• Should I use a global var or call the function every time? C++

  - by extintor

  Im using: bool GetOS(LPTSTR pszOS) { OSVERSIONINFOEX osve; BOOL bOsVersionInfoEx; ZeroMemory(&osve, sizeof(OSVERSIONINFOEX)); osve.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX); if( !(bOsVersionInfoEx = GetVersionEx ((OSVERSIONINFO *) &osve)) ) return false; TCHAR buf[80]; StringCchPrintf( buf, 80, TEXT("%u.%u.%u.%u"), osve.dwPlatformId, osve.dwMajorVersion, osve.dwMinorVersion, osve.dwBuildNumber); StringCchCat(pszOS, BUFSIZE, buf); return true; } to get the windows version, and I am planning to use pszOS every a few minutes, Should I use pszOS as a global var or call GetOS() every time? What's the best option from a performance point of view.

• Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?

  - by Rahat

  Is there any way to capture the time interval between mouse wheel scroll start and stop? Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel. I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. Any advice will be appreciated.

• Where to find a unique session ID at design time in .Net WinForms.

  - by Jules

  I've created a custom clipboard because it's not possible to make my whole class map serializable - which is a requirement for the windows clipboard. However, I need to distinguish between users who are using my clipboard through a unique id. Basically, I want to be able identify a person who is sat at one PC with one or more copies of visual studio (or similar) open. How do I do that? ps: This is at design-time. pps: It's not critical that it should work between copies of visual studio. One copy would be fine, or even one design surface.

• Does cache absolute expiration guarantee that the cache is eliminated at the exact time?

  - by Fabio Milheiro

  I am using the HttpRuntime cache to store lists of objects and in our current project it was specified that the objects should be cached until midnight, so I am using DateTime.Today.AddHours(24) in order to set the absolute expiration date to midnight. For example, if today is May 26th, the absolute expiration time will be set to May 27th 0:00. But somehow, when I change the clock of my computer, the objects are still in cache. Should I wait a little (the CacheItemPriority is set to Normal)? Am I forgetting something? Thank you

• Is calling of overload operator-> resolved at compile time?

  - by Brent

  when I tried to compile the code: (note: func and func2 is not typo) struct S { void func2() {} }; class O { public: inline S* operator->() const; private: S* ses; }; inline S* O::operator->() const { return ses; } int main() { O object; object->func(); return 0; } there is a compile error reported: D:\code>g++ operatorp.cpp -S -o operatorp.exe operatorp.cpp: In function `int main()': operatorp.cpp:27: error: 'struct S' has no member named 'func' it seems that invoke the overloaded function of "operator-" is done during compile time? I'd added "-S" option for compile only.

• ASP.net MVC How to run multiple instances of the same app at the same time in different subdomains?

  - by basilmir

  ASP.net MVC How to run multiple instances of the same app at the same time in different subdomains? I have a dozen or so subdomains. sub1.website.com sub2.website.com and the folder structure like this \website\sub1 \website\sub2 If i need to run the same app for all of the subdomains, what would be the best appoach? Host is in the root \website\ and have it figure out where to look based on the "user"? (i imagine i need to implement de logic in the code) OR Just copy the app in each of the subdomains, and have the app "not knowing" that it is actually an instance? (this would mean that when i update the app, i have to copy it everywhere) What other approaches are there to this kind of issue? Each app will use a different database name so that will need to we coded in somekind of external file.

  - by Geeta

  I have to search for a string in 10 large size files (in zip format 70 MB) and have to print the lines with the search string to corresponding 10 output files.(i.e. file 1 output should be in output_file1...file2--- output_file2). The same program takes 15 mins for a single file. But if use 10 threads to read 10 files and to write in 10 different files it should complete in 15 mins but its taking 40 mins. How can I solve this. Or multithreading will take this much time only?

• Is my program taking too much time to execute?

  - by Conrad C

  I wanted to solve a question from project euleur about finding the largest prime number of a big number. I run my code on a virtual machine on Visual studio 2012, and the code seems froze. When I step into the loop, the code works well, but when I execute it, the console is always there. It is as if the program is still running. Could it be that the program takes time to execute? My Code static void Main(string[] args) { long number = 5; for (long i = 1; i < 600851475143; i++) { if (i % 2 != 0 && i % 1 == 0 && i % i == 0) number = i; } }

• ASP.NET in VS IDE gives "Expression cannot be evaluated at this time."

  - by S Nash

  I read all of similar questions in SO but none seem to be an answer. Situation is simple. I have a ASP.NET webpage, In a VB code behind file I have the following line: iRendProvider = ddlProvider.SelectedItem.Value where iRendProvider is integer and ddlProvider is a dropdownlist. I put a breakpoint at the above line and code stops there. Now in the immdediate window in I type: ? ddlProvider.SelectedItem.Value I get "Expression cannot be evaluated at this time." If I step over iRendProvider = ddlProvider.SelectedItem.Value To the next line and I type ? iRendProvider , I see the correct value in the immediate window. Question is why this error and how to see contents of ddlProvider.

• What's the best way to write to more files than the kernel allows open at a time?

  - by Elpezmuerto

  I have a very large binary file and I need to create separate files based on the id within the input file. There are 146 output files and I am using cstdlib and fopen and fwrite. FOPEN_MAX is 20, so I can't keep all 146 output files open at the same time. I also want to minimize the number of times I open and close an output file. How can I write to the output files effectively? I also must use the cstdlib library due to legacy code.

• Component properties working at designt time but not runtime - ???

  - by delphi-rulez-2010

  I am creating a component that uses a collection and collection items of panels. I can't seem to get the colors to work at runtime, but yet they seem to work just fine at design time. You can download the component source code here: http://www.shaneholmes.net/pasfiles/ There is a Consoles (Tcollection) property, status colors property, and a Edit mode property Each console (TCollectionItem) has a status property when changed, the consoles property is changed based on the components StatusColors property. When the components EditMode property is set to true, you can move the panels around at runtime. Question: Why does the colors only work at designtime and not runtime. thanks

• Why exactly is calling the destructor for the second time undefined behavior in C++?

  - by sharptooth

  As mentioned in this answer simply calling the destructor for the second time is already undefined behavior 12.4/14(3.8). For example: class Class { public: ~Class() {} }; // somewhere in code: { Class* object = new Class(); object->~Class(); delete object; // UB because at this point the destructor call is attempted again } In this example the class is designed in such a way that the destructor could be called multiple times - no things like double-deletion can happen. The memory is still allocated at the point where delete is called - the first destructor call doesn't call the ::operator delete() to release memory. For example, in Visual C++ 9 the above code looks working. Even C++ definition of UB doesn't directly prohibit things qualified as UB from working. So for the code above to break some implementation and/or platform specifics are required. Why exactly would the above code break and under what conditions?

• Are there any ASP.NET MVC Real Time View Editors?

  - by BenMaddox

  I'm looking for a tool and I'm not even sure of the proper name. Please be patient with me as I explain. I'm doing a lot of html/mvc 2 work. Using the standard MVC 2 view engine, I would like to have an editor that shows real time changes in the browser. If I re-arrange div elements containing standard HTML and some server side components, I would like the browser to update without a manual refresh. Are there any tools that are currently available that would meet that requirement?

• I'm having a hard time wrapping my head around handling the Activity Lifecycle...

  - by kefs

  So it seems i've created a fatal flaw and coded an app before understanding/handling rotation/lifecycle events.. Currently, all of my code is in onCreate of each activity. I've read a lot of lifecycle tutorials online, including the official dev guide info, but i'm still having an almost unbelievably hard time trying to wrap my head around the rotation/lifecycle events/methods and when to use them correctly. For example, my app currently has an activity that opens the db, inserts a record, then closes the db.. if i rotate my screen on this activity, the data is re-entered into the db. Using the available lifecycle events (onPause(), onResume(), etc..), how would I prevent this db call from happening again? Would I have to pass a variable through the state saying that the db call has been done, and not to do it again? Thanks in advance..

• Should a company prevent employees from publishing an app in an appstore in their free time?

  - by Tommy

  My company is trying to pass a policy forbidding distribution of any application (even free) in any appstore for all developers. Their reasoning is that "outside work activities create a conflict of interest". They don't want that "you use your spare time to work on your app, and once it takes off you quit your job" (quoting the Head of Development). A few developers (myself included) have already said it was an abusive, pointless and most of all counter-productive policy (developers will actually be demotivated to work here under such control and to be denied of the freedom to distribute their project). Personally, I think it is actually in the interest of the company to promote side projects (even commercial activities, if there is no conflict). I'm also curious, is that common practice?

• Perl module for parsing natural language time duration specifications (similar to the "at" command)?

  - by Ryan Thompson

  I'm writing a perl script that takes a "duration" option, and I'd like to be able to specify this duration in a fairly flexible manner, as opposed to only taking a single unit (e.g. number of seconds). The UNIX at command implements this kind of behavior, by allowing specifications such as "now + 3 hours + 2 days". For my program, the "now" part is implied, so I just want to parse the stuff after the plus sign. (Note: the at command also parses exact date specifications, but I only want to parse durations.) Is there a perl module for parsing duration specifications like this? I don't need the exact syntax accepted by at, just any reasonable syntax for specifying time durations. Edit: Basically, I want something like DateTime::Format::Flexible for durations instead of dates.
