I Have Problem About this count Keyword after that appear that stuff
Here Code
Public Sub searchayumiKn()
Dim myKeyWords() As String = TChat.Text.Split(" "c)
Dim mySQLQuery As String = "SELECT AIRes FROM T_GKnowledge WHERE "
Dim KeyWordCount As Integer
For KeyWordCount = 0 To myKeyWords.Length - 1
Dim strKeyParameter As String = String.Format("#Param{0}", KeyWordCount)
Dim strWhereClause As String
If KeyWordCount = 0 Then
strWhereClause = String.Format("Keyword LIKE {0}", strKeyParameter)
Else
strWhereClause = String.Format(" OR Keyword LIKE {0}", strKeyParameter)
End If
mySQLQuery &= strWhereClause
cmdhikari.Parameters.AddWithValue(strKeyParameter, String.Format("{0}{1}{0}", "%", myKeyWords(KeyWordCount)))
Next
With cmdhikari
.CommandText = mySQLQuery
.Connection = conayumi
End With
Try
dthikari = New DataTable
dahikari.Fill(dthikari)
answers.DataBindings.Add("text", dthikari, "AIRes", True)
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Critical, "Caution")
End Try
KeyWordCount = 0
TChat.Clear()
Return
End Sub
Got Error #param bla". can anyone delete this count?
i just need original of data record. Not Count every time. just not using count. so freely record
move out from for this declaration
Dim strKeyParameter As String = String.Format("#Param{0}", KeyWordCount)
Dim strWhereClause As String
it's make duplicate declaration the same parameter
hopefully could be useful

I have the following Function intended to identify the username of the user who started a specific process:
Private Function GetProcessAssociatedUserID(ByVal processName As String) As String
Dim user(1) As String
Try
Dim query As New SelectQuery(processName)
Dim searcher As New System.Management.ManagementObjectSearcher(query)
For Each process As ManagementObject In searcher.Get()
process.InvokeMethod("GetOwner", CType(user, Object()))
Next
Catch ex As Exception
End Try
Return user(0)
End Function
However somewhere in the ForEach initiation i'm getting this "ManagementException was Caught: Invalid class" exception thrown into my catch block. I've been in through debug but still cant work out what is. Any help would be much appreciated.
You can try it accomplishing this way
Private Function GetProcessAssociatedUserID(ByVal processName As String) As String
Dim query = "Select * from Win32_Process Where Name = """ + processName + """"
Dim searcher = New ManagementObjectSearcher(query)
Dim processList = searcher.Get()
For Each mObj As ManagementObject In processList
Dim argList As String() = {String.Empty, String.Empty}
Dim returnVal = Convert.ToInt32(mObj.InvokeMethod("GetOwner", argList))
If returnVal = 0 Then
Return argList(1) + "\\" + argList(0)
End If
Next
Return ""
End Function
This snippet works with .NET Framework 3.5 and above. For more details you may refer using-managementobjectsearcher-in-systemmanagement-is-getting-compiling-errors
I need to write 50 million records with 72 columns into text file, the file size is growing as 9.7gb .
I need to check each and every column length need to format as according to the length as defined in XML file.

I've been trying to create a function that returns an object of type. This function below is currently inside my dataclass and can be called from any object that inherits the dataclass. My problem is when I try and return my object. It populates just fine while I am inside the function. When I get back out to the calling object its all empty like it's a new object.
Here's the function....
Public Overloads Function GetClassFromDB(ByVal ID As Integer) As Object
Try
Dim BaseObject As New Object
Dim objDerived As Type = MyBase.GetType()
Dim TableName As String = String.Empty
Dim SQL As New LottoPayload.SQLiDataClass
Dim SQLString As String = String.Empty
Dim SQLCommand As SQLiteCommand = Nothing
Dim SQLConnection As SQLiteConnection = Nothing
Dim SQLiteDRObj As SQLiteDataReader = Nothing
Dim SQLResultsTable As New DataTable
'Create an instance of the base object
BaseObject = Activator.CreateInstance(objDerived)
'Get the tablename from the object
TableName = objDerived.GetProperty("TableName").GetValue(BaseObject, Nothing).ToString
SQLString = "SELECT * FROM " & TableName & " WHERE ID = '" & ID.ToString & "' LIMIT 1"
SQLConnection = SQL.GetSqlConnection()
SQLConnection.Open()
SQLCommand = New SQLiteCommand(SQLConnection)
SQLCommand.CommandText = SQLString
SQLiteDRObj = SQLCommand.ExecuteReader()
SQLResultsTable.Load(SQLiteDRObj)
If SQLResultsTable.Rows.Count > 0 Then
For Each Row As DataRow In SQLResultsTable.Rows
For Each Column As DataColumn In Row.Table.Columns
Dim ColumnName As String = Column.ColumnName.ToString
Console.WriteLine(Row.Item(ColumnName))
Dim ColumnValue As Object = Row.Item(ColumnName)
Console.WriteLine(Column.DataType.Name & " ")
Select Case Column.DataType.Name
Case "Int64"
Dim ConvertedValue As Integer
Integer.TryParse(ColumnValue.ToString, ConvertedValue)
objDerived.GetProperty(ColumnName).SetValue(BaseObject, ConvertedValue, Nothing)
Case "Double"
Dim ConvertedValue As Double
Double.TryParse(ColumnValue.ToString, ConvertedValue)
objDerived.GetProperty(ColumnName).SetValue(BaseObject, ConvertedValue, Nothing)
Case "String"
Dim ConvertedValue As String
ConvertedValue = ColumnValue.ToString
objDerived.GetProperty(ColumnName).SetValue(BaseObject, ConvertedValue, Nothing)
Case Else
Dim ConvertedValue As String
ConvertedValue = "NotSet"
objDerived.GetProperty(ColumnName).SetValue(BaseObject, ConvertedValue, Nothing)
End Select
Next
Next
End If
Return objDerived
SQLiteDRObj.Close()
SQLConnection.Close()
SQLConnection.Dispose()
'Return False
Catch ex As Exception
Return False
End Try
End Function
and this is how it would be called.
Dim objResults As New myapp.objResult
Dim ID As Integer = 3
objResults.GetClassFromDB(ID)
Question #1 - When I return the object from GetClassFromDB objResults is empty eventhough it had data up until the Return objDerived. Why is this the case?
Question #2 - Is there a way I can eliminate that Select Case area and consolidate the code by using reflection?
Thanks in advance for the help.
Shouldn't you be returning BaseObject rather than objDerived, given that objDerived is actually a Type object that represents the type of the object created rather than the object itself? Maybe it would be clearer if you didn't use appalling names like objDerived in the first place.
The problem is that your method returns an object, but you are not assigning it to a variable anywhere. You need to assign the return value of the method to a variable
Dim someVariable As Object = objResults.GetClassFromDB(ID)
Also, your method is strange in that it returns an object if the code runs successfully but a boolean if there is an exception, which you silently swallow (also a bad practice).
You are returning the wrong object. objDerived is a Type, not the object that you are setting. You need to return BaseObject. Also, realize that your code to close and dispose the SqlCommand and Connection won't be hit since it's after the return operator. It's best here to wrap the connection and command in Using clauses which will ensure they will be disposed once they go out of scope. See if the following works:

From your second screen shot, you don't appear to be setting anything to the return of the GetClassFromDB(ID) method. It should probably be something like:
Dim result = objResults.GetClassFromDB(ID)
' Do something with result

You are adding the same parameter twice, once without a value, then with a value. Instead of adding it another time, set the value on the parameter that you already have.
Replace this:
sqlDataAdapDelProtocol.SelectCommand.Parameters.AddWithValue("PTC_ID", PTC_ID)
with this:
sqlParProtocolName.Vaue = PTC_ID
Side note: Always start parameter names for Sql Server with #. The parameter constructor will add it if it's not there so it will work without it, but this is an undocumented feature, so that could change in future versions.

Now when I am running the program I am getting this error. I tried hard but not able to locate what could be the problem the error is:
System.Runtime.InteropServices.COMException -->Horizontal and vertical
pitch must be greater than or equal to the label width and height,
respectively.
Even though I tried to set the Horizontal and vertical pitch programatically it gives same error.
Make sure that you have a default printer set up for the user account that the application runs under. Might not be relevant but I have had various unusual problems following that omission.
Did you install the Office Primary Interop Assemblies? (Appropriately abbreviated to PIA)
