Hey Bob
How do I put the data into block sizes?
Thanks
|
|
|
|

There is another member of the .net Rijndael class that will put the data into appropriate block sizes, Although I don't recall which member you need offhand.

Hey there vbvic. I've had to do a similar project myself. I was tasked to create a simple program that could lock or unlock a file just by the click of two respective buttons. Being a VB noob, I thought that encrypting would be the right way to go.
Anyone could enlighten me with some sample codes to get started?
Thanks in advance.

Outlook Express doesn't expose a COM OBject model. Only the Office version of Outlook does. If you can't find this library under the COM tab, in References, then you don't have Office's Outlook installed or you haven't installed the .NET Framework programming support option when you installed Office.

You can launch the default mail client simply by starting a new Process and giving it a command line of "mailto:emailaddress@somewhere.com".

i had started a new process but when i pass to it the mailto command it dosen't work , i don't get the new mail message window
objProcess = New System.Diagnostics.Process
objProcess.Start("C:\Program Files\Outlook Express\msimn.exe", "mailto:microuser@gmail.com")

No, no, no... You don't pass in an .EXE. You just give it the "mailto:" line!
objProcess = New Process
objProcess.Start("mailto:microuser@gmail.com")

I am trying to download files in VB 2005 Asynchronously (To avoid UI JAM) , I need to post the filename to the server and the file is being supplied as server response. Pls. guide. This is what I am currrently using but its OK for Text, Html files.
Public Sub PostData(ByVal strURL As String, Optional ByVal POST1 As String = "")
' Declare a variable named client of type WebClient.
Dim myWebClient As WebClient
' Instantiate a WebClient object and assign it to the 'client' variable.
myWebClient = New WebClient
' Add handler to process theWebClient's DownloadProgressChanged events.
AddHandler myWebClient.UploadProgressChanged, AddressOf UploadProgress
' Add handler to process theWebClient's DownloadCompleted event.
AddHandler myWebClient.UploadStringCompleted, AddressOf UploadCompleted
' Declare a variable named downloadUri of type Uri
Dim downloadUri As Uri
' Instantiate a new Uri object and assign it to the 'downloadUri' variable.
downloadUri = New Uri(strURL)
myWebClient.Headers.Add("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4")
'myWebClient.Headers.Add("Accept-Language", "en-us,en;q=0.5")
Try
myWebClient.UploadStringAsync(downloadUri, "filename=" &POST1)
End If
Catch e As System.Net.WebException
MsgBox("A web exception has occured [" & strURL & "]." & vbCrLf & " System returned: " & e.Message, MsgBoxStyle.Exclamation, "Error!")
Exit Try
Catch e As System.Net.ProtocolViolationException
MsgBox("A protocol violation has occured [" & strURL & "]." & vbCrLf & " System returned: " & e.Message, MsgBoxStyle.Exclamation, "Error!")
Exit Try
Catch e As System.Net.Sockets.SocketException
MsgBox("Socket error [" & strURL & "]." & vbCrLf & " System returned: " & e.Message, MsgBoxStyle.Exclamation, "Error!")
Exit Try
Catch e As System.IO.EndOfStreamException
MsgBox("An IO stream exception has occured. System returned: " & e.Message, MsgBoxStyle.Exclamation, "Error!")
Exit Try
End Try
End Sub

What? Nobody, Is that impossible???
|
|
|
|
|
It seems to be a tough one! but Hey! pro's pls. get a workaround.
|

In the simplest design, you'd wrap a WebClient in a class that does nothing but submit a request, then wait for the response. Create a new instance of this class on a seperate thread, giving it the URL of the file you want to download. Any events for tracking progress would have to be marshalled back to the UI thread.
Do I have any example code? Nope. I suggest searching the articles and Googling around for it.

For example, i have a db with name abc.mdb in this db i have a table tha calls "aaa" in this table i have the information "a" "b" "c" "d". Is it possible to save the information of the lines "a" and "b" in a TXT at the same time? Could some one give me an example?

No you will have to save to the db then save to a file or vice versa.

I have created a software in VB.dotnet (Microsoft development enveronment 2002)
After installation i received (KeyCodeV2.dll) Error. As a solution I added (Managed.msm, Database_Access.msm, Database_Access_enu.msm, Regwiz.msm)
Again after creating new setup and installing, now even if I dont receive any ERROR my report is not shown (Loaded).
But same report while running from environment is shown.

When you say "bind the second table to second combobox and the third table to the third combobox"... Are using three different DataAdapters and three different DataSets?
|
|
|
|
|
Yes i did, three adapter, three dataset, three sql command, all of that in one event, form_load event, is it someting to do with the event?
Abbas
|
|
|
|
|
Interesting...
Can you email me the code or post it here and I'll take a look at it?
|
|
|
|
|
I'm sorry, now is ok, i just miss type the objname of each data adapter and dataset, now is ok, but i have another question
I already bind the column from table to combobox, and succesfull, but i need to add an empty row, so when the form run the combobox is empty but when i select it will show the empty row and the fields, the result is like this
'objComboBox1
" " 'empty field
"Field 1" 'come from table
"Field 2" 'come from table
"Field 3" 'come from table
"Field 4" 'come from table
etc
Here are the Code that i use
Dim objConn As New SqlConnection
Dim objDS As New DataSet
Dim objDA As New SqlDataAdapter
Dim objCM As New SqlCommand
objConn.ConnectionString = "<cut>"
Try
objConn.Open()
Catch ex As Exception
MsgBox(ex.Message)
Exit Sub
End Try
objCM = New SqlCommand("Select Name_VC from tPersonnel_TB Order by Name_VC", objConn)
objDA.SelectCommand = objCM
objDA.Fill(objDS, "Personnel")
CBPersonnel.DataSource = objDS.Tables("Personnel")
CBPersonnel.DisplayMember = "Name_VC"
Thnx
