Hi Guys,
I am having a problem using a doNetObject in my script. Below is a function i have made to populate a listView with elements from an array. Thanks to Paul for the great listView tutorial from what it is based.
fn loadArrayFromXML theLV theArrayLV theArray newArrayValues=
(
theArray = newArrayValues
theArrayLV = #()
print theArray as string
for i = 1 to theArray.count do
(
ni = dotNetObject "system.windows.forms.listViewItem" theArray[i]
append theArrayLV ni
)
theLV.items.clear()
theLV.items.addRange theArrayLV
)
However, when i run the script i get a runtime error:
MAXScript MacroScript Error Exception: -- Runtime error: No constructor found which matched argument list: system.windows.forms.listViewItem
I am at a loss to explain why it is happening. I have a very similar function using the same object elsewhere in the script that works fine.
Any help would be appreciated.

does it give you a line where it says it’s throwing an error?
As your code is incomplete, I had to feed it some supposed values… got no error:
loadArrayFromXML listview_rollout.lv_objects undefined undefined #("one","two","three")
perhaps the values within the array that you pass as the newArrayValues parameter are invalid?
The array values i am passing are fine. I have even given the array new values in the function just to make sure, but i still get the same error. I get the error on this line:
ni = dotNetObject "system.windows.forms.listViewItem" theArray[i]
The message seems to indicate that no constructor exists in the loaded assembly but i find that hard to believe.
D’oh you are right! The values i am passing in the array ARN’T right. They should be strings and in the XML the test values i am using are integers >.<
I have been staring at it for hours… haha!
But i have a problem that the array i am saving in the xml files do not have quotation marks around the values in the array. And trying to do so makes the xml invalid. This is a problem. Does anyone know a good work around for this? I am using the execute command on the string to convert it into an array.
how about:
myString = "#(1, 2, 3, 4)"
myArray = filterstring myString "#(), "
-- returns #("1", "2", "3", "4")
Genius! Thank you so very much!
number values are easy to cast into different formats without having to use execute eg –
val = 1
1
val as string
"1"
val as integer
1
val as float
1.0
val as time
1f
you should be able to cast the numerical array into strings when you make your listviewitem –
ni = dotNetObject "system.windows.forms.listViewItem" (theArray[i] as string)
I will have a look at that too thanks
