Now i am using Microsoft Access 2016 and suddenly i can't open one of my tables.Its say "Not a valid bookmark".
After using compact and repair,that table is missing.
I can't export the database,That error is always.I have no idea why.
I was checked other answer and It doesn't make clue.
Please help me.
That's a corruption issue. Running C&R is your only method to get it cleaned up.
So, revert to the latest backup, restore data otherwise somehow, or - if essential and valuable data are lost - contact a paid restore service.
A reputable service can be found here.
Not sure if you made a back up before C&R so whether or not you still have that trouble-table.
Create a brand new db. Import into it everything from the problem db EXCEPT that trouble-table. Sanity check that all this behaves ok.
Create another new db - and import into it only the trouble table. It probably still won't open but it might. If it does - export the data out to excel; create a new table in your other new db; and import the data back in. If it does not open try another C&R with this new db file. If still no joy I think you'll have to create a new table.
You'll want to try and determine how this happened - I rarely see a totally corrupt table. A move to a new edition i.e. 2016 - if it is a big jump such as from 2003 - I have seen where things are less forgiving. Be sure if this is multi user that the db application is split and every user has their own front end file - this is the primary cause of corruption these days.

The template comes without database at first. When I launch the application some code must create the db obviously, because I check the appData folder and now it's there.
Can you tell me which part of the code creates it? Thanks. I have long looked at the code and I cannot figure it out.
I think the only answer possible is that entity framework creates the database automatically. But the strange thing is if I remove thee database it does not get recreated, I get an error that says it's missing it.
I have an old setup with a tfs2010 and sql2008 and the current Collection is holding 3 team Projects. Now i want to create a new team project but for some reason i cant. it seems that it has something to do with the SQL Reporting that dosent excists. i get an error TF218027.
Ive been going through the setup and im wondering a bit
What exactly does the TFS use the reportServer for (MSDN dosent seem to want to tell me)
is there any way to create a Team project without the reporting
Will it damage my excisting data if i create and connect to a new sql reportServer
Hope someone will take the time to give an answer
thanks.
I have already tried the different approtaches discussed on different threads and im primarily looking for information on the 3 questions written above
Try the steps below:
In browser go to: http://application-tier/Reports/Pages/Folder.aspx
Press Folder settings button in the toolbar
Press New Role Assignment button in the toolbar
Specify user name in Group or user name field, check Content Manager role and press OK.
So for the people that actually read the question the answer is.
Keeps track of agile work progress
yes and its actually easy. go to the reporting service and stop it and then tell TFS not to report under reporting
Since it was never running the answer here is No
At the early stages of development, where data retention is no issue and experimental changes to the schema are expected to be numerous, is there a way to avoid migration? Namely, just to dump the database and start over each time.
Everything I try leads to the error: "The model used to open the store is incompatible with the one used to create the store".
Lightweight migration looks do-able, but I'll end up lots of unwanted versions and messy code. I'd also like to experiment with relationships (no wise cracks), but understand I'd need to commit to a heavyweight migration afterwards!
If the solution is to check for the existence of the original database using NSFileManager and delete/remove it if found, could someone please show the swift code with an example name of the original database, and how it can be effectively removed.
I've been trying several suggested solutions, such as dragging a copy of the .xcdatamodeld file onto the desktop, deleting the file in xcode and bringing it back in, but I keep getting the error that the model and store are not the same.
Answered in one line in first comment, but appreciated in reverse proportion.
I am having a very frustrating problem with my current project. It is continually losing the connection string binding for Entity models.
I have multiple models for different databases in separate areas and was having no problems. Suddenly now whenever I try to update from the database I get the connection string setup prompt. I select for it to add it to the Web.config with the password but it doesn't ever pick it up there again. They all are still in the web config but it just doesn't see them.
If I remove all the connection strings from the config file it will write the new one there. Then when I try to set up a Stored procedure/Function Import, I still get the statement in the lower box:
No database connection has been configured for this model.
I have tried rebuilding the project and creating the models again from scratch and that works for a while. When I try and bring the project in under Perforce source control, it winds up getting re-corrupted & the connection string goes away. It affects all of my models too.
I am also using EF 4.x DbContext Generator to create context files. They work fine. I am also able to run the application and it connects to the database just fine and returns data. No issues there. I am just unable to update Entity Complex types from the DB or import any more stored procedures.
An even weirder occurrence was that I opened a broken project from a different directory then opened an uncorrupted copy it instantly became broken also. Contagious!
Any thoughts on where to look into to see why this is happening? Has anyone else had this issue?
I seem to have found where the issue is coming from.
I seem to have a bad value somewhere in my web.config which causes the issue. Here is the work around I found did the trick and showed it's the config:
When the binding breaks, I closed the project then swapped out the web.config with one from a good build which was missing a couple keys but worked well enough to bind.
I reopen the the solution and the "No database connection..." error goes away.
Then while the solution is still open I re-swap the web.config back in and it still works.
This is far from optimal but I can work until I figure out the bad value via doing some compares.
I will comment on this again once I determine the exact issue.
I received the source for an application from a guy to make a few changes in the app. The data model version was, say, App3. I had to add about 3-4 more data model versions in the process. So the active model version when I sent him was App7
I built the project (it was running properly on my mac)
I sent him the zip and when he ran, he got the error "Can't find model for source store"
I had him create the latest data model again, based on the data model App3 and make it the same as App7 and set it as the current version.
He still has the error and I can't figure out why? Are the intermediate data model version causing issues? Is it required to delete the sqlite file in the application support->iphone simulator folder? I am all over the place with this. Please help!
You need to have both model files and have some sort of versioning in place. The new model that you made will no longer work with his data file unless you specify to Core Data that you want it to update the data.
Versioning isn't that easy, but if your changes are small enough, you might be able to get away with automatic versioning. Read the guide and see:
http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/Introduction.html
In my understanding, it will. But really that is not the thing to do if ultimately the versioning is going to happen on existing live apps too.
For the light-weight migration to work, you need to send him all the intermediate versions of the model as well since the migration takes place stage by stage through all versions.
And you have to make sure that you have made no modification (even accidentally) to the base version App3.
