Re: Getting all availabel information of a computer? - Visual Basic Discussion Boards

Hi all,

I have the following problem: i got an ip (such as 209.89.34.23) which associated with a computer current online. How can I get all available information of this computer by using VB and which API should be used?

I know the function gethostbyaddr when i implemented it to get hostname of local network, working correctly. But when use it to get hostname from an internet IP, is not working and raise following error "Valid name, no data record of requested type."

What should i do to get all available information of computer i got the IP

What do you mean by "all available information"? Are you talking about getting any DNS record for the IP address?

all available information here is can be:
- Opened ports
- Domain
- NetBIOS name
- Groups
- Users
- Transport
- Share

I have a question for scan algorithm.

Scenarion:
1) User input IPs range (from IP -> to IP).
2) Application scan the range and return live host associated with IP in range
3) Gather information about IP scanned

Can you show me the way to do this? I mean how to scan and how to find the live host associated with its (with code for scaning process is very helpful)

THen you going to need to use WMI and the System.Management namespace to get at the information. There is no one function call you can make to do this. It's going to be alot of code to write because you looking to get all kinds of dissimilar information.

When use WMI, the target computer must have WMI installed too rite? I want to check every possible getted information. You know what i mean. If there anything available to get, just get other wise do nothing. Therefore, i think should not use WMI.

How about your opinion?

In that case, most of the information you want is not available without writing a client inventory application that must be running on each client machines you want to scan. For that app, you'll have to write LOTS, and I mean A LOT, of code to get each little piece you want and put it together into a form that you can transfer to the server machine collecting this data.

WMI is the ONLY way to go for this if you want to keep the code down to a minimum... Granted, WMI is not available without installing software for it on WIndows NT SP3, Me, 98, 95 and below. Windows 2000 and above come with WMI standard.

Thank Dave for remine me, sound good!

I agree that we must use WMI to get information. Now i wonder how can i do that. I mean, i'm a newbie to do that. Can you show me the way to check for all available port and other information by using WMI (working on Win2K SP4) and programming in VB6

Actually, I'm working on such a solution now. The code is pretty ruff, but it gets the point acrossed. In order to see the SWbem* classes, you'll need to add a Reference to the Microsoft WMI Scripting Library.

Dim wmiLocator As New SWbemLocator
Dim wmiService As SWbemServices
Dim wmiObjectSet As SWbemObjectSet
Dim wmiObject As SWbemObject
Dim intIndex As Long

    On Error Resume Next
    Set wmiService = wmiLocator.ConnectServer(strNameOrAddress, "root\CIMV2")
    If Err.Number = 0 Then

Thank for posting, nice post. I have an example to follow:

I want to display the following information of a remote computer. The following information displayed when i input IP/Hostname then click a function to enumarate the information. I don't know how it process and how can i do that? (i mean the solution, the code and many more, 'cause i'm starting to research it). The result is display while using SuperScan to scan it (for more information please refer to it, i just want to develop an application like that).
The Enumaration Type of display is:
- NetBIOS Name Table
- NULL Session
- MAC Address
- Workstation Type
- Users
- Groups
- Account Policies
- Shares
- Domains
- Remote Time of Day
- Logon Sessions
- Drives
- Trusted Domains
- Services

Hi, I use open dialog control in my VB.NET project to get the file name to the label control on form. It is working fine when I choose the file then it return the value to the label, but How could I control the user if they choose the CANCEL button?

If he clicks the Cancel Button the ShowDialog method of OpenFileDialog button will return DialogResult.Cancel and you can check for this to do what you want. Hope I understand your question.

Thank you very much, now it is working.

Wouldn't it be viable to use a message box to alert the user that he or she has clicked on the cancel button, after using the DialogResult.Cancel to the OpenFileDialog?

Hi,
How could I create COM objects in VB.NET?
I'd be glad if someone tells me.

Thanks.

The question you ask is not that simple. For a small example of this, see Calling a .NET Component from a COM Component[^] on MSDN.

I have a project to make a spread sheet application like Microsoft Excel using c++. I have problem with the library that i should use. Maybe one of you can help me? Thank's before Wink | ;)

First, this is not a very specific question. You say you "have a problem with the library that i should use". But use for what? There are hundreds of libraries out there, all specialising in one thing or another.

Second, and more importantly, this is not the C++ forum. I suggest you post your question to the correct place and then you might get a response that will help you from people who know the subject area.

Do you want to know more?

My customer need to speed dialer program. This is will built into their existing Customer Information System. Whenever they need to call the customer they just need to click on a button and my system need to call to the #. If the line is connected the user just need to pick up the telephone and start talking.

I think i will need to use modem to connect. Problem is if the line is connected, and when the user pick up the phone, my modem is still connected to the line, can they talk like that??? and can i keep track how long they talking to the customer???

i need this urgently, please help. thanx.

You could use the modem or there are TAPI modems/cards that will do this. The TAPI version will give you more functionality over a normal modem. A normal modem will dial the phone andlet the user pick it up when the person answers, but after that, the modem will either hang up or will keep the phone off-hook. In either case, it usually will not start a timer tracking the call and will not let you pick that time up in
your software.

wlho wrote:

Yes, but anyone around will be able to here everything being said and the speaker in the modem usually will not shut off until there is a data connection.

wlho wrote:

Not while using a normal modem. You'll need a device specifically designed for such work.

How can I refresh or reload datagrid? I have a main window there is a datagrid, and a child window to add more data into db, I want the datagrid to reload the new data when the child window close and return to the main window. how can I do it?

Lisa

Use the public void SetDataBinding(
object dataSource,
string dataMember
) of DataGrid to refresh the grid.

where should I call the SetDataBinding? should I call it at the child window when it close?
