In both Visual Basic 6.0 and [VB.NET][1] you would use:

* `Exit For` to break from For loop
* `Wend` to break from While loop
* `Exit Do` to break from Do loop

depending on the loop type. See [Exit Statements][2] for more details.

In case you&#39;re inside a Sub of Function and you want to exit it, you can use :

 

    Exit Sub

   
   or 
  
  

    Exit Function 

`Exit` [construct], and intelisense will tell you which one(s) are valid in a particular place.

We have a junior programmer that simply doesn&#39;t write enough tests.  
I have to nag him every two hours, &quot;have you written tests?&quot;  
We&#39;ve tried:

  - Showing that the design becomes simpler
  - Showing it prevents defects
  - Making it an ego thing saying only bad programmers don&#39;t
  - This weekend 2 team members had to come to work because his code had a NULL reference and he didn&#39;t test it

My work requires top quality stable code, and usually everyone &#39;gets it&#39; and there&#39;s no need to push tests through. We know we can make him write tests, but we all know the useful tests are those written when you&#39;re into it.

Do you know of more motivations?

Does anyone here use VB.NET and have a strong preference for or against using `IsNothing` as opposed to `Is Nothing` (for example, `If IsNothing(anObject)` or `If anObject Is Nothing...`)?  If so, why?

EDIT: If you think they&#39;re both equally acceptable, do you think it&#39;s best to pick one and stick with it, or is it OK to mix them?

IsNothing versus Is Nothing

Suppose I have a stringbuilder in C# that does this:

    StringBuilder sb = new StringBuilder();
    string cat = &quot;cat&quot;;
    sb.Append(&quot;the &quot;).Append(cat).(&quot; in the hat&quot;);
    string s = sb.ToString();

would that be as efficient or any more efficient as having:

    string cat = &quot;cat&quot;;
    string s = String.Format(&quot;The {0} in the hat&quot;, cat);

If so, why?

**EDIT** 

After some interesting answers, I realised I probably should have been a little clearer in what I was asking. I wasn&#39;t so much asking for which was quicker at concatenating a string, but which is quicker at **_injecting_** one string into another.

In both cases above I want to inject one or more strings into the middle of a predefined template string.

Sorry for the confusion

Is String.Format as efficient as StringBuilder

I need to generate a random integer between 1 and n (where n is a positive whole number) to use for a unit test. I don&#39;t need something overly complicated to ensure true randomness - just an old-fashioned random number.

How would I do that?

I am familiar with nunit for unit testing of the business layer however I am looking now to automate the test of the win forms gui layer.  

I have seen [watin][1] and the watin recorder for automating tests on web application by accessing the controls and automating them. However I am struggling to find a watin equivalent for windows forms (written in c# or vb.net) preferably that is open source.    

Does one exist or are all products based on recording mouse and keyboard presses?


**Update:** I have looked at this [blog post on white][2] and it seems the sort of thing I am looking for. The blog post raises some issues but as white is only in version 0.6 these may be resolved. Be interested if others have used white or any others for comparison.

In Visual Basic, is there a performance difference when using the `IIf` function instead of the `If` statement?

In a C# (feel free to answer for other languages) loop, what&#39;s the difference between `break` and `continue` as a means to leave the structure of the loop, and go to the next iteration?

Example:

    foreach (DataRow row in myTable.Rows)
    {
        if (someConditionEvalsToTrue)
        {
            break; //what&#39;s the difference between this and continue ?
            //continue;
        }
    }

Today I had a coworker suggest I refactor my code to use a label statement to control flow through 2 nested for loops I had created. I&#39;ve never used them before because personally I think they decrease the readability of a program. I am willing to change my mind about using them if the argument is solid enough however. What are people&#39;s opinions on label statements?

Should I avoid using Java Label Statements?

Let&#39;s say I have the following simple table variable:

    declare @databases table
    (
        DatabaseID    int,
        Name        varchar(15),   
        Server      varchar(15)
    )
    -- insert a bunch rows into @databases

Is declaring and using a cursor my only option if I wanted to iterate through the rows? Is there another way?

How to get a counter inside xsl:for-each loop that would reflect the number of current element processed.  
For example my source XML is

    &lt;books&gt;
    	&lt;book&gt;
    		&lt;title&gt;The Unbearable Lightness of Being &lt;/title&gt;
    	&lt;/book&gt;
    	&lt;book&gt;
    		&lt;title&gt;Narcissus and Goldmund&lt;/title&gt;
    	&lt;/book&gt;
    	&lt;book&gt;
    		&lt;title&gt;Choke&lt;/title&gt;
    	&lt;/book&gt;
    &lt;/books&gt;

What I want to get is:

    &lt;newBooks&gt;
    	&lt;newBook&gt;
    		&lt;countNo&gt;1&lt;/countNo&gt;
    		&lt;title&gt;The Unbearable Lightness of Being &lt;/title&gt;
    	&lt;/newBook&gt;
    	&lt;newBook&gt;
    		&lt;countNo&gt;2&lt;/countNo&gt;
    		&lt;title&gt;Narcissus and Goldmund&lt;/title&gt;
    	&lt;/newBook&gt;
    	&lt;newBook&gt;
    		&lt;countNo&gt;3&lt;/countNo&gt;
    		&lt;title&gt;Choke&lt;/title&gt;
    	&lt;/newBook&gt;
    &lt;/newBooks&gt;

The XSLT to modify:

    &lt;xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;http://www.w3.org/1999/XSL/Transform&quot;&gt;
    	&lt;xsl:output method=&quot;xml&quot; version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; indent=&quot;yes&quot;/&gt;
    	&lt;xsl:template match=&quot;/&quot;&gt;
    		&lt;newBooks&gt;
    			&lt;xsl:for-each select=&quot;books/book&quot;&gt;
    				&lt;newBook&gt;
    					&lt;countNo&gt;???&lt;/countNo&gt;
    					&lt;title&gt;
    						&lt;xsl:value-of select=&quot;title&quot;/&gt;
    					&lt;/title&gt;
    				&lt;/newBook&gt;
    			&lt;/xsl:for-each&gt;
    		&lt;/newBooks&gt;
    	&lt;/xsl:template&gt;
    &lt;/xsl:stylesheet&gt;

So the question is what to put in place of ???. Is there any standard keyword or do I simply must declare a variable and increment it inside the loop?

As the question is pretty long I should probably expect one line or one word answer :)

Counter inside xsl:for-each loop

Apparently xrange is faster but I have no idea why it&#39;s faster (and no proof besides the anecdotal so far that it is faster) or what besides that is different about

    for i in xrange(0, 20):

I&#39;m looking for a decent sort implementation for arrays in VBA. A Quicksort would be preferred. Or any other [sort algorithm][1] other than bubble or merge would suffice.

Please note that this is to work with MS Project 2003, so should avoid any of the Excel native functions and anything .net related.

I always read that it is recommended to set objects to nothing, once I am done with them. But I normally use them only in functions inside forms.

Isn&#39;t the reference lost and memory released when the function scope is left, regardless of setting objects to Nothing? 

i.e. is it really necessary to do:

    Set db = Nothing
    Set record_set = Nothing


Is there a need to set Objects to Nothing

The docs say that calling sys.exit() raises a SystemExit exception which can be caught in outer levels.  I have a situation in which I want to definitively and unquestionably exit from inside a test case, however the unittest module catches SystemExit and prevents the exit.  This is normally great, but the specific situation I am trying to handle is one where our test framework has detected that it is configured to point to a non-test database.  In this case I want to exit and prevent any further tests from being run.  Of course since unittest traps the SystemExit and continues happily on it&#39;s way, it is thwarting me.

The only option I have thought of so far is using ctypes or something similar to call   exit(3) directly but this seems like a pretty fugly hack for something that should be really simple.

Is there a way to prevent a SystemExit exception raised from sys.exit() from being caught?

I have a simple Python script that I want to stop executing if a condition is met.

For example:

    done = True
    if done:
        # quit/stop/exit
    else:
        # do other stuff

Essentially, I am looking for something that behaves equivalently to the &#39;return&#39; keyword in the body of a function which allows the flow of the code to exit the function and not execute the remaining code.




How do I abort the execution of a Python script?

I have a question regarding launching new activities. It boils down to this.
I have 3 tabs on a view
 

    A) contains gMap activity
     B) camera activity
     C) some random text fields.

Requirement is that the application runs in Portrait mode. 

 All 3 tabs work as expected w/ the exception of the Camera Preview Surface (B). It is rotated 90 degrees. They only way to make it correct is to set the app to landscape which throws all my tabs around, and is pretty much unworkable.

 My solution is this : replace 

 my camera activity with a regular activity that is empty w/ the exception of 

    Intent i = new Intent(this,CameraActivity.class);
    	startActivity(i);

This launches my CameraActivity. And that works fine. I had to do a linear layout and include 3 images that look like real tabs, so I can try and mimic the operation of the tabs while rotating the screen to landscape and keep the visuals as portrait.
The user can click one of the images(buttons) to display the next tab. This is my issue. It should exit my &#39;camera activity&#39; returning to the &#39;blank activity&#39; in a tab, where it should be interpreted to click the desiered tab from my image. 

The main thing is, when it returns, it returns to a blank (black) page under a tab (because it is &#39;empty&#39;). How can I capture the return event back to the page that called the activity, and then see what action they performed? 

I can set an onclicklistener where I can respond to the fake tabs (images) being clicked to exit out of the camera activity. On exit, the tab should update so that is where you return. any Suggestions?
