问题 I've got an HTML email template that's using a kludgy process as follows: Pull data from MySQL and put it into a HighCharts chart Convert the HighCharts SVG to canvas using canvg Render the canvas as a Base64 PNG using canvas.toDataURL All's well and good, the image shows up fine (except for some quirkiness in Internet Explorer), but here's the rub: I'd like users to be able to copy and paste the entire web page into Outlook and send it out as an email. However, Outlook (and a few other

问题 I want to extract the Test #. and the description that follows into two different columns side by side. Currently I have one long string. I want to break the string into two sets and extract only the needed information. I have attached a screenshot to make it more clear.

问题 I am trying to get two strings that contain quotations ("") combined as a character/string vector or with R function paste so I can plug the result in the argument x of writeFormula in openxlsx package.

问题 I've been having a really annoying problem that I suspect is an Android ADT bug (v21.0.0-519525). Let's say I'm working on an Activity with two views - a TextView on top and an ImageView on the bottom. I want to move the TextView from the top to the bottom. If I either click or drag it in the GUI, or I cut/paste it in the XML, everything looks fine on the preview and the XML code, but when I go to run the app, their IDs seem to get mixed up. Code which casts R.id.textView to a TextView throws

问题 I have control bar buttons Copy, Cut, and Paste and they suppose to copy/paste some text/objects from and to clipboard. Copy/Cut works fine. Paste using CTRL+V and context menu works fine as well. But when I'm trying to access Clipboard via control bar button click handler it throws error SecurityError: Error #2179: The Clipboard.generalClipboard object may only be read while processing a flash.events.Event.PASTE event. at flash.desktop::Clipboard/getObjectReference() at flash.desktop:

问题 It would be very convenient if one was able to paste images here, on Stack Exchange instead of meddling with a file dialog. Similar feature was (is?) implemented here, but only for Webkit browsers. I was developing userscript that does that.

Firefox solution: div.addEventListener('paste', function(event){ //I'm actually not sure what

问题 This question already has answers here : Concatenate a vector of strings/character (5 answers) Closed 3 years ago . I was working with the paste command in R, when I found that a <- c("something", "to", "paste") paste(a, sep="_") produces the output # [1] "something" "to" "paste" Which is same as when I print "a" # [1] "something" "to" "paste" So what effect does the sep have on the paste command in R? 回答1: sep is more generally applicable when you have more than two vectors of length greater
