Most likely the path you are trying to access does not exist. It seems you are trying to save to a relative location and you do not have an file extension in that string. If you need to use relative paths you can parse the path from ActiveWorkbook.FullName EDIT: Better syntax would also be ActiveWorkbook.SaveAs … Read more
I just discovered the django-jsonfield package, which is a reusable Django field that allows you to store validated JSON in your model. Looks like a viable option to achieve what you want.
This “FileSaver” library may help. If you want it to be reasonably cross-browser, you’ll also need this to implement the W3C Blob API in places it’s not already implemented. Both respect namespaces, and are completely framework agnostic, so don’t worry about naming issues. Once you’ve got those included, and as long as you’re only saving … Read more

When you use the Image.FromFile(strFileName) method to create the Image, the method locks the file until you release the Image. The exact reason is explained below.

Are you sure the pixel format of the Bitmap is System.Drawing.Imaging.PixelFormat.Format32bppArgb? I just stumbled on this question because I was having the same problem, but it was because I was loading an image which had no alpha component to its pixel format. I did Bitmap output = original.Clone(rect, System.Drawing.Imaging.PixelFormat.Format32bppArgb); and it properly saved the PNG … Read more

This can be handled by overrwriting onSaveInstanceState(Bundle outState) in your activity and calling saveState from the webview: @Override protected void onSaveInstanceState(Bundle outState) { webView.saveState(outState); super.onSaveInstanceState(outState); } Then recover this in your onCreate after the webview has been re-inflated of course: @Override public void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.blah); WebView webview = (WebView)findViewById(R.id.webview); if (savedInstanceState … Read more
I generally use this rule of thumb: If you have to modify data so that the save won’t fail, then override save() (you don’t really have another option). For example, in an app I’m working on, I have a model with a text field that has a list of choices. This interfaces with old code, … Read more
