Meaning for Visual Studio 2008, you're probably using Crystal Reports Version 10.5 or 12

I'm trying to figure out what version of Crystal Reports I have. It's the one that comes in Visual Studio 2008. Does anyone know what it is or how can I check?

What version of Crystal Reports is distributed with VS2008?

The various constructor overloads for [`ReportParameter`][1] only take in a string or string array as acceptable input.

[![ReportParameter Constructor][2]][1]


And the [`ReportParameter.Values`][3] property itself is actually a `StringCollection` in order to force the serialization to happen at compile time.

[![ReportParameter Properties][4]][3]

But you *can pass a null value* with string typing per this thread on [Passing NULL parameter from aspx page to Report Server][5] like this:

    var rp = new ReportParameter("ServiceType_cd", new string[] { null });

Or per this question [Report Viewer: Set null value to Report Parameters having allow null true][6], you can pass in a value like this:

    string str = null;
    var rp = new ReportParameter("ServiceType_cd", str));

How can I put a null value on datetime variable type?
 
I tried to make it nullable value, but I need to use it in `ReportParameter()` method to send it to my report but `ReportParameter()` constructor cannot take a nullable value and the ReportParameter() take just a string values!

passing a null datetime to reportparameter class?

It's to help highlight a line that's been navigated to, due to actions in another VS panel.

For example, if you did a "Find All" and then clicked on one of the results, it would navigate to the match, highlight the line (yours looks to be doing it purple), and also apply that marker to help (further) visually enhance the line you are presumably looking for.

Also, Is there a proper name for this strip?  Is there any documentation on what other types of icons appear here?

![Screenshot][1]

Please let me know if there is any more information you might need that would be diagnostically helpful

What is this Icon in the Visual Studio 2008 debugger strip?

Ok, so I got it done by making an extra line and using a different line for the header and the details section.  It makes it a little harder to maintain, but looks better.

**Designer**:

![Better Designer][1]


**Report**:

![Better Report][2]

I'm using Crystal Reports for VS 2008 and having trouble formatting vertical table lines in the details section.

**Too Short**

When I adjust the height of the line to exactly the height of the bottom of the section:

![Too Short Designer][1]

Then the line doesn't get applied to any items after the first in the list:

![Too Short Report][2]

**Too Long**

If I drag it past the bottom of that section, then it runs amok and fills up the entire page

![Way Too Long Designer][3]

Looks like this:

![Way Too Long Report][4]

**Failed Attempts**

I've tried a bunch of different section and line heights.  I've tried right clicking the line, clicking format object, and checking 'Extend to bottom of Section when Printing'.

I've tried the SO questions [here](https://stackoverflow.com/questions/1756003/), [here](https://stackoverflow.com/questions/8551371/), [here](https://stackoverflow.com/questions/1756003/), and [here](https://stackoverflow.com/questions/12282937/how-to-resize-the-line-objects-in-crystal-reports), and none of them seem to help.
