QuestionCannot max/min untitled dialog box Pin
champ2327-Sep-07 19:46
champ2327-Sep-07 19:46 
I have done an untitled dialog box in MFC,
Clicking on this dialog button on taskbar, window does not minimize or maximize.
To handle this i have written code in OnNcActivate message.
My problem is that, when i say ShowWindow(SW_SHOWNORMAL); at that time the window
is shown but again it gets minimized. It does not get hold.
Please try the code, let me know what is the problem.

Here is the following code
BOOL CRestoreDlg::OnNcActivate(BOOL bActive)
{
BOOL b2 = FALSE;
TBBUTTON tbButton;
HWND hWndBut = NULL;
WINDOWPLACEMENT wndpl;
HANDLE hProcess = NULL;
LPVOID lpRemoteBuffer = NULL;
DWORD dwProcessId = 0, dwThreadId = 0;

memset(&wndpl, 0, sizeof(WINDOWPLACEMENT));
memset(&tbButton, 0, sizeof(TBBUTTON));

GetWindowPlacement(&wndpl);
HWND hDesktop = ::GetDesktopWindow();
HWND hTray = ::FindWindowEx(hDesktop , 0, _T("Shell_TrayWnd"), NULL);
HWND hReBar = ::FindWindowEx(hTray, 0, _T("ReBarWindow32"), NULL);
HWND hTask = ::FindWindowEx(hReBar, 0, _T("MSTaskSwWClass"), NULL);
HWND hToolbar = ::FindWindowEx(hTask, 0, _T("ToolbarWindow32") , NULL);

// obtain the count of buttons on toolbar
LRESULT count = ::SendMessage(hToolbar, TB_BUTTONCOUNT, 0, 0);

// obtain taskbar process id - by window
dwThreadId = GetWindowThreadProcessId(hToolbar, &dwProcessId);

// open taskbar process
hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);
if (NULL == hProcess)
{
return FALSE;
}

// for loop to recognize our application button on task bar
for (int i= 0 ; i < count ; i++ )
{
memset(&tbButton, 0, sizeof(TBBUTTON));

lpRemoteBuffer = VirtualAllocEx(hProcess, NULL, sizeof(TBBUTTON), MEM_COMMIT, PAGE_READWRITE);
if (NULL == lpRemoteBuffer)
{
return FALSE;
}

// get button info
::SendMessage(hToolbar, TB_GETBUTTON, i, (LPARAM)lpRemoteBuffer);

b2 = ReadProcessMemory(
hProcess,
lpRemoteBuffer,
(LPVOID)&tbButton,
sizeof(TBBUTTON),
NULL);
if (FALSE == b2)
{
return FALSE;
}

// Retrieve window handle of pressed btn
BYTE localBuffer[BUFFER_SIZE];
BYTE* pLocalBuffer = localBuffer;
DWORD_PTR ipLocalBuffer = (DWORD_PTR)pLocalBuffer;

// window handle
pLocalBuffer = localBuffer;
ipLocalBuffer = (DWORD_PTR)pLocalBuffer;

// initialize remote buffer
DWORD_PTR lpRemoteData = (DWORD_PTR)tbButton.dwData;

// and read the dwData fields of a TBBUTTON from remote process
ReadProcessMemory(hProcess, (LPVOID)lpRemoteData, (LPVOID)ipLocalBuffer, sizeof(DWORD_PTR), NULL);

// obtain window handle
// copy first 4 bytes

HWND windowHandle;
memcpy(&windowHandle, (void *)ipLocalBuffer, 4);

if (windowHandle == m_hWnd)
{
if (tbButton.fsState & TBSTATE_PRESSED)
{
if (wndpl.showCmd == SW_SHOWMINIMIZED)
{
ShowWindow(SW_SHOWNORMAL);
//wndpl.showCmd = SW_SHOWNORMAL; 
//SetWindowPlacement(&wndpl);
}
else if (wndpl.showCmd == SW_SHOWNORMAL)
{
ShowWindow(SW_SHOWMINIMIZED);
//wndpl.showCmd = SW_SHOWMINIMIZED; 
//SetWindowPlacement(&wndpl);
}
}
}


VirtualFreeEx(hProcess, lpRemoteBuffer, 0, MEM_RELEASE);
}

CloseHandle(hProcess);

return TRUE;
}
