LoadUserSettings/SaveUserSetting and History and "Invalid ZIP-format value" SOLVED

[zarkogajic]

Hi support,

At the moment of IPXV_Inst::Init call I do not have access to the file for pUserSettingsSrc or pHistorySrc, so I'm using LoadUserSettings at a later stage. LoadUserSettings accepts only one file (for settings, not for history?).

While the instance is alive, opening documents places them in the history, closing and reopening the controls' host form - and the history is there without me calling for "SaveUserSettings" - so history is automagically maintained during Inst's life. I'm calling SaveUserSettings at app shutdown.

The next time I run the application, the history is lost (other settings are here).

I've tried manually using SaveHistory and this does create the file.

However it seems the history is not picked by LoadUserSettings ?

So, I've tried executing "op.settings.import" right after LoadUserSettings (only "History" set to true) - but I get "AFSLib: Invalid ZIP-format value" on op.Do() call. What's this error about?

I know there's no LoadHistory (yet).

So, should LoadUserSettings load the history as well or not, or ?

How to load the history if I cannot use pHistorySrc in Init ?

Hi Alex,

That is the topic I have followed.

Note:

Hello žarko,

Can you please create a small project that we can debug and find out why is this happening.

Cheers,

Hi žarko.

In the upcoming new 335 build you will be able to use new function:

Code: Select all

IPXV_Inst::LoadHistory(IUnknown* pHistorySrc, LONG nFlags = 0);

pHistorySrc - it can be pointer to IString(full path to the file or to the registry key), or pointer to the IAFS_Name|IAFS_File|IStream
nFlags - is zero by default, but you can specify the PXV_LoadHistory_Merge flag to merge existing history and new one.

Cheers.

Hi Vasyl,

Thanks, sounds great.

Do I still have to provide a sample app for this issue "Invalid ZIP-format value"? I guess you would prefer C#?

Hello žarko,

Yes, we will need a C# project for investigation - it's not urgent though.

Hi Alex,

Ok, will try to prepare it in the coming days ....

Hi Alex,

In the FullDemo, MainFrm constructor, you do "CustomInitSDK" if fLoadPrefs or fLoadHist are set ...

Make sure those are, and have the next code for and after the call to Init :

Code: Select all

    //Inst.Init(null, licKey, prefsPathStr, histFileStr, histThumbsFileStr);
  
    // so we do "plain" init ..
    Inst.Init(null, licKey, null, null, null);
   
   //then we load user settings 
    Inst.LoadUserSettings(prefsPathStr);

    //then we try to load/import the history only
    PDFXEdit.IOperation op = Inst.CreateOp(Inst.Str2ID("op.settings.import"));
    PDFXEdit.ICabNode opts = op.Params.Root["Options"];
    op.Params.Root["Input"].v = histFileStr;
    opts["History"].v = true;
    opts["Settings"].v = false;
    opts["Presets"].v = false;
    opts["TrustedList"].v = false;
    opts["Prompts"].v = false;
    opts["UILang"].v = false;

    try
    {
        op.Do();
    }
    catch (Exception ex)
    {
        PDFXEdit.IAUX_Inst aux = (PDFXEdit.IAUX_Inst)Inst.GetExtension("AUX");
        var error = aux.FormatHRESULT(System.Runtime.InteropServices.Marshal.GetHRForException(ex), 0);
        throw new Exception(error);
        //AV here ...
    }

So, the Init method is called without specifying pUserSettingsSrc, pHistorySrc and pHistoryThumbsSrc.
Then I use LoadUserSettings to load settings from (the same) prefsPathStr and then "op.settings.import" to import only the history from histFileStr.

Op.Do() would raise the mentioned exception "Invalid ZIP-format value".

HTH.

Hello žarko,

Thanks, I will take a look when I have time.

Hi -žarko.

Code: Select all

op.Params.Root["Input"].v = histFileStr;

This will not work definitely because here you need to specify the file that you may get only by using the "op.settings.export" operation.

Cheers.
