Regards, BB Re: Loading JPEG or PNG images... Big Art17-Apr-03 11:36 Big Art 17-Apr-03 11:36  If you are using VC++7 (MFC) you can use the new MFC class CImage. It allows you to load and manipulate JPG, PNG, GIF, BMP formats. Very simple. Art Re: Loading JPEG or PNG images... puzzolino17-Apr-03 21:21 puzzolino 17-Apr-03 21:21  I'm not using MFC at all. I only searched through the documentation on StretchDIBits and other bitmap API functions which reads: Windows 98/Me, Windows 2000/XP: StretchDIBits has been extended to allow a JPEG or PNG image to be passed as the source image. So I was wondering how to pass a JPEG pr PNG image to this function, maybe I can read from the disk ???? Re: Loading JPEG or PNG images... Big Art18-Apr-03 6:10 Big Art 18-Apr-03 6:10  If not using MFC then I would suggest using GDI+ as was already suggested. Image::FromFile("PathToYourImage.jpg"); Art How can I to resolve the copy operation Andrea Ferraro17-Apr-03 0:01 Andrea Ferraro 17-Apr-03 0:01  Hi guys!!! In my application,I have to copy a indefined quantity of files in different folders. Each folder can contain different quantity of data ( ex: folder1:400MB,folder2:1.5GB etc..)and if necessary it'll be created a new folder during the copy. It shouldn't be a problem to implement it and check the max value for each folder,but the location of each files is collect in a table in a Database and after that it'll be necessary to update the same table with a new position of each files. I'd like to know if someone have already met a problem like this and in particular if it already exists an algorithm that permit to optimize the copy of files in order to save space. Thanks in advance for help. And I'd like to wish at all comunity GOOD EASTER!!! Andrea Screensavers and environment variables karanba16-Apr-03 23:59 karanba 16-Apr-03 23:59  Hi, everbody. I made a simple screensaver that displays a piece of text and the name of the current user. I use scrnsave.lib and use getenv() function to take the username. It works fine when I click to myscreensaver.scr file and show the name and the text but when I copied it to WINNT\system32 and select myscreensaver to be the one from display properties it opens an gives an error then close(it dose not give error also at preview mode). When I take out getenv() function it works again. So I think the problem is trying to read enviroment variables from a screen saver application. Is there a method to read enviroment variables that does not cause error and please think that how to read enviroment variables when the screen saver is password protected in NTs. karanba Re: Screensavers and environment variables Rage17-Apr-03 1:05 Rage 17-Apr-03 1:05  Have you already tried to see what the getenv() returns when your app is used as a "normal" sceensaver ? (messagebox...) ~RaGE(); Re: Screensavers and environment variables karanba17-Apr-03 21:52 karanba 17-Apr-03 21:52  Yes. It return the true value. It gives error only when I select it as my screen saver from display properties and wait to appear!? karanba Re: Screensavers and environment variables Gary R. Wheeler18-Apr-03 4:29 Gary R. Wheeler 18-Apr-03 4:29  It sounds like Windows doesn't create an environment block for screensavers when it runs them. Instead of retrieving the user's name from an environment variable, just use the API function GetUserName. Software Zen: delete this; Build date in code ? Trollslayer16-Apr-03 23:23 Trollslayer 16-Apr-03 23:23  When I do a build, it would be very useful to put hte build date/time in so when the application runs this is displayed. I can't use the file stamps because when its installed or copied these change. Any suggestions ? Thanks everyone Elaine The tigress is here Re: Build date in code ? markkuk16-Apr-03 23:30 markkuk 16-Apr-03 23:30  Use the __DATE__ and __TIME__ predefined macros. CEdit like Internet Explorer berserker_r16-Apr-03 23:04 berserker_r 16-Apr-03 23:04  When Internet Explorer create an EditControl (for example...) it doesn't create a window for each control (use Spy++ to verify that ). I need the same thing (like Flash for its editbox), how can I do that? Thanks Spin Edit control problem Jeef16-Apr-03 23:03 Jeef 16-Apr-03 23:03  Hi, I've set it's buddy to my edit control : m_spinPtSpeed.SetBuddy(GetDlgItem(IDC_SPIN_PTSPEED)); m_spinPtSpeed.SetRange(1,14) and I want to increase or decrease the value in the edit box,and when type a value into edit box,spin control can increase or decrease the current value in the editbox.So I handle the message UDN_DELTAPOS ,but the editbox's value did't change! void CCam1Set::OnDeltaposSpinPtspeed(NMHDR* pNMHDR, LRESULT* pResult) { NM_UPDOWN* pNMUpDown = (NM_UPDOWN*)pNMHDR; // TODO: Add your control notification handler code here //Get value from the edit control m_nPtSpeed=(int)GetDlgItemInt(IDC_SPIN_PTSPEED); //adjust value m_nPtSpeed=m_nPtSpeed-pNMUpDown->iDelta; //display new value SetDlgItemInt(IDC_SPIN_PTSPEED,(UINT)m_nPtSpeed,T RUE); *pResult = 0; } Can you help me solved my another problem Re: Spin Edit control problem David Crow17-Apr-03 2:40 David Crow 17-Apr-03 2:40  Is IDC_SPIN_PTSPEED mapped to a CEdit control or a CSpinButtonCtrl control? Its name implies a CSpinButtonCtrl control yet its use implies a CEdit control. Re: Spin Edit control problem Jeef17-Apr-03 4:32 Jeef 17-Apr-03 4:32  Hi DavidCrow, Thanks for your directions,I made a obvious mistake,I had test it ok!thanks! Can you help me to solve my another problem? If Can ,I will E-mail my demo project for demonstrate problem to you? Re: Spin Edit control problem David Crow17-Apr-03 4:38 David Crow 17-Apr-03 4:38  Just post the relevant code here for all to see. The more eyes, the better! Make sure you include what problem you are seeing, any error messages, what you've done so far to isolate the problem, etc. Re: Spin Edit control problem Jeef17-Apr-03 16:00 Jeef 17-Apr-03 16:00  I had post my another problem's code in last thread(there is link),I want to make the problem clear,so I made a demo project,but it's bigger than permit post in the forum .Who can offer the FTP position so can I place the demo project to be download? Or I will send to him directly help on displaying a DIB in a formview sandrineV16-Apr-03 23:00 sandrineV 16-Apr-03 23:00  Hello, I'm new to VC++ and have problems displaying a DIB in a formview. To get the device context of my formview and display in it my DIB, I use : CPaintDC dc(this); CDC* pDC = &dc; StretchDIBits( pDC->GetSafeHdc(), // dc 300, // x dest 300, // y dest int(proc->IMAGE_WIDTH), // x dest dims int(proc->IMAGE_HEIGHT), // y dest dims 0, // src x 0, // src y int(proc->IMAGE_WIDTH), // src dims int(proc->IMAGE_HEIGHT), // src dims proc->img->imageData, // array of DIB bits proc->bmi, // bitmap information DIB_RGB_COLORS, // RGB or palette indexes SRCCOPY // raster operation code ); Everything compiles fine, but when I launch my application, the picture doesn't show. Could someone tell me if I did something wrong or forgot to add something to make the picture appear (I tried to do the same with a dialog box and used the onPaint() method that was automatically called when I forced to redraw my window, but I don't know how to do that with a formview). Any help would be much needed. Thank you Re: help on displaying a DIB in a formview Chris Losinger17-Apr-03 4:04 Chris Losinger 17-Apr-03 4:04  1. where are you doing the StretchDIBBits? (OnDraw?) 2. what is the return value from Stretch*? 3. try calling GetLastError just after Stretch* 4. is the DIB valid? -c Chris Losinger Smaller Animals Software
