| Summary | 0002318: TJvFormStorage and TJvListView.Items storage (bug) | ||||
| Description | There is not possible to store "TJvListView.Items" through TJvFormStorage component. Steps: 1. Create new project 2. Put TJvListView component on a form 3. Put a TJvFormStorage and a TJvAppXMLFileStorage components on the form 4. Set "XML" FileName and Location and set AppStoragePath properties of the components. 5. Create some Columnus and add some Items and SubItems into JvListView and 6. Add "JvListView.Items" into StoredProps of the JvFormStorage 7. Finally, compile, run and close application and look at your *.XML file. I suppose there is nothing in XML for JVCL from 12 of Nov. 2004. | ||||
| Additional Information | I can also upload example in BCB6 when it will be requested. | ||||
| Tags | No tags attached. | ||||

Thanks for you description. But i don't have a eays answer for you :-( Until now it's not possible. TListItems will not be stored using the TJvAppStorage by default. Until now you have to reimplemt the feature like hofi has mentioned. For me it's not so easy, to decide what to do. Some possibilities: 1. Do nothing => Not supported => had to be done manually 2. Enhance JvAppStorage.pas to support TListItems => This would mean: include comctrls to the uses of JvAppStorage => NOT Good 3. Enhance JvListView to support the JvAppStorage => Include JvAppStorage to the JvListView.pas file => NOT so bad Any comments or further ideas welcome. |

I have installed version of JVCL from 29.11.2004. It works pretty fine if there are no preset any data in JvListView during design time. It works very nice in this case. If I preset some columnus Items in design time it give me Acces violation error during the second run of the program (data are already stored in *.XML file). Regards Vaclav |

|
Can you please build an sample application for that. In my tests it works without problems. |

Sorry, at the moment I am not able to upload a zipped file, because I have got following error: "The following error was encountered: Write Error The system returned: (32) Broken pipe An error condition occurred while writing to the network. Please retry your request. " ??? The file I'd like to upload has size app. 700KB. I'll try it later. |

> Only upload zipped sources, no binaries please. I believe > 700k is way above the limit I wanted to upload "exe" application with sources. Sources are BCB6 but it should not be problem to convert it to Delphi I guess. There is also included message box image which I got after second start of application. (*.XML file did not exist during its first start) |
|
|
Could you also include a screenshot of the opened application and the created xml-file. I'm not a BCB-User :-) |

Hi Jens I just did a test with the very latest CVS snapshot, both in BCB and Delphi. The bug shows up when starting the application with an existing XML file. I attached the same example converted to Delphi, you should be able to see the bug with the included XML file. |

Thanks Olivier, it was the faster way. The problem is, i can't see anything. I know now that it seems to be not a point of the appstorage code (for me). It seems to be that the av is only raised, when the load happens in the formcreate/formshow process. If you deactivate the active property and load the contents manually by button, there is no problem. So maybe you have an other idea? I didn't know from where the av comes. Greetings Jens |

Hopefully found it (thanks to MadExcept). The error was in TJvListView.WmAutoSelect The WParam Object was no longer in the list, so it raises an exception. I will upload the changes now. Please have a look and give us a feedback. |

|
Hi, my tests are without AV now. ;-) Thanks |
|
|
Great News. So i think we will wait one week again, and then close the case. |
|

Just tested it here, works fine in C++ Builder 6 and Delphi 6 with the latest CVS. |
