• Visual Basic Skinning...

  How do you skin a program so it doesnt use the default windows skin. Are we talking windows or web application. Web Applications - isn't that sort of what master pages are about. http://builder.com.com/5100-6371-6057134.html For Windows application - Probably the easiest way would be to use a third party component to do this for you and add the appropriate UI for whatever skin you want to implement. If you want to create the skins yourself, then maybe something like this is a good start. But I dont think by default VB contains a skinning component. ...Show All

• Windows Forms GridView DeleteCommand Firing Twice

  I Have a gridview with a command button for delete defined. On the Datasource for the grid I have a DeleteCommand that runs a stored procedure that takes the ID field defined in grid view control. When the delete command is selected in the gridview the deletecommand stored procedure is called twice with the same ID (I have traced this). I have removed all delete events from the gridview and datasource. I have a FormView that has a selectcommand using the GridViews primary ID. I have autoeventwireup set to true. There is no code being ran before or after deletion. I did have a refresh procedure being ran after delete. Whe ...Show All

• Visual C# Casting an enumeration that has a defined type..

  public enum foo : ushort { foo, bar } ushort test = foo.bar; Cannot convert from 'Test.foo' to 'ushort' Sure, I can make variable of type foo, but I'm encoding the value to a network stream, so I want it as a ushort. The thing is, I specifically told the compiler the enum is of type ushort, so why do I have to typecast it cgraus wrote: Well, one thing I like about C# is strongly typed enums. If I were you, I'd be using one enum for both, assuming they both represent the same thing and have the same values ( which your statement seems to me to imply ). Unfortunately, ...Show All

• Visual C++ "Correct" Workerthread Termination

  Hello, I have used worker threads for a long while and yet always had and still have problems with the "correct" way such threads should be killed for premature termination. They may have files open, are in the process of allocating global memory or doing any number of other things. The closest I got to "correct" is to signal the worker thread through it's priority if it's services are not required anymore for termination prior to it's full execution. Except the code then starts to look messy with CheckForKill()s all over the worker thread code. What is the "best correct" method to do this and yes, I am aw ...Show All

• .NET Development Xml Serialization breaks OO encapsulation?

  Only public fields / properties are xml-serializable, as I tested and searched on web. What happens if I have a class containing read-only properties, or internal states (private fields) that are not public Do I have to compromise the encapsulation concept in order to get it serialized Blair Allen Stark wrote: XML is just a simple data interchange for passing the public data an object presents back and forth. Almost by definition it needs to be read/write. And XML makes no specification as to how the consumers are to contain the data. Yes, we typically write our own suppliers and consumers for both sides, but that is really j ...Show All

• SQL Server ODBC Data Source error

  As other contributors, all I am trying to do is import data from an ODBC source (spelled 'non-Microsoft data source') into a SQL 2005 table. I can easily do this in SQL 2000 with DTS, but when I use the same DSN in VS 2005 it doesn't work. I created an integration project, and made a connection in Connection Manager to the DSN and clicked Test Connection. It succeeded, or so it claimed.

• .NET Development SerialPort Class Help DataReceived

  I'm using the DataReceived from the V.2 .NET SerialPort class. I'm communicating with a microprocessor board and i can write to it fine. I'm having trouble reading from it. It sends a single byte at a time without an EndCharacter. I can see the byte being sent on my oscope and with an older Turbo Basic program it does read the byte. My problem is that my DataReceived event isn't being thrown. I have my ReceivedBytesThreshold set to 1 and i still can't see anything.
