I`m curious why sometimes my antivirus sees my programs as threats for my computer. I thin kit has to do with memory allocations.
-does anyone know why and how to avoid something like that?
-why would otherwise the reason be?
Traditional detection of viruses have been fingerprint based. However, with polymorphic and metamorphic viruses and the sheer increase in new viruses, AV vendors have started moving towards behavior-based detection. Your program may be targeted because it exhibits 'virus-like' behavior. For instance, your program may be attempting to read files from disk that it may not have permissions to, modifying other executables or important system settings present on the system, automatically sending email or starting network traffic, or changing system startup actions in abnormal volumes.
Unfortunately, how to work around a specific vendor's detection is a bit of a black-box. I would check if your AV product has a whitelisting mechanism.

Everytime i run my software i can access from winhex the memory and read the information my software pass through memory like emails, phones, etc. Is there any way to secure that or at least to remove this information from memory ?
A program written to use the debug API, run under the authority of someone who can run a debug API capable app, cannot be protected against. If it could, you couldn't debug your software.
There is a privilege model:

But if someone is running with sufficient privileges to run WinHex and look at that information, then no. There's no way to exempt your program from inspection from those who have the privileges.

I was wondering what kind of front end is used for trading applications. Coming from a quant background, I was always only concerned with research and back end of the application but am at a total loss when it comes to front end/ gui. Most of my coding has been done in c++ and I am using just a config file to pass parameters.
Now it turns out due to regulatory reasons, this might not suffice. I need to have a front end which can start/ stop the strategy, change parameters and fetch order and trade history. So question boils down to this, How can I create a simple ui which can sit on another machine, communicate with the colocated machine and do all this.
Initially I thought of using web/javascript but not much is out there regarding this. Qt is another option but I suspect it will require substantial rewrite of the code and learning.
What is the preferred front end for medium to high frequency trading applications which have the core strategy running in c++?
Coming from the industry, I can tell you with certainty: Anything goes. I have worked on trading application frontends using MFC, QT, Forms, WPF. Java is quite popular too, as are homegrown abominations. One non-obvious way to communicate with the colocated machine is Citrix or Remote Desktop.
You do need to make sure that you have well defined behavior in case the client crashes, server crashes, connection between them freezes/gets lost, connection to the market gets lost, connection comes back, etc. Tell the trader how it will react in these situations, in advance. If it doesn't make sense, the trader won't use your application.
Further details depend on many variables. Are you an ISV, or is it an in-house application? Are you working in an arcade? Which markets are you connecting to? Does your hosted co-lo environment have some special rules in regards to what can run there?

I need some unbiased views from experts. I bought BobCAD a couple months ago. It did run fine while evaluating and also after installation. Now, after some use it starts crashing with multiple "null Pointer" exceptions on closing the simulation mode.
Tech support is telling me that it is the graphic card that behaves (I quote:) "unpredictable". They say an integrated graphic card is only good for word and internet browsing.
However BobCad once run fine, I can perfectly play games, use CAD or other applications on my computer without crashing it. This leads me to having a hard time to believe this. BobCad does not use a lot of resources contrary to what they claim. There is no lagging or signs of useng my computer at the limit of what it is capable of.
From what I know you do not program the graphic card directly anymore - and certainly not in a CAM application, so those problems with graphic cards should be gone.
From what I see BobCad is a WPF application presumably written in C++
Please tell me, are they right? Is my suspicion of them not being very competent wrong?
Help me out with your experiences.
Best Regards
Leo
A expensive dedicated graphic card is usually better than an integrated,
but that doesn´t means that integrated ones can´t do any real work.
Gc´s are directly programmed, even today (usage is even rising).
But, probably not in a WPF application...
Anyway, that all is no excuse for Nullpointerexceptions delivered to the user.
That´s simply a programming error, doesnt´t matter what your Gc is capable of.
If the program says "The Gc is too weak" it´s one thing, but crashing is inacceptable.
(And, incomptent support people are nothing unusual, sadly.)

Basically what I'm wondering is, how could you get like a list of all mobs, champions their hp, mana etc with programming? I know this is possible because it has been done before but I just can't see how you would be able to do this. Is looking in the assembler code necessary or can you do it in some other way? I'm mostly wondering about the theory behind it. (Using C++ if that helps anything at all)
Such things are usually done using crawling (e.g. retrieving the data from the web pages provided by Riot Games; might be partially outdated) or using reverse engineering to get this data from the game client's files (might not contain everything). In either way you'd get datasets which you'll have to read or interpret (look for values or replicate the way the game client reads and interprets the data).
I'm not sure whether there are some tools or APIs released somewhere, at least I haven't heard of anything officially supported or endorsed; most of this is essentially in a gray zone usage wise.

I work on embedded systems with limited memory and throughput. Making a system more robust requires more memory, and time on the processor. I like the idea of the Chaos Monkey to figure out if your system is fault tolerant, however with limited resources I'm not sure how feasible it is to just keep adding code to it. Are there certain design considerations whether in the architecture or otherwise that would improve the fault handling capabilities, without necessarily adding "more code" to a system?
One way I have seen to help in preventing writing an if then statement in c (or c++) that assigns rather then compares a static value, recommends writing that on the left hand side of the comparison, this way if you try to assign your variable to say the number 5, things will complain and you're likely to find any issues right away.
Are there Architectural or Design decisions that can be made early on that prevent possible redundancy/reliability issues in a similar way?
Yes many other techniques can be used. You'd do well to purchase and read "Code Complete".
