Hello,
I need some help with creating a word maker in Java. the user should be able to enter a list of words at least nine of them (3 x 3) grid will be formed and should be abl to grow.
an import button should be available to import a list of words from a text file into a world list which will be compared with the list of words in the grid.
a make grid button should be availabe to allow the user create the grid after the letters have been entered.
a make word button should also be available for the user to click and search for the words in the grid. the words can be found diagonally, horizontally and vertically.
if i could get some help on how to do this i'll be very greatful thanx.

Hi, I'm a scientist writing a physical model in C using visual studio 6. I have written using C several times before for calculations and i have always been able to sort out any problems, however i have a problem which has me on the verge of chucking my PC out of the window .
The program i have written compiles with no problem, but when i try to run it comes up with stack overflow errors (unhandled exception 0xC00000FD), Visual studio (in debugging mode) asks for CHKSTK.ASM and then SCANF.C, both of which do not exist on my computer. I have tried going through the code with the debugger but the thing crashes immediately after the opening brackets of the main function. I have tried changing the stack size in the project-settings-C C++ and using /F command for the stack size. When i do this it again compiles but there is the same problem even when i start using ridiculous numbers for the /F argument. Help me please !!!!

The debugger asking for SCANF.C suggests that you're using a badly written format string in some call to scanf, sscanf or similar. Can you check that? Also, if the code is not very long you might consider posting it here.

Cheers for the suggestion Joaquín , I'll check it through this evening, unfourtunately the code is rather long, maybe 30 pages with functions and all, and since i dont have the foggiest idea of where it is going wrong i didnt want to post it.
Thanks again.... Mike

If it's crashing after the opening brackets, I'd check any global variables you may have, any constructors that may be failing. You can put breakpoints inside the constructors as well as any statically initialized variables.

Hi, I am trying to write files on a CD RW disk formatted under the Apaptec Direct CD program. If am getting a "File not found" error on return from CFile::Open() - the code (which works on a hard disk directory) is as follows:-
if( !DestFile.Open( sDest, CFile::modeCreate | CFile::modeReadWrite | CFile::shareDenyWrite, &e ) )
{
#ifdef _DEBUG
CString sMsg;
sMsg.Format("Destination file %s could not be opened - error code = ",sDest);
afxDump << sMsg << e.m_cause << "\n";
if(e.m_cause == CFileException::sharingViolation)
afxDump << "ERROR: Sharing violation\n";
if(e.m_cause == CFileException::fileNotFound )
afxDump << "ERROR: File not found\n";
#endif
}
Do I have to do something special with CD RW's ???

Hi!
I try to build an Desktop switcher - like the one in KDE
<br />
CWnd *pWnd = CWnd::FindWindow("Progman", "Program Manager"); <br />
<br />
if(!pWnd)<br />
return;<br />
<br />
CWnd* pChild = pWnd->GetWindow(GW_CHILD);<br />
HWND hWnd;<br />
pChild->GetDlgItem(0x1, &hWnd);<br />
ASSERT(IsWindow(hWnd));<br />
CWnd* pCtrl = (CWnd*)CWnd::FromHandle(hWnd);<br />
((CListCtrl*)pCtrl)->DeleteAllItems();<br />
<br />
LPITEMIDLIST id;<br />
static char path[1024];<br />
SHGetSpecialFolderLocation(hWnd,CSIDL_DESKTOPDIRECTORY ,&id);<br />
SHGetPathFromIDList(id,path);<br />
<br />
CString strDesk;<br />
strDesk = _T(path);<br />
strDesk += "\\*.*";<br />
CFileFind finder;<br />
BOOL bWorking = finder.FindFile(strDesk);<br />
<br />
while (bWorking) {<br />
bWorking = finder.FindNextFile();<br />
((CListCtrl*)pCtrl)->InsertItem(0,(LPCTSTR)finder.GetFileName(),0); <br />
}<br />
The strange think is, that sometimes i can Insert Items without any problem. But sometimes i got an access error. DeleteAllItems works well, but InsertItem causes access errors.
What have i done wrong?
thx cya
sorry for my bad English

Dear All,
I am developing an application in MFC VC++ Version 6.0 for Windows 2000. My application sometimes throws following error just before starting (it come some times,, not always)
.........................
Application Error:
The instruction at "0x102404fa" referenced memory at "0x5b4e4f49". The memory couldnot be "read"
............................
Can anybody tell me what can be the reason behind this ??
Feel free to ask any further queries in this regards,
Thanks
Rohit Dhamija

Looks like a stack corruption. You've probably run off the end of a buffer somewhere.

Hi Taka,
Thanks for replying.
Can you tell me any way to resolve this bug ? Because it is not coming always, only some times..
Stack corruption  ???
Can you tell me possible reasons for stack corruptions..

Buffer overruns are the most common cause. Look at the following code:
char* p = "hello world!" ;
char buf[5] ;
strcpy( buf , p ) ;
The string you are copying is too big for the buffer and strcpy() will just blindly copy past the end of the buffer, blowing away anything that was there.
The other possibility is you are writing through an invalid pointer that is occasionally pointing into the stack.

Thanks takka,
I think this will be of great help in locating possible cause of error.
But my applications is very large and will take long time to find such silly mistake. Can we get some help from the error itself ??? The error stated that
.........................
Application Error:
The instruction at "0x102404fa" referenced memory at "0x5b4e4f49". The memory couldnot be "read"
............................
How can we take the help of this error to find exact location of the culprit .

You can't. If you look at the memory address, you'll see that it looks like string data. You probably put some string data onto the stack and the CPU has tried to interpret it as an instruction address. The #1 cause of this is the code snippet I gave before.

Have you tried running a debug build? (I assume you have, but just wanted to confirm).

I am a very new person to programming in general. does anyone know how make a program that will let me send messages from my comp at school to the others around me similar to the dos command net send)
:P

You could always wrap "net send" in your own application by using ShellExecute().

Check it out in MSDN. If you don't have it installed, check this[^] out.

I want get a associated icon from a file system (for example c:\test.doc") using SHGetFileInfo function and save it in a file (for ex "C:\myicon.ico").
But GlobalSize and GlobalLock returns 0 (invalid value!!!).
Please give me a good idea!
Tnk you
/******MY CODE*****/
CString nomefile = "c:\\test.doc";
HICON hGen32Icon;
HIMAGELIST hSysImageList;
SHFILEINFO shfi;
int fh;
UINT uiSize;
DWORD dwSize;
LPVOID lpGMem;
OFSTRUCT of;
hSysImageList = (HIMAGELIST)SHGetFileInfo
(nomefile,
0,
&shfi,
sizeof (SHFILEINFO),
SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
hGen32Icon = ImageList_GetIcon (hSysImageList,
shfi.iIcon,
ILD_NORMAL);
dwSize = GlobalSize(hIcon); /*Don't work*/
lpGMem = GlobalLock(hIcon); /*Don't work*/
fh = OpenFile ("c:\\myicon.ico", &of, OF_WRITE | OF_CREATE);
if (fh == -1) // If NOT opened successfully.
{
MessageBox("Unable to create file", NULL, MB_OK );
}
uiSize = _lwrite(fh, (LPSTR)lpGMem, (UINT)dwSize);
_lclose(fh);

Hi,
Currently, I need to do read/write on disk sector under Win2000/XP. I found out that the statement below is only valid for administrator.
hDisk=CreateFile("\\\\.\\C:", GENERIC_READ, FILE_SHARE_READ, NULL,
OPEN_EXISTING, NULL, NULL);
...
For non-admin user, the above statement will always return hDisk=INVALID_HANDLE_VALUE. My question is how can we solve this problem? Can we assign access right or privilege in our program in order to access disk sector? or do we need to develop VXD to solve this problem?
Hope that some of you can give me some hints. Thanks in advance!
Best Regards,
K Wan

Yes my friend

Thanx
TAKE CARE
