  • SQL Server 2008 takes up a lot of memory?

    - by Ahmed Said
    I am conducting stress tests on my database, which is hosted on SQL Server 2008 64-bit running on a 64-bit machine with 10 GB of RAM. I have 400 threads. Each thread queries the database every second, but the query time does not take time, as the SQL profiler says that, but after 18 hours SQL Server uses up 7.2 GB of RAM and 7.2 GB of virtual memory. Is this normal behavior? How can I adjust SQL Server to clean up unused memory?

  • mod_rewrite browser trying to get content from non-existant dir

    - by humgl
    I have my mod_rewrite set up so that it redirects all requests that aren't targeting existing files or directories to index.php?req=* where * is the request. Works all fine but when I send the browser to something like this: http://myurl/A/B/C The browser tries to find all images, stylesheets in the non-existing folder C. How can I make the browser to look in / instead of the 'virtual' directory? Do I have to put an absolute path everywhere?

  • Does EGit mandate installing JGit?

    - by Souper
    After using Git from the command line for a while, I am ready for the convenience a GUI plugin (for Eclipse) can offer. However, I prefer a Git plugin similar to to MS Visual Studio's Git Source Control Provider which is only a wrapper around the already installed msysgit. I really don't want two different Git implementations accessing the same repository. EGit sounds perfect - if it can use the already installed msysgit in my PC. But can it?

  • looser throw specifier for in C++

    - by ML
    I am getting an error that says: error: looser throw specifier for 'virtual CPLAT::CP_Window::~CP_Window()' On the destructor, I have never heard of this before and some Google Searches say this might be a GCC 4 problem, which I would not be sure how to work around since I need GCC 4 to build a Universal Binary. My Environment: OS X 10.6, XCode 3.2.2, GCC 4 to build a universal binary. What is the issue?

  • How do you automatically remove the preview window after autocompletion in Vim?

    - by Ben Davini
    I'm using omnifunc=pythoncomplete. When autocompleting a word (e.g., os.), I get the list of eligible class members and functions, as expected, as well as a scratch buffer preview window with documentation about the selected member or function. This is great, but after selecting the function I want, the preview window remains. I can get rid of it with ":pc", but I'd like it just to automatically disappear after I've selected my function, a la Eclipse. I've played around with "completeopt" but to no avail.

The virtual machine has VMware Tools installed, does that provide a .NET API for hooking events?

  • ASP.NET Hosting and routing

    - by V-Man
    Is it possible to host 2 asp.net projects off one ip address? I don't have a domain name just an ip number. I'm running IIS7. The first project runs and displays fine over the web by simply typing in the ip address into the browser but I'm having trouble accessing the second. Currently both projects have virtual directories in IIS7. Help is greatly appreciated. Thx

  • Is there any way to identify a unique user in Flash/Actionscript 3?

    - by VGambit
    I'm trying to make a vote/poll application in Flash using Actionscript 3. Is there any way to generate a specific ID that is unique to each user? The only other option I can think of is using the IP address, which is less than ideal in many cases (college campuses, shared Internet access, etc.). It needs to be the same number every time it is run on the same PC, but different for each user.

  • Setting of IIS memory settings for ASP.NET

    - by user54064
    We are running an ASP.NET app on a web server with 4GB+ of memory in IIS 6. After reading many articles, it states that we need to set the "maximum memory used" for the Application Pool to 800mb to eliminate the "out of memory exceptions" that are happening for us. However, what should the "maximum virtual memory" in the Application Pool be set to? I can't find information as to what that should be set to.

  • UIFileSharingEnabled use folders

    - by Ali Shafai
    I want to allow users add files to the application document folder, so I used the iTunes file sharing. The problem is they can only add single files with a flat structure. I want to drag and drop whole folder (even with sub folders) and keep the structure. Questions I have: is it possible with iTunes file sharing? if not, is there an open source project that helps me with writing a pc side app that talks to the iPhone side app and pushes the files into it?
