在对话框中没有获取列表视图(列表控件) [英] Not getting List view(List Control) in DialogBox

问题描述

// This is the the file for list view. I am passing handle of List Control to this function.

	fInsertListViewColumn(hwndLV, 0, 30, TEXT("A (column)"));
        fInsertListViewColumn(hwndLV, 1, 30, TEXT("B (column)"));

        fInsertListViewItem(hwndLV, 0, 0, 0, TEXT("A1(item)"));
        fInsertListViewItem(hwndLV, 1, 0, 0, TEXT("A2 (item)"));
}

当我删除列表控件对话框显示但在对话框中添加列表视图(列表控件)后，它不起作用.
在Windows 7中同样可以正常工作.请尽快帮助我.必须在明天早上之前完成我的项目.

推荐答案

您是否呼叫了InitCommonControlsEx()?

希望这会有所帮助，

Pablo.

Did you call InitCommonControlsEx()?

Hope this helps,

Pablo.

这应该放在您的InitInstance函数中:

This is what should go into your InitInstance function:

// InitCommonControlsEx() is required on Windows XP if an application
// manifest specifies use of ComCtl32.dll version 6 or later to enable
// visual styles.  Otherwise, any window creation will fail.
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
// Set this to include all the common control classes you want to use
// in your application.
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);

我认为自动生成的注释说明了它的作用.在Windows 7下，操作系统会自动为您执行此操作.在XP下，必须按上述步骤进行操作，否则创建通用控件的任何窗口都会失败.

I think the automatically generated comments explain what it does. Under Windows 7 the operating system does this automatically for you. Under XP it needs to be done as shown above, otherwise any window creation of a common control will fail.
