Checking Treeview Nodes - If Parent Is Checked Check All Child Nodes
Aug 31, 2011I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

Detect An Unexpected Shutdown Within A Program And React To It In A VB Program?
Aug 14, 2009I'm working on a web browser named Hyvar.NET and i'd like to integrate a form of shutdown detection into it.
Currently, it simply uses a tri-option setting to decide how it opens - like this
If My.Settings.LoadLastOnStart = True Then
frm.wbTab.Navigate(My.Settings.LastOpenedPage.ToString)
ElseIf My.Settings.HomeOnStart = True Then
[Code]....
Each variable is appropriately named for its job as you can see.
However, i want to change this to react to correct and incorrect shutdowns - unexpected and user instigated ones for example. I.E: if the settings variable for the detection contained 0x000000, it could indicate a clean exit and continue as normal with a new session, but 0x000001 would indicate an unclean shutdown and present the user with an option of reopening the last session or continueing as normal, like in IE 7/8
Im 100% sure this will require a windows API call
Tree View Nodes Children Added While The Program Is Running?
Feb 25, 2012I have been developing all sorts of programs and have found myself making a password safe program. While making this program I tried to use a listbox to display the passwords and such but have found that to be insecure and hard to manage and so I decided that adding a treeview to replace the listbox would probably be my best option. So in my program the user has an 'Add Entry' option and that loads a form where they enter the information they want put into the program and saved. So far I have it set up like this, They enter the user name in textbox 1, their password in textbox 2 and the website this information goes to in textbox 3. And then I have an 'Add Entry' button and when they press the button it adds the website to a node, and I'm trying to make the username a child of that node, How should I do this because I've been messing with this for about an hour and can't seem to figure anything out. Here is the code for the 'Add Entry' button if it helps:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form3.TreeView1.Nodes.Add(TextBox3.Text)
Me.Close()
End Sub
Loop Through Treeview Nodes To Delete Certain Nodes?
Dec 16, 2010I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

View 1 RepliesDetect Whether A Program Is Open?
Jan 6, 2011Objective : Time how long a user has been on the internet. I have never delved this deep into Visual Studio. I am suing Visual Basic 2010 Express. Please move it if you need to.
I want to have a program - that will detect running processes. If Internet Explorere EXE or Chrome or FireFox exe or any other browser is installed - as soon as that process starts the timer will appear.
When those processes are closed by the user the timer stops counting. This is possible but i dont know how. But i only want it to time just one internet process because timing them all when they are openend up at different times could cause bugs. Unless on the time form you have 1 timer for IE, 1 for FFox, 1 for Chrome 1 for Opera..

Background Program To Detect When Regedit Tries To Run?
Sep 3, 2011I have Windows XP Pro, SP3 on a Dell Dimension 9150 with VB 3.0 and all other Visual Studios up to and including VS2010 Pro.I'm not exactly an expert VB programmer, but I have written several different programs.I would like to write a VB program to run in the background and detect when the program regedit.exe/regedt32.exe tries to run.Once the regedit program tries to run, I would like my background program to pop up a message with three options. Allow, Do Not Allow and Cancel.
The Allow button would allow regedit to run.The Don't Allow button will not allow regedit to run and continue to run in the background. The Cancel button would not allow regedit to run and would cancel the background program.Can this be done?I would explain why I want to do this, but it would take too much of this thread. However, if anybody really needs to know, I will accommodate their request.

View 5 RepliesDetect Which Executable Started Your Program?
Jun 13, 2009I have a custom button in IE8 which starts up my program. Now what I wanted to do, was pass an arguement such as: 'myprogram.exe /ie'
From the IE8 button, and well my program will do rest from there. Now my program adds the button just fine, shows up fine, all that works. But each time i'd add an argument after my application path, IE8 would say it can't find the program. If you want to test this out, goto run, type in gpedit.msc, then 'User Configuration'->'Windows Settings'->'Internet Explorer Maintenance'->'Browser User Interface', and double click on 'Browser Toolbar Customizations'. And in the small window that pops up, is an option for adding custom buttons to IE. I was using this for testing purposes, since it was faster to edit a button here than in my program. When you add a button you choose the executable to link it to. But if you add any arguments after it, IE will simply not be able to find the program. Even if that same command works when you type it from 'run'.
So, now my question is, since apperntly you can't have any arguments in the button, is it possible to detect what executable starts your program? For instance, detect if iexplore.exe started up my program?

Nov 30, 2011Is there a way to detect a Chinese character in a string which is build like this:

Write A Program To Automatically Detect And Identify A Particular Device?
Sep 24, 2009I am trying to write a VB program to automatically detect and identify a particular device that will only communicate to my program when I have 2 or more devices plug into the USB port. One way of doing it that I can think of is to scan through the available port and do a write and read to identified the port. But that would take up a lot of time if I were to scan through say 5 available port.
