i have done the same for temporary. i am drawing rect with background color and then draws the lines.
so like that every time i first draw blank rect and then draw a lines on it.

it helps me for now.

GetDlgItem(IDC_STATICDISPLAY)->Invalidate( true );

THIS IS NOT WORKING. its still not clear the old drawing.

thanks for the solution.

by doing

bReadRC = ReadFile(handle_comm, &sBuffer, 1, &iBytesRead, NULL);

reading only one byte helps me to do it faster.

this

bReadRC = ReadFile(handle_comm, &sBuffer, 255, &iBytesRead, NULL);

readfile function is already giving me one by one byte.

i am not getting whole packet at once . i am getting byte by byte.

so should i replace 255 to 1 ?

BOOL bReadRC;
DWORD iBytesRead;
DWORD dwError;
unsigned char sBuffer[255];
char sMsg[512];

if(iVal == 0)
{
start = clock();
}

memset(sBuffer,0,sizeof(sBuffer));
bReadRC = ReadFile(handle_comm, &sBuffer, 255, &iBytesRead, NULL);

if (bReadRC && iBytesRead > 0)
{
itoa(sBuffer[iVal],sMsg,10);;
//printf("\n%d::%s",iVal,sMsg);
CString temp(sMsg);
iBuffer[iVal] = _wtoi(temp);
//printf("\n>>%d,",iBuffer[iVal]);
iVal++;

if(iVal == PACKET_SIZE)
{
iVal = 0;
//printf("\n");

unsigned int iTimeDiff = clock()-start;
printf("\niTimeDiff :: %d",iTimeDiff);
}
}

this is my code i have done reading like this

i am not telling you to do it for me.
as i am working on serial communication and as i am seeing data receiving is faster in termite but in my application i am getting 1 packet at 3 second. so i am asking for termite code or you can also help me in other ways.

i just want to read data faster.
any help will be helpfull to me
