continue to shape function during the updating of the old masters and details without validation

< font size = "2" > Hi all.

Suppose we have the following tables
Table 1: used
Table 2: cities

Employee has a foreign key (employee_city_id), see (city_id) in the Cities table.

I do two forms - used and cities - for each table, in the form of the employee, I have run the query and modify some fields so that 'data block used' is CHANGED.
In the second form I do the same thing - run query with the block in the status CHANGED, but when you try to commit the changes in the shape of cities a lock occurs on the table of cities and the form stop working until I have commit the changes in the shape of the employee.

It is not make sense why lock happen?, it as two updated statements for each table.
It should work as what follows, isn't it?
-----
1-
update EMPLOYEE set ...
will the table used in exclusive mode lock 'A LINE' and the table Cities in "UPDATE SHARE" if I change the column refer to the table of cities in the framework.
2-
update CITIES set ...
Release the "update of SHARING" lock in cities if will exist and put in place "exclusive."
-----

So why the form stops working when you apply the above scenario up to approve changes in the form of the employee.
Forms builder version: 6i & 10g
Thank you.
< / make >

you have an index on employee_city_id?
Long ago, I had a similar problem when updating from the main block: If there were no indexes on the secondary table, forms (oracle) locked (or tried to block) the table of any details.

  • STOP: c0000221 {Bad Image Checksum}. The image rpcrt.dll is possibly corrupt and recovery XP says error during the extraction process. Details of error: path not found___

    My friend turned on their laptop packard Bell recently and had the following problem. Windows XP screen loads but is then followed by a blue screen that says STOP: c0000221 {Bad Image Checksum}. The image rpcrt.dll is possibly corrupt. The header checksum does not match the checksum calculated.

    I can't the laptop to go further. I have accessed the Microsoft recovery Panel and try a non-destructive recovery as there are some precious photos that need backup. However, when you select 'no profile' to begin the recovery, I get the message:

    Error during the extraction process. Details of error: path not found

    I'm a bit of a novice when it comes to this sort of thing, but if someone can provide step by step help giving rise to lose photos, I'd be willing to give it a try. I also have XP Home Edition disk that came with the laptop but has never been opened. Any help would be appreciated. Thank you

    You hear your message said something about rpcrt4.dll?  It is important to relay the exact message you see.

    Please provide additional information on your system:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Norton, Spybot, AVG, Avira!, Defender, ZoneAlarm, PC Tools, MSE, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a CD/DVD drive work?

    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

    You use some CD to access this Panel of Microsoft recovery where this "no profile" option is?  I don't know what all this means if it isn't some CD shipped with your system, in which case, I would use it for a coaster instead of something to fix your system.

    If the c:\windows\system32\rpcrt4.dll file is missing or afflicted, you do not start in the last good known Configuration.

    You also will not start in any kind of Mode safe no more.

    Even if you could boot mode safe, you would find that sfc/scannow does not work in Mode without failure in all cases (never).  If you try it, you'll see a message like this:

    Windows file protection could not initiate a scan of protected system files.

    The specific error code is 0x000006ba [the RPC server is unavailable.].

    Failed to start the RPC mode server safe either.

    I can't recreate your error exactly, but it is easy to replace the rpcrt4.dll file.  Looks like you have a working CD drive, so put yourself a Hiren boot CD and when you started on this, you can copy your precious files to a USB device for safety.

    There should be a backup copy of rpcrt4.dll already on your system, here or here:

    c:\Windows\System32\dllcache

    c:\windows\ServicePackFiles\i386

    You need to rename or replace the rpcrt4.dll file which is in c:\windows\system32 and replace it with one you will find the backup copies.

    There should be a backup copy of rpcrt4.dll already on your system, here or here:

    c:\Windows\System32\dllcache

    When you get the Hiren's CD's, you can use to replace the missing or suspicious file.  If you need help with that, first get the Hiren's boot CD made and start over, then we can continue.

    Do you have a Hiren BootCD you can download here:

    Direct HTTP mirror + Torrent, Torrent Magnet

    Click the "Live HTTP Mirror" link to start the download and save the ZIP file on your desktop of somewhere that you can remember.

    The ZIP file is large, so the download will take probably some time to complete.  Then unzip the download to extract the Hirens.BootCD.ISO file that will be used to create your new bootable CD.

    Create a bootable CD. ISO file is not the same as simply copying the. File ISO onto a blank CD.  You must use software that includes how to burn a. ISO to a CD to create a bootable CD.

    File ZIP the Hiren is the file BurnToCD.cmd that you can double-click to launch it.  The BurnToCD.cmd will use the file BurnCDCC.exe to burn the.

    It would be a good idea to test your new bootable CD on a computer running.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.

    These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    When starting on the Hiren's CD, you will see a menu of options.  Choose Mini XP.  It will appear while Windows is loading and you will be presented with a desktop computer that has the look and feel of the interface of Windows Explorer, you are already accustomed to using.

    Using the Mini XP, you can access Internet, maneuvering around your system, search for files, copy files, replace the files and run the scans for malware, edit the text files (like the c:\boot.ini) etc.

    There are dozens of free and useful tools included in the CD that can be used to repair your system or copy your important personal files on another device (like a USB device or an external drive) in the case where you just give up and decide to reinstall your XP (I hope that you will not make this decision)

    Do, or do not. There is no test.

    I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!
