Can I have text as resultvalues from Call DLL Function?


Is this possible?

No, you cannot do this. You will need to pass text in one of the function parameters, using the allocated string buffer type.

Hello

I can not figure out how to make this work:

Delphi Code:

Code: Select all

function GETCLIENTID(var CLIENTID: PChar): boolean; stdcall;
begin
  StrCopy(CLIENTID, PChar('Test Result'));
  result := true;
end;

Script Code:

Code: Select all

Set Variable ARESULT to False
Set Variable CLIENTID to 
Call DLL Function $SUPPORTDIR$\\testdll.dll->GETCLIENTID (get result into variable ARESULT)

or as clipboard text:

~InstallAware Clipboard Data~
~Call DLL Function~
~{D358BB08-5A01-403B-8ACF-68597B36CB04}~
~$SUPPORTDIR$\\testdll.dll,GETCLIENTID,bool,ARESULT,"allocated string buffer (MAX_PATH length)",$CLIENTID$,$~
~mIDEFunc.dll\\mEXEFunc.dll~

I can not get this to work in IA18. I've searched these forums for over an hour. I'm sure I just don't have something configured correctly. Is there a clear solution/example/guide for doing this with Delphi? It should show the IA and the Delphi side of things. Thanks.

Dear User,

Honestly, I don't understand which is your problem with using the command ... anyway, you'll not find a Delphi sample with this forum.
