SSIS with Excel Source - Generically specify first worksheet?

Question

I have an SSIS package that is reading an Excel source to pipe it to a table in my SQL Server database.
In the Data Flow task, I was able to rename the Name field generically, but with the Custom Properties, I have to specify the rowset name, otherwise the task blows off.
How can I generically specify, hey, do the open row set on the first sheet?

Hi J.D. Walker,
1. You can use the following method to extract data of the first Sheet of the Excel file:
2. Create a string type variable SheetName, and set its default value to the name of the first worksheet followd by $ symbol such as “Sheet1$”. The worksheet name must be valid to obtain the metadata for the OLE DB Source at design-time.
3. Use the ADO.NET Schema Rowset Enumerator of a Foreach Loop Container to get each sheet name of the Excel file, and store the value in variable SheetName by mapping the variable to Index 2.
4. Create an Int type variable Counter, and set its default value to 0.
5. Add a Script Task to the Foreach Loop Container, set the variable Counter as the ReadWriteVariables, and modify the public void Main() function as follows:
public void Main()
// TODO: Add your code here
int cnt = Convert.ToInt32(Dts.Variables["User::Count"].Value.ToString());
cnt++;
Dts.Variables["User::Count"].Value = cnt;
Dts.TaskResult = (int)ScriptResults.Success;
6. Join the Script Task the Data Flow Task, and set the Precedence Constraint as follows:
Evaluation operation: Expression:
Expression: @[User::Count]==1
7. In the Data Flow Task, add an OLE DB Source, create an OLE DB Connection Manager (Native OLE DB\Microsoft Jet 4.0 OLE DB Provider for XLS file, or Native OLE DB\Microsoft Office 12.0 Access Database Engine OLE DB Provider for XLSX file, and set the Extended
Property to Excel 8.0 for XLS file or Excel 12.0 for XLSX file).
8. Set the Data access mode of the OLE DB Source to “Table name or view name variable”, and set the variable to User::SheetName.
In addition, if you want to extract data from the first N worksheets, you can set the expression of the Precedence Constraint above to @[User::Count]<N+1 (replace N with the real number).
