Differences In LINQ Syntax Between .Net And C#?
Jun 29, 2011After I have programmed several projects in VB.Net I to my surprise discovered that there are some more than subtle differences between C# and VB.NET LINQ usage.For example, if we want to group elements by multiple properties (columns) we need to create a new anonymous type explicitly:
var procs = from c in Process.GetProcesses()
group c by new {c.BasePriority, c.Id} into d
select d;
whereas in VB.NET more straightforward syntax will already do:
Dim b = From c In Process.GetProcesses()
Group c By c.BasePriority, c.Id Into Group
Select Group
So, one does not need to create a type with "new" here. What are the other differences? good comparison between the LINQ syntax in C# and VB.NET?
VS 2008 .net And Sql 2005 Syntax?
Feb 12, 2010I am using vb.net 2008 and sql 2005. I am writing a program to translate data from one database to another. Basically I have two dataGridViews, the original data is automatically populated to the first and on clicking the "Translate" button the second dataGridView is filled with the translated information. I am having trouble with the syntax of passing a value from the original dataGridView to SQL and returning the 'id' of the translated data table. For instance, the original has colors stored as "Blue" "Green" etc The new tables now have unique ID's with the color name as attributes. I need to basically be able to pass dgvOriginal.rows(i).cells("color").value to a stored procedure and get the "id" field of that color. Here is what I have so far.

VS 2005 Datatable Differences Between Databases
Dec 2, 2010I probably shouldn't go down these roads, but stuff like this just gets to bugging me. Of course, with any of three possible database backends I should expect some quirks.I have a table that has one primary key field and several NOT NULL fields.So I do a SELECT * from the table and populate a .net datatable with the results.I can create a new row for the table, add the value for the primary key field, and then add the new row to the datatable. Everything works fine in Access.But in Oracle the situation is different.I have to supply values for all the NOT NULL fields before I can add the row to the datatable. As far as I can tell the two tables are the same in the two databases in both databases there is one PK field and the same fields are defined as NOT NULL. So why does the .net data provider for Oracle care when I try to add a row that does not have values in a NOT NULL field and the Access provider not?
View 5 RepliesCOM Object Handling Differences Between 2008 Express And VB 2008?
Jul 15, 2009I recently created a very simple project in VB express 2008 to interface with a COM object from an external vendor. I then downloaded the VS2008 90 day trial and found that the identical code in a VS2008 project results in a COMException error "Object is out of scope". Is anyone aware of any differences in how the two packages handle COM object interfaces as I have run out of ideas. Both projects have identical code and all the references are the same. The CreateObject() method correctly creates the object, but any attempt to access methods inside the COM object result in that error. I can even open the VB 2008 Express project inside VS and it still generates the same error.
Here is the code - the vendor dll in question is from Siebel v8.0.0, you'll notice that I have commented out most of the code that comes after the error. Creating a watch in the debugger on the siebApp variable sees it correctly created as {System.__ComObject}type SiebelHTMLApplication. I first tried this by creating the Property Service for variable siebSvcs, but after I started experiencing the COMExceptions, I reverted to using the most basic method inside the COM object I was creating.

VS 2008 Syntax Clarification If Not (x And Y) =?
Sep 9, 2009I would need some clarification on a syntax : could someone tell me why some people in their code use the following :
If Not (xxx And yyy) = 0 Then
'code

instead of
If xxx = true Then
'code

As an exemple : In a code I use for a listview Item Ownerdraw, it sure works like this :
If Not (e.State And ListViewItemStates.Selected) = 0 Then
' draw the listview item code
End If
but not like this :
If e.State = ListViewItemStates.Selected Then
