[Dev-C++] ANSI C++ forbids implicit conversion from "void*"

[metalseb <met...@fr...>]

Hi there

Compiling a small project to help one of the subscriber, I had the following bad surprise:

I downloaded the CStaticHyperlink class from codebytes but when I try to compile the class, I 
get this message from the compiler :

"ANSI C++ forbids implicit conversion from void* when passing parameters"

The error occurs at the line where there is the CreateWindowClassEx of the hyperlink window 
control in the class constructor. I cannot understand what's wrong. And I cannot understand 
either what does this message tries to tell me.

Anybody could help ?

Kind regards

You need to cast the void * when calling the function. Example:

int function(int x) {
	// do something
}

int main(void) {
	void * x = NULL;

	// function(x); // no

	function( (int) x); // okay
}
