if you want to go from one dialog to CFormView see
CFrameWnd* pFrame = (CFrameWnd*)AfxGetApp()->m_pMainWnd;<br />
CPictureView* pView = (CPictureView *) pFrame->GetActiveView();
and use from pView->variables or functions

Hello

DirectShow? You can have a look at the AMCap sample that comes with the SDK. You can just connect up the Capture filter -> Sample Grabber filter -> Null Renderer to get a bitmap from the Sample Grabber. There are various articles on DirectShow on CodeProject, just look them up.

dlg.DoModal();
dlg.SetDlgItemText(IDC_EDIT1,str);

Use CMain* pmain=(CMain*)GetParent();
pmain->GetDlgItemText(IDC_EDIT1,str);
etc.....//Main is the class from where you are calling this second dialog
I haven't tried this code on the machine right now but hope it works and helps you

CTeltikDlg* pmain=(CTeltikDlg*)GetParent(); pmain->GetDlgItemText(IDC_EDIT1,str);
// Use this code in the second dialog. Do not forget to include the header file for the first dialog

The most straightforward way is to store the value in your edit control variable of your second dialog. e.g.
Cdlgbox dlg;
dlg.m_sEditControlValue = str;
dlg.DoModal(); And in OnInitDialog() method of your second dialog, you have to set the value into the edit box by calling SetWindowText(...) or another easy way is just to call UpdateData(FALSE).

Hi,
I am trying to make a custom treeview in C++ to display the shell's namespace.
It works great for all folders except physical drives and remote or network folders. I can't get the correct icons for these folders. I am using the following code snippet to load the icons for the specified folder: (Only need to obtain the icon index)
//Retrieve the icon closed for the folder
if(SHGetFileInfo((LPCSTR)lpItemIDList1,0,&fileInfo,sizeof(SHFILEINFO),SHGFI_PIDL|SHGFI_SMALLICON|SHGFI_SYSICONINDEX)==NULL)
{
lpMalloc->Free(lpItemIDList1);
lpEnumIDList->Release();
if(lpSubFolder)
{
lpSubFolder->Release();
}
return FALSE;
}
lpTreeNode->ImageIndex=fileInfo.iIcon;
//Retrieve the icon opened for the folder
if(SHGetFileInfo((LPCSTR)lpItemIDList1,0,&fileInfo,sizeof(SHFILEINFO),SHGFI_OPENICON|SHGFI_PIDL|SHGFI_SMALLICON|SHGFI_SYSICONINDEX)==NULL)
{
lpMalloc->Free(lpItemIDList1);
lpEnumIDList->Release();
if(lpSubFolder)
{
lpSubFolder->Release();
}
return FALSE;
}
lpTreeNode->SelectedIndex=fileInfo.iIcon;
The pointer lpItemIDList1 points to a piddle that contains the absolute location of the specified folder. (Relative to the root aka desktop folder)
I am only trying to display folders.
Thanks

I am trying to read from a text file and output the data to a CSV file. Can anybody help me with this please?
Cheers Phil

Are you using MFC? Then go though the class CStdioFile, which gives easy functions to read and write text files.

I'm using Visual C++. Would it work in the same way?

CSplitterWnd m_wndsplitter;
return m_wndsplitter.Create(this,2,2,CSize(10,10),pContext,WS_CHILD|WS_VISIBLE|WS_HSCROLL|WS_VSCROLL|SPLS_DYNAMIC_SPLIT,AFX_IDW_PANE_FIRST);

What's that return written in the mid of your code.
Have you derived classes from CView ?

Listen Ashish.
What I told you yesterday was that you would need to derive classes from CView and then use CreateStatic(.....)
For example I am providing a snippet of code for splitting a window in shape of
////////////////////////////////
-------------||-----------------
------1-View-||--------2 View--
-------------||-----------------
-------------||-------------------
=================================
3 View
/////////////////////////////////
m_wndSplitter1.CreateStatic(this,2,1);
m_wndSplitter1.CreateView(1,0,RUNTIME_CLASS(COneView),CSize(200,200),pContext);
m_wndSplitter2.CreateStatic(&m_wndSplitter1,1,2);
m_wndSplitter2.CreateView(0,0,RUNTIME_CLASS(CTreeDeriv),CSize(200,200),pContext);
m_wndSplitter2.CreateView(0,1,RUNTIME_CLASS(CTwoView),CSize(200,400),pContext);
return TRUE;
///////////////////////////////////
here COneView and CTwoView were the classes that were derived from CView.

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
int n_id = AFX_IDW_PANE_FIRST;
if (!m_splitwnd.CreateStatic(this, 1, 2, WS_CHILD|WS_VISIBLE|WS_BORDER, n_id))
{
return FALSE;
}
if (!m_splitwnd.CreateView(0, 0, RUNTIME_CLASS(CView1),CSize(0, 0), pContext) ||
!m_splitwnd.CreateView(0, 1, RUNTIME_CLASS(CView2), CSize(0, 0), pContext))
{
m_splitwnd.DestroyWindow();
return FALSE;
}
m_splitwnd.SetColumnInfo(0, 300, 50);
return TRUE;
}
My Code is runing. You can try.
// with CView1/2 your View
If one of view is CFormView, you check setting Dialog of FormView, Style is Child.
.: Your success is also mine :.
