Windows NT and VB 'Sendkeys' function

[rogerE]

A user of an application I have written is experiencing problems. The application uses the 'Sendkeys' function to enter data into an Oracle Form from a comma delimited file.

He is running windows NT. The problem occurs in the actual entry into the Oracle Form. Some of the 'Sendkeys' appear not to work and incorrect values are entered into some of the cells on the form. This ends up causing Oracle Errors due to validation in the various cells.

All other users of the application (whether on windows NT machines or windows 95) have not experienced any problems.

Any ideas? Could this be a Windows API issue? Could focus be shifting away from the oracle form for some reason.

Any contributions gratefully accepted.

Many thanks,
Roger Eigenheer

I am using NT at work, and the only problems i have ever had with SendKeys is the focus issue. I have actually managed to crash the computer completley by sending keys when the focus was wrong.

That would be my first line of enquiry.

Cheers Iain,

I think I have the focus issue covered for most computers, there are about 150users, 1/2 of whom are NT. I was just wondering if it's perhaps a DLL issue. Is there a certain DLL on his computer which may be shifting focus differently to the standard DLLs.

Again, this has me stumped, all the standard DLLs ar there - with current versions etc.

Anyone encountered something like this before.

An leads at all greatly appreciated.

Many thanks,

Hi, I wrote an app in VB to talk to another app using sendkeys and I had the same problem your describing. I tried everything I could think of. Sometimes it would work
perfect and others times it would put wrong data in the fields. I got it working most of the time using delay's between each sendkey. I ended up scrapping the whole thing
and I purchased WinBatch, I used their sendkeys function and
never had any problems after that.

The apps were running on NT.
