I have a COM DLL built with VC++6 and it has dialog resources using activex controls such as MsFlexGrid and CTreeCtrl etc.
I have two main applications(AppSimple and AppWithLotOfDlgResources) that can use this dll.
When I use AppSimple to call this Dll, it works fine both in Debug and Release modes.
The problem is when I use AppWithLotOfDlgResources application as the calling program, I am getting "Unsupported operation" only in RELEASE build.
Q. Is there some kind of a conflict in resources between the DLL and the AppWithLotOfDlgResources ?
Please help
Thanks

When I do stuff like:
POSITION pos = pDoc->GetFirstViewPosition();
while (pos!=NULL)
{
CView* pView = pDoc->GetNextView(pos);
I dont have the second view created or instantiated. Yet the code still works. Is this weird? Does the doc automatically know which views it has even if I dont do:
pChild = (CMDIChildWnd*) pTemplate->CreateNewFrame(pDoc, NULL );
if( pChild == NULL ) return FALSE;
pChild->MDIActivate();
pTemplate->InitialUpdateFrame( pChild, pDoc);
on it? (I do the createframe when I switch views). Am I creating the view here? I've used the first snippet even when the second snippet has not been executed..and it works
Appreciate your help,

here's my OPENFILENAME struct:
char szFileNames[(MAX_PATH+1)*1000+1];
ofn.lStructSize = sizeof(ofn);
ofn.hwndOwner = ghWnd;
ofn.hInstance = ghInstance;
ofn.lpstrFilter = "All Files (*.*)\0*.*\0";;
ofn.lpstrCustomFilter = NULL;
ofn.nMaxCustFilter = NULL;
ofn.nFilterIndex = 1;
ofn.lpstrFile = szFileNames;
ofn.nMaxFile = (MAX_PATH+1)*1000+1;
ofn.lpstrFileTitle = NULL;
ofn.nMaxFileTitle = NULL;
ofn.lpstrInitialDir = "C:\\";
ofn.lpstrTitle = "Open File(s)";
ofn.Flags = OFN_ENABLESIZING | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_PATHMUSTEXIST | OFN_ALLOWMULTISELECT | OFN_EXPLORER | OFN_NODEREFERENCELINKS | OFN_NONETWORKBUTTON;
ofn.nFileOffset = NULL;
ofn.nFileExtension = NULL;
ofn.lpstrDefExt = "*.*";
ofn.lCustData = NULL;
ofn.lpfnHook = NULL;
ofn.lpTemplateName = NULL;
ghWnd is a valid handle to my main window and ghInstance is also a valid handle to my apps memory block
When i run the GetOpenFileName function it returns false, and a call to GetLastError returns "invalid parameter", what am i doing wrong?
Thanks

Hi,
I am using VC++ 7.0 and am trying to load an icon, which I have as one of my resources, into my button. The button is created dynamically.
Here is the code that I have:
button->Create("SMS", WS_CHILD | WS_VISIBLE | BS_FLAT | BS_ICON,
CRect(0,0,0,0), &m_wndStatusBar, IDC_BUTTON_STATUS_BAR);
button->SetIcon(::LoadIcon(NULL, MAKEINTRESOURCE(IDI_ICON1) ) );
This does not seem to work. I know it worked in VC++ 6.0.
Can anyone help me out here?
Thanking you in anticipation
Rui

m_ctrlViewList.SetIcon(AfxGetApp()->LoadIcon(IDI_VIEW_LIST));
which m_ctrlViewList is a CButton, more...the icon size is in 32 pixel
==================
BTW, if you want set a other size of icon, like 16*16 size, you can code like this..
//.h file
CImageList m_ButtonImages;
//.cpp file
m_ButtonImages.Create(16,16,ILC_COLOR32 ,2,2); //create you icon list
m_ButtonImages.Add(AfxGetApp()->LoadIcon(IDI_VIEW_ICON ));
m_ButtonImages.Add(AfxGetApp()->LoadIcon(IDI_VIEW_LIST ));
m_ctrlViewIcon.SetIcon( m_ButtonImages.ExtractIcon(0));
m_ctrlViewList.SetIcon(m_ButtonImages.ExtractIcon(1));

THis is what I want to do: clear a listbox in view2, and repopulate it.
POSITION pos = pDoc->GetFirstViewPosition();
while (pos!=NULL)
{
CView* pView = pDoc->GetNextView(pos);
ASSERT_VALID(pView);
pView->m_list1.DeleteAllItems();
pView->PostMessage(WM_COMMAND, IDC_BUTTONHIDEV2,0);
}
THis line gives an error error C2039: 'm_list1' : is not a member of 'CView'
pView->m_list1.DeleteAllItems();
My View class is called TView1. How do I make this work?
Appreciate your help,

TView1* pView = (TView1 *)(pDoc->GetNextView(pos)); or if you like the C++ cast syntax:
TView1* pView = static_cast<TView1 *>(pDoc->GetNextView(pos));

Actually the class that has the listbox is called CDlgList.
With great trepidation I did the cast as
CDlgList* pView =
and it worked!
thank you,

try casting to ur own view
{
CYourView* pView = (CYourView*)pDoc->GetNextView(pos);
ASSERT_VALID(pView);
pView->m_list1.DeleteAllItems();
pView->PostMessage(WM_COMMAND, IDC_BUTTONHIDEV2,0);
}

I want to search the memory when an application is running for a string value and alter it, but i have no idea on how to start. I realise i'd have to look for the WORDs the string is composed off but i dont know how to access the memory, let alone search it. I am trying to make a trainer program for a game. Can anyone help me on this?
Thanks

No, that's cheating !
BTW, I don't know how to do this, so if anyone can tell us !

Try using DebugActiveProcess to atach to the process.
After this call your application will be like a debugger and will be able to stop execution and inspect it's virtual memory.
There is a complete section in the platform SDK dedicated to the debugging API in windows.

How do you catch a connection error in CSocket?? It doesn't seem possible..
CSocket sSocket;
sSocket.Create();
int iCon = sSocket.Connect("some.dns.com", 21);
if(iCon != 0)
MessageBox("Error Connecting");
or
if(iCon == SOCKET_ERROR)
MessageBox("Error Connecting");
Even if the address doesn't exist it will allways return a 0. (success)
I derived my own CSocket class and and over rode OnConnect(int nErrorCode) so that if it returns a error I post the message and if it doesn't error run a function.. it never returns anything..
The only reason I am using CSocket is because I need to use CSocketFile and CArchive..
Any ideas?? Or is this how it's supposed to work?

Here is internal MFC code executed by the Create() call :
BOOL CAsyncSocket::Create(UINT nSocketPort, int nSocketType,
long lEvent, LPCTSTR lpszSocketAddress)
{
if (Socket(nSocketType, lEvent))
{
if (Bind(nSocketPort,lpszSocketAddress))
return TRUE;
int nResult = GetLastError();
Close();
WSASetLastError(nResult);
}
return FALSE;
}
And you still wonder why it always returns 0. Come on....
From this code, it's also clear you can call either ::GetLastError() or ::WSAGetLastError() to get the actual error.
How low can you go ? (MS retrofuck)

Hi All,
I'm trying to implement a message window, like the one in Visual Studio, without the tabs, though. I've got a CDialogBar member in my main frame class, with an embedded rich edit control. How do I send text to a rich edt control programmatically? I was using a list control, but didn't like the way this worked, since it didn't give many formatting options. I thought about using a regular edit control, but then I couldn't do fancy formatting either.
Thanks
Aaron

AFAIK, you can call SetWindowText on the rich edit control, but this is probably inefficient. Try looking up the CRichEditCtrl member StreamIn, or the windows message EM_STREAMIN.

StreamIn seems to work OK. Thanks

I'm working on a little security program to ensure that invalid CD's do not get inserted into our SOE machines, and to enable this I'm building a little program to manage adding a link to the users start menu.
What I need to know is there an easy way to detect if there is a CD ROM Inserted.
I've been playing with CreateFile for the purpose which is fine, to ascertain that the actual CD that is currently in the Drive is invalid, BUT if there is no disk at all, then a No Disk in CD warning is displayed by the operating system.
Is there a way to disable the Warning(temporarily) or a better way to check for the prescence of a disk?
Thanks for any help.
