“无法打开输出文件名.exe：权限被拒绝”(“cannot open output file fil

我刚学C ++，我试图让使用windows.h头的程序。我现在用的开发 - C ++编译器和我收到三个错误，我无法找到一个解决方案。

这些都是错误的：

无法打开输出文件名.exe：权限被拒绝
[错误] LD返回1退出的目标状态配方“文件名.exe”失败

这里是我的代码：

#include &#60windows.h&$62
#include &#60iostream&#62
#include &#60fstream&#62
#include &#60string&#62
#include &#60vector&#62
using namespace std;

HWND textfield;
/* This is where all the input to the window goes to */
LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam) {
switch(Message) {
    case WM_CREATE:

            CreateWindow("STATIC",
            "DocJoin Document Combiner",
            WS_VISIBLE | WS_CHILD | WS_BORDER,
            20,20,300,25,
            hwnd,NULL,NULL,NULL);
            break;

    /* Upon destruction, tell the main thread to stop */
    case WM_DESTROY: {
        PostQuitMessage(0);
        break;
    }

    /* All other messages (a lot of them) are processed using default procedures */
    default:
        return DefWindowProc(hwnd, Message, wParam, lParam);
}
return 0;
}

/* The 'main' function of Win32 GUI programs: this is where execution starts */
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int     nCmdShow) {
WNDCLASSEX wc; /* A properties struct of our window */
HWND hwnd; /* A 'HANDLE', hence the H, or a pointer to our window */
MSG Msg; /* A temporary location for all messages */

/* zero out the struct and set the stuff we want to modify */
memset(&wc,0,sizeof(wc));
wc.cbSize        = sizeof(WNDCLASSEX);
wc.lpfnWndProc   = WndProc; /* This is where we will send messages to */
wc.hInstance     = hInstance;
wc.hCursor       = LoadCursor(NULL, IDC_ARROW);

/* White, COLOR_WINDOW is just a #define for a system color, try Ctrl+Clicking it */
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszClassName = "WindowClass";
wc.hIcon         = LoadIcon(NULL, IDI_APPLICATION); /* Load a standard icon */
wc.hIconSm       = LoadIcon(NULL, IDI_APPLICATION); /* use the name "A" to use the project icon */

if(!RegisterClassEx(&wc)) {
    MessageBox(NULL, "Window Registration Failed!","Error!",MB_ICONEXCLAMATION|MB_OK);
    return 0;
}

hwnd = CreateWindowEx(WS_EX_CLIENTEDGE,"WindowClass","DocJoin",WS_VISIBLE|WS_OVERLAPPEDWINDOW,
    CW_USEDEFAULT, /* x */
    CW_USEDEFAULT, /* y */
    683, /* width */
    730, /* height */
    NULL,NULL,hInstance,NULL);

if(hwnd == NULL) {
    MessageBox(NULL, "Window Creation Failed!","Error!",MB_ICONEXCLAMATION|MB_OK);
    return 0;
}

/*
    This is the heart of our program where all input is processed and 
    sent to WndProc. Note that GetMessage blocks code flow until it receives something, so
    this loop will not produce unreasonably high CPU usage
*/
while(GetMessage(&Msg, NULL, 0, 0) > 0) { /* If no error is received... */
    TranslateMessage(&Msg); /* Translate key codes to chars if present */
    DispatchMessage(&Msg); /* Send it to WndProc */
}
return Msg.wParam;

}

我花了3个小做研究和故障排除，我只是难倒。这是我第一次使用C ++编译器，这意味着它的我的第一个程序。

Answer 1:

你必须改变文件的位置。

注意：不要保存在文件Program Files和Program Files (x86)在Microsoft Windows。

您可以使用例如另一个路径C:\USER\.....

Answer 2:

链接器无法删除现有文件filename.exe 。
