Hi guys,

Got this warning:

warning C4800: 'int' : forcing value to bool 'true' or 'false' (performance warning)


Want to tidy it up, here's the line affected:


bool bResult = pDlg->CB_IsOurCustomBrowser();




What would I need to do?


Cheers!

Hi Cyber-Drugs,
> What would I need to do?

Try the following:
bool bResult = pDlg->CB_IsOurCustomBrowser()?true:false;

What is return type of CB_IsOurCustomBrowser? If this is int or BOOL, this warning is shown, because int is casted to bool. Notice that BOOL is defined as int32 value, and bool is one byte. There are three ways to correct this:

BOOL bResult = pDlg->CB_IsOurCustomBrowser();

bool bResult = (pDlg->CB_IsOurCustomBrowser() != 0);

bool bResult = (bool)pDlg->CB_IsOurCustomBrowser();
