This VB.NET tutorial will demonstrate one approach to read data from an Excel file and extract it for the SDW. Note that this tutorial is for demonstration purposes only and does not include any exception handling. To complete this tutorial successfully, please use the [[APISDWTutorial|sample Excel data]] that was provided for this exercise.
 
 
 
 
 
== Transfer Data from an Excel File to the SDW (VB.NET) ==
 
1.  Before we begin, you'll need to reference the Microsoft Excel Object Library. Choose '''Project > Add Reference''', and then select the library from the COM tab. Click '''OK'''.
 
2. Create a new form. On the code page, add an Imports statement for Microsoft.Office.Interop.Excel, then start with the following code to create an SDW data collection. The code uses the <code>RawDataSet</code> class to represent an SDW data collection, and the <code>ExtractedType</code> property to specify that the data collection is for use with Weibull++.
 
'''VB.NET'''
{{APIComment|'Declare a new instance of the RawDataSet class.}}
  {{APIPrefix|Dim}} DataCollection {{APIPrefix|As New}} RawDataSet
{{APIComment|'Name the data collection "New Data Collection," and then specify that}}
{{APIComment|'it is for use with Weibull++.}}
  DataCollection.ExtractedName = {{APIString|"New Data Collection"}}
  DataCollection.ExtractedType = RawDataSetType.Weibull
 
3. Next, use the <code>RawData</code> class to represent a single row of data, and then use the <code>AddDataRow</code> method to add the row to the data collection.
 
The following code demonstrates one way to extract a row of data from the Excel file. First, the code opens a connection to the Excel file and specifies the active sheet (in this case, Sheet1). Then <code>For i = 2</code>, the code creates a new <code>RawData</code> object and sets its properties by using the values from row #2 of the Excel file. After the code finishes reading the row of data, it adds the object to the data collection. When the code reaches <code>Next i</code>, it increases <code>i</code> with 1 and jumps back to the <code>For</code> statement, which adds another new <code>RawData</code> object for the data in row #3 of the Excel sheet, and so on. The loop continues until <code>i</code> reaches the specified number of rows (MaxRow).  Finally, the code closes the connection to the Excel file.
 
'''VB.NET'''
{{APIComment|'Declare a new instance of the RawData class.}}
  {{APIPrefix|Dim}} Row {{APIPrefix|As New}} RawData
{{APIComment|'Open the Excel file. The following code assumes that the}}
{{APIComment|'Excel file is saved in the C drive.}}
  {{APIPrefix|Dim}} Excel {{APIPrefix|As New}} Application
  {{APIPrefix|Dim}} Workbook {{APIPrefix|As}} Workbook
  {{APIPrefix|Dim}} Sheet {{APIPrefix|As}} Worksheet
  Workbook = Excel.Workbooks.Open({{APIString|"C:\SampleData.xlsx"}})
  Sheet = Workbook.Sheets(1)
{{APIComment|'Read each row of data in the Excel file.}}
  {{APIPrefix|Dim}} i {{APIPrefix|As}} Integer, MaxRow {{APIPrefix|As}} Integer
  MaxRow = 20
  {{APIPrefix|For}} i = 2 {{APIPrefix|To}} MaxRow
      Row = {{APIPrefix|New}} RawData
    {{APIComment|'Set the properties for the current row of data.}}
      Row.StateFS = sheet.Cells(i, 1).text
      Row.StateTime = sheet.Cells(i, 2).value
      Row.FailureMode = sheet.Cells(i, 3).text
    {{APIComment|'Add the current row to the data collection.}}
      {{APIPrefix|Call}} DataCollection.AddDataRow(Row)
  {{APIPrefix|Next}} i
{{APIComment|'Close the Excel file.}}
  Workbook.Close()
  Excel.Quit()
 
4. Now that the data from the Excel file have been copied to the data collection, the next step is to save the data collection to the Synthesis repository.
 
Connect to the Synthesis repository and then use the <code>DataWarehouse.SaveRawDataSet</code> method to save the data collection to the repository.
 
'''VB.NET'''
{{APIComment|'Connect to the Synthesis repository. The following code assumes that}}
{{APIComment|'a standard repository called "RSRepository1.rsr10" exists in the C: drive.}} 
  {{APIPrefix|Dim}} MyRepository {{APIPrefix|As New}} Repository 
  MyRepository.ConnectToRepository ({{APIString|"C:\RSRepository1.rsr10"}})
{{APIComment|'Save the extracted data collection to the repository.}}
  MyRepository.DataWarehouse.SaveRawDataSet(DataCollection)
 
=== Test the Code ===
Let's verify whether the code can import the data successfully into the SDW.
 
Below is the complete code list for this example. On the Debug menu, click '''Start''' to run the application. Then verify that the data were imported by launching Weibull++, opening the SDW ('''Home > Synthesis > Synthesis Data Warehouse''') and then selecting the new data collection. (You may need to display the StateTime, StateFS and FailureMode columns by right-clicking a column header and choosing '''Select Columns'''.)
 
'''VB.NET'''
{{APIPrefix|Imports}} SynthesisAPI
{{APIPrefix|Imports}} Microsoft.Office.Interop.Excel
  {{APIPrefix|Public Class}} Form1
      {{APIPrefix|Private Sub}} Button1_Click(sender {{APIPrefix|As}} System.Object, e {{APIPrefix|As}} System.EventArgs) {{APIPrefix|Handles}} Button1.Click
      {{APIComment|'Declare a new instance of the RawDataSet class.}}
        {{APIPrefix|Dim}} DataCollection {{APIPrefix|As New}} RawDataSet
 
      {{APIComment|'Name the data collection "New Data Collection," and then specify that}}
      {{APIComment|'it is for use with Weibull++.}}
        DataCollection.ExtractedName = {{APIString|"New Data Collection"}}
        DataCollection.ExtractedType = RawDataSetType.Weibull
      {{APIComment|'Declare a new instance of the RawData class.}}
        {{APIPrefix|Dim}} Row {{APIPrefix|As New}} RawData
 
      {{APIComment|'Open the Excel file. The following code assumes that the}}
      {{APIComment|'Excel file is saved in the C drive.}}
        {{APIPrefix|Dim}} Excel {{APIPrefix|As New}} Application
        {{APIPrefix|Dim}} Workbook {{APIPrefix|As}} Workbook
        {{APIPrefix|Dim}} Sheet {{APIPrefix|As}} Worksheet
        Workbook = Excel.Workbooks.Open({{APIString|"C:\SampleData.xlsx"}})
        Sheet = Workbook.Sheets(1)
      {{APIComment|'Read each row of data in the Excel file.}}
        {{APIPrefix|Dim}} i {{APIPrefix|As}} Integer, MaxRow {{APIPrefix|As}} Integer
        MaxRow = 20
 
        {{APIPrefix|For}} i = 2 {{APIPrefix|To}} MaxRow
            Row = {{APIPrefix|New}} RawData
          {{APIComment|'Set the properties for the current row of data.}}
            Row.StateFS = sheet.Cells(i, 1).text
            Row.StateTime = sheet.Cells(i, 2).value
            Row.FailureMode = sheet.Cells(i, 3).text
          {{APIComment|'Add the current row to the data collection.}}
            {{APIPrefix|Call}} DataCollection.AddDataRow(Row)
        {{APIPrefix|Next}} i
      {{APIComment|'Close the Excel file.}}
        Workbook.Close()
        Excel.Quit()
      {{APIComment|'Connect to the Synthesis repository. The following code assumes that}}
      {{APIComment|'a standard repository called "RSRepository1.rsr10" exists in the C: drive.}} 
        {{APIPrefix|Dim}} MyRepository {{APIPrefix|As New}} Repository 
        MyRepository.ConnectToRepository ({{APIString|"C:\RSRepository1.rsr10"}})
      {{APIComment|'Save the extracted data collection to the repository.}}
        MyRepository.DataWarehouse.SaveRawDataSet(DataCollection)
      {{APIPrefix|End Sub}}
{{APIPrefix|End Class}}
