Do you know what it means logical units at the help (MSDN) of StretchBlt ?

int myInt = 0;

{
  int myint = 1;
}

cout << myInt;

In this example, will it make a difference if I take out the braces?

Also, I have a sample code with no braces in the for loops? I thought braces were required, but the code compiles and does what it is supposed to do.

for(int x=0; x<353; x++)
{
    brightnessSum+=frameBuffer[x+353*y]; 
}
 
for(int x=0; x<353; x++)
    brightnessSum+=frameBuffer[x+353*y];

Is there a reason for using braces if they are not part of a condition or loop? For example:

//
// Some Code Getting Ready To Process Something...
//
{
    CMyHeavyweight myobjObject;
 
    myobjObject.DoYerThang( true );
}
//
// Some Code After Processing Something...
//

if( bFailed )
   statement1;
   Bugfix Statement1; // Will get executed always.

I have 7 child dialogs, & a parent dialog. From parent dialog, I call 1st child, on the child dlg's buttons child sends message to the parent. Among that one message is to update the object in parent which is working fine. The second message is to hide that child and show another child dialog.

void CParentDialog::ShowChildDialog() 
{
    CDialogDlg ChildDialog;
    if( SHOW_NEXT_DIALOG == ChildDialog.DoModal())
    {
        // Show your next child dialog.
    }
}

// In child dialog
void ChildDialog::OnNextDialog() 
{
    // The SHOW_NEXT_DIALOG will be returned by the DoModel() call.
    EndDialog( SHOW_NEXT_DIALOG );
}

Jijo, I can't add an int, float to CString. Like I want to add up "Name " + int + float in a CString. How do I achieve it. I tried many ways, but gives error or warnings only. Help me if you can.

CString csMessage;
int nInteger = 10;
float fFloat = 20.0f;

// Format the message.
csMessage.Format( _T("%s %d %f"), // Format String.
                  _T("Name :"),
                  nInteger, 
                  fFloat );
// if you want to format the float precision, just use %0.2f in format string.
// So only two decimal digits will be shown.
