• .NET Development Is it possible to manually control the assembly version numbers when creating & building a class library?

  Is it possible to manually control the assembly version numbers when creating & building a class library The first two numbers always remain "1.0" The last two numbers seem to increment automatically. How can I change the first two numbers Is it also possible to control all the numbers Many thanks! - Kevin Kevin, Simply change the AssemblyVersion attribute (typically located in the AssemblyInfo.cs/AssemblyInfo.vb/Assembly.cpp) and change the value from "1.0.*" to "1.0.0.0". ...Show All

• Windows Forms The .net UserControl does not work in IE

  Hi, I wrote a simple .NET UserControl to be an ActiveX control inside IE. The UserControl includes a textbox. In the web page, there is another html button to change the ActiveX's textbox value. The problem is: when the html button is clicked, the value of the ActiveX textbox does not change. I don't know why. This is the code for ActiveX user control: ----------------------------------------------------- using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Text; using System.Windows.Forms; using System.Runtime.InteropServices; namespace ActiveXDot ...Show All

• .NET Development Retrieve Single Value from DataTable

  Hiya, I was hoping someone could explain how to retrieve a single value from a DataTable.  I have a DataTable that is populated with a single row and I would like to assign a single value from that row to a textbox.  I have seen plenty examples doing this with a DataSet but NONE using a DataTable directly.  Any info would be greatly appreciated.  Thanks! J.H. Hi, The sample which you have provided is great. I have a doubt in this line of code. Object o = dataTable.Rows[0]["ColumnNameOrIndex"]; Is that we need to give only a single ColumnNa ...Show All

• Visual Studio 2008 (Pre-release) Bug: using a bool property in WHERE doesn't always work

  Hi, I think I've found a bug in the DLINQ expression tree-to-SQL mapper. It's an obvious enough one so I guess you've already fixed it, but I want to make sure it doesn't continue to bug me in the next release . The third sample from 101 LINQ samples, when the condition "!p.Discontinued" is changed into "p.Discontinued", produces a strange SQL like "CONVERT(Predicate,[t0].[Discontinued])". It does work when "p.Discontinued" is the only condition in the WHERE part or if it's prefixed with a "!". I also tried using "p.Discontinued == true", but this doesn't even compile (which I ...Show All

• Windows Forms how to reference a routine or object in the form that contains a usercontrol?

• Visual C# how to convert array into an array of bytes?

  Hi, I'm busy in C# trying to send an array (of string) structure from a server to a client app. I cannot find anywhere how to do this. Im using sockets to do this. but there isnt any method to convert the array into byte[]. Any suggestion would be appreciated. byte[] buffer = System.Text.Encoding.ASCII.GetBytes( "Diego" ); You can use Unicode if your string contains non-ASCII characters. Another handy method is int System.Text.Encoding.ASCII.GetByteCount( string ) if you want to make buffer calculations before the conversion takes place.

• Visual Studio Team System Unable to call a target from overidden CoreCompile

  Hi, I would like to perform a specific target just before each solution is compiled. Unfortunatly, team build performs a build including all solution in an atomic MSBuild call. To correct this behavior, I tought I could overide the default CoreCompile with my own version, in order to call a private target just before each solution is built. However, I can't get CoreCompile to call my target. Wondering what is wrong, I tried overloading CoreClean... and it worked beautifully! Questions: 1. Is there anything special about CoreCompile 2. What is the purpose of the constant _TEAM_BUILD_ defined just before CoreCompile 3. Is the ...Show All

This is very inconvinient, since anybody can forget that a file is shared and harm other projects using it! Thanks for reporting this. I opened a suggestion bug for this, but it's unlikely we are going to change this behavior for VS 2005 release. Hopefully we'll fix it in next realease... Thanks, Alin ...Show All
