0. Split your array into four parts (use the pointer to determine where you're doing the split, don't make another copy of the data) 1. Create worker threads to sum each with their portion (pointer to the beginning and size). 2. Wait for all threads to finish, sum their results. If this was a program that needed to do this over and over again, I'd also create a "thread pool" that is precreated. Creating threads on the fly is actually a pretty slow process, you want to do it sparingly.

You may either want to use the circular buffer for holding the pointers of the actual strings or, more likely, for holding the strings themselves. In the first case coding is pretty straightforward (you may use Wikipedia's circular buffe[^]r page for inception). On the other hand, the second case is bit more complex, since you have to explicitely manage blocks of bytes (the strings) in the circular buffer. THESE PEOPLE REALLY BOTHER ME!!

This is a good question because I'm not sure any of those really describes Windows messaging well. Sort of interesting given that it's the primary means of communication in the Windows desktop environment. I guess the rational behind this is that you can't really pass along data across messages, you can pass commands/messages and references. I used to use messages a lot within an application to communicate but it's a bit different when dealing internal to an application because you can pass data by reference easily. Externally, you can only do that if the data is in a place that is accessible to both applications or meets certain restrictions (as described here[^]).

Quote: _snwprintf_s and wprintf are not identifier. If you look at the tchar.h include[^], it has the definitions for those. If you include that file and still get errors in regards to wprintf and the other call, do note that they're enclosed in an #ifdef statement that requires the project to be compiled using _UNICODE.

Thanks a lot!!!

It looks[^] the official library is DbgHelp, and they do actually provide overlapping functionality. THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

Thanks Superman! The difficult we do right away... ...the impossible takes slightly longer.

You haven't asked for help, you asked for a full solution. If you want help, then you first need to do as much as possible by yourself, up to the point where you don't know how to proceed. Then tell us why you can't proceed and what, precisely, it is that you don't understand or don't know how to solve. There's no point for us to provide a full fledged answer if we don't know what you already know - we might just be wasting our time telling you what you already know! You may be unsure on how to start, maybe you believe if your design isn't perfect right from the start then you will ultimately fail. But that is not how software development works: software development never starts with a perfect design! Instead you start with what you think works best, and go on until you realize that you can't go on, or some detalis of your design are impractical. Then, based on what you've just learned, you correct your design. If all else fails, start new from scratch. GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them.

No worries Richard, and please note that I do thank you for your overall support. Cheers

C has a powerful printf[^] function to format variables... Skipper: We'll fix it. Alex: Fix it? How you gonna fix this? Skipper: Grit, spit and a whole lotta duct tape.

I would design the UI for such a requirement by embedding the radio button is some sort of a list. Here is an example - CQuickList[^] «_Superman_»  _I love work. It gives me something to do between weekends. _Microsoft MVP (Visual C++) (October 2009 - September 2013) Polymorphism in C

Hi Richard, First and foremost, sincere apologies for a naivety mainly attributable to inexperience Yet. I acknowledge that the code posted is perfectly fine. While adapting to my needs, performing the loop before the below piece of code has resulted in blank "Ret" columns, confused me, and triggered some skepticism. sda->Fill(dbdataset); Now all look fine, and I'd like to thank you very much for your assistance. I spent the weekend on this mater whereas it took you barely few minutes from your side to bring a concrete solution. Hence I am indeed impressed, and hope to become a day a c++ pundit like you so as to give back by helping others on forums too. Cheers Member 11230372

You could use one of the STL collection classes, such as array or vector. See http://msdn.microsoft.com/en-us/library/a7tkse1h(v=vs.100).aspx[^] for details.

No problem , I will try some option too...

That's the space for the icon, nothing you can do about it. You could use an image that just contains a line so it extends to the actual tree item.

The graphic is simply used as a diagram of the antenna that pictures the dimensions needed for the equations. I do mean that values are plugged into each field six times or so before the program hangs using the mouse to select each field. So, if the user does a lot of playing around with different dimensions and frequencies during the same session and uses the mouse to change from one field to another the program might hang.

Good luck with that. I've just learned it all by trial and error over the years. MSDN does have a reference, which is fairly complete. For the missing pieces, empirical testing is your friend.
