Hello!
If grammar in your language is simple
You must learn about(as minimal) regular expression:
http://www.codeproject.com/cpp/OwnRegExpressionsParser.asp
if grammar in your language is difficult(above 50 grammar rules), you must learn compiler design theory and use compiler-of-compiler for example yacc.

I know this may be an easy beginner question but it drives me crazy and I've alredy spent 3 hours on this.

I added the followilng libs to the linker:
d3dxof.lib
dxguid.lib
d3dx9dt.lib
d3d9.lib
comctl32.lib
winmm.lib

and the included files:
#include "./Common/d3dfont.h"
#include <windows.h>
#include <d3dx9.h>
#include <stdio.h>

Now I'd like to create a global font:

static CD3DFont* Font1 = new CD3DFont(_T("Arial"), 20, D3DFONT_BOLD);
static CD3DFont* Font2 = new CD3DFont(_T("Arial"), 10, D3DFONT_BOLD);

when I compile the whole thing the linker gives me an LNK2019 error, unresolved external symbol.

I think I've had the same error when I first used a dx-function, but I could solve the problem with the right lib-file.
I searched through the Text3D-example of the sdk but I can't find the point my project file is missing Frown | :(

Must I export some else other files (I've only exported .exe file) so I can run the .exe file in other pc's different from where I compile and debug the applications?
Thank you in advance!

hi,

open your exe with "dependency walker". Now you can see which files (dll, sys,...) your exe needs to run.

In the past I used a speech SDK from Microsoft and in the documents it lists the modules that you need to include in your install program.. I don't remember any specifics (was quite a while ago), just thought you may have over looked that..

I want to print bitmap on full page, so i wright:
[code]
void CtestView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
int cxPage = pDC->GetDeviceCaps(HORZRES);
int cyPage = pDC->GetDeviceCaps(VERTRES);
Graphics g(pDC->m_hDC);
g.DrawImage(m_pBitmap, 0, 0, cxPage , cyPage );
}
[/code]
Thats ok in preview but not in printer. What transformations i need to do?

This is due to a printer DC and a screen DC having different levels of support. Take a look at my "Printing tips and tricks from the trenches" article in the printing section. It has a method to solve this problem.

You need to make use of the procedure that changes a DDB to a DIB and use StretchDIBBits() to plot it. This command is much better supported by printer DC's. BitBlt usually fails miserably.

{
int cxPage = pDC->GetDeviceCaps(HORZRES);
int cyPage = pDC->GetDeviceCaps(VERTRES);
Graphics g(pDC->m_hDC);
g.SetPageUnit(UnitInch);
g.DrawImage(m_pBitmap, 0, 0, cxPage/g.GetDpiX() , cyPage/g.GetDpiX() );
}

Hello!
Try using catch(...) statement to prevent system exception handling.
UINT MyThreadFunc(LPVOID pArg)
{
try {
// code which cause an exception
}
catch(...)
{
// empty or your own handling code
}
}

overloading operator() in c++

Can anyone help me find what's wrong with operator() overload pls?

#include <iostream>
using namespace std;

class A
{
public:
int value;

A(int a) : value(a) {}

operator int()
{
return value;
}

void operator ++ () // prefix
{
value = value+1;
}

};

int main()
{
A a1(27);
++a1; // this works fine...

// the following does not...MSVC6 tells me "error C2064: term does not evaluate to a function"
cout << "value:" << a1() << endl;
return 0;
}

Any ideas?! Many thanks...!
