Hi,
How can I send ctrl keys (like ctrl A, ctrl C) from a VB application to
another existing application (like word, excel...) ? I tried to send
postmessages like
postmessage(hwn d,WM_KEYDOWN,vk _control,code)
postmessage(hwn d,WM_KEYDOWN,"A ",code)
postmessage(hwn d,WM_KEYUP,"A", code)
postmessage(hwn d,WM_KEYUP,vk_c ontrol,code)
I tried several codes according to documentation like 0 and xC..., the
target windows does receive the codes (checked with spy++) but doesn't
execute the ctrl key command. Did I do something wrong ? is there
another way ?
Thanks so much for whom may help me.

Example.
'The function is declared as a form class member.
Private Declare Function SendMessage Lib "user32.dll " Alias "SendMessag eA"
(ByVal hWnd As IntPtr, ByVal wMsg As Int32, ByVal wParam As Int32, ByVal
lParam As Int32) As Int32
Const WM_VSCROLL As Int32 = &H115
Const SB_LINEDOWN As Int32 = 1
Const SB_LINEUP As Int32 = 0

Thanks,
It doesn't work more, I used sendmessage and after postmessage as I saw
in spy++ that keyboards events came with post.
My functions declarations are as follow :
Public Declare Function PostMessage Lib "User32" Alias "PostMessag eA" _
(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal
lParam As Long) As Long
Public Declare Function SendMessage Lib "User32" Alias "SendMessag eA" _
(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal
lParam As Long) As Long
What I just can't understand is that the result is exactly the same from
my soft and from the keyboard, checked with spy++ when I send
vk_control/vk_insert/vk_insert/vk_control to simulate a copy command.
What is more strange, is that when I replace vk_insert with "C", I get
the four actions + the c character, which looks like the targeted
windows didn't interpretate the keystroke as I thought.
thanks for all advices !

Your declares are wrong for VB.NET. Replace all 'As Long' with 'As
Int32', 'hwnd' can be declared as 'IntPtr'. Remove the 'Alias...' and
declare the function as 'Auto'.

Hi, there is an application running on a remote desktop (under Citrix ICA,
but the same problem applies for RDC or PC Anywhere). Now, I want to send
keys to the remote application from a local app. I tried sending keys in VB
with SendKeys, as well as using keybd_event API, but I'm not able to send
any keys. It works very well for any local applications, but I can't pass
the keys remotely. Is there any way to do it?
Thanks!
Etienne

MDI WinForms 2 application.
I need that Ctrl+F1 cycles through windows like Ctrl+Tab and Ctrl+Tab is
redefined.
I overrided MDI child form OnKeypress method but Ctrl+F1 press is ignored.
For unknown reason base.ProcessCmdKey calls method itself.
How to fix ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
