c# - UWP get shell icon for a file -


most solutions here use system.drawing not available in uwp afaik. getthumbnailasync() job non-image files. image files scaled preview, regardless of passed arguments.

file thumbnails, image , text

i'd have shell file icon instead of tiny preview left of file name, here:

shell file icon

any thoughts?

thanks

ps: have found hack: create 0 byte temp file same extension , make thumbnail of it. hope though there better solution...

well here's helper metod uses dummy file approach (place in static class):

public async static task<storageitemthumbnail> getfileicon(this storagefile file, uint size = 32) {     storageitemthumbnail icontmb;     var imgext = new[] { "bmp", "gif", "jpeg", "jpg", "png" }.firstordefault(ext => file.path.tolower().endswith(ext));     if (imgext != null)     {         var dummy = await applicationdata.current.temporaryfolder.createfileasync("dummy." + imgext, creationcollisionoption.replaceexisting); //may overwrite existing         icontmb = await dummy.getthumbnailasync(thumbnailmode.singleitem, size);     }     else     {         icontmb = await file.getthumbnailasync(thumbnailmode.singleitem, size);     }     return icontmb; }

usage example:

var icon = await file.getfileicon(); var img = new bitmapimage(); img.setsource(icon);

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
