Hi All,

I want to capture my screen and then save it to pdf file which don't use other library.
My solution is: capture my screen to bitmap and then insert this bitmap to excel and export this excel to pdf file.

But there are 2 issues:
1. I captured my screen to Bitmap but I can't insert this Bitmap to excel sheet.
I must save this Bitmap to image file and then insert this image to excel sheet.
-> I want capture screen to bitmap and add bitmap to excel sheet.

2. because my monitor resolution is big therefore, when export to pdf file(xlWorkSheet.ExportAsFixedFormat(...)) my screen is at many pages in pdf file.
-> I want to display my screen after captured on 1 pages of PDF(all fixed on 1 pages).

please help me.

thanks in advance
