Re: opening Excel 2003 file by c#

Re: opening Excel 2003 file by c#

Hy,
I did something like what you want in VC++ .NET Framework language. Just use the same classes in C# and it should work (there are some peaces of code that are usefull in my application but do no refer to Excell handling - just not care of). Please note that you have to install Excel 2003 and Windows XP or higher in the system where the application runs.

private: System::Void button7_Click(System::Object^ sender, System::EventArgs^ e)
{
String^ XlsFile = String::Format("Z:\\Documenti\\Lavoro\\Fatture\\2009\\Fattura_02_AEM_marzo_09.xls");
String^ XlsSheet = String::Format("Milano, {0}/{1}/{2}",
dateTimePicker1->Value.Day.ToString(),
dateTimePicker1->Value.Month.ToString(),
dateTimePicker1->Value.Year.ToString());

Excel::Application^ oXLApp;
Excel::Workbook^ oXLWBook;
//Excel::Sheets^ oXLSheet;
//Excel::Worksheet^ oXLWSheet;

Excel::Range^ rng;

//starts Excel application
oXLApp = (gcnew Excel::Application());
oXLApp->Visible = true;
//opens the workbook of the file "XlsFile"
oXLWBook = oXLApp->Workbooks->Open(XlsFile, 0, false, 5, "", "",
true,Excel::XlPlatform::xlWindows, "\t", true, false, 0, false, true, true);
//updates the range of sheet1, cell D4
rng = oXLApp->Range::get("D4","D4");
rng->Value2 = XlsSheet;

}
