• autoexp.dat does not seem to take affect in Visual Studio C++ 2005 debugger.

  - by Pradyot

Just want commonly used stuff like stl::string, to display in a friendlier manner. Does anyone know. how I can accomplish this? Is this just question of specifying a path to the autoexp.dat file somewhere. The file is available under the Visual Studio installation directory.

• Qt C++ XML, validating against a DTD?

  - by Airjoe

  Is there a way to validate an XML file against a DTD with Qt's XML handling? I've tried googling around but can't seem to get a straight answer. If Qt doesn't include support for validating an XML file, what might be the process of implementing validation myself? Any good reference to start with in regards to validating XML against a spec? Thanks for the help!

• Check whether a folder is a local or a network resource in .NET

  - by rwmnau

  Is there a quick way to check whether a path I have is on a local disk or somewhere on the network? I can't just check to see if it's a drive letter vs. UNC, because that would incorrectly identify mapped drives as local. I assumed it would be a boolean in the DirectoryInfo object, but it appears that it's not. I've found classic VB code to do this check (through an API), but nothing for .NET so far.

• Why can't I create an array with size determined by a global variable?

  - by ashish yadav

  Why does the array a not get initialized by global variable size? #include<stdio.h> int size=5; int main() { int a[size]={1,2,3,4,5}; printf("%d",a[0]); return 0; } The compilation error is shown as "variable-sized object may not be initialized". According to me the array should get initialized by size.

• Is there a good .Net CSS aggregator that combines style sheets and minifies them?

  - by vfilby

I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

• Why does OAuth provide both an access token and an access token secret? Why not just a single value?

  - by jmbledsoe

  Why does OAuth include both an access token and an access token secret as two separate values? As a consumer or OAuth, all of the recommendations that I have seen indicate that I should store the token and secret together and essentially treat them as one value. So why does the specification require two values in the first place?

• How do you set the title attribute of an ASP.NET MVC Html.ActionLink to the generated URL

  - by Keith Hill

  I would like users to be able to see the corresponding URL for an anchor tag generated by Html.ActionLink() when they hover over the link. This is done by setting the title attribute but where I'm stuck is figuring out how to get that value: @Html.ActionLink(@testrun.Name, "Download", "Trx", new { path = @testrun.TrxPath }, new { title = ??) How can I specify the URL that ActionLink is going to generate? I could hardcode something I guess but that violates DRY.

• similar to __asm int 3 in Max OS X/ Xcode?

• What is the point of padding?

  - by ktm5124

  In particular, I'm reading into the Mach-O binary file format for Intel 32 on OS X. After the FAT header there is a whole bunch of padding before the offset of the first archive. What is the point of all this padding? To be more specific, there is upwards of 4000 bytes of padding between the FAT header and the first archive (in particular, the mach_header). Why include all these extra bytes?! Is OS X fond of adding 4 MB to all their universal binaries?

• How to add separator between items in a Spark List control

  - by simms2k

  I have a s:List where I've defined my own itemRenderer, and would like to insert a horizontal line separating items, similar to the way the mx:LinkBar works. I don't want to have a line at the top or bottom of the list, so I can't just include an upper or lower border in the itemRenderer. I was hoping the itemRenderer could be made aware of its index in the list, but I don't see how. Is there a way to do this?

• Eclipse: Should I create a workspace for each project ?

  - by Zombies

  I am simply wondering whether it is best to put all of my Eclipse projects into one workspace, or do a 1 workspace per 1 project. I am just a solo developer, for hobby more or less, but the apps I create do actually have production versions that are running on rather frequent cron jobs, so its almost like an amateur production environment. The only problems I have noticed so far is for exporting JARs, I have the potential to include source files from other projects which seems like it could get messy (maybe?).

  I recently read the source code of couch-db, I find this type definition which i don't understand: -type branch() :: {Key::term(), Value::term(), Tree::term()}. -type path() :: {Start::pos_integer(), branch()}. -type tree() :: [branch()]. I did read Erlang doc, But what is the meaning of Start, Key, Value and Tree? From what i understand, they are Erlang variables! I didn't find any information about this in Erlang doc.
