How to automate response to msgbox

Question

I am developing a C # application to automate running an outdated VBScript (vbs) file that calls multiple VB6.exe files. The .exe files have message box pop-ups that I need to “reply” to allow the VBScript process to run unattended. The answer should be the Enter key. I have no source for the .exe files, and I don’t know exactly what they are doing. I would really appreciate any help on this ...

Answer 1

After spending the last 2 days trying to achieve this, I finally gave up and decided on a different approach. I will interrogate the data that is sent to the external process and looks at it for conditions that cause pop-ups of the message box. Thanks to everyone who answered with the answers!

You can find AutoIt .

AutoIt v3 is a free OS-OS scripting language designed to automate the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement, and window / control controls to automate tasks in a way that is possible or reliable with other languages ​​(like VBScript and SendKeys).

, , SetWinEventHook PInvoke , . , . WINEVENT_OUTOFCONTEXT, , , . , , EVENT_SYSTEM_DIALOGSTART.

Once you get hwnd from the dialog box (from the event list), you can use SendMesssage with WM_COMMAND or WM_SYSCOMMAND to get rid of it.

Answer 6

Using the sendkey method, pass the keyboard key value and continue.
