how to close all child windows in MDI?
like the VC->windows->Close All command
|
|
|
|
|
EnumChildWindows maybe helpful.

CMDIChildWnd *pMDIActive;
while( pMDIActive = MDIGetActive() )
{
pMDIActive->SendMessage(WM_CLOSE);
}

yes,I did it with following code:
BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam)
{
::SendMessage(hwndChild,WM_CLOSE,0,0);
return TRUE;
}
void CMainFrame::OnWindowCloseall()
{
// TODO: 在此添加命令处理程序代码
::EnumChildWindows(m_hWndMDIClient,EnumChildProc,0);
}

thank you for your reply.
I found anoter function:
CDocTemplate* pTemplate = pDocument->GetDocTemplate();<br />
pTemplate->CloseAllDocuments(true);
though I don't know the progress of the function.

I'm glad you found this. I can't believe that EnumChildWindows() and SendMessage() were suggested.

Dear All,
I have an application which interacts with DLL inturn to a driver..
So when I press a button(named Load Driver) I should call a dll function.In this function i need to display a message that driver is loading and this displayed message should disappear after few minutes...
For displaying this message i created a dialog ( using createDialog) and destroyed it after few minutes,But the problem is, the control (here static text) inside this dialog is not displaying and this createdialog tries to use
dialog which i have in application .DLL is win32 prog..

is ur dll created with MFC? if yes, add this AFX_MANAGE_STATE(AfxGetStaticModuleState()); at the beginning of your exporting function in dll.

What part of "Dll is not Using MFC." did you miss?

if u r using HWND CreateDialog(HINSTANCE hInstance,LPCTSTR lpTemplate, HWND hWndParent,DLGPROC lpDialogFunc); to create a dialog, make sure the parameter hInstance is correctly dilivered, it must be the dll module's instance.

BOOL WINAPI DllMain(HANDLE hinstDLL, DWORD dwReason, LPVOID lpvReserved); the first parameter is the dllmodule's instance.

Are there any other controls on the dialog that are not being displayed? If so, it sounds like a secondary thread is needed as the UI thread is too busy servicing other messages.

Did you saw MSDN for LNK2001
From the MSDN:
"unresolved external symbol "symbol"
Code references something (such as a function, variable, or label) that the linker can't find in the libraries and object files."

Add your cpp file to your solutions explorer (I'm assuming you're using VS7.1), or File View (if using VS 6.0).
This tells the compiler where to find the implementation of the class definitions.

CSentenceArray is not the same thing as CSentenceList.

I figured it out.
1) To hide the menu, according to the source code of CDocTemplate, we have to do this way:
pDocTemplate = new CSingleDocTemplate(
0,
RUNTIME_CLASS(CTextEditorDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CTextEditorView));
2) Then we will see the icon of the application not being loaded. We have to load it in CMainFrame::OnCreate.
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
