in making a combobox - treeview - checked in visual basic. I have seen a few examples in c++ but I am unable to convert that code. Nor do I know how to integrate ++ code into my project. So, where do I start? Custom control? Is there a custom control project at startup of visual studio?
View 3 RepliesI trying to get what I think should be a simple thing. I have a checked treeview. I need to get the text of each checked node into a string. For the life of me I can't get it. I am trying to loop thru all the nodes and see if they are checked but I keep getting a "object reference not set to an instance of an object" but I don't know why.
Dim value As String
Dim node As TreeNode
Dim i As Long

user can select all node in treeview.i got some code from internet, but i don,t know what is that.(I'm new one).
public void OnCheckChanged(Object sender, TreeNodeEventArgs e)
{
if (EntertainmentTreeView.CheckedNodes.Count > 0)

I have a treeview control with check boxes. when I check the parent node, all the children check too. The problem is, I want the parent check box to automatically uncheck if one of the children is unchecked.
Private Sub TV_Communities_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TV_Communities.Click
For i = 0 To TV_Communities.Nodes(0).Nodes.Count - 1
If Not TV_Communities.Nodes(0).Nodes.Item(i).Checked Then
TV_Communities.Nodes.Item(0).Parent.Checked =
False
End If
Next
End Sub

I am displaying all checked nodes from treeview1 like........
Private Function GetCheck(ByVal node As TreeNodeCollection) As ArrayList
Dim lN As New ArrayList
For Each n As TreeNode In node
If n.Checked Then
lN.Add(n)
Else
lN.AddRange(GetCheck(n.Nodes))
End If
Next
Return lN
End Function
It works properly. But If I prints checked nodes. Then again if I un-check any checked node from already checked nodes and now. If I print then I don't get the exact checked nodes. It still shows me previous output. What should I have to do for getting the exact checked nodes?

View 1 RepliesI decided to explore deeper into how blank forms and controls are created.I don't know where to start. I'm not expert by any means I believe I just now the basics.I tried and start new project but instead of windows form template I used Blank Project. Added a module and creating sub main.I created a new class and copied few lines from a previous project and it gave me several errors.Brushes, Color, Font, Graphics are not defined. I am not sure if it's correct but when I added System.Drawing Reference and System.Drawing Namespace the errors was removed.Moreover, 'My' is not declared.
I would like to know what basic references and namespaces I need to add.(Note: I tried to add all the referenced and namespaces found when I create a windows form project but the errors was not removed)Moreover, how to create my own form and controls.
I have a treeview with nodes being represented as checkbox.
All works fine i.e when a parent nod is checked, its child and sub child should be checked as well but it won't check only the first subchilds and i am not able to find the solution, i have debugged it many time, but still not able to figure the solution.
I tried finding the solution on the web, but didn't got the proper solution. Below is the code which i am using in my form.

I'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.
I'm trying to use a TreeView in my current project and I'm not quite sure if it will work.I need my tree view to load the TreeView with the contents of the C: drive. Along with this, I need the nodes to be "checkable" so that I can tell my program to do certain things with items checked. Can this be done? If not with TreeView, is there somethings that is free that is an add-in that I can use?

I'm loading a folder (path), which contains folders and files, in a treeview according the combobox-text.
When I load the app. the combobox is filled with the paths. I'm using the SelectedIndexChanged to load the treeview. Everything works.
The issue is that it also starts to load the paths the treeview also gets loaded (slow), but it should only load when I select an item in the combobox.
I tried comboboxselectedtextchanged etc, but without any luck. Besides that loading the files and folders is slow.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.

I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
In a listview with check boxes, there are two fields being loaded, ID and Lastname. With this information I want to get the ID of the person whose box is checked with this sub:
