have a treeview with 13 different categories. Under each category are many sub-categories.At the minute the icons used to represent the categories are the plus/minus signs.I would like to use an Imagelist to change the icons to a closed folder icon when closed and an open folder icon when opened.
I'm trying to accomplish something similar to:[URL]...However, I find the author's approach to be a bit cumbersome and "hackish" when I know this may be doable from within the application or at runtime.
I am populating a TreeView with a list of cameras. Depending on certain properties of the cameras, I'd like to add certain images to that camera's node.The obvious limitation is a single image per node by default.
I am trying to setup a treeview control to display all drives and folders on the PC. So far I can display all drives and folders but the images will not show except rarely. I am using an imagelist with 4 images (index 0-3). The code below is used to load the drives in the treeview control. I have tried using every type of image possible from bmp to png and nothing. I have tried the Appllication.EnableVisualStyles() which I now know isn't needed in vs 2008. I am also having problems with a picturebox in another form that shows nothing but a shadow of the image. I suspect this may be a setting somewhere maybe in vs 2008 but am not able to find one.
Treeview Dim drive As Integer = 0, dir As Integer = 0 For drive = 0 To oDrives.Length - 1
I'm in need of a custom control that will allow me to do something like the attached image. It's basically a TreeView with the exception of having a row of PictureBoxes for each child node. I'd be happy with a ListView that could do this even. I tried it briefly with a DataGridView with ImageColumns but the "look" wasn't quite what I was after. I'd like the "Parent Node" text to be situated above the row of images and just can't seem to find a control that will allow this.
I am trying to insert spaces between Images and check boxes on a treeview node, in a windows form app i.e. checkbox (spaces) image (spaces) node text rather than default format checkbox Image node text
I have a treeview and text box below it... is it easy or even possible to allow a user to change the height of the treeview which will automatically change the height of the textbox so there is no gap between them?ie one gets bigger the other gets smaller etc etc
I have a Treeview in a form. I can add a child node, delete nodes, shift a child node by creating a subfolder in the Treeview and also change text of any child node.
How can I determine programmatically, whether one of these events/changes was occur?
I have a treeview, and lets say in the treeview I have the nodes "Textbox1", "Textbox2", and "Textbox3". Also on the form I have 3 textboxes. What I want it to do is when I click "Textbox1" in the tree, to select all text and bring focus to the first textbox. So on the AfterSelect event of the treeview, I find out what node Im on, and what textbox to go to, then I say Textbox1.Focus() : Textbox1.SelectAll().When I use the keyboard and navigate to that node, it works. It jumps the focus off of the treeview and to that textbox, selecting all it's text. Works fine.But when I click on it with my mouse, it doesn't. It does select the text, bring focus to the textbox, but immediately brings focus right back to the treeview. (you have to look really close to see it) I'm thinking there's some mouse event that is bringing the focus back to the treeview, but not sure what.
I'm trying to change the treeview image at runtime, i'm trying to apply the above code but nothing is happening. the goal is that i have an image i want to change it to another image at runtime.

Private Sub TREEVIEW2_(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TreeView1.NodeMouseHover Me.TreeView1.Cursor = Cursors.Hand End Sub I did this. But i want when i leave nodes the cursor back to default.

I have a treeview on this page of which each node has and Id and value. on selected node change event, I want to change the text of repeater selected node. I am writing code like this:
Protected Sub TreeView1_SelectedNodeChanged(sender As Object, e As System.EventArgs) Handles TreeView1.SelectedNodeChanged Dim EmployeeRepeater As Repeater = CType(Me.Form.Controls(1).FindControl("Repeater1"), Repeater) Dim EmployeeRepeaterItem As RepeaterItem

How do I reduce flicker in a vb2005 panel?Inside the parent panel I have 2 other panels that I'm am using.
The outer most panel contains a background sprite and the two innermost panels are overlays that change to fit the places in the background sprite.When I change the overlay sprites I would like to reduce the flicker and make it a smooth transition from one sprite to the next.
Here is the code that changes the images in the overlay panels the overlay panel is not changed if the new value is the same as the old value
When I set the button background image in properties, it looks great. When the button is clicked, the image needs to change. I tried to use an image list like this: btnSample.BackgroundImage = ImlStimuli.Images.Item(0)and I tried loading them from a file. I can get them to read, but the image always turns out blurry or distorted. I've tried all variations of alignment, BackgroundImageLayout like stretch/zoom/centered, and I changed flat style, but nothing has worked. Is there a setting or something that I'm missing in properties?

I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.
I am building a windows application with different languages, when I change the language of a form visual basic will create a new form for me which i can change the settings for my new language and all was working fine, but recently i recognized that the images i am changing in the other language form is changing the images in the default language form, so i need to create two Resources Folders for images and manaully tells the application which folder to use.

I am having trouble to make a form that displays the picture of the student which all his info is in a datagrid. I used the following
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' TODO: This line of code loads data into the 'BdSyngentaDataSet.Training' table. You can move, or remove it, as needed
[Code].....
It worked. But, when i click on the next student and go back to the previous, the picture is not there. When I stop the debugging and start again the picture is there but it stops displaying again after going back and forward.

i have a treeviev and listbox.i want to display the selected contents of treeview into the listbox.my code is working for file but not for folder. means i want, if the all contents of folder ABC(i.e all files) are selected then in listbox i want to show the only path of folder not the seperate path of each file.
The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]
