But you will not get the expected result if you write it in OnPaint().
You need a timer to get the result.

Ok. I know I don't need to tell you how to use a timer to do the text scrolling... Smile | :)

I just mention about the timer, because according to me your code was so simple, and for a beginner it will not be enough to reach the result as you said that you would write it in the paint handler.

Yeap you are write, it will very difficult for grasp the concept OnPaint Handller. also by carefull study, it very difficuly to see moving text at In OnPaint handller as screen have to be repainted for Printing text!

You can't go Sleeping all over the place. The application will not be responsive and repaint itself if its Sleeping instead of running a message pump. 9/10 Sleep calls I see shouldn't be there.

SYSTEMTIME sysTime;
GetSystemTime (&sysTime);
CString s;
s.Format("%u-%u-%u",sysTime.wYear ,sysTime.wMonth ,sysTime.wDay);
    // String s has the date in your format

Somethings seem HARD to do, until we know how to do them.

Another way, I guess:

CTime sysTime = CTime::GetCurrentTime();
Cstring m_cdate;
m_cdate.Format("%d/%d/%d",sysTime.GetYear(),sysTime.GetMonth(),sysTime.GetDay());

Should be:

Use AfxRegisterWndClass() or AfxRegisterClass().

ADO - UPDATE -newbie

Hi again i wrote this function to update a record in access using ADO but i get an error can anyone find out whats wrong

int valField5;
int valField2;
double valField4;
string command;
_bstr_t strtest=valField4;

pCommand->ActiveConnection = m_pConn;//previously opened connection
command="UPDATE tblDictionary SET Spam="+valField2;
command+=",Pos="+strtest;//when i write pos="valField4; i get compilation error
command+=",app="+valField5;
command+=" WHERE token='"+ token;
command+="'";

_bstr_t strSQLstatment=command.c_str();
variant_t vntRecordAffected;
m_pConn->Execute(strSQLstatment,&vntRecordAffected,adCmdText);

It compiles ok but then i get an error

Error:Θï█
Press any key to continue

i know my question is not very clear but if u can see anything that might cause the error pls let me know.

is it because i'm not giving the values for all columns of the record
in the database table i have
token text
Spam number
Ham number
Pos number(with decimal)
app number
i only try to update some values is that correct

thanks again

Have you tried:

Double Buffering?

Sarath C5-Jun-06 1:05

Sarath C

5-Jun-06 1:05

For drawing, we are using double buffering. i.e we will create a new DC and draw into it and finally bitblt to the screen.
Why we are not getting the flickering On BitBlt ing the memory DC?

Can we adopt any other method to avoid flickering.

Sa^Rath.

Nishad S5-Jun-06 1:37

When you are using double buffering method, the drawings are done in the memory DC, which is not seen to us. Then you BitBlt it to the screen DC. The BitBlt is a very fast operation and there is no erasing. Means the content in the memory DC is overwritten to existing screen content. So you will see a full image after the BitBlt.
But if you are drawing directly to the screen, for example, you may have to clear the screen and draw something and then draw something over it, etc. As all these operations are visible to us, we feel it as flickering. But in the case of double buffering, these are done in the memory DC, which is hidden from us, and the final result is shown immediately, replacing the existing one.

I think you got it. Smile | :)

Hello SaRath,

Yes, I agree with NS17. When you are doing bitblt your OS (as it is system call) will do mass edit of pixel. But when you do this for every pixel your function is call stack process is do and take some time. While for bitblt all pixel changes injust one call.
