For instance you can do:

CString s = "#Sample.jpg#TSXGMP850_EN_V10.pdf";
CString szAttachment[10];
int iAttachment = 0;
int iStart; // skip first #
int iEnd;

for ( iStart = 1, iEnd = 0; iEnd != -1; )
{
  iEnd = s.Find("#", iStart);
  if ( iEnd != -1 )
  {
    szAttachment[iAttachment] = s.Mid(iStart, iEnd-iStart);
    iStart = iEnd + 1;
  }
  else
  {
    szAttachment[iAttachment] = s.Mid(iStart);
  }
}

Please note that above code is (intentionally, for concision purposes) not robust.

You've made it appear far more complex than it actually should be. Is that intentional? Big Grin | :-D

Nope. I didn't know about esoteric ReverseFind and it is a bit more general than yours.

hi..
Thank you its working fine..

now i want to append that attachment file to mail path...

Example my mail Path is
"https://testsrv1.ifit.com/Exchange/Administrator/Inbox">https://testsrv1.ifit.com/Exchange/Administrator/Inbox /ss.jpg"

I need to appen after Inbox/
first attachment file
example

"https://testsrv1.ifit.com/Exchange/Administrator/Inbox">https://testsrv1.ifit.com/Exchange/Administrator/Inbox/sample.jpg"...

Well, you known, CString as a concatenation operator called +. Hence, for instance:

CString sPath = "MyFolder";
CString sMyAttachment = "sample.jpg";
sPath += "/" + sMyAttachment;

makes sPath equal to "MyFolder/sample.jpg".

hi ..
no Pallini...
i have my mail Path as

"https://testsrv1.ifit.com/Exchange/Administrator/Inbox">https://testsrv1.ifit.com/Exchange/Administrator/Inbox/Example.jpg"

I need to append my attachment file sample.jpg and remove that Example.jpz..
means i need to first get

"https://testsrv1.ifit.com/Exchange/Administrator/Inbox">https://testsrv1.ifit.com/Exchange/Administrator/Inbox/

then append sample.jpz to that ok.

thank you

To remove the final part of the path (i.e. Example.jpg) use the (our friend Rajesh R Subramanian suggested) esoteric CString ReverseFind method (searching for the slash).
For instance

szPath = szPath.Left(szPath.ReverseFind('/'));

I would suggest that you read up and experiment a little on CString. CString will give you everything that you need.

Here is an example^*:

CString str = _T("Path/Old.jpg");
int iPos = str.ReverseFind('/');
str.Delete(iPos,str.GetLength()-iPos);
str += "/New.jpg";
AfxMessageBox(str);

^*This example uses the esoteric ReverseFind() method. Smile | :)

Will the pattern of the string be same all the time? If it won't, then you may need to write a generalised approach.

Assuming that the pattern of the string will be the same, here is a way to do what you want:

CString str = _T("#Sample.jpg#TSXGMP850_EN_V10.pdf");

CString str1, str2;

int iPos = str.ReverseFind('#');
str2 = str.Mid(iPos+1);

str1 = str.Left(iPos);
str1.Remove('#');

AfxMessageBox(str1);
AfxMessageBox(str2);

If you are using MFC, see if AfxExtractSubString() will work for you.

Can any one tell me that ..How to do Asynchronous Data Transfer through Serial Port.

Event based Serial communication,,,that means when any data come from serial port then,the particular function need to be called!!!!
the program does not wait long time for any data coming from Serial port.

Somebody suggested use callback functions!!!!!!but how?????

thanks in advance..

I should be done using Overlapped IO optionally using IO completion routines. [Synchronization and Overlapped Input and Output^]

I did a quick CP search got this, may be useful for reference how to use overlapped serial communication [CSerialPort v1.03 - Serial Port Wrapper^]

Hey everybody,
I'm using MS Visual C++ 6.0
I do have a code which contains classes in classes. Most inner class has a char** pointer which allocates memory using malloc function and adds a char array to string array.
To be more specific:

<br />
a = (char**) calloc(10, sizeof(char)); // main array<br />
<br />
for (int i = 0; i < 10; i++)<br />
{<br />
    a[i] = (char*) calloc(10 , sizeof(char)); // char arrays<br />
}<br />

the problem is I want a destructor which free this array.
Says Access Violation each time I try to execute. D'Oh! | :doh:

here is my code:

<br />
#include "stdafx.h"<br />
#include <malloc.h><br />
#include <stdio.h><br />
#include <conio.h><br />
<br />
<br />
class sub<br />
{<br />
public:<br />
	char** a;<br />
<br />
	sub();<br />
	~sub();<br />
};<br />
<br />
<br />
sub::sub()<br />
{<br />
	a = (char**) calloc(10, sizeof(char));<br />
<br />
	for (int i = 0; i < 10; i++)<br />
	{<br />
		a[i] = (char*) calloc(10 , sizeof(char));<br />
	}<br />
<br />
	printf("\n%x - %x - %x\n", a[0], &a[0], *a[0]);<br />
};<br />
<br />
sub::~sub()<br />
{<br />
	for (int i = 0; i < 50; i++)<br />
	{<br />
		char** A = a;<br />
		char* Ai = a[i];<br />
		char* Aii = (char *)*((int*)a[i]);<br />
<br />
		free(a[i]); // <big> crash point </big> :confused:<br />
	}<br />
};<br />
<br />
<br />
class allocater<br />
{<br />
public:<br />
	sub** subs;<br />
<br />
	allocater();<br />
	~allocater();<br />
<br />
};<br />
<br />
allocater::allocater()<br />
{<br />
	subs = (sub**) calloc(10, sizeof(subs));<br />
	int i; <br />
<br />
	for (i = 0; i < 10; i++)<br />
	{<br />
		subs[i] = new sub();<br />
	}<br />
};<br />
<br />
<br />
allocater::~allocater()<br />
{<br />
	int i; <br />
<br />
	printf("destructor allocater");<br />
<br />
	for (i = 0; i < 10; i++)<br />
	{<br />
		delete subs[i];<br />
	}<br />
};<br />
<br />
<br />
void main(int argc, char* argv[])<br />
{<br />
	allocater** a = (allocater**) calloc(10, sizeof(allocater));<br />
	int i;<br />
	<br />
	for (i = 0; i < 10; i++)<br />
	{<br />
		a[i] = new allocater();<br />
	}<br />
	<br />
	printf("allocated");<br />
<br />
<br />
//	getch();<br />
<br />
<br />
<br />
	for (i = 0; i < 10; i++)<br />
	{<br />
		delete a[i];<br />
	}<br />
<br />
<br />
	printf("freed");<br />
<br />
	getch();<br />
<br />
}<br />

Thank you everyone.. Smile | :)

If you are writing C++ code (you are using classes, which is C++ specific), why do you still want to use C functions like malloc ? Prefer the use of new and delete instead.

you are allocating 10 items (for (int i = 0; i < 10; ) and freeing 50 items (for (int i = 0; i < 50; ) and what you are trying to achieve with char* Aii = (char *)*((int*)a[i]); and you are not freeing the first dimension array "a" in sub and in main(). I prefer you to learn the concepts clearly
