As I compare the DSO with the DSO para, it seems doesn't compare both data at all. I have been converting the DSO as double first between comparing it as if i compare with string it doesn't work.
Dim dso1 As Label = CType(e.Item.FindControl("dso1"), Label)
If Not IsNothing(dso1) Then
dso1.Text = e.Item.DataItem("DSO").ToString

I have a text reader and I wish to parse the readline string data in double.[code]...
I do not necessarily wish to define the split to interpret double space as separator as I do not know whether this is always the case. I would rather like to tell the program that there are three double format numbers -> go and parse.

I have a problem that seems trivial. In an argument to an activity I need to supply a path.
This is done by this code:
String.Format("a
-bd -y -tzip {0} {1}* -r",
Path.Combine(BinariesDirectory,
"output.zip"),
BinariesDirectory)
However, the directories parameters contain spaces so they have to have quotes around them. I tried with single quote ' that works fine to put in the string, but the command shell executing the command ignores these. So it has to be double quote "
I have tried all methods I have fount on the Internet, for example to have a backslash before the double quote and to have three double quotes, but nothing seems to work. I get a compiler error as below.
Error 4 Compiler error(s) encountered processing expression "String.Format("a -bd -y -tzip "{0}" '{1}*' -r", Path.Combine(BinariesDirectory, "output.zip"), BinariesDirectory)".Comma, ')', or a valid expression continuation expected.

Why is it generating on on the client's computer and not mine?

This is wrong because I'm not escaping it properly:

This is wrong because there is not blank character character (to my knowledge):
