You need to change e.g. [ICODE]if(Addition = true)[/ICODE] to [ICODE]if(Addition == true)[/ICODE]

Try replacing the line [ICODE]PaintRoutine(hwnddc, GetPixel(hDC, pt.x + x, pt.y + y), 1, 1, 1 + x, 1 + y);[/ICODE] with [ICODE]SetPixel(hwnddc, x, y, GetPixel(hDC, pt.x + x, pt.y + y));[/ICODE]

How about managing the [ICODE]id[/ICODE] in the [ICODE]Base[/ICODE] class, i.e. [code] class Base { public: explicit Base() : id(object_count++) {} static int object_count; protected: int id; }; int Base::object_count = 0; class child: public Base { public: child(int val){} }; int main() { child c(1); return 0; } [/code]

A radical suggestion, instead of coding the games inside the switch, make the games functions and do something like [code=cplusplus] while(1) { cout << "A: To Play the number guessing game." << endl; cout << "B: To Play the letter game." << endl; cout << "C: To quit program." << …

[ICODE]#include <winresrc.h>[/ICODE] in the .rc file, that way the definitions of e.g. [ICODE]DS_MODALFRAME[/ICODE] and [ICODE]WS_POPUP[/ICODE] will be known. In addition to that, add [ICODE]#define IDC_STATIC -1[/ICODE] in the resource.h file.

I think the library you need is [I]libcomdlg32.a[/I]. Generally, when you get linker errors related to Windows API functions, lookup the function's documentation in MSDN, scroll down to the bottom of page where you can find the name of the required .lib (i.e. in this case: [I]Import library Comdlg32.lib[/I]). That …

Obviously you don't have a class named [ICODE]CMyView[/ICODE], so you cannot use the provided example as is. Instead you could e.g. make the provided example a stand-alone function and use it as such, i.e. simply [code] BOOL GetPageSize(CSize &nRetVal) { // rest of the example code here ... } [/code]
