Hi,

I am getting this error : Error opening DLL library PEGRP32A.DLL for external function at line 28 in function f_create of object u_process32_dll.

The external function is declared as: Function ulong PEcreate(uint nControl,uLONG dwStyle, ref rect2 theloc, uLONG hParent, uint nID) LIBRARY "PEGRP32A.DLL" alias for "PEcreate;Ansi"

The PB app is a 64-bit executable so I am thinking that's why it is not able to work with the 32-bit DLL.

How can this issue be resolved ? Is there a 64-bit version of this DLL available ? 

Thanks,

Gurtej

Have you tried to use "progma_pack(1)" ?

Function ulong PEcreate(uint nControl,uLONG dwStyle, ref rect2 theloc, uLONG hParent, uint nID) LIBRARY "PEGRP32A.DLL" alias for "PEcreate;Ansi" progma_pack(1)

Hi.

It seems to be a very old version of ProEssentials Graphic Presentation library (Shopping ProEssentials Charting Components (gigasoft.com)).

Andreas.

I did search for a 64-bit version of this DLL but no luck.

You will likely have to contact Gigasoft.com to inquire. Is there a reason why you are migrating to 64-bit? Perhaps you might consider keeping the app as 32-bit for now until you find a 64-bit replacement DLL.

Okay, I will contact Gigasoft.com to inquire.

We migrated our app to 64-bit a long time ago. The graph is a very small portion of the app and rarely used so we didn't encounter this error till now.
