Code To Autodiscovery PCs On An Ethernet Subnet?
Jan 6, 2011I am working on an application that collects data from PCs on the network using WMI queries. Is there any sample code that knowing the subnet would autodiscover PCs nearby?

View 13 RepliesReading Ethernet Port Pins
Jun 10, 2011[code]Through these ports I have been able to connect simple press-button triggers (or switches) and programatically "read" them. i.e. tell when they are open or closed, grounded to earth or not.With modern PCs I am now somewhat limited. I can still use the MIC port and USB port (when connected to a USB/Serial cable) but since WiFi, my ethernet port is now "available". If you've read this far, you already know my question. How can I "read" the ethernet port pins. I realize that perhaps not all the pins may be simply read, but perhaps one or two at least.

Write Directly To Ethernet Port?
Feb 7, 2011I am writing an app that does part of what another app does (I have no access to the source for the other app other than to see Wireshark output.)
I need to send a broadcast over the LAN and then parse the results. However, the sending of the broadcast seems to be code that is direct to the LAN connection, as in it doesn't seem to write to a standard IP/port combo.
I see apps like Raw Ether that do this at a cost of hundreds of dollars.

Feb 5, 2010I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test. The calculator can do one of two things:
1 - given an existing network and CIDR(mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.
2 - given an existing network and CIDR(mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.

IP Subnet Calculator - Networks And CIDR (Mask)

VS 2005 Verify Good Subnet Mask
Aug 24, 2011I am trying to verify that I have a valid subnet mask. I have already verified that the string format 255.255.255.0 or whatever 255.255.240.0 converts to a UInt32 but now I need to make sure its actually a subnet mask.
The bits should be split between 1's for the network part and 0's for the host part. It should start with all 1's and end in all 0's if it goes from 1's to 0's then finds any more 1's its an invalid subnet mask.

Enumerating Host Addresses From IP Address And Subnet Mask
Sep 24, 2011As part of my application I am hoping to be able to get the user to enter their IP address and subnet mask which will then enumerate all of the hosts in between which can then be scanned for various open ports/applications installed.
For instance, With a network of 10.91.100.0/255.255.255.252 hosts are valid 10.91.100.1 - .2
How can this be done in vb.net? I would assume also some error checking would need to be put in place to confirm as to whether the subnet mask was valid as well?

Another OPTIMIZING Macro Vba Code For Excel 2007 - The Code Is A Sort Of Transposer For Data
Sep 9, 2011this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.

View 2 RepliesMSI Returned Error Code 1638 When Re-Installing Visual Studio 2008 - .NET Framework | Dream.In.Code
Jan 9, 2012I realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3
Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.
