无法从本地路径加载msvcr90.dll

问题描述

我正在尝试构建一个示例Win32 Exe应用程序，我在其中从C：\ProgramFiles（x86）\文件夹加载msvcr90.dll。但这是在抛出错误。我的目的是从应用程序的路径而不是C：\ Windows \ WinSxS文件夹加载msvcr90.dll。但是不能这样做。



我尝试过：

I am trying to build a sample Win32 Exe Application in which I am loading msvcr90.dll from C:\ProgramFiles(x86)\ folder. But it is throwing error. My purpose is to load msvcr90.dll from application's path instead of C:\Windows\WinSxS folder. But not able to do so.

What I have tried:

int APIENTRY _tWinMain(_In_ HINSTANCE hInstance,
                     _In_opt_ HINSTANCE hPrevInstance,
                     _In_ LPTSTR    lpCmdLine,
                     _In_ int       nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);

    // TODO: Place code here.
    MSG msg;
    HACCEL hAccelTable;

    // Initialize global strings
    LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
    LoadString(hInstance, IDC_DEMO_LOAD_EXE, szWindowClass, MAX_LOADSTRING);
    MyRegisterClass(hInstance);

    // Perform application initialization:
    if (!InitInstance (hInstance, nCmdShow))
    {
        return FALSE;
    }

    DWORD dwError = 0;
    SetLastError(dwError);
    LoadLibrary(L"C:\\Program Files (x86)\\<myapp>\\<myapp1>\\msvcr90.dll");
    dwError = GetLastError();


    hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_DEMO_LOAD_EXE));

    // Main message loop:
    while (GetMessage(&msg, NULL, 0, 0))
    {
        if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))
        {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
    }

    return (int) msg.wParam;
}

推荐答案

Quote：

LoadLibrary（LC：\\Program Files（x86）\\< myapp> \\< myapp1> \\ msvcr90.dll）;

dwError = GetLastError（）;

LoadLibrary(L"C:\\Program Files (x86)\\<myapp>\\<myapp1>\\msvcr90.dll");
dwError = GetLastError();

您提供的路径无效（'<'和'>'
您明显忽略 GetLastError 返回值。

You are providing an invalid path ('<' and '>' are not allowed in paths).
You are plainly ignoring the GetLastError return value.
