Java & Multiline Batch Files -

-

i try run batch file in java, file performed not completely. code like:

runtime.getruntime().exec("cmd /c call "+path);

when try run manually, without java, batch works correct.

batch file contains next code:

cd c:\downloads\ if not exist documents mkdir documents move *.odt documents move *.doc documents if not exist archives mkdir archives move *.tar archives move *.gz archives if not exist music mkdir music move *.mp3 music

java complete batch fifth line. has faced this?

hm, batch, stoped again here. , java code: link. if add somename.ogg downloads folder, script goes next line. folders (archives, documents etc) exists, , downloads folder doesn't contain *.zip, *.tar, *.docx, *pdf files, these lines passed without problems. why stoped precisely @ ogg-line?

i think problem there bug in batch script. msdn documentation if command states this:

you cannot use if command test directly directory, null (nul) device exist in every directory. result, can test null device determine whether directory exists. following example tests existence of directory:

if exist c:\mydir\nul goto process

now way using (if not exist directory mkdir directory) succeed if directory doesn't exist ... attempt create directory second time if exist. ooops ...

now, java application read , printed out contents of error stream process, you'd see error message telling archives directory existed. ignoring output asking trouble, imo.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
