SendKeys

[Judgey]

Hello Guru's

Can Any of you help mw with ths one, I would like to sendkeys to a DOS App opened as a window in Win98 using a standard .pif file. I can activate and open it but sendkeys are ignored. Can somebody tell me how to go about it ?

Many thanks in anticiaption . .

Maybe you can post your code too so that we can take a look at it. There have been a lot of discussion on doing so in this forum which basically making that DOS box as the active window and using SENDKEYS to send the keyboard input.

The simplest way is such:

private Sub Command1_Click()
Shell MyDosApp.Exe, vbNormalFocus
SendKeys "My_Dos_Command{ENTER}", false ' returns right after key is sent
SendKeys "My_Dos_Wait_Command{ENTER}", true ' does not return until the command is processed by
' MyDosApp.exe
End Sub

I don't like send keys in general. here the program how to create a console and read and write to it

'that is bus module (no forms), project starts in sub main

Hi Louri,

Thanks for your code, I think its a bit advanced for me though, I can't quite fatham out how I incorporate the companies Dos EXE file, It is basically a login Name and Password, then a series of Menus which can be activated by a Letter or arrow keys. It is a true DOS App not the DOS environment, can the writeconsole be used to send strings to the DOS Application ?

Cheers Coolbiz,

This is the Code I already have and nothing seems to happen ?, anyother Ideas ?

Post the code that you currently have or email it to me. I'll take a look at it.
