Am about to embark on the process of upgrading our companies development systems from VC 6.0 to Visual Studio .Net C++. Am a bit confused why .Net C++ is only $110 a copy from MS, but .Net Professional is $700. Other than support for C# etc, are there any significant differences? Has anybody else had problems with such a change-over?

Since you already use Visual Studio v6, you can upgrade to Visual Studio .NET 2003 Professional for $550. It also comes with Visual Basic .NET and J#, if you need those. You get Windows Server 2003 Standard Edition. You get SQL Server 2000 Developer Edition. You get Microsoft Visual Studio Tools for Microsoft Office.

Hello. Does anyone know how to code a Auto-Entry CDataCombo. CDataCombo is an Active X control. I created a auto-completing CCombobox and made my CDataCombo inherit from it. However, it does not behave the same way. For example when I invoke ShowDropDown(), my CDataCombo does not respond. Any thoughts, please help.

If the constant MECHANICAL was defined in the main class, I remove a menu item in InitInstance(). Now at the start of the application, the menu does get deleted. But when I go to File->New, the deleted menu reappears. How do I stop it from re-appearing? Thanks!
//MainApp
#define MECHANICAL
//In main app in function InitInstance()
#ifdef MECHANICAL
pMainFrame->OnChangeFileMenu();
#endif
void CMainFrame::OnChangeFileMenu()
{
CWnd* pMain = AfxGetMainWnd();
// Get the menu from the application window.
CMenu* mmenu = pMain->GetMenu();
// Look for "Tools" menu.
int pos = FindMenuItem(mmenu, &Tools");
if (pos > -1)
mmenu->DeleteMenu(pos, MF_BYPOSITION);
pMain->DrawMenuBar();
}
int CMainFrame::FindMenuItem(CMenu *menu, LPCTSTR menustr)
{
ASSERT(menu);
ASSERT(::IsMenu(menu->GetSafeHmenu()));
int count = menu->GetMenuItemCount();
for (int i = 0; i < count; i++)
{
CString str;
if (menu->GetMenuString(i, str, MF_BYPOSITION) &&
(strcmp(str, menustr) == 0))
return i;
}
return -1;
}

What am I trying to do....
Using VC++ 6 and MFC
The application does several things. It receives 3 threads of information via a TCP/IP connection. It also monitors a directory for new files. All of the data is processed and logged as it is received. A worker thread handles the multiple threads.
A dialog box interface will be used to display a summary of the information. The dialog needs to be a property sheet (tab dialog) with a summary page listing all data from all sources. The other tabs are more detailed breakdowns of each type of data.
My problem is...
So far, I have been using a list control on each tab for the data display. However, I can't figure out how to get the data to display in the list.
If I create a list box on the main dialog, I can use AddString or InsertItem just fine. But when I try to do the same with my property pages it doesn't work.
Please help.

This seems very odd to me. Even though CPropertySheet is not derived from CDialog, it is managed in a similar fashion. I would suggest deriving CTryproppageDlg from CPropertySheet. Add a CPropertyPage member variable for each tab required. In CTryproppageDlg's constructor, call AddPage() for each of those member variables. In each of the tab's OnInitDialog() method, call CListCtrl::InsertColumn(). Then populate the controls as necessary. Thus should be a much cleaner approach.

I'm trying to set the height of a combobox (as opposed to the height of the dropdown list), but I just can't seem to find any quick fix for it on the net.
Is there a quick fix?

Yes I did. But the thing is that comboboxes are bastardizations, and doesn't deserve to be called windows. You can tell it's an OLD OLD hack from the Win 3.x-era (probably 2.x), that's been kept alive due to legacy reasons.
I found the workaround after a good nights sleep. Apparently googling becomes increasingly difficult as you become more tired.  Anyway, the solution to the problem (I also found this in the MSDN docs this morning): SetItemHeight(-1, nYourHeight);
Henceforth, I will call this control: "ugly bag of mostly hacks".

Hi Guys I have been banging my head against the wall for some time.Please Help...
I have downloaded an example in C#.NET and have made some conversion that have worked
in my C++.NET winform application. Does anyone have any ideas?
The last line does not work.......
// get the collection of sheets in the workbook
//C# example
// Excel.Sheets sheets = theWorkbook.Worksheets;
// This conversion works
Interop::Excel::Sheets *sheets = theWorkbook->Worksheets;
//C# example
// Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);
// This does not work..it is looking for a
// error C2664: 'Interop::Excel::Sheets::get_Item' : cannot convert parameter 1 from 'int'
// to 'System::Object __gc *'
Interop::Excel::Worksheet *worksheet = (Interop::Excel::Worksheet*)sheets->get_Item(1);

I'm trying to find a way to detect the type of bus connection a video card has, programatically of course. Valid types being PCI, AGP, and PCI-Express. And of course that bus's speed would be nice too, like 8x, 16x, etc. I've been searching everywhere and tried many things, including WMI which doesn't have that information.
Any ideas are much appreciated!

Hi,
For quite long time now I've been trying to get the Crypto++ (www.cryptopp.com) library working with a simple MFC Dialog Based application.
The strange thing is that a Win32 console application links and works fine with the same settings :-|
Here are the errors I'm getting:

Maybe there's something wrong with my configuration? Or with my VC++ instalation? Some library is still missing?
I was suggested that there could be something wrong with Calling / Naming convention but changing Calling convention didn't help
I've tried switching many options in Project -> Setting but neither helped.
I'm really in need of help
If needed I can gladly give more code snippets...
Best regards,
Maciej Zieba

Software Development Kit vs. Application Programming Interface. An SDK can contain many APIs.

You seem to have a fundamental confusion as to what an SDK is and what an API is. While a difference exists, depending on your perspective, there's nary a reason to know. What exactly is it that you are trying to do.

i had used the api to know the text of active window on the computer.For that i got the api "GetWindowText( , , )" from api text viewer.
i tried to use in the visual c code. but the problem is that there is the Cwnd function with same name but it take two argument.the first argument which is the activewindow handle is not present tell me what to do
more description is below.
result=GetWindowText(m_hhandle1,str1,512);//this is api i had seen on api textviewer comes with visual studio. i want to use API had the three parameter
//1.The first handler form above API
//2. buffer to store the windowname
//3.length of buffer
//but i takes two arg not three bcos it consider it a fucntion of CWnd not API. what to.

CWnd encapsulate the hwnd of the Window; so when using CWnd::GetWindowText( ... ), you actually use the hwnd of the current CWnd ( this ).
if you want to use the ::GetWindowText, you will need to get the HANDLE of the CWnd you want.

i had got that handle through the GetForegroundWindow API. but problem is that this Cwnd functin GetWindowText take two argument it does not take the handle of window as parameter as GetWindowText API does.
i hope u had understood the problem that i dont want to use Cwnd function bcos it work for the current window only not all window handle got through the api Getforegroundwindow.i want the enabling of api function not cwnd func.

if you want to use API function, you need to use the :: prefix for the function :
::GetWindowText( ... );

Try:
result = ::GetWindowText(m_hhandle1, str1, 512);
