Running an Excel Macro via C#: Run a macro from one workbook on another?
I found a solution that I'd like to share. First, I removed the bit where I opened Worksheet01. I then had my automated script save the .CSV to My Documents. I then used the code I had to open Worksheet01 to open the downloaded file. The key thing at this point is that Worksheet01 is in the Documents folder with Worksheet02. Lastly I used the code to run the macro from Worksheet01, which runs on Worksheet02.
public void WebTest_CodedStep()
{
// Object for missing (or optional) arguments.
object oMissing = System.Reflection.Missing.Value;
// Create an instance of Microsoft Excel
Excel.ApplicationClass oExcel = new Excel.ApplicationClass();
// Make it visible
oExcel.Visible = true;
// Define Workbooks
Excel.Workbooks oBooks = oExcel.Workbooks;
Excel._Workbook oBook = null;
// Get the file path
string path = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
path = path + "\\Worksheet02.csv";
//Open the file, using the 'path' variable
oBook = oBooks.Open(path, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
// Run the macro, "First_Macro"
RunMacro(oExcel, new Object[]{"Worksheet01.xlsm!First_Macro"});
// Quit Excel and clean up.
oBook.Close(false, oMissing, oMissing);
System.Runtime.InteropServices.Marshal.ReleaseComObject (oBook);
oBook = null;
System.Runtime.InteropServices.Marshal.ReleaseComObject (oBooks);
oBooks = null;
oExcel.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject (oExcel);
oExcel = null;
//Garbage collection
GC.Collect();
}
private void RunMacro(object oApp, object[] oRunArgs)
{
oApp.GetType().InvokeMember("Run", System.Reflection.BindingFlags.Default | System.Reflection.BindingFlags.InvokeMethod, null, oApp, oRunArgs);
}
I ran this C# VSTO code to invoke a VBA Macro, this is the syntax I use:
this.Application.Run("mymacro");
Edit:
Macros are Workbook wide, perhaps you need to make Sheet2 the active worksheet before running the macro, eg:
foreach (Worksheet worksheet in workbook.Sheets.ComLinq<Worksheet>())
{
if (worksheet.Name == "Sheet2") worksheet.Activate();
}
