将控件添加到C ++ Win32中的TabControl中的特定选项卡页

BlueFlower 发表于 Dev

我想在tabcontrol的标签页中添加一些控件，但是似乎它将被添加到所有页面，并且默认情况下tabcontrol中没有标签页。

我在下面阅读了这些链接，但是它们并没有帮助我，在某些地方，使我感到困惑。

如何将控件添加到Tab控件

这是我的代码：

[代码]：

#define ID_LBL 500              
#define ID_BTN 501              
#define ID_TBC 502              

HWND hWnd;

void InserTabItem(HWND handle, LPWSTR text, int id)
{
TCITEM tci = { 0 };
tci.mask = TCIF_TEXT;
tci.pszText = text;
tci.cchTextMax = wcslen(text);
SendMessage(handle, TCM_INSERTITEM, id, LPARAM(&tci));
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
switch (Msg)
{
case WM_CREATE:

    tab_handle = CreateWindowEx(WS_EX_CONTROLPARENT, WC_TABCONTROL, 0, WS_VISIBLE | WS_CHILD, 10, 10, 200, 150, hWnd, HMENU(ID_TBC), 0, 0);

}
break;

    break;
case WM_DESTROY:
    PostQuitMessage(0);
    break;
default:
    return DefWindowProc(hWnd, Msg, wParam, lParam);
    break;
}

return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPreviewInstance, LPSTR lpcmdline, int ncmdshow)
{
WNDCLASSEX wndexcls;
wndexcls.lpszClassName = L"win";
wndexcls.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wndexcls.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
wndexcls.hCursor = LoadCursor(NULL, IDC_ARROW);
wndexcls.hbrBackground = (HBRUSH)(COLOR_3DSHADOW + 1);
wndexcls.lpszMenuName = NULL;
wndexcls.style = NULL;
wndexcls.hInstance = hInstance;
wndexcls.cbSize = sizeof(WNDCLASSEX);
wndexcls.cbClsExtra = 0;
wndexcls.cbWndExtra = 0;
wndexcls.lpfnWndProc = WndProc;
RegisterClassEx(&wndexcls);

hWnd = CreateWindowEx(WS_EX_CLIENTEDGE | WS_EX_CONTROLPARENT, L"win", L"TestApp", WS_OVERLAPPEDWINDOW, 100, 100, 640, 380, 0, 0, hInstance, 0);
ShowWindow(hWnd, ncmdshow);
UpdateWindow(hWnd);



MSG wnd_msg;
while (GetMessage(&wnd_msg, NULL, 0, 0)>0)
{
    TranslateMessage(&wnd_msg);
    DispatchMessage(&wnd_msg);
}
return (int)wnd_msg.wParam;

}

我正在寻找安全正确的实施方案。

谢谢你的帮助

问题是，在调试之后，该应用程序将退出并且不显示任何内容。如果我对OnSelChanged（hWnd）和OnChildDialogInit（hWnd）进行注释，则该应用程序将正常启动，并显示tabcontrol，而不显示页面上的控件。看来问题出在这里。

输出日志：

  First-chance exception at 0x00BE1886 in testcppapp.exe: 0xC0000005: Access violation reading location 0x00000014.
 The program '[16220] testcppapp.exe' has exited with code 0 (0x0).

我已阅读以下有关访问冲突阅读位置的链接：

但是我无法解决问题。

请发布您的答案并对此进行解释，而不仅仅是简短的评论！

一个问题在这里：

pHdr->hwndDisplay = CreateDialogIndirect(hInstance_Win_Global, 
    (DLGTEMPLATE*)pHdr->apRes[iSel], hwndDlg, DialogProc);

您正在对主对话框和子对话框重复使用相同的对话框过程。主对话框创建子对话框，子对话框使用相同的过程创建子对话框...也没有错误检查。

除此之外，这段代码太复杂了。只需在主窗口中使用一个对话框即可。创建一个新对话框，IDD_DIALOG1然后在其中拖放选项卡控件。分配IDC_TAB1标签控件ID。尝试从以下代码开始：

#include <Windows.h>
