سلام

جرب باستخدم attachdbfilname لكن لابد من وضع مسار ملف قاعدت البيانات كامل وهنا مكانها مع ملف التشغيل applicatin.startupath
وايضا تاكد من AHMED-PC يمكن الاسم مختلف

جرب هذا اولا

كود :

Public con As New SqlConnection(New SqlConnectionStringBuilder() _
                                With {.DataSource = "AHMED-PC", _
                                      .AttachDBFilename = Application.StartupPath + "\GoldData.mdf", _
                                      .IntegratedSecurity = True, _
                                      .UserInstance = True} _
                                  .ConnectionString)

الكود مجرب

او جرب هذا

كود :

Public con As New SqlConnection(New SqlConnectionStringBuilder() _
                                With {.DataSource = "AHMED-PC", _
                                      .AttachDBFilename = Application.StartupPath + "\GoldData.mdf", _
                                      .IntegratedSecurity = True, _
                                      .UserID = "gold", _
                                      .Password = "12345", _
                                      .UserInstance = True} _
