file upload - Uploading content is only supported for 'http' and 'https' schemes -


i'm trying upload file ftp server, i'm using code :

uri uri;         if (!uri.trycreate(serveraddressfield.text.trim(), urikind.absolute, out uri))         {             rootpage.notifyuser("invalid uri.", notifytype.errormessage);             return;         }          // verify not snapped, or can unsnap open picker.         if (applicationview.value == applicationviewstate.snapped && !applicationview.tryunsnap())         {             rootpage.notifyuser("file picker cannot opened in snapped mode. please unsnap first.", notifytype.errormessage);             return;         }          fileopenpicker picker = new fileopenpicker();         picker.filetypefilter.add("*");         storagefile file = await picker.picksinglefileasync();          if (file == null)         {             rootpage.notifyuser("no file selected.", notifytype.errormessage);             return;         }         passwordcredential pw = new passwordcredential();         pw.password = "pass";         pw.username = "username";         backgrounduploader uploader = new backgrounduploader();         uploader.servercredential = pw;         uploader.method = "post";         uploader.setrequestheader("filename", file.name);          uploadoperation upload = uploader.createupload(uri, file);         log(string.format("uploading {0} {1}, {2}", file.name, uri.absoluteuri, upload.guid));          // attach progress , completion handlers.         await handleuploadasync(upload, true);

but sends me exception here : uploadoperation upload = uploader.createupload(uri, file); "an exception of type 'system.argumentexception' occurred in microsoft.samples.networking.backgroundtransfer.exe not handled in user code

winrt information: 'uri': uploading content supported 'http' , 'https' schemes."

your answer right there in exception message.

to quote the documentation:

ftp supported, when conducting download operations.

so can't use backgrounduploader ftp.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
