问题 I am trying to use Google HTMLService to process a form from the client side. The tricky part is that I want to capture a pasted image (from clip-board) in the form, send it to the server side and save it in the DriveApp. On the client side, I think I was able to capture the pasted image based on this page: http://joelb.me/blog/2011/code-snippet-accessing-clipboard-images-with-javascript/ And my client side code looks like this: function pasteHandler(e) { // We need to check if event

问题 I've prepared sqlite database in SQLite Manager with all data added manually. This db stored images (BLOB), text and video (BLOB) files.

ByteArrayInputStream inputStream = new ByteArrayInputStream(cursor.getBlob(1)); /

问题 I am running into a strange issue. I have multiple images in my Android project which I stored as .png files under res\drawable. I was able to easily extract the images at runtime and convert them to a bitmap like this: Drawable d = getResources().getDrawable(R.drawable.imageId); Bitmap bitmap = ((BitmapDrawable)d).getBitmap(); This works great and the image gets scaled correctly no matter what screen density the device has. All my images are 200 pixels by 200 pixels and my image layout is

问题 So I'm trying to create and save a binary file locally in javascript using this library: https://github.com/eligrey/FileSaver.js/ It is a bit tricky because I am using GameMaker studio, and the ways I can interact with the javascript is a bit limited, but here's my setup.. Other than the actual filesaver.js from the github repo, my js code is this: var ildablob = new Array(); toArray = function(argument0, argument1) { ildablob[argument0] = String.fromCharCode(argument1); return 1; } save =

问题 Some details off hand: NHibernate : 2.1.2.4000 Oracle Instant client : x64 11.2.0.2.0 Mono : Mono JIT compiler version 2.10.2 I'm currently struggling a bit with Oracle and blobs whereby only 10K of the blob is inserted into the database. While this does work on Windows, there seems to be something different on Linux. Looking at the sql, every thing seems fine. Here is the truncated sql statement. INSERT INTO Voters (Photo) VALUES (:p1);:p1 = 0x424DF627090000000000360000002800000090.... The
