Rolling Display with Editbox
-
The short answer is: call SetWindowText for the edit box using a rolling buffer. :)

What's a rolling display ? a marquee ? For an edit box, I would generate a string with appropriate spaces and "offset" with a timer control.

I can make the text keep moving from right to left, but the text will stop at the end. Is it possible to make the text disappeared at the end of the display? How to do this? Please help!
Q&D: add spaces to the end of the text that will "push" the printable characters off the end of the control. Peace!

A silly example:
// globals or class members, whatever you like...
TCHAR szText[]= _T("Come in here, Dear boy, have a cigar. You're gonna go far, You're gonna fly high ");
const int DISPLAYSIZE=10;and then
void RollText()
{
TCHAR szBuff[DISPLAYSIZE+1];
static int iStart = 0;
static int LEN = _tcslen(szText);szBuff[DISPLAYSIZE] = _T('\0');
int i;
for (i=0; i<DISPLAYSIZE; i++)
{
szBuff[i] = szText[(iStart+i) % LEN];
}SetDlgItemText(IDC_ROLLEDIT, szBuff);
iStart++;
iStart %= LEN;
}Each time is called,
RollTextroll the text a character on the left in the edit box. BTW code has mere illustrative purposes: you should code it better. :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Of course (but I'll bet no money)! :laugh:
