问题 Does anybody know which language or technology was used to develop the Spotify desktop application?

问题 I have a QScrollArea with some buttons in it, like shown on the picture. The idea of the layout is: 1. The left and right button should be used for scrolling the buttons when they are too wide 2.The numbers of buttons in the scroll area can be changed dynamically 3.

阅读更多关于 Writing custom code for PowerPoint using leap motion?

问题 I am trying to make a gesture based PowerPoint slideshow . JavaScript would certainly not work here as I want my slideshow to work when that particular PowerPoint file (.ppt) is opened for windows. I googled, posted a question on the Leap Motion forum, but in vain. My primary concerns are: I am unsure about what to use here. Are there some SDKs for this purpose? In simple words, how do I write some custom code for a PowerPoint file on our system? Leap Motion apps can be developed with C#, C++

Using ELMAH in a console application

阅读更多关于 Using ELMAH in a console application

I just started using ELMAH and am a fan. My team supports a large number of web applications and I'm particularly excited that ELMAH lets us save exceptions from each application to the same MS SQL database table. We also support a few console, DLL and desktop applications. Is it possible to use the ELMAH DLL to log exceptions in these apps to that same location? We have exactly the same situation here. Running ELMAH for all our web applications. A few of them have console based schedulers. After doing some digging through the source code, the following code seems to work: ErrorLog errorLog =

问题 I'm working with a system that has 4 outputs (monitors) with e.g. 1280x1024 pixels for each output. I need a screenshot of the whole desktop and all open applications on it. I tried GetDesktopWindow() (MSDN) but it doesn't work properly. Some forms don't shown on the captured picture. 回答1: i tried GetDesktopWindow() function but it doesn't work properly. Of course not.

阅读更多关于 What's the best way to watchdog a desktop application?

问题 I need some way to monitor a desktop application and restart it if it dies. Initially I assumed the best way would be to monitor/restart the process from a Windows service, until I found out that since Vista Windows services should not interact with the desktop I've seen several questions dealing with this issue, but every answer I've seen involved some kind of hack that is discouraged by Microsoft and will likely stop working in future OS updates. So, a Windows service is probably not an

Packaging a node.js webapp as a normal desktop app [closed]

阅读更多关于 Packaging a node.js webapp as a normal desktop app [closed]

问题 I\'ve searched a bit but can\'t find an existing tool for this. I have a node.js web server that is designed to run on your own computer that does some snazzy things for you. It would be pretty aswesome if I could double click MySnazzyThing.app instead of installing nodejs, and npm and running node mysnazzyapp.js on the command line. The .app executable would spool up the node server and open a simple native webkit window which would show what would normally be on localhost:3000 if I were

阅读更多关于 “Automatic updates” for Java (desktop) application?

问题 What system do you recommend for implementing \"automatic updates\" for some java (desktop) application? I\'d also want to have module/plugin installation and update. Think Eclipse and Firefox. I\'m aware of Eclipse RCP\'s OSGi stuff, and also NetBeans RCP has something here. Do one have to buy wholly into their respective RCP stuff to use their module and automatic update systems? Are there other options? 回答1: Have you looked at the Java Web Start? It checks for updated module on the server
