<p>I have a Windows Workflow application that uses classes I've written for COM automation. I'm opening Word and Excel from my classes using COM.</p>
<p>I'm currently implementing IDisposable in my COM helper and using Marshal.ReleaseComObject(). However, if my Workflow fails, the Dispose() method isn't being called a... | <p>I can not see what failure you have that does not calls the Dispose() method. I made a test with a sequential workflow that contains only a code activity which just throws an exception and the Dispose() method of my workflow is called twice (this is because of the standard WorkflowTerminated event handler). Check th... | <p>Basically, you should not rely on hand code to call Dispose() on your object at the end of the work. You probably have something like this right now:</p>
<pre><code>MyComHelper helper = new MyComHelper();
helper.DoStuffWithExcel();
helper.Dispose();

</code></pre>

<p>I have been thinking a lot about unit testing and how to improve the readability of the unit tests. I thought why not give a character to the classes in the unit test to clarify what they do. </p>
<p>Here is a simple unit test that I wrote: </p>

<pre><code>private Dave GetDave_With_Wamu_And_Woodforest_AccountsHookedUp()

| <p>I can add Dave to the Wamu and the Woodforest account when Dave is created like this: </p>

FirstName = "Dave";
LastName = "Allen";
// add accounts for Dave
Wamu wamu = new Wamu();

<p>Which Oracle database role will allow a user to select from a table in another schema without specifying the schema identifier?
i.e., as user A- Grant select on A.table to user B;
B can then- "Select * from table" without specifying the 'A'.
One of our databases allows this, the other returns a 'table or view doe... | <p>You can create a synonym for this. Create a synonym named "CoffeeTable" on object "A.CoffeeTable". You can create a public synonym so everyone sees it like this, or just a synonym under user B.</p>
| <p>Brett is right. Synonyms are used for this. In fact there are cases where you do not know what will be the schema name in production. Maybe you use A for some schema name and A is already taken in some Oracle instance.</p>

<p>Are there any Platform agnostic (not CLI) movements to get LINQ going for C++ in some fashion? </p>
<p>I mean a great part of server frameworks around the world run on flavors of UNIX and having access to LINQ for C++ on UNIX would probably make lots of people happy!</p>
| <p><a href="https://github.com/hjiang/linqxx/wiki" rel="noreferrer">Linq++</a> by Hong Jiang looks like a good start. Its syntax is much closer to Linq than CLinq's. <a href="http://pfultz2.github.com/Linq/" rel="noreferrer">Linq</a> by pfultz2 looks interesting, as well, but it needs a C++11 compiler.</p>
| <p>I don't think C++ has the compiler sugar to handle things such as lambda expressions, so no, that's not going to happen.</p>

<p>I am trying to build an website for my college's magazine. I used the "views" module to show a block of static content I created on the front page.</p>
<p>My question is: how can I edit the theme's css so it changes the way that block of static content is displayed?</p>
<p>For reference, <a href="http://www.histor... | <p>The main css file that drives your content is the styles.css file located in your currently selected theme. In your case that means that most of your site styling is driven by this file: /aroda/roda/themes/garland/style.css with basic coloring effects handled by this file:

Your style for the static info comes from the in-line stuff. I am not sure how Drupal generates the page but the place to start looking is for any properties for "ultima-edicao". That is what the surroun... | 5,584 |
<p>I'd like to build an own control, but therefore I need to know if its possible to combine a Textbox event with a Popup more or less like the Datepicker Control.
Or is there a better way to do this than with a Popup?</p>
<p>Greets</p>
<p>Patrick</p>
| <p>Sure you could do this. In fact look at the DatePicker as an example of how you might do that. I'd imagine your control would be a composite of TextBox, Button and Popup controls.</p>
