• Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

  - by SilverHorse

  I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.

• How does one create and use a pointer to an array of an unknown number of structures inside a class?

  - by user1658731

  Sorry for the confusing title... I've been playing around with C++, working on a project to parse a game's (Kerbal Space Program) save file so I can modify it and eventually send it over a network. I'm stuck with storing an unknown number of vessels and crew members, so I need to have an array of unknown size. Is this possible? I figured having a pointer to an array would be the way to go. I have: class SaveFileSystem { string version; string UT; int activeVessel; int numCrew; ??? Crews; // !! int numVessels; ??? Vessels; // !! } Where Crews and Vessels should be arrays of structures: struct Crew { string name; //Other stuff }; struct Vessel { string name; //Stuff }; I'm guessing I should have something like: this->Crews = new ???; this->Vessels = new ???; in my constructor to initialize the arrays, and attempt to access it with: this->Crews[0].name = "Ship Number One"; Does this make any sense??? I'd expect the "???"'s to involve a mess of asterisk's, like "*struct (*)Crews" but I have no real idea. I've got normal pointers down and such, but this is a tad over my head... I'd like to access the structures like in the last snippet, but if C++ doesn't like that I could do pointer arithmetic. I've looked into vectors, but I have an unhealthy obsession with efficiency, and it really pains me how you don't know what's going on behind it.

  - by Daren Thomas

  I am trying to assign an IronPython instance method to a C# Func<Foo> parameter. In C# I would have a method like: public class CSharpClass { public void DoSomething(Func<Foo> something) { var foo = something() } } And call it from IronPython like this: class IronPythonClass: def foobar(): return Foo() CSharpClass().DoSomething(foobar) But I'm getting the following error: TypeError: expected Func[Foo], got instancemethod

• How can I create an executable to run on a certain processor architecture (instead of certain OS)?

  - by CrazyJugglerDrummer

  So I take my C++ program in Visual studio, compile, and it'll spit out a nice little EXE file. But EXEs will only run on windows, and I hear a lot about how C/C++ compiles into assembly language, which is runs directly on a processor. The EXE runs with the help of windows, or I could have a program that makes an executable that runs on a mac. But aren't I compiling C++ code into assembly language, which is processor specific? My Insights: I'm guessing I'm probably not. I know there's an Intel C++ compiler, so would it make processor-specific assembly code? EXEs run on windows, so they advantage of tons of things already set up, from graphics packages to the massive .NET framework. A processor-specific executable would be literally starting from scratch, with just the instruction set of the processor. Would this executable be a file-type? We could be running windows and open it, but then would control switch to processor only? I assume this executable would be something like an operating system, in that it would have to be run before anything else was booted up, and have only the processor instruction set to "use".

• Cocoa & Cocoa Touch. How do I create an NSData object from a plain ole pointer?

  - by dugla

  I have malloc'd a whole mess of data in an NSOperation instance. I have a pointer: data = malloc(humungous_amounts_of_god_knows_what); uint8_t* data; How do I package this up as an NSData instance and return it to the main thread? I am assuming that after conversion to an NSData instance I can simply call: free(data); Yes? Also, back on the main thread how do I retrieve the pointer? Thanks, Doug

• How to create constant NSString by concatenating strings in Obj-C ?

  - by eric-morand

  Hi guys, I'm trying to instanciate a constant NSString by concatanating other NSString instances. Here is what I'm doing in my implementation file : static NSString *const MY_CONST = @"TEST"; static NSString *const MY_CONCATENATE_CONST = [NSString stringWithFormat:@"STRING %@", MY_CONST]; It leads to the following compilation error : Initializer element is not constant I suppose this is because stringWithFormat doesn't return a constant NSString, but since there is no other way to concatenate strings in Obj-C, what am I supposed to do ? Thanks for your help, Eric.

• How do I create a web service with rails?

  - by NotDan

  I have a silverlight application that needs to talk to a rails app to add a record. I have been able to get the silverlight app to successfully do the POST assuming everything goes good. Now, however, I need to be able to make it more robust and have the rails app return error/success messages to the silverlight app in a format it can read (xml maybe?). I can modify the rails app and silverlight app as needed. What is the best way to accomplish this with rails?

  - by rgksugan

  I am using java logging api to log errors in my exception. I am writing these errors to a log file. When i run my program i find a lot of files created.There are around 50 files created. Is there any mistake in my code or is it normal? Here goes the code try { logger = Logger.getLogger(Reciever.class.getName()); fileHandler = new FileHandler("Applicationlog.log", true); logger.addHandler(fileHandler); logger.setLevel(Level.ALL); SimpleFormatter formatter = new SimpleFormatter(); fileHandler.setFormatter(formatter); } catch (IOException ex) { logger.log(Level.SEVERE, null, ex); } catch (SecurityException ex) { logger.log(Level.SEVERE, null, ex); }

• Is it considered bad form to execute a function within a conditional statement?

  - by michael

  Consider a situation in which you need to call successive routines and stop as soon as one returns a value that could be evaluated as positive (true, object, 1, str(1)). It's very tempting to do this: if (fruit = getOrange()) elseif (fruit = getApple()) elseif (fruit = getMango()) else fruit = new Banana(); return fruit; I like it, but this isn't a very recurrent style in what can be considered professional production code. One is likely to rather see more elaborate code like: fruit = getOrange(); if(!fruit){ fruit = getApple(); if(!fruit){ fruit = getMango(); if(!fruit){ fruit = new Banana(); } } } return fruit; According to the dogma on basic structures, is the previous form acceptable? Would you recommend it?

• Can I create an ASP.NET MVC 2 project with multiple areas without referencing each Child in the pare

  - by No Refunds No Returns

  This is a follow-up question to my original query: http://stackoverflow.com/questions/1791605/how-can-i-use-multiple-projects-to-separate-a-large-asp-net-mvc-site-into-departm Now that I have this working, is there a way to still have multiple project but not have to reference each child area from the parent project? Ideally I'd like to be able to have multiple, separate and distinct projects that only come together on the production/test machines. I should be able to build and test each "area" separately.

• What is the best practise to create MSI with some other child MSI as prerequisite?

  - by sankar

  Currently we are using Innosetup as a bootstrapper to install the MSI prerequisites. It makes bit complex to maintain the setup. I found that burn tool which may help us to resolve this issue by having a single setup to install whatever we need. I could not find either documentation or sample for this tool. Is anyone have idea about this? or you can give me the alternate solution if you have. Looking for the alternate soltuion for the actions that we do with ISS bootstrapper now: Extract the files (Main setup, Prerequisite setup) Need to ensure prerequisites status and install on demand. Start main install.

• What build param(s) to use so VS 2010 can gen .obj & link .objs but NOT create an .exe?

  - by Csourcecode

  Question title pretty much asks it all. I know I could set the project to be a .lib build and have it fail to build/link a .lib .... and the .objs tend to be in the appropriate config dir That seems like a shi*-a** backdoor way to get VS to gen objs Is there a flag/param I can set somewhere in the property sheet properties/options for Visual Studio so it links what it needs to & gens the respective objs for each source file? It's so freaking easy to just gen object files using gcc (and link in appropriate lib routines WITHOUT creating an executable) ... I'm sure I could also hack up a custom build rule but that seems like overkill [and since I'm not up to speed on the build rules for whatever version of make VS 2010 is using it's easier to ask someone else here for the simple solution]

• How can I remove sensitive data from the debug_backtrace function?

  - by RenderIn

  I am using print_r(debug_backtrace(), true) to retrieve a string representation of the debug backtrace. This works fine, as print_r handles recursion. When I tried to recursively iterate through the debug_backtrace() return array before turning it into a string it ran into recursion and never ended. Is there some simple way I can remove certain sensitive key/value pairs from the backtrace array? Perhaps some way to turn the array to a string using print_r, then back to an array with the recursive locations changed to the string RECURSION, which I could the iterate through. I don't want to execute regular expressions on the string representation if possible.

• Do you think it's a good idea to create a login box as a user control?

  - by Sergio Tapia

  Hi there guys! I'm starting out learning some ASP.Net programming and I'm going to be making a little community website for my friends and myself. I'm trying to pick up some good habits along the way. I was thinking of having a usercontrol and have that 'loginBox' shows the appropriate textboxes and login button, but also show his username when he is logged in. Do you think I should handle this as a user control or am I missing something as an ASP.Net newbie?

• What to use to create bar, line and pie charts with javascript compatible with all major browsers?

  - by marcgg

  I used to work with flot but it doesn't support pie charts so I'm forced to change. I just saw JS Charts, but their documentation is very obscure regarding cross browser compatibility (I need it to be IE6+ compliant :). Also this will be for commercial use, so I'd rather have something that I can use free of charge jQuery Google chart looks really nice and is well integrated with rails (the framework I'm using) but I'm not sure how good it is. So what do you guys use? What would you recommend keeping in mind that: It will be for commercial use (I can deal with a license, but I'd rather avoid that) It needs to be javascript (no svg, no flash please) It needs to be compatible with IE6+, FF, Chrome, Opera and Safari It needs to be pretty ^^ If it uses jQuery it's even better
