Please note that I am a newbie in WMI, have been researching this issue for most of the day, and even though there are hundres of posts, I am struglling to find any help on this specific problem.
Experiencing an issues using Win32_DiskDrive - Caption and also name functions:
When I execute the VB.script:
Try
Dim connection As New ConnectionOptions
connection.Username = userNameBox.Text
connection.Password = passwordBox.Text
connection.Authority = "ntlmdomain:ms1"
Dim scope As New ManagementScope( _
"\\ms1\root\CIMV2", connection)
scope.Connect()
Dim query As New ObjectQuery( _
"SELECT * FROM Win32_DiskDrive")
Dim searcher As New ManagementObjectSearcher(scope, query)
For Each queryObj As ManagementObject in searcher.Get()
Console.WriteLine("-----------------------------------")
Console.WriteLine("Win32_DiskDrive instance")
Console.WriteLine("-----------------------------------")
Console.WriteLine("Caption: {0}", queryObj("Caption"))
Next
it correctly lists the 5 harddrives that I have in the server i am querying.
But when I execute it in asp.net (vb) it lists only the 1 drive.
Dim query4 As New ObjectQuery("Select * from Win32_DiskDrive")
Dim searcher4 As New ManagementObjectSearcher(scope, query4)
For Each queryObj3 As ManagementObject In searcher4.Get()
'Availability
' text15.Text = queryObj3("Name")
text16.Text = queryObj3("Caption")
Next
My resuls are bountd to a textfield, formatted to wrap and multiline.

It seems you overrwrite text16.Text again and again, so the result in the end would be the information of the last device only.
Try concatenating the string instead:
' TODO: Use proper string formating instead of simpy string concatenating '
text16.Text = text16.Text & queryObj3("Caption")

I have a BMC Remedy database with the AR System driver. I need to read this database, extract the information and save it in TXT.
I've searched in several places and found nothing. I tried to build something with what I was reading, but it is not working very well.
dim sql
dim connectionString
Dim bindingSource1
Dim myAdapter
Dim commandBuilder
connectionString="DRIVER={AR System ODBC Driver};ARServer=10.2.67.22;ARServerPort=1530;UID=xxxxx;PWD=xxxxx;ARAuthentication=;SERVER=NotTheServer"
sql="SELECT ""Controle_Crachá"".""Request ID FROM Controle_Crachá Controle_Crachá"
Me.SQLDS_reportresults.DataSource = bindingSource1
myAdapter= New OdbcDataAdapter(sql, connectionString)
commandBuilder= New OdbcCommandBuilder(myAdapter)
Dim table As New DataTable()
table.Locale = System.Globalization.CultureInfo.InvariantCulture
myAdapter.Fill(table)
bindingSource1.DataSource = table
Me.SQLDS_reportresults.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader)
Currently I'm develop a system using VB.NET. I have the following query for UPDATE. This query is work when I run in SQL Developer
UPDATE CCS2_TBL_INSPECTION_STANDARD SET CCSEQREVITEM = :CCSEQREVITEM,
CCSREVEFFECTIVEDATE = TO_DATE(:CCSREVEFFECTIVEDATE,'DD/MM/YYYY') WHERE
CCSEQID = :CCSEQID
But when I try applied this query in VB.net, its not work. Actually the flow for this update function is work but when I update the data, it is not working. For example, I want update name from 'Ali' to 'Abu', when I click the update button, there popup windows says that "Update success" but the name is not change to 'Abu', it still 'Ali'. There no error when I execute. Anyone know? Below VB.net code:
Protected Sub editInspectionRev(eqid As String)
Dim xSQL As New System.Text.StringBuilder
xSQL.AppendLine("UPDATE CCS2_TBL_INSPECTION_STANDARD")
xSQL.AppendLine("SET")
xSQL.AppendLine("CCSEQREVITEM = :CCSEQREVITEM, CCSREVEFFECTIVEDATE = TO_DATE(:CCSREVEFFECTIVEDATE,'DD/MM/YYYY')")
xSQL.AppendLine("WHERE CCSEQID = :CCSEQID")
Using cn As New OracleConnection(ConString)
cn.Open()
Dim cmd As New OracleCommand(xSQL.ToString, cn)
cmd.Connection = cn
cmd.Parameters.Add(":CCSEQREVITEM", txtRevContent.Text)
cmd.Parameters.Add(":CCSREVEFFECTIVEDATE", txtRevEffDate.Text)
cmd.Parameters.Add(":CCSEQID", eqid)
cmd.ExecuteNonQuery()
cn.Close()
End Using
success3.Visible = True
DisplayRevisionDetails()
End Sub
The problem is that you have executed the transaction but failed to COMMIT it. There is an example of the correct method here, which I will reproduce in part below for posterity
Using connection As New OracleConnection(connectionString)
connection.Open()
Dim command As OracleCommand = connection.CreateCommand()
Dim transaction As OracleTransaction
' Start a local transaction
transaction = connection.BeginTransaction(IsolationLevel.ReadCommitted)
' Assign transaction object for a pending local transaction
command.Transaction = transaction
...
command.ExecuteNonQuery()
transaction.Commit()
Observe that we have begun the transaction, and then committed it after executing.
Here I have a double Directory that is suppose to be carrying information from a database in the form of the object hashHelp. Clearly, this isn't working.
Based on everything I've found on this website and around the web, this error message seems to imply that the object hashHelp isn't being created, but you can clearly see it being created above. I have check Any idea what could be happening?
do until rs.eof
if valid(cart, rs, data) = true then
Dim hashHelp
Set hashHelp = new HashHelper
hashHelp.setCode(rs.Fields("Code"))
hashHelp.setDateTime(rs.Fields("ScanTime"))
Dim entry
entry = DateDiff("d", beginDate, DateValue(rs.Fields("ScanTime")))
hash.Item(rs.Fields("ScanTime")).Item(arr(entry)) = hashHelp
arr(DateDiff("d", beginDate, rs.Fields("ScanTime"))) = arr(DateDiff("d", beginDate, rs.Fields("ScanTime"))) + 1
End If
rs.movenext
loop
rs.close
The line the error happens on is hash.Item(rs.Fields("ScanTime")).Item(arr(entry)) = hashHelp
I've checked all the other variable and they are being created and used just fine.
I want to import data from Oracle database to Excel using VBA. I've tried several options I found in here or in the official manual but none of them seem to work for me - I always get the same unspecified runtime error on line with
rs.Open strSQL1, con
or
Set rs = con.Execute(strSQL1)
depending on which one of these two methods I use obviously. Here is the whole code:
Sub data_distribution()
'Setting up the database connection
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Dim strSQL1, strInput, strCon As String
Set con = New ADODB.Connection
Set rs = New ADODB.Recordset
strCon = "Driver={Microsoft ODBC for Oracle}; " & _
"CONNECTSTRING=(DESCRIPTION=" & _
"(ADDRESS=(PROTOCOL=TCP)" & _
"(HOST=XXX)(PORT=XXX))" & _
"(CONNECT_DATA=(SERVICE_NAME=XXX))); uid=XXX; pwd=XXX;"
'--- Open the above connection string.
con.ConnectionString = strCon
con.Open
'con.Open strCon
'--- Now connection is open and you can use queries to execute them.
'--- It will be open till you close the connection
'Definition of parameter
strInput = InputBox("Insert car_id")
strSQL1 = "select * from car where car_id = " & strInput & ""
'Executing the query
'rs.activeconnection = con
'rs.Open strSQL1, con
Set rs = con.Execute(strSQL1)
rs.Open strSQL1, con
Worksheets("Data").Range("A2").CopyFromRecordset rs
'Closing connection
rs.Close
con.Close
Set con = Nothing
Set rs = Nothing
I was thinking it might be an issue of connecting to the database but if I import/query data manual, it works just fine. For example using this manual
http://blog.mclaughlinsoftware.com/microsoft-excel/how-to-query-oracle-from-excel-2007/
I had to download and configure ODAC for Windows from Oracle site to make it work. I use tsnames.ora to set the path. Wasn't sure if I configured it right but it works so I guess there isn't a problem with the connection in vba either, or is it? (The variables are, of course, set to real values, not "XXX")
The query itself is correct and returns valid results from the database. Libraries necessary to use ADOBD are linked as well. (Microsoft ActiveX Data Objects 2.0 Library)
There is an existing question with the same error but it's unresolved:
Unspecified run time error while executing vba script
I'm guessing it's station/interface specific (I use Excel 2010, SQL developer).
Even though it's been some time I asked the question, here, it's still unresolved so I will answer myself.
The problem was in the car table where one of the attributes was type CLOB (CHARACTER LARGE OBJECT) with lenght over 2000 characters. Excel was unable to cope with that type and the query caused the unspecified error. If I listed all attributes but this one, it all went well.
Good day sirs. I'm trying to retrieve a photo from my access database then load it in a PictureBox but I have this kind of problem which I can't resolve.
I have seen questions similar to mine but I can't understand the solutions given by others as I'm just a newbie. Will someone please help me correct my codes for retrieving image file from access database. Thanks
I'm using access database and Visual Basic 2010.
Here's the code:
Dim arrImage() As Byte
Dim myMS As New IO.MemoryStream
Dim da As New OleDb.OleDbDataAdapter("SELECT *
FROM tblEmp
WHERE EmployeeID= '"
& Me.txtID.Text
& "'", con)
Dim dt As New DataTable
da.Fill(dt)
If dt.Rows.Count > 0 Then
If Not IsDBNull(dt.Rows(0).Item("Picture")) Then
arrImage = dt.Rows(0).Item("Picture")
For Each ar As Byte In arrImage
myMS.WriteByte(ar)
Next
'
inFrm.PictureBox1.Image = Image.FromStream(myMS)
End If
End If
I'm getting a "Parameter is not valid" error from the line
inFrm.PictureBox1.Image = Image.FromStream(myMS)
try replacing the line of code with this
inFrm.PictureBox1.PictureData = myMS.Read
