c# - Set parent to wpf window -


earlier have used usercontrols show modal dialogs. decided implement wpf window. , have 1 problem. want set parent of window constructor of modaldialogwindow. know hwnd of parent window(can process name) , don't know how hwnd of child window(my modal dialog) const of it.

or need setparent window this

    var window = new modaldialogwindow(properties.resources.changelabelpartdialogtitle, changelabelpartdialog); setparent(childhwnd,parenthwnd);            window.showdialog();

but dont know how hwnd of window before showdialog() method

handle of parent window need. set parent dialog window can use system.windows.interop.windowinterophelper class shown in code below:

public partial class modaldialogwindow : window {     public modaldialogwindow(intptr parentwindowhandle)     {         initializecomponent();          var interop = new windowinterophelper(this);         interop.ensurehandle();         //         interop.owner = parentwindowhandle;     } }

rdbms - what exactly the undo information lives in oracle? -

some docs says, there "undo tablespaces" implies should create tablespace undo imformation. some docs says, there "undo segment" implies undo information lives in normal tablespaces , use of it's segment. so, undo information lives , organized? earlier releases of oracle database used rollback segments store undo. oracle9i introduced automatic undo management, simplifies undo space management eliminating complexities associated rollback segment management. oracle recommends (oracle 9i , on words) use undo tablespace (automatic undo management) manage undo rather rollback segments. when creating undo tablespace, these automatically created: n undo segments (based on sessions parameter value) named _syssmun$ owned public (usable ops configuration) not manually manageable

i'd have bats test created every file in directory, i'm not sure best way done is. approach below creates single test when there many files in directory. #!/usr/bin/env bats in $(ls) @test "testing $i" { pwd } done to extract ls output not batter solution go wrong on filenames spaces. you can below shopt -s nullglob file in /dir/* //test command on $file done shopt -u nullglob you can using find command also find /some/directory -maxdepth 1 -type f -exec cmd option {} \;

clojure - 'get' replacement that throws exception on not found? -

i'd access values in maps , records, throwing exception when key isn't present. here's i've tried. there better strategy? this doesn't work because throw evaluated every time: (defn get-or-throw-1 [rec key] (get rec key (throw (exception. "no value.")))) maybe there's simple method using macro? well, isn't it; has same problem first definition, if evaluation of throw happens later: (defmacro get-or-throw-2 [rec key] `(get ~rec ~key (throw (exception. "no value.")))) this 1 works letting get return value (in theory) never generated other way: (defn get-or-throw-3 [rec key] (let [not-found-thing :i_would_never_name_some_thing_this_021138465079313 value (get rec key not-found-thing)] (if (= value not-found-thing) (throw (exception. "no value.")) value))) i don't having guess keywords or symbols never occur through other processes. (i use gensym generate special value of...
