SendKeys.Send("%{TAB}") how do i say which window or number to goto ?
Hello Vartana,
Let us say you have 8 windows open, and the 1rst is your own program, the code to normalize all windows is in this case:
(Here you return to your own window):
--------------------------
Dim n As Integer
Dim tabs As String
For n = 2 To 9
tabs = tabs & "{tab}"
Next
SendKeys.Send("%(" & tabs & ")") '>>> In this case the command is: SendKeys.Send("%({tab}{tab
--------------------------
NOTE: Let n=2 !! Since our own program is always window 1, you can better start off with n=2. The 9 means: 9-8=1 You return to window 1.
>> IF you want to go to window 2:
--------------------------
Dim n As Integer
Dim tabs As String
For n = 2 To 2
tabs = tabs & "{tab}"
Next
SendKeys.Send("%(" & tabs & ")")
--------------------------
This means you execute the ALT-TAB commando once.
>> AND if you want to go to window 6:
--------------------------
Dim n As Integer
Dim tabs As String
For n = 2 To 6
tabs = tabs & "{tab}"
Next
SendKeys.Send("%(" & tabs & ")")
--------------------------
But if you want to go to window 6, also this code works:
>> AND if you want to go to window 6:
--------------------------
Dim n As Integer
Dim tabs As String
For n = 2 To 14
tabs = tabs & "{tab}"
Next
SendKeys.Send("%(" & tabs & ")")
--------------------------
Since: 14-8=6

btw, use this page if u wanna know more about keystrokes and how they work:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformssendkeysclasstopic.asp
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformssendkeysclasstopic.asp
Btw.: you might need you app to wait in between the keystrokes. This is because the keystroke need some time to execute. Use this module like this:
wait(300) 'wait 300 msec
So you code would be:
--------------------------
Dim n as integer
for n=1 to Number_of_Windows
SendKeys.Send("%{TAB}")
Wait(300)
Next

The module you have to add to your project:
