Hello
The code is copied from MSDN here is the link:

Knowledge Base:
How to populate a treeview control with XML data in Visual C# 2005
or in visual C# .NET


ms-help://MS.VSCC.v80/MS.MSDN.vAug06.en/enu_kbnetframeworkkb/netframeworkkb/317597.htm

Running on a Dell Inspiron 9400 dualcore, with 2GB Ram
Intel CPU T2400 @1.83GHz

Using VisualStudio 2005 and C#
The XML File is 158kb and has the folowing structure:
<Root>
<sz> x="1.1" y=1.1</sz>
<mx> x="1" y=1</mx>
<dm>
<dc x="1" y="1"/>
<op x="1.1" y="1.1"/>
<fp x="1.1" y="1.1"/>
<fs x="1.1" y="1.1"/>
<fr x="1.1"/>
<dv>
<bpc x="1"/>
<op x="1.1" y="1.1"/>
<fp x="1.1" y="1.1"/>
<fs x="1.1" y="1.1"/>
<fr x="1.1"/>
<bp>
<op x="1.1" y="1.1"/>
<fp x="1.1" y="1.1"/>
<fs x="1.1" y="1.1"/>
<fr x="1.1"/>
<Req x="1">
<st>1</st>
</bp>
</dv>
</dm>
</Root>
This is only the structure, the names are 10..15char's long
The attributes "1.0" are floats
The "1" are integer values

Each dm contains 64 dv's
Each dv contains one bp
There are 4 dm's and 64 dv's in one dm: 256 dv's and 256 bp's

Loading the XML DOM using about 40ms ... 500ms
Loading the tree using about 55..58s

regards remo

Mhh... interesting.
Out of curiosity, why do you write slow code?

Cant believe it:
Loading an XML document (150kb) in a treeview using .net 2.0 using
2.0 seconds!!!
That is unusable!!!
Loading the same document in Iexplore, it needs 1/100 of a second
That could not be .net
That is incredible, and non usable.
What in the hell do ms wasting the time...

regards remo
