Antonio:
You could send just one string using a format similar like this:
Yes; that's what I was planning to do anyway
To do it, just include this function in your DLL:
Compiling with buildhd.bat I get an error:
Error E2141 dlltest 41: Declaration syntax error
*** 1 errors in Compile ***
just after #include <hbapiitm.h>. However, the DLL gets built. Is that normal?

It's compiling Ok now. Many thanks for your fast answer. I'll try it with VB and I'll let you know the results...

Antonio has suggested a way to make my DLL accesible from Visual Basic that just completes the receipt to make DLLs callables from another language. Just add the following to the .prg:
Code: Select all | Expand
long _export pascal TEST( char * cProcName, char * cParam )
{
PHB_ITEM pItem = hb_itemPutC( NULL, cParam );
hb_itemDoC( cProcName, 1, ( PHB_ITEM ) pItem, 0 );
hb_itemRelease( pItem );
return 0;
}
and declare the DLL in VB as follows:
Declare Function TEST Lib "C:\Path\MyDll" (ByVal cProcName As String, ByVal cParam As String) As Long
Then, from VB5 just call the function as always:
I'm sure many people will find this info valuable. Thanks a lot, Antonio!
