I am new to ADO.Net and I mistakenly using the dataset as how we use recordsets in ADO., I know that it is possible to create a Datatable which will only reside in the memory and hold data. What I need to create is like this.
1. Create Datatable.
2. Fill it with sample data at least 3 lines.
3. Transfer the data from datatable to database (access,sqlsrvr etc).

I'm trying to use a combo box to change the image in a picture box to one that's stored in an external folder. The plan is to, in code, take the part of the file's location that will be constant and concatenate the file name to the end. The file name is stored in a database.

I am reading dates from a table in a database to display in a DataGridView column that is formatted as a date. The problem is that when the value is null in the database my program errors out because it cant convert the value to a date. How do you guys handle this? *Edit: If I set the value of my date variable to "Nothing" it displays as "1/1/0001" in my DataGridView, and I would like the cell to be empty for the null dates.

I am currently using VB. I want to do a Calendar Control which have dates highlighted/selected. All these dates are retrieved from a database.
how to put all the dates into an array Second thing I need to know is how to highlight all the dates in the array.
I have done some research on the internet and they said something about selectedDates and selectedDates collection and dayrender. But frankly speaking, I can't really find any VB codes regarding this. Dates format will be in dd/MM/yyyy

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

How to update the dates into the database server for each company for their jobs to be performed.So if my Admin wants to know all the jobs in this current week. I should be able to pick only those companies and their jobs in this week only.

Say the user specifies these two dates....
Start Date: 2010-12-05
End Date: 2011-01-15
If I select December 2010 I should get the folllowing
startdate = 2010-12-05
enddate = 2010-12-31
Select January 2011 then
startdate = 2011-01-01
enddate = 2011-01-15
Should I subtract dates? How can I get the start and enddate for the current month/year based on the overall start and end date.I'm coding in vb.net.

I'm using two datetimepicker controls to set the start and end dates for a range of dates I'm searching for.I want to make sure that the start date selected is not greater than the end date. This code works, but it runs the messagebox prompt twice for some reason. I've tried to ignore it from doing this, but it's not working. Can someone tell me what's wrong?

In an attempt to find more or less understandable tutorial I have spent the last 2 days googling and reading, and still couldn't find the answer to my question. So that I decided to ask here:I am intermediate in VBA. I have been programming the tool in Excel, that takes some data from Oracle DB and manages it, stores in tables, shows in forms, creates new SQL-Queries, extracts further data from DB etc.
Couple of days ago it was decided that this tool should be a separate executable multi-user application (cause it actually doesn't have to do anything with Excel). Being still a student, I have downloaded the Visual Studio 2010 for free, bought couple of books and that was it... being stuck at the beginning..My problem is: I have absolutely no idea where to start from. I could have started drawing forms with controls, but I am concerned this ain't a right way. What about the GUI? What about the functionality scatch? What shall I start from, having code in VBA?

I'm currently working with a project where I need to transfer the internal audio (sound from the computer) to another computer and play it back there.
I thought of transferring the audio with a TCP server-client connection since I already have the knowledge of how to do that.
My problem now is that I don't know how I would capture the internal audio and how to be able to play it back as a stream on the target computer. I have searched a bit and many people recommend using MCI but I'm not sure if this will work on an "almost realtime audio stream" connection.
So my question is: What is the best way to grab the audio from the computer and then play back the data on another computer (as a stream)? I want to do it in realtime and not "recording" the sound and then send it to the target computer.
