c# - STA for non created Thread/Task -


i made simple async method loading animation while code runs. code runs adds controls stackpanel.

in page_loaded event have:

test();

in test() have

private async void test() {    testbtn.visibility = visibility.visible;    await task.run(() => loadall());    testbtn.visibility = visibility.collapsed; }

and in loadall() dockpanels etc. exmaple:

dockpanel headerpanel = new dockpanel(); headerpanel.lastchildfill = false;

when running error because thread isnt sta thread. how can make sta if dont created thread. (just have await task.run(() => loadall());)

do have create big thread etc. simple animation bar while code runs?

you can run task in scheduler allows safely execute ui code:

private async void test() {     testbtn.visibility = visibility.visible;     taskscheduler scheduler = taskscheduler.fromcurrentsynchronizationcontext();     await task.factory.startnew(() => loadall(),         cancellationtoken.none, taskcreationoptions.none, scheduler);     testbtn.visibility = visibility.collapsed; }

how use roscolor() ignore value (like empty cell) ? color row if value upper 5 when there nothing in cell, want ignore roscolor() apply, how? public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val integer val = quotedatagridview1.rows(i).cells(3).value if val = vbempty quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white elseif val < 5 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.red elseif val > 5 , val < 10 quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.lightyellow end if next end sub you can check empty value following public sub roscolor() integer = 0 quotedatagridview1.rows.count() - 1 step +1 dim val = quotedatagridview1.rows(i).cells(3).value if isdbnull(val) or val nothing quotedatagridview1.rows(i).defaultcellstyle.backcolor = color.white ...

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
