I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well.
Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.

In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value."
I sometimes see these inter-mixed in the same function. Personally, I prefer the return.
My question is, what is the internal difference, if any, between the two?
About 30 minutes of troubleshooting and it turns out the person who's trying to use my application doesn't have the newest version of the .NET Framework. Is there a way or some KB article which describes a best practice for informing users who are not updated or do not have the framework, etc.
Thanks!
Hello,
.NET 4.0
I am looking for the easiest way to generate a Word document on our server.
Limitations :
Server side
I don't want to install word on the server
Data source is XML
I tried to generate a DOCX with XSLT which is fast and easy but the only way I could find to validate the generated document is to open it with Word and the only error I get when the document is not valid is "Error while opening document". Not very useful.
Any ideas?
Thanks,
Alex
I am writing a C# application and I would like to make calls to different matlab functions simultaneously(from different threads). Each Matlab function is located in its own compiled .net library. It seems that I am only able to call one Matlab function at a time however.
ie, if matlab_func1() gets called from thread1 then matlab_func2() gets called from thread2, matlab_func2() must wait for matlab_func1() to finish executing.
Is there a way to call different matlab functions simultaneously? Thanks.

Hello,
this should be pretty simple but I don't get it. How can I draw a single point in .Net? If I use g.DrawLine(Black,0,0,0,0) nothing is drawn and if I use g.DrawLine(Black,0,0,1,0) a line with 2 dots is used. The same happens with g.DrawRectangle. This has me intrigued.
Thanks in advance.
What's the best way to approach using Mercurial (HG) programmatically from C#?
I will be creating HG repositories, committing, and using other default HG functions. Are there are open-source .NET libraries that would allow me to do this?
Thanks in advance.

Assume you are taking over a legacy .NET app. pre - 3.0
What are the top 5 diagnostic measures, profiling or otherwise that you would employ to assess the health of the application?
I want to use code access security and add code modify group. but I dont see .NET Configuration Tool in the administrator tools.

Thanks in advance.
The question I always wanted to ask and was afraid to, actually - what language is .NET Framework written in? I mean library itself.
It seems to me that it was C and C++ mostly. (I hope Jon Skeet is reading this one, it`ll be very interesting to hear what he thinks about it)
Hi,
I've been using CruiseControl.NET for continuous integration and such. Now I want to be able to deploy projects with it. What is the preferred way of doing this? Do I make a new project which I 'Force Build' to deploy?
I really don't want to deploy on every successful commit.
Please share your thoughts.
What .NET method has this error message: "Object cannot be cast from DBNull to other types"
The stack traces have been stipped from my logs so I'm looking for a starting point.
I'm implementing serial key functionality in my application. User needs to enter at least 64bit number in order to register the application. Because typing number like 9,223,372,036,854,775,807 will take a while I want to compress it a bit. The first guess was to code this number hexadecimally but it still is quite long (0x7FFF FFFF FFFF FFFF).
Is there any standard method in .NET to code this number alphanumerically using for example: digits, upper-case and lower-case characters?
Hi,
I'm writing an application in wpf that uses MVVM. I wondered if I could use ado.net entity data model as a model in MVVM? Is it the same? If not, why?
Thanks for any help.

I need to print the contents of a datagridview, simple text in rows and columns, with GDI+ in .NET to paper.
To do this, I need to iterate over the rows, draw lines, iterate over the columns, calculate width, height, wrap the contents if contents do not fit on one line, etc. This is all possible, but is there a library that simplifies the drawing of tables in GDI+ and abstracts some of the difficulties away?
