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 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.

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?

View 3 RepliesI 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.

Can it be done? if yes, how do i gonna bring it over? i only manage to make a windows pop out only. but cant bring the data over.

View 4 RepliesFirst forms project. My textbook [wrox VB 2880 Programmer's Reference, Rod Stephens] gives snippet that starts with [which intnellisense completes, except for variable names, including trailing 'paint' which seems to be the problem]
Public Class Form1

which generates error :
Error 1 Method 'Private Sub form1_paint(sender As Object, e As System.Windows.Forms.TableLayoutCellPaintEventArgs)' cannot handle event

Changing 'Private' to 'Public' does not fix the error.
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 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.
I have a windows application that has a tab control with 5 different tabs. Each of these tabs has a datagrid view that is populated with data on form load with data from SQL Server. I have an event handler for the datagrids for CellValueChanged that appends an asterisk, "*" to the tab, when a change is made, this is meant to mimic the same behavior in VS or SSMS. The issue that I have just realized is that on page load as the datagrids are populated this event handler is raised thousand of times. I have included an If Then statement to exit the sub if it occurs during page load, but am concerned about the performance implications, if any. Is there a better way to handle such functionality? Possibly a way to ignore the event handler on form load? If not is there a negative impact leaving this functionality in?
