You need to provide some more information on the problem. Is that the exact message that you see, and which DLL is it missing?

Hi all,
i make a nice CMyFileDialog derived from CFileDialog that works fine for my need, but i need just one function for my Dialog and this is when a user select some file in a list to catch this event, something like:
"OnItemChange", is this possible, something like CListCtrl function itemchange??? If yes can someone give me a suggestion how to do this?

Best Regards
bosfan

Hi,
thanks for answer, but in this example works only if you know the id of a list control, e.g. my own list controls on a dialog where i give the id to the ctrl? Right?

Best Regards

Hello,

I found a example with OnNotify() and i use this as reference:
ImageImport Filedialog

Many thanks

How to associate an index value with the cstring objects in a CStringArray in MFC.?

thanks for answer Smile | :)

Hi,

I am using CStringArray to store images in sequence. I need one help. I will load an image on the canvas area, then I'll apply an effect on that image. Then I'll store that image into CStringArray. I'll store the images in sequence as I'll apply an effect one after one. Now to undo the last applied effect I'll get the last image and load the same into canvas Area.

Isuue is that I am using check boxes to apply effects on images. If user has applied effect 'A', then 'B', then 'C', and so on. Now if user has unchecked the box with effect 'B', then It should load the image which was before applying effect 'B'. I want to store and know the state of the image before applying the effect and load that image only.

Anybody have any idea how to do this. I would appreciate if anyone can suggest me a better solution than what I am using.

Regards,
Mbatra

map<int,CString>,

use this to create association between index and CString object.

Child dialog shadow remains

You may find that CByteArray[^] would be a better choice.

Hi, this is my first post.

Work flow is like this:
i open child dialog from a dialog( which is launched from a toolbar of a window) after editing i close the child dialog, after closing child dialog shadow is retained on window but not on the parent dialog. Later when i close the parent dialog the child dialog shadow disappears.
(issue exist only when i edit in child dialog)

Thanks a lot,
Shivaraj

Thanks for reply, I have seen same design patterns(using child dialog)in the same application but there is no issue there. I compared the code, am not finding any difference in RePainting aspects.

here i have sample code..

Below used OnModifyview dialog is child dialog of a dialog.

void CSelectColumnViewDlg::OnModifyview()
{
int iIndex = m_ctrlColumnViewList.GetCurSel();
if (iIndex < 0)
return;
double dViewId = m_ctrlColumnViewList.GetItemDataDouble(iIndex);
if (dViewId == 0.0)
return;
CWaitCursor wait;
CComPtr pDispColumnView;
CComPtr pManager;
pManager.CoCreateInstance(CLSID_TrackingDataManager);
if (pManager)
pManager->GetColumnView(dViewId, &pDispColumnView);
CComQIPtr pColumnView(pDispColumnView);
if (pColumnView == NULL)
return;
CModifyColumnViewDlg dlg;
dlg.SetColumnView(pColumnView);
dlg.SetType(m_lSolution, m_lListType);
dlg.SetTrackGroupCd(m_dTrackGroupCd);
std::set* pExistingNames = GetExistingNames(iIndex);
dlg.SetExistingNames(pExistingNames);

C++

if (dlg.DoModal() == IDOK)
{	//Issue exist only when i edit in child dialog & click OK (above child dialog OK)	

HWND hWndAncestor = ::GetAncestor(GetSafeHwnd(), GA_ROOT);
 
//hWndAncestor->Invalidate(); //not working
//InvalidateRect(hWndAncestor, NULL, TRUE); //not working
//::RedrawWindow(hWndAncestor,NULL,NULL,RDW_INVALIDATE); //not working
//::UpdateWindow(hWndAncestor); //not working

 
m_ctrlColumnViewList.DeleteString(iIndex);
 
CComBSTR bstrName;
pColumnView->get_Name(&bstrName);
int iIndex = m_ctrlColumnViewList.AddString(CString(bstrName));
m_ctrlColumnViewList.SetItemDataDouble(iIndex, dViewId);
m_ctrlColumnViewList.SetCurSel(iIndex);
 
//Invalidate(); //not working
//RedrawWindow();	//not working

}

if (pExistingNames)
delete pExistingNames;
Invalidate();
//OnPaint(); //not working
//RedrawWindow();// not working
}

Are you using any drawing in the parent dialog that launched the CModifyColumnViewDlg?
If you don't have any OnPaint handler for the parent dialog, Invalidate is not required.
Otherwise use UpdateWindow()

Not true, http://www.codeproject.com/Messages/4389343/Child-dialog-shadow-remains.aspx[^] is your first post.
I don't know why you have raised this question again, I have explained three times why this happens. You cannot repaint your main window until the first dialog returns from the call to DoModal(). And, as I also said earlier this is not a good design; modal dialogs should not need to call other dialogs to complete their operations, but should be completely self-contained.

One of these days I'm going to think of a really clever signature.

While I have library function from C, C++ and MFC, which one I should use.

Say for Example, fOpen like APIs from C, IoStream like supplied function from C++ or MFC's CFile supplied one. Which one is best choice when want to to a heavy text processing [Searching for some tags in a 2-3 MB file, preparing a report].
