• Worf building project having many main class

  Hi I want to build a project which contains classes each of them having own main method. Is it possible for me to compile the project without specifying starting class(class with main) (i can specify starting class during execution). This is possible with Eclipse IDE used for Java. The starting class is need to be specified only during execution. Could any body help me in this Thanks Natarajan Arumugam. You can create a new class with its own main function and set that to be the starting main and then have that new main call the old ones appropriately, provided they are declared as (or you can change their declaration to be)  public  or internal  (if comp ...Show All

• suresh babu krishnappa How do I write text to an RTF Text Box

  I'm adapting the UsingMenusStatusStripsToolStrips example (in CS101 samples) which puts some example text in an RTF box and allows a user to type in the box. Instead I have a class that receives text via an IP socket and I want to place this text in the box. I tried adding a public "WriteToForm" method in Form1.cs, but code in the IP listner object can't access this method. Is there a trick to this Thanks Scott Because I am calling this from another object (class). I've created my IP listner object in a separate thread as it just listens for and processes messages. That's works fine. If I remove "static" from the above Form_write method, I get an error at the original call to Form_write - " An obje ...Show All

• Sanje2v static method - Is there any workaround?

  I think most know we cannot declare a static anything in an interface. However, let's say I have this: public sealed class MyClass { private MyClass(string someText) { m_someModifiedText = someText; } private readonly static m_someModifiedText; public static MyClass Create( string someText ) { string modifiedText= ModifyText(someText); return new MyClass(someText); } private string ModifyText(string someText) { string modifiedText = someText; //do something to modify text return modifiedText; } public static string UsefulText { return m_someModifiedText; } } Now, this "sample" is just to keep it simple, but PLEASE just consider the concept rather than what the ...Show All

• Sam Gentile MVP - Solutions Arch Importing C++ Express project to C# express?

  Hi, I am new here and I am wondering if it is possible to import C++ express project into C# express ... Best Regards, Johney In short... Managed Code is where a program or other code is not executed directly by a computer’s processor (as most applications are) but instead executed within the context of a virtual machine or other code that acts as an intermediary between the application and the overall environment (memory, cpu, etc). .NET is a platform for building applications in Managed Code, although the term isn’t used as much in languages such as C# or VB.NET as there really isn’t an unmanaged version of either... C++ on the other hand you can build native (unmanaged) applications, unman ...Show All

• leonlai Running two services in same VSTS project

  Hello... I have created two c# windows services in the same VSTS project. They each have their own installers, and installs fine in the windows service list.

• James Nelson the Second Why doesn't IList have a BinarySearch method

  IList<> does not have a BinarySearch method, but List<> does. Is there any reason for that The reason I found out about IList<> not having a BinarySearch method is because I initially wanted to do a binary search on a SortedList<> SortedList<>. Strangely enough, SortedList doesn't have a BinarySearch() function, so I looked in SortedList<>.Keys. That's an IList, which also does not have a BinarySearch() method. I looked up List<> to confirm, and it does have a BinarySearch() method. I've worked around this using (SortedList<>.Keys as List).BinarySearch(), and that compiles, but I have not tested it yet. So, there might be an easy work around, but I just can't think of a good reason why ...Show All

• Susand is there a readline library available for c#?

  Hi, For a java project once upon a time I used a version of gnu readline ( http://tiswww.tis.case.edu/~chet/readline/rltop.html) to help with console input. It was very handy as it allowed the user to edit command lines as typed in, use tab completion, use the up arrow to repeat the previous command, etc. Is there anything similar for c# I'm running on the .net 1.1 framework. Thanks, Beth Yes, I had come across the Mono-Readline project too, but my initial impression was that it wasn't quite what I was looking for. I was hoping that I wouldn't have to go down the route of building what I need, although it really shouldn't be too hard to get a mimimal system going. The article was intere ...Show All

• wanda Don't know what type of issue of My Visual Studio 2005 Team suit IDE

  I got a problem of my IDE. If I create a new C# website project using either File System or IIS project, when the solution was created, I opened codebehind file, the IDE produced a lot of erros for the syntax (by default). when I pointed to that error, it's said "'class' statment must end with a match 'end class'", it seems that the IDE use VB syntax to check my C# codebehind file.
