apperently I still was a dll short (copied all of them and now it works)

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

I think you not understand me ,
for example :
I wants to send command in my program
to click a button in another program (as word ).
thanks

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

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

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
|
|
|
|

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

Dear All,
We are developing a financial application in Visual Basic 6.0 with SQL Server 2000 at the back end database and Crystal Reports as reporting tool,I am facing some problems with Visual Basic 6.0,my questions are as follows:
1) We are using MSHFlexGrid to display data , my question is that can we make the cells of MSHFlexGrid editable, I mean that user can enter or edit the data displayed in the datagrid,is this possible in Visual Basic 6.0,are there any controls for it and if this is not possible than how can we achieve this?
2) Can I insert controls in the datagrid(MSHFlexGrid), like if I want to display check boxes in the first of grid that when that when the user check the check box the entire row is selected,if it is not possible than how can we achieve this.
3) Is it possible to make the columns "Sortable", I mean if I click at the top of the column than the entire column is sorted, if this is not possible in Visual Basic 6.0 than how can we add this feature.
I would be waiting for your replies and suggestions so please reply as soon as possible.
Regards,
Taqi Raza.

hi,
1. yes, you can edit the data from your flex grid.
2. im not sure for flex grid but in MSHFlexGrid it is possible to put a check box in a row.
3. also im not sure in flex grid if it is possible but in MSHFlexGrid1 it is possible to do that.
Don't block the drive way of all the newbies in programming.

You can just use network paths the same as any file paths. What are you hoping to achieve over your LAN ?

Did you read MSDN ? Picturebox does not take a path, it takes an image. So, you need to create one, as in
picturebox.Image = new Image(path)
