I have no idea what you just said there^

It's precisely 10:57pm EST here Stateside.
As such, that's roughly 1 hour before my brain goes into Brain Dead Mode as is customary at said time.
Thus will I translate the above for you on the morrow...or maybe the morrow after the morrow.

Use the PreviewKeyDown event, because it happens beforehand...

C#, but easily, you should be able to see what i'm doing with this:

Code:

void Form1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e) { if (e.KeyData == Keys.A) { // Do something? } }

Occurs before the KeyDown event when a key is pressed while focus is on this control.

Read the Remarks as it is important, and look at the example code with the VB tab selected to view the VB.NET version.

If you want to use a Key event, there's KeyDown and KeyUp as well, but I would highly recommend KeyUp over the KeyDown, and for a few reasons.

orrrrr....

Code:

Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Integer) As Short

Code:

Public Function GetKeyState(ByVal key As Integer) As Boolean Dim s As Short s = GetAsyncKeyState(key) If s = 0 Then Return False Return True End Function

Code:

If GetKeyState(Keys.*) = True Then 'put this if statement in a thread to run through to keep a check on it. End If

This way it checks through out the whole time while running the program for a hotkey.

Perhaps, but you have to call it multiple times to make sure that it hits the time a user presses a key because it's not based on events. He wanted a hotkey for specifically a textbox as I read it. If you wanted a global system-wide hotkey, you could do it this way, but it is a very poor way, and it uses a lot of resources because it has to be called constantly.

There's much better ways, even avoiding this, and a keyboard hook, but a keyboard hook is the ultimate way in my opinion, because you don't have to register and unregister a specific hotkey that may already be taken by something else.
