MFC and VC++

[gear26926]

Hi,

The above code generates a window and it has a few buttons on it.That is working fine.
But however the part of the code where class "FileDialog" is defined and the function
"myButton5_Click" is used, it does not seem to work.

The output should be such that - When the browse(myButton5) is clicked, a dialog should be opened.

It would be great if anyone can let me know what is wrong with that part of the code as the code was working before I added that class.

Thanks in advance

You have no ON_BN_CLICKED in your Message map. Add an ON_BN_CLICKED(your button ID, function to call)

Hi,

After adding the "ON_BN_CLICKED(IDC_BUTTON1,&MFC_Window::Button1_click)", I get the error:

Not sure how to solve the type cast error.It would be great if you could help me in using the static_cast.

FYI

I am using Visual studio 2008 with .Net Framework Version 3.5 SP1

Levy,

Could you please have a look at the next post i posted for MFC and VC++ problem.
Your feedback/suggestion would be of great help to me.
