wpf - C# Async window showing after all code was running -


i trying implement "loading window" wpf-application should shown when client wants send message server , should closed after responce received. use async methods, should not big problem, somehow window shows after response received , closes instantly (as expected).

here code snippets

    public async task<communicationmessage> sendandreadmessagesync(string message, bool showloadingscreen = true) {          // show loading screen if needed         if (showloadingscreen == true) {             await globals.messagecontroller.showloadingscreen(); // method second 1         }          // send message server         sendmessagesync(message);          // receive response server         communicationmessage response = readmessagesync();          // close loading screen         if (showloadingscreen == true) {             await globals.messagecontroller.closeloadingscreen();         }          // return response         return response;     }       public async task showloadingscreen(string title = "lade daten", string message = "einen moment geduld bitte") {          await dispatcher.begininvoke(new action(async delegate {              // create loading screen             loadingscreen ls = new loadingscreen(title, message) {                 ismodal = true             };              // store screen inside list             loadingscreens.add(ls);              // show screen             await this.showchildwindowasync(ls, childwindowmanager.overlayfillbehavior.fullwindow);         }));     }

my thinkings of executions loading screen show independently of sendmessagesync()-method last 10 seconds. after client gets response loading screen closed.

am doing wrong or did forget something? if need more code please let me know

thanks lot!

i suggest encapsulate sending of message in task. right run on ui thread. looks ui thread bussy , cannot show waiting window.

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
