i working latest lazarus compiler , have worked synaser serial communication previous version of lazarus. has worked flawlessly, latest version of lazarus synaser code not compiling raising sorts of error. so, question this. there replacement synaser tool lazarus? if not, there update synaser tool? fpc 2.6.2 lazarus 1.0.8 there several serial communication (com port) options available lazarus, first suggest giving synaser try. i'm using lazarus 1.2.4 synaser synapse v40 , latest trunk revision without problems. alternative com port implementations: tcomport port lazarus (cportlaz) serial communications windows api (createfile, readfile, setcommmask, etc) more in hardware access , serial communication lazarus

i see 24 similar questions asking inetaddress.isreachable() instance never returns true, when network otherwise reachable, 1 exception of tests against 127.0.0.1 . if (inetaddress.getbyname("google.com").isreachable(2000)) { system.out.println("visible"); } else { system.out.println("not visible"); } and permissions <uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_network_state"/> this code started within thread (of course). app needs know if specific ip accessible (not google, in above example). behaves same in emulator. is there better way test network connectivity?

i'm trying generate view in code. here's hierachy of view object uiscrollview uiview uibutton the scrollview should same size window. button should big possible. i'm using ios auto layout, constraint strings of objects this h:|[object]| v:|[object]| i've set translatesautoresizingmaskintoconstraints no each object. the problem button gets default button-size. parent view object (uiview) gets size subviews need. red: uiscrollview / yellow: uiview how can force views big scrollview? when use uiview instead of th uiscrollview works great... here's code: - (void) viewdidload { [super viewdidload]; // scroll view uiscrollview* scrollview = [uiscrollview new]; scrollview.backgroundcolor=[uicolor redcolor]; scrollview.translatesautoresizingmaskintoconstraints = no; //container view uiview *containerview = [uiview new]; containerview.translatesautoresizingmaskintoconst...

i trying implement distinct function on arrays this: def distinct(a: array[int]): array[int] = match { case array() => case array(head, tail @ _*) => head +: distinct(tail.toarray).filter(_ != head) } i don't like, have transform tail toarray every time. otherwise compiler complains tail sequence , not array. possible pattern match better in case? it isn't sexy enough pattern matching, go way: def distinct(a: array[int]): array[int] = match { case array() => case htail => htail.head +: distinct(htail.tail).filter(_ != htail.head) }

i'm attempting create of software zoom image in winforms application. noticed answer similar issue stating achieved mousewheel using private void image_mousewheel(object sender, mousewheeleventargs e) { var st = (scaletransform)image.rendertransform; double zoom = e.delta > 0 ? .2 : -.2; st.scalex += zoom; st.scaley += zoom; } that solution need, appears part of system.windows.media, doesn't seem part of winforms architecture. does know of similar option winforms end resembling functionality? google searches haven't turned :( thanks! you might want graphics.scaletransform . idea of arbitrary transformations part of rendering process isn't all-pervasive in windows forms, transform 1 image image via graphics , believe.

i aware can control documents crawler/spider can access robots.txt, meta tags, link attributes , on. but in special case want portion of document being ignored. portion can not exist in iframe, "normal" content. <noscript> blocks amazing, mark partial content "don't index this, please." first, thought using document.write() write out parts, learned assumption "spiders not execute javascript" seems wrong. i thinking serving different version of page when detect crawler, not accurate, right? also, can not put content on image. are there tricks avoid getting specific part of document (not specific words spread around document) indexed? [edit] know "if user agent in list of robots", don't idea. possibly there more agnostic approach. part suppressed contains dynamic content , whatever doing, has work "old" browsers ie6 :\ only difference between static content , dynamic content extension of file incl...

is dangerous returning pointer out of std::map::find data , using opposed getting copy of data? currently, pointer entry in map , pass function display data. i'm concerned items moving causing pointer become invalid. legit concern? here sample function: mystruct* structmanagementclass::getstructptr(int structid) { std::map<int, mystruct>::iterator foundstruct; foundstruct= mystructlist.find(structid); if (foundstruct== mystructlist.end()) { mystruct newstruct; memset(&newstruct, 0, sizeof(mystruct)); mystructlist.structid= structid; mystructlist.insert(pair<int, mystruct>(structid, newstruct)); foundstruct= mystructlist.find(structid); } return (mystruct*) &foundstruct->second; } it undoubtedly more typical return iterator pointer, though makes little difference. as far remaining valid goes: map iterator remains valid until/unless item refers removed/erased map. when ins...

at moment key event generated in gui passed through several classes , given class running in separate thread. thread waiting key event , when 1 received variable further class chain altered (see diagram). during debug variable not changing. the class thread accessing of course in own thread being called gui has led me think problem concurrency. is there way solve perhaps using atomic integers or locks? i've seen few examples using synchronized functions can't them work don't explain requirements of classes. (by mean give code synchronization not explain how make class "synchronisable"). here code thread in class e, can the thread's object reference set class above receives reference of class class above etc. private processor processor; public void run() { while (true) { if (keyevent != null) { keyevent = null; processor.i = 4; } } } public void setprocesso...
