the mfc application looks weird 150% dpi settings on windows 7. when display settings on windows 7 changed 150% following things happen: toolbar gets expanded lot making menu items invisible. in addition, black gap get's introduced between toolbar , application frame (as shown in new) the app used work fine while ago (as shown in old). many changes have been introduced app including integration of devexpress. nothing particularly changed in dpi settings. need in understanding why change might have occurred. , how rid of unwanted zoom effect / dpi effect.

so i'm trying make cash register program takes in array of integer prices , adds them total sale price. here's snippet of code that's important do { system.out.print("enter integer price: $ "); int = in.nextint(); prices.add(i); system.out.println(); } while(in.hasnextint()); for(int i=0; i<prices.size(); i++) { int total = prices.get(i) + prices.get(i+1); } system.out.println(total); my error says "total cannot resolved variable" , earlier didn't when tried make increment in loop i+2 instead of i++. can have no idea how add these variables is right track? for(int i=0; i<prices.size(); i++) { int total = 0; int total = total + prices.get(i); } you're doing 2 things wrong here: int total = prices.get(i) + prices.get(i+1); you're declaring total inside for loop. outside default value of 0 . adding values of current iteration , next iteration. want total = total + prices.get(i); or total += prices

does know of way, programmatically, determine if sql server mysql or mssql installation? i've got app in c# has able connect either mysql or mssql. can connect either if know is, can't tell connection settings because server name, userid, password, , database name. i can have settings file store type of server, opens avenue user error i'd avoid. try connect mysql , if fails, handle error gracefully try connect mssql. loosely similar might work ... string finddbtype(string connectionstring) { try { // try connect mysql return "mysql"; } catch() { try { // try connect mssql return "mssql"; } catch() { return "cannot determine db type" } } } you want handle errors incorrect password separately, should started.

i'm looking feasibility of gpu synthesized audio, each thread renders sample. puts interesting restrictions on algorithms can used - algorithm refers previous set of samples cannot implemented in fashion. filtering 1 of algorithms. bandpass, lowpass, or highpass - of them require looking last few samples generated in order compute result. can't done because samples haven't been generated yet. this makes synthesizing bandlimited waveforms difficult. 1 approach additive synthesis of partials using fourier series. however, runs @ o(n) time, , slow on gpu point gain of parallelism lost. if there algorithm ran @ o(1) time, eliminate branching , 1000x faster when dealing audible range. i'm looking dsf sawtooth. i've been trying work out simplification of fourier series hand, that's really, hard. because involves harmonic numbers, aka singularity of riemann-zeta function. is constant-time algorithm achievable? if not, can proven isn't?

i'm converting unity 4 project unity 5. understand interactivecloth has been changed cloth rendering performance reasons. in old project, saving mesh of interactivecloth, can restore default state when level starts over // save mesh netmeshsave = net.mesh; public void resetnetmesh() { unityengine.object.destroyobject(net.mesh); net.mesh = (mesh)mesh.instantiate(netmeshsave); } is there preferred way mesh cloth , restore in unity 5? i can see cloth.mesh no longer exists in unity 5 api this best workaround i've found far. restores cloth's mesh default state, not arbitrary saved state: public void resetnetmesh() { net.getcomponent< skinnedmeshrenderer>().enabled = false; net.getcomponent< cloth>().enabled = false; net.getcomponent< cloth>().enabled = true; net.getcomponent< skinnedmeshrenderer>().enabled = true; }

in understanding, here's how mri 1.9 gil works: interpreter spawns new thread calling corresponding underlying c function , ask acquire "gil". if "gil" free, happy. if not, new thread wait , invoke separate timer thread set "timeslice" when current executing thread hit boundaries such return or checking backward branches, interpreter checks timer decide if context switch should happen. however, pointed article , can guarantee atomicity pure c implementing. being said, if parts of our thread contains ruby code, still in danger of race condition. my question if thread needs acquire gil before executing, why c implementation methods guarantee atomicity? thank in advance! the gvl guarantees 1 thread can execute ruby code @ same time . of course different ruby threads can execute ruby code @ different times. besides, majority of ruby implementations doesn't have gvl anyway.
