vb6.exe Application Error !? Origin ?

Hello,

I have designed a VB program that calls a C DLL.
Each time I call a function from the DLL, VB crashes with the following error:

vb6.exe Apllication Error
The instruction at "0x0FB3191D" referenced at "0x00000000".
The memory could not be read.

What could be the origin of this error and what's the solution ?

Thanks in advance.

Depends on how you declared them functions.

You can't reference a C dll into your vb app.

The functions must be declared in the general declerations section and used with the correct params.
The names of the C dll can contain unrecognized words.
ie underscores at the beginning cannot in vb then you have to use an alias

Thank you for your advices.
I have already checked this. Nothing is wrong.
I really don't know the origin of the problem.
