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.
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
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!
Which name is more consistent with .NET naming standards for properties and methods?

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.
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.
I'm not getting to hang of the entire FormAuthentication thing. Is there an up-to-date tutorial somewhere? I found this one, but it a bit old and the syntax doesn't match recent Asp.Net MVC.
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?
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?
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.

I have an ASP.NET page which utilizes jQuery for an autocomplete-type scenario. The jQuery tucks the actual selected values into a hidden field it creates on the fly, but for some reason I cannot get the value of that standard HTML field on postback by calling Request.Form["HiddenFieldName"]. I can see it by ordinal in the Request.Form object, but if I add/remove controls it will break. Any suggestions?
I know that whenever you add/remove/modify any file in the "App_Code", "App_GlobalResources", and "bin" directories that ASP.NET will recompile and essentially restart the application.
My question is : "What happens to any threads currently executing durring the change?"
Do they finish? Is a Thread.Abort Exception thrown?
What happens if the application itself makes a change in any of those directories?
I am building a search page in asp.net 3.5. Search takes a bit of time (few seconds to few minutes). Current I use AsyncMethodCaller to call Search method. AsyncMethodCaller method stores search results in Session. I user Ajax timer to check if Search method finished and then display results.
What would be the best way to implement this scenario?
when i debug our website then he works fine. but when i want to refresh that i refresh it in browser i see that my asp.net development server is automatically closed before my refresh so browser tell me that " Unable to connect". why are development server is automatically closed without any reason.
Are you know why development server is automatically closed.
The site im working on is an Ajax enabled ASP.net/C# project and i have a URL like this:
http://localhost:2531/(S(lfcvqc55wkabpp55o1x4pvq5))/Logon.aspx
How do you get rid of the (S(lfcvqc55wkabpp55o1x4pvq5)) portion of the URL? I have a feeling its a web.config parameter however I'm not really sure what you call this part, GUID, Session ID?
I know this is a terrible way of doing things, but it's for an internal app where security is no issue.
Basically, an old group created a php page with a drop down and this drop down is populated with entries from a DB. The DB owner is currently absent and for the sake of time, I would just need something that turns the entries in that drop down, always at the same url with the same ID every load into a List. Is there a quick, painless way to do this in .NET?
