• C# DLL: Need to know when application is closing

  - by Nick

  Is there a way to monitor when an application that is using the dll closes? The DLL and the application are both C#, neither are Windows Forms. I can check when the main application is closing, but I would like for the DLL to see "hey the program is closing and releasing me, I should do this real quick before I die". Any way to do it? Or am I stuck having the application dish out "do this before you die"?

• pandas read rotated csv files

  - by EricCoding

  Is there any function in pandas that can directly read a rotated csv file? To be specific, the header information in the first col instead of the first row. For example: A 1 2 B 3 5 C 6 7 and I would like the final DataFrame this way A B C 1 3 5 2 5 7 Of corse we can get around this problem using some data wangling techniques like transpose and slicing. I am wondering there should be a quick way in API but I could not find it.

• Starting python debugger automatically on error

  - by jeremy

  This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.

• Is it ok to perform DB operation on UI thread?

  - by user648462

  I am using a database to persist the state of a search form. I am using the onPause method to persist the data and the onResume method to restore it. My opinion is that restoring and persisting state should be a blocking operation so I plan to perform the database operations on the UI thread. I know this is generally discouraged but the operations should be quick and I think if they were done asynchronously they could lead to inconsistent UI behaviour. Any advice

• DeleteSubKey UnauthorizedAccessException

  - by Adam Haile

  I'm trying to write a quick app to modify some registry keys. When I'm browsing via RegEdit, I can modify and delete the keys with no problems. But when I try to use RegistryKey.DeleteSubKey() it throws an UnauthorizedAccessException Is there anyway to gain the privileges to do this? Also, why would there be a problem if my user account obviously has access to make the changes?

• emacs split into 3 even windows

  - by Michael

  Hi all, Quick question: How do I specify the number of characters in a split window? C-x-3 Splits my window into two windows evenly, but a subsequent split will split one of the windows in half. I'd like 3 equal sized windows. The documentation says that I should be able to specify the number of characters for the left buffer as a parameter, but I cant seem to get that to work. Any ideas for syntax? Thanks.

• Testing + production server and syncing MySQL data

  - by Matthew

  I have a web application running on LAMP with a testing server and a production server. Is there a standard practice for keeping the data on the testing server in sync with the production server? The data on the testing server gets out of date pretty quick and I feel like there must be an easier way than just dumping the production server and copying it onto the testing server every so often. It's not important that the data is in total sync, just that the testing server represents the production enviornment as accurately as possible.

• Log to Firefox Error Console from JavaScript

  - by Torsten Marek

  Is it possible to add messages to the built-in error console of Firefox from JavaScript code running in web pages? I know that I there's Firebug, which provides a console object and its own error console, but I was looking for a quick fix earlier on and couldn't find anything. I guess it might not be possible at all, to prevent malicious web pages from spamming the log?

  - by code4life

  I'm having a low-brainwave day... Does anyone know of a quick & elegant way to transform a Dictionary so that the key becomes the value and vice-versa?

• How do I strip local symbols from linux kernel module without breaking it?

  - by Kimvais

  If I do --strip-debug or --strip-unneeded, I have the .ko that lists all function names with nm, if I do just strip foo.ko I have a kernel module that refuses to load. Does anyone know a quick shortcut how to remove all symbols that are not needed for module loading so that people cannot reverse engineer the API:s as easily? PS: For all you open source bigots; this is something that general public will never be using in any case so no need to turn the question into a GPL flame war.

  - by William Leara

  We have an existing Trac installation for an old bunch of source code, and I'm creating a new Trac installation to support a new bunch of source code.

• Converting DTOs to View Models

  - by illvm

  Does anyone know of a good (read: quick to code) method for converting DTOs to View Models or mapping DTO members to View Model members? Lately I've been finding myself writing many conversion and helper methods but this is a very arduous and tedious task. Moreover, it will often needs to be done twice (DTO - View Model, View Model - DTO). Is there a methodology, technique, or technology which would allow me to do this more quickly and efficiently?

• Convert from float to QByteArray

  - by radix07

  Is there a quick way to convert a float value to a byte wise (hex) representation in a QByteArray? Have done similar with memcpy() before using arrays, but this doesn't seem to work too well with QByteArray. For example: memcpy(&byteArrayData,&floatData,sizeof(float)); Can go the other way just fine using: float *value= (float *)byteArrayData.data(); Am I just implementing this wrong or is there a better way to do it using Qt? Thanks
