  • What's a good, threadsafe, way to pass error strings back from a C shared library

    - by PerilousApricot
    Hello, all- I'm writing a C shared library for internal use (I'll be dlopen()'ing it to a c++ application, if that matters). The shared library loads (amongst other things) some java code through a JNI module, which means all manners of nightmare error modes can come out of the JVM that I need to handle intelligently in the application. Additionally, this library needs to be re-entrant. Is there in idiom for passing error strings back in this case, or am I stuck mapping errors to integers and using printfs to debug things? Thanks!

  • How to link to a folder in document library from sharepoint list item?

    - by kyrisu
    Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?

  • jquery not working in mvc after publishing to server

    - by czuroski
    Hello, I've built an mvc application which contains some jquery code. When I run the app from my ide, everything works perfectly. When I publish to the server and open the page, the jquery does not work. I get object expected errors. Could this be due to my file mappings? here is a sample of my mapping in the app - <script type="text/javascript" href="../../Scripts/jquery-1.3.2.js"></script> I published the app to iis7 successfully, but the jquery is broken. I did publish to an application within an existing web site. Any thoughts?

  • Django ModelAdmin.save_model() -vs- ModelAdmin.save_formset()

    - by anonymous coward
    I want to ensure that a user editing a particular model is saved in that models updated_by (FK User) field. I'm using mostly ModelForms (not necessarily the built in Admin), and wondering: In what cases would I need to override ModelAdmin.save_model() or ModelAdmin.save_formset()? Or, is that doing it wrong? If it's just the models' save() method that needs to be overridden, is there a proper way to access the request object there?

  • Do I need to create icons other than RGBA for my Windows app?

    - by user843732
    I'm curious if anyone still creates icons other than RGB/A (or 32-bit with alpha-channel) for your Windows apps? PS. I know that suggested model is to create 256-color versions of icons, but I always struggle with those. If I automatically convert them in an icon editor they totally decimate the look of my original icons with jagged edges and circa-Windows95 look. So if those are still required, does anyone know the stats on how many people are still using color settings other then 32-bit TrueColor?

  • Using jQuery, how do I way attach a string array as a http parameter to a http request?

    - by predhme
    I have a spring controller with a request mapping as follows @RequestMapping("/downloadSelected") public void downloadSelected(@RequestParam String[] ids) { // retrieve the file and write it to the http response outputstream } I have an html table of objects which for every row has a checkbox with the id of the object as the value. When they submit, I have a jQuery callback to serialize all ids. I want to stick those ids into an http request parameter called, "ids" so that I can grab them easily. I figured I could do the following var ids = $("#downloadall").serializeArray(); Then I would need to take each of the ids and add them to a request param called ids. But is there a "standard" way to do this? Like using jQuery?
