• how to return NULL for double function with Intel C compiler?

  - by Derek

  I have some code that I am porting from an SGI system using the MIPS compiler. It has functions that are declared to have double return type. If the function can't find the right double, those functions return "NULL" The intel C compiler does not like this, but I was trying to see if there is a compiler option to enable this "feature" so that I can compile without changing code. I checked the man page, and can't seem to find it. Thanks

• settings file vs app.config

  - by fearofawhackplanet

  I'm not really understanding the interaction/differences between settings and config files. If I add an entry to the settings file, it gets added to the app.config as well. Does this mean that changing the value in the app.config will update the settings? If not, how do I update settings in a live application? What's the general purpose of using a settings file instead of putting things directly in app.config?

• Windows7 run as admin with password

  - by dakull

  I love running as a standard user for its security pluses, my admin account is password protected. The problem appears when I need to run a program that requires admin rights, is there a way to include the password somehow so I won't have to type it every time ? Without changing my current setup: admin password protected account and I log on to a limited standard user account. I'm thinking of script or something like that ?

• Is the xul button element in a firefox sidebar editable with CSS?

  - by user290384

  I have been trying to change the style of buttons in my firefox extension sidebar with a CSS file (change skin). However, the buttons don't seem to take over the style changes. I tried both background images and just changing color etc., which are both not working. Is it possible to influence the button style at all in my firefox extension sidebar?

• [zsh] how to clone a local git repository whose name contains a `:'?

  I'm trying to clone a local git repository. The repository's name contains a `:'. This is confusing both me and git. I get the following error: ~/work/c% git clone ../a::b . Initialized empty Git repository in /home/user/work/c/.git/ ssh: Could not resolve hostname ../a: Name or service not known fatal: The remote end hung up unexpectedly How would you escape the `:'? For now I'm just changing the name of the original repository :-) I'm using zshell...

• C# or windows equivalent of OS X's Core Data?

  - by Nektarios

  I'm late to the boat and have only just now started using Core Data in OS X / Cocoa - it's incredible and is really changing the way I look at things. Is there an equivalent technology in C# or the modern Windows frameworks? i.e. having managed data types where you get saving, data management, deleting, searching all for free? Also wondering if there's anything like this on Linux.

• How to change color of selected references

  - by user272924

  Visual Studio 2010 highlights all references to the same variable (or class) when your cursor is placed over it. with the theme I use highlighted references are white on white - making them virtually impossible to read. what is the name of "display item" in Options- Environment Fonts and Colors that is responsible for that color? changing Plain Text to a darker one partially solves an issue however that also changes color for lots of other stuff on a screen, so ideally would be to change a background for this type of "selection"..

• Is it impossible to embed Java3D in a way that I don't need to install it?

  - by Kyle

  I'm running a big application and a small part of it includes Java 3D, the problem is many users need to use the code, but it isn't practical for everyone to install Java 3D just to run the application if they aren't even going to use that section of the application. Is it possible through compiling an extra jar, or changing some paths, to include Java 3D in a project without installing it on a system? Or perhaps to manually include any dlls?

• How can I lock the cursor to the inside of a window on Mac OS X?

  - by ZorbaTHut

  I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is there one?

• Indexing one-dimensional numpy.array as matrix

  - by Alain

  I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

• Is passing a struct value to a method by-reference in C# an acceptable optimization?

  - by Arc

  Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?

• Why do I get an Enum constant reference cannot be qualified in a case label?

• Does OpenCL allow concurrent writes to same memory address?

  - by Wonko

  Is two (or more) different threads allowed to write to the same memory location in global space in OpenCL? The write is always changing a uchar from 0 to 1 so the outcome should be predictable, but I'm getting erratic results in my program, so I'm wondering if the reason can be that some of the writes fail. Could it help to declare the buffer write-only and copy it to a read-only buffer afterwards?

• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• Reverse - Link Cell to Textbox

  - by Daniel

  I have 5 worksheets and a textbox on each worksheet. I would like all the textboxes to display the same value, which would be whatever the user enters in the first textbox. So once a value is entered in textbox1 on sheet1, textbox2 on sheet2, etc. will be populated with the same value. I'm looking for something like changing linkedcell =WorksheetName!textbox1 although I'm pretty sure that is incorrect.

• Center current record in DataGridView

  - by Max

  When programmatically changing the current record in the DataGridView is it possible to make it in such way that this record would be centered (vertically) in the grid? When I change the current record it is shown either as the top row or as the bottom row. I'd like it to be in the middle. Would this be possible/simpler in WPF?

  I have a daemon writing to a log file that, eventually, fills up the disk. Is there a way for me to periodically limit the size of the log file without stopping the daemon without changing the code in it? SIGHUP kills the daemon.

• SQL Server 2005 Merge Replication: Under what circumstances would the base snapshot expire?

  - by Gareth

  Obviously changing schema, adding / removing published articles etc expires the snapshot, but is there anything else that would cause the publication to expire? We're seeing a snapshot expiring without any changes to schema or data on the server. If a snapshot is older than the subscription expiration, would that cause it to be expired?

• Overload with different return type in java?

  - by nunos

  So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.
