I have books, and I do use them. I have ordered more books, and will use them when they arrive.

Simply telling me to read a book in no way helps me with this specific issue. I just want to know how to export as, with quicktime in vb.net, and how to query quicktime to report back with its list of export types.

I am not asking someone else to write my entire program for me as others here do, I simply need help in one spot. Telling me to read a book (that has nothing to do with quicktime) is about as useful as not even replying to my message.

I appreciate that I am a n00b, and that I have a LOT more to learn, but I feel as if his reply was simply a blow off.

Maybe i'm just in a bad mood today. maybe not.

The answer to your first question was that basic and fundamental. That's why you got that answer.

That is functionality specific to the QuickTime library. This is a question better asked in a forum specific to QuickTime development, not CodeProject. The odds of someone who has used that library seeing your post are very, very low. If you want an answer that specific, you're going to have to find a forum dedicated to QuickTime. Your question has nothing to do with VB.NET itself.

If you think this answer is a blowoff, I'll just keep my mouth shut and watch as your question goes unanswered, day after day after day. I believe is using the right tool for the job. If you believe walking into a Chevy dealership is the best place to ask questions about a BMW motorcycle, go ahead and wait for answer...

Hello every one

I am new in vb.net and i am working on my assignment about add customer's data in to text file so i have used data writer to write data in to file now i want to add customer's name in to combo box so i have used data reader it's working but i dont want all the customer's details i just want customer's name in combo box

this is the code for write data

'create stream writer to add data in to text tile<br />
    Private Sub AddDataInFile()<br />
        Dim DataWriter As New System.IO.StreamWriter(MyFile, True)<br />
        'get data to variable<br />
        Title = Trim(cboTitle.SelectedItem.ToString)<br />
        FName = Trim(txtName.Text)<br />
        MName = Trim(txtMName.Text)<br />
        SName = Trim(txtSurname.Text)<br />
        Age = Trim(txtAge.Text)<br />
        'write data to file<br />
        DataWriter.WriteLine(Title + FName + MName + SName + Age)<br />
        DataWriter.Close()<br />
    End Sub

and this is for read data from text file

Private Sub AddDataInCombo()<br />
        'get all the name in combo box<br />
        Dim TempData As String<br />
        cboMyList.Items.Clear()<br />
        If System.IO.File.Exists(MyFile) = True Then<br />
            Dim DataReader As New System.IO.StreamReader(MyFile)<br />
            Do While DataReader.Peek <> -1<br />
                TempData = Trim(DataReader.ReadLine())<br />
                cboMyList.Items.Add(TempData)<br />
            Loop<br />
            DataReader.Close()<br />
        End If<br />
    End Sub

i dont want to display age in to combo box just name only, I want to use this name for search so next thing is how to search from name ???? Confused | :confused:

This leaves you with one line, and no way to tell which bit is which. Write a line for each item of data, then you can read them a line at a time and know what each part of the data is.

which symmetric algothrim is efficient to encrypt the MPEG file in dotnet envirnment and through which technique reduce MPEG file in dotnet. plz mention specific algothrim and technique for MPEG file.

Re: MPEG encryption

How many records afected by this code

DotNet is irrelevant, obviously. How do you want to encrypt it, so no-one can play it ?

MPEG is a known format, unless you lower image quality, I don't see how you can make files smaller. It's not like AVI, where AVI itself is uncompressed and the file extension is used by a ton of different codecs that all compress differently

Hi,

Are you talking about VisualStyleElement.Tab.Pane Class?

If yes then please note that this class provides a VisualStyleElement for the border of a tab control page. This class cannot be inherited.

For further details on this issue you may visit the following link:

i have a Procedure that return a row affected. its like this

Create Proc CheckExistance(@username varchar(50))
as
Select @@Rowcount from Login where Username = @username

And on my vb code its like this

Answer = cmd.ExecuteNonQuery()

PLease note that Answer is an integer variable, that i want to assign the value returned by a stored Procedure.

Forgive me about formatting issues, i have a problem with code project lately, buttons don't appear nicely, i cant even use pre, because it takes me to another page.

This doesn't look right. Getting the rowcount from a query in T-SQL requires a separate query.

IMHO, the most efficient way to check for the existence of a record is to use the EXISTS keyword. This is because SQL Server will stop searching as soon as it finds the first match. For instance:

IF EXISTS (SELECT TOP 1 * FROM Login WHERE Username = @username)
  RETURN 1
ELSE
  RETURN 0
END

BTW, not sure what problem you are having with <pre> tags. They're working OK for me.

Hope this helps.

You need to the post a code snippet of what is throwing this error. Without seeing it, anyone who gives you an answer is just guessing at the problem.

He must be expecting someone to know the error code right off the top of their head? Unsure | :~

I just take the whole error code and put it in a google search.
