Code below works fine for me. "Size" will be returned ONLY if there is a DVD in the slot.
ManagementObjectSearcher o = new ManagementObjectSearcher("select * from win32_cdromdrive");
foreach (ManagementObject obj in o.Get()) {
string s = obj.GetText(TextFormat.Mof);
}
Hope this helps.

You can do it by using FileSystemObject
Dim _oFSO = CreateObject("Scripting.FileSystemObject")
Dim _oDrive = _oFSO.GetDrive("G:")
MessageBox.Show(_oDrive.TotalSize)

No, this returns the used size of the cd and not the total capacity. By total capacity I mean for a CD ~ 700 MB, and for a DVD ~4.7 GB etc. I have to know this because I have to calculate for how many percent a cd is used. (Used space / Total Capacity) * 100. Any other ideas, maybe? 
Thanks for your reply, though!

Just a thought, and post back please if you succeed because I am interested.
Check this solution Get Total Free Space Drive[^]
I have Vista and Nero with InCD Installed and I had tried over a dozen of code to get the capacity of the CD/DVD and I am getting an error.
Is that your case also?

Nope, this example did not work aswell, because a CD never has any free space. The maximumsize is simply the size of the data burnt on the cd/dvd.. And yes, this is my case aswell. I can't find ANY solution on how to determine the real capacity of a DVD or CD nor can I find a solution on how to see whether the inserted medium is a DVD or CD. I'm totally stuck.. 
Cheers,

I would like to show a sample of a Font from an uninstalled Font file.

Hi,
I haven't used it yet but AFAIK .NET provides a PrivateFontCollection class for such purposes.

Every human being on this planet (with even the tiniest brain) knows that AFAIK means "As Far As I Know". You see, when answering to replies like this, it discourages people to ever post again, because all they'll get is a bunch of crap. Please reconsider before you post like this. Your reply to the question was nice, though.

Hi Zaegra,
that's what I hate in thouse forums, the respectless way of talking to each other. I did not know the term AFAIK and did, by missreding it as AFAIK.NET (without the space) that sounded to me as a f***ing werid library, that I did not know either. Google on AFAIK.NET (without the space) did not result in anything... So please treat others, the way you would be treaten.

Thanks!!!

can you connect to anything else on your computer from outside? I would try to find a solution with a trained network-admin.

wow fast response i didn't expect that heheh
yes i can connect remote, i run my machine as server i have site hosted on my machine all works fine...
|

How do you identify the machine you want to chat with?
are you using a public IP address? over the Internet IP addresses are different from your local IP addresses. And they vary over time.
See e.g. here[^].
A more expensive Internet subscription may yield a static IP, an address that is constant over time.

Hi All,
Actually i am trying to send attachments by using System.Net.Mail.SmtpClient.Sometimes the Timeout error is generate.
So please suggest me what is best timeout intervel for sending 10 mb data.
Thanks in advanced
If you can think then I Can.
|
|
|
|
|
There is no "best timeout". Since the users connection speed can vary greatly, any timeout you can come up with would be pointless if the users connection slows down.
|
|
|
|

Hi,
You need a variable timeout.
I would experiment sending mail manually with different attachment sizes, and note the times it takes (say for 1MB and 100MB).
Then I would set up a linear timeout, with a minimum and a safety factor, say
3*(t1MB + t100MB * actualTotalSize/100MB).

Hi Guys, just loaded vb 2005 onto my PC to start a project for a local club.
Basically they wish to record times that a competitor crosses the line. Each competitor will have enough time in between them to allow the user to enter competitor number.
I have created a text box for the user to enter rider number, a timer that updates with current system time, and when user clicks button it records the rider number and time the button was clicked. Nice and simple.
But, whats the best way to allow this for 100 competitors, for the programme to record each one on a separate line.
The data will also need saving, but Im not that far yet so really just looking for guidence on where to go from just 1 single input to infinte inputs.
Many thanks in advance

Probably a little overkill, but I would put the button, timer, textbox into a custom control which derives from Panel. Then I would loop from zero to the number of required inputs, adding an instance of this control to a FlowLayoutPanel each time you increment. That saves you the trouble of having to muck about with locations, sizes, etcetera. The other advantage is that when you use a custom control, you only have to make a change to the code in that control, and have that change almost instantly apply to the instances you add to the FlowLayoutPanel
