I am trying to connect to a remote server using a tcpclient and then check if the connection was successful before continuing on with the rest of the program.
i am unsure of how to check if the connection was successful.
|
|
|
|
|
You can do two things:
1) Try to catch exceptions. TcpClient.Connect throws a number of exceptions, among which are SocketException and ObjectDisposedException.
2) Get last error.

i was able to connect to an Excel file using oledb in vb6.0 but there are some unresolved issues
1. rs.Recordcount to retrieve the no of rows in the excel worksheet(i.e 8rows) returns more(6636rows) than the data i have in the excel worksheet.
2. I want to read the header i used so that i can use them as fields in my access db table. but ado start reading the real data instead of starting from the header row.
i am using office-xp. With office xp, reference to Microsoft Office Object library does not allow me to use excel application object in my vb. I want to use this object to open the workbook, get the Worksheet name and read from the worksheet.
any help as regards will be appreciated.
thanks

Hi
I wonder if I can make a table to an existing database without using the
statement "Create Table".
I want to use the Datatable with DataColumns and DataRows I have made. Is
there a way I can connect to the database in code and add this DataTable? If so,
please tell me

I don't believe you can do that. I think you have to create the table with SQL code first.

As far as I know you can't do it that way. You have to create tables using the proper SQL syntax.
From what I remember when talking to a SQL engineer @ MS even the SQL Enterprise manager just talks SQL to the DB engine when creating and deleting tables.

That's part of the SQL specification. The engine and system databases are managed by the same language used to manipulate user databases.

you can add reference to "Microsoft.SqlServer.Smo" and use it's classes to manage (create, alter, drop) any SQLServer objects - tables, procedures, constraints, indexes, foreign keys etc.
Very useful.

That works if your using SQL Server 2005. Other versions, I recommend using the SQL method.
In either case, he wanted to do it just by adding a new DataTabel object to his DataSet, which won.t work at all.

Hi Everybody,
I am trying to upload a new file to a Web Server over a VB.NET App. I am using httpWebResponse and httpWebRequest to do so with a a PUT method. The server returns always a 501 Not Implemented Error. The code works fine on all XP Maschines but not on our Windows 2000 Server. I did have URL Scan installed on the server but killed it because I thought that was the cause of my problems but with no success.
Here is the code:
Dim Response As String = Nothing, FileSize As Double = 0
Try
UploadFile = False
If SourceLocation.ToString.Trim <> "" And DestinationLocation.ToString.Trim <> "" Then
'To set Upload settings
Dim UploadRequest As System.Net.HttpWebRequest = CType(System.Net.WebRequest.Create(New Uri(DestinationLocation.ToString.Trim)), System.Net.HttpWebRequest)
UploadRequest.Credentials = Credential
UploadRequest.Timeout = 60000000
UploadRequest.Method = "PUT"
UploadRequest.ServicePoint.Expect100Continue = False
UploadRequest.ContentLength = New System.IO.FileInfo(SourceLocation.ToString.Trim).Length
FileSize = UploadRequest.ContentLength.ToString.Trim
'To set Upload Stream settings
Dim SourceStream As New System.IO.FileStream(SourceLocation.ToString.Trim, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite)
Dim RequestStream As System.IO.Stream = UploadRequest.GetRequestStream()
Dim Buffer(4095) As Byte
Dim Position As Integer = 0, ivlLoop As Integer = 0, CurLocation As Integer = 0
Position = SourceStream.Read(Buffer, 0, Buffer.Length)
While Position <> 0
RequestStream.Write(Buffer, 0, Position)
Position = SourceStream.Read(Buffer, 0, Buffer.Length)
CurLocation += Position
End While
'To upload Stream on Remote system
Dim WebResponse As System.Net.HttpWebResponse = CType(UploadRequest.GetResponse(), System.Net.HttpWebResponse)
Dim ResponseReader As New System.IO.StreamReader(WebResponse.GetResponseStream())
Response = ResponseReader.ReadToEnd()
UploadFile = True
RequestStream.Close()
UploadRequest = Nothing
SourceStream = Nothing
RequestStream = Nothing
WebResponse = Nothing
ResponseReader = Nothing
ElseIf SourceLocation.ToString.Trim = "" Then
Call MsgBox("Source Location is missing")
ElseIf DestinationLocation.ToString.Trim = "" Then
Call MsgBox("Destination Location is missing")
End If
Catch ex As Exception
Call MsgBox(ex.ToString)
End Try
Thank you in advance,
/Peace2u my friends

Basically, 501 means that the server doesn't support the PUT configuration you gave it. You might want to try reducing that 60000000 millisecond timeout to something like 30000. You might also want to try sending a smaller file, to see where that limit is. Some of these things you can change on the server to support higher limits, but I have no idea where. You might want to ask in the ASP.NET forum for that.

So what's wrong with translating the VB6 code? It's not going to be that different...
