i'm writing "multi-screened" application in c#. "screens" represent different areas of program i.e. settings, restricted access, administration, etc. the problem i'm having when i'm transitioning between 1 panel , another. during transition process, whole form momentarily glitches , outlines of of controls can seen. text on panels appears block background of other panel , other weird things occur. here's screenshots of i'm trying explain... here's panel i'm transitioning should like: and here's happens in transitioning process: i have function use transition between panels. code follows: delegate void dtranspanel(object pan1, object pan2); private void transpanel(object hide, object show) { if (invokerequired) invoke(new dtranspanel(transpanel), new object[] { hide, show }); else { panel h = (panel)hide; panel s = (panel)show; h.hide();

i check dev branch server , made commit , reset '--hard' because should not modify @ branch, not push server. search changes 'git log', see commit still in it. delete dev branch local dev pull again. sure commit not in dev of server side, did exist in history of local dev. --updated-- sure code not in local dev or remote dev, can see log/commit 'git log' in local dev. why reset commit still in history of local history? make sense?

why isn't practice put void(0) when function doesn't return explicitly? function somefunc(a) { // stuffs return void(0); } this when debugging stuffs. thanks. since void(0) resolves undefined , question "why isn't idea return undefined function?". using void(0) alternative undefined bad idea, relatively speaking, because it's more complex undefined , , less explicit. our goal programmers make simple, readable code others read , make sense of. it's bad idea explicitly return undefined function same reason, introduces unnecessary complexity. typeof undefined evaluates undefined . makes writing tests more difficult , gives less insight purpose of function does, say, returning false .

i new regex hence long question. know regex expression codes detect different types of numbers in html paragraph tag. integer number (eg: 0 , 1,000 , 1000 , 028, -1 , etc) floating number (eg: 2.3 , 2.13 , 0.18 , .18 , -1.2 , etc) or regex can combine both 1. & 2. -- integer , float number good! tried solution in stackoverflow results undefined/null, else not detectable already ratio (eg: 1:3:4 detect whole if possible) fractional number (eg: 0/485 , 1/1006 , 2b/3 , etc) percentage number (eg: 15.5% , (15.5%) , 15% , 0.9%, .9%) also, know if regex can detect symbols , numbers together in whole (15.5% , 1:3:4), or must split different parts before detection of number can performed (eg: 15.5 + % , 1 + : + 3 + : + 4 ) ? these different expressions meant written javascript code different exceptions of cases later on. expressions planned used regex detects basic integer in attached javascript snippet below: var paragraphtext

when run git branch command there branch listed (1) appended it, never created branch name , can't delete using git branch -d command. it, , how delete it? :) edit using accepted answer: its invalid have space part of branch name, not clear how got created, if real branch. you can go low level delete branches directly manipulating .git dir. verify it's under .git/refs/heads , remove file .git/refs/heads/gps-feature-branch* under there. perhaps how branch name manipulated in first place (although git wouldn't recognize space in branch name, can add parens here).

i have apache/php/mysql bitnami install running in vm on windows box. can enter ip of vm host machines browser , site-in-progress comes fine. however, need view site in progress device/computer (mobile testing). how can done? a bit late answer think adds value... most vm software has commonly called 'bridged' mode (it's called 'bridged networking' in virtualbox - don't recall it's called in vmware). in essence allows vm it's own independent ip on lan (just 'real' pc). the downside it's not secure (because vm totally exposed network), upside it's quicker , easier set because don't need muck around port forwarding , there no risk of posts conflicting host or other vms. for full details of networking options in virtualbox see page: http://www.turnkeylinux.org/docs/virtual-networking-explained

i observed strange behavior of marker on map while spinning/rotating map 1 direction other. in code have moved map center point upward marker location display current ongoing cursor @ bottom of map per suggestion nikunj in post . seems working fine while in zoomed view , when polylinie drown vertically. when polyline drown towards left or right marker displayed in opposite direction expectation of marker draw on polyline. for placing marker is: getting nearest latlng of polyline current location , assigning marker , animating parking polyline's point. following snapshots of issue. 1) when polyline vertically straight : 2) when polyline in right side : 3) when polyline in left side : if has faced same issue please suggest me solve issue. you need set anchor of image on marker. example: markeroptions markeroptions = new markeroptions() // set options marker .anchor(0.5, 0.5);

i trying create 100% stacked bar chart in android using numetriclabz / numandroidchart library. i have been able draw chart want format things make better since right looking cluttered, tried find solution no avail. i have few questions , great if guys can me out : how can seperate out bars in stacked bar chart / stacked percentage column chart ? how can change colors of bars? how can draw trendline in stacked bar chart ? how put label inside bar? how can remove description @ bottom if want to? is there other chart library should use myself in this, have used mpandroidchart library dont know if has trendline required in project. here code of mainactivity.java : package com.example.android.testingbarchart; import android.app.activity; import android.os.bundle; import com.numetriclabz.numandroidcharts.chartdata; import com.numetriclabz.numandroidcharts.stackedbarchart; import java.util.arraylist; import java.util.list; public class mainactivity extends activity

this might more theoretic question practical one, not make significant difference in runtime of program. @ least not in case. i have received python code imports different ("homemade") functions. 1 function (call func ) called 5 times main script (call main ). in func lot of constants defined in beginning of function. example: import numpy np def func(x,y,z): c0 = np.array([1,2,3]) c1 = np.array([1,2,3]) c2 = np.array([1,2,3]) c3 = np.array([1,2,3]) #do stuff variables x,y,z #return stuff i wondering: when calling function, constants c0,...,c3 defined each time function called, or "fixed" when compiled bytecode when running main script, defined once? yes, defined each time function called. the dynamic nature of python means value of np.array may have changed in time between function's definition , call (and betweeen calls), compiler has no opportunity evaluate them "in advanc
