I don't why he put blue line under MemoryStream(bytes)
Dim bytes As Byte() = Table5DataGridView.Rows(0).Cells(3).Value
Using ms As New MemoryStream(bytes)
Dim img As Bitmap = CType(Image.FromStream(ms), Bitmap)
PictureBox1.Image = img
End Using
on error list show me MemoryStream(bytes)is not
defined

Prefix it with the correct namespace, like this;
Using ms As New System.IO.MemoryStream(bytes)
..or Import the namespace

My Windows forms application sends and receives SOAP messages from/to an https server. Messages with simple and complex results work fine. Still one request that I issue and I don't know how to handle its response.
The response that I don't know to to use - in order to download a document - is as follows:
//*
="1.0"="UTF-8"
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:DownloadResponse xmlns:ns1="urn:URNNAME">
<return href="cid:325410.3217896541231.east-soap.sectown.madrid.co" />
</ns1:DownloadResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
*//
Its clear that the document to download is referred to as
<return href="cid:325410.3217896541231.east-soap.sectown.madrid.co" />
But I don't know how should I handle that CID: (Content-id)
Below is the code that sends the request and receives the response:
Private Function SendRequest(ByVal EnvelopContents As String, ByVal ServiceName As String, ByVal FullPathURL As String) As Boolean
Dim myWebRequest As HttpWebRequest = HttpWebRequest.Create(FullPathURL)
Dim encoding As New ASCIIEncoding()
Dim byte1 As Byte() = encoding.GetBytes(EnvelopContents)
With myWebRequest
.Method = "POST"
.ContentType = "text/xml"
.ContentLength = EnvelopContents.Length
.Headers.Add("Accept-Encoding", "gzip,deflate")
Dim Certificato As X509Certificate = SelCert()
.PreAuthenticate = True
....
....
....
End With
Try
Dim newStream As Stream = myWebRequest.GetRequestStream()
newStream.Write(byte1, 0, byte1.Length)
newStream.Close()
Using myWebResponse As WebResponse = myWebRequest.GetResponse()
Dim dataStream As Stream = myWebResponse.GetResponseStream()
Dim reader As New StreamReader(dataStream)
Dim responseFromServer As String = reader.ReadToEnd()
Return True
End Using
Catch ex As WebException
End Try
End Function

Hey everyone, I'm new to this forum. I'm hoping someone can help me understand how to update a table created in visual studio from an unbound datagrid control in a form. The data in the grid control is populated from a text file I import and want to save to the table. Below is the code I'm using. Any thoughts? 
[code]
If IsDBNull(Me.FileData.Text) Or Len(Me.FileData.Text) < 1 Then
MsgBox("You must select the reformatter flate file", MsgBoxStyle.Information)
Exit Sub
Else
Using MyReader As New _
Microsoft.VisualBasic.FileIO.TextFieldParser(Me.FileData.Text)
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Dim currentRow As String()
While Not MyReader.EndOfData
FlatFileImportDataGridView.DataSource = Nothing
Try
currentRow = MyReader.ReadFields()
FlatFileImportDataGridView.Rows.Add(currentRow)
Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
MsgBox("Line " & ex.Message & _
"is not valid and will be skipped.")
End Try
End While
End Using
'FlatFileImportDataGridView.DataSource = FlatFileImportBindingSource
Dim dr As New System.Windows.Forms.DataGridViewRow
For Each dr In Me.FlatFileImportDataGridView.SelectedRows
'Me.DataGridView2.Rows.Add(dr.Cells(0).Value, dr.Cells(1).Value, dr.Cells(2).Value, dr.Cells(3).Value, dr.Cells(4).Value, dr.Cells(5).Value, dr.Cells(6).Value, dr.Cells(7).Value)
Next
For Each row1 As DataGridViewRow In FlatFileImportDataGridView.Rows
Dim copyrow As DataRow = Me.Database1DataSet.FlatFileImport.NewRow
For Each col As DataGridViewCell In row1.Cells
copyrow(col.Value) = (col.Value)
Next
Me.Database1DataSet.FlatFileImport.Rows.Add(copyrow)
Next
Me.FlatFileImportTableAdapter.Update(Me.Database1DataSet.FlatFileImport)
End If
[/code]

Yup. Import the old-fashioned way (generate insert-commands) or spend quite some time on MSDN reading on how to update using the adapters.

Thanks Eddie. Straight to the point. Could you help me a bit more. You mention generating insert-commands. Can you give an example of how I would do this using my example? I'm still trying to make sense of things.

Hey everyone, I'm taking a different approach. Below is the code I'm using to save data from an unbound datagridview to a table using VB. The unbound datagridview control is called "DataGridView1". The bound datagridview control is called "MyImporterDataGridView". This grid is bound to a table called "MyImporter". Everything seems to work. When I click the button it imports a text file into the unbound datagridview control called "DataGridView1 and then the second datagridview control called MyImporterDataGridView which is bound to the table is filled with the data from the unbound grid which suggest to me that the table is being filled with the data. Problem is when I close the form and go to the table to view the data it's empty. What am I doing wrong here?
If IsDBNull(Me.FileData.Text) Or Len(Me.FileData.Text) < 1 Then
MsgBox("You must select the reformatter flate file", MsgBoxStyle.Information)
Exit Sub
Else
Using MyReader As New _
Microsoft.VisualBasic.FileIO.TextFieldParser(Me.FileData.Text)
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Dim currentRow As String()
While Not MyReader.EndOfData
Try
currentRow = MyReader.ReadFields()
DataGridView1.Rows.Add(currentRow)
Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException
MsgBox("Line " & ex.Message & _
"is not valid and will be skipped.")
End Try
End While
End Using
'FlatFileImportDataGridView.DataSource = FlatFileImportBindingSource
Dim dr As New System.Windows.Forms.DataGridViewRow
'For Each dr In Me.FlatFileImportDataGridView.SelectedRows
'Me.DataGridView2.Rows.Add(dr.Cells(0).Value, dr.Cells(1).Value, dr.Cells(2).Value, dr.Cells(3).Value, dr.Cells(4).Value, dr.Cells(5).Value, dr.Cells(6).Value, dr.Cells(7).Value)
'Next
Dim workrow As DataRow
Dim i As Integer
For i = 0 To DataGridView1.Rows.Count - 2
workrow = Database1DataSet.Tables("MyImporter").NewRow()
workrow(0) = DataGridView1.Rows(i).Cells(0).Value 'if the table field is a string
workrow(1) = Val(DataGridView1.Rows(i).Cells(1).Value) 'if the table field is a number
'workrow(2) = Val(DataGridView1.Rows(i).Cells(2).Value) 'if the table field is a number
'workrow(3) = Val(DataGridView1.Rows(i).Cells(3).Value) 'if the table field is a number
'workrow(4) = Val(DataGridView1.Rows(i).Cells(4).Value) 'if the table field is a number
Database1DataSet.Tables("MyImporter").Rows.Add(workrow)
Next
TableAdapterManager.UpdateAll(Database1DataSet)

Hello,
I appreciate a litle help, i'm a newbiie in programing and i'm developing my skills around VBasic 2010.
I'm tryng to develop a chat to work in a network, without server.
The users login to a central database sql, in there i have de records of host and trhu that
-I easely get de Ip,
-in database i can know who is login,
-i can add to database aswell a record of port.
My problem's, without a server, a client need more than 2 port's to connect to for ex. 10 computers (outher clients) or need 20 port's
2 ports to comunicate with any computer?
I appreciate your wise opinion.
best regards,
BGUALTER

Yep. You talk on one and listen on the other. So, what's the problem?

Your "problem" is discovering the other computers.
Stop thinking in an always-connected fashion. If you have 20 IP-addresses, then you can connect to them one atta-time, post your message and disconnect again. Call it broadcasting. No, connecting and disconnecting doesn't take much time.

Forget central sql database. MS allows only up to 10 clients connected to a server/database for free. If you have more than 10 clients connected you will have to buy a sql server license...other ways it will not work .
 If you have all your clients on the same physical locally network you better use udp multicast clients.
You can connect all clients together by one single multicast IP address and one port number (Rx/Tx).
Some years ago i wrote a small udp client test application that can connect up to 255 clients. With this you can send text messages (chat) to one single client or to all connected clients. In a text box the received messages are listed...
Each multicast client gets his individual PC number by using last digits NNN of its own IP Address XXX.XXX.XXX.NNN and the user name will be set by name of the computer.
If you are interested i could help you with the source code  .
Regards Markus

Is this possible to create an event calendar using Visual Basic.net?

Yes. Now do you have a more specific question?
Binding 100,000 items to a list box can be just silly regardless of what pattern you are following. Jeremy Likness

Why is it every noob thinks the language choice severely limits the applications you can write with it??
|
|
|
|
|
it's because they don't really understand what a programming language is...
I'm brazilian and english (well, human languages in general) aren't my best skill, so, sorry by my english. (if you want we can speak in C# or VB.Net =p)

I have a string:
...point_units="meters">...
and I want to extract the word 'meters' (no quotes). How do I remove the quotes?
This is what I **want** to do:
strUnits = Replace(strUnits, "point_units="","")
strUnits = Replace(strUnits, ">"", "")
The extra quote is killing my syntax. Is there a work around?
This is a VBScript that I'm working on but it seems like it should be similar to VB.
