I have a vb.net 2008 application which has its corresponding icon.
The icon shows correctly except in the taskbar when the "small icon" setting is on.
My vb.net project includes a .ico file which when I see in the IDE includes 16x16, 32x32, 48x48, 64x64 and 256x256 bitmaps, in 4, 24 and 32 bits, also 3 .png images in 256x256 32 bits each.
I made the icon myself simply using a 64x64 bitmap and then converting it to .ico, and assigning it to the application in the project properties. I thought windows would use and escalate the corresponding image, it shows even in the file explorer properly in the small icon form, but not in the taskbar.
I have a TreeView.I am building the nodes within a For/Each loop.I then add icons to each node from an ImageList control.The icons load properly. However I am noticing that when I click onto the nodes, after the TreeView is built, the selected node defaults to another image. It seems to always default to the image which has the index of whatever is set in the Properties Windows for the Control for ImageIndex.So assume that the ImageIndex is set to 0 in the Properties Window.If I add ImageIndex 1 to the node at run time (See Below), ImageIndex 1 show up but once I click onto this node the icons switches to ImageIndex 0.[code]

I tried a few different way but just can't see to get it. Seems if I set the parent icon to what I want, selected and unselected, it also changes the children. What I am after is to have a parent icon that does not change regardless if it is selected or unselected. But the children will follow the icons for selected and unselected. If I don't add a third icon it all works fine, so how do I add one to parent but not change the children?

View 4 RepliesI'm trying to do treeview checkbox function in Visual Studio 2005 using VB.Net. I have successfully loaded the treeview checkbox as you can see in my attachment. But the problem starts here. I have designed the form before I inserted any code inside of it so my programming is mainly trying to connect to the instance in the design.
This are the following function I want to perform on the treeview checkbox:
1. When I select the ITAD checkbox, all the nodes under it will be checked automatically
2. When I select the Raw checkbox, all node under it will be selected.
I had a treeview that had checkbox and its content is like file explorer. the checkbox is check when users want to delete that files or directory, after the selection, press the command button then all selection will be process (on this case deletion) how that to be code?

Im making an application that needs to use an explorer-like interface to let users select directories from their hard drive, so I've got a TreeView that I load all of the folders into and I have the checkboxes on each node enabled. The problem is that there are only two states for the checkboxes so if someone selects a folder, then minimises that node then they no longer have any way of knowing that sub folders are still selected.[code...

I have a treeview, it lists all folders and subfolders and files within each folder. Now, I want to display each file / folders associated icon. I am using the SHGetFileInfo API, it works sort of, what I mean by sort of is, that my treeview doesn't update after each folder / file. Sometimes it keeps giving me the Recycle Bin's icon at different folders.

I have a WPF window with a TreeView that contains a checkbox at each node. I want to be able to capture the state of the checkboxes but I don't know how. (I am trying to do this without writing much of the code in XML)
Here is what I have in the XML:
<TreeView Grid.Column="1" Grid.ColumnSpan="3" Grid.Row="1" Height="200" HorizontalAlignment="Left" Margin="126,299,0,0" Name="TreeView1" VerticalAlignment="Top" Width="220" ItemsSource="{Binding}" DataContext="{Binding}">

I'm trying to get each checked checkbox inside the treeview. I was thinking of looping inside the checked items, but the code just get stuck on first checked textbox and displays it over and over again.
Here is the code,
Dim Box As ListViewItem
For Each Box In ListView1.CheckedItems
MessageBox.Show(Box.Text)
Next
I have found several examples of how to set text of a textbox across threads, but no examples of how to set other properties like the checked on a checkbox. What i am doing is listening on a serial port for data received.When the port receives the data I want to check a character in the string to see if it is a 1 ot 0 and set the checkbox to the proper state.I cannot figure out how to do that across threads.

I have a treeview containg a hierarchy of fire stations with child nodes being the trucks in the stations. I drag and drop trucks into listboxes that represent incidents. All this has a SQL Server DB behind it. As the trucks are logged into the incident a SQL notification returns the update and I use recursive call code through the nodes to set the backcolor of the truck node to red, (not available). When the truck is released from the incident the same process sets the backcolor back to empty,(now available). The code works just fine until. If you exit the screen and then return back to the screen suddenly the setting of the backcolor no longer works. The code runs as I have stepped through it and the line setting the backcolor is processed but the display in the treeview does not change.I have tried, after finding the node making it the selected node and using the afterselect event to change the color. That worked until exiting and reentering the screen I found that the afterselect event did not fire after setting the selected node.When you enter the form with the tree view the tree view is rebuilt each time taking data from the database and presetting the backcolor for any trucks already involved in an incident.If you completely exit the application and start up again there is no problem with backcolor settings, the problem is only if you stay in the application and exit and reenter the form with the treeview.I am using VS2008 and I have tried the application on Windows SBS 2003 R2, Vista Premium and XP Professional all with the same result.
View 3 RepliesI have a icon for my application that I set in the project properties window there is a little drop down box to browse to the icon location. While debugging everything is good. Once I build the app and place it on a PC and manually start the app all is good. My app starts with windows and now every time the program goes to start I get an error that the icon cannot be found in the DocumentandSettingUSERNAME folder. So the question is do I have to place my app icon in this folder? In design I have the icon in the binDebug folder and that is were I point to in the Project properties page.
I am using VS 2008 VB.net.

View 1 RepliesI have a checkbox on my form chkActive, I want to deal with it in 3 cases. [Code] I don't have a problem with building the query, my problem is with clicking on the checkbox by clicking on the checkbox by mouse, I can only get Checked and Unchecked, I tried to use the right mouse button click, it did not fired (or I did not test deep enough) I know I can put a button to change the checkbox value to Indeterminate but that will be ugly. I can replace checkbox with combo, which is what i am thinking of doing but I just wonder: Cannot I set the checkbox state to Indeterminate by mouse any how?

View 2 RepliesI have a custom cursor that I have as a ico file as cur files are only mono coloured and 32x32.
The only problem in using a ico file is that I can't set where the hot spot is and at the moment it is set in the middle of the icon which is no help
I was looking on the msdn website and it said to set the hotspot like this
Dim instance As Cursor
Dim value As Point
value = instance.HotSpot But I don't know how to set the point value to (0,54) which is where I want the hotspot to be located.
I currently have the following code but I would like to get away from going to a physical location. If I have the icon as a resource, how can I programatically add the icon? I don't want to use the form's designer to do this.
Sub Form1_Load()
Dim ico As New System.Drawing.Icon("C:Resourcesicon.ico")
Me.Icon = ico
End Sub
