i under impression dispatcher follow priority of operations queued , execute operations based on priority or order in operation added queue(if same priority) until told no case in case of wpf ui dispatcher . i told if operation on ui thread takes longer duration database read ui dispatcher simple tries execute next set of operations in queue. not come terms decided write sample wpf application contains button , 3 rectangles, on click of button, rectangles filled different colors. <stackpanel> <button x:name="fillcolors" width="100" height="100" content="fill colors" click="onfillcolorsclick"/> <textblock width="100" text="{binding order}"/> <rectangle x:name="rectangleone" margin="5" width="100" height="100" fill="{binding brushone}" /> <rectangle x:name="rectangletwo" margin="5" wi...

so there's system app , i've sideloaded apk on top of it. possible through adb uninstall sideloaded apk , have system app running? i tried 2 methods failed. using 4.4 a. removed sideloaded app /data/app folder , rebooted. system app stayed in comatose state. b. did adb uninstall (success) , rebooted. same result. this convoluted approach did it. move system apk /system/priv-app/ /sdcard/ adb uninstall reboot move system app /sdcard/ /system/priv-app/ reboot my question is, there straightforward approach doing through adb? since installed same package (app) on top, adb package manager removed old system app (same package name). you can see list of current apps/pacakges adb shell pm list packages if have old .apk , can reinstall adb install -r <apk> again. http://developer.android.com/tools/help/adb.html if see failed version downgrade , try -d adb install -r -d <apk>

how istream struct contains vector of integer member, tried following code failed read file struct ss{ std::vector<int> a; double b; double c; }; std::istream& operator>>(std::istream &is, ss &d) { int x; while (is >> x) d.a.push_back(x); >> d.b; >> d.c; return is; } std::vector <std::vector<ss >> aarr; void scandata() { ifstream in; in.open(fileinp); std::string line; while (std::getline(in, line)) { std::stringstream v(line); ss s1; std::vector<ss > inner; while (v >> s1) inner.push_back(std::move(s1)); aarr.push_back(std::move(inner)); } } i did search similar problems not find one. the immediate problem here same condition terminates while loop prevents successive reads working. stream in error state. double values never read. actually, integer part of first double read i...

i have tried making drawmodel method using foreach loops: void drawmodel(model model, vector3 modelposition) { foreach (modelmesh mesh in model.meshes) { foreach (basiceffect effect in mesh.effects) { effect.lightingenabled = true; effect.enabledefaultlighting(); effect.preferperpixellighting = true; effect.world = matrix.createtranslation(modelposition); effect.projection = cameraprojectionmatrix; effect.view = cameraviewmatrix; } mesh.draw(); } } any ideas on missing?

let's have following function/method, calculates bunch of stuff , sets lot variables/attributes: calc_and_set(obj). now call function several times different objects, , if 1 or more fails nothing should set @ all. i thought this: try: calc_and_set(obj1) calc_and_set(obj2) calc_and_set(obj3) except: pass but doesn't work. if instance error happens in third call function, first , second call have set variables. can think of "clean" way of doing want? solutions can think of rather ugly workarounds. i see few options here. a. have "reverse function", robust. if def calc_and_set(obj): obj.a = 'a' def unset(obj): if hasattr(obj, 'a'): del obj.a and try: calc_and_set(obj1) calc_and_set(obj2) except: unset(obj1) unset(obj2) notice, in case, unset doesn't care if calc_and_set completed or not. b. separate calc_and_set try_calc_and_set , testing if works, , set , won't throw ...
