External editor in Visual Studio 2008

Is there any way to set up external editor integration for VS2008? By this I mean when I double-click on a .CPP file in the Solution Explorer, it should open in the external editor, not the internal VS one. To keep it simple let's say I want it to open the file in Notepad++ (or how about Notepad to make it even simpler). Right click on the type of file you want in the Solution Explorer, Then choose Open With... Pick your program, and choose "Set as Default" Right click on any file and choose open with.. Then click on add to browse to the program of you choice for this file type and having

Delphi - How to get list of USB removable hard drives and memory sticks?

问题 In my application (Delphi), I need to list all the USB storage devices. These can be either flash memory sticks or external storage drives. There is a Jvcl component JvDriveCombo , and it has the DriveType property - the problem is if I select DriveType := Fixed then in addition to the external drive, it also lists the internal drives ( C:\ , D:\ etc). However, I only want to list the external drives. I believe there is DeviceIoControl function (I saw it on MSDN) but I have no idea of how to

Android - delete files on SD card on uninstall

由 纵饮孤独 提交于 2019-12-02 20:43:38
My app downloads some multi-media files from a server when it's installed. I do this to save space on the size of the app. However, the drawback of this approach is that when the app is uninstalled, it doesn't delete those files. I've seen reports that this is possible, but I can't seem to make it work. Is there a way to do this on uninstall, or should I just forget about it? Note that I have the app installed on the SD card by default as well, but I'm not sure if all phones will automatically support this. Could you download the files and write them to the apps internal space using the

Use Jinja2 template engine in external javascript file

由 ≯℡__Kan透↙ 提交于 2019-12-02 18:12:47
I working on a web project using Python and Flask. I was just wondering if I can access parameters sent by python in my external javascript files? It's working well with html files or with js embedded in html files but not when javascript is extern. See below. The python code @app.route('/index') def index(): return render_template('index.html', firstArg = 2, secondArg = 3) The index.html code ... <body> <p>The first arg is {{firstArg}}.</p> <script src="index.js"></script> </body> ... And the index.js file window.onload=function(){ console.log('{{secondArg}}'); }; So the first arg is correct

External jQuery simply not executing

问题 The code below was fully working when it was placed inside <script></script> tags on the running page. I since moved the code to an outside .js file for organizational purposes which caused the code to stop working - nothing happens when certain events should be fired. I ensured that the script was being included on the given page, and furthermore, I ensured that the link was valid through "view-source" (when I clicked on the script's path, the script loaded in a new window). The script
