• Smart Device Development Creating Custom Controls for the Toolbox and .NET 2005

  Hello, I am currently working in Visual Studios 2005, C#. I am attempting to make a custom control that can be used through out many different programs in our mobile department. I have followed numerous on line examples on how to do this, and I can not get any of them to work. My biggest problem is that after the control is created, I add a project to my solution and reference the new control. At that point, the new control is not visible in the Toolbox. If I right click the toolbox and click Show All, I can find the new control, but it is disabled. I have ensured that I am in the new project, that I am on a form, and that other controls ar ...Show All

• Visual C# Confused about some OOP concepts... good resources to learn?

  (I am sorry if this isn't the right forum for this sort of question, but there doesn't seem to be a "General Programming questions" forum here... feel free to move it or delete as necessary) Anyways, I have a lot of programming and C# concepts down, but I'm having a devil of a time coming to grasps with object-oriented programming (I've watched the C# Express videos that deal with it, and the VB.NET ones, and the other ones from LearnVisualStudio.net, but still no luck). I understand the concept of objects, and why it's a good idea to encapsulate methods and such in the object (code reuse ). I also understand about properties an ...Show All

• Smart Device Development Question about System.Data.DataSet in CF 2.0

  Hi there, I'm currently working on an application for the PocketPC-Platform. My tools are VS2005 (C#) and CF 2.0. The input data for my app came as an XML-File from a server-host. We do not want to use SQL-Server Mobile resp. SQL Server Expess-Edition because of higher costs for our customers (client licenses for the server). I'm converting this file to a System.Data.DataSet via the ReadXml()-Method. After ReadXml() has finished my DataSet contains several System.Data.Table-objects. Now my problem: --------------- The data I have to process came from several of this tables (short said an SQL Join-Query). And here my "problem ...Show All

• Software Development for Windows Vista An error occurred while enlisting in a distributed transaction.

  I am trying to wrap some DB calls in a com transaction for testing purposes (make a bunch of calls to the DB, check if they look right, rollback any changes, move on to next test). So far it works fine running against a local SQL Server, but I can't get it to work against our actual development server. I have tried messing around with the Security area of DTC settings on both my machine and the server, allowed inbound and outbound connections, enabled network, turned off my firewall etc. Of course the only message I get when trying to open an ADO.NET connection against our sql server is: An error occurred while enlisting in a dis ...Show All

• SQL Server Is SSIS slower than DTS????!!!!!!

  I am new to SSIS and probably doing some mistake while transferring data from oracle source to oracle destination.   Please guide me..   In our project we need to transfer nearly 80 GB data from old system (Oracle 9i) to new system (Oracle 10 G Release 2). To do this exercise we are testing and comparing performance and cost effectiveness between different tools like SSIS, DTS and SQL * Loader (oracle built in tool).   We have selected one table, which is having 40 fields with 3 million records.

• .NET Development DataFormatString for DateTime column

  I have a GridView with a sortable column bound to a SQL Server datetime field. I want to display the dates as month abbreviation and two digit day. For example, I have a datetime of 2/24/2006 3:25:45 PM and what I want to display instead is Feb 24 or if 2/24/2006 were TODAY 3:25pm Any suggestions A few ideas for you. #1.

• Visual C# Objects stored in a hashtable - by reference?

  Hi, I'm writing an interpreter in c#. For variables I have a system where I have a class representing a variable: class  var { public  Hashtable Children; public   object  Value; }   When a variable is declared, I do something like this: var Temp =  new  var(); Temp.Value = something; VarIndex.Add("variable name",Temp);   However I've found adding the Temp object to the hashtable just adds a reference to the object - if I then use the same Temp object to store another variable in the hashtable, the first variable inherits these characteristics. Is ther ...Show All

• Visual Basic vb6 to VB.Net upgrading Sub Main() error

  Hi everyone.. thanks for taking a peek on my thread. Im upgrading a VB6 application. On its sub main, after it finishes, keeps jumping to other control on different forms. Is there a way to make my project to still go through code just the way VB6 does Sup cgraus.. No.. thats not what I meant. What I tried to say its that in VB6, my application once it finishes the Sub main(), it keeps working with other forms. I understand that in VB6, all forms need to be destroyed so that the application can end. In vb.net after finishing the Sub main, it finishes automatically all the application. How can I handle my code in order to keep workin ...Show All

• Visual C++ PLease help
