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.

View 5 RepliesHello,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.

View 2 RepliesI 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.
View 6 RepliesWe are creating a Who wants to be a millionaire style game in VB. Our server is pulling information such as questions and answers from a Access Database and sending them to the contestants (Clients). All transfer of information is directly from the server to each client. One of the "Life Lines" we want to use is "Ask a friend", where one client is able to Instant message another client for a short time to get help on the question.

I'm trying to use the DHCP API (using the references on pinvoke.net) 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 pinvoke.net 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

Question: How to pass the current user on the web page from the IIS server to the Reporting Services Server.I have seen this topic throughout the forums. However, the answers are always hard code the user in web.config - use a login window and pass those fields to the IReportServercredentials or create one user for everyone.
When the person who asks the question comes back and says that doesn't work there is not answer.Does anyone know how to do this? I have VS 2008 ( and 2010 ) I am sending the info to SSRS 2005 server.As anyone using SSRS knows that if the reports have parameters and udf behind the report to inspect who the user is, then you have to pass that user to the report.

View 14 RepliesI have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
