  • IAR Embedded Workbench MSP430 and *.lib files linking

    - by jeniusj
    I was assuming that it was a really simple task but I did not find anything relevant or my mistake. So putting my problem here i.e. I have some project for MSP430 which is actually in code composer studio. I have to run this whole code into IAR embedded workbench now. There are some library files(*.lib) that are also provided with the project and that should have to be linked to build the project. After little modifications code is compiling fine but I am unable to link the libraries and getting linker errors. I worked on IAR with avr but very very little just to test some sample codes. I did not find the option where to mention these library names and their respective paths. I checked out the linker tab but I am not getting any clue to link these .lib files with project.

  • Following PHP coding of Wisdom

    - by justjoe
    i read some wisdom like this : Programmers are encouraged to be careful when using by-reference variables since they can negatively affect the readability and maintainability of the code. i make my own solution, such as give suffix such as _ref in every by-reference variables. so, if i have a variable named as $files_in_root, then i will add suffix and changes it name into $files_in_root_ref. As far my knowledge goes, this is a good solution. So, here come the question Is there any best-practice on choosing suffix for by-reference variable in PHP coder world ? Or do you have any ? In general, how do we sustain readability and maintainability on PHP project with more then 3000 line of code ? I hope PHP coder world has unwritten aggrement for first question, cause it will help spot a pattern on any source code.

  • Looking for Eclipse plugin: Lock source tabs in place

    - by Fredrik
    When working with java code in Eclipse I can typically juggle between 20-40 different files, but there usually are just two that I actively work with at the time (test and code). Going back to the code where I want to work after having debugged through 5-10 classes can be a pain. So what I would like to do is to be able to right click on the tab of a class and choose to lock them in place. The classes would then always be available as the first and second tabs furthest to the left in the editor. All other classes (and other files opened in the editor) would then fight over the remaining space in the editor like today. Is there a plugin like this? My google-fu might not be strong enough, cause I find nothing.

  • iPhone: Having trouble figuring out how to scroll a UITableView with custom UITextField cells automa

    - by Gordon Fontenot
    Ok, I know this seems like a duplicate question, but don't think it is. I actually have this implemented already (thanks to this SO question), but it seems sluggish. I am willing to tweak it a bit, but I ran across a demo app by AboutObjects that seems to have exactly the right functionality with absolutely no code doing it. I have looked through their demo code dozens of times, and I can't figure out what they are doing that I am not. The code to look at is in their iPhone Development Tutorials section, and is called "Editable TableView" (2nd from the bottom). There are a couple of questions on the forums on that site asking how they got the functionality, but there is no answer (other than "It's a built in function"). Does anyone have any clue as to why their UITableView would implement the input scrolling by default (including being able to scroll the view manually when the keyboard pops up, which I cannot get to work)?

  • Question about spring manning-in-action

    - by Gandalf StormCrow
    I saw people asking about best book for learning spring, and I came across manning.spring in action was recommended most of the time so I decided to give it a go. The thing is the author offers some pretty reasonable explanations, puzzle by puzzle it gets in your head, than you just need to code it and you're done, you get it(this is how I work don't know about the others). When it comes to the code its very disapointing, I went trought the Knight example like 2 or 3 times by now and I see its incorrect in the book, I mean its hard already for people eager to learn and why not a note somewhere in the book like pseudo-code or something. The knight example in the first chapter is missing two classes QuestFailedException and HolyGrail I mean other people must have noticed this, why is everyone recommending this book without saying at least it has some errors(like many others do), was anyone actually been able to compile and this first chapter example?

  • .net dictionary and lookup add / update

    - by freddy smith
    I am sick of doing blocks of code like this for various bits of code I have: if (dict.ContainsKey[key]) { dict[key] = value; } else { dict.Add(key,value); } and for lookups (i.e. key - list of value) if (lookup.ContainsKey[key]) { lookup[key].Add(value); } else { lookup.Add(new List<valuetype>); lookup[key].Add(value); } Is there another collections lib or extension method I should use to do this in one line of code no matter what the key and value types are? e.g. dict.AddOrUpdate(key,value) lookup.AddOrUpdate(key,value)

  • Plot hex tiles with different length sides?

    - by Phil
    I'm trying to create a basic grid of hex tiles. I found some code... s=h/Math.cos(30*Math.PI/180)/2; tile._x=x*s*1.5; tile._y=y*h+(x%2)*h/2; That does just that, but I think it's setup for hex's that have same length sides. However my hex has different length sides. It's width is 140 and it's height is 80. I could completely change the code to work with my side lengths, but I was wondering if there's a better way of doing it with the code above.

  • How to center text around point using xaml

    - by Pete d'Oronzio
    I would like to be able to place the word "hello" centered on a specific point. I need to do this completely in XAML without extra code. Best I can tell, all the text alignment properties/styles in XAML act on text within some bouding canvas or other element. Since I don't know the length of the text I want to center, I can't center it using my own code. The reason I need to solve the problem entirely in XAML is that I'm not using WPF to create the XAML, I'm writing it directly to an XML DOM. It will then be loaded into a Silverlight or WPF control for display. In most graphic languages, including SVG, which is where my code originated, text can be aligned against a "stationary point" without a bounding box. Any suggestions appreciated

  • CommandManager Executed Events don't fire for custom ICommands

    - by Andre Luus
    The WPF CommandManager allows you to do the following (pseudo-ish-code): <Button Name="SomeButton" Command="{Binding Path=ViewModelCommand}"/> And in the code-behind: private void InitCommandEvents() { CommandManager.AddExecutedEventHandler(this.SomeButton, SomeEventHandler); } The SomeEventHandler never gets called. To me this didn't seem like something very wrong to try and do, but if you consider what happens inside CommandManager.AddExecutedEventHandler, it makes sense why it doesn't. Add to that the fact that the documentation clearly states that the CommandManager only works with RoutedCommands. Nonetheless, this had me very frustrated for a while and led me to this question: What would you suggest is the best workaround for the fact that the CommandManager does not support custom ICommands? Especially if you want to add behavior around the execution of a command? For now, I fire the command manually in code behind from the button click event.

  • Windows Constants for Ctrl+X, Ctrl+C, and Ctrl+V

    - by Jonathan Wood
    I've got some older MFC code I wrote that I'm "freshening up" a bit. I have the following code in a window class' OnChar() handler. I really don't like using constants like 0x18. I'd like to make the code more readable. I know I can declare my own, but are there no Windows macros for these values? I couldn't find anything about this on the web. // Check for clipboard commands switch (nChar) { case 0x18: // Ctrl+X - Cut OnEditCut(); break; case 0x03: // Ctrl+C - Copy OnEditCopy(); break; case 0x16: // Ctrl+V - Paste OnEditPaste(); break; }

  • Difference in DLL when compiling on Build Server instead of Dev Machine.

    - by Achilles
    I have an application that loads user controls into .NET web application. When I compile and test the application locally on my dev machine it works on my machine. The project builds successfully using MSBuild on our build server. However when I deploy the dll generated by MSBuild on the build server I get the following error when the application loads the control: BC30456: 'CreateResourceBasedLiteralControl' is not a member of 'ASP.usercontrols_somecontrol_ascx'. I took a look and compared the dll generated on my machine and compared it(looked at the file size) with the one created by the build server and noticed a difference in the file size. This is confusing considering the code being built locally and on the build server is IDENTICAL. I manually compared each file by hand. So my question is: What is causing this error? What would be different between MSBuild's compilation of the code and what is going on in Visual Studio when compiling the code?

  • Finding parents where child collection does not contain an item with a specific property value

    - by Colin Bowern
    I am trying to get a list of parents where the child collection does not contain an item of a specific type. The LINQ equivalent would be something like: dataset.Where(x => x.Items.FirstOrDefault(y => y.Type.Code == "ABC") == null) The object model is Parent Child (Items) Type Code If Parent is my aggregate root, how would I model this in NHibernate criteria/query? Here's my first attempt: var results = session.CreateCriteria<Parent>() .CreateCriteria("Items") .CreateCriteria("Type") .Add(Restrictions.Not(Restrictions.Eq("Code", "ABC"))) .SetResultTransformer(Transformers.DistinctRootEntity) .List<Parent>(); This doesn't seem to return the right entities - it just returns them all.

  • Java + MS Exchange: how to retrieve .msg files

    - by Cesar
    Dear people, I've created a Java program with which I can retrieve mail from an Exchange mailserver. Problem is: the mail is in EML format and I need the MSG format! Right now I'm retrieving mail through the web access part of Exchange, using the Apache Slide project... is it possible at all to use java to retrieve msg files from an Exchange server? I've seen examples of C# code, .NET code etc.. isn't it possible somehow to integrate these pieces of code with Java so I can use it to retrieve mail? Greets, Cesar

  • How to add animation on open of a Jquery SimpleModal?

    - by Obay
    The animation-enabled example in the SimpleModal site has this animation: 1. Fade in the overlay 2. Slide down the modal div This is the code: $("#the-div").modal({ onOpen: function (dialog) { dialog.overlay.fadeIn('fast', function () { dialog.data.hide(); dialog.container.show('fast', function () { dialog.data.slideDown('fast'); }); }); }}); I want this animation instead: 1. Just display the modal 2. Fade in the overlay Alas, simply removing the 2nd parameter of dialog.overlay.fadeIn() from the code above doesn't work. I also tried removing the parameters of dialog.container.show(), also changing it to dialog.container.open(). I've tried other combinations of the code, to no avail. How do I achieve the animation that I wish?

  • Can I debug with python debugger when using py.test somehow?

    - by Joel
    I am using py.test for unit testing my python program. I wish to debug my test code with the python debugger the normal way (by which i mean pdb.set_trace() in the code) but I can't make it work. Putting pdb.set_trace() in the code doesn't work (raises IOError: reading from stdin while output is captured). I have also tried running py.test with the option --pdb but that doesn't seem to do the trick if I want to explore what happens before my assertion. It breaks when an assertion fails, and moving on from that line means terminating the program. Does anyone know a way to get debugging, or is debugging and py.test just not meant to be together?

  • VC7.1 C1204 internal compiler error

    - by Nathan Ernst
    I'm working on modifying Firaxis' Civilization 4 core game DLL. The host application is built using VC7, hence the constraint (source not provided for the host EXE). I've been working on rewriting a large chunk of the code (focusing on low-hanging performance issues & memory leaks). I recently ran into an internal compiler error when trying to mod the code to use an array class instead of dynamically allocated 2-d arrays, I was going to use matrices from the boost lib (Civ4 is already using boost, so why not?). Basically, the issue comes down to: if I include "boost/numeric/ublas/matrix.hpp", I run into an internal compiler error C1204. MSDN has this to say: MSDN C1204 KB has this to say: KB 883655 So, I'm curious, is it possible to solve this error without a KB/SP being applied and dramatically reducing the complexity of the code? Additionally, as VC7 is no longer "supported", does anyone have a valid (supported) link for a VC7 service pack?

  • MSDN "pseudoframe"

    - by bobobobo
    So, I'm trying to replicate MSDN "pseudoframes" here.

  • VS C++ throwing divide by zero exception after a specific check

    - by Dr. Monkey
    In the following C++ code, it should be impossible for ain integer division by zero to occur: // gradedUnits and totalGrades are both of type int if (gradedUnits == 0) { return 0; } else { return totalGrades/gradedUnits; //call stack points to this line } however Visual Studio is popping up this error: Unhandled exception at 0x001712c0 in DSA_asgn1.exe: 0xC0000094: Integer division by zero. And the stack trace points to the line indicated in the code. It seems like VS might just do this with any integer division, without checking whether a divide by zero is possible. Do I need to catch this exception even though the code should never be able to throw it? If so, what's the best way to go about this? This is for an assignment that specifies VS 2005/2008 with C++. I would prefer not to make things more complicated than I need to, but at the same time I like to do things properly where possible.

  • PerformSelectorInBackground leaking on device

    - by Oysio
    While it seems to not pose a problem on the simulator, using performSelectorInBackground on the device causes memory leaks. Or at least that's what Instruments indicates. Looking at the code I don't have a single clue what the cause could be. I tried to strip the affected code to a bare minimum but still strangely Instruments keeps showing a leak every time this piece of code is executed. Anything unusual going on here? //In viewcontrollerA: -(void)mainLoop { [self.viewControllerB performSelectorInBackground:@selector(calculateTotals) withObject:nil]; //This gives the same problem //[NSThread detachNewThreadSelector:@selector(calculateTotals) toTarget:self.viewControllerB withObject:nil]; //UI stuff ... } //viewControllerB: -(void)calculateTotals { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; //Heavy calculations ... [pool release]; }

  • Excel found unreadable content in ...

    - by Rashmi Pandit
    Hi, When I open an excel file (generated through VBA code), I get an error "Excel found unreadable content in <filename>. Do you want to recover the contents?" Upon clicking yes, I get a message 'Repairs were made to PivotTable report 'pvtName' on '[filename.xls]Tab'.' The pivot table in question is generated by the VBA code. Is there a way to figure out what repairs are being done on the pivot table, so that I can make the necessary changes in the code before the file is generated? Thanks :)

  • python: iif or (x ? a : b)

    - by Albert
    If Python would support the (x ? a : b) syntax from C/C++, I would write: print paid ? ("paid: " + str(paid) + " €") : "not paid" I really don't want to have an if-check and two independent prints here (because that is only an example above, in my code, it looks much more complicated and would really be stupid to have almost the same code twice). However, Python does not support this operator or any similar operator (afaik). What is the easiest/cleanest/most common way to do this? I have searched a bit and seen someone defining an iif(cond,iftrue,iffalse) function, inspired from Visual Basic. I wondered if I really have to add that code and if/why there is no such basic function in the standard library.

  • Continuous builds and Agile vs commit often

    - by Mark Underwood
    Hi All, I'm just doing some formal training in Agile at the moment and one question I have is about the value of Continuous Builds vs value of committing to the version control system often. My understanding with version control is that its better to commit often, because then you have history and the ability to go back to previous changes in a fine grained way. My understanding with Agile and continuous build is that its there to put pressure on the developers to always have working code. That to break the source tree is a taboo thing to do. Now i agree with both of these sentiments, but it occurs to be that sometimes these might be working against each other. You maybe in the middle of a largish code change and want to commit code to make sure you have history, but this will break the source tree. Anybody got any thoughts on this? Cheers Mark.
