Return Value

If the value exists, this function returns TRUE. If the value does not exist or a registry key has not been previously opened this function returns FALSE.

Example Code

// Open the Brass registry key for the current user
if(regOpenKey("HKCU", "Software\\32Bits\\Brass") == True)
{
    // Does the ConfirmExit value exist in this key?
    if(regCheckExists("ConfirmExit") == True)
    {
        // Act on ConfirmExit value
    }
    else
    {
        // ConfirmExit doesn't exist, perform action
    }
}
