connect to an external sql server from window form

Question

Hi, I am workin' on a small windows application in Visual studio .net using c# and I want to access a ms sql server over the internet... How can I do this? What should my connection string look like?? The servers ip is "skylab1.te.hik.se" port 25000. the server name is "SKYLAB1\INST2" the database name is "BreemerChat". I use Sql server authentication (don't wont to post the logins ;)). earlier I used an alias in the client network utility (wich worked fine) but that doesn't work on other computers, that havn't got an alias... I am a beginner when it comes to this so please help me!

Answer 1

You will need to get reference to the active sheet and set a name to it.

 

Microsoft.Office.Interop.Excel.Workbook workBook;

Microsoft.Office.Interop.Excel.Worksheet workSheet;

 

workBook = XcelApp.Application.Workbooks.Add(Type.Missing);

workSheet = (Microsoft.Office.Interop.Excel.Worksheet) workBook.ActiveSheet;

workSheet.Name = "Sams Report";

Answer 2

I'd suggest you use a free third party library free Spire.XLS to export data to excel, it's easy and doesn't rely on Excel. You can get free Spire.XLS dll from NuGet Package Manager and refer to the following code:

DataTable dt = dataGridView1.DataSource as DataTable;
Workbook workbook = new Workbook();
Worksheet sheet = workbook.Worksheets[0];
sheet.Name = "Sams Report";
sheet.InsertDataTable(dt, true, 1, 1);
workbook.SaveToFile("Report.xlsx", ExcelVersion.Version2013);

Answer 3

Then you have to set the title of the excel application, this will gives you the expected filename when saving

Answer 4

I spoke wrong this is what i need to do without having to save the file.

 

The below code when exporting to excel gives the Book name Book1. How can i edit it to export the Book name as "Sams Report"?
