Recover Corrupt QVW file

Hi All,

I need your assistance with a corrupt QVW file.

I'm using version 11 SR3 and I have a -prj file linked to SVN with all my xml and text files in the folder.

I created an empty shell for the QVW (Ctrl+N) using the same file name as the original application and I saved it in the same directory as my -prj folder then I close it without any additional saving. Next, I open the QVW again to recreate (populate) the application from the -prj, but all I get is an empty canvas.

Any ideas of what am I doing wrong?

Thanks for your help.

Robert

You are correct.  When I created and saved the empty shell, it overwrote my Qlikview project file in my local repository.

As a result, every time I opened the QVW to recover the application I would get an empty screen.

To solve the problem I had to restore from the SVN repository from a previous committed (138 out of 143) version.  However, this version was missing a few very important changes so I had go to plan B.

Plan B, I copied the application form our development server into a test folder in my localhost where I created another -prj folder to extract the XML files. I then pasted a copy of those XML files into my local SVN repository and then I opened the Application. It worked!  Now, I have to commit those changes to SVN again so I have a good backup.  However, before I commit my changes  I'm going to try NagAviral's suggetion--Plan C.

Thanks.

Re: Recover Corrupt QVW file

Hi Robert,

I think your file has been overwritten with your original File.

in this case your original file has gone you can not recover it.

if your QVW is not able to open and it is showing message like failed to open then there is chance to recover but in your case it is not possible.

it is like your word file or txt file if you overwrite the files the original file could not been revocable.

Re: Recover Corrupt QVW file

Nag,

Thanks for the help, but your approach did not work.

In step 1, the application displays a dialog box with a message stating that the QVW failed to load. Qlikview will not allow you click on any other buttom until you close the dialog box.

Next it displays another dialog box "Qlikview x64" with the message "Failed to open document" Again, you can't get around the dialog box. Once you click the OK button, it tries to reload the application, but you end up with the dialog box found in step 1. Again, you click on the box only to see the "Qlikview x64" diaglog box again. You click the OK button again the dialog box goes away, and now the  Qlikview application closes without giving you a chance to get to step 2 of your instructions.

Re: Recover Corrupt QVW file

Actually, you can try to apply this setting from the QV Desktop Start Menu instead of trying from the corrupted document. Apply the setting, close QlikView, then attempt to open the corrupted application. I haven't had a lot of success with it, but it's worth a try.

Also in QV 10 there was a similar setting called "Layout Rescue". The same steps would apply if you are on that version, but this is not available in QV 11.
