If you copy your SQL query and run it in a Query Window (such as SQL Server Query Analyser) does it return data? If your report works fine when you get data from a single table, I would suggest that there's something wrong with your query and/or table links when using multiple tables.

hi,
Make a query/View(which contains record from multiple table) in database which is same to the query which is you supplied at run time.Now create a dataset from Data source configuration Wizard and select this Query/View and then design the crystal report according to this query/view(by setting the database expert to dataset which you created from Data source configuration Wizard)
hope this helps

Hi,
Here is the procedure for saving the image to the DataBase using SQL Server:
1. Get the content length of the image that is to be uploaded
2. Create a byte[] to store the image
3. Read the input stream of the posted file
4. Create a connection object
5. Open the connection object
6. Create a command object
7. Add parameters to the command object
8. Execute the sql command using the ExecuteNonQuery method of the command object
9. Close the connection object.
You may refer to this[^] article for more information on this.
Hope this helps.

In XL, if you hide a sheet (or sheets) in a workbook, it means the USER cannot see them, but does it mean the macros and Forms can't see them as well?
I am running a purchase order system, and want the data tables to be unseen by other users, they access only the PO itself and the Index List, but as soon as I hide the sheets, BANG, lots of crashes!
I don't know what to do, except leave the sheets visible.
Any suggestions?

The sheets are all available to your macro... check that you are not referencing ActiveSheet - substitute with Sheets("SheetName").

I got a vb service that does not want to do IO. It works fine in my test environment but when I deploy it, it doesn't seem to want to do the IO part of its task. Does anybody know why?

This may seem a little obvious, but without the code in front of me, well...
Are you declaring System.IO within the code?
I ask only because I was caught out on this before!

Sorry never thought about the code...
The answer is yes and here is some code to go with it.
Dim sw As New System.IO.StreamWriter(ConfigurationManager.AppSettings("IPAccountingLocation") & routerIP & ".txt")
Try
sw.Write(result)
Catch ex As Exception
Finally
sw.Close()
sw.Dispose()
End Try
Try
Dim path As String
path = ConfigurationManager.AppSettings("AppServer")
Dim CurrentDate = DateTime.Now
path = path + "\" + CurrentDate.year.ToString
Dim DateStr = ""
If CurrentDate.Month.ToString = "1" Then
DateStr = "Jan"
End If
If CurrentDate.Month.ToString = "2" Then
DateStr = "Feb"
End If
If CurrentDate.Month.ToString = "3" Then
DateStr = "Mrt"
End If
If CurrentDate.Month.ToString = "4" Then
DateStr = "Apr"
End If
If CurrentDate.Month.ToString = "5" Then
DateStr = "May"
End If
If CurrentDate.Month.ToString = "6" Then
DateStr = "Jun"
End If
If CurrentDate.Month.ToString = "7" Then
DateStr = "Jul"
End If
If CurrentDate.Month.ToString = "8" Then
DateStr = "Aug"
End If
If CurrentDate.Month.ToString = "9" Then
DateStr = "Sep"
End If
If CurrentDate.Month.ToString = "10" Then
DateStr = "Oct"
End If
If CurrentDate.Month.ToString = "11" Then
DateStr = "Nov"
End If
If CurrentDate.Month.ToString = "12" Then
DateStr = "Dec"
End If
path = path + "\" + DateStr
Dim strRouterName As String = ""
' Just to get the router name
Dim con As New SqlClient.SqlConnection(ConfigurationManager.AppSettings("SQLConn"))
con.Open()
Dim selectName As New SqlClient.SqlCommand("Select RouterName from tblRouters where RouterIP=@RouterIP;", con)
Dim sqlParam As New SqlClient.SqlParameter("@RouterIP", SqlDbType.NVarChar)
sqlParam.Value = routerIP
selectName.Parameters.Add(sqlParam)
Dim sqlReader As SqlClient.SqlDataReader
sqlReader = selectName.ExecuteReader
If sqlReader.Read Then
strRouterName = sqlReader("RouterName")
End If
sqlReader.Close()
con.Close()
path = path + "\" + routerIP + "-" + strRouterName
path = path + "\" + CurrentDate.Day.ToString
Dim dir As New System.IO.DirectoryInfo(path)
dir.Create()
path = path + "\" + routerIP + "-" + CurrentDate.Hour.ToString + "-" + CurrentDate.Minute.ToString + ".txt"
Dim sw1 As New System.IO.StreamWriter(path)
sw1.Write(result)
sw1.Close()
sw1.Dispose()

I have read through twice, and can't see why the io isn't working.
The paths seem clear enough (A little convoluted but readable), and the io definately declared correctly.
What appears to be the problem when running? is it just not opening the streams?

One quick solution...
Check all the Read/Write/Execute all permissions are applicable for creation/modification/deletion of Folder/File on the server that you are trying to connect to!!!

It's running on the server a a local service and is doing io to the local drives. What settings must I check? I'm not connecting to a server with this.

I am trying to populate a table in a strongly typed dataset used for the ReportViewer.
I want to read in an XML file which was created manually using ds.WriteXML.
The strongly typed dataset has been created to match the structure of the XML file written with ds.WriteXML.
How do I read in the XML file, and populate the table within the dataset used for the ReportViewer?
