I know how to detect when the Shift key has been pressed so I turn on an indicator then I can put upper case characters in the text box but I have no idea how to know/detect when the user has released the shift key.
In autoitscript I used the following method:
I'm not sure if it could apply, but you could try checking if the getasynckeystate <> shift key.Code:do
;nothing
until ( the shift button is pressed)
Checking if <> shift key will occur since the next key coming in will be a character like a, b, c, etc.
The problem is I can detect when the shift key was pressed and that allows me to make the characters upper case but I have not found a way to detect if the shift key has been released so I can make the characters lower case again.
When the shift key is pressed I set an indicator to tell my code to make all characters upper case until the shift key has been released. Since I have not been able to detect this and not reset the indicator the characters keep printing in upper case even though they shift key has long been released.
Put this code to module
put this in a timer , make the interval 100Code:Public Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
these are the codes for the key codes

goodbye,Code:If GetAsyncKeyState(VK_LSHIFT) Then ' if shift pressed do bla bla bla

That doesn't solve the problem that is the problem.Quote:

OK, I'll try subclassing the edit control (which is just a Textbox) and see if I can get a grip on this. I'll post back later when I get an answer to this approach - Thanks for the suggestion.Quote:
