If you would like to use an enumeration, try the following:

    Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData)

Using this technique, you can also find all other Window&#39;s file paths (i.e Program Files, My Documents, etc).

`Environment.GetEnvironmentVariable(&quot;LocalAppData&quot;)` for C#, since Visual Studio isn&#39;t a language, unless you&#39;re looking to get that variable in one of the VS dialogs or something.

`Environment.SpecialFolder.LocalApplicationData`

I haven&#39;t got my hands dirty yet with neither [CouchDB][1] nor [MongoDB][2] but I would like to do so soon... I also have read a bit about both systems and it looks to me like they cover the same cases... Or am I missing a key distinguishing feature?

I would like to use a document based storage instead of a traditional RDBMS in my next project. I also need the datastore to 

- handle large binary objects (images and videos)
- automatically replicate itself to physically separate nodes
- rendering the need of an additional RDBMS superfluous

Are both equally well suited for these requirements? 

Thanks!

In order to write more concisely, rather than do this:

    test_value = method_call_that_might_return_nil()
    if test_value
      do_something_with test_value
    end

I&#39;ve been assigning in the conditional:

    if test_value = method_call_that_might_return_nil()
      do_something_with test_value
    end

Is this bad style? The still-more-concise syntax:

    do_something_with test_value if test_value = method_call_that_might_return_nil()

is not allowed, as discussed [in another SO question][1], and will remain that way in 1.9, according to Matz (http://redmine.ruby-lang.org/issues/show/1141).

Given the possible confusion of assignment and comparison, does this make it too hard to read the code?

How do I get %LocalAppData% in c#?

I am trying to persist string from an ASP.NET textarea. I need to strip out the carriage return line feeds and then break up whatever is left into a string array of 50 character pieces.

I have this so far

    var commentTxt = new string[] { };
    var cmtTb = GridView1.Rows[rowIndex].FindControl(&quot;txtComments&quot;) as TextBox;
    if (cmtTb != null)
      commentTxt = cmtTb.Text.Length &gt; 50
          ? new[] {cmtTb.Text.Substring(0, 50), cmtTb.Text.Substring(51)}
          : new[] {cmtTb.Text};

It works OK, but I am not stripping out the CrLf characters. How do I do this correctly?


How can I remove &quot;\r\n&quot; from a string in C#? Can I use a regular expression?

I am having trouble figuring out how to break out of a loop that contains a switch statement.  Break breaks out of the switch, not the loop.

There is probably a more elegant solution to this.  I have implemented a flag that starts out as true and gets set to false and ends the loop.  Can you offer a better solution?

Background: this code is used in a bar code workflow system.  We have PocketPCs that have bar code scanners built in.  This code is used in one of those functions.  It prompts the user for different pieces of data throughout the routine.  This piece allows them to scroll through some inventory records displaying that info on the PocketPC terminal (paged results) and allows them to enter &quot;D&quot; for Done, &quot;Q&quot; to quit.

Here is the current C# example that needs to be improved:

    do
    {
        switch (MLTWatcherTCPIP.Get().ToUpper())
        {
            case &quot;&quot;: //scroll/display next inventory location
                MLTWatcherTCPIP.TerminalPrompt.ScrollBodyTextDown();
                break;
            case &quot;P&quot;: //scroll/display previous inventory location
                MLTWatcherTCPIP.TerminalPrompt.ScrollBodyTextDown();
                break;
            case &quot;D&quot;: //DONE (exit out of this Do Loop)
                // break; // this breaks out of the switch, not the loop
                // return; // this exists entire method; not what I&#39;m after
                keepOnLooping = false;
                break;
            case &quot;Q&quot;: //QUIT (exit out to main menu)
                return;
            default:
                break;
        }
    } while (keepOnLooping);

Here is an example of code that does this in VB.NET

    Do
        Select Case MLTWatcherTCPIP.Get().ToUpper
            Case &quot;&quot; &#39;&#39;#scroll/display next inventory location
                MLTWatcherTCPIP.TerminalPrompt.ScrollBodyTextDown()
            Case &quot;P&quot; &#39;&#39;#scroll/display previous inventory location
                MLTWatcherTCPIP.TerminalPrompt.ScrollBodyTextUp()
            Case &quot;D&quot; &#39;&#39;#DONE (exit out of this Do Loop)
                Exit Do
            Case &quot;Q&quot; &#39;&#39;#QUIT (exit out to main menu)
                Return
        End Select
    Loop

Thanks,

I&#39;m setting up TeamCity as my build server. 

I have my project set up, it is updating correctly from subversion, and building ok.

So what&#39;s next?  

Ideally, I&#39;d like to have it auto deploy to a test server, with a manual deploy to a live/staging server.

What&#39;s the best way to go about this?

Since I am using C#/ASP.Net, should I add a Web Deployment project to my solution?

How to deploy after a build with TeamCity?

Say I have these values in a database table

    id = 1
    StartDate = 1/3/2010
    EndDate =  1/3/2010
    
    id = 2
    StartDate = 1/3/2010
    EndDate = 1/9/2010

Now I have so far this orderby for my linq

    var hold = MyList.OrderBy(x =&gt; x.StartDate).ToList();

I want to order it however also using the end date.

Like so the order I would want this in as

    id 2
    id 1

So `endDates` that are greater go first. I am not sure if I need to change this to use some compare function or something.

How to use orderby with 2 fields in linq?

Suppose that you have a lengthy string (&gt; 80 characters) that you want to spread across multiple source lines, but don&#39;t want to include any newline characters.

One option is to concatenate substrings:

	string longString = &quot;Lorem ipsum dolor sit amet, consectetur adipisicing&quot; +
		&quot; elit, sed do eiusmod tempor incididunt ut labore et dolore magna&quot; +
		&quot; aliqua. Ut enim ad minim veniam&quot;;

Is there a better way, or is this the best option?

Edit: By &quot;best&quot;, I mean easiest for the coder to read, write, and edit. For example, if you **did** want newlines, it&#39;s very easy to look at:

    string longString =
    @&quot;Lorem ipsum dolor sit amet, consectetur adipisicing
    elit, sed do eiusmod tempor incididunt ut labore et dolore magna
    aliqua. Ut enim ad minim veniam&quot;;

I am wondering if there is something just as clean when you **don&#39;t** want newlines.

In C#, what&#39;s the best way to spread a single-line string literal across multiple source lines?

What&#39;s the quickest and easiest way to get the Min (or Max) value between two dates? Is there an equivalent to Math.Min (&amp; Math.Max) for dates?

I want to do something like:

     if (Math.Min(Date1, Date2) &lt; MINIMUM_ALLOWED_DATE) {
          //not allowed to do this
     }

Obviously the above Math.Min doesn&#39;t work because they&#39;re dates.

I have a webpage hosted on a Windows box that I need to assure gets loaded at least once/day. My current plan is to create a scheduled task that opens Internet Explorer and hits the URL:

    &quot;C:\Program Files\Internet Explorer\iexplore.exe&quot; myurl.com/script_to_run_daily.aspx

This was simple to setup and works fine, but it strikes me as a hack because Internet Explorer actually has to open and hit this URL. I don&#39;t need any input back from this page, it simply stores cached data in files when it&#39;s hit.

Is there a slicker way of doing this? In case it matters, this is a VB.net site.

Thanks in advance!

I created a windows application developed in .NET 3.5 in a 32 bit Windows 2008 server. When deployed the application in a 64 bit server it shows the error &quot;Microsoft.Jet.OLEDB.4.0&#39; provider is not registered on the local machine &quot;.

So as a solution to this issue, i have changed the build property of the project to X86, so that it will build in 32 bit mode, and rebuild the project in the 32bit machine. But, the same project uses other DB drivers (DB2, SQL etc.) to connect to other databases. So when i deployed my app again in the 64 bit OS, it throws the exception &quot; Attempted to load a 64-bit assembly on a 32-bit platform. &quot;

I am using the Microsoft.Jet.OLEDB.4.0 driver to read and write to the Excel (.xls)

Is there a built-in way of getting the full URL of an action?

I am looking for something like `GetFullUrl(&quot;Action&quot;, &quot;Controller&quot;)` that would return something like `http://www.fred.com/Controller/Action`.

The reason I am looking for this is to avoid hardcoding URLs in automated emails that are generated so that the URLs can always be generated relative to the current location of the site.
