Hello Guys,

I was looking for a vertical text scroll engine or lib or simple sample code like u see in the about box of keygen or nfo viewer. I found diablo2oo2's scroll text lib, but it works for text horizontally. I tried downloaded some sample codes of keygen, but they include all extra things and the code is too complex to look at to figure out just how it making the text scroll vertical moving bottom-to-top n top-to-button. Can any one just put a small easy to understand sample code or hints without using any bitmap or effects. Juts simply a dialog box n text scrolling..

Thanks in advance...

// Setup scroller
			int nLines = 0;
			LPSTR lpszLine = lpszAboutText;
			while(*lpszLine){
				if(*lpszLine == '\n') nLines++;
				lpszLine++;
			}
			SIZE szAboutText;			HDC hdc = GetDC(hWnd);
			hdcText = CreateCompatibleDC(hdc);
			ndcText = SaveDC(hdcText);			HFONT hfAbout = CreateFontIndirectA(&lfVerdana);
			SelectObject(hdcText, hfAbout);
			GetTextExtentPoint32A(hdcText, lpszAboutText, strlen(lpszAboutText), &szAboutText);
			CopyRect(&rcText, &rcClient);
			rcText.bottom += (szAboutText.cy * nLines);
			hbmText = CreateCompatibleBitmap(hdc, rcText.right, rcText.bottom);
			SelectObject(hdcText, hbmText);
			ReleaseDC(hWnd, hdc);			SetBkMode(hdcText, TRANSPARENT);
			SetTextColor(hdcText, RGB(255, 255, 255));
			rcText.top += rcClient.bottom;
			DrawTextA(hdcText, lpszAboutText, strlen(lpszAboutText), &rcText, DT_CENTER);
			DeleteObject(hfAbout);			nOffset = 0; nOffsetMax = rcText.bottom;
			SetTimer(hWnd, 1, 60, NULL);

Cheers,

Please speak any more suggestions if anyone still have to say on this, though I didn't got the time to try this code yet.. I would like to know more on this if any. Will ask here for improvements later after trying it :)

Thanx

Ok, here is a bit "purified" code, which of course is not mine, but I thought it was needless to say, Mate ... my coding skills sux ... :(

Cheers,

Seems you got carried away a little with the purification there :sweat:

I can only agree, but sorry, cant show all ... thats why I put purification in quotation marks ... :^

I m running XpSp3 and using VC 6.0 . How do i make use of gdiplus. I tried downloading the sdk, it contains a dll named gdiplus.dll. Someone said that xp already comes with gdiplus...<br /><br />but my program just donno where to find include <gdiplus.h>.

How do i setup and configure gdiplus for VC 6 ?

(Sorry, if my question looks silly, I m just new to gdi+)

My first guess would be that VC6 doesn't have the gdiplus headers at all. It's from before 2000, mind you and GDI Plus came with XP or something.

You might wanna switch to a more recent compiler (VS 2010 just got released) :geek:

@SSlEVIN : Your code is not working.
