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 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

vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" 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

Getting An Invalid "Invalid Length For A Base-64 Char Array"?

Sep 9, 2011

where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.

Private Sub GetReport()
Try
Dim hawbs As String = String.Empty[code]....

The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.

Using A .net Dll In C#. Getting 'invalid Argument'?

Apr 19, 2011

Got a strange one and I know it is something silly but I can't see it for anything I have a DLL created in VB.net (No I can't change it! :-)) and am calling it from C#. The problems come at the point the object is created in C# and I get the message that it has "some invalid arguments".

The constructor code in the DLL is as follows:

Sub New(ByRef Connection As IConnection)
The code in C# is:
IConnection conn = new Connection();
CustomObject test = new CustomObject(conn)

It is happy with the first line but it gives the error message ("some invalid arguments") on the second line. I have also created a secondary project in VB.net and called the DLL and it works fine there.

.net - Invalid JSON Data

Feb 7, 2011

I have the following jquery which is invalid:

{
"id": 12,
"heading": "heading goes here 3",
"content": "<p><span style="color: #ff0000;">content</span> <u><strong>goes </strong></u><span style="color: #ffffff;"><span style="background-color: #ff0000;">here</span></span> 3.</p>"
}

I am generating this with asp.net (vb.net) from data stored in a database. I think I need to somehow escape the double quotes within the content section of the json data. How do I do this?

Hardware Interface Dll Invalid?

Jan 1, 2011

I am attempting to write some interface code for a piece of hardware. Because the hardware requires use of 12 control lines, I believe the parallel port is the easiest connection method. After some research, I have discovered that inpout32.dll is the most efficient solution with only two commands to worry about (inp32() and out32()). I have downloaded the dll and attempted to place it in my code using both dim and declare statements. The file resides in the root level of the project folder as well as another copy in the windows directory. No matter how I try to call the dll it gives me errors stating that libraries were expected and that the dll does not exist.
