External program used excel, if you click on the click of a button to send a message through the simulation, excel this call can not be started. If my program is A.exe I need to simulate an external program control after clicking B.exe this B.exe a button click can not call excel Case 1: B.exe manually click a button in excel can be a normal call! --OK! Case 2: using the SendMessage function to send a message with A.exe analog control click on the button in excel B.exe call fails, and pop-up "can not start Excel server!"! --NG! Messages sent using SendMessage is successfully sent, message "Unable to start Excel server!"! Also shows that the message was sent successfully, but it is not up calls excel! Question: permissions problem? Or anything else that needs to feed?

A.exe is my own program,B.exe is not my own program. B.exe has a button, click it, and will call to EXCEL! Now, my question is: if click this button to manually, EXCEL will be normal calls.---(OK) But if use my program(A.exe),the Sendmessage function sends a keystroke messages (WM_KEYDOWN WM_SYSKEYDOWN) on the button, EXCEL will call fails.---(NG) I'm sure it: Sendmessage function keystroke messages is sent successfully!

You need to be sure that the messages are exactly what the program uses to cause the button press.
