• Visual C# Vertically Splitting A Code Window, Is It Possible?

  When editing a C# file, I am able to vertically split the view, either via the IDE's menu bar (Window -> Split) or by clicking and dragging the splitter bar that sits just above the code view's vertical scrollbar. Does anyone know if it's possible to create a vertical splitter bar, such that I can have two views of one file, side-by-side, as opposed to one on top of the other AFAIK there is no command in VS to split a window vertically. I looked in the available commands and there are no options. However for source files you can create a new window using Window ->New Window which creates another window of the same file. You can then use a vertical tab group to give you what you want. Michael Tay ...Show All

• .NET Development Process crash when using SerialPort or Socket objects and thread.Abort

  The easiest way to demonstrate what this error is all about is to compile and run this code: using System; using System.Collections.Generic; using System.Text; using System.Threading; using System.IO.Ports; namespace ST { public class SerialTest { public static SerialPort m_port; public static void ReadFromPort() { byte []buffer=new byte[10]; try { m_port.Read(buffer, 0, 10); } catch (Exception e) { Console.WriteLine("Read thread exception: "+e.ToString()); } } public static void Main() { m_port = new SerialPort("COM1"); m_port.Open(); m_port.ReadTimeout = 100000; Thread thread = new Thread(new ThreadStart(ReadFromPort)); ...Show All

• .NET Development Problem with databindings after removing a row from a DataTable

  I have a DataSet containing 2 DataTables: A and B. The tables are related through a common ‘id’ column, which is a unique column. Table A which is the main table, is displayed by a DataGrid. Table B is displayed by a checkbox and 2 textboxs. (Each control is connected to its matching column through the ‘DataBindings’ property. Everything works fine when I move through rows in the DataGrid, or add a new row. (I see the data of the checkbox and the textboxes is changed properly.) But, when I remove a row from table A, the data I see in the checkbox and the textboxes does not represent the actual data. I don’t know what is wrong, since everything works fine until I delete a row. Can someone help please Table ...Show All

• SQL Server SQL 2005 Mobile loading 2003 Cabs

  I am moving a VS 2003 Pocket PC app to VS 2005 and when I deploy the app from Visuyal Studio 2005 two sqlce cabs are deployed (in addition to the sqlce30 ones) namely sqlce20.dev.ppc.wce4.armv4.CAB and sqlce20.ppc.wce4.armv4.CAB. Now as I have documented in another thread ( SQL 2005 Mobile : The file is not a valid database file ) this gives me problems when I want to access the database being produced by replication. So I'm trying to eliminate the need for these cab files. My pocket PC application uses two of my DLLs the first of which is my Business Objects.

• SQL Server What is necessary to create SDF-Files on desktop legally?

  I want to write a PC application that prepares a SQL Server Mobile Files (.SDF) and sends it to a PocketPC. I get this error message: "SQL Mobile usage is restricted on this platform. To use SQL Mobile, you must install SQL Server 2005, Visual Studio 2005, or the Tablet PC SKU" If I install "SQL Server 2005 Express" the error message disappears and everything works fine. Question: Is it allowed to create SDF-Files if "SQL Server 2005 Express" is installed or is it necessary that my customers buy "SQL Server 2005" It's faster, easer to use, requires little coding on your part and works over HTTP so it can go through firewalls and your SQL Server is not exposed. But, sure, you can use SQL Cli ...Show All

• Windows Forms AutoScroll for Panel control and refreshing while scrolling

  Hi, I'm writing a small app using VS2005 in C#. I put Panel control onto my form and, as child control, another panel inside it. I'd like to see as the content of 'container' panel changes its position during scrolling, but when I set AutoScroll property to 'true' the effect is only seen when I stop scrolling the content (it depends on 'show window contents while scrolling' settings of operating system, on my computer it's set to false). So, to do that, I consumed Scroll event from the container and set location of the child panel using ScrollEventArgs values. Everything works fine until I stop scrolling. After that, scrollbars of the container change their sizes and 'everything breaks', colloquially speaking. I've tried to do something wi ...Show All
