Thanks for your reply Luc.
My requirement is little bit different. I have two touch panles in which I need to show two different frames. User can control the system from both the touch panels.
So an action in a touch panel is expected to reflect on the same touch panel only. It means there are logicaly 2 users using a same application.
Is there any way to design such a user interface program.
Thanks

Well, I guess there are many possibilities:
1. run two apps, each using part of the extended desktop, each part corresponding to
one touch panel.
2.run a single app that shows two modeless forms, one on each tp
3.run a single app that has a single borderless form encompassing both tp, and two
Panels, one for each tp.
The third one seems the easiest, whatever you choose you must dispatch input events
to the right app/form/panel, but that is not a GDI issue. GDI is taking care of the
graphical output.
I am not familiar with the touch side of touch panels, I expect it should behave much
like a mouse, with mouse down events etc.
I would go for 3. and create a TouchPanel class that extends from Panel and holds
whatever specific functionality you want to give it, including the touch event stuff.
If you know how to handle one touchpanel, the above should be sufficient to deal
with two of them.

Thanks Luc.
That gives me better idea. Do we need any extra configuration in the GDI or display level , so that the display will be properly taken care and routed to different monitors. Do we need to write a display driver for it? Does windos XP embedded supports it?
Thanks

Hi,
I dont know the answers to those questions; I am unfamiliar with WinXP embedded.
Two thoughts:
- the people selling you the touchpanels should take care of whatever is required to
interface it properly to the Windows version you choose; and it must be in such a way
that it works under GDI+. (Remark: GDI+ is technology outside .NET, it started of as GDI,
.NET simply offers a wrapper on top of it).
If they dont offer this, it is the wrong vendor !
- you would also need confirmation that the multi-monitor behavior that I described
before (and applied to WinXP) also applies to your Windows version. This is primarily
a Windows matter, but then there is a posibility your touchpanel's driver might be incapable
of handling two panels or of running twice in parallel.

Hi,
I wish to have the format of the date saved into my database as a short date format.
The MS Access DB field is configured for the datetime format.
Thanks,

You can't change the access database, or you don't want to ? How does this relate to the datetimepicker ?

The text and value fields are bound to the database and are being saved to the db in the long format ie including the time.
I just don't want the time portion saved in the database field.

I think this is the only way :-
this.dtpMailInDateRcd.Value = this.dtpMailInDateRcd.Value.Date;<br />
this.dtpMailInDate.Value = this.dtpMailInDate.Value.Date;<br />
this.dtpMailInRepliedDate.Value = this.dtpMailInRepliedDate.Value.Date;
before I save the data.

Hi,
I dont think even that might be a solution, since the value that you pass from your front-end is first parsed to the date format at the time of saving in the database. Hence, if the date format is "LONG" in your Access Database, then in that case, it will add time to the value passed from the front-end.
However, one solution could be that you change the format of the date (in the Design View) of the table to "mm/dd/yyyy" in the Format textBox in the General Tab and from the front -end you pass the value as
suggested by you in your previous thread.
this.dtpMailInDateRcd.Value = this.dtpMailInDateRcd.Value.Date;
This probably might help.
Thanking you in Advance

HI all,i had a query regarding Exception Handling.consider there r 30 webpages,which doesnt consists any type of Exception Handling techniques or code.as it is maintenance and enhancement project,how can i trace the errors and how to make it follow coding standards.
pls help me.
Thanks in advance
Bobby

A good first step would be to write a base page class, which handles and logs unhandled exceptions, and make all pages derive from it. From there, you need to decide where exception handling is needed for specific cases, and add it.
Putting all code in try/catch(Exception) blocks is bad practice, you should add exception handling only for specific exceptions that you can anticipate and recover from.

HI Graus
Thanks for ur fast reply.can u tell me some more detail how it handles and logs the exceptions.
pls spare me some little time
thanq

Any code I write, at the top level, will just catch it, write it out to a log file ( the exception and the stack trace ), and then show an error ( if it's winforms ) and gracefully exit. But, that's the last stop, the place where stuff I don't want to happen, gets recorded so I can have some lead on how to never let it happen again.

If user RegisterWindowMessage()in app A, than send this message, how to set hook to capture this message in app B?
|
|
|
|
|
A window can capture all messages it gets by overriding WndProc
for examples, just search "WndProc" on CodeProject.
Luc Pattyn
|
|
|
|
|
But in A app, there is no form, that means i can't override WndProc or DefWndProc,so what can i do?
thanks

This may be a good reason to give your app a window, possibly an invisible one !
Luc Pattyn
|
|
|
|

At the beginning, i want to use a invisible window,but i think it is a little uglily, so i passed this idea, At present most probably, this is a convenient and rapid way to solve the problem.
|
|
|
|
|
I am pretty sure it is the only way if you want to receive Windows Messages,
as was clear from your initial post. Many apps have a window just to be able to receive
such messages.

OK, i will try!

In the console you can set "BufferWidth", i.e. the size of the console buffer, to some other value than the default 80, and you will get horizontal scrolling.
