Hi Luc,
Can you please tell me what details you want?
My code is exactly as listed in the article shown above.
The string to encrypt is: encryptitman
The key I use is: 123456789012345678901234
The iv I use is : 12345678
The encryption goes on fine but the code is not able to decrypt the encrypted string.
I supply the encrypted string exactly to the decrypt function.

The article is followed by some discussions, where one of the participants is having the problems you're having, and he came up with a solution for it.
If it still would not work, you'd better post there.

have created function in class file.
Public Shared Function dsCntrctET() As DataSet
Dim sqlCntrct As String = "Select * from CNTRCT_ET where CNTRCT_ID=" & CISCNO
Dim cmdCISContract As New OracleCommand
Dim daCISCntrct As New OracleDataAdapter
Dim dsCISCntrct As New DataSet
Dim cmdCISBuilder As New OracleCommandBuilder
Try
With cmdCISContract
.Transaction = myTransCIS
.CommandText = sqlCntrct
.Connection = cnCIS
End With
daCISCntrct = New OracleDataAdapter(cmdCISContract)
daCISCntrct.FillSchema(dsCISCntrct, SchemaType.Source)
cmdCISBuilder = New OracleCommandBuilder(daCISCntrct)
With daCISCntrct
.TableMappings.Add("Table", "CNTRCT_ET")
.Fill(dsCISCntrct)
.SelectCommand = cmdCISContract
.InsertCommand = cmdCISBuilder.GetInsertCommand
.UpdateCommand = cmdCISBuilder.GetUpdateCommand
.DeleteCommand = cmdCISBuilder.GetDeleteCommand
End With
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return (dsCISCntrct)
End Function
it returns dataset that i can use for getting value from table.
but while saving data, i have to use dataadapter for da.update(ds,"table") and ds.acceptchanges.
this i have to use in multiple forms as this data comes from 3rd party so i dont want to write this in every form . so i thought how to return data adapter and dataset from the same function. as i wanted to use daCISCntrct and dsCISCntrct.

Pass any other objects you want to return in as an out parameter.

By the look of things, you are used to vb6. Welcome to vb.net.
Aside from the fact that you can do a lot of things much easier in vb.net / Visual Studio, the very first thing is error handling.
To find out what the error is, enclose the code in each sub in a try catch clause:
Private Sub FirstButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FirstButton.Click
Try
'your code here
Catch ex as Exception
MsgBox(ex.tostring)
End Try
End Sub
This will tell you what the error is, and exactly on which line it occurs (you can turn on line numbers in Visual Studio to make it easier).
My advice is free, and you may get what you paid for.

Hi Experts,
I have a datagrid in which i want to give validation to each cell of my DataGridView...
such as 1st cell should take only "integer", 2nd "string"..........
Thanks
|
|
|
|
|
I use the CellValidating event of the grid and write my own validation methods. If the cell doesn't pass validation then you can call the CancelEdit() method which will revert the cell's invalid value back to the previous value.

Thanks for reply!!!
I am trying alot but got error for same.....can you please send me sample code for same....
|
|
|
|
|
If you post your code and the error you are getting I'm sure that myself or somebody else will be able to point you in the right direction.
|
|
|
|

Private Sub dgvstock_CellValidating(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvstock.CellValidating
Dim s As String
s = Convert.ToString(dgvstock.CurrentRow.Cells("Description").Value)
Dim a As Integer = s.IndexOfAny("0123456789".ToCharArray())
If a >= 0 Then
MessageBox.Show("Enter only characters")
End If
Here we check for validation for string
|
|
|
|
|
Ah I see. Well the CellValidating event validates the content of cell that has just lost focus (well that's the way I interpret it anyway). Therefore, you have to check which cell is being validated and then do the validation.
So what I do (and this isn't necessarily the best or the only way) is use a select statement to determone which cell is being validated and then do the required validation. Something like:
Select Case dgvstock.Columns(e.ColumnIndex).Name
Case "Description"
-- do your validation for the description column here --
End select
Hope this helps.

You can use DataGridView's CellValidating event for this.

I have this code and I need to add a shortcut key (CTRL+B) for this function
If I Press (CTRL+B) this function should be executed..
How to add it ...? and how to call this function?
Here is the part of the code and I have also attached full source code with it..
Private Sub Brwse_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Brwse_Button.Click
Dim RetVal As Integer
Dim FolderName As String
FolderName = ""
RetVal = FolderBrowserDialog1.ShowDialog()
FolderName = FolderBrowserDialog1.SelectedPath
If Not (Trim(FolderName) = "") Then
LogLib_TxtBox.Text = FolderName
End If
End Sub

you would need to do it at the form level.
+turn keypreview on (property of the form)
+in the keydown_event, add the code to test if the control key is pressed and the b key is pressed via the 'e' argument of the routine
+if so, call brwse_button_click(nothing,nothing)
typically however, you also give the user a "hint" that the hot-key is available via a menu item or someother means. if you use the menu item, then you can assign the hot-key there.

Whoops! Wrong reply button...
|
|

In addition to what nlarson said, move that code you want to call to its own sub instead of putting everything in the button handler. This will allow you to call the code from anywhere in the form without passing in arguments you don't have.

Hi,
I'm new to the programming world, but not the computer world. Anyway, I've just recently downloaded Visual Basic 2008 Express Edition, and so far I love it. However, I came across an old source file that's opensource on SourceForge.net and downloaded it. I was trying to upgrade the Project1.vbp using the VB2k8 Express upgrade wizard when it told me that the upgrade failed because the mdlFormHandling.bas file was missing. The problem is, I went into the folder and looked and it's not missing. It's right there. I took some screenshots to show you if anyone could please, please, please, please help me. I'm just a lowly college kid! No money for the big guns yet! >.<
The Upload Error Screenshot - http://i927.photobucket.com/albums/ad117/teknozwizard/UpgradeError.jpg[^]
File is there Screenshot - http://i927.photobucket.com/albums/ad117/teknozwizard/Fileisthere.jpg[^]
Please help this newb!!!

By the look of it, the studio is looking for the file in a different place. Check the path in the error message, against the path that the bas file is actually in.
You may have to copy the file to the path mentioned in the error message.
My advice is free, and you may get what you paid for.

I've got and tried to track through that filepath and.....nothing. I've done a system wide search and I don't have a file labelled "VB98" to try and find and get into to follow the rest of the path. I'm completely at a loss here. I thought that maybe it was looking for a library I didn't have so I went online and downloaded the libraries for VB2k8EE from microsoft's website and installed them, but unfortunately, I'm still having the same trouble....I can't copy the file's into the location because the location it's looking for them in doesn't seem exist and I'm not even sure what the full filepath would be because it gets cut off with the "\...\...\...\VB98\" and etc...I thank you for your response though.
