Re: problems in creating file dialog in tab control
Hi AliR,
I am sorry. the code is like this:
(1) create the tab control
hwndTabCtrl=CreateWindow
(WC_TABCONTROL,"",WS_CHILD|WS_CLIPSIBLINGS|WS_VISIBLE,0,0,rcClient.right,rcClient.bottom,hwndParent,NULL,g_hinst,NULL);
if(hwndTabCtrl==NULL)
AfxMessageBox("can't create tab control window");
(2) create three dialogs
pDialog[0]=new CPartDlg();
pDialog[0]->Create(IDD_DIALOG_FOR_PART,NULL);
pDialog[1]=new CMachineDlg();
pDialog[1]->Create(IDD_DIALOG_FOR_MACHINE,NULL);
pDialog[2]=new CProcessDlg();
pDialog[2]->Create(IDD_DIALOG_FOR_PROCESS,NULL);
(3) insert items to Tab control
m_tcitem.mask=TCIF_TEXT|TCIF_IMAGE;
m_tcitem.iImage=-1;
for(int i=0;i<TAB_PAGE_COUNT;i++)
{
m_tcitem.pszText=g_tabName[i];
if(TabCtrl_InsertItem(hwndTabCtrl,i,&m_tcitem)==-1)
{
AfxMessageBox("can't insert");
DestroyWindow(hwndTabCtrl);
}
(4)set the display area for tab control
DeferWindowPos(hdwp,hwndTabCtrl,NULL,rcClient.left,rcClient.top+100,(rcClien
t.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,0);
EndDeferWindowPos(hdwp);
(5) select the page and show the window
int i_nPage=TabCtrl_GetCurSel(hwndTabCtrl);
pDialog[i_nPage]->ShowWindow(i_nPage);
(this maybe a little different)
the big problem here is I always get the value of i_nPage=0, when I
select the second page, this value is still zero. Does it mean that I
have to process the message TCN_SELCHANGE? I remeber from MSDN saying
that can use the macro TabCtrl_GetCurSel() replace sending
TCN_SELCHANGE message explicitly? I don't know why. thanks again.

Thanks,AliR. I modify my codes according to your suggestion. but there
still the same problem.What I want is like this: when I select the
first page,one dialog is shown up(not automatically) and when I select
the second page the other dialog is up. because I use DLL, it is not
easy to process the message TCN_SELCHANGE. i use the macro
TabCtrl_GetCurSel(), but I don't know why the return value is always
zero. Please help me!
The codes are like:
//create tab control handler
hwndTabCtrl=CreateWindow(WC_TABCONTROL,"",
WS_CHILD|WS_CLIPSIBLINGS|WS_VISIBLE,0,0,rcClient.right,rcClient.bottom,hwndP
arent,NULL,g_hinst,NULL);
if(hwndTabCtrl==NULL)
AfxMessageBox("can't create tab control window");
//create dialog for file
pDialog[0]=new CPartDlg();
pDialog[0]->Create(IDD_DIALOG_FOR_PART,NULL);
//create dialog for machine
// CMachineDlg *pMachineDlg;
pDialog[1]=new CMachineDlg();
pDialog[1]->Create(IDD_DIALOG_FOR_MACHINE,NULL);
//CREATE dialog for process
// CProcessDlg *pProcessDlg;
pDialog[2]=new CProcessDlg();
pDialog[2]->Create(IDD_DIALOG_FOR_PROCESS,NULL);
//fill tab control's information
m_tcitem.mask=TCIF_TEXT|TCIF_IMAGE;
m_tcitem.iImage=-1;
for(int i=0;i<TAB_PAGE_COUNT;i++)
{
m_tcitem.pszText=g_tabName[i];
if(TabCtrl_InsertItem(hwndTabCtrl,i,&m_tcitem)==-1)
{
AfxMessageBox("can't insert");
DestroyWindow(hwndTabCtrl);
}
}
TabCtrl_AdjustRect(hwndTabCtrl,FALSE,&rcClient);
TabCtrl_GetItemRect(hwndTabCtrl,0,&rcTab); //Get the tab page
dimension
hdwp=BeginDeferWindowPos(1);
DeferWindowPos(hdwp,hwndTabCtrl,NULL,rcClient.left,rcClient.top+100,(rcClien
t.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,0);
EndDeferWindowPos(hdwp);
int i_nPage=TabCtrl_GetCurSel(hwndTabCtrl);
if(pDialog[i_nPage]->m_hWnd)
pDialog[i_nPage]->ShowWindow(SW_HIDE);
for(int j=0;j<3;j++)
{
pDialog[j]->SetWindowPos(&pDialog[j]->wndTop,
rcClient.left,rcClient.top+100+rcTab.bottom-rcTab.top,
(rcClient.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,SWP_HIDEWI
NDOW);
}
pDialog[i_nPage]->SetWindowPos(&pDialog[j]->wndTop,
rcClient.left,rcClient.top+100+rcTab.bottom-rcTab.top,
(rcClient.right-rcClient.left)/4,(rcClient.bottom-rcClient.top)/3,SWP_SHOWWI
NDOW);
pDialog[i_nPage]->ShowWindow(SW_SHOW);
Thanks

In order for one dialog to be created as part of another window the
Dialog
must have the WS_CHILD style, and by default CFileDialog has the
WS_POPUP
style. There are ways around that, you can override the dialog template
of
the file dialog and telling CFileDialog to load that instead.
http://www.codeproject.com/dialog/xfiledialog.asp
The other thing is that you will have to use CFileDialog::Create method
instead of DoModal.

Hi,I am creating a tab control and want to pop up a file dialog when
clicking one tab page. but now, the file dialog was shown up at the
same time with tab control, not after selecting one page. Could some
guys help me? Thanks
