C# Dont Reference Sqlreader In Client Portion Then Where?
Oct 30, 2009
Assume I have a form that has say 5 text boxes and I need to pull some data from a database then set those 5 text boxes with that data.So assume I have 3 basic layers: the code behind for a default.aspx page a BLL class that contacts the DAL and a data access layer (DAL)But I've heard and read that the default.aspx page should not know about sqldatareader, in fact you probably dont want to add the sqlclient namesspace to the default.aspx code behind page. [code] Then the BLL would simply call the DAL to call a stored procedure in SQL Server and do a CommandObject.ExecuteReader, get the results pass it back to BLL and BLL would then send it to the code behind page of default.aspx.I can provide full source code if that doesn't make sense. My question is if its bad that default.aspx actually declares and knows about an SQL Data Reader then what is the better way to do this? What datatype should I be using to avoid having an sqldatareader in my interface code ?

I'd like to know after I've executed MySqlReder = MySqlCommand.ExecuteReader() how many rows it returned. If it's one I can continue processing with the data. If it's more than one I need to populate a drop down list box.

i have a WPF application that uses a service reference to a web service.Now i have a GUI component that tracks the progress of this...But i seem to have some sort of bug here, it only occurs on some machines and not often..I start a call with MethodNameAsync and display the progress bar until the matching Completed event occurs.
some times i call 3 different async methods in a row but only the two of them get their Completed event raised so the GUI will be locked and the application has to be restarted.After being totally frustrated a few weeks i found the event AppDomain.CurrentDomain.FirstChanceException, so i hooked up to it and started logging all FirstChanceExceptions..
[Code]...
Fix this temporary by not using async methods and instead using a thread that will call them one by one.. now this is not a elegant solution, i should be able to use the async methods...

I would like to pass to values to a stored procedure. I am using a sqlreader to populate a excel sheet. I need the user to be able to select a range, rather that the whole table.
Dim strSQL As String = "sp_im_select_customerdtl"
Dim data As String = ""
sqlCon.Open()

We are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

Each time I create a program, if I don't change the CPU type to x86 in the Project Properties, Compile, Advanced Compile options, it doesn't work. For example, if I hit the drop down button on a combo box, there will be no data, but after switching to x86, there is data. How does changing the CPU type affect how others (such as when its being graded) view the program? If the program is not run on an x86 system, would it appear to not work then?

I found some threads talking about this.. but when I follow the thread on where to do it.. it must be talking VS2005.. cause on vs2008 in project properties -> application tab-> I dont see View Application Events button. so I assume its moved in VS2008 ? I did find some code I guess to do the same thing.. but I wanted to make sure I do it correct.. since I have an app that a client is running and they keep getting framework exceptions and I have no clue where its coming from.

How can I only add the decimal part of a number to another one?
example: if a number is A = 10.25
Then X = 30
Y = X + 0.25 (Here it added 0.25 which the decimal only NOT 10.25)
Another example, If X = 16.35, A = 102.001
Y = 16.351

I was wondering what the easiest way is to get a portion of text from a string for example, you have:
"example1,example2,example3"
And i need to be able to get all three of the items separate:
"example1"
"example2"
"example3"
The length and number of items will change, I'm using a listview subitem

I am trying to extract the first portion of a string up to the first SPACE or any non-numeric digit.I thought I could do it but the string may contain an alphabet in the front followed by varying digits of numerals, making it more complicated.Here are some examples of the string to be parsed and the expected results:
String[code].....
I would have to use a series of instr statements but the code would be much cleaner using RegEx.

I'm trying to look in the program files for a directory(the gimp directory). I could hard code it but they change the file name and the exe name with the versions. So I only know that the folder contains the word gimp. How do I search for it only knowing a portion of the file name.
My.Computer.FileSystem.FindInFiles(Environment.SpecialFolder.ProgramFilesX86, "gimp", True, FileIO.SearchOption.SearchTopLevelOnly)
This is the code that I've tried but it just doesn't work.

P.S. Is there a way to BringToFront this DrawingImage?
