Yeah, the easiest way to validate is to only let the user type in something that is valid  I can't recall if it was apparent if this was a web or windows UI though. I know it can be done with a web UI, but I tend to shun Jscript as I fear browser issues.

Just a thought, what if we create a custom textbox which allow you to type only numbers and inserts "-" at proper places automaitcally

I know generally how to raise and detect/handle events in my own programs, but how does one detect system events? I can't imagine there aren't events raised when someone selects a start menu item, much less something like a system error or a new usb device being inserted.
anyone have a few hints where to start looking for things like this? and what about making my programs raise system-wide events? are all events system-wide(if they are public that is)? thanks to anyone with this info.

There are code samples for HID/USB events around. A start menu item, I'm not so sure of, but you can write global hooks for global events, in C++ at least.

Lot of stuff all together.
There are classes in the .NET Framework you can use to get some system events (i.e. FileSystemWatcher, ...)
Others, like USB or PCMCIA insertion have some sample code around here (as stated in previous reply)
I don't believe a there's a system event for a start menu selection. Only way could be to get all the system msg but I guess you need to use something different than VB.NET (I may be wrong).
To generate system event is a slightly diffent, and depends on what do you mean. Create "fake" events? Notify every task of something (or only some "listening" tasks?)?

Is it possible to develop a user control or windows form that can be embeded in an html document. The html document will not necessarily be served by a web server but may be located on the local machine.
If so, is it possible to have this control/windows form automatically deployed using click once?
I'm essentially trying to mimic an ActiveX control being embeded into an html document.
Thanks

Hi Everybody
I'd like to know if there's a way to put a reference on a Visual Basic project to a OpenOffice.org program to run it and control it from my Visual Basic Application. I know that we can do this with Microsoft Office applications, in fact I'm using Excel in my project but I'd like to try something different as OpenOffice Calc for example. I searched in the internet but I didn't find anything  If you know something about, then please let me know.
Thanks in advance.;)

To open and run it you just need a shell command from VB ... to control it is more OO related (and dependant to). So I guess you'll get more info if you ask it on its website!

Hello
How I can show TV with Managed DirectX 9 ?
Can you showme a sample ? please
Thanks

This is such an amazing question - how would a software SDK get a TV signal unless you have the hardware to recieve/decode it ?
The answer is no, you need a TV card to recieve a TV signal.

Hi,
Im trying to get computer information of all PC's on a domain.
I got the following code from Microsoft:
Dim TheDomain As IADsDomain
Dim Computer As IADsComputer
Dim strDomain As String
Dim iMousePointer As Integer
'Accept the Domain name
strDomain = InputBox("Domain Name: ")
'Use the WinNT Directory Services
strDomain = "WinNT://" & strDomain
'Create the Domain object
Set TheDomain = GetObject(strDomain)
'Search for Computers in the Domain
TheDomain.Filter = Array("Computer")
For Each Computer In TheDomain
List1.AddItem Computer.Name
Next Computer
My problem is that this is VB6 code and I need a working dotNet equivalent.
All works fine up untill the Array("Computer") function, VB .NET doesn't support this function.
Can anyone help me with an alternative way to build this collection so that I can use is in the "For Each" loop?
I'm guessing Active Directories will be the answer but I cant seem to get it right. 
Thanx!

I got it right afterall.
I wrote the code in VB6 and built it as a DLL.
Then referenced the DLL in VB .Net, works like a bomb!

i have to set timer in my windows application.
if date of set_timer column in database is equal to system date time then a beep should be generated.
i am unable to write exect code for retrieving that perticular date where set_timer= system.datetime.now()
i had write sql query in adapter, all were failed to get data from data set.
select * from case_details where (set_timer= dt)
select * from case_details where (set_timer= 'dt')
select * from case_details where (set_timer= '&dt&')
where dt was declared as
dim dt as system.datetime
dt= datetime.now()
i had also use convert function
as
select * from case_details where (set_timer= CONVERT(DATETIME,dt,102))
it is also not woking plz help me.

A datetime runs right down to the millisecond. You need to make your query so that it has less granularity, by either stripping info from all datetimes you store ( for example, set all milliseconds to zero ), or by using a range in your query.

I have a class library written in C#. I have use it using "Add Reference" in a VB.NET windows application. Is there any way to lock the class library(dll) in such a way that no further "Add Reference" is possible ? Basically I want to prevent the reusability of the dll file for any other application except the VB.NET application, I told above. Is there any way to do such things?
Thank you in advance.

Well, if you created a DLL meanted to be incorporated somewhere else ... there's no way to lock it. Different if you have a class inside your assembly, than you can use the private/friend/protected/public clause to set visibility/usability.
If you're concerned about blocking third party uses ... well then a way of doing it is to put a "secret code" in the constructor that work as an enabler. Than only who knows that code (you) can "activate" the class.
