i'm having trouble following error: "timeout expired. timeout period elapsed prior obtaining connection pool. may have occurred because pooled connections in use , max pool size reached." it seems error in following code block: da = new sqldataadapter(command); command.commandtimeout = 100; da.fill(dt); conn.close(); return dt; it's hard such small amount of code in question error can occur when you're not disposing of db connection objects properly. "using" statement may out of problem. there issue same error message , code examples here: timeout expired. timeout period elapsed prior obtaining connection pool. may help.

i want use dynamic_cast intrinsic in generated c++ code. macro definition looks like: #define jcast(t, v) (dynamic_cast<t*>(v)) unfortunately, because code generated, situation can occur: foo(jcast(uwiseobject, null)); a compiler said that: error: `nullptr_t` not pointer. how can rescue null in situation? want like: if (v) return dynamic_cast<t*>(v); else return null; well, that's macro's you. write real c++ instead: template<typename t, typename u> t* jcast(u* u) { return dynamic_cast<t*>(u); } template<typename t> t* jcast(nullptr_t) { return nullptr; }

i have qlabel that's displaying rich text (i. e. subset of html supported qt) , uses <tt> tag (for monospaced font). seems mess vertical alignment of whole label text (not monospaced part). as example, here 9 qlabels in grid layout. text of center label "text<tt>label</tt>" , while text of other labels "textlabel" . text of center label aligned 3 pixels lower others. needless say, messes layout , causes annoying layout changes when text changed value doesn't contain monospaced font. how can text align other labels? qt 5.5.1 on ubuntu 16.04 gnome 3.18.2. tl;dr : using <span style="font-family: monospace">...</span> instead of <tt>...</tt> fixed issue me. looking @ following screenshot, impression issue related courier new font: the blue label (top) has font set courier new. has additional space above text. the red label (center) uses <tt> in question. qt chooses courier

although question might sound stupid @ first glance, please hear me out. c#'s get{} , set{} methods increadibly usefull in situations when not know how porgramming goals evolve while build code. enjoyed freedom many time , wonder if there similar methods in bit different light. as working in gamedev, common practice extend/update/improve existing code day-in day-out. therefore, 1 of patterns taught myself follow never use "return" statement more once in of methods. the reason why able write @ bottom of method , sure line have written called 100% of time once method ends. here example: public void update() { updatemovement(); if (isincapacitated) return; if (isinventoryopened) { updateinventory(); return; } if (input.hasaction(actions.fire)) { fire(); return; } else if (input.hasaction(actions.move)) {

i trying solve issue need check whether products in web page loads completely. products load when user scroll page downwards. each time on scroll 8 products loaded. how check in page last product loads , user not able scroll downwards? use known solution scrolling down : webdriver driver = new firefoxdriver(); javascriptexecutor jse = (javascriptexecutor)driver; jse.executescript("window.scrollby(0,250)", ""); then check 8 products after last scrolling iteration doesn't differ current iteration. pseudo-code: products = getproducts(); jse.executescript("window.scrollby(0,250)", ""); // reasonable wait here if(getproducts() == products){ //that it. nothing scroll

i spent 3 hours debugging error , in end narrowed down (i think) variable name. i using initmonths (initial months) caused unpredicatable errors when changed imonths worked! i can understand preventing use of init on it's own surprised if prevented part of variable name. bug or feature? it's not bug if it's related name being overlap. there's part of arc used know when retain counts should updated, , may running that. similar rules apply use new @ start of names (for same reason). it's easy , wise steer clear of using init @ start of names unless it's init function. i can imagine issue related arc getting involved shouldn't , takes while called shouldn't, weird. i expect issue else , name change had other effect. worst case means have memory issue , changing name has changed memory footprint of code you've moved bug somewhere else (or along lines).

i can't figure out how let other people in company deploy (test) server aws elastic beanstalk. this page suggests global permission control on elb: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/awshowto.iam.managed-policies.html the rhys godfrey blog post titled using iam secure elastic beanstalk applications on aws has guidance. we have elastic beanstalk application, , group of users. group of users should able monitor , deploy elastic beanstalk environment, restarting or terminating application instance. should not able change application or environments configuration, or delete environment. user should not able affect other applications or aws services, acceptable them see details on other areas. assume user using aws console. i have reposted iam policies here reference. the nice thing approach considers application environment referencing ec2 tag on instances eg environment=testing , require in use case. { "version&quo

i have makefile including following lines: buildrepo: @$(call make-repo) define make-repo dir in $(c_srcs_dir); \ \ mkdir -p $(objdir)/$$dir; \ done endef on line commands for dir in $(c_srcs_dir); \ following error message: "dir not expected @ moment" make: *** [buildrepo] error 255 i using gnu make . can tell me going wrong? actually for ... in ... ; ... done statement unix command not gnu make command, therefore guess using windows machine (or other one). have find equivalent system. but gnu make has foreach function works : $(foreach dir,$(c_srcs_dir),mkdir -p $(objdir)/$(dir);) also note in specific case (not related gnu make windows) can create dirs without for/foreach loop, : mkdir -p $(addprefix $(objdir)/,$(c_srcs_dir))

i'm trying set graph background dicom image. followed this example , image data given dicom.pixel_array isn't rgba. i'm not sure how convert it, either. i'm not sure bokeh expecting. i've tried finding specifics in documentation, not such luck. from bokeh.plotting import figure, show, output_file import dicom import numpy np path = "/pathtodicomimage.dcm" data = dicom.read_file(path) img = data.pixel_array p = figure(x_range=(0,10), y_range=(0,10)) # must give vector of images p.image_rgba(image=[img], x=0, y=0, dw=10, dh=10) output_file("image_rgba.html", title="image_rgba.py example") show(p) this code doesnt give me errors, doesn't display anything. maybe pixel array doesn't have alpha data, alpha defaults 0 ? i'm not sure. also, can't quite figure out how test it. solved as pointed out, needed map pixel data rgba space. instance, means duplicating data each channel, , setting alpha way. def dic
