问题 I want to add a button in my form(MS Access Database), so it can capture image from my camera(laptop) and save it in a specific location (c:\image).

问题 I've got the URLs in the following style: http://whatever.com/param1/val1/param2/val2 I want to match all key/value pairs. I tried this pattern: /^http:\/\/whatever.com(?:\/([^\/]+)\/([^\/]+))*$/g It only matches the last key/value pair. Unfortunately, I cannot use code to get the pairs... How can I capture all pairs? 回答1: Try making your match non-greedy by adding a ? after the * : /^http:\/\/whatever\.com\/(?:([^\/]+)\/([^\/]+)\/?)*?$/g 来源： https://stackoverflow.com/questions/7187909/select

问题 I'm working with Kofax Capture Workflow Agents. I have installed some WFAs before, but they didn't run on first try and I'm not really sure what I've done to get them working. Currently, I follow these steps to install my WFA: Compile my Source-Files to one DLL Remove Workflow Agent from Batch Classes Uninstall Workflow Agent over Tools > Workflow Agents Copy over to my Test-Environment Install Workflow Agent over Tools > Workflow Agents Add Workflow Agents to Batch Classes Publish Batches

问题 I have a dynamically constructed editable XUL tree. The problem is - how is one supposed to listen and capture the changed cells? I detect the submitting of the edited value by capturing blur event of the tree.inputField , any other events are not working. At least it works, but is there an easy way to retrieve new value? Should it really be as hackish as getting the Tree element, calculating the current cell, and querying its new value? 回答1: I guess that "dynamically constructed" means that

问题 I don't have a C background, so pointers seem to be my downfall. Working with a Lenovo Thinkpad tablet running full blown Windows (Atom processor). I ported the sample project DXSnap to vb.net. It works fine on my laptop, but on the tablet I'm getting errors. First error is: Exception Occurred: System.Runtime.InteropServices.COMException (0x80070032). The request is not supported. 2nd error (after closing 1st error): Uninitialized Buffer in BufferCB. I think the main problem is I'm not sure

问题 I'm trying to make a screenshot capture App. The App will first place a semitransparent full screen dark view over other Apps, this will make other Apps not responding to mouse scrolling event. How can I set a view covers other Apps and keep them respond to scrolling event? Thanks. Ignore MyApp's dark view? or Send event to other Apps in MyApp? -(void)scrollWheel:(NSEvent *)theEvent { NSLog(@"user scrolled %f horizontally and %f vertically", [theEvent deltaX], [theEvent deltaY]); } Edited:

问题 I am developing an kind of outlook calendar application where I need to make the appointment resizable from mouse. My first try with a thumb did not work properly so I tried another way. What I did is that: 1) on the botton of the appointmennt panel I added a rectangle to figure out the resize zone (the thumb). The appointment panel is put on a grid panel. 2) I intercept down event on the rectangle and send event to this code: private Point startPoint; private void OnResizeElementMouseDown

问题 I have a button. On Button.MouseRightButtonDown, I'm calling Mouse.Capture(button), because I want to detect if someone releases right-click outside of the Button. I also have a Button.MouseLeave event registered. If someone right-click-drags the mouse off the button, I want this event to trigger. Unfortunately, it seems like Mouse.Capture somehow blocks MouseLeave from occuring. Does anyone know a workaround, or maybe can point out where I'm going wrong? (By the way, if anyone's curious what
