How would you let the user of a program enter an unlimted amount of numbers ranging from 0-100, and then have the program tell the user the highest and lowest values from the data they entered?The user would enter the data in when they clicked a button, and the program would sort the data out when another button was clicked.
View 8 RepliesI am dynamically creating an unlimited number of background workers and would like to handle errors from them.
In a try statement I am using the following:
Catch ex As Exception
'Me.BeginInvoke(New UpdateTextCallback(AddressOf Error_Text), New Object() {Message, Account})
Exit Sub
End Try
I have commented out the BeginInvoke command because I can not get it to work. I get an error the the handle has not been created. This subroutine is in a module and I can not figure out how to get the invoke to work.
How can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.

View 1 RepliesI 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 3 RepliesI decided to make a module to store all my Sub's for populating a TreeView on my main form. My question is, how do I make the Module.vb where I'm storing these Subs recognize the TreeView on my main form? I'm going to create subs such as this:
Public Sub Populatetest()
Dim _GeneralNode1 As TreeNode = TreeView1.Nodes.Add("Test")
End Sub
1. I need to be able to store the STR MG INT and SPD somewhere when they create an item and make sure it is assigned to that item, and since I allow them to create unlimited item, I need this way to be dynamic (as in create variables as needed).
2. I need to find some way to make sure the user has selected an item name in the treeview (not type or main node).For example, they need to click Hockey Mask and then click the equip item button for it to work?

i have a treeview say TV1 and another Treeview Say TV2.. Now TV1 Contains all nodes for user rights. and i want to add to tv2 only selected nodes.Like TV1 is
Node 1
....Child of Node 1 (Level 2)
.........Child of Child of Node 1 (Level 3)
what i want is that when i select Level3 Node it should chek TV2 for the parent of this node. if parent exist it should add the node under the same parent. if parent does not exist it should check for Level 1 Node and if it exist it should add Level 2 Node and then Level 3 Node. Otherwise it should add Level 1 , Level 2 and then Level 3 Nodes in order.
I have a class, let's call MyClass. In this class, I have a TreeView property let's call myTreeView..In my code, I populate the Nodes of this TreeView so I can use it later on.Then, when it's time to actualy use it, I haven't been able to take all the nodes from myClass and put them in a Tree View Control on my form.[code]The weird thing is that when debugging, the TreeView in MyClass is well populated with the proper values and in the loop, newNode isn't empty, there's actually something but for some reason it's not showing anything.

View 12 RepliesThe TreeView uses in its underlying implementation the TreeNodeCollection. The TreeNodeCollection in almost every overload of the add method asks for a key.It also implements indexOfKey and ContainsKey yet there appears to be no way to determine the key of a node from the node itself or from any of the events you would typically use such as TreeView_AfterSelect().
Am I correct or is there in fact someway to retrieve the key from a node or event which I have overlooked? And assuming I am correct. Why on earth was it implemented in such a way? The only thing I could think of was that perhaps TreeNodeCollection.Key is deprecated? But I see no mention of this...
PS: I am aware of the TreeNode.Tag property and how it can be used to the same effect.

I'm working with a TreeView in a VB.NET to C# conversion project. I have this VB.NET WinForms code
Dim Arguments1 As String = path & "" & fs & " ls " & TreeView1.Nodes(ccc).Name
and I need the C# code. I got this far
string args = path + "\" + fs + " ls" + ...
I would assume it would be
.Items[ccc]
but there is not name attribute in that
