Hi Everyone,

I am using PowerBuilder 2017 R2. I want to run an another application which is written in C# in my powerbuilder windows application. Want to click on a button with 2 string input parameter and also need to get the return value of the application.

I tried below code but its not working:-

string ls_1, ls_2
ls_1="abc"
ls_2=""
run("PMFC.exe "+ls_1+" "+ls_2+")

Please suggest.

 

Thanks,

Mukul

Hi Mukul,

Run() won't help you with Exitcode handling of external apps, you need a Run&Wait API.

Google for "run and wait powerbuilder" or "CreateProcess powerbuilder" to get some examples.

Here 2 links you can start from:

https://answers.sap.com/questions/11629053/run-and-wait.htm

Best,

A program can only return a number 'the return code'. Anything other than that would have to be saved somewhere that the caller can read once the external app is finished.

The built in Run function doesn't wait for the external app to complete, it immediately goes to the next line of code.

I have a Run And Wait code example you can try:

http://www.topwizprogramming.com/freecode_runandwait.html

It allows for getting the return code from the external app. If you want to return more detailed info, you can put it in the database or in a file to be read by the caller.
