Im trying to display the bitmap image in the dialog box. First time when i press the button it displays the image. Next time when i press, it shows the build assertion failed error.

This is the add button click function.

C#

void CsampleStudDlg::OnBnClickedAdd()
{

UpdateData();
Bmp.LoadBitmap(IDB_ADD);
m_Picture.SetBitmap(Bmp);
UpdateData(FALSE);
}

what i need to do is, to display the image whenever i press that button.

Thanks in advance..

UpdateData(); is same as UpdateData(TRUE);

You are not getting me, see this and try:
void CsampleStudDlg::OnBnClickedAdd()
{
Bmp.LoadBitmap(IDB_ADD);
m_Picture.SetBitmap(Bmp);
UpdateData();
}

What is the assertion and where does it occur?

Bmp is a member of your class: this way you are loading and loading again the image without calling DeleteObject.

Thank You. Got the result

You are welcome.
Please note, if you don't need to change the loaded resource then does not make sense loading/deleting it all the times. Load the resource once and let the Bmp destructor deleting it.
