Hi
Is there any method that can be used to return form to state where it was created for the first time( clear all the text box, rebinding all the control, etc ) without closing the form itself?
Thanks and regards,
WiL

No, there isn't. You have to write the code to reset all of this yourself.
Your only other option is to kill the current instance of the form and create a new one.

This will be a solution, if you make your application for you.
Name of the textbox is TextBox1
System.Diagnostics.Process.Start("c:\data\" & TextBox1.text & ".mp3")
You can use it, if Winamp is associated with mp3 files.
If not,
Right click on a mp3 file
Select open with.
Select Winamp from the list
Check Always use the selected program to open this kind of file
Click OK.

You're question doesn't make any sense. Are you asking how to get the currently logged on username?
Environment.UserName will return this as a string.
Dim currentUsername As String = Environment.UserName

For Other applications user should be restricted.

You really can't write anything in code to control this. This type of work is normally done using Group Policies.

Hi I've created my web page using VB.Net. I'm using CuteFTP to upload my web pages. I can upload all other files except .dll files. While uploading .dll files I'm getting this error:
Requested action not taken (e.g., file or directory not found, no access).
Is there any other methods to upload the webpages (VB.Net)
Plz help me.

Upload them to what? A hosting server? You'll have to call the support line for your host to find out what's going on.

VB.Net/MS Access. I need to insert records into a particular table (say X)after getting the data from two different tables (say A & B) and doing some permutations and combinations on it. I am getting entire data from tables A & B into two different Datasets. A loop has been written to parse the records from A (dataset), check in B(dataset) and insert the record in table C. However, this entire process is taking a long time. (i.e: in my test run, to insert around 8 lakh records, it took approx 4 hrs).
As per my perception, the time delay is being caused since I am firing an insert statement directly on the database during every loop cycle. Is there a way to avoid this and speed up the process. (i.e. Can the records be inserted into a dataset and then all the records be directly inserted into the table from the dataset)
Please help me its very urgent !!! Sorry for the long description
With Best Regards,
Mayur

Without seeing any of the relevant code, it's impossible to tell you what's going on.

Sorry once again I am providing a huge chunk of code below. Please review it and provide me with some ideas to speed up the process.
Code :
----------------------------------------------------------------------------
str = "select id, code, name, period from EMP2000"
ipcon.Open()
DA = New OleDbDataAdapter(str, ipcon)
DS = New DataSet
DA.Fill(DS, "irec")
str2 = "select id, code, addr, period from EMPADDR"
DA2 = New OleDbDataAdapter(str2, ipcon)
DS2 = New DataSet
DA2.Fill(DS2, "imsctrl")
DV = New DataView(DS2.Tables("imsctrl"))
str3 = "select Id, code, name, addr from EMPDATA where period = '2000'"
DA3 = New OleDbDataAdapter(str3, ipcon)
DS3 = New DataSet
DA3.Fill(DS3, "emp")
Dim cb As New OleDbCommandBuilder(DA3)
Dim cnt As Integer
cnt = 0
'''
Dim DataRow As DataRow
For Each myrow In DS.Tables("irec").Rows
If (myrow(1).Equals(System.DBNull.Value)) Then
code1 = ""
Else
code1 = myrow(1)
End If
If (myrow(3).Equals(System.DBNull.Value)) Then
period1 = ""
Else
period1 = myrow(3)
End If
If (myrow(2).Equals(System.DBNull.Value)) Then
name1 = ""
Else
name1 = myrow(2)
End If
For Each DataRow In DV.Table.Rows
If Trim(DataRow(1)) = Trim(code1) And Trim(DataRow(3)) = Trim(period1) Then
addr1 = Trim(DataRow(2))
Exit For
End If
Next
dsNewRow = DS3.Tables("emp").NewRow
dsNewRow.Item("code") = Trim(code1)
dsNewRow.Item("name") = trim(name1)
dsNewRow.Item("addr") = Trim(addr1)
DS3.Tables("emp").Rows.Add(dsNewRow)
DA3.Update(DS3, "emp")
Next
----------------------------------------------------------------------------
Dave, Is there a way to insert all the records in a dataset and finally update the dataset to the database? If there is such a way then is it really fast. Thnx for your help.
With Best Regards,
Mayur

Convert these to parameterized stored procedures.
Only grab the data you need at the time.
It looks like you're retrieving every employee in the table EMP2000, then going to another table and grabbing all of their addresses, then your grabbing more name and addresses according to some WHERE statement. WHY????
Do you really need all this information at any one point in your code??? I doubt it! You could retrieve all the RELEVANT stuff in one SELECT statement! But, only get what you need at the time. If you updating someones name, you don't need to retrieve the entire database!
The only thing slowing your code down is your own logic.
