Can this class be used without CLR?
Or how can I use WMI without CLR???
I use vc6 with the latest SDK,but there is always a compiler error as bellow:
Deleting intermediate files and output files for project 'Netcfg - Win32 Release'.
--------------------Configuration: Netcfg - Win32 Release--------------------
Compiling...
Netcfg.cpp
C:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\comutil.h(101) : fatal error C1001: INTERNAL COMPILER ERROR
(compiler file 'msc1.cpp', line 1786)
Please choose the Technical Support command on the Visual C++
Help menu, or open the Technical Support help file for more information
Error executing cl.exe.
Netcfg.exe - 1 error(s), 0 warning(s)
what's wrong? How to fix it??
Thank you all here.
Thank you very much.

You've confused the compiler. remove lines of your code until it compiles, then look at the code you removed and see what is wrong.

Hi Everyone!
Can you help me!
Now I'm working in my project. I have a problem With Create a Preview Video with source from Camera. After starting preview 5 minute I want to draw a red rectange on preview.
My idea is Creating two Static. one of them is transparent Static that is always ontop. Then Draw rectange on it.
pls! Can you show me your solution.
Many thanks.

If you're using DirectX, you can create a Filter to draw over the video. You can't put a control over the video to draw on it.

Please help me!
Please show me how to connect to any database (SQL server or Access 2000) by code (not by wizard)
thank you for helping

Use CDatabase class, and its open() function
MSDN description of same is given as
CDatabase m_dbCust;<br />
<br />
m_dbCust.Open( _T( "MYDATASOURCE" ), FALSE,<br />
FALSE, _T( "ODBC;UID=JOES" ),<br />
<br />
m_dbCust.Open( NULL );
refer this

Just to give you an idea, I recently used the following code in one of my projects:
CDatabase m_db;
<br />
try<br />
{<br />
CString sConnect;<br />
sConnect ="DRIVER={Oracle in Ora81RET}; DBQ= MYDATABASE.LOCAL; UID=scott; PWD=tiger; PFC=500";<br />
m_DB.OpenEx(sConnect, CDatabase::noOdbcDialog);<br />
}<br />
catch(CDBException *x)<br />
{<br />
try<br />
{<br />
CString sConnect;<br />
sConnect ="DRIVER={Oracle in OraHome92}; DBQ= MYDATABASE.LOCAL; UID=scott; PWD=tiger; PFC=500";<br />
m_DB.OpenEx(sConnect, CDatabase::noOdbcDialog);<br />
}<br />
catch(CDBException *x)<br />
{<br />
CString szTemp = "Database Connection not responding due to following reason(s):\n\n";<br />
szTemp += x->m_strError;<br />
AfxMessageBox(szTemp, MB_ICONERROR);<br />
exit(1);<br />
}<br />
}
Then, to query the database, you can code like this:
CRecordset cSet(&m_DB);<br />
CString szSomething;<br />
CString szSQL = "SELECT SOMETHING FROM SOMEWHERE"
cSet.Open(CRecordset::forwardOnly, szSQL, CRecordset::readOnly);<br />
while(!cSet.IsEOF())<br />
{<br />
cSet.GetFieldValue((int)0, szSomething);<br />
cSet.MoveNext();<br />
}<br />
cSet.Close();
Hope that helps 
It's better to know some of the questions than all of the answers.
Pravin.

It seems FindFirstFileEx is available only with _WIN32_WINNT >= 0x400.
I am on Windows XP SP2 with visual studio 6 and Feb 2003 PSDK.
The compiler still cannot find FindFirstFileEx and I define _WIN32_WINNT in my stdafx as 0x400. so what is _WIN32_WINNT and when is it >= 0x400.
Although I could get things working by defining _WIN32_WINNT as 0x400, I am worried if thats the right value and if any other definitions arent available due to the value being smaller.
Can someone throw some light on _WIN32_WINNT? Thanks.

These contradict each other. Is it working or not?

Set it to the minimum value required.

I am sorry, I meant it isnt working unless I set it some value. My understanding is that this preprocessor variable is automatically defined for you to the correct number suitable to your current operating system. That is why I am wondering why I have to set it again. It is not clear why I have to set it explicitly and to the minimum value.
Thanks for any clarification.

Which is the correct, normal behavior.

How is the preprocessor going to know the OS of the target machine?

So that you can use functions that are going to be available on the target machine. See here for more.

To let the debugger not generating the error message like:
": identifier was truncated to '255' characters in the debug information"
I add the
#pragma warning(disable: 4786)
int stdafx.h
#if !defined(AFX_STDAFX_H__077D2F6E_ABD0_4A35_9103_5D360AEF8B93__INCLUDED_)
#define AFX_STDAFX_H__077D2F6E_ABD0_4A35_9103_5D360AEF8B93__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
#include <afxwin.h>
#include <afxext.h>
#ifndef _AFX_NO_OLE_SUPPORT

#include "Resource.h"
#endif // !defined(AFX_STDAFX_H__077D2F6E_ABD0_4A35_9103_5D360AEF8B93__INCLUDED_)
But this error message still pops out?

Put it at the very top and pray. I have similar issues.

I move it to the top as you said!The messages finally dispear!
I wonder the causes, On my wild guess: some MFC headers include STL header in stdafx.h, in my previous code stucture the #pragma was put after those MFC headers, so...

Hello everyone! 
OK, I downloaded and installed both of these. I want to make native Windows apps. I ran the register tool in the VC++ Start menu folder, but all I see under "Win32" under "New Project" is console applications... I was trying what the SDK docs told me, it didn't work because I got nothing under "VC++ Directories"... Anybody know what I can do? Thanks!

Express does not support MFC, maybe it doesn't support Win32 either ? I'm sure you can create a Win32 app though, because there's no real framework stuff beyond an include, try to download some Win32 samples and see if they will compile.
Also, it's possible the SDK did not add itself to the include and link directories, if so, you need to do that manually as well.

You're saying that I wasted like 3 GB on it? NOOOOOOOOOOO!!!!!!!!! 
But it can't be! Look:
http://www.thefreecountry.com/compilers/cpp.shtml[^]
That site said:
Microsoft Visual C++ 2005 Express Beta is currently available for download free of charge from Microsoft's site. It allows you to create programs for the .NET framework, and possibly also native Win32 programs (with the help of the separately downloaded Microsoft Windows Platform SDK).
There has to be a way to do this... Anybody else know? Thanks!

MFC, ATL and the Windows headers/libraries are not included with this version. To create Windows programs, you will need to download the Microsoft Windows Server 2003 Platform SDK as well (for the Windows headers and import libraries).
So like I said, you can't do MFC. Looks like you can do Win32, but you need to wire up the right directories yourself, if you installed the PSDK and did not get a good result.

The 2005 beta has MFC, yes. The beta is the same as the final product.
