View 1 RepliesUse MS's VB Express And Stuff?
Jan 17, 2010I've been looking for some programming languages, and I've read about the basics of Python and C++, but I'm more interested in Visual Basic But! Everywhere I look, I only find tutorials about how to use MS's Visual Basic Express and stuff, not how to code, not tutorials about the code syntax, how to declare variables and these essential things.Does anyone here has a good tip about learning the basics of VB? And not how to use VB Express/Full edition I can insert a new button but I have no idea on how to make it work, what's the point of it?
EDIT: Oh and another thing.I was playing around VB, creating a simple user interface with buttons, and I've noticed that the code doesn't change when I update the button's or other objects' Name property in the Designer window... shouldn't the code update itself with the new objects names?

View 8 RepliesDrop Down Box And Other Stuff In ASP.NET With (VS 2008)
Apr 13, 2010I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions:
1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page.
2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I tried to use just a text box but that isn't working right.

View 1 RepliesC# - Finalizers Accessing Managed Stuff
Jul 26, 2010I am well aware that finalizers are typically used to control unmanaged resources. Under what circumstances may a finalizer deal with managed ones? My understanding is that presence in the finalizer queue will prevent any object, or objects strongly referenced thereby, from being collected, but it will not (of course) protect them from finalization. In the normal course of events, once an object is finalized it will be removed from the queue and any objects it references will no longer be protected from collection on the next GC pass. By the time a finalizer is called, the finalizers may have been called for any combination of objects referred to by the object; one cannot rely upon finalizers being called in any particular sequence, but the object references one holds should still be valid.

Database Primary Key Won't Hide And Some Other Stuff?
Aug 17, 2011So Im making a program with 2 different data tables where different columns from those tables are used in different tabs in the same form. This all works good and well so far, but I have one issue which just drives me mad, and a couple minor ones.
1. I have an ID column in each data table marked as Primary Key, Unique and Identity. Problem is that even if I choose to hide this column it just randomly decides if it actually is visible or not. Most often its visible. I dont get it, doesnt this function work? Do I use it wrong? Im not using any code for this, just right click on the data grid, press Edit Columns... And change the Visible to False. It works for all other columns all the time as far as I can tell, but for my ID column its just random.
2. Im wondering if its possible to align the text in some of the columns of my data table to the right, note I only want some of them, not all of them.
3. Is it possible to do maths with the values from the columns in a table on the same row? Like for example having column 3 = column1 + column2?

View 3 RepliesRegEx - Pattern For Stuff In Parenthesis
Dec 17, 2009I have strings like:
1. Three (3) 10,000 gallons underground gasoline storage tanks.
2. Equip ID: (23-1)
I want to extract the '3' and the '23-1' and from the strings. I can rely on the first set being inside ( ) as the strings I need. The strings will be numeric characters plus the dash (anything between ( ) would be preferable.) What RegEx pattern would I use?
Here's what I have so far but it gets the first number and not the ones in ( ):
Function Extract_Stuff(ByVal LineText As String) As String
Dim myMatches As MatchCollection
Dim myRegex As New Regex("([0-9]+)")
myMatches = myRegex.Matches(LineText)
For Each successfulMatch As Match In myMatches
Return successfulMatch.Value ' should only be one match, return first
Next
Return ""

Dataadapter, Update, Updatecommand Dataset Stuff?
Jan 25, 2007I'm having trouble updating a sql server database with a dataset using a dataadapter. I have used the dataadapter with success in the past when adding new rows, using a single table, and just calling the dataadapter.update command.However, I am now running into a more complex scenario and I need to use dataadapter.UpdateCommand method and I'm having lots of problems.
The sql statement that I'm using to fill the dataset looks like this: "Select [Order Details].ProductID, [Order Details].UnitPrice, [Order Details].Quantity, [Order Details].Discount, Products.ProductName From [Order Details] INNER JOIN Products ON [Order Details].ProductID = Products.ProductID Where OrderID='" & strOrderID & "'", sqlConn"
This is pulling the data from 2 different tables (Order Details and Products) and then joining them and filling the dataset, and I am seeing the exact results I want. I am then binding the dataset to a datagrid control that allows the user the option to edit the datagrid, which in turn updates the dataset.
So that being said how do I get the updated dataset back into the database? I tried using dataadapter.update but it informed me that I now need to use dataadapter.UpdateCommand. Ok, so I've looked up how to use UpdateCommand but I cannot for the life of me figure out how to set up the right sql command statement. Part of what has me confused is the UpdateCommand examples I have seen are working with a specific row and updating that rows data. I can get that to work but I want all changes to the dataset to persist and update to the database when the user is done working on the datagrid.
Also, the examples shown set up command parameters but again, this is only confusing me because I just want to send the whole dataset back to the database. It seems like the parameters are saying "Ok, this specific row in this specific dataset.table, update these specific fields in this specific database". I'm not sure how to accomplish that when working with a datagrid.
