تقسيم قاعدة بيانات


الردود الموصى بها

السلام عليكم ورحمة الله وبركاته

قمت بتقسيم قاعدة بيانات  لدي وهي تعمل جيدا على الجهاز الخاص بي

ولكن عند نقل القاعدة إلى مجلد جديد أو جزء آخر من الهارد أو إلى جهاز آخر لا تتعرف على المكان الجديد للجداول

فها من طريقة تجعل الامر سهلا بحيث لا تحدث هذه المشكلة عند تغيير مكان قاعدة البيانات حتى لو اردت وضع الواجهة في مكان والجداول في مكان آخر

ارجو من حضراتكم التوضيح

 

شكرا لكم

نعم ممكن تفتح الواجهة وتذهب للجداول وتضفط يمين وتختار ادارة الجداول المرتبطة وتحدد الكل وتختار المسار الجديد في كل مره تغير فيها مكان الجداول

وعليكم السلام أخي علي  :smile:

 

لقد قمت بالرد على هذا الموضوع في منتدى الفريق العربي للبرمجة ، وهنا اضع لك نفس الرد  :smile:

في برنامج الواجهات ، وليس برنامج الجداول ،

'-----------------------------------------------
'VERSION 2 BETA
'- Supports both 32-bit and 64-bit versions of Access 2010.
'- Supports encrypted (password-protected) back-end Access databases.  The password is stored in the front-end database unencrypted, so care should be taken to protect the front-end application.
'-----------------------------------------------
 
'This database contains the module and macros necessary to implement an automatic linked Access table validity checker.
'It also allows the user to change the current backend databases (whether currently valid or not).
'You can try this feature using the ChangeTableLinks macro.
 
'This utility supports multiple back-end Access databases.  It does not need a separate "list of tables" in a table,
'INI file or anywhere else.  In order to have it check and relink new tables, just link them.
 
'This version of the utility supports only Access linked tables.  It does not support ODBC tables such as SQL Server,
'SharePoint linked table, or any other kind of linked tables.  Linked tables other than Access tables are ignored.
 
'To implement, import all modules and macros into an Access database.  If there is already an AutoExec macro,
'copy the one line from this one into the existing one.
 
'Note: Since Access doesn't always refresh the TableDefs collection when a new table is first linked,
'you may need to close and reopen the database when you first link new tables so that the utility will detect them.
 
'On startup, all linked tables will be checked automatically.
 
'For slow networks, or for databases with many (say over 100) linked tables, you can use the "Quick" mode.
'This checks only 1 table in each backend database, and assumes the rest are okay.
'You can use this mode by calling jstCheckTableLinks_Quick.
 
'To change backend databases, even if the current one is valid, have a form button invoke the code:
'jstCheckTableLinks_Prompt
'This can be useful for switching the backend database between Production, Test and Training, for example.
 
'For any selected mode (Full, Prompt or Quick) a fourth, optional parameter called CheckAppFolder forces table links
'to a database that resides in the same folder as the application.  For example, if a table in ProjectApplication.mdb is
'linked to \\Server\Share\Folder\ProjectData.mdb and there is a database of the same name in the same folder
'as the application, then the table link will be changed to reference the ProjectData.mdb file in the application folder.
'This behavior overrides all prompting for a new location; tables linked to a database in the same folder as the
'application will never be prompted.  This mode is helpful for local "work databases" or single user applications.
 
'If you are using the Display Form default in Access you will need to change that default to (None) so that the
'AutoExec macro will execute to link the files before your first form is displayed.
'To get the form you want to display after the files are linked you need to add a line of code to Open Form
'at the end of the AutoExec.
 
'This code requires the DAO library to be selected in your References List (e.g.  “Microsoft DAO 3.6 Object Library”)
 
'For more information from the function (such as whether the links are okay and whether the user changed them) call
'Sub jstCheckTableLinks directly and check the value of its output parameters.  See the comments in the Sub for more
'details.
 
'This utility has been used successfully in Access 95, 97, 2000, XP/2002, 2003, 2007 and 2010.  It works with MDB and
'ACCDB back-end databases.  To link to ACCDB/ACCDE back-end databases, this code must be running in an ACCDB/ACCDE
'front-end application.
 
'This utility contains some techniques that are backward compatible with older versions of Access, such as InStrRight.
 
'You may use and distribute this code in your own applications, provided that you leave all comments and notices intact.

اعمل Macro ، واحفظه باسم autoexec (هذا معناه بانه سيكون اول شئ يشتغل في قاعدة البيانات لما تفتح) ،

في السطر الاول اختر:

Runcode
ثم ضع السطر التالي كاسم للكود:
jstCheckTableLinks_Full()

 

وبعدها تقدر ان تضع سطر آخر ليفتح اي نموذج.

 

الكود سيفحص الجداول ، واذا لم يجد الرابط ، فسيفتح نافذة يسمح للمستخدم ان يختار برنامج الجداول ومساره ، وبسهولة smile.png
