c# - How TopMost work when is set to true then back to it's previous state -


i working on legacy c# winforms application , today have found code:

// our current "topmost" value (ours false though) bool top = topmost; // make our form jump top of topmost = true; // set whatever topmost = top;

it makes current form pop-up, seems silly me (even additional comments). have tried in small isolated winforms application, , seems me can safely replaced simple call focus method.

am wrong, or can replace , still sleep tonight?

i appreciate of help!

no, should not focus window. msdn:

focus low-level method intended custom control authors. instead, application programmers should use select method or activecontrol property child controls, or the activate method forms.

perhaps original author didn't know activate, or perhaps had topmost form in app causing nuisance, has since gone away , method of popping fore remnant.. can safely replace activate? don't know enough app ui certain; on face of yes, i've said if existing code works per expectation there seems little mileage gained changing it, , possibly loss of functionality if app acquires other topmost forms on future. i'm sure time better spent on other parts! :)

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
