hi,
My name is Aasif.
1.I am a software developer and i stuck somewhere here.. so please help me
I am developing software where i m updating my functions(applying filter eg-setting brightness,contrast,gamma...) on track bar but it is very slow .as soon as the moment i drag trackbar the filters get applied to image in picture box,it does not allow me to go ahead unless filter get applied.also I am using textbox where again the moment i enter value filter gets applied eg- (when i want to enter 1.25 in textbox ,as soon as i enter 1 filter gets applied ,it doesn't wait for 2 and 5)

2.I want to set timer on trackbar and want to link it with progressbar and label so that whenever i drag track bar it should move smoothly and filters get applied and at the same time progressbar and label get updated.
please help me by providing few piece of codes if possible.
