• Visual Studio Express Editions Can i have C# and VB express on my computer?

  The download page for the C# have you remove the .net and other express versions of software. Do i need to remove my VB express and then load the C# and reload the VB express to have them both on my computer Help Please. You need to remove them only if they are beta versions. The final (RTM) versions can coexist on the same machine (VB, C#, C++... in fact all express products) ...Show All

There are things you can do that will maximize the help you will receive and maximize  the value to others.   Often, when you have to ask a question, you’re frustrated and things aren’t working as you think they should work.

• .NET Development How much using should i use?

  Hi,  firstly i started using the using keyword for connections. Later I found (if I'm right) that I can use it on DataReaders as well, without explicitly closing it... and now I have noticed that commands are also disposable, so should I use using ( SqlConnection con = new SqlConnection (connectionString))    using ( SqlCommand cmd = new SqlCommand (commandString, con)        using ( SqlDataReader r = cmd.ExecuteReader())           while (r.Read())             // do something or can I normally let the co ...Show All

• Software Development for Windows Vista quartz.dll SP2 debug

  Just wondering, last time I looked (when DirectShow was included with the DirectX SDK) the quartz debug dll was pre SP2, now in the Platform SDK it does not seem to exist at all. (I have the Windows Server 2003 SP1 SDK). Does a quartz debug dll exist in a later Platform SDK If not, is there going to be one Earlier I really liked the debug dll since I would get information about interfaces that was not released and everything like that. And now when I'm going through another development phase it would be really nice to have all that great functionality back. Using the SP1 version of the dll won't work since I need some SP2 features.

• Visual J# Enum Problem

  How do I convert this from java to j# private enum Status {CONTINUE, WON, LOST}; Thanks for the help. Hi, In VS2003, J# didn't support writing enums though it supported consuming them :(. AS an workaround, 1. You can expose a set of named constants as public, static, fields and then consume them but in this case you may have to change your java code here and there. For Example... class Status { public static final int CONTINUE = 1; public static final int WON = 2; public static final int LOST = 3; } 2. you can declare the enum in a C# class library proj ...Show All

• Software Development for Windows Vista SqlTrackingService & User Events

  Can anybody please point me to a decent sample on the SqlTrackingService I'm passing paremeters through EventArgs in my state machine workflow, but I can't seem to figure out how to get the data back. For example, if I pass a dollar amount when I raise an event, I'd eventually like to be able to recover that value from my application.  I was hoping that the following code would reveal the parameters I had passed (or at least lead me in the right direction).  Unfortunately, however, it has not.  I was hoping that the event arguments could be recovered in the userTrackingRecord.EventArgs property. private void Test() {  &nb ...Show All

• Visual C# Is there a way to create a exe from an exe in C# ?

  I'm fairly new to C# and wanted to ask if anyone knew if it was possible to create an executable from the exectuable made in C#. Basically I want to make a configuration application that will make an executable based on the configurations made by the config app. It's for a application I'm working on that will allow the client app to talk to a custom built content mangement system. The point is to have a dynamic way to create the client app based upon the configurations of the user. It's kind of hard to explain but yeah.  I was able to do this in visual basic 6 but I wanted to know before I get started if this was possible to do in C#. ...Show All

• Visual Basic Master/detail form

  Hi How can I have a master/detail layout on a win form Thanks Regards   Yahya wrote: Hi How can I have a master/detail layout on a win form Thanks Regards Yahya,    First, your data set needs to have a DataRelation set between two of the tables in the set.  This is what allows the master/child relationship to be established.    Once you have that, you can place two grids on your form, and then bind one grid to the parent table.  The child grid, you attach to the relation , not to the child table.  This is what allows only child elements to be disp ...Show All
