How to deploy resource files for a windows store app

I am working on a windows store app, one of the workflows within the app would allow the user to export a report in html format. The html report relies on a css file so I would like to ensure that the install process could deploy the file in a local folder. If not I would need to read out the file from the assets folder (within the install bundle) and manually write it out but that seems pretty kludgy
https://learn.microsoft.com/en-us/uwp/api/Windows.Storage.KnownFolders?view=winrt-22000
mentions that "The Documents library is not intended for general use." so would require use through file picker but I would prefer to be able to export the document without user intervention without additional store approval headaches (apparently adding Documents library capability to manifest requires additional Microsoft store approval).
Questions
When I create files within the store app it seems the location options are limited and I can only write to Localfolder (which is actually hidden and users cannot easily get to it) - There must be a way to create a file within the MyDocuments directory that is easily accessible by users but looks like that is off limits to a windows store app? So what is the best approach to write reports to storage that can be easily accessed by users
How can one deploy files to a specific directory during install time? Assuming there are some installer commands/manifest directives that would allow this capability?
Or maybe there is a entirely different mechanism to allow for this functionality within the store app and I am just looking in all the wrong places...

Is it possible to upload/choose the file from sharepoint location to application using HTML5 file upload?

I would like to open/select the file from SharePoint location, the file dialogue box(HTML file upload feature) should open with a list of files from the SharePoint directory instead of pointing to the system directory. is it possible?
Currently, the dialogue box opens with the current system directory file location.
Is it feasible with all browsers?
Yes, it is feasible.
However, you might need to custom design the interface.
You would need to perform a rest API call to SharePoint document library to show the list of files. You can use Microsoft Graph API to make the calls and extract the details.

Upload video file (mp4,mpeg) in access database using vb

is it possible to upload video file using access database and vb? i am beginner in programming and our project is all about uploading files. Can anyone help me? I used access database because that is the requirement.
Would the video files be uploaded to a local network server or to a website?
If you are uploading the files to to a local server, you could have access:
1 Open up a file dialog to browse to the file to be uploaded.
2 Copy that file to a specific directory on your network, making sure the filename is unique or possibly creating a file name based on the original file name and date of upload. ie filename_datetime.
See the following answer for steps 1 and 2: storing large numbers of images in ms access
3 Maintain information in a table with fields for: filename, file location, user, upload date, friendly file name and possibly links to other tables such as clientID etc.
If you are uploading the files to a web server, you could do this in access, but you'd probably be better off managing the uploading and listing of files in a website. You could build it yourself or look into what you already have, as many content management systems will have this kind of file management built in.

Is there a way to edit a Google Base Feed?

I just generated an XML google feed from a shopping cart system. I uploaded it to google and I can't find a way of editing it without going via XML. Is there a facility for editing the file without having to deal with large hunks of XML? Can you redownload the file as an Excel file, which is much easier to edit?
what shopping cart system are you using?
Before you upload it to google you can open the file and modify it. if it a txt format you can open it in excel, make sure to save it as a txt file

Is it possible to open an excel file in its current location not download it

I am writing a small web site for a company Intranet and have the following question that may be simple. Is it possible to open an Excel file from it's current location on the network instead of downloading it. So that any changes made are made to the actual file and not a downloaded version of it?
Thanks
Matt
Yes, it's possible, but then you would have to specify the address of the file in the local network, not as an HTTP address on the web server.
The user would naturally need to have access to the file on the network share, with write permission.
No. It is not possible to open a remote excel file across HTTP and write changes back to it.
Let's consider some other things you might be trying to do.
If you are running excel, all you can open are files visible to the file system APIs. That means files on your local disk and network file systems accessible via CIFS. Mapped drive letters, \\ pathnames, that sort of thing.
If you set up an Excel file for download from a web server, it will always be downloaded. Excel won't open it 'in place'.
The Microsoft technology solution that addresses what you seem to be asking for is Sharepoint.
Anything you open from a HTTP connection I believe is "downloaded" to the client. Its more how you "uploade" the changes.
But if thats what the customer wants I have some alternatives:
1) Use Dropbox or similar filesharing utils. Once someone saves a document in Dropbox, its automatically uploaded to the Dropbox account. The free version allows up to 2 GB of data. Thats quite a few Excel files.
2) Use Gmail/Google Apps. If you do you get 1 GB space for online documents. You can upload Office files suchs as Excel and they will be converted an online editable from within the Google Docs. You can share the files within the domain or even externally if you make that setting the admin part. Afterwards you can also download/export the Spreadsheet as Excel format. I havent tested how much of the standards you loose but ofcause its not a full Excel.
3) wait for Microsoft to finish their Office online. I bet that Excel version will do exactly what you are currently asking for by using some special plugin or MSIE9 technics. But I dont really know yet.
Hope some of this gave you some ideas?
If the file is in a network share on the same domain (or reachable from the domain your app is running from), it is possible, provided that
The share is readable and writeable by the domain\user the app runs under (via ownership or assigned role.)
The file is shareable (IIRC). This is important if multiple users (or apps) need to access it.
Other than that, a \domain\location path should be treatable just like a local (or disk mounted) path.
In your HTML document, create/place a link:
<a href='file:///H:/docs/foo/bar.xls'>Your Excel File</a>
Substitite your network UNC path for H:/docs/foo/bar.xls. Note the slashes instead of the regular UNC backslashes.
