Your suggestion to fantasy1215's problem was to use a heap-based variable (i.e., pointer) rather than a stack-based one. Exactly how does that help?

I didn't fully understand your question. What is the problem ? You have a button and when you press it, it should display an other modal dialog box and nothing appears, is that your problem ?
What controls are you using on this dialog ? Any non-registered ActiveX controls maybe ? That could be a possible problem.

What you describe is actually the problem I have, and I've found what the problem is.
I have a RichEdit control on my COtherDlg, when I delete delete the RichEdit control, it works fine. While when I add the RichEdit control again, it fails.
But a RichEdit control is not a ActiveX control, right?Help me.

There is this caution in the documentation of CRichEditCtrl. Have you done what it says?
Caution
If you are using a rich edit control in a dialog box (regardless whether your application is SDI, MDI, or dialog-based), you must call AfxInitRichEdit once before the dialog box is displayed. A typical place to call this function is in your program's InitInstance member function. You do not need to call it for each time you display the dialog box, only the first time. You do not have to call AfxInitRichEdit if you are working with CRichEditView.

Hi all,
I have a MFC application which writes some values to a SQL database. It is done iteratively, may be around 5000 times or more. I used a for loop for it, but when it is write around 1000 lines the MFC application(actually the GUI) going to stuck. I have to stop the application to exit it.
I think my question is clear for you.
What should I do to avoid this. Any sufficient way to do this?
I appreciate your help all the time...

Hi..
here i am sending code for that
I had created a table in access
with 3 fields ID1,Nmae,id wher ID is auto number.
Than created DSN name and added a class to application CDB with this new dsn
//CDB m_db;
m_db.Open();
// m_db.MoveLast();
for(int i=1;i<=5000;i++)
{
UpdateData();
CString str;
str.Format("%d",i);
m_db.m_name=str;
m_db.m_id=i;
CString str1;
str1.Format("insert into Table1(name,id) values('%s',%d)",
str,i);
m_db.m_pDatabase->ExecuteSQL(str1);
}
m_db.Close();
}

Thanks,
I'm not much clever, but how about the use of thread here. I found it from one of the article.
And also I found one mistake I've done. Do the SQL connection create and open on that loop. That mean all the time write values to the database, connection is crated and open it. Obviously it is bad.
I appreciate your help all the time...

Can you more explain about your program?
|
|
|
|
|
Just ordinary C++ project that i wrote - with some simple UI ( MFC ).
I really don't see any special issues in my project so i don't know what to explain.

Actually the VS2005 changed the way executable is created for MFC Application. now they also required Manifest file for running of executable. so you need the VC++ redist to be installed on installed computer. or if could research more you could embed that manifest file in the executable and you could deploy your project on target computer without needing to install the VC++ redist, but still you may require the dot net 2.0 enviornment.

Change your project settings to statically link to the MFC DLL
Judy

|
|
|
|
Try that already - its not work.
|
|
|
|
|
Did you rebuild everything after changing the settings? You need to recompile not just relink. You may also need the previous suggestion about a manifest file.

I clean all the project and re-build it all again.
Still not work.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you

I don't know why, but I put the correct link. Anyway search the tread "Study materials for C++/MFC" in thif forum, you may find it.
I've start that tread on 22nd October.
I appreciate your help all the time...

By starting with the basics. On a related note, are you familiar with code development at all?

The following is from MSDN...
//
m_pNewViewClass
CRuntimeClass of the new view to create.
m_pCurrentDoc
The existing document to be associated with the new view.
m_pNewDocTemplate
The document template associated with the creation of a new MDI frame window.
m_pLastView
The original view upon which additional views are modeled, as in the creation of a splitter window's views or the creation of a second view on a document.
m_pCurrentFrame
The frame window upon which additional frame windows are modeled, as in the creation of a second frame window on a document.
//
Here m_pNewViewClass and m_pCurrentDoc is easy to understand.m_pNewViewClass specifies the view class to create a new view. And m_pCurrentDoc gives the document which the new view will attach with.
My question is about the other members.
1/ m_pNewDocTemplate -- how to understand its function and role to create a view?
2/ m_pCurrentFrame -- ?
3/ m_pLastView -- ?
In what situation, the members would be used and for what purpose?
From my side, for example I wanna add another view for a document after default view/doc created by m_pDocTemplate->OpenDocumentFile(NULL/strFile) in an MDI app.
//Demo code
CMainFrame::CreateNewView()//
{
CMyHtmlChildFrame* pHtmlChild=new CMyHtmlChildFrame();//use CRuntimeClass* is also OK
CMDIDemoDoc* pDoc=(CMDIDemoDoc*)(MDIGetActive()- >GetActiveDocument());
ASSERT_VALID(pDoc);
CMultiDocTemplate* pTemplate=(CMultiDocTemplate*)(pDoc- >GetDocTemplate());
ASSERT_VALID(pTemplate);
CCreateContext context;
context.m_pCurrentDoc=pDoc;// use existing document
context.m_pCurrentFrame=pHtmlChild;// new child frame to be upon ??
context.m_pNewViewClass=RUNTIME_CLASS(CMyHtmlView);// new view to be created
context.m_pNewDocTemplate=pTemplate;// use existing document Template??
context.m_pLastView=NULL;// no
if (!pHtmlChild- >LoadFrame(IDI_ICON1,WS_OVERLAPPEDWINDOW ¦FWS_ADDTOTITLE,this,&context))
{
TRACE0("Warning: Couldn 't load frame window!\n");
return -1;
}
//pHtmlChild- >ShowWindow(SW_SHOWMAXIMIZED);
pHtmlChild- >InitialUpdateFrame(pDoc,TRUE);
//pTemplate- >InitialUpdateFrame(pHtmlChild,pDoc,TRUE);
//it worked!
return 0;
}
//
context.m_pCurrentFrame=pHtmlChild;
context.m_pNewDocTemplate=pTemplate;
//
here I can't understand its function in spite that I write it out.
Apprecaited for your kind explanation...
Sam
