c# - Clean messages in Windows Message Pump -

-

i don't know windows message pump guess events triggered using message pump.

1) when web browser control navigates websites ,it creates different events of document completion, once have got needed in webbrowser_document_completed(),i want ignore further document completion.how can it?

2) if show messagebox() in document_completed(...), shows multiple message box,shows runs on parallel threads.but when debug ,i find run on main thread.so when other 2 threads created?

3) @ same time ,when press close ,it closes window process still running in background, not using other thread still see 2 other threads when debug. lot.

the direct way intercept , evaluate messages being propagated control overriding it's wndproc() method. little bit of debugger observation can identify wm_message constant corresponds target event , alter execution flow accordingly. there pretty example of on msdn site: https://msdn.microsoft.com/en-us/library/system.windows.forms.control.wndproc%28v=vs.110%29.aspx?f=255&mspperror=-2147217396

to idea of message(s) seeing/looking for, reference: http://www.pinvoke.net/default.aspx/constants/wm.html

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
