error อันนี้ละครับ IO Exception was unhandled
The process cannot access the file 'D:\Working\Project4\ProgramProject\ProjectApp\ProjectApp\ProductNewName\21_10_2010_31_29.jpg' because it is being used by another process.
มันเเจ้งประมาณว่าใช้ รูปภาพนี้อยู่ช่ายม่ะครับเลยลบไม่ได้แต่ผมก้อได้ทำการ
Pb_ProductImg.Image.Dispose()
หน้าลบรูปของสินค้าก็ทำได้แต่พอมาหน้าแก้ไขสินค้าใช้โค้ดแบบเดี๋ยวกันแต่แค่มีการ save มาทีหลังกลับ error ครับ
