I created an even on a form called Sub New so I can handle some events and close the window down if there is an error.Upon doing that, I came across 3 errors that I don't know how to fix.[code] ShowDialog really isn't necessary I could just use .Show. I want to use ShowDialog because the line under those 3 shows the current form.How do I pass the date to the form?In case it's relavent, my code for sub new on frmEmail.[code]

View 1 RepliesI have a problems with my application..
1. collapse and expand treeview when i click plus sign (+) on treeview, treeview didn't expand subfolder but when i click image, treeview expand it.
2. showing path that i check on treeview when i check the treeview then i'm click the button, then return path that i check
This is my code..
Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

I have a Treeview with two levels (customers , products) and I want to find by customer name... I tried the following:

This does not work... could somebody tell me what I am doing wrong.
I have a treeview that is populated with a hierarchical list of regions and locations. Each region has its own list of regions and locations - you can think of these as analogous to a folder structure in windows (ie a region is like a folder than can have subfolders and files within it).My code to populate the structure is called only once (I've put in breakpoints and stepped through the code), however my treeview shows two sets of the data. When I query how many nodes there are at the top level of the treeview it tells me there is only one node, but clearly there are two. If I delete the node at position 0 in the list of nodes one copy of the tree disappears but one still remains and it this point the count of nodes in the treeview is reported as zero.
I have a toolbar associated with the treeview which includes buttons to expand all and collapse all using the built in methods of the treeview (expandall and collapseall), and these only act on the first set of nodes and ignore the second set even though I can manually expand and collapse them at run time.I have code in the AfterSelect event of the treeview and this does fire for even the phantom nodes.The other odd thing is that the code to populate the tree assigns a key to each node, and so I would expect the code to fail if it was creating duplicate nodes as it would have duplicate keys
I am working on a project and need checkboxes on childs only.Now I have this

View 4 RepliesI have a TreeView control on a form with two Root nodes. Both root nodes use the same ContextMenuStrip. The problem I'm having is that at runtime if I right-click on the root node that IS NOT selected, and select the option to add a child node, it gets added to the node that IS selected. My code for adding the child node is below.
Is there a way to have the control first SELECT the node that was right-clicked, or at least determine which node was right-clicked?

View 11 RepliesMakes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?

View 3 RepliesI'm going through my company's program making sure that all icons have tooltips. We have a lot of grids with icons, but in case the settings for the tooltip to show up are not there, the column header should have the same tooltip as the icon. In regular grids I just click the column header, and then the properties for it show up in the bottom right corner in Visual Studio. However, we have some treeviews, and when I click on the column header of a column in the treeview, Tooltip is not among the properties I can edit. How to make a tooltip show up on such a column header?
