanged event to be firing over and over... I need to disable events while the combobox is being populated. How do I do this?
View 12 RepliesMy VB program creates a file on a NAS drive via the SaveFileDialog component in a different user context than the person launching it.It works because the person who runs my ClickOnce deployed program uses RunAs from the program's exe (thereby bypassing the ClickOnce pre processor). The problem is that the program extensively supports drag and drop which doesn't work between the User and RunAs contexts.
The program is a VB 2008 Express Windows Forms Application running on XP workstations with peer-to-peer (workgroup) access control. i need to execute only the SaveFileDialog component with impersonation via the user account we've been using with RunAs. Something along the lines of what RunWithElevatedPrivileges accomplishes in SharePoint Services. This is not happening in a hostile security environment - so, the solution needn't be impregnable.
