Top Level SQL Table Row - Save The Top Level Automatically?
Mar 18, 2011
I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

In Visual Basic 2008, there's two different ways that I know of to accomplish the same thing:The Dim on the member level:
Dim counter1 as integer = 0
Dim counter2 as integer = 180
Public Sub SampleSub1()

I have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.

I have procedure (Import) that calls a for a new instance of frmImportData. I also have a class name clsBatch that has a data table property called prpParametersTable.For some reason, I get an error (indicated below with ERROR>>>) when trying to assign prpParameterTable to cv_dtImport2. The error states "Object reference not set to an instance of an object.". Why does this error not happen when I assign dtBP to cv_dtImport1? Both cv_dtImport1 and cv_dtImport2 are equal to Nothing and in my Import procedure dtBP = prpParametersTable.
Public Sub Import(ByVal clsB As clsBatch)
Try
Me.cv_clsB = clsB

Hi Friends,
Hope you all are doing fine.
Brief
I have been into learning VB 2010 Express for around 2 months now; I have been doing it primarily on weekends with a nice book by James Foxall. At the moment I am in Chapter 22 of 24. I have been able to make some sense on what he says but have
been able to follow him well. I plann to read the book in full twice before doing with it at the end of August 2011.
Today's Question
In one of my previous threads 'Becoming a Programmer' @Renee Culver encourages me to try to get to a level deeper. There are many other experienced programmers who have given adivce with equal 'punch' but I like to begin with @Renee Culver's
approach.
James Foxall guides me learning smoothly but I now at the 22nd chapter out of 24 feel a little uneasy. It feels like James tells I do. In Chapter 22 dealing with automation he guides me to work on Excel through VB. The reference to the Server is
set through the VB interface. I like to know how to get to a level deeper on this today. Instead of using the VB interface can't I establish reference purely through VB code? During this weekend I like to try accessing the Google start page
Combo to get search results for 'Novak Djokovic'. Could you help me?
Thank you Friends.

What should go into the top level namespace? For example, if I have MyAPI.WebLogic,MyAPI.Compression, etc. If I put classes into the top level namespace, am I violating the principle of encapsulation?

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.

I was just wondering why there isn't a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are being executed in an application. This feature is a part of log4J. I know I can create a custom level like is talked about here but I don't want to put time and effort in something I feel should be part of the library itself. Do you know about a log4net extension library which implements this or why this wasn't a part of the port to .net ?

Suppose I have some XmlElement; let's call it element. If I want to get all of the child nodes of that element, I can call element.ChildNodes. If I want the text of the element and all its children, then I can go with element.InnerText.

EDIT: Sorry I didn't specify this initially: I'm looking for a solution not involving LINQ (we're in the Dark Ages over here with .NET 2.0).

I have an application that plays wav and mp3 files using the Microsoft.DirectX.AudioVideoPlayback.Audio()function. It works fine, and I can easily set the volume level of the playback... within limits.
That limit is the system volume level. I can set the playback level for the mp3, but if the system volume is muted or set real low it may still play softly.
So how do I set the master volume level, including making sure it isn't muted?

When I use PUBLIC above a Class definition, the compiler gives an error. When I put PUBLIC under the Class definition, I have to qualify the variable with the class name in order to use it in another module.
The documentation says Public can be used at Namespace level. Is there a way to be able to just use the variable name, without any qualifier, across my entire project?
