Hi,
if you ask for processes, you get processes.
a process has zero, one, or more windows; some of them may be open and visible.
If you want windows, ask for windows; that would take P/Invoke and the functions
EnumWindows and even EnumChildWindows in user32.dll

Hi,
if you never used P/Invoke before, EnumWindows is not good for a first experience !
But if you did, search the documentation; look in MSDN, CodeProject and Google.
also www.pinvoke.net may help you.

Some operation depend on the system date ..
and if user changed it ,,, it's a disadvantage ...
then how can I prevent it ?
jooooo

you can poll it to see if it has been changed. If you can write code that sets the time, then you can change it back. I am certain you cannot stop a user changing it.

Like Christian said, you cannot really prevent the user from changing the time on his/her machine, however, if your app requires some operation that is sensitive to time change, you might want to consider getting the time from an off machine source such as another machine on the network or a time server...

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

Thanks man , i got a Solution, the sql parameter variable in the adapter was not the same as the on i passed in the Parameter function. but now its working
Thanks

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

to click a button in another program (as word ).

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
