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

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
    // ...
}
