It very hard to guess about problem, you need to show some code for that.

This function is written in ping class.....
void CPingThread::LogMessage(CString& logmsg)
{
if (m_pLogWnd)
{
ping_pasiin_val SP_obj_val;
SP_obj_val.index = ping_int;
SP_obj_val.url = ping_str;
m_pLogWnd->SendMessage(PINGMSG, (WPARAM)(CString*)&logmsg, (LPARAM)(&SP_obj_val));
}
}
n this is written in class used for clistctrl....
LRESULT CHttp::OnPingLogMessage(WPARAM wparam, LPARAM lparam)
{
CString* pLogMessage = (CString*) wparam;
struct recv_val* pStruct = (recv_val*)(LPVOID)lparam;
int u = pStruct->Recv_index;
CString result_val = *pLogMessage;
if(result_val.Find("-") <= -1)
{
m_Main_List.SetItemText(u,7,*pLogMessage);
}
}

I didnt find the code that sets the value in pStruct->Recv_index
you are setting the value only to
SP_obj_val.index
SP_obj_val.url
in the LogMessage function. Or did you forget to paste the code here?

There is no way, I could know that ping_int is different all the time ,but in OnPingLogMessage you are getting same value.
Try debugging , if value you are setting while sending the message is different.
ps. Neha , you are quite familiar with CP now. Then also, you are no following posting guidelines[^].

There are multiple places that you could put breakpoints, or at least add TRACE() statements, to confirm the values are what you expect.
void CPingThread::LogMessage(CString& logmsg)
{
TRACE(%s\n", logmsg);
if (m_pLogWnd)
{
ping_pasiin_val SP_obj_val;
TRACE(%d\n", ping_int);
SP_obj_val.index = ping_int;
TRACE(%s\n", ping_str);
SP_obj_val.url = ping_str;
LRESULT lRes = m_pLogWnd->SendMessage(PINGMSG, (WPARAM)(CString*)&logmsg, (LPARAM)(&SP_obj_val));
TRACE(%d\n", lRes);
}
}
LRESULT CHttp::OnPingLogMessage(WPARAM wparam, LPARAM lparam)
{
CString* pLogMessage = (CString *) wparam;
TRACE(%s\n", *pLogMessage);
struct recv_val* pStruct = (recv_val *)(LPVOID)lparam;
int u = pStruct->Recv_index;
TRACE(%d\n", u);
CString result_val = *pLogMessage;
if(result_val.Find("-") <= -1)
{
BOOL b = m_Main_List.SetItemText(u, 7, *pLogMessage);
TRACE(%d\n", b);
return 1;
}
return 0;
}

Hi,
Could you please let me know, if we have to extract multiple cab files do we have to create those many instances of CExtract class? and make corresponding entries (e.g ID_CAB_TEST) in resource file?
We have many cab files to extract and at runtime we are reading the names of the files. We wont have the list of all cab files before compilation to add in the resource file.
Please let me know if it is possible to extract multiple cab files without making their entries in the resource file. If yes, how.
Regards,
Rupal.

Hi all,
I'm trying to append data to the end of a file. The problem is that when I call the WriteFile function (it return 1), but none of the data gets appended. The buffer isn't empty. What could be the problem ???
I have used GetLastError, and the function returns 0 ... so 
This is what I have done so far:
#define BUFF_SIZE 4000
char buffer[BUFF_SIZE];
Handle hFile = CreateFile(attTMPFName,
GENERIC_WRITE,
0,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL);
if (WriteFile(hFile ,buffer,BUFF_SIZE,&dwBytesWritten,NULL))
{
...
Many thanx in advance.
Regards,

call SetFilePointer() after the CreateFile()
::SetFilePointer( hFile, 0 , NULL, FILE_END );// Moves the pointer to the end of file.

but I cannot find where do you move the write pointer (see SetFilePointer on MSDN) at the end of the file, do you?

Ok, you are reading the buffer from same file you opened and appending it with same buffer.
But, you have mentioned GENERIC_WRITE flag. Then how it is possible ?

Sorry prasad_som, I didn't explain properly.
I use bufferA and HandleA to open / read the first file (lets call it file1.txt).
Then I use bufferB and HandleB to open / write the second file (lets call it file2.txt).
So basically I'm appending the contents of file2 to file1.
Makes sense.
The SetFilePointer worked.
The other question I wanted to ask was: how big may ones buffer be? When writing / reading files
Many Thanx

Maximum DWORD can hold. ie. 4294967296.

In theory. In reality, it would likely be less than 2GB.

There's no way a buffer can be 4GB (which is the question I was answering). Under normal circumstances, Windows only gives each process 2GB, and not all of that is available, which is why I said "less than."

Its just addition to existing post, in lst post[^] its accumulated writing, which is most of it is present in my previous post. Which I've deleted.

, No , you dont. I'm asking you to delete yours(if you feel), I feel, I've created unnecessarily multiple posts.

Yes, mentioned figure goes to 4GB.
Where as, only 2 GB address space will beavailabl for program out of 4GB virtual memory.

I think , this will be not case with 64-bit systems though.

Why confuse the issue with matters that were not even mentioned? Keep it simple.

True. I've just added one more thing.
[OT] I wonder, something is messed with posting, when i tried to post, its getting duplicated, and when tried to delete one of them, both are deleted.

strlen should give you correct result. Check lpNumberOfBytesWritten, for checking number of bytes written.

. Can you paste the code here? Did you check the return value of the strlen function?
