yes u right i want functionality like screen saver

Since it is a Win32 Aplication (No MFC), there will be a message loop.
Like...
while( GetMessage( &msg, ....<br />
{<br />
TranslateMsg...<br />
DisapatchMsg...<br />
}
You have to modify it like...
<br />
SetTimer( IDT_LOCK, LOCK_TIME, 0 );<br />
while( GetMessage( &msg, ....<br />
{<br />
switch( msg.message )<br />
{<br />
case WM_LBUTTONDOWN:<br />
case WM_RBUTTONDOWN:<br />
case WM_KEYDOWN:<br />
SetTimer( IDT_LOCK, LOCK_TIME, 0 );<br />
break;<br />
}<br />
TranslateMsg...<br />
DisapatchMsg...<br />
}
And handle the WM_TIMER in the windowproc, like...
case WM_TIMER:<br />
switch( wParam )<br />
{<br />
case IDT_LOCK:<br />
KillTimer(IDT_LOCK);<br />
DialogBox( ...,IDD_PASSWORD,...<br />
SetTimer( IDT_LOCK, LOCK_TIME, 0 );<br />
break;<br />
}
Hope you got the idea...

Hi,
Am getting data continuously from the serial port(COM), i want to display the data in an multiline edit box,How to do it?
I tried one method as below but edit box flickers
void CDialog::ReadSerialData(CString sIn)
{
sIn.Replace("\r","\r\n");
m_StrCmdResp += sIn;
int nLineCount = m_CtrlCmdResp.GetLineCount();
m_CtrlCmdResp.LineScroll(nLineCount+1);
m_CtrlCmdResp.SetWindowText(m_StrCmdResp);
nLineCount = m_CtrlCmdResp.GetLineCount();
m_CtrlCmdResp.LineScroll(nLineCount+1);
if(nLineCount > MAX_RUN_BUFFERSIZE)
{
m_StrCmdResp.Delete(0,REMOVE_CHAR);
while(!(m_StrCmdResp.Find("\r\n")))
{
m_StrCmdResp.Delete(0,1);
};
}
m_StrCmdResp.FreeExtra();
}
Can we use edit box for this type of data displaying
Thanks in advance

use listbox or may be list control instead.
even i had this problem and list control solved my problem.

If you are shoing data coming back from somewhere, then an edit box is probably the wrong control to use.
I use CPPDumpCtrl - version 1.2[^] for this purpose, as you can see the data in different representations. As it is double buffered, flickering will be very low.

Well, as long as the length of the opposite corners is the same as the hole's diameter, it should still work.

But then the wumpuss could crawl in the circle sections around the edge, and then where will you be?

Good choice is CListBox or CListCtrl or even ComboBox but Editbox no.

Thanks for the help.I will try with CCtrlList.

Extract the data from a serial port, or update an edit control?

Updating in the edit control

See here. Most of the time, SetWindowText() can be used.

Hi DavidCrow,
Am using SetWindowText(), but there is flickering
Thanks

You might want to investigate SetRedraw().

You need to check the docs for xpcom. The error means that it cannot find that method, ie it's in a .lib that you haven't included.
|
|
|
|
|
Its a linker error and it seems you need to a lib file.

do you actually want to open the file to write or read something?
or are you looking to open the file in notepad automatically.
|
|
|
|
|
|
to write data into file,use
FILE * fp;
fp=fopen("filename.txt","w");
fprintf("hello");
fclose(fp);
to open the file automatically, use
system("notepad filename.txt");
