is solved (partially)
apperently I still was a dll short (copied all of them and now it works)
now I still have to search for the correct dll but that's just trial and error I guess

hi i have datagrid i need to search. i wrote the following code

     SqlDataAdapter2.SelectCommand.Parameters("Lis_key").Value = txtnumkey.Text
        SqlDataAdapter2.Fill(DataSet21)
        If DataSet21.Tables("Property_Mass").Rows.Count = 0 Then
            MessageBox.Show("Township not Found")
End If

when i run the code and search with a correct Lis_key field, it gives me the Following Error.

An unhandled exception of type 'System.IndexOutOfRangeException' occurred in system.data.dll

Additional information: An SqlParameter with ParameterName 'Lis_key' is not contained by this SqlParameterCollection.

What is the Problem?
it points to this line

<br />
SqlDataAdapter2.SelectCommand.Parameters("Lis_key").Value = txtnumkey.Text<br />

Thanks

my first guess would be that you didn't contain an specific sqlparameter in you're sql string

try adding on like this

dim sqlparam as new sqlparameter("@lis_key",value)
sqldataadapter2.parameters.add(sqlparam) 'not entirly shure about this one but it's something like it

hope this helps

You can just invoke the button's OnClick event handlers. Not sure what your users would think of your app if all the sudden it took over itself Suspicious | :suss:

No, how about you be a bit more clear. Look back at your original post and you don't make it sound like you want to control another program outside your app Hmmm | :|

VB.Net add child node to treeview control

It's possible, but notoriously unreliable. It's not easy to do and not for the begginer to tackle.

This involves finding the correct window (all controls are relly windows), getting it's window handle, and sending the proper window messages to it. If you don't understand how Windows windowing system works and the API calls to manipulate it, you're going to find this project just about impossible to do.

Hi dudes,

In VB6 we could add a child node to a treeview control by specifying a key for an existing node, then a relationship then the new node to be added to the tree. How can i do something like that in vb.net, given that from the add method of the .net treeview there isn't even one thats requiring the parent key and relationship?

Thanks spans in advance Confused | :confused:

dim tnode as new treenode("text") ' is the main node
treeview.nodes.add(tnode)

dim tsubnode as new treenode("text") ' is the subnode
tnode.nodes.add(tsubnode)

this should give you 1 main node with 1 subnode

hope this helps

Thanks TDDragon for your reply,

The thing is I do not know the depth of the tree before-hand and I am adding the child nodes recursively, its a something like an explorer program. So i would need to add whatever child node to any parent whose key i know Hmmm | :|

if you go tru it parent node by parent node you can do it like folowing:

dim tnode as treenode()
dim subnode as treenode()

if "check the node you need to add" = "parent node" then
tnode = new treenode("text")
treeview.nodes.add(tnode)
else
subnode = new treenode("text")
tnode.nodes.add(subnode)
end if

remember this will only work if you make you'r treeview parentnode by parentnode

if not (you need to add a node to parentnode1 while you already created parentnode3) then maybe this might be some help

'first create alle parent nodes and give the tag property a key value
'then iterate true you're parent nodes and where node.tag = key add a subnode

for each t as treenode in treeview.nodes
if t.tag = key then
dim subnode as new treenode("text")
t.nodes.add(subnode)
end if
loop

this way will take more time so if possible I would recomend the first way

hope this helps
