Usually it goes the other way around.
Google for "pdf to html component" and you might come up with something.

I am working in vb.net and it is web application here I want to validate for uppercase or restrict to user to enter lower case in text box. how can I do this.

You can use UCase()...
Eg
Dim stDest as string
stDest = UCase(text1.text)
this will convert content of text box to upper case
Good luck

You can either do it server-side by converting whatever they type in whatever case to the case you need AFTER the page is submitted, or you can write the JavaScript code into the page to handle it on the client-side.
And the is a question for the ASP.NET forum. It really has nothing to do with VB.NET at all.

Can any one please tel me that, can i use MsFlexGrid in VB 2005 express edition and distribute the application legally?
I do not have a VB6 license and Microsoft has stopped distributing any new license for Visual Studio 6
I also want to know the same for common controls and Maskedit boxes

|
|
Why you're using those very old controls is beyond me. Yes, you can still distribute an app with those controls. There are no licensing requirements.

System.InvalidOperationException: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
at System.Data.Common.DbDataAdapter.UpdatedRowStatusErrors(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount)
at System.Data.Common.DbDataAdapter.Update(DataSet dataSet)

You gave the DataAdapter the SQL SELECT to get the records, but you never gave it how to update the database with SQL UPDATE, INSERT, and DELETE statements.
You can have these created automatically by using the OleDbCommandBuilder class.
Dim myDA As New OleDbDataAdpater(myCommand)
Dim cb As new OleDbCommandBuilder(myDA)

Do? OleDbDataAdapter.Update() supports (multiple or INNER JOIN) MS Access Table to be update?? or any other way to update two tables at the same time without making manual hardtype code or such a very long codes?? because in some instance of my application.. I have a DataGridView which its records came from an sql query which are two join table.. The Loading of record works fine.. but when i try to make changes into the DataGridView which also means dataset has also committ changes?? and i try to update the record using:
<b>OleDbDataAdapter.Update()</b>
then an ERROR occur just like this:
<b>System.InvalidOperationException: Dynamic SQL generation is not supported against multiple base tables.
at System.Data.Common.DbDataAdapter.UpdatingRowStatusErrors(RowUpdatingEventArgs rowUpdatedEvent, DataRow dataRow)

at System.Data.Common.DbDataAdapter.Update(DataSet dataSet)
at Employee.frmDTR.UpdateRecord() in C:\Employee\frmDTR.vb:line 136</b>
******************
Heres my Code...
**************************
Private Sub LoadRecord(ByVal strSQL As String)
Try
Me.Cursor = Cursors.WaitCursor
oleConnection.ConnectionString = dbConnectionString
oleConnection.Open()
oleDataAdapter = New OleDbDataAdapter(strSQL, oleConnection)

dbDataSet = New DataSet()
oleDataAdapter.Fill(dbDataSet)
DataGridView1.DataSource = dbDataSet.Tables(0).DefaultView
Me.Cursor = Cursors.Default
Catch ex As Exception
MsgBox(ex.ToString())
Finally
oleConnection.Close()
End Try
End Sub
Public Sub UpdateRecord()
Try
oleConnection.Open()
oleDataAdapter.Update(dbDataSet)
Catch ex As Exception
MsgBox(ex.ToString())
Finally
oleConnection.Close()
End Try
End Sub
***************************

DataAdapters only work with single-table queries. Anything more complicated and you have to supply ALL the SQL statements and objects to update the database yourself.

Hi can anybody help me? I need to retrieve the song play length for mp3 files for my program? I'm not concerned about the other ID3 tag information. Just the mp3 song length(aka individual mp3 file play lengths). please help. thanks
Mr Oizo

Hello Mr Ozio,
I hope the code below helps to retrieve information about MP3 file:
Option Explicit
Public Type MP3Info
Tag As String * 3
Songname As String * 30
Artist As String * 30
Album As String * 30
Year As String * 4
Comment As String * 30
Genre As String * 1
End Type
Function MP3GetInfo(strFileName As String) As MP3Info
Dim sTemp As String, iFreeFile As Integer
On Error GoTo ErrFailed
iFreeFile = FreeFile
Open strFileName For Binary As iFreeFile
With MP3GetInfo
Get #1, FileLen(strFileName) - 127, .Tag
If Not .Tag = "TAG" Then
Debug.Print "No tag for " & strFileName
Else
Get #1, , .Songname
Get #1, , .Artist
Get #1, , .Album
Get #1, , .Year
Get #1, , .Comment
Get #1, , .Genre
End If
End With
Close iFreeFile
Exit Function
ErrFailed:
Debug.Print "Error in MP3GetInfo: " & Err.Description
Close iFreeFile
End Function
Thanks,

Half that code doen't run.I think thats like vb6 or something. Dunno. I'll try change it a bit but I'm really looking to just get the mp3file play time length(song length)? What line or 2 do I use
thanks for the reply
Mr Oizo

Assuming this works at all, it looks to me like it reads id3 tags, which don't include length.

Both managed DirectX and the Windows Media Player can give you this info. MDX might be better, I think it will do it without a control being required on a form.

Hello all. I am in college, my major is CNS. However, we are taking programming I for VB.Net, and either my teacher is awful OR I am just dense when it comes to this stuff. Is there any websites that I can go to get Help via tutorials etc. for this? Any help is appreciated.
Thank you 
Kristi

Search for ‘vb.net’ on Google and you will get enough links for tutorials.
However one which I may suggest you is www.startvbdotnet.com, check other sites also.
