I have a very primitive question on C++. If I want include a library I use #include say, #include , iostream header file all I/O functions are declared. But Including a Standard C++ header does not introduce any library names into the current namespace. For that we have to use using namespace std; What does this mean? Does it mean in namespace std all the functions in standard library files are defined and that's why we need that?

Hi, I was trying to build an ATL VC++ program in .net 2003 and I keep getting LNK 2019 errors. In the MSDN I searched for that error and I found the following. Can anybody tell me where I can find _check_commonlanguageruntime_version function and where to put that? In Visual C++ .NET 2003, this error will be generated when /clr is used and the CRT is not linked into your executable. Any object code generated by the compiler that is not built with /clr:initialAppDomain contains a reference to the _check_commonlanguageruntime_version function, which is defined in the C Runtime Library (CRT). This function provides for an error message if your application is run on version 1 of the runtime. Code generated by the current compiler is not compatible with version 1 of the common language runtime. So, if you compile without the CRT in Visual C++ .NET 2003, you should include a definition of the _check_commonlanguageruntime_version function in your code. As an alternative to using the _check_commonlanguageruntime_version function, you can link with nochkclr.obj, which contains an empty version of the function and does not provide for an error message if you run your application on version 1 of the runtime. To build an application with the current compiler version to run on the previous version of the runtime, use /clr:InitialAppDomain.

I was trying to build a atl program in .net, I got this error error C3861: '_L': identifier not found, even with argument-dependent lookup on the line if( lstrcmpiW(szName, _L("Output")) == 0 ) .............. What should I use instead of _L ()?

worked SIZE sizeTotal; sizeTotal.cx= cx; sizeTotal.cy= cy; CScrollView::SetScaleToFitSize( sizeTotal);

I'm using a formview here, setscaletofitsize() is for the scrollview. can you please tell me how I can use it for the scroller in the formview?

It worked. Thanks.... I have another similar question :-) I have two tree controls attached to the tabs in the tab control. To fit the tree control in the tab control what should I do? 'cause I can't write the wm_size handler for the tabcontrol as I'm adding the tree controls in the formview, not in the tabcontrol class.

I used following code Onsize but I'm getting asserting error at line 279 of winocc.cpp CFormView::OnSize(nType, cx, cy); CRect rectView; GetClientRect (&rectView); m_TabCtrl.MoveWindow (&rectView);

Hi, 1. I have put a TabControl inside a formview in the MFC-SDI application. If I resize the window I want the tab control to always fit in the window (that means if I make the window bigger the control inside will become bigger and if I make the window smaller I want the control to get smaller). Please advise how I can do that? 2. How can I make a SDI application non-resizable? Thanks,
