Hi there,
I am learning C and I am stumped by this question about for loops. I know how to make a loop but not sure how to get the 1*1*1 etc into total.
Given int variables k and total that have already been declared , use a for loop to compute the sum of the squares of the first 50 whole numbers, and store this value in total . Thus your code should put 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total . Use no variables other than k and total .
Thanks in advance,
Jennifer

How about this? [edit]Got the wrong number in the for statement  [/edit]
total = 0;
for(k=0; k<50; k++)
{
total = total + (k * k);
}

Thanks so much. I just had the total equation wrong!! YEAH!! Thanks so much.

Hi,
k=1;
total=0;
while(k<=50)
{
total=total+(k*K);
K=k+1;
}

Given an int variable k that has already been declared , use a while loop to print a single line consisting of 97 asterisks. Use no variables other than k .
or this....
Given an int variable n that has already been declared and initialized to a positive value , and another int variable j that has already been declared , use a while loop to print a single line consisting of n asterisks. Thus if n contains 5, five asterisks will be printed. Use no variables other than n and j .
Any ideas. I have lots of questions like this. I just need help with one of them so I can work with the rest!
Thanks in advance.

Hi
int k=0;
while(k<97)
{
printf("%c",'*');
k=K+1;
}

Hi, I've used Visual C++ for a couple of years, but I'm just learning MFC for C++ .Net right now.
Anyway, I'd like to be able to click a button that gives me a new dialog box (or just hides everything on the current one and gives me a box that looks new). Say I click on a 'stats' button. I'd then like to select from a 'stats' menu which kind of stats I would like to display, etc.
What would be the easiest or best way to accomplish what I'm trying to do in a MFC app?
Thanks,
Mark

I want to be able to take an unsigned int, and use the 32 bits that make up that int for some further calculations.
Is there a way of doing this, via some library, or some built-in function???

Hi,
In the application I've created, I need to do the following:
1. Need the application to ask for the user to save the changes made when he exits without saving. I tried:
GetDocument()->SetModifiedFlag(true);
With this the string displayed in the message box becomes:
"Save changes to untitled?" I need to make this "Do you wish to save changes made to configuration?"
2. Change the application name that appears in all the message boxes (in the title bar). How do I do that? Currently all of them show "xyzProject" and I need "XYZ Application"
Thanks in advance!

You'll need to provide your own SaveModified() method.

This comes from the app's m_pszAppName member variable.

Thanks a lot! This was awesome. I appreciate the assistance you have provided me and the time you've spent answering questions from a beginner like me.
Are there any books that go into more detail about the communication model etc here? I see a lot of books with stuff on how to get started and build your first appln, but nothing more detailed.

You can use
The DCB structure defines the control setting for a serial communications device.
after this you can comunicate as you sain with createfile and writefile..

Make sure you close the file before you try to execute it.. Just a guess.

Specify the file access flag as CFile::modeWrite in CreateFile Function.
I hop this will work.

the means and in God, the hot

I have some souce cod please look into, this will append at the end of the file.
void WriteOutputDebug(char* tempStr, int length)
{
HANDLE hfile;
DWORD word;
char tempBuf[20] = "C:\\OutputDebug.txt";
hfile = CreateFile(tempBuf, GENERIC_WRITE | GENERIC_READ, NULL, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
SetFilePointer(hfile, 0, NULL, FILE_END);
WriteFile(hfile, tempStr, length, &word, 0);
CloseHandle(hfile);
}

Hello,
I am trying to pass data through a CSocket using CSocketFile and CArchive.. Everything works great except if the network connection breaks it thows a CFileException when sending.. I am trying to handle the exception with the following code..
2 problems:
1st) is when I exit the app i get a memory leak, I am guessing that it's because the ar_send.Flush() is what is throwing the exception so the archive data doesn't get flushed..
2nd) the exception throws up a MessageBox and I don't want that, I want to handle the error on my own.. Here is what I have...
CSocketFile sf(&m_sSocket);
CArchive ar_send(&sf, CArchive::store);
TRY {
ar_send << strSend;
ar_send.Flush();
ar_send.Close();
sf.Close();
}
CATCH_ALL(error){
TCHAR szCause[4096];
error->GetErrorMessage(szCause,4096,NULL);
TRACE("OnSend() Error: %s\n",szCause);
} END_CATCH_ALL;
Thanks!
Rob

I found a article on another site that talked about my problem.. here is a little blurb from the article...
If the terminating socket has been closed, calling Flush on the CArchive will raise an exception (so will calling Close). In the previous case, before the exception is handled, CArchive goes out of scope and its destructor calls Close. Close throws another exception and all hell breaks loose. Never throw exceptions from destructors.
You will need nested try / catch blocks ... [Article^]
My problem with the exceptions is fixed but I still have a memory leak.. Any ideas??
void CMainFrame::OnSend(CClientSocket *pSocket, CString strMsg)
{
if(*pSocket != INVALID_SOCKET)
{
try
{
sendObject(pSocket, strMsg);
}
catch (CException* pEx)
{
pEx->Delete();
}
}
}
BOOL CMainFrame::sendObject(CClientSocket *pSocket, CString strMsg)
{
BOOL bRet = TRUE;
CSocketFile sf(pSocket);
CArchive ar_send(&sf, CArchive::store);
try
{
ar_send << strMsg;
ar_send.Flush();
ar_send.Close();
sf.Close();
}
catch (CException* pEx)
{
bRet = FALSE;
pEx->Delete();
}
return bRet;
}
