Обсуждение: Working on problem, thanks for driver help
I tried 8.01.02 to replace my old one, but the problem persists. I will keep trying newer versions, but I thought I might post a description of the problem in the meantime in case someonehas seen it or has suggestions. In my app. I have a subform which has a tab control with student information, and the form source is table tStudents, a postgrestable. This form is embeded in another form, fMain. Odd thing is, if I do a Ctrl-V to paste text into a text box on the tab, the form moves to a new record and pastes the datathere instead of to the original record that was displayed! The form has moved to the new record before the 'beforeupdate' event of the text box has fired. This happens if I paste into a box on either tab page. You don't notice it at first because all the rest of the boxes continueto display the data of the original record, until you click on another tab. Then all the boxes show the new unwantedrecord, and there the pasted data is. Ctrl-X (cut) has the same problem. Things look good at first, then you notice that you removed data from a different recordthat the form has moved to! It doesn't happen when I copy all the postgres data into a local access table and then use it as the record source insteadof the postgres table. This is what makes me think it may be an odbc driver issue. Ctrl-V and Ctrl-X are windows functions (I'm on Win XP Professional, not sure which SP) so concievably Win is part of theproblem. I will set up a box with an earlier version of XP and see what happens. This app has been running smoothly for years, and through several updates to the backend postgres database. Thanks in advance for any help, if I solve it I will post a solution. Fred
Hello, It's hard to understand your problem. When did your problem appear? Show us your ODBC + PostgreSQL relative code.

This is strange indeed. Could be an Access issue though. Which version of MS Access are you using? Also I'm guessing something as bizarre as this could happen if your parent-child relationships between your forms changed and somehow the field you are pasting into or cutting text out of is one of the parent-child fields. What are your parent-child fields set to on your master/sub forms? How this could happen without you actually changing the form is if your postgresql table changed - e.g. you added a field in between another set of fields. Since linked tables do not refresh without explicitly refreshing them, your linked primary key field could very well be now pointing at one of the parent child fields. I would try relinking your postgresql tables to rule that out as an issue.

Thanks for your reply. There is no real code involved in the issue. My main form, fMain, has a subform, fStudent. When the user picks a studentfrom a drop-down list on fMain, fMain sends the subform fStudent the id of the selected student. Upon receiving thestudent id, the subform makes that student record the record displayed for editing by using the code 'Me.RecordsetClone.FindFirst"student_id = " & cstr(id)' followed by (if no error) 'Me.Bookmark = Me.RecordsetClone.Bookmark' This part works as desired. I have stepped through the problem and found that this code is not run when the problem occurs,thus is not causing the subform to move unexpectedly to the undesired record. If the user then chooses to edit the (tabbed control displayed) student data by using the Windows operating system functionsctrl-c, ctrl-v or ctrl-x, the form unexpectedly jumps to a new record before the ctrl-? function acts, and the actionis then applied to the new, unexpected record! As for when it started happening, that is unclear, but probably not too long ago. At first the users thought they were makinga mistake, that they were in error somehow, and didn't bring it to my attention until yesterday. Clearly I need to find out if something was changed in the recent past: upgrade to server, or to workstations (tech supporthas the habit of making changes without telling anyone). One of the techs thinks that a Win XP Office 2002 - Office2007 compatibility upgrade was done recently on the workstations, so I will pursue that as well as whatever else Ior others can think of. Thank you for considering my problem. Fred >>> Andrei Kovalevski <andyk@commandprompt.com> 02/21/2008 1:07 AM >>> Hello, It's hard to understand your problem. When did your problem appear?

This is a resend, pardon if it went already; I got no copy so I suspect it never went. Thanks for your reply. There is no real code involved in the issue.
