I was woundering if there is anyway via VB.net to have only two option on vista's shutdown menu. I only need "Logoff" and "Hibernate". just woundering if there was anyway possible to have these two options.
View 5 RepliesI am in need of a form that shows various options, exactly like the Options in Visual Studio. Since there are so many options I too want them categorized, with a TreeView to the left taking care of showing the right category.The usual 'easy' approach here would be to just place a TreeView control on the form, add some nodes, and give those nodes a tag or key that corresponds to a panel or UserControl with the options for that category.Since there will be a lot of options however, this is not really feasible design-wise; the form would be cluttered with possibly 50 panels, all of which I would need to select and bring to front from time to time to add controls to them that represent the options.
So I decided to create a custom control that does exactly that. The control is very similar to my Wizard usercontrol, users can add OptionsPanels at design time, which inherit Panel and simply represent one panel of options. When they do, the panel is added to a container panel, and at the same time a TreeNode is added to a TreeView. The control uses a custom ControlDesigner to handle design-time clicks in the Treeview, selecting a different node would select and bring to front the corresponding panel, allowing the user to add the controls he wants.
Due to the design time support the problem of having 50 panels is no longer present, only one panel will be visible at a time and selecting the right panel is as simple as selecting the corresponding TreeNode, just as during run-time. Anyway, I got all this working, but only for a single 'level' of categories. As you can see in the Visual Studio options, there can be multiple levels of categories. For example, the Environment node has a bunch of children, where each child represents one 'options panel'. There can even be deeper nesting, see the Text Editor node for example.Let me begin by drawing out the basics of how my control works so far.
The main control is an OptionsView control, which contains a SplitContainer with a TreeView to the left and a OptionsPanelContainer to the right. The OptionsPanelContainer is merely a Panel to which only OptionsPanel controls can be added, and which raises events when this happens, as well as when OptionsPanels are removed from it. An OptionsPanel also inherits Panel, and these are the actual panels the users will see in the control, one for each option category.For now, each OptionsPanel has exactly one corresponding TreeNode (and vice versa). In the Visual Studio options, each 'parent' category usually has a 'General' node as the first child, and the parent and this General node show the same option panel, but I am ignoring that for the moment.
The OptionsView control has a property Panels that returns the ControlCollection (Controls property) of the OptionsPanelContainer (in other words: it returns a collection of OptionsPanels that are in this container panel).
vb.net
<Editor(GetType(Designers.OptionsPanelCollectionEditor), GetType(UITypeEditor))> _ <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)> _ Public ReadOnly Property Panels As Control.ControlCollection Get Return Me.PanelContainer.Controls End Get End Property
A custom CollectionEditor for this property takes care of the designer: even though the property type is ControlCollection, the CollectionEditor knows it should create instances of the OptionsPanel control instead of just Controls.When it does this, a corresponding TreeNode is also created and its Tag property is set to the OptionsPanel. Vice versa, the Node property of the OptionsPanel is set to the node. Hence the node and panel both know their corresponding object.
vb.net
Public Class OptionsPanelCollectionEditor Inherits System.ComponentModel.Design.CollectionEditor Public Sub New(type As Type) MyBase.New(type) End Sub Protected Overrides Function CreateCollectionItemType() As System.Type
[code]....
So far so good, this all works fine. I can add Panels via the designer and when I do a new TreeNode appears in the TreeView. I can select this node and the panel becomes visible (comes to the front).Now, I am a little stuck. How do I implement child option panels? And more importantly: how do I let the user add child panels?The most logical choice I think is to let each OptionsPanel have a property (ChildPanels or something) that returns the child OptionsPanels for that panel. Once the user selects an OptionsPanel then, he can look in the property grid to find its ChildPanels property and add child panels to that.
There is a problem though: what would this property return? It must return a ControlCollection of some container (this is, I think, a requirement for the designer features to work, otherwise panels are not added to the Form.Designer.vb file). But there is no container. I cannot add them to the OptionsPanel itself, that would make no sense because the parent OptionsPanel has its own set of controls (the options itself...), there cannot be another (fully docked) Panel on top of those obviously.The container of the main OptionsView then? That is not an option either, its Controls collection holds ALL OptionsPanels, not just the children of the selected panel. I cannot 'select' only the right panels either, that would require me to return a new instance of ControlCollection, it would be impossible to return the actual ControlsCollection that holds merely a small selection of its controls.
Is there any way to turn off a remote pc that's not by using shutdown /s /m \computer name etc...I just want to turn off the server computer at night from my laptop. Is it possible to make the program check for pings and then shutdown? Or is there an easier way? (Maybe if I'm not on the local network send over a "signal"(?) to the pc so that it'll shut down..?)
View 6 RepliesI'm trying to create a way for the User of my application to Log Off, Shutdown, or Restart the PC.
The idea is that User can more quickly access these options from my application and if they choose, force these actions instead of waiting for the OS to respond.
Here's how I'm trying to do it:
CODE:
Log Off works just fine. It's shutdown and restart that doesn't work. From the research that I've done, the Consts seem fine and the function obviously works correctly because Log Off works. I am running the application as an administrator, so that should affect it.
I have an application that starts from Sub Main and I need to run a sub when the system is about to shut down, restart or logoff so it can save it's settings. I found some code on google:
Imports Microsoft.Win32
Public Sub Main
AddHandler SystemEvents.SessionEnding, AddressOf OnShuttingdown
[Code]....
But it doesn't seem to work, Windows shuts down yes but when I re-start the vm and run the app it opens with the old settings, not the ones that I changed before I shut down the vm. Anyone know of a way to do this or to fix the code above, I don't think my OnShuttingdown event is being handled.
With the following piece of code
CODE:
The Or keyword is confusing me. So in the above example which variable gets set. Does options = options or does it set RegexOptions.none.
I have this program I'm writing that needs to print for instance what date it is a 100 days from now or 30 days from now. Is there a function in VB.NET that lets me do something like this?
View 2 Replies1. i have a panel on a windows form with picture boxes in.I wish to click on one and open a specific directory on my pc , much like clicking on one in explorer.
2. is it possible to run executables with options? i.e wmplayer.exe" /prefetch:1 if i use shell it throws an error obviously.
3. is it possible to open windowsa control panel items from within my program,like network and sharing. I am using win7 and VB2008
i have various options in my app, some complex some not, these 2 save on application exit and reload on application start themes, and layouts. There selected via a comobox each.So onto the question, how does everyone create options menus? With out using a menustrip/toolstrip?
The method i was using , was to have a picture box show a panel when it was clicked on, the panel had all the various options etc on it. This idea worked great, but meant working in design mode was a pain because the panel and everything on it had to be moved round to see the items under it on the form.
So today i decided to see what other ways i can implement a menu, and i changed it so the picturebox/button now opens a dialog, and all the options etc are on that dialog, this works great except options such as the combobox 1 and combobox2 last used setting (text data binding) doesn't load when the application is started, they only load when you go into the options. Which defeats the point, if a users going into the options just to load the settings its useless them been saved.
The time to initialize the dialog (for it to appear and be click able) is 5 - 15 seconds, not alot i know but the 1st method of using a panel it initializes instantly, but then its never really closed just made hidden, so i uses more system resources.So how does every one else implement there options menu?
im new to programing infact this is my second day... im unsure of where to ask this question and i know this is probably not the hardest thing to do lol, i am making a "launcher" to launch a few games, a webbrowser and a few other things, however to do this i have a "set path" in the code, i want to know if anyone can help me make a "setup page" so the user of the launcher can set the path [eg]- to launch firefox i have If IO.File.Exists("C:Program FilesMozilla Firefoxfirefox.exe") Then Process.Start("C:Program FilesMozilla Firefoxfirefox.exe")not everyone has firefox installed to that exact location , so i need to make a settings page to set the paths, each file is launched buy a single button, in the future i may even make another program much the same for people who dont know how to use a pc nd just want to check emails and browse to a webpage.
View 12 RepliesAs i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
We have become disenfranchised with our med records scanning package and are doing in house development to create our own. With most of the interface built out, the monster of calling the Fujitsu Twain driver and pre-setting scan options is what I am looking for. Fujitsu does not have an SDK available on their web for this.

I set up some application settings for checkboxes on an app and then decided to remove them. When I set the Application Settings to (none) in the designer and restarted the app, the checkbox constantly checks and unchecks itself. I completely remade the app and removed the file that is used to store my.settings in the Local folder of the user's appdata profile. I also made sure to uncheck the "save my.settings" on shutdown.

View 3 RepliesI've written a program which I propose to give a local club, which sadly may be'attractive' to pirates so I propose to build in some sort of anti-copying feature.My idea is to hide a file in a folder somewhere in the club's laptop, then on program start up I'll check to see if that file exists and if it's not there, which it's unlikely to be on a pirates machine, I'll flag up a message box saying that if they have a legitimate reason to install the program on a different machine they'll have to contact myself.By way of nuisance value, pressing the 'OK' button on the message box will cause the machine running, what I'm assuming is a pirated copy, to shut down.I've been looking at the VB.NET forum and MSDN for ideas as to how to achieve this and the general opinion seems to be:

I have a fully working application which runs in the background while a user is logged in. What I need the application to do, is disconnect itself from the database, save the users settings and close itself when the user shuts the computer down or logs off.I know how to do those things, the issue I am facing is figuring out how to detect when the computer is logging off or shutting down. I thought about using log off scripts to do this but then it would be impossible to call classes and methods from my application as the log off scripts are not associated with my application at all. Are there any other methods of telling my application when the computer is shutting down and then run some lines of code?
