How can i use a pc's existing hardware for analog to digital conversion?

There are no A/D converters in a PC that you can use with an external source.

Can you be more specific? What are you wanting to know? Your question is far too general!

the object myclass has events defined within. when certain actions are done within that class you'll see a line that says for example
"raiseevent click()" in the object that has the line withevents. you will have a routine:
private sub ObjectJ_Click(sender as object, e as system.eventargs) handles objectj.click
'do something here
end sub

Can i implement the map objects in vb.net 2005 window Applications

You're going to have to explain what you mean by "map objects" in order for anyone to answer this question.

If you have Google's toolbar intalled, you'll notice that in Internet Explorer 7 the right-click context menu shows their "G" favicon/icon next to their context menu insertion. Does anyone know how to do this? Many new applications are doing this. Primarily, I assume, because it helps their text insertions stand out from the increasing number of apps which install commands to the context menu.
Also would like to know how to add separators above & below context items.
Any help would be most appreciated.

This will create the registry key in the correct location, However as far as launching your application using the context menu item goes, i cannot help you:
Dim regkey As RegistryKey 'imports microsoft.win32<br />
regkey = Registry.CurrentUser.OpenSubKey("SOFTWARE\MICROSOFT\INTERNET EXPLORER\MENUEXT", True)<br />
regkey.CreateSubKey("Test") 'You can put whatever you want here<br />
regkey.Close()<br />
<br />
regkey = Registry.CurrentUser.OpenSubKey("SOFTWARE\MICROSOFT\INTERNET EXPLORER\MENUEXT\TEST", True)<br />
regkey.SetValue("", "res://C:\test.txt", RegistryValueKind.String) 'you can change the path<br />
regkey.SetValue("Contexts", "3", RegistryValueKind.DWord)<br />
regkey.Close()
Note: Your path will need to be the install directory of the application.

I have a little confusion in serialization.
I know serialization is saving an object and the current values of all it's
properties using serialization.
I mean what is the use of storing the object .What is the advantage of serialization.
Please tell me.
Thanks and regards

serialization allows you to convert an object into a string(xml) and transfer that object to another source(computer/server) via webservice or tcp.
an example of why could save one...you could write something to check a timestamp and if it's the same why go through the hassle(queries, transactions) again of populating the object when you could just read it from a file.

What would be the point of adding File -> Save support to your apps without it? Serialization isn't just for sending objects between computers.

I know you can use serialization to save some of the settings/properties of some controls such as combo-boxes etc ... but can you use it to save the settings of an ActiveX/ocx control?
If you can .. how do you go about it?

Hey guys,
I'm making an IRC client and decided to muck around with the scripting GUI. I'm basing it on Visual Studio 2005/Orcas' interface, with the line numbers and the auto-complete style. I decided I would like to add the collapsible region type thing to it, for each function and custom areas. I tried looking at Sharpdevelop, as it has the same thing, though it's a little complicated for my liking.
I also took a look at Fireball (I think that's the name), another editor which has regions in it, though a lot is in Spanish and somewhat confusing, though the regions are less buggy than on Sharpdevelop.
What I was thinking, is that, store the text in memory and then draw it on the textarea, though I think I'd need to set the text on the control so it can handle the cut, copy, paste, navigation, etc. When I do that, it doesn't draw the text at all, only what the RTB.Text equals.
If someone could please point me in the right direction or if they have looked through the Sharpdevelop and/or Fireball code (as it's C# and I don't know that all too well) and help, I would greatly appreciate it.
Regards,
Daniel Wallace

Asking the question again won't change the answer[^].
You really do not need a DSN. Building a DSN is actually far more complicated than just building a connection string to your Access database.

No-one can answer that. Download the Direct X SDK, it is full of samples. You need it, in any case.

You need to create new bitmaps for each section, and then copy the sections into them. Finally, don't use picture boxes, draw them in your paint event. Picture boxes do not scale well to what you want to do.

Hello,
[VS 2005]
I have a problem that i want to install on a user computer. After the installation the program will check to see if the database is update. If not, the it will run some sql script file to update the database.
I have the sql script file, but not sure how to get the program to look for the script file to execute it on the server, if the database not up to date. The script file should be part of the installation.
Anyone have any ideas or can point me in the right direction.
Many thanks,
Steve

Why would you want to install "a problem"??

That depends on the database engine in question. There are various command line tools that come with various engines to do this. I think the one for SQL Server is OSQL. You just give it the path of the script to run and some logon information and it'll run the script.
