Genarate wrapper classes for Excel type library. Select 'MFC class from TypeLib' option while adding a class. Select 'From file' radio btn and browse for excel type library. For MsOffice 2003 & 2007 type library is in Excel.Exe itself, for older versions it may vary. see how to use the generated classes http://support.microsoft.com/kb/186122[^]

don't worry as long as there is GetActiveObject() API, u can get the running instance of excel and handle the sheets already opened in it  . Have a look at http://support.microsoft.com/kb/238975 and

CLSID clsidExcelApp;
// get CLSID of Excel Application
hr = CLSIDFromProgID(L"Excel.Application", &clsidExcelApp);
IUnknown *pUnk = 0;
// get running object that has been registered with OLE.
hr = GetActiveObject(clsidExcelApp, NULL, &pUnk);
if(SUCCEEDED(hr))
{
IDispatch *pDisp = 0;
hr = pUnk->QueryInterface(IID_IDispatch, (void**)&pDisp);
//use class wizard generated excel type lib classes..
CApplication oApp(pDisp);
CWorkbooks oBooks = oApp.get_Workbooks();
CWorkbook oBook = oBooks.get_Item(COleVariant((short)1)); //First workbook
CWorksheets oSheets = oBook.get_Worksheets();
CWorksheet oSheet = oSheets.get_Item(COleVariant((short)1)); //First work sheet
oSheet.Activate();
CRange oRange = oSheet.get_Range(COleVariant(CString(L"A1")), COleVariant(CString(L"A1"))); //cell A1
COleVariant var = oRange.get_Text();
MessageBox(var.bstrVal, L"Text in cell A1");
}
doesn't work?

i am new in programming and i'm facing this problem.
i have a main frame. and i have a ToolStripMenuItem in my Main Frame. For this menu item, i put a code as below: (1example)
// loadToolStripMenuItem
//
this->loadToolStripMenuItem->DropDownItems->AddRange(gcnew cli::array< System::Windows::Forms::ToolStripItem^ >(2) {this->fromLibraryToolStripMenuItem,
this->newToolStripMenuItem});
this->loadToolStripMenuItem->Name = L"loadToolStripMenuItem";
this->loadToolStripMenuItem->Size = System::Drawing::Size(137, 22);
this->loadToolStripMenuItem->Text = L"Load..";
// ((this is a declaration))
......
((and i put the coding somewhat like below**because i couldnt find the right code))
private: System::Void fromLibraryToolStripMenuItem_Click(System::Object^ sender, System::EventArgs^ e) {
loadfromlib.h ^ openfiledialog = gcnew loadfromlib();
openfiledialog->ShowDialog();
}
when i tried to run the system; in main frame, when i click the ToolStripMenuItem, it does oppened the child frame, but it didnt work well. when the child frame is still opened, i can also click another ToolStripMenuItem as well.
i hope somebody can understand my problem and can help me solving this problem.. please, and thanks in advance...

This is a very dumb question.
Building a compiler usign the C language is really difficult (even if the 'new' language is simple). You should start reading books about compiler construction (for instance the famous 'dragon' book [^]) and consider using tools such flex and bison (see, for instance [^]).
Moreover, asking for the code 'for a new language' (what language?) is really silly.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Never expect a code from a forum, expect a help.
Compiler designing and development is a very complex activity, i don't think, it is good choice to ask about it.
Firstly learn about compiler.
I am sending some of the website that may help u understand the vastness of compiler design.

You forgot to say that it was urgent 
Seriously, you really believe that someone will write a full compiler for you for free  ? On which planet are you living ?

I don't think so.Why is common sense not common?

hi. i want a double cheeseburger, hold the mayo, and a lemonade. thanks. send it to this forum.
while you're at it, get all that for everyone here on the forum. and i'd also like to order blueprints for the design of a mansion. thanks.
just a word of advice, code is not part of the design, it's implementation.

Me think coding the compiler is the least of your problem.
anyway, read this, it's essential reading for anyone who want to write compiler. :
