Hi.
You can not use DataReader for backward reading. You can use disconnected DB.
To use that you can use DataSets and DataAdapters.
Here is a quick and simple tutorial:
http://www.csharp-station.com/Tutorials/AdoDotNet/Lesson05.aspx
The tutorial is in C# but the syntax is similar to VB.NET.
Have fun.

Your question is difficult to understand. You can split your senesce like this
Dim words() As String = Split(TextBox1.Text, " ")
and get each word like this
Textbox2.Text = words(0)<br />
Textbox2.Text = words(1)

If you want code handed to you, a little Google goes a long way...

VB6 doesn't have anything in it that will do this natively, so you have to have some kind of library to di it for you, or implement your own. Using someone elses library would be FAR quicker.

Hi to all,
I created an window explorer application.For the enhancement of features , I want to create the password for the file or folder on right clicking the node.Can somebody send me any link or code.
Thanks

You have to provide more information for someone to be able to help you.
You have described something that uses a password, but not what the password is supposed to be used for. Is it supposed to protect the file or folder, or what? What specifically is it that you need help with? Creating a password? Store a password somewhere? Handle password protection? Handling the event of right clicking?

Hi,
I mean , if the user applies the password on any file or folder then next time the security get maintained for the
later.User should be able to open that file or folder if
correct password is typed .I want that kind of program in vb.net.
If you can send any code or link.
I am in urgent need of it.
Thanks

What you're thinking of has been asked a dozen times before...
You can't do this without a black-belt in writing NTFS Filesystem Extensions. You can't attach a password to a folder. It's just not practical because it's a huge pain to administer. Protecting the contents of a folder is what NTFS permissions is for.
You CAN, however, do something along the lines of how Windows XP handles .ZIP files. You can double-click any .ZIP file and XP/2003 will treat it as though it's a folder. Password protected .ZIP's are, however, not supported. This would require you to write a Shell Extension. Again, not for the faint of heart or weak in COM Interop skills.
Looking at your post history tells me that you're nowhere near understanding Shell and NTFS internals enough to pull either of these things off.

Yes the TSQL is malformed. Lookup the DATEDIFF() and GETDATE() functions in the SQL Books Online (or Google them - it'll be faster).
BTW, is this 'online dating' service you are writing a commercial venture or just something you are playing around with?

Yeah i am building one but not to play around. once the site is fully functional i might deploy it and show them to potential buyers can you please tell me why u asking me? happy to answer honestly.

I'm asking because quite frankly the type and number of questions you are asking about programming indicate that you have little experience doing so.
This in itself is not a problem as we all had to start somewhere, but if you are building an app for commercial use - whether for an employer or for sale to potential customers - you really should be reading up more on the tools you use to construct it. BTW are there not too many 'dating websites' out there already (i.e. what makes your application more attractive to potential clients than those already on the market)?
Many of the questions so far would have quite easily been solved with a brief reading of the relevant parts of said manuals - which are provided with Visual Studio and are freely searchable online.
This is the reason that I have been a bit short in my answers to your questions. I firmly believe that one should exhaust all other avenues for resolution before posting on this board. You are by no means "Robinson Crusoe" and others have also trod this same line. If I, or anyone else, simply posts the answer, you'll never get the experience of researching it for yourself.
My aim is to help people help themselves wrt programming - hence my signature lines.
All the best in your venture.

I am new to using delegates and am getting "Error Binding To Target Method" error on the CreateDelegate line. What am I doing wrong? Thanks in Advance.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sTest As String = "MyTest"
Dim test As ToolStripMenuItem
Dim currentType As Type = Me.GetType
Dim method As MethodInfo
Dim delTest As [Delegate]
method = currentType.GetMethod(sTest)
If Not method Is Nothing Then
MsgBox(method.Name)
delTest = CreateDelegate(GetType(EventHandler), method)
test = New ToolStripMenuItem("Testing", Nothing, delTest)
Else
test = New ToolStripMenuItem("Testing")
End If
MyBase.mnuMain.Items.Add(test)
End Sub
Public Sub MyTest(ByVal sender As Object, ByVal e As EventArgs)
MsgBox("testing")
End Sub
|
|
|
|
|
This isn't working because, for some reason, MyTest's signature doesn't match the signature of EventHandler.
You'll run into another problem after that one's fixed. The method you're binding the delegate to must be a Shared method (Static in C#).
Imports System.Reflection
Imports System.Delegate
.
.
.
Public Shared Sub MyTest(ByVal sender As Object, ByVal e As EventArgs)
MsgBox("Testing...")
End Sub

The amount of questions you are posting on this board show that you really should RTFM a whole lot more.
Simple really - use the SELECT TOP function. You'll find a reference to it in the SQL Books Online (you ahve installed them havn't you)

what is RTFM? i know selecting top rows but i was just confused whether it produces the same effect as it did by mysql.

HOW TO INSERT A THUMBNAIL INTO DATAGRID OF PICTURE FROM A PICTURE BOX IN WINDOWS APPLICATION
VIJAYKUMAR.N.S
|
|
|
|
|
First, STOP YELLING!
Second, you haven't specified anything about your datasource or how you're populating this DataGrid.
You might want to look at this[^] to see if it fits your needs. The code is in C#, but is easily convertible to VB.NET.

This code always results in a file in use error (error 57):
Sub DelPic(ByVal filename As String)<br />
<br />
Dim fi As New FileInfo(filename)<br />
If Not fi.Exists Then Exit Sub<br />
Try<br />
fi.Delete()<br />
Catch ex As Exception<br />
MsgBox(Err.Source & " caused an error of type " & Err.Number)<br />
End Try<br />
<br />
End Sub
No other programs are running, all files are closed and file.attributes shows normal.
What am I doing wrong?
