This looks like a duplicate but hear me first. This is more on the debugging side. I'm trying to remove the borders of my window using the method <a href="https://stackoverflow.com/questions/2398746/removing-window-border/2400467#2400467">here</a>. What are some things that will make these functions not work? Hiding windows using <code>ShowWindow(Handle, SW_HIDE)</code> doesn't work also. I've made my own Window class with many functions so I don't wanna paste my whole code here. Here's my Initialization function for the window: <pre><code>HRESULT SampleWindow::InitializeSimple(SampleWindow* win) { HRESULT hr; HWND hWnd; SampleWindow* sampleWin; sampleWin = new SampleWindow(); aMWindowProps->Center(); hWnd = CreateWindowEx( NULL, aMWindowProps->aWindowClass, aMWindowProps->aWindowTitle, WS_OVERLAPPEDWINDOW, aMWindowProps->aRealLeft, aMWindowProps->aRealTop, aMWindowProps->GetRelativePosWidth(), aMWindowProps->GetRelativePosHeight(), HWND_DESKTOP, NULL, *aMWindowProps->aHInstance, sampleWin); aMWindowProps->aHwnd = &hWnd; hr = hWnd ? S_OK : E_FAIL; win->aHwnd = &hWnd; //ShowWindow(hWnd, SW_SHOWNORMAL); return hr; } </code></pre> <code>WindowProps</code> as you can see contains various info about the window being created. I also have a <code>HWND</code> pointer variable in my class which points to the window handler. Here are some things I've tried on my main, where sw2 is a pointer to my window class: <pre><code> ShowWindow(*sw2->aHwnd, SW_SHOW); //ShowWindow(*sw2->aHwnd, nCmdShow); LONG lStyle = GetWindowLong(*sw2->aHwnd, GWL_STYLE); lStyle &= WS_POPUP; //lStyle &= ~(WS_CAPTION | WS_THICKFRAME | WS_MINIMIZE | WS_MAXIMIZE | WS_SYSMENU); SetWindowLong(*sw2->aHwnd, GWL_STYLE, lStyle); //ShowWindow(*sw2->aHwnd, SW_MINIMIZE); //ShowWindow(*sw2->aHwnd, SW_HIDE); //ShowWindow(*sw2->aHwnd, SW_HIDE); //SetWindowLong(*sw2->aHwnd, GWL_STYLE, GetWindowLong(*sw2->aHwnd, GWL_STYLE) && ~ WS_BORDER && ~ WS_SIZEBOX && ~ WS_DLGFRAME); SetWindowPos(*sw2->aHwnd, HWND_TOP, sw2->aMWindowProps->aRealLeft, sw2->aMWindowProps->aRealTop, sw2->aMWindowProps->aRealWidth, sw2->aMWindowProps->aRealHeight, SWP_FRAMECHANGED); //LONG lExStyle = GetWindowLong(*sw2->aHwnd, GWL_EXSTYLE); //lExStyle &= ~(WS_EX_DLGMODALFRAME | WS_EX_CLIENTEDGE | WS_EX_STATICEDGE); //SetWindowLong(*sw2->aHwnd, GWL_EXSTYLE, lExStyle); //SetWindowPos(*sw2->aHwnd, NULL, 0, 0, 0, 0, SWP_FRAMECHANGED | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOOWNERZORDER); </code></pre> I'd just like some suggestions on where to debug my code. I know the functions work as I've tested it on a much simpler window project (sample project from Microsoft).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
