• C code to round numbers

  - by webgenius

  Is there any way to round numbers in C? I do not want to use ceil and floor. Is there any other alternative? I came across this code snippet when I Googled for the answer: (int)(num < 0 ? (num - 0.5) : (num + 0.5)) The above line always prints the value as 4 even when float num =4.9. Please suggest a solution.

• What is the correct way to create a single instance application?

  - by Nidonocu

  Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

• Why do toast notifications die if delayed?

  - by ubershmekel

  I'm not sure this is the exact cause of my problem but I'll explain the 2 symptoms I noticed: If I put a break point on a Toast.makeText(..).show(), step over, then wait a few seconds before running, the toast will never appear. I have a location callback that tries to show a toast, but it never appears. Maybe I'm doing something else wrong, this is the line in question in my open source distress signal app. Any help or pointers would be appreciated, --uber

  We have eight Xeon (i7) cores and 16 gig of RAM on our SSIS box. We have about 200 image files we want to convert using a command line utility every day. Currently the process is using Adobe Photoshop and droplets (very manual, taking upwards of two hours a day) Using SSIS hot folders, is there a way to execute up to eight conversions at once? Is there any way to tell a process completed or execute code upon it's completion?

• How do I temporarily disable AppStats in my Google App Engine application?

  - by quikchange

  I recently configured my app to use the new AppStats feature of GAE. However, while debugging it, the extremely verbose logging from AppStats is annoying & I'd like to disable it while I'm debugging and then turn it back on later. Surely there is a single line I can add to or modify in a config file that will let me do this.

• How to create a "copy" of SQL Server transaction log file

  - by Salman A

  I want a copy of SQL Server transaction log file for "raw" analysis. What is the safest way to get a copy of that file without shutting down the database and disturbing the existing log/backups/backup schedules and just about everything. FYI, Its a SQL Server 2000 database server and I can see the log file (its about 4GB in size) and I cannot copy it as is; I get the "access denied" error when copying from explorer or command line.
