Gauge controls for MFC Andre xxxxxxx6-Feb-06 7:18 Andre xxxxxxx 6-Feb-06 7:18  I am looking for some gauge controls like the Dundas gauges, but for MFC and not .NET. Commercial is ok, but as always free would be better Thanks Downloading a File using Win32/C Mike Doner6-Feb-06 4:48 Mike Doner 6-Feb-06 4:48  Hi All, I remember seeing a call that would allow you to download a file via a url in MSDN, I can't for the life of me, remember what it was called. Anybody know? Thanks. Mike Re: Downloading a File using Win32/C James R. Twine6-Feb-06 4:57 James R. Twine 6-Feb-06 4:57     I think URLDownloadToCacheFile(...) and URLDownloadToFile(...) are what you are looking for.  There is an article here on CP that demonstrates at least one of those functions.    Peace! -=- James If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Sometimes I show the modeless dialog above parent dialog to display some progress of worker thread. Progress window can be currently moved along the screen. How to make it clipped by parent dialog ? (Something like a view window in the MDI Frame) Thank you! rrrado Re: Modeless dialog clipped by it's parent dialog James R. Twine6-Feb-06 4:39 James R. Twine 6-Feb-06 4:39     By doing so you would be eliminating one of the features of a modeless dialog in this context - why not just show the progress on the underlying dialog and save yourself the trouble?    Anyway, you can handle WM_MOVE on the modeless dialog, and constrain its movement to the bounds of the parent window.  This will not really clip the modeless dialog, but that too is not such a good idea because you would be allowing the user to effectively hide the modeless window, again eliminating one of the basic features of a modeless dialog.    Peace! -=- James If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Re: Modeless dialog clipped by it's parent dialog rrrado6-Feb-06 4:53 rrrado 6-Feb-06 4:53  I cannot show it in underlying window because it contains big area which is useless when not working and there is not enough room in parent window for this. I'm handling parent movement exactly as you've wrote but it allows to move it for example above right edge of parent and then move parent together with progress to right edge of desktop so progress will be hidden. I don't want to handle all such situations including minimizing window, etc. There must be some easier sulution and I want to know it For example WinRar shows progress this way and it looks good rrrado Re: Modeless dialog clipped by it's parent dialog Maximilien6-Feb-06 7:05 Maximilien 6-Feb-06 7:05  please don't ... me think it goes against good normal Microsoft's UI behaviour .. BUT ... you could do something different ... if your progress dialog is modeless and does not really show information ( apart from the progree ); add a status bar to your dialog application and and display the progress in there insted on a popup modeless dialog.

It's not for fractional numbers, it's the range. Remember that a time_t is (usually) a typedef'd long (not unsigned). It's possible to get a difference between two values that overflows the range of a long, necessitating a larger data type - a double. Since the typedef can change, you can't just use an unsigned long for the return value - it may give different answers if a larger data type is used for time_t. The only practical solution is to use the largest datatype possible.

Twine6-Feb-06 3:58 James R. Twine 6-Feb-06 3:58     The quick-n-dirty way is to call GetTickCount() before and after and compare the difference.  However, the resolution of that function is not usually 1ms.  For example, it is possible to call the function before and after a method that takes 5ms and get back a difference of 0ms one time and 15ms the next.    If you need better accuracy, I would suggest a multimedia timer or something similar.    it MIGHT help to call Sleep() right before calling into the function if you think the function executes is less than a quantum, to try to avoid a context switch while the function is executing.    Peace! -=- James If you think it costs a lot to do it right, just wait until you find out how much it costs to do it wrong!

Re: Timer normanS6-Feb-06 18:20 normanS 6-Feb-06 18:20  If you're doing it in the development environment, use the profiler. If you can get it to work (I remember having some "issues"), it is much easier and more accurate than using GetTickCount, etc. Of course, in production software this is not available. ODE equation solver Ming Luo6-Feb-06 3:25 Ming Luo 6-Feb-06 3:25  Hi all: Is there any clues to solve the ordinary differential equations in C++??? Expecially for stiff equations. If there is any code available?? Thanks in advance Asura Re: ODE equation solver minox6-Feb-06 8:11 minox 6-Feb-06 8:11  You can purchase "Numerical recipes in C", second edition, Cambridge University press. It contains C code for the most common ODE solvers (runge kunta 4 and 5 order, Ridchardson, Rosenbrock, Adams-Bashforth, and provide solid background on the math and tricks behind. Those methods covers borh normal and stiff ODE. Unfortunatly, they give no code for Gear like methods, wich, to my understanding, are becoming very popular to solve stiff ODE. The other drawback is the the C coding style. I have no issue doing maths in pure C in a C++ program, as it allow more time efficient code, but the C style in the book is not very nice and readable. I advice to use it as a canvas then rewrite things yourself. There are other sources for C or C++ ODE solvers on the net. Most are in FORTRAN, not alwways well documented, and reverse engenering to get it in C or C++ is tough. Take a look at www.gnu.org/software/gsl, it's a mathematical librairy in the GNU project and contains sources for many ODE. I'm looking myself for a good C or C++ GEAR code, so if you find any, let me know printing with MFC vikas amin6-Feb-06 2:32 vikas amin 6-Feb-06 2:32  Pls dont send me any link i have gone through them , I have an MFC Application . My problem is simple that i have a document from which in need to print . but when i print the font size change gets small which is also visisble in the printpriview . is there any simple way by which i can have the same printout as it is visible in the frame window thanx Vikas Amin Embin Technology Bombay
