doesn't that error usually mean you need to include stdafx.h??? Last modified: Wednesday, July 12, 2006 1:13:22 PM --

stdafx.h is included in the project..

If the compiler says "undeclared identifier" it means it can't find it. There are two possibilities:
1. A missing header file.
2. The identifies name is wrong or it's in a namespace and you haven't qualified the name with it or put in a using statement to import it.
Knock number two on the head by adding no_namespace after the #import. i.e.
#import "Voodoo.tlb" no_namespace
This tells the compiler not to use namespaces.

Is there any other way to use COM components in code without importing (#import) and server module (any compnent file like .tlb ). Can anybody suggest me a sample link for the same...?

When the component is authored the interface is probably described in an IDL or ODL file. If so, when it is compiled with MIDL a type library and some C++ header files are produced. If these files are distributed you can use these for C++.
If the interfaces are IDispatch based you could use the library without any type information, but this hard to describe and not the best approach in C++ anyway.

How are you importing your tlb file?
Remember that unless you specify it, you will need to specify the namepace scope. So:
#import "somelibrary.tlb" named_guids
..
..
HRESULT hr = CoCreateInstance(SOMELIBRARYLIB::CLS_ITest, NULL,
CLSCTX_ALL,
SOMELIBRARYLIB::IID_ITest, (void**)&pTest);
..
..
Notice the namepace scope.

Hi all could any one tell me what is the the equivelent the following visual basic 6 code. txtURl holds a url of a perticuler website.Thanks
RichTextBox1.Text = Inet1.OpenURL(txtURL.Text, icString)
|
|
|
|

There is no direct equivalent. Try calling InternetOpenUrl() followed by InternetReadFile().

Googling: MSDN InternetReadFile
produced hits where the second one listed is titled "Building an Internet Browser Using the Win32 Internet Functions". The following sample code is contained in that article which you could have easily found for yourself.
HINTERNET hNet = ::InternetOpen("MSDN SurfBear",
PRE_CONFIG_INTERNET_ACCESS,
NULL,
INTERNET_INVALID_PORT_NUMBER,
0) ;
HINTERNET hUrlFile = ::InternetOpenUrl(hNet,
"http://www.microsoft.com",

from the sample the "char" array named "buffer" would contain the HTML. In C/C++ char arrays are "strings" so basicaly you can copy that buffer into the edit control.
I don't know why you are doing this in C++ from a VB background but things are very different in C/C++ from VB. There are so many different ways to get a char array into a windows edit control depending on "how" you are developing your solution. If using MFC you have classes that you are using that simplify these operations. If not you must send messages to windows controls to interact with them. This is a small part of the fundamental knowledge needed for windows development in C/C++. Asking questions in a forum about using API's when you don't have basic C/C++ experience will be a very slow and tiresome process.

well i have done this in visual basic 6 but i am working in a project that is only possible in visual c++ and this has to be done in visual C++ as well
Any ways still i did not get my asnwer.!! i want to place the html code of the url inside a variable and editbox but adding SetDlgItemText(IDC_EDIT2,buffer); to your code did not compile and gave me 16 erros!!
could u just help me fix that problem

My whole intention is to extract data once i get the html of perticuler url .
I want to extract the bold parts of html as below.could u show me how to collect the bold part data from a webbrowser controle html . I want to collect those data and place them in a listview and use the color code to color the name in listview.
Note: i want to extract the name and color1 and color2 data from webbrowsser controle as shown in pic

this is exactly what I meant about not having C/C++ basic experience. It could take you months and hundreds of posts to finsish your job using a forum.

That means you have not included a required header file. That is basic C/C++ knowledge. A perfect example of what I am telling you. If you are going to develop using VC++ you better go back to the start and learn some basics, jumping into an actual project when you don't even know about including header files is completely insane.

Buy a book for beginner C++ . Don't do a project until you actually understand everything in the book. Once you understand everything in the beginner C++ book you will have scratched the surface. 
Then repeat for Windows Development.
Then repeat for HTTP and HTML ( of course this book may not exist ). 
Of course there is the famous book "Learn Visual C++ in 21 days". You could try that one... and if in 21 days you have actually learned Visual C++ "completely" you should donate half your salary for the next 5 years to the author.

man i have the book Learn Visual C++ in 21 days and i read first few chapters. so u think your solution will allow me get the dynamic html that i need for further process corectly? The reason i want to make sure is that the html that i am after is dynamic and i need to retrive it every one min so i do not want to get the old html for each request.
Furthermor, could u tell me what chapter of that books talkes about retriving html ?

I must apologize.  My comments about that book are pure sarcasm. No one can learn Visual C++ in 21 days. I have no idea what is in the book because the title is so stupid I would never read it or recommend it.

First, I thank those who provided their feedback from earlier post.
I need some tweaking once again
As stated earlier, I have a program that should accept only keyboard input of integers from 1 to 12.
Someone suggested I try the scanf() function. I did something with it as shown below. Currently, it allows all integers as valid input and no other characters (letters, punctuatation, symbols, ect . . .).
This is fine. But, how can I further restrict user input with the scanf() function to allow only integers 1 thru 12? Or should I use another method? This is my first time using scanf. I've already tried the while conditions
while (data >=0 || data <= 13), (data >=0 && data <= 13) with not much luck. At this point I'm not sure if I should change how I'm retrieving the data (thru cin or getline). This is a very pivotable part of the program and the whole program is dependent on this functionality. Help is appreciated. 
char buff[1024];
unsigned int value;
int charsRead;
bool validEntry = false;
while (!validEntry)
{
cout << "Please enter the number of subunits: ";
cin.getline(buff, 1023, '\n');
if (sscanf(buff, "%u%n",&value,&charsRead)==1)
validEntry = true;
}
