There is something strange going on in my VB 2005 program that I don't understand.. I have a form that has several tab pages. Each page has one or more DataGridView controls. When a user selects an item on one DataGridView , I want to deselect anything currently selected on any other DataGridView on that tab page. The only thing that should then be selected is the item I clicked on in the current DataGridView .
I created the following code (note there is a CellContentClick handler for each DataGridView control and there are DeselectAll... and RefreshAll... subroutines for each tab page).
It's fairly straightforward. But notice where I placed the XXX NOTE comment below. If I place a breakpoint there, run the program and click on various cells in various grids, and then click on the specified grid cell, I can create situations where the breakpoint is never reached! Thus, I don't turn off the selection in other grids.
How can this be? Is there some setting for DataGridView controls that I've inadvertently set incorrectly (without my listing them all here)? Or is there some bug in VB I'm unaware of? The "DeselectAll" subroutine merely iterates over all DataGridView controls in the current tab page (except for the current DataGridView) and calls ClearSelection on each such grid. RefreshAll calls Refresh on every DataGridView on the current tab page.

I'm having troubles with my datagridview. Id like to use a combobox that you could type into and (as you are typing) would update the drop down list with the ability to use wildcardsThe list is populated with a table in my database. I know how to do this using just a combobox on a form, but I'm still learning everything with datagridviews.Is there a way to do this with a combobox in datagridview? If not, is there a way to do it any other way (i.e. using a textbox and having something pop up like the autocomplete windows)? I really would like to have the ability to use wildcards with this

I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.

I have an ASP.Net web user control which represents a single entry in a list. To allow users to reorder the items, each item has buttons to move the item up or down the list. Clicking on one of these raises an event to the parent page, which then shuffles the items in the placeholder control.Code fragments from the list entry:
Public Event UpClicked As System.EventHandler
Protected Sub btnUp_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Handles btnUp.Click
[code]....
It originally looked in testing like every other time the value for sender (verified by its properties) that reaches UpClicked is of an adjacent ListItem, not the one I've just clicked on - the first click is always wrong, then the second for the correct control.At present,testing appears to show that the button's click event is just being ignored every other time through.Breakpoints on the click events within the control simply aren't being hit, though the events are definitely being established.

I want to make something like an alarm clock. So, I want my programe to trigger a certain event at lets say, 8:00 AM and 16:00 PM.
I was thinking something with timers ticking every second and checking if the time I want is equal to the system time. But....I didn't manage to make it work. So, how do I make this work ?

take a shot from a camera every last day of the month at midnight. I know how to to take the shot, but I don't know how to generate an event repetitively after a time period. I thought about to calculate the time between now and the next shot time, but how to run a method after a time period?

I have a TreeView object on my form, with check boxes. By the way, I'm working with vb.NET. I want it to perform a few different things with the aftercheck event:
If you check a node, check all its children
If you uncheck a node, uncheck the parent node
If you uncheck a node, uncheck all its children
The problem is when you uncheck a node, it unchecks its parent node, which triggers the event again and unchecks all its children.
Would there be a way to prevent the event from triggering a second time? Or will I have to give up on one of those two points?
Here's the code, if it helps any:
If e.Node.Level > 0 Then
If e.Node.Checked = False Then
If e.Node.Parent.Checked = True Then
[code]....
While I'm at it, is there a way to check if a folder is accessible? I've toyed with FileAttributes, but can't seem to find out how to make it work...

I have a VB (.NET3.5) project like this:
- form1: IsMDIForm = true.
- form2: adding a list view with 2 records, select first record, and register the event ItemSelectionChanged.
- Add form2 as a child of form1 (form2.MDIParent = form1).
- When use "form2.Show()" -> the event ItemSelectionChanged firing three time:
+ 1st: SelectedItem = 1
+ 2nd: SelectedItem = 0
+ 3rd: SelectedItem = 1
I want to know the rootcause (not Solution) of thi issue, can anyone help me !?

I have a form for which the form load event only fires one time. When the program starts. It will not fire again until I end the program and restart. I have tried .show and .showdialog, but it acts the same. I have read about form load events loosing the handles, but my code looks exactly like it should.
Here is the load event code
PrivateSub frmBilling_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
LoadClients()
LoadTherapists()
LoadCPT() EndSub
Here is the code that calles the form.
PrivateSub BillingToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BillingToolStripMenuItem.ClickfrmBilling.Show()
frmbilling.show()
EndSub

I'm having a strange problem with the OnClick event. In an ArcGIS application using VB.Net, I have a button set up with the following
AddItem("CommandAnalyseResults")
The following module segment contains the OnClick event: Public NotInheritable Class CommandAnalyseResults
Inherits BaseTool <more code...>
Public Overrides Sub OnClick()
[Code]...
The OnClick event gets triggered no problem the first time I click on the button. However if I then close the window the button code creates and then click on the button again, the OnClick code is not triggered.
If I click on a different button then click back on the 'problem' button a 2nd time, it does seem to trigger the code!

I have a UserControl with a Panel (Panel1). The UserControl has a property Items (type ControlCollection) that returns the Controls collection of Panel1.Via a custom CollectionEditor, I tell the designer that it should add my custom controls called Item (inheriting Control). For the sake of example, the Item control is just a control with a random background color:[code]The custom CollectionEditor creates new Item controls using the DesignerHost service (and its CreateComponent method), so that they appear as actual components in Panel1, selectable during design-time just like any other control.It might be a little hard to see (because the colored Items are docked to the top), but I have selected the red item, which can also be seen from the Properties list.
As you can see in the code, I attach a Click event handler to each item as it is added to Panel1. When clicked, a MessageBox shows the color of the item. Obviously this is just for the sake of this example, but the point is that I need to be able to click an item and something then needs to happen.This works fine during run-time. I can click each item, and the MessageBox shows.The problem is that it does not work (quite obviously) during design-time. When I click it during design-time, it is simply selected (as any other control) and of course does not register any Click (nor MouseClick) events.But, I need the Click event to fire even when in design-time! Clicking an item corresponds to selecting it, and when selected (even in design-time), some other panel (not shown in this example) should be brought to the front so it gets visible. Now, I have created lots of things very similar to this (clicking an item during design-time), but there has always been one major difference: those items were not actual controls on the form. Instead, they were drawn manually on to their parent (and they only looked like separate controls). Obviously there was no design-time support for those 'items' (as they weren't controls), but I could handle clicking them quite easily: by handling the MouseClick event of the parent, I can check the location and see if it falls within an item. If so, that item was 'clicked' (artificially).This time, the items are actual controls, and this method does not work (the parent does not receive a MouseClick event either).So, does anyone know of any way to do this? The only way I can think of right now (although I have no idea how to implement it) is to somehow 'listen' to changes in the designer selection.
