I need to make a call to an external DLL in foxpro 3,0 for the generation of a string which soon would be forms in I code of bars (code PDF417), I do not have problems but when trying to call it an error " VFP has produced an error in pdfdf.dll " proving with another one dll when trying to execute the routine gives a message of which it does not find the entrance of the function in the DLL
 
Hi, pcmarket.

#Questions
1. Do you have a declare-dll statement?
2. Is the dll 16-bit or 32-bit?

Hi PCMarket,

Typically a 'Cannot find entry point in the DLL' is a direct result of a misspelled procedure/function name. DLL procedure/function names are case sensitive. For Example,

DECLARE INTEGER GetDesktopWindow IN win32api

is the proper syntax. The following would generate the error I mentioned:

DECLARE INTEGER GetdesktopWindow IN win32api

You may want to take a few extra minutes and reformulate your question. I read it 5 times and it still sounds like gibberish to me. Jon Hawkins
