• large images on toolbar

  - by cagi

  Hi to all. Is it possible to have a 32x32 images on toolbar while keeping 16x16 in menu. I created toolbar resource (IDR_TOOLBAR1) and set it's button size as 32x32 and load it: if (!m_wndToolBar.CreateEx(this,...) || !m_wndToolBar.LoadToolBar(IDR_TOOLBAR1 )) { ... } When started toolbar correctly shows large btn images but menu is also enlarged showing 32x32 item images!? How to have menu images as before (small 16x16) My app info: SDI, VS2008 Thanks in advance! P.S. I have noticed an option check box "Large Images" in quick customization dialog under options tab. The dialog is enabled by default in my project. When selecting that option images buttons enlarge instantly, the problem is the new sized images is created from small ones and quality is poor. It would be better if new images list is loaded? Once again thanks in advance!

• ASP.NET MVC - Add XHTML into validation error messages

  - by Neil

  Hi, Just starting with ASP.Net MVC and have hit a bit of a snag regarding validation messages. I've a custom validation attribute assigned to my class validate several properties on my model. When this validation fails, we'd like the error message to contain XHTML mark-up, including a link to help page, (this was done in the original WebForms project as a ASP:Panel). At the moment the XHTML tags such as "< a ", in the ErrorMessage are being rendered to the screen. Is there any way to get the ValidationSummary to render the XHTML markup correctly? Or is there a better way to handle this kind of validation? Thanks

• WPF. How do I create many LIstViews with the same look.

  - by Erik Z

  I've defined a listview in my recent project and realized that I will be using more listviews looking exactly the same and having the same solumns. Since I'm new to WPF am I curious of teh best way to do this. Is it to create a usercontrol? Use styles? I've tried to use styles but it didnt work the way I was hoping. I tried to set the "View" property using style, like this. <Style x:Key="ListViewStyle" TargetType="{x:Type ListView}"> <Setter Property="View"> <ListView.View> <GridView> But it didnt work so I'm asking for your opinion?! Thanks.

• implmenting 1 to n mapping for ORM c++

  - by karan

  I am writing a project where i need to implment a stripped down version of an ORM solution in c++. I am struck in implmenting 1-n relationships for the same. For instance, if following are the classes: class A { } class B { std::list _a_list; } I have provided load/save menthods for loading/saving to the db. Now, if i take the case of B : Say , for the following workflow : 1 entry from _a_list is removed 1 entry from _a_list is modified 1 entry is added to _a_list Now, i need to update the db using something like "b.save()". So, what would be the best way to save the changes,i.e, identify the additions, deletions and updations to _a_list.

• Restart Delphi Application Programmatically

  - by Smasher

  It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

• wanting to move up from ms access, thinking .net? visual studio?

  - by Tristan Lear

  So I wrote a project-management program for a small business using Microsoft Access 2007. Now they've requested lots of additional features (timekeeping, privileged data tiers ...) I personally use Linux, but the whole office uses Windows. I'm relatively new to programming but like to teach myself using projects like this. I'm right on the edge on this -- I can't really tell what the path of least resistance here is: do I stay in access + VBA and teach myself a dying, annoying language -- while struggling against all the limitations of Access? Or do I move to something else? Python seems simple enough ... Whatever I use, i need to be able to offer a GUI.

• What is a good way to sync code files between computer?

  - by erotsppa

  I have a need to code from two computers during the week. What is the best way to sync the two computers (mac)? I've started using source control, like SVN. It works pretty good, except sometimes I check in code that I want to sync but they don't compile and it interferes with other people on the team working on the same project. I don't want to use branch. It wouldn't make sense to branch every night when I head home from office.

• java.lang.UnsupportedClassVersionError in eclipse

  - by Derek

  Hi all, I am not a Java programmer really, so I am posting this question. The exception is being thrown java.lang.UnsupportedClassVersionError in my main class in an eclipse project. If I comment out the imports that this class has, it compiles and runs fine. If I put the imports back in, it does not work. Does this mean that the libraries I am importing were compiled with a newer or older version of java than I have? when i do java -version on the system i get 1.5_07 I could've sworn this was actually working last week, but maybe some setting in eclipse got tweaked? Is the Java Build Path in eclipse what I need to look for to check the JRE and compiler versions?

• Problem with VisualBasic

  - by Michael

  Ok, I am sure this is simple but I am not able to figure it out and people on this site seem to be brains... I will admit this is for homework but it has nothing to do with how to code. Has to do with a silly error that I am unable to resolve. I try to debug and when I debug i get the following error ERROR "Visual Studio cannot start debugging because debut target 'C:\Documents and Settings\user\Desktop\programs6\HuricaneSeasonStatistics\bin\Debug\HuricaneStatistics.exe" is missing. Please build the project and retry, or set the OutputPath and AssemblyName properties appropriate to point a the correct location for the target assembly." I am fairly sure the error is in the OutputPath and or AssemblyName. but I am not sure where to change.

• How to debug a WCF Service with an HTTP Context?

  - by JL

  I need to debug a WCF service but it needs to have an HTTP Context. Currently I have a solution with a WCF service web site, when I click on debug it starts up and then fires up an html page that contains no test form. While the project is running I tried starting the wcftestclient manually, then provided the address of my service, it finds the service but when I invoke it, it bypasses the IIS layer (or development server), so the httpContext is null... What is the correct way to debug a WCF service through an IIS context?

• Multi-process builds in Visual Studio 2010: Worth it?

  - by coryr

  I've started testing our C++ software with VS2010 and the build times are really bad (30-45 minutes, about double the VS2005 times). I've been reading about the /MP switch for multi-process compilation. Unfortunately, it is incompatible with some features that we use quite a bit like #import, incremental compilation, and precompiled headers. Have you had a similar project where you tried the /MP switch after turning off things like precompiled headers? Did you get faster builds? My machine is running 64-bit Windows 7 on a 4 core machine with 4 GB of RAM and a fast SSD storage. Virus scanner disabled and a pretty minimal software environment.

• Looking for C# framework for plotting scientific data: 2d/3d ...

  - by Ivan

  I need to visualize some scientific calculations. I generally prefer reusing code if there is already a good available instead of inventing wheels each time, that's why I am asking. I need a C# code to draw charts (just outputting a bitmap is ok) of 2d (y=f(x)) and 3d (z=f(x,y)) digital data sets (where any axis can be float, int or datetime), sometimes combined. If I go here and click 3D in the navigation bar on the left, there I can see what I need. But the cheapest version costs $759 there, looks scary for a hobby project of an east-european student :-(

• Why do external Java libraries paths have to be refreshed in eclipse between starts?

  - by Jason

  For my school projects, I use the joda-time API for generating timestamps that are used for file names and logging. Getting eclipse to recognize the library is no problem. However, when I start eclipse between reboots, I get the red X in the project tree because the external API cannot be found, even though the file path has not changed. So each time, I have to go to the Libraries tab in Build Path to re-target the API. Frankly, this is getting to be a PIMA. So is there any way to have the path be permanent, so I don't have to do the Build Path rigmarole all the time?

• dynamic silverlight content

  - by Jeremy

  I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

• The C++ 'new' keyword and C

  - by Florian

  In a C header file of a library I'm using one of the variables is named 'new'. Unfortunately, I'm using this library in a C++ project and the occurence of 'new' as a variable names freaks out the compiler. I'm already using extern "C" { #include<... }, but that doesn't seem to help in this respect. Do I have to aks the library developer to change the name of that variable even though from his perspective, as a C developer, the code is absolutely fine, as 'new' is not a C keyword?

• Actionscript classes to 1 SWC file

  - by Daryl

  I'm using Flash Builder 4 (the version after Flex Builder 3, so very similar to Flex Builder 3) and have a bunch of actionscript classes that I frequently need to reference. I have them in a separate folder/package to keep things clean. I know that it's possible to create a SWC from these actionscript files. My question is how do I do it in Flash Builder 4 or Flex Builder 3. Do I need other tools? My objective is just to use the SWC in the project and keep things clean instead of dragging around all these files.

• When and why are you planning to upgrade to Python 3.0?

  - by Tomislav Mutak

  Python 3.0 (aka Python 3000, Py3k, etc) is now available. When and why are you planning on porting your project or code to the new Python? edit: I'm particularly interested in any features that don't exist in 2.6 that make porting worth it. Right now seems like a lot of negatives (x hasn't been ported yet), but I don't know what people see as the positives. Regarding "when", I'm interested in people's thoughts that the first step to porting is to have "excellent test coverage" which seems a bit optimistic for some projects.

• Exposing APIs - third party or homegrown?

  - by amelvin

  Parts of the project I'm currently working on (I can't give details) will be exposed as an API at some point over the next few months and I was wondering whether anyone could recommend a third party API 'provider' (possibly Mashery or SO advertiser Webservius). And I mean recommend in the 'I've used these people and they are good' sense because although I can google for an answer to this question it is more difficult to get truly unbiased opinions. As an addendum is there much mileage in creating a bespoke API solution and has anyone had any joy going down that road? Thanks in anticipation.
