The error is:
"Run-Time Check Failure #2 - Stack around the variable 'dlg' was corrupted."
COurProgramDlg dlg;<br />
m_pMainWnd = &dlg;<br />
INT_PTR nResponse = dlg.DoModal();

dlg.DoModal() willnot allocate any memory to nResponse!,that may be causing the problem

It occurs after I have these codes in my program.
m_pSocket = new CListenSocket();<br />
<br />
if (m_pSocket->Create(PORT, SOCK_STREAM) == FALSE)<br />
{<br />
AfxMessageBox("failure!");<br />
m_pSocket->Close();<br />
<br />
}<br />
<br />
if (m_pSocket->Listen(1) == FALSE)<br />
{<br />
if (m_pSocket->GetLastError() == WSAEWOULDBLOCK)<br />
{<br />
AfxMessageBox("failure!");<br />
m_pSocket->Close();<br />
}<br />
}

Do you handle any user defined messages in COurProgramDlg or any other class related with it, then check their signature is correct. Or are you calling any function with a different calling conventions ?

Hi
Is there a way to calculate the distance between 2 computers?
Suppose I have 5 computers located in diff. parts of the world. Now I want to send information from 1st computer (say computer A) to the farthest (say computer E). I can easily evaluate the shortest path between 2 computers if I know how to calculate the distance between 2 computers.
Now my question is ->>> Is there a way to calculate a distance between 2 computers?
Some idea, hint or code!
Please help.
Thanks

u could get each computer to ping each other computer and then report back, then u get "distances"

1. What do you mean by 'distance' - physical (i.e. miles), or network (i.e. hops) ?
2. If you mean physical then your premise: 'I can easily evaluate the shortest path between 2 computers if I know how to calculate the distance between 2 computers' is incorrect.

Thanks for replay
I actually want to calculate the best path for sending information from one computer to another.
What I am trying is :
I am trying to build a network where several servers will be distributed to in a wide area. The purpose of these servers will be to deliver fax. I require calculating the best path for this purpose. Actually this is a final year project.

Then do a search for a network 'trace' implimentation.
e.g. Search on keywords: network trace route c++

i made one program in MFC(VC++). i want to give security to my program . i want that if i install my program on one pc. it cannot run on another pc. so i want to use hard disk serial number in my program. but i dont know how to get hard disk number in vc++
plz tell me if any other method to secure my program

Look for [GetVolumeInformation] which return Drives Serial Numbers.
if you really need HarDisk Serial Number I believe you have to Program Using WMI(Window Management Instrumentation.)

What are you showing in your view ? I believe you can set scaling on a DC, that's probably the way to go, if you override OnPaint and set the DC up so that the rest of the painting that takes place will be drawn at a larger than usual scale.

Try using:
SetMapMode(dc, MM_ISOTROPIC);
then,
SetWindowExtEx(), SetViewportExtEx().

UpdateData (1);
for(int m=1;m<=m_edit1.GetLength ();m++)
{
CString tr=m_edit1.Left (m);
tr.Delete (0,m-1);
ch=tr.GetAt (0);
tr.Format ("%d",ch);
data =(double)ch;
//calculate ((data)^e mod n) .i.e the remainder

s.Insert(0,'0');
}
UpdateData (1);
m_edit6 +=s;
UpdateData (0);
this is a code for encryption .here first i converted the string in the edit box 1 to its corresponding ascii value.after that i found the double value for that.for concatenating the values, i converted the double value into string&i stored that value into m_edit6.
for decryption i have to convert that string value in the edit6 to double using "strtod()".
plz help me with this..

Well, that's just plain impossible. strtod converts a string to a double, not a double to a string.

sorry ,actually i meant string to double conversion.
|
|
|
|

if you want to convert string to double use this:
CString string;
char *temp;
double dNumber;
temp = string.GetBuffer(string.GetLength());
sprintf(temp,"%f",dNumber);
