git bash shell on Windows “Your edited hunk does not apply” (continued)

阅读更多关于 git bash shell on Windows “Your edited hunk does not apply” (continued)

问题 Not too long ago, I asked this question. I received an answer, but it did not solve the issue I was having, so I was advised to create a new question with more detail. Just to reiterate, I am getting an error when trying to manually edit a hunk in the Git bash shell on Windows, when using git add -p (specifically, I press e when prompted by the interactive command). This opens an edit file for the hunk in Notepad++ (my default .txt editor). Even without making any changes to this file, I am

阅读更多关于 x-axis zooming with d3 line charts

问题 I'm just getting into using d3, and relatively novice in js still. I'm trying to set up a page of log file visualizations for monitoring some servers. Right now I'm focusing on getting a line chart of CPU utilization, where I can focus on specific time periods (So an x-zoom only). I am able to do a static charts easily, but when it comes to the zooming the examples are going over my head and I can't seem to make them work.

问题 I apologise if the title was confusing, it took me nearly 5 minutes to finally think of a title for this one... Okay, you know how in Visual Studio Express when you add a TabControl to the Form, and you can click on the right-arrow on the top right of the TabControl and it will add a new TabPage , or remove one? Well, I'm creating a User Control where I need people to be able to switch between Panels (my user control is made up of several Panels). I know this is possible as I've used a Ribbon

问题 Is there please a possibility to blend out (hide) a line in Google Line Chart? We have many line charts with multiple series of close data values and my boss asks me to add a way to hide a series (preferably by clicking the line or the legend with a mouse). I have added a select event listener to my very simple test case below (just open it in a browser and it will work), but I'm not sure what to do next: <!DOCTYPE HTML> <html> <head> <script type="text/javascript" src="https://ajax

matlab GOTO (sort of)

阅读更多关于 matlab GOTO (sort of)

问题 I have a long script calling many other scripts that spit out a lot of figures. For debugging purposes I think it would be useful if -when clicking on a picture- the editor goes to a specific line. Does anyone know if this is possible? I thought I could implement something like A=[]; figure plot(x) A=ginput(1) if A~=[] goto(pointer,line) end The problem is that it only would work only right after that the figure is made. Not at the end of the analysis when I take a look to the figures for

阅读更多关于 Creating an Interactive Multi Field Search Bar in MS-ACCESS

问题 I know this is probably a simple thing I'm missing, but I'm hoping you all can help.

The trick is I want the user to be able to type in info and have it check all the fields of the form and return records for any that are valid. I set up a query with the fields that I want checked and I watched a few tutorials on setting criteria, but
