Creating chart in Excel:

The class "cExcelChart" does everything, just use this class.

Using example:This will create graph and convert graph to image and return image path.

call this code in form:
Dim sGraphQuery As String = "SELECT Periodname,"
sGraphQuery = sGraphQuery & " Instructed,Completed,Cancelled "
'sGraphQuery = sGraphQuery & " Instructed + 8 as Instructed ,Completed + 8 as completed, Cancelled + 8 as cancelled "
sGraphQuery = sGraphQuery & " FROM vwCaseTypeInstructionsCompletionsCancellations"
sGraphQuery = sGraphQuery & " where casetypeid = 0 "

Dim arCols(3) As String
arCols(0) = "Period"
arCols(1) = "Cases Instructed"
arCols(2) = "Cases Completed"
arCols(3) = "Cases Cancellated"

Dim chartTitle As String = "" '"Sale Summary"
Dim xaxisTitle As String = "Period"
Dim yaxisTitle As String = "Instructions"
Dim ChartFullpath As String = System.IO.Path.Combine(chartOutputPath, "ICC_Sale.gif")

Dim sPath As String = generateGraph(sGraphQuery, ChartFullpath, chartTitle, xaxisTitle, yaxisTitle, arCols)

solution for combo box and listbox value and text

define a class for value and text strings and use them to get the information

example as below:

Dim sValue As String
Dim sText As String

Dim mli As MyListBoxItem = CType(cboMonth.SelectedItem, MyListBoxItem)
sText=mli.ToString 'or sText=cboMonth.Text

If cboMonth.Text = "" Then
MsgBox("please select a month")
Exit Sub
sMonth = mli.ToString
End If

Class MyListBoxItem

Protected m_text As String
Protected m_value As Integer

Public Sub New(ByVal Text As String)
m_text = Text
m_value = 0
End Sub

Public Sub New(ByVal Text As String, ByVal Value As Integer)
m_text = Text
m_value = Value
End Sub

Public Property Value() As Integer
Return m_value
End Get
Set(ByVal Value As Integer)
m_value = Value
End Set
End Property

Public Overrides Function ToString() As String
Return m_text
End Function

End Class

Combine file path with out worring about '\' problems

System.IO.Path.Combine does the '\' checking for us, we don't need to worry about \\ problems which occur sometimes.
when building a path string use System.IO.Path.Combine

System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "filename.gif")
will output: fullpath\filename.gif

CDONTS multiple attachments sendmail

CDONTS_Object.AttachFile(Physical_Path_to_File, English_Name_For_File)

Assuming your files already exist on the server:

1) Include the Server.MapPath() or specify the full file path.
It doesn't seem to like virtual paths
2) Set the BodyFormat and Mail Format to Zero(0)
3) Then repeat the Attachfile method for each file

Dim objMail
Set objMail = Server.CreateObject("CDONTS.NewMail")
objMail.From = "test@myserver.com"
objMail.To = "youremail@account.net"
objMail.Subject = "Multiple File Attachments"
objMail.Body = "Intentionally Left Blank"
objMail.BodyFormat = 0
objMail.MailFormat = 0

Call webservice without adding webreference:

1. Create a class as with "DynamicWebService" and new method "CallWebService".
2. Create an object od this class and call method "CallWebService" with web service url and other paramaters.

Create a new class and replace the code for this:

  Singleton   A class of which only a single instance can exist
  Structural Patterns
  Adapter   Match interfaces of different classes
  Bridge   Separates an object’s interface from its implementation
  Composite   A tree structure of simple and composite objects
  Decorator   Add responsibilities to objects dynamically
  Facade   A single class that represents an entire subsystem
  Flyweight   A fine-grained instance used for efficient sharing
  Proxy   An object representing another object
  Behavioral Patterns
  Chain of Resp.   A way of passing a request between a chain of objects
  Command   Encapsulate a command request as an object
  Interpreter   A way to include language elements in a program
  Iterator   Sequentially access the elements of a collection
  Mediator   Defines simplified communication between classes
  Memento   Capture and restore an object's internal state
  Observer   A way of notifying change to a number of classes
  State   Alter an object's behavior when its state changes
  Strategy   Encapsulates an algorithm inside a class
  Template Method   Defer the exact steps of an algorithm to a subclass
  Visitor   Defines a new operation to a class without change

Stored procedure using Cursors

the below is a sample example for stored procedure and cursors

-- declare all variables!

DECLARE @iRowId int,
@vchCustomerName nvarchar(255),
@vchCustomerNmbr nvarchar(10)

-- declare the cursor
FROM CustomerTable

OPEN Customer

FETCH Customer INTO @iRowId,

-- start the main processing loop.
WHILE @@Fetch_Status = 0


-- This is where you perform your detailed row-by-row processing. INSERT INTO ORDER(CUSTOMERNUMBER,CUSTOMERNAME) values(@vchCustomerNmbr,@vchCustomerName)

-- Get the next row.

How to debug classic ASP pages in VS 2005

Here is how to make ASP debugging work:

1. Enable ASP debugging on the server. (IIS 5.1 right click on Virtual directory->properties->Configuration(in directory tab)->debugging tab->enable asp debugging)
2. Open classic ASP in VS 2005.
3. Set breakpoint.
4. View page in browser or run without debugging.
5. Debug | Attach to Process
6. Locate IIS ASP worker process (w3wp.exe on IIS6) which exposes x86 and Script and attach as Script.

When running on XP Pro/IIS 5, you need to attach to dllhost.exe instead of w3wp.exe. look for the one with Type "Script, x86" and the User Name column indicates your IIS process account (IWAM_machinename).

Create, read, write and delete event logs in VB.NET

In .NET the EventLog class from the System.Diagnostics namespace lets you read from existing logs, write entries to logs, create or delete event sources, delete logs, and respond to log entries. This can be useful when errors occur within your code. This code shows how to use the EventLog class.

Imports System.Diagnostics

Dim aLog As EventLog
Dim myLog As New EventLog
Dim aEventLogList() As EventLog
Dim aLogEntry As EventLogEntry
Dim aLogEntries As EventLogEntryCollection
' Create a new log.
If Not EventLog.SourceExists("MyNewSource") Then
EventLog.CreateEventSource("MyNewSource", "MyNewLog")
End If
' Add an event to fire when an entry is written.
AddHandler myLog.EntryWritten, AddressOf OnEntryWritten

With myLog
.Source = "MyNewSource"
.Log = "MyNewLog"
.EnableRaisingEvents = True
' Write a few entries.
.WriteEntry("Writing Error entry to event log", EventLogEntryType.Error)
.WriteEntry("Writing Information entry to event", EventLogEntryType.Information)
.WriteEntry("Writing Warning entry to event", EventLogEntryType.Warning)
' Output all events in the new log.
aLogEntries = .Entries()
For Each aLogEntry In aLogEntries
With aLogEntry
Console.WriteLine( _
"Source: {0}" & vbCrLf & _
"Category: {1}" & vbCrLf & _
"Message: {2}" & vbCrLf & _
"EntryType: {3}" & vbCrLf & _
"EventID: {4}" & vbCrLf & _
"UserName: {5}", _
.Source, .Category, .Message, .EntryType, .EventID, .UserName)
End With
' Delete your new log.
' Output the names of all logs on the system.
aEventLogList = .GetEventLogs()
For Each aLog In aEventLogList
Console.WriteLine("Log name: " & aLog.LogDisplayName)
End With

Public Sub OnEntryWritten(ByVal source As Object, ByVal e As EntryWrittenEventArgs)
