And what has this to do with my suggestions to the OP? I must get a clever new signature for 2011.

Are you sure you are on the right forum? Best wishes, Navaneeth

As the others have mentioned keeping the file open will be faster but second will be more secure if something goes wrong. You might be able to get some of the the performance of keeping the file open with opening and closing it every time by opening the file unbuffered. This[^] has got loads of useful info about the pain in the neck this is to sector align buffers if you're on windows. You can do something similar on Linux with the open() system call. It all depends on how much money's involved if something goes wrong and how much the customer is willing to pay for security. Another solution might be to open and close the file every transaction and make sure the powers that be spend the money they'd have spent on you engineering a software solution on more memory for the server to reduce the impact of repeated opens and closes. Another option might be to try the double open trick that used to work years ago on some Unixen and DOS. You'll have to see if this does any good, I've not used it on any version of windows since Windows '95. What you do is open the file when the program starts. This makes a second opening really quick when you write a transaction. when you finish writing the transaction you close the file which flushes it to disk. Finally when the program terminates you close the original opening. Cheers, Ash

Basically your question is, if the operating system reuses socket handles? Yes, I would guess that with a long running server application there is no other way for the operating system. On Windows this definitely happens, see Winsock Programmer's FAQ[^]. In my networking applications I separate session/user handling from low-level networking, which means every user gets a unique ID assigned. There are many ways to create an ID, for example use the current UTC time paired with a random value. Alternatively, if you just need an unique internal reference, you could use this pointer of your C++ object. Not sure if this answered your question?

thanks, what you said helps Simon

Do you want to retouch a bitmap at your program? Of one Essence is the human race thus has Creation put the base One Limb impacted is sufficient For all Others to feel the Mace (Saadi )

simon alec smith wrote: can anybody explain maybe why this is not working. Why what isn't working? You can load any file type from resources - this page[^] describes the process reasonably well under the 'Creating a Resource List' heading: call FindResource or FindResourceEx with the resource name to get the resource handle; call LoadResource with the resource handle to get the global handle; call LockResource with the global handle to get a pointer to the resource data. I've done this several times - it works really well. Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

simon alec smith wrote: I now wish to use the scanned image for 3d graphics but the rendering is to slow How are you rendering the image in 3d? The usual use for 2d images in 3d programming is as texture maps or mipmaps, with OpenGL or Direct3D - they definitely get rendered quickly enough there, or there would be no 3D games on PCs!!!

thanks

Having a hard time following the logic on your math. You're multiplying the tangent by 12, which appears to be the length of the hypotenuse since you using it later in what looks like the Pythagorean theorem. Since tangent has no relation to the hypotenuse, I'm not sure why you're doing that. (tangent = opposite / adjacent). I'm not sure what you're trying to do, but if it's drawing "spokes" (like a wagon wheel) from the origin to various angles, then why wouldn't you just use something like: x = length * cos(currentAngle) y = length * sin(currentAngle) And sweep thru the angles you want to cover? I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins

One thousand sockets doesn't sounds like impossible. I guess you will hit limitations somewhere else, for example traffic limitation of your internet provider or performance bottlenecks in your server (who has to handle and distribute events to all clients).

In addition to DavidCrow's reply... simon alec smith wrote: widthRatio = Rect.Width() / 756; then * the x posistion by the widthRatio When working with integers like this, you can often rearrange the calculation to avoid getting the 0. Do the multiply first, then the divide. This way you can avoid floating point types which can give better performance in certain situations. Of course, if you need the ratio variable in other places, then you'll need to make sure you do a floating point calculation as DavidCrow showed. Mark Mark Salsbery Microsoft MVP - Visual C++ :java:
