[RESOLVED] Portability

[suizVisual]

Hello Friends, I have the next problem.

When I programm this simple application to generate a Window, I get an executable file. If I run the executable file on other computer, I get an error message "Can not find the component", "Didn't find the MSVCR100d.dll". Why can't I run the application on other computers? Thanks!!

#include "stdafx.h"
#ifndef UNICODE
#define UNICODE
#endif 

#include <windows.h>

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow)
{
    // Register the window class.
    const wchar_t CLASS_NAME[]  = L"Sample Window Class";
    
    WNDCLASS wc = { };

    wc.lpfnWndProc   = WindowProc;
    wc.hInstance     = hInstance;
    wc.lpszClassName = CLASS_NAME;

    RegisterClass(&wc);

    // Create the window.

    HWND hwnd = CreateWindowEx(
        0,                              // Optional window styles.
        CLASS_NAME,                     // Window class
        L"Learn to Program Windows",    // Window text
        WS_OVERLAPPEDWINDOW,            // Window style

        // Size and position
        CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,

        NULL,       // Parent window    
        NULL,       // Menu
        hInstance,  // Instance handle
        NULL        // Additional application data
        );

    if (hwnd == NULL)
    {
        return 0;
    }

    ShowWindow(hwnd, nCmdShow);

    // Run the message loop.

    MSG msg = { };
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}

LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;

    case WM_PAINT:
        {
            PAINTSTRUCT ps;
            HDC hdc = BeginPaint(hwnd, &ps);

            FillRect(hdc, &ps.rcPaint, (HBRUSH) (COLOR_WINDOW+1));

            EndPaint(hwnd, &ps);
        }
        return 0;

    }
    return DefWindowProc(hwnd, uMsg, wParam, lParam);
}

It doesn't run because the computer where you run it does not have the required VC++ DLLs (in this case the C/C++ runtime, but it can also be MFC or ATL, depending on your app type). See this FAQ with links to redistributables to install on that machine: http://www.codeguru.com/forum/showthread.php?t=494136.

However, notice that you are trying to run a Debug build. That won't work with the redistrituables from the above FAQ. You need to build and deploy a Release configuration.

Well, I have installed redistributable packages for VC++ Studio 2010. But it still don't work. I am working with Visual Studio C++ 2010 Express, and i don't know how to do it, and how to build and deploy a Release configuration.... Can you help me please?? Thanks!!

At the top in Visual Studio there is a dropdown box where you can select Debug and Release.
Set that to Release and to a rebuild.
It's against the EULA to distribute a Debug build of your applications.

Ok now it's works!!! sorry I am a beginner programming in Visual C++. Thank you very much!

How I said, I'm new programming in visual studio. I have programming in C/C++ and Java in Linux, but I would like programming in Windows, Process and Drivers and so on. I am following the guide of msdn, http://msdn.microsoft.com/en-us/libr...=VS.85%29.aspx. Do you recommend me another guide?? Thanks you very much

No. Maybe some books about Windows programming.
