Contacting The DHCP Server?

Oct 13, 2009

Hello,does anybody know if it at all possible to contact the DHCP server from a VB.NET project with the aim of passing a computer name and it returning the MAC address (and last known IP address). The purpose is that the machine may be switched off which is why we need to go to DHCP Server.Basically need to know the Libraries to imports and get started.

TCP Client/Sever With DHCP?

Feb 8, 2010

I have a simple TCP Client/Server application that ties two pcs on a lan together. This has worked great for many job sites but the most recent has an IT manager that will not allow me to set a static ip address on the server pc.Basically, I was wondering if there was a nifty way to have the client find the server.

VS 2010 Get DNS IP / DHCP IP And Defaul Gateway IP

Jun 10, 2011

I am developing a windows application for my guys on helpdesk to use with our clients. It is going to be installed on the clients' pc's. One of it's purposes is to display all IP info of a computer. Such as the client's IP address, DNS IP address, DHCP IP address, and Default Gateway IP address, but I can only get it to give me the IP address of the host and no addresses of the DNS, DHCP, or Default Gateway. I know that I could run an ipconfig /all and pull the results into the application, but I would like to have it laid out more simply for it to be easier to read for the clients in case we are walking them through some troubleshooting over the phone and we need their IP information. I do not require and am not requesting any source code.

VS 2008 : Use The DHCP API To Retrieve A Computer's MAC Address When Given The IP Address?

Nov 27, 2009

I'm trying to use the DHCP API (using the references on to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on through the C#-to-VB converter but I'm stuck now.

Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

Private Sub GetMACDim client As String = ""        Dim server As String = ""        Dim si As New NativeMethods.DHCP_SEARCH_INFO        si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress        si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client))         Dim res As UInteger        Dim oInfo As IntPtr

At my house we got 6 computers and 5 laptops. Not I want to be able to control them remotely without using external dekstop management or something else. So i can control when my kids can use the computer or not

So I came up with the idea of creating an irc server that listens to commands that I type from my main computer. The commands are no problem for me to program but the irc server itself looks pretty hard. I've been looking on google but cant find a good source to learn it. some other ideas than using irc protocol?

Data Management - Changing Current Database System, MS Access 2007 Front End And MS SQL Server 2005 Backend

May 8, 2012

We are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.

Sql Server - Pagenation On A Blog SQL Query?

Oct 13, 2011

I have a blog (non wordpress or anything) written in At the moment I pull my data back just by bringing in the last 10 results: SELECT TOP (@bAmount) bCategory, bID, bImageURL, bInactive, bLargeImage, bPost, bPostDate, bPostTitle, bPoster, bStyle FROM Blog ORDER BY bID DESC

I'm just going to have back and forward buttons to go through the posts, but how do I do the SQL for say post 10-20 last posts rather than the IDs between the posts. (The IDs are incrimental, but can jump significantly).

So basically when I click back it gives me 10 posts that are 10 older than the first page results?

Sql Server - Sql Query And Double Var Values?

Aug 18, 2011

Im having an issue with a certain query,Dim nwLat As Double Dim Ssql As String

nwLat = nwLatHidden.Value
Ssql = " select * from customer where latitude < " & nwLat
TFRcount.SelectCommand = Ssql

All it does is refresh the page and does nothing; it should populate a chart. However when I replace nwLat with a value (eg where latitude = 56) it works perfectly and populates the chart. Any ideas what's wrong with nwLat?

EDIT: I switched nwLat to long and it works; however it only takes the number up to the decimal and ignores the rest. Any way to fix? (eg as double 56.764746 and long 56)

Sql Server - Store / Query Data In .NET?

Nov 23, 2011

At the moment I am using Access & an OleDb connection to store data. I went down this route originally because I though that this was the best way for applications that I am distributing to my clients.

I would prefer to use something like SQL Server but is this a good idea for software I am distributing? Does the average Joe's PC have SQL Server pre-installed? If not, I suppose I can provide them with a link to download it for free?

Is there any better alternatives to Access / SQL Server?

VS 2005 WMI Query - SQL Server Startup

Jan 5, 2011

I'm writing a program that will be able to start a window service (SQL Server) on demand. Some of our servers have both SQL 2000 and SQL 2005 installed. I'd like to run a WMI query on the server (either local or remote) to determine how many instances of SQL are installed, and then start the latest version of SQL server. Install paths to SQL instances / configs can be different due to SAN configuration, so I need to use a WMI query to get the services.

I was using the following query- "SELECT * FROM Win32_Service WHERE Name LIKE '%MSSQL$%' OR Caption = 'MSSQLSERVER' OR Name = 'SQLSERVERAGENT' OR Name LIKE '%SQLAgent$%'" This returns a bunch of SQL services, so I decided to cut it down- "SELECT * FROM Win32_Service WHERE Name LIKE '%MSSQLSERVER%' OR Caption = 'MSSQLSERVER'" But that query still returns other services (i.e. FullText, Active Directory Helper, etc.) that I don't want. Is it possible to create a WMI query to only look for MSSQLSERVER and SQL Server Agent services? Am I missing something?

Aug 27, 2009

I am working on creating a web app that will query event logs on internal servers for events using a specific ID. Since most of the servers are running Windows Server 2003, I cannot use the preferred System.Diagnostics.Eventing.Reader method that I was hoping to use.

I've seen the mention of using WMI, but would like to avoid this if possible. I have dabbled with the System.Diagnostics class but cannot seem to get it working when running on a server. It is able, when testing locally, to query my event log, but displays nothing when put on the final server. There is no error that is displayed after the program is ran.

Run Query On In - Memory DataTable & Server Data

Jun 14, 2009

I wrote a procedure that builds a DataTable in memory using data stored on our DB2 database. The function builds a Multi-Level Bill of Materials (BoM), meaning that the data cannot simply be queried. The function works great and returns a nicely arranged DataTable object. However, I then need to query the in-memory DataTable against other tables on our server. What would be the best way to approach this problem? Should I make a DataTableAdapter for the Server tables and then build a DataView? I don't have too much experience yet with Data objects. (By the way, I looked into LINQ to DB2 and even installed IBM's addin's, but our server doesn't seem to support it at this time.)

SQL Query Works In SQL Server But Not When Called From Checkbox

I've got a datagrid with checkboxes which calls a routine called checkbox_CheckedChanged. So far, so good. I've managed to get it to work out the value of another column in the dataview, which allows me to ascertain the id of the row I'm dealing with. I'm trying to get it to change the value of the column which defines the initial value of the checkboxes, but the SQL I've written doesn't work when called by - it does work when entered manually into SQL server, however.

Multi - Table Join Query In ASP.NET To SQL Server Via LINQ?

Jan 29, 2012

I'm working on an ASP.NET 4.0 site, which I inherited ownership of. It has a number of existing LINQ datasources pointing to individual tables. For example, to the Patient Encounter Summary table in SQL Server. The problem is in displaying the data there. It's a normalized database, so that table contains (for example) the provider ID, rather than the provider name.

It's simple enough to join the Patient Counter Summary to the Providers table (in SQL)... but how does one do that in ASP.NET? I'm not sure of the correct nomenclature, but the 'mid layer' is VB.

Sql Server - ExecuteScalar And SqlDataAdapter.Fill Behave Different For Same Query?

Jul 8, 2011

I have a big stored procedure that I run. At the end its supposed to select a singe value to say if it succeeded or not, so I run the query as

Dim Command As New SqlCommand(SqlString, Conn)
Return Command.ExecuteScalar()

Which works. However there is an error in my stored procedure. I know its causing an error because the logic in the stored procedure rolls back the transactions, and after the Execute Scalar call, my transaction count is down to 0 and the my data hasn't changed. However no SQL exception was generated.

The strange part is, I changed the code to grab all the result sets from the SP to see if I could get more information. So I called the same SP like this,

Dim DAObj As SqlDataAdapter = New SqlDataAdapter
Dim CommandObj As SqlCommand = New SqlCommand(SQLString, Conn)
DAObj.SelectCommand = CommandObj
Dim DS As New DataSet()

When I run this, with the exact same sql as before, executing the exact same stored procedure, this time I get an SQL exception because one of my nested SP calls was missing required parameters. So what could cause this? Why would running it one way produce an error and the other way have the error but not report it? Is the difference on purpose, or some kind of obscure bug in ADO.Net?
