Yes, you can. Look at LVITEM-->iSubItem. Mention subitem index there(1 based). If its set 0 , LVITEM refers to item.

List ctrl rows displaying same value......

Have a look at GetIfEntry(), and the Win32_NetworkAdapter WMI class.

Hi All,

Actually i m trying to ping two sites together and want to display its result in a list control rows.For doing this i have made a class derived from CWinThread Class and then posting the result using SendMessage Function to the list control class which is derieved from CFormView class...

My problem is that all rows are displaying same value........

how to solve this problem

Thanks in advance

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[^].

Extracting multiple cab files

29-Mar-07 3:28

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.

WriteFile Issue

Programm3r29-Mar-07 0:14

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 Confused | :confused:

This is what I have done so far:

#define BUFF_SIZE 4000
char buffer[BUFF_SIZE];
/*
I did a CreateFile and ReadFile, to get data into the buffer
*/
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.

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

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."
