c# - Using a BizTalk orchestration to call .NET class library to read xml when there is new xml file in the directory -

-

i have set receive message , receive port monitor xml files. added expression shape execute .net class library using 

system.diagnostics.process.start         (@"c:\temp\xmlreader\xmlreader\bin\release\xmlreader.exe");

when deploy biztalk, new file gets received on receive location, file disappears , nothing happens. have other orchestration project receive , send port file disappears , not move send location

i not sure following logic. however, assuming have correctly set subscription between orchestration , message published receive port. by time orchestration activated, original file system xml gone forever. in fact gone once receive location enabled , consumes it. if trying manually read original xml file off file system, orchestration, not successful.

biztalk has pitfalls, when in doubt, stick incremental approach;

  1. create/enable receive port , location straight administration console (forget visualstudio now).
  2. pass in xml (or whatever)
  3. use management console see if message created , status is.

  4. create orchestration includes

    system.diagnostics.debug.writeline()

    statements, subscribe receive port.

  5. drop in message , use debugview see output writeline method calls.

c# - How to set Z index when using WPF DrawingContext? -

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...
