Now that I plan to upgrade to vb.net, I find that these COMs no longer works. Is there any way to make them work, short of looking for updated versions of these COMs( some of these third party companies are no longer operational) Thanx Notorious SMC The difference between the almost-right word & the right word is a really large matter - it's the difference between the lightning bug and the Lightning Mark Twain Get your facts first, and then you can distort them as much as you please Mark Twain Re: Using old com objects Jonathan [Darka]12-Dec-02 22:08 Jonathan [Darka] 12-Dec-02 22:08  Hi, yes you can reuse them,you need to create a COM runtime wrapper for them which can then be used as a proxy to your original COM objects. Use the "tlbimp.exe" tool which comes with Visual Studio .NET like this, tlbimp oldcom.dll /out:oldcom.asm.dll then you add a reference to the oldcom.asm.dll file to your .NET app. regards, DarkAngel Re: Using old com objects Nick Seng12-Dec-02 22:51 Nick Seng 12-Dec-02 22:51  Thanx man! you're a life saver!

The problem is that the selected node in the treeview control doesn't seem to change when I'm hovering over them with the item dragged.

I have some componente written in VB.Net that is called by ASP pages. All of them works fine except for one that gives me the "class doesn't support automation" error message. The only help that I've got was "try to contact the application vendor"... Running it interactively, I have another error message that I'm trying to work around ("The root transaction wanted to commit, but transaction aborted"), but this is a ContextUtil problem. All the components have the same imports and inherits clauses and same properties in the packages. Any clue? Thanks in advance, Molina.

RHYS10-Dec-02 0:22 RHYS 10-Dec-02 0:22  Does anyone know a way to capture a process? What I need to do is when a link is executed capture the link from the process. If possible, to then stop the process before it is fully executed. I am running a utility which detects for links to other documents ete..I am using this utility to detect links in a certain program which cannot be found programatically through VBA( believe me i've tried! ). So the only other way I can think of is to execute the link, capture the process hopefully with the link and stop it before it fully executes. Any ideas???? Kind Regards, Rhys.

Re: double clicking on list view item or row in report view......... RHYS9-Dec-02 21:29 RHYS 9-Dec-02 21:29  Hi, Place the listbox control on your form and give it a name. Then double click the listbox and you will be taken into the code window. At the top of the events window you have 2 drop down boxes; the right hand list is the events list. If you click on this list you will see that below "Click" is "DblClick". You now have the double click event for your list box. With regards to opening a form there are numerous ways, this simplist being "Form1.Show". You should do a bit of reading of books as there are many ways of doing this depending on your purpose....
