Well, I've learned most of the fundamentals of c++ and am feeling quite comfortable with the concepts involved. I've investigated Microsofts express development studio, but before I begin installing a development studio I would like to find a good tutorial for Visual C++. I have looked around on the web, and haven't been able to locate what I think is a good tutorial, and I was hoping that somebody here would know of a good place to start. I would like the tutorial to begin with the basics of VC, not necessarily c++ ( how to make basic windows etc.) and hopefully lead into some of the more advanced concepts involved with how to work with the windows API (threads, memory etc).
Any suggestions.

I would suggest Petzold's book.

Okay, Hope I've fixed my name now.. Sorry about that, I made this account awhile back. Thanks for your suggestions everybody, but most of these examples (excluding perhaps the book) seem more like reference material. I was looking around some more and found http://serghei.net/docs/programming/c++/ty%20visualC++6%2021%20days/ewtoc.html[^]
This is what I was more looking for, something that can be followed throughout a set course. Although this seems a tad bit outdated, can anybody comment on if this tutorial is any good, or any more up to date suggestions are more than welcome.

My existing code is below. A global function which is not a member of any class is calling a function which is a member of class CNewDlg. This code works, but I don't like it. I'm using it because it's the best I have been able to do. I think it can be done better using a user message, but I don't know how user messages work and haven't been able to find any examples. How would I code this using a user message?
void WINAPI HostChange(LinkPtr data) <---global; not in any class. A callback provides ptr data.
{<br />
((CNewDlg*)AfxGetApp()->m_pMainWnd)->LogonChange(data); <br />
}<br />
<br />
void CNewDlg::LogonChange(LinkPtr data) <---function in a dialog class
{<br />
if(data->SomeField == 3){Do something...}<br />
}

I'm with you on this! 
Here's an ultra-easy alternative, which while not perfect, has its advantages.- Add 2 buttons (
IDC_HOST_CHANGE and IDC_LOGON_CHANGE) to CNewDlg and make them invisible.
- Write a handler for each - the one for
IDC_HOST_CHANGE should call HostChange() and the one for IDC_LOGON_CHANGE should call LogonChange().
HostChange() and LogonChange() should get a pointer to an (perhaps the) instance of LinkPtr via a singleton access method exposed by your app class.
- Your static callbacks should post the appropriate message to your app's
AfxGetMainWnd(). No casting to CNewDlg is required. For example:
AfxGetMainWnd()->PostMessage (WM_COMMAND, IDC_HOST_CHANGE);
In lieu of a registered message, this provides a clean separation between event generation by your application's innards and event handling by your application's user interface.

Here's a quick, general introduction to user-defined messages. I'm assuming you're using MFC here.
1. Define a message identifier. You can base it off of WM_USER or WM_APP:
#define WM_MY_MESSAGE (WM_APP + 1)
2. Declare a message handler in your dialog class:
afx_msg LRESULT OnMyMessage(WPARAM wParam,LPARAM lParam);
3. Add an entry to the message map for your dialog class:
BEGIN_MESSAGE_MAP(...)
ON_MESSAGE(WM_MY_MESSAGE,OnMyMessage)
END_MESSAGE_MAP()
4. Define your message handler:
LRESULT MyDialogClass::OnMyMessage(WPARAM wParam,LPARAM lParam)
{
}
5. Finally, send the message when needed:
my_dialog->SendMessage(WM_MY_MESSAGE,
(WPARAM)first_parameter,
(LPARAM)second_parameter);
where first_parameter and second_parameter are whatever values you want to send with the message.

Is there any method to change the shape of the window.

Its SetWindowRgn.
From the MSDN
This function sets the window region of a window. The window region determines the area within the window where the system permits drawing.
The system does not display any portion of a window that lies outside of the window region.

Hello,
How i can change LocationName property of IWebBrowser2 ?
I try to use GetProperty/PutProperty but it's not works:
BSTR bstrPropName = L"LocationName";
VARIANT varPropValue;
varPropValue.vt=VT_BSTR;
varPropValue.bstrVal=L"this is a test";
m_spWebBrowser->PutProperty(bstrPropName,varPropValue);
it's not return any error but not change LocationName value 
Can you give me any example of using GetProperty/PutProperty ?
Thanx for help !

You are mis-using BSTR. You need to create them properly with SysAllocString(), or use a wrapper class like _bstr_t or CComBSTR.
|

What Michael mean by his answer is, you could modify your code like this,
BSTR bstrPropName = SysAllocString(L"LocationName");
VARIANT varPropValue;
varPropValue.vt=VT_BSTR;
varPropValue.bstrVal=SysAllocString(L"this is a test";)
m_spWebBrowser->PutProperty(bstrPropName,varPropValue);
SysFreeString(varPropValue.bstrVal);
SysFreeString(bstrPropName);

Error msg:
c:\program files (x86)\microsoft visual studio\myprojects\window\winmain.c(44) : error C2275: 'D3DPRESENT_PARAMETERS' : illegal use of this type as an expression
I am not sure what is causing this error. I have the DirectX 9.0 SDK installed. I am using Visual C++ 6.0 and added d3d9.lib and the directory for the include. The only thing different is I have Vista Premium 64 bit version. The windows code works fine. I can't get it to compile DirectX headers? I have also tried it with the free version of Visual c++ 2005 and still getting errors? I have tried running it as an Administrator. Any ideas how to get this working?
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory( &d3dpp, sizeof(d3dpp) );
d3dpp.Windowed = TRUE;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;
if( FAILED( g_pD3D->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp, &g_pd3dDevice ) ) )
{
return E_FAIL;
}

The problem is that the D3DPRESENT_PARAMETERS is not defined. Make sure you have included the correct headers in the correct order. Your version of VS will make no difference.

Hi ,
I have a HDC and I want to convert it to Palette??
So I can get a color table??

You cannot convert a DC into a palette. A DC is a container which holds many things for drawing, but it can only hold 1 of each thing at any time. It holds things like pens, fonts, brushes, bitmaps and palettes.
Usually you need to make a palette then select it into the DC. Can you tell me why you need a palette? maybe then I will be able to give you a better solution.
