我一直在改进我一直在研究的课程，其中一个是创建库来处理某些在我的主项目中不需要看到的任务。但是，当我调用该类并实例化我刚创建的库时，我得到：
Intellisense：类型“HWND”的参数与参数不兼容 类型为“rawData :: HWND”
当我从库中调用一个方法并传递这些参数时，会发生这种情况（错误在第一个参数中）：
// register the window for touch instead of gestures
rawData::RegisterTouchWindow(hWnd, 0);
此处的完整代码：
//Creates the main window
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = szWindowClass;
wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_APPLICATION));
if (!RegisterClassEx(&wcex))
{
MessageBox(NULL,
_T("Call to RegisterClassEx failed!"),
_T("Win32 Guided Tour"),
NULL);
return 1;
}
hInst = hInstance; // Store instance handle in our global variable
// The parameters to CreateWindow explained:
// szWindowClass: the name of the application
// szTitle: the text that appears in the title bar
// WS_OVERLAPPEDWINDOW: the type of window to create
// CW_USEDEFAULT, CW_USEDEFAULT: initial position (x, y)
// 500, 100: initial size (width, length)
// NULL: the parent of this window
// NULL: this application does not have a menu bar
// hInstance: the first parameter from WinMain
// NULL: not used in this application
HWND hWnd = CreateWindow(
szWindowClass,
szTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
800, 600,
NULL,
NULL,
hInstance,
NULL
);
if (!hWnd) {
MessageBox(NULL,
_T("Call to CreateWindow failed!"),
_T("Win32 Guided Tour"),
NULL);
return 1;
}
// register the window for touch instead of gestures
/*ERROR HERE*/rawTData::RegisterTouchWindow(hWnd, 0);/*ERROR HERE*/
// the following code initializes the points
for (int i=0; i< MAXPOINTS; i++){
points[i][0] = -1;
points[i][1] = -1;
idLookup[i] = -1;
}
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
// Main message loop:
MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return (int) msg.wParam;
}
我去了几个网站，他们建议使用“this-＆gt;”指定您指向的变量但在我尝试时没有显示。这就是为什么我来这里看看是否有人遇到过这种情况。任何一点点帮助都是最值得赞赏的。提前谢谢！

答案 0 :(得分：1)
通过将所有内容放在您自己的namespace rawTData中，您已声明所有这些类型都属于rawTData。 HWND是一种Windows API类型，不等同于您的定义（rawTData::HWND）命名空间不仅仅是用于包装一堆您不想要的智能信息为了表明，他们将名称“隐藏”在类似目录的结构中。一个简单的解决方法是将namespace rawTData {向下移动到您自己的声明之上，但它引出了一个问题：为什么要在namespace rawTData中包装所有？
看起来您已经将一堆Windows.h定义剪切并粘贴到您自己的命名空间中。你真的应该只包括适当的文件。如果这不起作用，可能还有其他需要解决的问题，你不应该像这样通过复制粘贴来削减它。
