 Inviato: 21 Mag 2007 09:58 Oggetto: [C++] - Caricare Form figlio in un form Padre MDI |
 |
|
Ciao a tutti,
ho trovato un esempio dal supporto microsoft per un programmino che si basa sul MDI.
questo programma apre dei documenti figlio.
Io utilizzo Visual 6 C++, e vorrei aprire un form figlio con pulsanti e checkbox..
qualcuno sa aiutarmi ?
Vi posto il codice sotto :
Questo crea il form padre
| Codice: |
BOOL CFramerApp::InitApplication(LPCSTR pszCmdLine, int nCmdShow)
{
CLIENTCREATESTRUCT clientcreate;
// 1. Register window classes...
if (!RegisterWindowClasses()) return FALSE;
InitCommonControls();
// 2. Load Menu resources...
//_hMenuOrg = LoadMenu(g_hInstance, MAKEINTRESOURCE(IDR_MAIN_MENU));
_hMenuOrg = LoadMenu(g_hInstance, MAKEINTRESOURCE(IDR_MENU));
if (NULL == _hMenuOrg) return FALSE;
_phMenus = new HMENU[FEX_MENUCOUNT];
if (NULL == _phMenus) return FALSE;
for (UINT uTemp=0; uTemp < FEX_MENUCOUNT; uTemp++)
_phMenus[uTemp] = GetSubMenu(_hMenuOrg, uTemp);
// 3. Load accelerators...
_hAccel = LoadAccelerators(g_hInstance, MAKEINTRESOURCE(IDR_ACCELERATORS));
if (NULL == _hAccel) return FALSE;
// 4. Create the main window and client-area window
_hwndApp = CreateWindow("FrameWndClass", " Prova",
WS_OVERLAPPEDWINDOW | WS_CLIPCHILDREN,
CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
NULL, _hMenuOrg, g_hInstance, NULL);
if (NULL == _hwndApp) return FALSE;
clientcreate.hWindowMenu = _phMenus[FEX_WINDOWPOPUPMENU];
clientcreate.idFirstChild = 6000;
_hwndMDI = CreateWindow("MDICLIENT", NULL, WS_CHILD | WS_CLIPCHILDREN | WS_VISIBLE,
0, 0, 0, 0, _hwndApp, NULL, g_hInstance, (LPSTR)&clientcreate);
if (NULL == _hwndMDI) return FALSE;
// _hwndStatus = CreateStatusWindow(SBARS_SIZEGRIP | WS_CHILD | WS_CLIPCHILDREN | WS_VISIBLE, "Ready...", _hwndApp, 2);
_hwndStatus = CreateStatusBar(_hwndApp);
if (NULL == _hwndStatus) return FALSE;
// 5. Make us all visible.
ShowWindow(_hwndApp, nCmdShow);
UpdateWindow(_hwndApp);
return TRUE;
}

Poi quando dal menu uno seleziona "New File" :
| Codice: |
STDMETHODIMP_(BOOL) CFramerApp::NewFile(WORD wDocType)
{
CLSID clsid = {0};
BOOL fHaveCLSID =FALSE;
// Create a new document object to host embedded object...
CFramerDocument* pv = new CFramerDocument(_dwNumDocs++);
if (pv == NULL) return FALSE;
// If the user chooses New from toolbar, we'll try to create a new
// object of the same type the user is currently working with, so
// get the CLSID for the active object...
if ((wDocType == IDM_FILENEW) && (_pipaobj))
{
IPersist* ppst = NULL;
if (SUCCEEDED(_pipaobj->QueryInterface(IID_IPersist, (void**)&ppst)))
{
ppst->GetClassID(&clsid);
ppst->Release();
fHaveCLSID = TRUE;
}
}
// If we can create the child window to the MDI frame...
if (pv->CreateDocWindow(_hwndMDI))
{
BOOL bSuccess = TRUE;
switch (wDocType)
{
case IDM_FILENEW_EXCEL:
bSuccess = pv->CreateNewDocObject(CLSID_EXCELWORKBOOK);
break;
case IDM_FILENEW_EXCELCHART:
bSuccess = pv->CreateNewDocObject(CLSID_EXCELCHART);
break;
case IDM_FILENEW_PPT:
bSuccess = pv->CreateNewDocObject(CLSID_PPTPRESENTATION);
break;
case IDM_FILENEW_WORD:
bSuccess = pv->CreateNewDocObject(CLSID_WORDDOCUMENT);
break;
case IDM_FILENEW:
if (fHaveCLSID)
bSuccess = pv->CreateNewDocObject(clsid);
// fall through to default - create debug window...
}
// If we have a doc object, show the window and return TRUE...
if (bSuccess)
{
pv->ShowDocWindow();
return TRUE;
}
}
// If here, we failed for some reason - notify the user...
MessageBox(_hwndApp, "Cannot create a new object!", "New", MB_ICONHAND);
pv->CloseDocWindow();
return FALSE;
}
STDMETHODIMP_(BOOL) CFramerDocument::CreateDocWindow(HWND hwndMDIClient)
{
//TRACE1("CFramerDocument[%d]::CreateDocWindow()\n", _dwDocId);
MDICREATESTRUCT mdic; ZeroMemory(&mdic, sizeof(MDICREATESTRUCT));
CHAR szDocName[50];
wsprintf(szDocName, "Document%d", _dwDocId);
HRESULT hr = CreateBindCtx(0, &_pbctx);
if (FAILED(hr)) return FALSE;
hr = StgCreateDocfile(NULL, STGM_TRANSACTED | STGM_READWRITE | STGM_SHARE_EXCLUSIVE |
STGM_CREATE | STGM_DELETEONRELEASE, 0, &_pstgfile);
if (FAILED(hr)){_pbctx->Release(); return FALSE;}
mdic.szClass = "SingleDocHandle";
mdic.szTitle = szDocName;
mdic.hOwner = g_hInstance;
mdic.lParam = (LPARAM)this;
_hwndMDI = hwndMDIClient;
_hwndDoc = (HWND)SendMessage(_hwndMDI, WM_MDICREATE, 0, (LPARAM)(LPMDICREATESTRUCT)&mdic);
if (NULL == _hwndDoc) return FALSE;
ShowWindow(_hwndDoc, SW_HIDE);
_bstrDocName = ConvertToBSTR(szDocName);
return TRUE;
}
STDMETHODIMP_(BOOL) CFramerDocument::ShowDocWindow()
{
// If we have an OLE object, but haven't yet gone
// inplace active, go inplace first...
if ((_poleobj) && (!_pipobj))
IPActivateView();
// If the window is hidden, make it visible...
if (!_fVisible)
{
ShowWindow(_hwndDoc, SW_SHOWNORMAL);
_fVisible = TRUE;
}
// Update windows...
RedrawWindow(_hwndDoc, NULL, NULL, RDW_INVALIDATE | RDW_FRAME);
InvalidateRect(_hwndMDI, NULL, TRUE);
UpdateWindow(_hwndMDI);
// Set the window name for the MDI child window...
UpdateTitleBar();
return TRUE;
}

In questo modo mi apre un documento vuoto di testo..
io invece vorrei caricare un form che ho gia creato, che sia figlio del form principale e che però mi permetta di caricare anche un secondo form figlio
Se qualcuno sa darmi un mano mi fa un grandissimo piacere, vanno bene anche dei link..
Grazie a tutti! |
