User Lib Help...PLEEEEEAAASSS!!!!!!

Everytime I try to call a function I made, I get an error that sais:"User lib not found." What should I do?? I already made the .dll and .decls file.

Did you put them under Blitz3D\userlib folder?

Also when running from the IDE place the dll (if it uses one not included on windows) on the userlibs folder too; when running the EXE, place the dll on the same folder.

Yes.



Yes.

Still. When I run it, it gives me an error that sais: "User lib not found."

What are the names of the dll and decls files you are trying to use?

I think the IDE only looks for userlibs when it starts. So be sure you have run the IDE after putting the DLL and decls file in the necessary folder(s).

If that's not the problem then try a simple test. Get a DLL/decls set that you are sure works, for example the little MS Visual C/C++ demo that you find on this page. Does that work properly?

Why????? Does it matter????????

Is it a secret?

Perhaps if they're publicly-available then people who are kind enough to attempt to help you with your problem might be able to see if they work correctly on their machines, and perhaps tell you about pitfalls you need to be aware of when using them.

Ok LineOf7s. Thanks :) I'll post the code as soon as I find it :)

[edit] Found it :)

Here is the .decls file:

.lib "GIZMOWPTEST.dll"

GIZMessageBox(message$, message2$):"_GIZMessageBox*2@8"

And here is the .dll file:

#Include <windows.h>
#Include <stdlib.h>
//#Include "time.h"

#define NOTHING 0
#define Null 0
#define UNASSIGNED 0
#define NONE 0
#define DOESNT_HAVE_ONE 0
#define ALL_INSTANCES 0
#define GIZMWCN "GIZMO"
#define GIZMWCS (CS_HREDRAW | CS_VREDRAW)
#define GIZMWS (WS_OVERLAPPEDWINDOW)
#define BBDECL extern "C" _declspec(dllexport)
#define BBCALL _stdcall

WNDCLASSEX GIZMWC;
HWND GIZMW;
Int main_window_startx = 300; //starting left/right position of the window
Int main_window_starty = 300; //starting up/down position of the window
Int main_window_startwidth = 800; //starting width of the main window
Int main_window_startheight = 600; //starting height of the main window


BBDECL void GIZMessageBox(char *messagetodisplay, char *title)
{
	MessageBox(messagetodisplay,title,MB_OK);
}

Do WHATEVER you want with them. Even sell them if you want, but I know they aren't good enough to sell ;) Any help why that message pops up would be GREATLY appreciated :D

This bit in the decls looks wrong:
"_GIZMessageBox*2@8"
Should be:
"_GIZMessageBox@8"

Thanks :) But that is not the problem with the error I'm getting.

This is wrong in the source:
BBDECL void GIZMessageBox(char *messagetodisplay, char *title)
Should be:
BBDECL void GIZMessageBox(const char *messagetodisplay, const char *title)

Thanks markcw :)

Is it working now then?

Nope :(

This is wrong, you're missing the hwnd parameter:
MessageBox(messagetodisplay,title,MB_OK);
Try:
MessageBox(0,messagetodisplay,title,MB_OK);

It still sais 'User lib not found'.

Are you using .net c++ or c++ 6.0 ?? I no that .net dll's dont work with blitz3d

I have no idea. I made it in Notepad :|

I don't mean to offend you but are you compiling your C source file as a shared library from a C IDE, or just renaming the .txt extension to .dll? If the latter then that won't work.

No offense taken :) I'm new to C programming. Anyway, I renamed a .txt to a .dll :| I'll try creating one in visual studio and compiling it. How would you sudjest creating and compiling a .dll and .decls??

To create a .dll, you name your source file with a .c or .cpp extension and then tell your compiler you want to build a dll from that source. The .decls is just a text file for the Blitz IDE to read.

To use Visual Studio, read the tutorial here.
