I would like to be able to access one appdomain from another on the same machine. This used to be easy in vb6 to access COM objects as the GetObject() method could be used.

I know it is possible to do this using remoting, however this seems a bit of an overkill as both programs are running on the same machine. More importantly when I use remoting it triggers off alerts from my firewall. As I want my application to be easy to use I feel this will confuse some users and does not appear very professional.

Anyone got any suggestions?

Many Thanks

Hi All,

Could you please help me in the below problem?

I am getting the exception 'StackOverFlow' while executing the below code.

Dim nodeIter As XPathNodeIterator<br />
nodeIter = thisXMLNav.Select(thisXPQuery)

I am using .net framework 1.0. But in some other machines I am not finding this exception.

Thanks in Advance.

i don't know what thisXMLNav.Select() is doing, but in general, stack overflow exceptions are thrown when a function calls itself, in an "infinite loop", until the stack have not enough memory to perform another function call...

is it a function of your own, or does it com from a library ?

treeview node click event question

Hello, I have a doubt:

I have a vb.net treeview, and I want that when I select one node, if I press the child of this node, then show a msgbox.

How I can capture the click event for the child of the node.

Thanks

Surely you can just get the click event of the treeview, record the id of the node clicked. Then when they click the next node check if the parent is the same as the one you recorded before then hey presto it's the child and then you can msgbox gallore

Hope that makes sense and fits the problem.

Hi all professional friends, anybody know how to code a "Combobox" in the some column of listview? I don't want to use with dataset. Because I need to add some item into combobox myself and let customer select the combobox item in the listview.

Dim oCom As New ComboBox

With ListView1
.Controls.Add(oCom)
End With

Worked for me!

I remember that in vb6 there was a way to get where a form close was called from (ie. clicked x, computer shut down etc.) Is there a way to get this in .net.

How on earth would you get the fact that the form had been shut down by the computer shutting down ?

A modal form has a DialogResult, which is some help, but not as much as you're hoping, I don't think.

The form QueryUnload has a variable called UnloadMode As Integer that could be used to tell you where the unload was called..check it out. It seems they removed this in .Net, bummerr.

You can do this by overriding the wndproc method and checking for WM_QUERYENDSESSION

Windows sends a message to all open applications on the event of a shutdown.

Yeah, I know that. But I read the question to be, how to tell how something WAS shut down, not how to tell that something is BEING shut down. So, a child dialog is closed, and the parent works out why.

I have started a project to do it. I am overriding WndProc and catching some of the messages. I am having trouble figuring out which ones though. I have this so far.

MyBase.WndProc(m)<br />
<br />
        Select Case m.Msg<br />
            Case Is = Win32.WindowsMessages.WM_QUERYENDSESSION<br />
                f = New UnloadModeEventArgs(ECloseMode.AppWindows, False)<br />
            Case Is = Win32.WindowsMessages.WM_SYSCOMMAND<br />
                If m.WParam.ToInt32 = Win32.WindowsMessages.SC_CLOSE Then<br />
                    f = New UnloadModeEventArgs(ECloseMode.FormControlMenu, False)<br />
                End If<br />
End Select

Can someone please tell me how the run method can recognize a path with spaces? THis should be simple but I'm driving myself crazy trying to get this to work. Can someone please help?

in vbscript...

Option Explicit

InstallClearCaseClient

Function InstallClearCaseClient ()
Dim objApp
Set objApp = CreateObject("WScript.Shell")
objApp.Run cmd /K CD P:\Information Technology\Configuration Management\CC_Client_2275_install &setup.exe client_2275sitedefs.dat
Wscript.Quit

Set objApp = nothing
End Function '

Any command line path that has spaces in it must be enclosed in double quotes. Otherwise, the path will be translated into multiple arguments.

objApp.Run "cmd /K CD ""P:\Information Technology\Configuration Management\..."" whatever else you want on the commandline"
