C++ will not "include" (map) object as long as it's not referenced....
So if you declare class:
class CBrian {
CBrian();
virtual ~CBrian();
void X();
}
It will compile just fine even tho CBrian() and ~CBrian() has no body.
As soon as you declare: CBrain var; compiler will try to map space(frame) for all object members and functions. C++ at that stage will notice all the missing members.

Argh!
Thank you!
I made a body for all my "unresolved external symbols" and it works!

DWORD dwCb = sizeof(RASENTRYNAME);
DWORD dwEntries = 0;
RASENTRYNAME lpRasEntryName[20];
lpRasEntryName[0].dwSize = sizeof(RASENTRYNAME);
RasEnumEntries(NULL,NULL,lpRasEntryName,&dwCb,&dwEntries);
This is the code. The problem is that RasEnumEntries returns 610 which is ERROR_BUFFER_INVALID only on Windows98. The code works perfectly on win2000. What is the problem, I need this problem to be solved as soon as possible
Please help me

Change to:
DWORD dwCb = sizeof(RASENTRYNAME);<br />
DWORD dwEntries = 0;<br />
RASENTRYNAME lpRasEntryName[20];<br />
<br />
ZeroMemory(lpRasEntryName, sizeof(lpRasEntryName));<br />
<br />
lpRasEntryName[0].dwSize = sizeof(RASENTRYNAME);<br />
RasEnumEntries(NULL,NULL,lpRasEntryName,&dwCb,&dwEntries);
I'm not sure about it

Try:
DWORD dwCb = 20 * sizeof(RASENTRYNAME);

I think you have to do this for all 20 structures in your array. (Note the word "think" - something rings a bell that you have to do this, but I can't remember for certain!).
Hope this helps!

Well, the problem is that this code works everywhere else than on Win98 OS and I don't know why.
even when I took a piece of code from the www 610 error appears.

I had this same problem a couple years ago. In my case the problem showed up when I complied under Studio.Net with win2000 and used the program on Win98. Did not have the problem when I complied under Studio 6. I ended up creating a DLL with all the RAS operations in it complied with Studio 6 and used it in the rest of the application complied with Studio.Net. I spent a lot of time looking at Ras header files and it was a nightmare.

AOA!
last night as i was trying to do one of my Assignments i tried to open a form using my Class inherted from CFormView!
the problem is that i was able to show the form as i want but as i close this window using the CWnd::DestroyWindow() i get an Assert Failure!
the Code i am using to initialize the window is as follows:
//defined in MyClass.h;
CMyClass Form;
CMyMainView::OnInitialUpdate()
{
CView::OnInitialUpdate();
CRect Rect;
GetClientRect(Rect);
Form.Create(NULL,"NewForm",WS_VISIBLE|WS_BORDER|WS_CHILD,Rect,this,1234,NULL);
}
And to Destroy the Window
CMyMainView::OnFileNew()
{
Form.DestroyWindow();
}
i cant understand y i get the assert failure when i click the new button on the toolbar!
the Assert Failure Message i get is as follows:
Debug Assertion Failed!
Program:E:\Chummi.exe
File:dbgheap.c
Line:1101
Expression:_CrtIsValideHeapPointer(pUserData)
//bla bla bla

You must allocate Form dinamically because CView::PostNcDestroy contains delete this  . Make it CMyClass *pForm.

Hiya I have an MFC app that writes data to my SQL database. The columns lenghts are set to 30. But when I open my SQL database to view the contents, I can only see the first 15 chars of each column..
How do I get the SQL database to display the full columns lenghts when it is opened??
Thanks,
grahamoj.

What do you mean by "the SQL database"?

I meant that I have SQL loaded on my machine for doing database stuff..
What I do is write the info to the database and then using Enterprise Manager, go in to the table to view it. All of the string is in the column. I can see it when I expand the column.
What I want to be able to do is when I open the table in Enterprise Manager, I want the column already expanded to the full lenght of the string...
Any ideas,
grahamoj

hi ppl.
i am making an Internet Explorer toolbar plugin using the sample Kbbar.
In it i want to load a dialog from resources. but it resulted in Debug assertion failure.
Upon debugging in depth i came to find out that AfxGetResourceHandle() was the reason, as call to this function or a call to MAKEINTRESOURCE macro resulted in the Debug Assertion failure problem. plz help me in that.
here is the portion of the code :
m_pMsgDlg = new CMsgDlg(this); /* m_pMsgDlg is a pointer of CMyDialog: public CDialog */
if (m_pMsgDlg->Create(IDD_MSGDLG, tempPtr) == FALSE)
{
MessageBox("no dialog");
}
plz plz help me.

Try this:
HINSTANCE hsav= AfxGetResourceHandle();
AfxSetResourceHandle(theApp->m_hInstance);
m_pMsgDlg = new CMsgDlg(this);
if (m_pMsgDlg->Create(IDD_MSGDLG, tempPtr) == FALSE)
{
MessageBox("no dialog");
}
AfxSetResourceHandle(hsav);

Don't use AfxGetApp() but the singleton theApp, The one and only.
[EDIT]
But first make sure that you wrote AFX_MANAGE_STATE(AfxGetStaticModuleState()); at the beginning of your function.

multiple Documents in SDI applications.
Hi,
I have an application that is mainly a SDI form based app. There is no sence in opening more than one document in a time. I use a technique to switch between 4 different views based on the state of the app and again, there is no need to see two of the views at the same time.
I have a few ScrollView derived Ctrls on the FormView where I already had problems that mouseactivation on the ScrollView derived class will send a SetActiveView to the mainFrame. This results in unexpected program behavoir (mostly program crashes later on). For these problems I already have a workaround.
Yesterday I tried to include debugging capablities using the CEditLog class with a CEditView ctrl in a CControlBar. Again I had the problem that upon activation the CeditView Window sends SetActiveView calls to the MainFrame and additionally will call CDocument::SetModified (). I choosed the EditView since I wanted to use the search / serialize capabilities, but the CEditView needs a Document, so I gave an empty CDocument to the CEditView. But this only leads to additional problems. Terminating the application while the focus is on the ControlBar leads to crashes since the View has changed and so on.
I don't really want to switch to an MDI application, only to support edit capabilities or better a second CView derived window.
Does anybody have similar experiences with something like this? Must I switch to an MDI app?
Thanks in advance
Dirk

hello,
i'm working with ListCtrl in VC7.
i'm trying to detect if in "MouseMove" event the Left Button mouse is Down(Thx Thomas George & Joel Lucsy ) but i have a little problem
i do :
<br />
BOOL ClistctrlView::PreTranslateMessage(MSG* pMsg)<br />
{<br />
<br />
if (pMsg->Message == WM_LBUTTONDOWN)<br />
{<br />
ButtonDown = TRUE;<br />
}<br />
if (pMsg->Message == WM_LBUTTONUP)<br />
{<br />
ButtonDown = FALSE;<br />
}<br />
if (pMsg->Message == WM_MOUSEMOVE)<br />
{<br />
if (ButtonDown == TRUE)<br />
{<br />
AfxMessageBox("goooood");<br />
}<br />
<br />
if (pMsg->Wparam & MK_LBUTTON)<br />
{<br />
AfxMessageBox("goooood");<br />
}<br />
<br />
}<br />
return CListView::PreTranslateMessage(pMsg);<br />
}
I can Detect WM_LBUTTONDOWN, LBUTTONUP, MOUSEMOVE but if i want to detect in MouseMove if The left button is down it doesn't work !!!
And if i try this code in "CView" object, it works great !
any ideas ??
Thx in advance

Maybe you should not do (pMsg->Message == WM_MOUSEMOVE) but something like (pMsg->Message & WM_MOUSEMOVE). Because if you have both the button down and the mouse moving, your Message will be equal to (WM_MOUSEMOVE |WM_LBUTTONDOWN) which is different from WM_MOUSEMOVE alone. Je suis clair ou pas ?

Let's say I have a main window and 3 child windows.I want when minimizing the main window the child windows to remain on the desktop. I'm trying with SetParent() function but I'm missing something...what is it?
|
|
|
|

You may make the parent of the childs the desktop window on the child creation.
For example if a child is a modeless dialog, you create it like this
m_MyDlg.Create(IDD_MYDIALOG, GetDesktopWindow());
There is many problems with this method, but I think they may be overcomed.
