Sorry Experts,
I'm new to the exchange and this is my first time posting. I just posted the same questions and then awarded points! So, I'm trying again.

I am attempting to create an excel spreadsheet on a vb form using a button. I believe I have the references and import statements correct. However, it throws the error "System.Security.Permissions.SecurityPermission"  when it attempts to execute the first line of code "Dim ex As New Excel.Application".

I have tried to correct it by reading other posts but am lost when it comes to assemblies and changing them.

Any help would be appreciated.

What is your code thus far?  I am relatively new to this as well but actually got a start doing almost this same thing a little while back.

Are you trying to generate a form from scratch or are you modifying a template for you have already created in excel?  I am attaching code  I used on my most recent project doing just this (based off a template though).  Please let me know if you have any specific needs (naming convention for generated forms, .xls files from scratch with formating, etc.
Dim xlApp As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
xlApp = CType(CreateObject("Excel.Application"), Excel.Application)
xlBook = CType(xlApp.Workbooks.Open("Ifyouhaveatemplate.xls"), Microsoft.Office.Interop.Excel.Workbook)
xlSheet = CType(xlBook.Worksheets(1), Excel.Worksheet)

Open in new window

I attempting to create an instance of excel on a vb project form using a push button.

Tried you code and got this:

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Alright just to clarify,  the direction I initially assumed was for creating an instance of excel From your vb form.  Is this correct or do you want the contents to be displayed On the form in an area?

If the first is true, after creating your form you will apply this code to the push button.  Upon pressing the button excel will open with (if specified) your sheet.  Any controls for saving the spreadsheet or modifications to this spreadsheet (ie taking data from your text boxes and adding to cells) will be done in this area as well.  Hope this helps get things rolling.
