c# - How to refresh image in Image control? -


i trying create desktop viewer. managed take single screenshot , put image control. if try repeat it, program freezes , image doesn't appear.

private void display() {     img.source = screenimage(); // returns bitmapimage }  private void button_click_2(object sender, routedeventargs e) {     while(true)     {           display();     } }

if run display method once works, after calling more times doesn't show anything.

if trying replicate visual changes desktop in image control (make movie of desktop) instead of looping endlessly in click

what should happen if click twice (if click it)?

start timer takes snapshot every second or on background thread.

that way application remain responsive.

your current code claiming ui thread ever , why can't in application after clicking button.

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
