Hi Arjen,

I am not 100% sure,
but I think in V7 there was a special SEK necessary
to access "Operating System Command"

A better way to prepare for modernisation:

Centralise the spawn commands in a group of global procs (sync, async).
When you go to higher versions, there is only one place to change the code.

Success, Uli

Thanks, Uli for your quick response.

I will ask around in "the organization" (i.e. Dirk Jan) if a special SEK is needed. This would indeed explain the negative $status I keep getting back.

Centralizing the spawn commands before modernization / migration is a good idea indeed.

Regards, Arjen

Hi,

Perhaps i don't understand your pb, but you can use ShellExecuteA.

This is a solution here http://www.uniface-dev.com/pdf/internet_1.pdf

Hi Jérôme,

Thank you so much; works like a charm!

I roughly followed your description in  http://www.uniface-dev.com/pdf/internet_1.pdf, but without the handle (no valid file type in 7.2.0.6).

It basically comes down to something like : activate "SHELL32".SHELLEXECUTE(0, "open", COMMAND, PARAMS, DEFDIR, 1)

With this there is no need any more to use an "Operating System Command" type of signature and therefore no need for another SEK. 

Cheers!

Arjen
