excel - Using variables instead of column names or numbers -

-

i'm trying draw chart in excel , here code 

activesheet.shapes.addchart.select activechart.setsourcedata source:=range("'resulthl'!$e:$e") activechart.charttype = xlxyscattersmoothnomarkers activechart.seriescollection.newseries activechart.seriescollection(2).values = "='resulthl'!$cb$1:$cb$2520"

this working fine i'd t know whether can assign column names or numbers variables , use in above code.

in line 2--> activechart.setsourcedata source:=range("'resulthl'!$e:$e") need assign e variable , use

also in line 5, need use integer variable instead of 2520

how do that?

i find it's easier use cells and/or resize properties bogged down in messy string concatenation business.

example:

dim rngapples range dim shtresults worksheet dim lngmaxrow long  shtresults = worksheets("sheet1")  ' define range want plot lngmaxrow = 2520 rngapples = shtresults.range("cb1").resize(lngmaxrow, 1)  activechart.seriescollection(2).values = rngapples

alternatively, can define range follows:

lngcolnum = 56 ' or whatever cb lngmaxrow = 2520 rngapples = shtresults.range(cells(1, lngcolnum), cells(lngmaxrow, lngcolnum))

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...
