I've got a struct
Code:
struct lpar{char a, b, c, d;};

and I need to pass it to a function as a LPARAM.
Whenever I try, I get
Quote:
`struct lpar' used where a `LPARAM' was expected

I've tried several different ways to get it to take it, but none of them are accepted. How can I make this work?

Besides the structure, code would help.

Code:
#include <windows.h>
struct lpar{char a, b, c, d;};
void AFunc(LPARAM c){return;}
int main(){
lpar var;
AFunc(var);
return 0;}

It's rather hackish, but here:

Code:
#include <windows.h>

typedef struct lpar {
    char a, b, c, d;
} LPAR;

void AFunc(LPARAM c)
{
    return;
}

int main()
{
    LPAR var = { 1, 0, 0, 2 };
    AFunc((LPARAM)*((DWORD*)&var));
    return 0;
}

Rofl. Thanks, Flyte, that's actually working.

@samuri25404
Same thing happened when I tried casting. Tried casting to LPARAM, as DWORD then LPARAM, as LONG then LPARAM. Tried making a function that took the lpar and returned it as an LPARAM. No luck with any of it.
