patterns & practices - HiloJS: a Windows Store app using JavaScript

Commented Unassigned: Exception is thrown when Pictures folder is empty [3]

fmartinez — Fri, 03 May 2013 17:25:33 GMT

If the __Pictures__ folder of the current user doesn't contain any images when the sample is run, the following exception is thrown:
```
Exception is about to be caught by JavaScript library code at line 38, column 13 in ms-appx://microsoft.sdksamples.hilo.js/Hilo/Picture.js

0x800a138f - JavaScript runtime error: Unable to get property 'name' of undefined or null reference

If there is a handler for this exception, the program may be safely continued.
```
This exception is being thrown inside the __PictureConstructor__ function (of the __Picture.js__ file) due to the __file__ argument being ___undefined___.

Comments: Hi, I've found that the problem was related to the __processNextFile__ function in the ___createViewModels__ function from the __imageQueryBuilder.js__, which was trying to call the __Hilo.Picture__ function on an invalid index of the array from the Pictures folder. In order to workaround this issue you can change the code from the __processNextFile__ function for the following one: ```JS function processNextFile() { if (index < 0) { complete(results); } else if (!proceed) { error("Cancel"); } else { var file = files[index]; results[index] = new Hilo.Picture(file); index--; setImmediate(processNextFile); } } ``` Regards, Federico Martinez http://blogs.southworks.net/fmartinez

Commented Issue: C:\Projects\Repositories\.bin\hilojs\Hilo\Hilo.jsproj : error : Error HRESULT E_FAIL has been returned from a call to a COM component. [2]

I cannot open the .sln from Visual Studio as the Hilo project fails to load with:

C:\Projects\Repositories\.bin\hilojs\Hilo\Hilo.jsproj : error : Error HRESULT E_FAIL has been returned from a call to a COM component.

Any thoughts,
-Roberto
Comments: I found out what the problem was, it seems the HgSccPackage (http://www.newsupaplex.pp.ru/hgscc_news_eng.html) doesn't like the HiLo .jsproj. I set my Visual Studio to not use any Source Control Provider, and now everything is peachy. Regards, -Roberto
