UInt32 with "DLL32 Function"

[Callejas]

Hi All,

Is it possible to use the type unsigned int 32 in the calls "DLL32 FUNCTION" ?

I need to declare the following call in the harbour:

in C#:
[DllImport("PCSHLL32.dll")]
public static extern UInt32 hllapi(out UInt32 Func, StringBuilder Data, out UInt32 Length, out UInt32 RetC);

I tried with several types (WORD, DWORD, LONG, _INT) but without success.

can anybody help me?

thanks

PS: Sorry my english

LONG should work. Probably the problem is elsewhere.

Hi, EMG.

Thank you for the answer. I am making the declaration in the following way:

DLL32 FUNCTION _hllapi(@F AS LONG, @D AS STRING, @L AS LONG, @R AS LONG) AS LONG PASCAL FROM "hllapi" LIB "PCSHLL32.dll"
but it doesn't work.
I got to write a dll "wrapper" in C for access the dll "PCSHLL32.dll" without the type uint32, but even so the harbour doesn't get to access.

I will continue trying.

thank you.

Callejas.

DLL32 FUNCTION _hllapi(@F AS LONG, @D AS STRING, @L AS LONG, @R AS LONG) AS LONG PASCAL FROM "hllapi" LIB "PCSHLL32.dll"

Try

DLL32 FUNCTION HLLAPI(@F AS PTR, @D AS STRING, @L AS PTR, @R AS PTR) AS LONG PASCAL FROM "hllapi" LIB "PCSHLL32.dll"

Hi EMG,

thanks, but it didn't work.

Antonio says this in a previous message:

Try it again removing PASCAL from the DLL32 declaration

(In FWH DLL32 is no longer needed. Just use DLL ... as we are in 32 bits)

What error do you get exactly?

The problem was in the registration of the dll.
Now it is working correctly.

thank you very much to all
