So in this case, the watcher instance's lifespan is until either the program terminates or I explicitly unregistered the event handler at some point later in the code and I guess that would need to be in the specified callback method itself since I don't actually have a way to get to that watcher instance once the setup method is done.
Thanks for the clarification on this.

Correct. Generally if you need to unregister an event handler you need to save the needed instance information in class variables.

AFAIK you can't. Take a look at the DataGrid instead.

how can i open(visualize) a System.Windows.Forms.MenuItem of System.Windows.Forms.MainMenu by code?
jaye

|
|
|
|
if this menuItem has other menuItems under it you use the following statment
<br />
menuItem1.ShowDropDown();<br />
if it doesn't have you show use the above statment on its parent menu item

It can't. The ShowDropDown method is member of the ToolStripMenuItem class that is new in .NET Framework 2.0.
I think the classes in Framework 1.1 provide no support for what you're trying to achieve, so you're somehow at a loss.

I suggest you try MenuItem.PerformClick()

that's right, but if you do this on the parent menuItem it will do what you wish
cz the click event of the parent menu item is to open its drop down items.
for example if your have a File menu item and under it New.
if you like to view nuew you write:
fileMenuItem.PerformClick();

Did you tested this? I've tried and it doesn't work. Also the PerformSelect method doesn't show the menu.

No need to apologize. I was just curious if it may work on other computers.

Maybe one could disassemble the ToolStripMenuItem and see what they are doing inside the ShowDropDown method. Or use Windows API to really simulate a mouse click on the menu item.

I need to develop an application, in C#.Net . I have two Touch panles connected to the system. My program have display different frames in different touch panels. Have anybody worked in such application? If so please tell me how to design it? How we can tell windows GDI to distinguish frames for different display?
Thanks
Bil

When you have a multi-monitor setup the two monitors are seen as one continuous area. e.g. You have two monitors of 1024x768 each. The screen will be 2048 pixels wide. 0-1023 is on one monitor and 1024-2047 is on the other. So, telling GDI which monitor to display something on is just a matter of drawing at the appropriate coordinates.

Thanks Colin for your reply.
Your answer gives me some idea what to do.
I have some more questions to ask you.
Do we need to tell the windows that we are using 2 monitors. If so where we need to configure it?
If I am creating an application I have to create in such a way that it will cover up the the 2 monitors? Do c# allows to do so?
Is there any way we can configure GDI?
Thanks and Regards
Binil

Hi,
I once had a two-monitor system, and did some .NET work on it.
I remember you could move the relative positions of the monitors, and you could set both
monitors to different settings (e.g. bits per pixel).
So when shifted by 384 for instance, having two 1024*768 monitors could result in a desktop 2048 wide and 1152 high, with two rectangles of 1024*384 invisible.
You can extend a form to use whole or part of both monitors, simply drag as usual.
You dont have to tell GDI, just use the coordinates of this "extended desktop".
I think I also recall a form will maximize on the monitor that shows its top lefthand corner.
One of the monitors is the "primary monitor", you can choose which one.
The primary monitor is the one that displays boot progress, and shows the task bar.
FYI: programs such as screensavers most often ignore all but the primary monitor;
they should however handle all monitors, either with one big picture, or with multiple
pictures.
Hope this helps,
Luc Pattyn
