Passing HWND as a parameter via constructor or function

How can I pass the HWND of the main window via a constructor or function from the winmain to a class.  when I do I get the following error upon linking:

error LNK2001: unresolved external symbol "public: void __thiscall FileDialog::OpenTheFile(struct HWND__ *)" (?OpenTheFile@FileDialog@@QAEXPAUHWND__@@@Z)

thanks in advance.

It seems that you declare FileDialog::OpenTheFile member function in the header file but forget to specify FileDialog when you define OpenTheFile function in the source file.

Is your code like this?

void OpenTheFile(HWND)
{
    // your code here
    // ...
}

It should be like this.

void FileDialog::OpenTheFile(HWND)
{
    // your code here
    // ...
}

Can you please provide more info? Class declaration and function implementation would be most helpful.
