It crashs in the InternetWriteFile function with a access violation exception.

You should set the second parameter to FALSE when don't excect answer from FTP server.
Or you need to call the InternetReadFile function before.
fExpectResponse
A Boolean value that indicates whether the application expects a data connection to be established by the FTP server. This must be set to TRUE if a data connection is expected, or FALSE otherwise.

Hai!
suppose
CString str = "This is our Book";
CString strSub = "my";
is there any function which can modify str with the value in strSub
like str.MODIFY(strSub, 9, 2);
then str must become "This is my Book"

Your productivity and efficiency will increase exponentially if you refer the documentation.
CString::Replace

Well, just think about the problem. You want to make a new string from a left section of the old string, some new string, and the right section of the old string.
That should be enough hints!

I have a vector that contains POSITIONs. When I try to push_back or clear, the program crashes. The callstack shows _invalid_parameter_noinfo in one of the frames. I googled and found a solution(defining _HAS_ITERA.... and _SECURE_SCL to 0) , but was not effective. I'm using VS2008 with MFC feature pack installed on vista.
Please help.
Thanks

Can be due to a lot of reasons. Could you please provide relevant code snippet and call stack during crash?
Regards,
Jijo.

Why are you mixing MFC collections with STL ones?

Is it a serious issue(mixing MFC with STL)? please explain.

It's not FATAL - but the two mindsets of the framework designers are quite different.
So you're setting yourself up for confusion. Which is never good. I find it confusing enough just getting out of bed.

The problem is still not solved.
I have some classes that inherit from vectors.
I have a vector of POSITION(in afx.h)
struct __POSITION {};
typedef __POSITION* POSITION;
So when I try to push a POSITION value to the vector<position>
I get this crash saying invalid parameter.
In call stack I see its trying to push(insert) a value of different type (ref. classes that inherit from vectors) other than POSITION. How is this possible?
Please help!!!

Nope, if you're able to master both. Anyway, if you're able to master both then you don't mix them.

Looks like a CRT invalid argument error. You can use _set_invalid_parameter_handler[^] to set a custom handler for whatever invalid argument is being passed. Note that not correctly handling the error could mask the real problem.

I had the same problem when porting from VS2005 to VS2008.
I avoided it using dynamic allocation something like this:
std::vector<???> *v;
v = new ???;
v->push_back(***)
This works in both debug and release mode ^^

hi all,
I m using a ListCtrl,here diffrent rows and column are present.
for example there is 10 row and 4 column.
i want a RECT value for corresponding row and column.
i m using this.
CRect CDemo::GetCellRect(int nRow, int nCol)
{
ASSERT(nCol >= 0 && nCol < m_nPageCols);
ASSERT(nRow >= 0 && nRow < m_nRowCount);
CSize charSize = m_CharSizeBody;
CRect rectBody = m_rectBody;
CRect rectCol = GetColumnRect(0);
for (int nLeft=0, i=0; i < nCol; i++)
nLeft += GetColumnWidth(m_nColumns[i]);
int nRight = nLeft + GetColumnWidth(m_nColumns[i]);
int nPageRow = nRow % m_nPageRows;
ASSERT(nPageRow <= m_nPageRows);
CRect rect(
rectBody.left + nLeft,
rectBody.top + rectCol.Height() + charSize.cy * nPageRow,
rectBody.left + nRight,
rectBody.top + rectCol.Height() + charSize.cy * (nPageRow + 1));
if (rect.right > rectBody.right)
rect.right = rectBody.right;
rect.left += (int)(CELL_PADDING * m_RatioX);
return rect;
}
but this gives some wrong values.
for all columns in one row its gives same value and put data in 1st column.
i want to put data in corresponding row and columns.
please correct me.
thanks in advance.
IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

Why dont' you use GetItemRect and GetSubItemRect?

Hi all,
What is wrong in this problem. Is this the right way to handle?
#include <iostream.h>
class MyErrorClass
{
char *reason;
int *i;
public:
MyErrorClass(char *r)
{
i = new int[6];
cout<<;"Constructor<<endl;
reason = r;
cout<<reason<<<endl;
}
char* giveReason()
{
return reason;
}
~MyErrorClass()
{
cout<<"destructor"<<endl;
delete[] i;
}
};
void main()
{
try
{
throw MyErrorClass("error");
}
catch (MyErrorClass &e)
{
cout<<"Exception caught --- <<e.giveReason()<<endl;
}
}
Thanks
San

I hope you got a crash when you run this code snippet. I rewrote it like this. It allocates the MyErrorClass then throw it. On the top level function, you can delete it. Check the code snippet.
void main()
{
try
{
throw new MyErrorClass("error");
}
catch (MyErrorClass* e)
{
cout<<"Exception caught --- "<<e->giveReason()<<endl;
delete e;
}
}
[Added] As pointed out by Stuart, it will be better to catch the exception object by reference itself. But here the problem is your MyErrorClass is not well written to handle its allocation which can cause crashes(I had). Hope you've already went thought Stuart's explanations.
Regards,
Jijo.

Ummm - no. You definitely should not get a crash when you throw an exception object (as opposed to an exception pointer). The exception declaration does not define the lifetime of the exception - the runtime copies it (or something like that, anyway).
Try the following - you'll find it doesn't crash...
#include <stdexcept>
#include <iostream>
int main(int, char**)
{
try
{
throw std::runtime_error("Test");
}
catch(std::exception& e)
{
std::cerr << "Caught exception - " << e.what() << std::endl;
};
}

Well Stuart, try with this code snippet. Its the same code snippet provided by Ron. I made it compilable. I'll be surprised if it didn't crashed in your system.
class MyErrorClass
{
char *reason;
int *i;
public:
MyErrorClass(char *r)
{
i = new int[6];
cout<<"Constructor"<<endl;
reason = r;
cout<<reason<<endl;
}
char* giveReason()
{
return reason;
}
~MyErrorClass()
{
cout<<"destructor"<<endl;
delete[] i;
}
};
void main()
{
try
{
throw MyErrorClass("error");
}
catch (MyErrorClass* e)
{
cout<<"Exception caught --- "<<e->giveReason()<<endl;
}
}
Regards,
Jijo.
