problem to get Notepad's ImmGetContext

VB Code:

Private Declare Function ImmGetContext Lib "imm32.dll" (ByVal hwnd As Long) As Long 
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal Classname As String, ByVal WindowName As String) As Long 
 
Private Sub Command1_Click() 
dim hwnd as long,hIMC as long 
hwnd = FindWindow("Notepad", vbnullstring)
if hwnd<>0 then
hIMC=ImmGetContext(hwnd) 
msgbox hIMC 
end if
end sub

but hIMC always return 0,how can i get notepad 's ImmGetContext,anyone can help me? :(

What is notepad's ImmGetContext? What is an ImmGetContext?

I have never worked with IME so my knowledge is rather vague. First, is the IME program installed on your computer. If it is, I think it's the Notepad edit window that is provided with IME.

As I said, my knowledge is vague.

What is IME? What are you trying to do? Get the text in an open notepad window?

Input Method Manager (IMM): http://msdn.microsoft.com/workshop/m...w/overview.asp
Input Method Editor (IME): http://www.microsoft.com/windows/ie/...e/default.mspx
IME reference: http://msdn.microsoft.com/library/de...l/ime_1mat.asp

ImmGetContext
Returns the input context associated with the specified window.

HIMC ImmGetContext(
HWND hWnd
);
Parameters
hWnd
[in] Handle to the window for which to retrieve the input context.
Return Values
Returns the handle to the input context.

Remarks
An application should routinely use this function to retrieve the current input context before attempting to access information in the context.

------------------------------------------------------

the problem is if hwnd isn't myself process,then this APIdoesn't work

if i set hwnd = FindWindow("", "Form1") or hwnd=form1.hwnd or hwnd=text1.text
it's both work
if hwnd is external process's hwnd,then it's doesn't work:(
anyone can help me?

maybe can use c++ write a dll,this dll can get ImmGetContext,then use VB inject this dll to notepad,but i don't know how to write it in c++....

So you want to get the text that is typed in a notepad instance, right? Try searching for the FindWindow, FindWindowEx and GetWindowText APIs.
