I am currently trying to read a file from the Web and save this into my SQL Database but am experiencing difficulty in saving the file. What is getting inserted into the database as the file data seems to be wrong so gives an error on trying to read it back from the database. The following is the code I am using:
Dim objWReq As WebRequest
Dim objWResp As WebResponse
objWReq = HttpWebRequest.Create(CVDocumentURL)
objWResp = objWReq.GetResponse()
Dim objStream As System.IO.Stream
objStream = objWResp.GetResponseStream
Dim objData As Byte() = ReadFully(objStream)
objWResp.Close()
Dim ObjAdapter As New TableAdapters.Method
ObjAdapter.InsertFile(ApplicationId, UserId, VacancyId, DateCreated, CoveringLetter, CVDocumentURL, Nothing, objWResp.ContentType, FileName, objWResp.ContentLength, objData)
On checking the properties of objData they all seem to be fine before doing the insert. Does anyone know what is going wrong here?
Thanks

So I have a report server in a local area network that I want to access via a winform application with a Report viewer
my Report viewer control Name is rpt_ReportViewer
and here's the Code to view reports on the reportviewer rpt_ReportViewer
Private Sub rpt_GenerateReportBtn_Click(sender As Object, e As EventArgs) Handles rpt_GenerateReportBtn.Click
With rpt_ReportViewer
.ServerReport.ReportServerUrl = New Uri("http://SERVER/ReportServer")
.ServerReport.ReportPath = "/Search Assets Table/Search Assets Table"
.RefreshReport()
End With
End Sub
whenever I run this code it generates an exception in the report viewer saying "The Request Failed with HTTP Status 401: Unauthorized."
I don't know whats wrong but I used this very same code on a localhost and it worked http://localhost/reportserver
can anyone help me figuring out whats wrong please ? thanks in advance.
There's the solution
Dim Credential As New NetworkCredential("User name", "Password") 'Was missing this Line
With rpt_ReportViewer
.ServerReport.ReportServerCredentials.NetworkCredentials = Credential 'Was missing this line too
.ServerReport.ReportServerUrl = New Uri("http://SERVER/ReportServer")
.ServerReport.ReportPath = rpt_ReportsListBox.SelectedValue
.RefreshReport()
End With
I am building a data-entry program in vb.net that 5 people will share using, and I have problems setting the right database connection. It would do basic things like: pulling up the stock units, save job, load jobs operations.
The database I'm using is Access database (.mdb). This database will be located in a local server drive (mine is in Z drive) and the connection string looks like this
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="Z:\Jimmy's Files\Quality Enclosures.mdb"
This works fine on my computer, but the problem is it does not work on my coworkers computer.
d (\dc-qenclosures) (Z:) is the loacation to my local server drive, but on my coworker's computer, it is set up as
d (\dc-qenclosures) (Q:).
So, whenever I open the program on my co-worker's computer, it gives me an error saying that the database Provider=Microsoft.Jet.OLEDB.4.0;Data Source="Z:\Jimmy's Files\Quality Enclosures.mdb" does not exist (which makes sense because it is not under Z: on his computer)
I know how to use the OpenFileDialog to browse for mbd files.. but how do I set this as the new database connection?
I want to create a properties menu to set the database location.
This is the code I have so far to browse for the database file
Private Sub RadButton6_Click(sender As Object, e As EventArgs) Handles RadButton6.Click
Dim myStream As Stream = Nothing
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.InitialDirectory = "c:\"
openFileDialog1.Filter = "mdb files (*.mdb)|*.mdb|All files (*.*)|*.*"
openFileDialog1.FilterIndex = 1
openFileDialog1.RestoreDirectory = True
If openFileDialog1.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
Try
myStream = openFileDialog1.OpenFile()
If (myStream IsNot Nothing) Then
myConString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & openFileDialog1.FileName
con.ConnectionString = myConString
con.Open()
End If
Catch Ex As Exception
MessageBox.Show("Cannot read file from disk. Original error: " & Ex.Message)
Finally
' Check this again, since we need to make sure we didn't throw an exception on open.
If (myStream IsNot Nothing) Then
myStream.Close()
End If
End Try
End If
End Sub
I'd second #OneFineDay's suggestion of trying the UNC path first, but to answer your main question of browsing for and saving a database path, you may want to look at storing elements of your connection string in My.Settings, so you could make the path a user-level setting. There's an MSDN article with examples here:
Using My.Settings in Visual Basic 2005
In short, you'd have the code sample you shared save the value to My.Settings.DataPath (or whatever you decide to call the setting). Then when you're connecting to the database and need the connection string, you'd make it read from My.Settings.DataPath.
Of course, that'd store your path to the database in a plain-text app.config file by default, so you'll want to be conscious of that and take appropriate steps if there are any security concerns around your app or database.
I've done alot of research on this and found a number of help sites but still can't understand why this sometimes doesn't work.
I'm trying to access a sharepoint site (to which there are no restrictions for me) and extract all the files in a folder within that site.
Sometimes my Path works and it does it, other times it does not. I have a feeling it works if I've gone into the sharepoint site on my browser before but can't confirm that (because I just tried it again now and it doesnt work ARGGH). But the same code below has worked in the past.
It's failing on the File System Object function below
Public Function GetFullFileName(strfilepath As String, _
strFileNamePartial As String) As String
Dim objFS As Variant
Dim objFolder As Variant
Dim objFile As Variant
Dim intLengthOfPartialName As Integer
Dim strfilenamefull As String
Set objFS = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFS.GetFolder(strfilepath)
'work out how long the partial file name is
intLengthOfPartialName = Len(strFileNamePartial)
For Each objFile In objFolder.Files
'Test to see if the file matches the partial file name
If Left(LCase(Replace(objFile.Name, " ", "")), intLengthOfPartialName) = LCase(strFileNamePartial) Then
'get the full file name
strfilenamefull = objFile.Name
Exit For
Else
End If
Next objFile
'Return the full file name as the function's value
GetFullFileName = strfilenamefull
End Function
I get a "Run-time error '76': Path not found" when it gets to the GetFolder(strfilepath) code
The strfilepath is just a regular sharepoint site name (e.g. like \teams.uk\gm\FX\SharedDocuments\London\11) November 2013\20 November\Reports)
As mentioned I've tried different variations of the file path including DavWWW but nothing seems to work and I dont know what else to try.
Any advice please?
Thanks

The webclient service must be started to Access SharePoint using the FileSystemObject.
This service is often not started when you first log on. However as you access SharePoint via the normal user interface it gets started. I think this is why your code works inconsistently.
If you have admin rights on the local machine you can start the service manually (or using code). However if you don't have rights then you can try a trick - it's clumsy but works.
Using VBA code open a known SharePoint folder in explorer view then close it. This will trigger webclient to start.
I just learned that RavenHQ is an easy-to-use database for .NET and especially Silverlight. I'm trying to insert some Test Data (see Code) but it won’t work. I think I am missing something big because I'm new to RavenDB.
I added the references to the project and created clientaccesspolicy.xml and crossdomain.xml. I get (Firebug) an HTTP 200 Response to "GET clientaccesspolicy.xml" from 1.ravenhq.com but nothing else happens and no data is inserted. Any Ideas would be much appreciated.
Private Sub TestRavenDB()
Try
Dim ds = New DocumentStore()
ds.Url = "https://1.ravenhq.com/databases/AppHarbor_60e82bd1-234f-4178-a59a-b527a1d391bb"
ds.ApiKey = "1f827c44-3e38-4e66-8801-83ba03b01f67"
ds.Initialize()
Dim p As New Person("Donald")
Dim session As IAsyncDocumentSession = ds.OpenAsyncSession()
session.Store(p)
session.SaveChangesAsync()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
Note that you have SaveChangesAsync there. Before your test return, you need to wait for that to complete.
Please see the pic. and advise how I can change this connection string at run time. This is going to be on Client's computer and my application will need to change the name of computer after user enters it.
Thanks!
Just on the top of my head..
Dim adapter As New dbTestSharingDataSet.tblTestTableAdapter
Dim conn As New SqlConnection()
conn.ConnectionString = MyConnectionManager.ConnectionString
adapter.Connection = conn
Dim table As DataTable = adapter.GetData()
