Understood. I should have read a bit closer. As I've never programmed games, I'm not much help. Maybe a walk-through of DirectX would prove useful.

hi there,
you must first learn how to be a programer
1]get some stuuf in computer scince
a)http://computer.howstuffworks.com/
( to learn how computer hardware works)
b)get some free books in programming from
(http://www.maththinking.com/boat/computerbooks.html)
to learn about how to write a good algorith.
2]learn visual c++
3]get microsoft directx sdk,opengl sdk & some modern game design book.
after doing that you will be a great games programmer

You are right! You have to learn to think like a programer, and that comes with understanding plus experience. There are some totorials at codeproject that may help, such as pointers.
One of the best ways I know of (when starting) is to take a look at the C library functions (strlen,strcpy,strtok,etc...) and try to write your own versions.
Example:
int MyStrLen(const char* pStr)
{
int i;
if( !pStr )
return 0;
for( i=0; pStr[i]; ++i ) {}
return i;
}
int MyStrLen(const char* pStr)
{
int i = 0;
if( pStr )
for( i=0; pStr[i]; ++i ) {}
return i;
}
int MyStrLen(const char* pStr)
{
char* pStart = pStr;
if( pStr )
for( ; pStr; ++pStr ) {}
return (pStr - pStart) / sizeof(char);
}
If you know why each of the above works, then you are well on your way!
As for game programming there are lots of sights where you can look, but none of them will do you any good unless you understand the language. Also, game programming is very math intensive; so you will need to be very good at mathmatics.
Well, have fun and learn all you can!

Any thoughts on the problem below will be a great help:
I am trying to use CFile in an MFC app. My thinking is that it should be available with no further includes as stdafx is included which includes windows.h? However vc++ tell me CFile is an undeclared identifier. CFile is declared in afx.h however I can't include afx.h by itself as the compiler complains that windows.h is being redeclared.
What am I missing...

By default, windows.h is not directly included in stdafx.h. You should have at least included afxwin.h. Others you might have are afxext.h and afxdtctl.h.

Many thanks!
This has pointed me on the right track. I have found similar posts and the answer seems to be afxwin.h.
Unfortunately I still can't compile:
_DllMain@12 already defined in HookFunc.obj
I have found a Microdoft specific knwledge base article describing this problem but that relates to specific modules that there is a problem with. I don't think that's what I'm seeing, more likely I'm just doing something dumb.
Just another typist

It appears that you have more than one instance of DllMain() in the project's .c or .cpp files.

In a part of my project, I must compile many HTML files into a single file ,I decided to choose CHM file. But how can I do this using C++? I know HTML Help workshop,but it's only a tool. I didn't get much on MSDN.I am using Visual C++ 6.0. many thanks.

Why dont you use HTML Help workshop but using its comand lines, this way you'll compile by code, but by issuing the right command using CreateProcess or the likes.
Check in the help for the different command lines and the one you could need

You can create the hhp project file (and, if you need, the contents/index files) dynamically, and then execute hhc.exe (which is the compiler, with the hhp file as argument).
Creating the .chm directly is probably a major and very painful project, just to figure out the format will take some time (there's an incomplete documentation at wotsit[^]).
(OTOH, it would make a cool CP article  )

Hi guys. I need help, I dont even know if Im putting this in the right FORUM... but here it goes.
Ive been asked to create a Point of Sale application that can control a recipt printer and a cash register. I HAVE NO IDEA WHERE TO START. as of now I know that the printer and cash register is connected through LPT1...THATS IT!!..
please help..
Im pretty good at handling web applications and flash...so if there is anyway that I could create componets that I might be able to manage through a web application and SQL/Access database...It´d be great.
Thank you very much...

The printer and register should have provided you with some sort of interface instructions (e.g., send such-and-such code to open cash drawer). Without that, how are you going to know what commands to send, and how to interpret the commands that you receive?

So you want to create a "web based" - "point of sale application"?

well. Im not stuck on the idea that it has to be web based..but I did want to use the visual benifits that FLASH can give me for this application...therefore I need to create other components (.DLLs for example) that I could control (send and recieve data) through my FLASH and save into a database for inventory, statistics and other information..
Im interested in the DLLs that can recieve and send info to the cashier, so that my web interface can know when the register is open or closed...or..so that I can OPEN the cashier through my FLASH movie..
With this I can save a log in my database of when and by who the register was opened..(I would have a previous login)

 I design my DirectX project like this:
CScene{
...
creat Driect3D object,
creat Driect3D device,
render()
...
}
and I need a instance of CScene in MFC framework.
There should be only one instance of CScene in the whole porject, is that right?
The question is which class I should implement the CScene? I want to get the best effciency!
Any exam code is welcome~~
Many thanks!

I have a derived class of CCheckListBox. I would like to prevent the checkbox from appearing on certain items in my list. I have overridden the DrawItem and MeasureItem routines, but don't want to simply just paint over the rectangle area that encompasses the checkboxes. Is there a field in the LPDRAWITEMSTRUCT that I can set to a particular value that would remove the checkbox for a particular item? If there is a solution for this, will it also remove the framework event handling of the mouse clicks in the checkbox region of the list item?
Thanks,
Bob

Hi all, how to open the document with the exiting MS Word Application?
I used CreateToolhelp32Snapshot() to find out whether MS Word, MS Excel, and MS Powerpoint exe files are open. Then I want to open the file ( .doc file with MSWord, .xls file with MSExcel, .ppt with MSPowerpoint) with exiting application.
I used mswApp.CreateDispatch(TEXT("Word.Application")) to open word application. But I dont want to open the application, then close it after the document is closed. I want to just open the application once.
Now I know whether the application is already open or not.
How to do the next step, open the document with application already opened?

I know about ShellExecute() and ShellExecuteEx().
However I have to format those office files (.doc,.xls,.ppt) such as formating the page setup like page size, margins, quality, paper size, etc., formating font size, and also printing out embedded objects in word document. Therefore, I have to use automation.
However, I am encountering the error in my program.
The function is marshalled to other thread
here what I do,
I have a dialog that has 3 buttons, print, stop printing, and exit.
when you click print, the program will get files name from database and send it to printer. The printer send message (window message) END_DOC when the file get printed and the program catch the message and send the next file. Meanwhile, if the user click on stop printing button, the program stop immediately.
Inorder to stop printing, I have use following code.
dlg->openApps() opens ms word, excel, and powerpoint application just simply using CreateDispatch().
dlg->closeApps() closes or quite applications.
PrintTheFile() gets the file name, and send it to printer
<br />
UINT PrintingThreadFunction(LPVOID lParam)<br />
{<br />
CMyProgDlg *dlg = (CMyProgDlg *) lParam;<br />
bool openapps = true;<br />
dlg->openApps();
while(!stopprinting)
{<br />
if(isprinting == NO)
{ <br />
dlg->PrintWordDoc() ;
}<br />
if(stopprinting == (int)YES || dlg->quite)<br />
break;<br />
} <br />
dlg->closeApps();
}<br />
<br />
<br />
void CMyProgDlg::OnBnClickedPrint()<br />
{<br />
CWinThread *printingThread; <br />
printingThread = AfxBeginThread(PrintingThreadFunction,this);
printingThread->m_bAutoDelete = FALSE;<br />
}<br />
To catch the message sent by printer I used following code.
<br />
LRESULT CMyProgDlg::OnPrinterMsg(WPARAM wParam, LPARAM lParam )<br />
{<br />
.....<br />
.....<br />
case End_DOC:<br />
PrintWordDoc();<br />
}<br />
Opening and closing office applications take 7 secs to open and 7 sec to close. I want to speed up my program by opening those applications once and close it at when user quite the program.
How to just open those applications once and open the document over and over again with exiting application (.doc with msword, .xls with excel, .ppt with powerpoint)?
thank you

I am trying to start an application on a remote PC with CreateProcess(), but it is executed on the local PC instead. You will see that I just call CreateProcess() putting "\\otherPC" in front of the path of the application. The code is listed below:
PROCESS_INFORMATION processInfo;
STARTUPINFO startupInfo;
GetStartupInfo(&startupInfo);
DWORD processCreationFlag=CREATE_NEW_PROCESS_GROUP|CREATE_SUSPENDED;
startupInfo.dwFlags = STARTF_USESHOWWINDOW;
startupInfo.wShowWindow = SW_SHOWNORMAL; // SW_SHOWMINIMIZED;
strcpy(startupInfo.lpDesktop, "");
startupInfo.lpTitle=NULL;
char *startingFolder=strdup("\\\\otherPC\\C\\DIM\\ImsVisualization\\bin");
char applicationName[512];
sprintf(applicationName, "%s\\iMSVisualization.exe", startingFolder);
if (CreateProcess(applicationName, NULL, NULL, NULL, true, processCreationFlag,//|CREATE_NEW_CONSOLE,
NULL, startingFolder, &startupInfo, &processInfo)==0)
{
printf("Could not start Visualization\n");
}
else printf("Visualization started successfully\n");
return 0;

You can't use CreateProcess() in this fashion. What you've done is run an application, that resides on another machine, on the local machine. Search CP and MSDN for RPC examples.
