oh.. it makes the apps lag only.. the system doesnt lag

good

Hi, I've search throughout the net, cant find any solution. Hope someone able to help me. My apps had a panel which can draw many rect. The app can be moved by draggin left/right using mouse. Whenever i moved the panel, it'll try to move all the rectangle to top/bottom/left/right following the mouse motion. When the mouse move, it will force the rectangle to be redraw. My app become laggy whenever i use .DrawText to a multiple line of text inside the rectangle. I have around 80++ rect which used .DrawText to display the text on each rect. I've tested, if the text is only 1 short words without /r/n (one line), then it will display nicely without laggy. eg: Alice But if the text is in multiline (about 4~5 lines) i tried to run .DrawText, it makes my apps lagg. eg: Alice in wonderland Any idea ?? The command i used : dc.DrawText(strDraw, rcText, DT_LEFT | DT_WORD_ELLIPSIS); Regards, KH

oh i'm using the pDC to draw the rectangle. That one I'm just testing out with the link given by Chandrasekharanp I'm taking pDC out now and try your method. But after i put below code, and execute it then the button went dissapear void CCustomEdit::PreSubclassWindow() { CRect rcItem; this->GetClientRect(&rcItem); CRgn rgn; rgn.CreateRoundRectRgn(rcItem.left, rcItem.top, rcItem.right, rcItem.bottom, 50, 50); SetWindowRgn( (HRGN)rgn.Detach(), TRUE ); CEdit::PreSubclassWindow(); }

good

what place should i place the CreateRoundRectRgn() and SetWindowRgn() ? I've try below code but it seems like the EditBox keep on blinking CRect rcItem; CDC* pDC=this->GetDC(); this->GetClientRect(&rcItem); CRgn rgn; rgn.CreateRoundRectRgn(rcItem.left, rcItem.top, rcItem.right, rcItem.bottom, 50, 50); SetWindowRgn( (HRGN)rgn.Detach(), TRUE ); Thanks, KarHong

Hi, I'm able to set the text and the background color of the text for Status bar, but I'm not able to set the color for the 'seperator' of the status bar. I have 3 column on the status bar, each of the text and background I'm able to set it but have no luck on the 'seperator' I've done it by creating a custom status bar inherited from CStatusBar By drawing it on DrawItem CODE: CDC oDC; CDC* pdc = CDC::FromHandle(pDIS->hDC); pdc->FillSolidRect(&pDIS->rcItem, RGB(255,255,255)); oDC.Attach(pDIS->hDC); oDC.SetTextColor(RGB(255,0,0)); oDC.SetBkColor(pDIS->itemData); pDIS->rcItem.left += 2; oDC.DrawText(_T("Test"),&pDIS->rcItem,DT_LEFT); oDC.Detach(); Any ways to do this? I wanted to change the whole status bar into white color RGB(255,255,255) Any help would be appreciated. KH
