Thanks for the suggestion. I look into it.

I've found a mathematical formula to do this now. It assume zero mean and it is written in MatLab. sigma = 2; %The std deviation x1 = rand(1000,1); %Linear rand number between 0.0 to 1.0 x2 = rand(1000,1); z = sqrt(-2*sigma*log(x1)) * cos(2*pi*x2); the log here is ln, that is log to the base e. Now all we need is just to put it in C. Thanks to all who replied my post.

Thanks...

Sorry for the typo. The rand() just generates random numbers but not gaussian/normal distribution numbers. Chun Te

Dear all, I was wondering if there is a way to generate random gaussian numbers with Visual C++. Borland Builder has the option randg to do just this. Many many thanks Chun Te

Dear All, I'm trying to make a program that looks like installer programmes that displays one dialog box at a time. The user will then just have to chose some options and click Next to the next dialog box. Problem is I do not know where to start and how to structure the program. Can anyone please help me out here. Many many thanks in advance Chun Te, Ewe

Dear all, This would be a major easy question to most people here but How do I launch another program from my program, and to just show the other program window if the program is already launched? Just out of interest, how do I launch a seperate instance of the program instead of just showing it? Many many Thanks, Chun Te

Dear all, I was told by my professor to make a program in Perl and that is done. I now would like to intergrate it into a GUI program that will execute the Perl program. If this is possible, how do I do so? Does the user have to have a copy of Perl on his/her computer? Many thanks. Chun Te

Dear all, Correct me if I'm wrong, is memory leak due to not using delete after a new? Is there a program to check my program for memory leak? Thanks Chun Te, Ewe

Dear All, I would like to have 2 different views for a document. Each view to be display one at a time or together using a splitter window at any point of time. How best should I approach this? I'm open to any new ideas. I've just started programming and I think my question will be trivial to most of you out there. Thanks very much for taking the time to help me out Regards, Chun Te

Thanks :)

Dear all, I was wondering if I can perform DDV and DDX for dialog bars. If yes, could someone please help me out... Many Thanks Chun Te

Dear All, I hope anyone can help me out with this seeming simple problem. I've implemented a dialog bar with buttons on them which I would like to disable them from time to time. I've used m_wndDlgBar.GetDlgItem(IDC_BUTTON1)->EnableWindow(FALSE); and it wouldn't work. I even disabled it with the resource editor. Thanks very much for your precious time. Regards CT

Dear all, I would like my dialog bar to be permenantly docked to the left frame. Is there anyway to do this? Thanks. CT

Dear all, This problem of mine has been bugging me crazy. I have to load a 24bit .bmp file and convert it to a 32 bit bmp file. I've manage to load the bitmap file, display it on the screen and even made the code to make it a 32bit bitmap. The problem is to attach the modified bits to the m_bmpBitmap CBitmap object. Then I get the info of the m_bmpBitmap with the BITMAP structure. BITMAP bm; m_bmpBitmap.GetBitmap(&bm); The bm.bmBits is 0x0 which it shouldn't be. All the CreateBitmap() and GetBitmap() funtions return successful but I can't even display the image to screen and I feel it is due to bm.bmBits = 0x0. I've even tried to create a 24 bit bitmap with the same method below and it didn't work too. I would like to be able to view the image that I created and as well as to be able to save it. I welcome any new ideas on how to approach this matter. Many many thanks.
