Tabcontrol Event When The Small Tab Is Pressed?
Jan 13, 2010
I have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is). I see where an event is raised when I click on the tabpage itself. What is the event for the small tab area? I am getting by with a mousemove event over the currently selected tabpage.

How do you make an event when the small "s" key is pressed on a Windows form?
I now have the following code:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Convert.ToChar(Keys.S) Then
End If
End Sub

I have a small Windows Application that displays a .chm Help File when F1 is pressed. What I would like to do is to close the Help Display programatically for example when a Reset Button is clicked and the Form is 'Reset'.

I have alot of experience in working in VBA for excel, but not so much experience in creating my own structures so it's all still a bit foggy. I'm trying to capture the event for when the F1 key is pressed, not just when the form is active, but anytime the program is running. The code below expressing the handling is automatically generated for me in VB Express... But I'd like to change the situation to encompass anytime the program is open. I guess I have to reference events that happen in windows in general, but i don't know how to do it. I think i have to create the even in a class module?

I am running VS 2008 and building my app on a Windows 7 box. The main form/window has a KeyDown event handler as follows in it:
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
MsgBox("control = " + e.Control.ToString + ", shift = " + e.Shift.ToString + ", e.Keycode = " + e.KeyCode.ToString)
When I build it and run it within VS it seems to run fine. The messagebox appears with the state of the control and shift keys along with the key code of the key I pressed. However, if I take the executable and run it on an XP box (both using .Net Runtime 3.5) as soon as the main form opens, the messagebox appears. Basically the "KeyDown" event seems to be firing without any keys being pressed. The messagebox comes back with: "control = False, shift = False, e.Keycode = None".
How is this possible? How can the keyDown event be fired when no keys have been pressed (as is confirmed by the output contained in the messagebox?) how I can diagnose this on the XP box since it does not have Visual Studio on it?Update I tried creating a brand new project where there is only "form1" and the only code behind this is the keyDown event handler. It just opens a blank window and pops up the message box if a key is pressed. It worked as expected on the Win 7 box but when I moved the executable to the XP box, it immediately popped open the messagebox without pressing a key.

I am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?

I've been searching for the answer for this all over, but I can't seem to find the solution. I have no idea how do this. A code that triggers an event after multiple command buttons are pressed in a certain order. For example: I press Command1, then Command2, then Command8, then Command5, then an event happens. It's kind of similar to entering a code to activate something.

I have 2 listboxes on a form. Each listbox has a few items. As you know, I am able to have 1 item selected from each listbox, therefore making it 2 selected items from different listboxes.
I want to create a keyboard + mouse shortcut so I can de-select or change the selection mode of the listbox when Alt is held down and Left button on the mouse is clicked on the selected item. Here is the code that I wrote, which does not work.
Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If Control.ModifierKeys = Keys.Alt AndAlso e.Button =

I have a small database program that gets data from csv file, I created a function that formats the font color of textboxes based on dates and values.
CODE:
I place this in text changed event and I have a problem implementing it, because the date conversion will not take place until the data is loaded. The second part works but not the first(Date) part.
I can create a button and use its click event to format the text boxes just fine, however i wanted the text boxes to be formatted on the fly . The problem is no matter where i call the function the date conversion wont work.

Is it possible to assign the MouseDown event handler or equivalent to an image (from ImageList) of a tabcontrol without using OwnerDraw? I can add images to tabs through ImageList. And I can draw something that looks like a close button on each tab, using OwnerDraw. But I notice that the tab sizes will be fixed regardless of the tab labels. I want the tab sizes to be flexible with the labels. For now, the second best alternative to assign events to tabs seems to be use of contextual menus. But it's true that some people just don't want to right-button-click on tabs.And I have seen a project where somebody uses a 32-bit library declare. And I can't use it because I only develop 64-bit apps.

When I click the left or right arrow buttons on the keyboard my tabcontrol tabpage changes from one tab to another. How can I cancel the arrow buttons from changing the tab pages? In other words how can I disable the arrow buttons when the tabpage has focus? Is it possible to do this without extending the base class?

The only way I found to set the focus on a TextBox inside a TabPage is:

TextBox1.Focus()

I'm using a TabControl and have overridden the DrawItem event to produce my own background and foreground colors for the header text. It looks good but there's still grey color around each header. I thought maybe the Padding property could be set to (0,0) but that seemed to have no effect.

I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).
