• How do I use the Windows API Code Pack in VB.net 2010 Express?

  - by Josh

  Hi all, I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources. Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?

• Is it beneficial to development to use a case-sensitive file system?

• Pull dynamic string out of embedded RESX

  - by AC

  I have a RESX resource file that I can retrieve the values out of using the strongly typed properties and assign to values in my Silverlight 3 app. However at runtime I need to generate the lookup key based on some values to avoid a ton of if/switch statements. I'm trying to use the ResourceManager, but it doesn't like .resx files. Searched far and wide... is this just not possible in SL3? Does anyone have another suggestion?

• Save simple data in Magento's DB w/o Model

  - by Joseph Mastey

  I'm looking to save some data in the Magento database without hassling with creating a new EAV object (or even a DB table if I can avoid it). Is there any place that you all know about that Magento will let you store serialized data? If it matters, the data is a serialized set of SKUs that I need to retrieve. I know that I could create a new model, or possibly even create an attribute as a flag on each product, but those are both really overkill for my purposes. Thanks, Joe

• Eclipse RCP setting classpath from workspace

  - by English Learner

  I am working one Eclipse RCP project where I have got one situation that I wanted to set classpath at runtime. So initially, I can set the classpath from project\lib\sample.jar file in order to avoid the compilation error. But once the Eclipse RCP application started, and click one update button, a new sample.jar file would be generated at workspace. Now I wanted to update the classpath for newly generated sample.jar from workspace. Which is the best option for setting such a runtime classpath ?

• How can my WiX uninstall restore a registry value change?

  - by Thomas

  The installer I'm writing using WiX 3.0 uses a RegistryValue element to modify an existing registry value (originally written by our main product). I'm trying to figure out a way to restore the registry value when the user uninstalls my utility. I'd like to avoid using a custom action, but that might be the only recourse? TIA.

• How do I make an HTML text box show a hint when empty?

  - by Michael L Perry

  I want the search box on my web page to display the word "Search" in gray italics. When the box receives focus, it should look just like an empty text box. If there is already text in it, it should display the text normally (black, non-italics). This will help me avoid clutter by removing the label. BTW, this is an on-page AJAX search, so it has no button.

• Running Python scripts in a browser

  - by sunwukung

  I want to start learning Python - and I'm having trouble getting scripts to load up in a browser (using Wamp). So far I've tried the following: 1: add the following lines to httpd.conf: AddHandler cgi-script .py Options ExecCGI I navigate to localhost/path/to/script/myscript.py but get an Internal Server error. 2: downloaded mod_wsgi-win32-ap22py26-3.0.so - renamed to mod_wsgi (running Wamp with Apache 2.2) added the following lines to httpd.conf AddHandler mod_wsgi .py WSGIScriptAlias /wsgi/ "path/to/my/pythonscripts/folder/" but when I navigate to the script - it renders the script in it's entirety i.e. #!c:/Python26/python.exe -u print "hello world" I managed to get CherryPy working, but ideally I want to learn the language in a relatively raw context before digging into a framework. Can anyone give me some pointers?

• Ubuntu 10.4 Lucid Server Minimal Install: Slow terminal scrolling

  - by noname

  I have a minimal install of Ubuntu 10.4 Server for testing and learning purposes. There is a very annoying occurrance: whenever I try to "man dpkg" or any command that load a few screens length of text (eg. "ls -al") the redraw speed of the console is just way too slow. I can see how each new line causes the whole screen to redraw. Note: that this doesn't happen inside X. No gui is installed. I have been experimenting with adding vesafb to the grub line as some guides suggested, but no speedups happened. You might be able to reproduce this behaviour on your linux system by switching to terminal using CTRL+ALT+F1. Is there any way to speed scrolling up?

• Regex: How do I match some regex logic 1 or more times?

  - by tom

  I already have some regex logic which says to look for a div tag with class=something. However, this might occur more than once (one after another). You can't simply add square brackets around that complex regex logic already (e.g. [:some complicated regex logic already existing:]* -- so how do you do it in regex? I want to avoid having to use the programming language logic to append that regex logic after itself if I can... Thanks

• Is there a boolean literal in SQLite?

  - by Benjamin Oakes

  I know about the boolean column type, but is there a boolean literal in SQLite? In other languages, this might be true or false. Obviously, I can use 0 and 1, but I tend to avoid so-called "magic numbers" where possible. From this list, it seems like it might exist in other SQL implementations, but not SQLite. (I'm using SQLite 3.6.10, for what it's worth.)

• why is java.lang.Throwable a class?

  - by mdma

  In java adjectives ending in -able are interfaces Serializable, Comparable etc... So why is Throwable a class? Wouldn't exception handling be easier if Throwable were an interface? Obviously, changing it now is out the question. But could it be made abstract? Wouldn't that avoid the bad practice of throw new Throwable();

• Is there a convention, when using Java RMI, to use the dollar sign $ in a variable name?

  - by Thomas Owens

  I realize that it is a valid part of a variable name, but I've never seen variable names actually use the symbol $ before. The Java tutorial says this: Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. However, since this is geared toward Java beginners, I'm wondering if in the distributed world, the $ lives on with a special meaning.

• How to bundle a native library and a JNI library inside a JAR?

  - by Alex B

  The library in question is Tokyo Cabinet. I want is to have the native library, JNI library, and all Java API classes in one JAR file to avoid redistribution headaches. There seems to be an attempt at this at GitHub, but It does not include the actual native library, only JNI library. It doesn't work (for me): when I use this JAR, the JVM does not even seem to find the JNI library which is packaged inside the JAR: java.lang.UnsatisfiedLinkError: no jtokyocabinet in java.library.path (tokyo_cabinet.clj:19)

• Pass data to a HttpModule

  - by Dejan

  I have a funny little situation on my hands. I have a httpModule on my hands that I have to feed with context relative data. That means that on the page I have to set something that the HttpModule can then react on. If possible I would like to avoid having call context data in the session. Any bright ideas out there. thx for the answer.
