VS 2008 Method Of Retrieving Hardware Information?

Nov 17, 2009

I need to pull hardware info and display into some type of a control like a ListView. I've been doing some general research and found that most people have used WMI. I would like to avoid WMI if possible because of possible compatibility problems.However, if that's the best way, then that's the way I'll go.I was wondering if anyone knew of other methods, perhaps an API or other unmanaged code?

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes

Feb 2, 2011

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?

Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long

Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

Retrieve Information From A Binary File, Alter That Information, And Put It Back Into A New File?

Aug 27, 2009

I am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.

This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:

Read through the file with a system.io.binaryreader

Searche for a bytestream that will signal data is coming

For example:

If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....

And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?

I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.

MySQL Count Rows Count Rows And Gain Access To Other Information In A Row Based On Provoided Information

Oct 8, 2009

I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)

So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).

Ok, I was able to figure it out: Ok, I was able to get it working, I was using the wrong "slash" character I was using the forward slash instead of the back slash:

Dim sourcefile As String = Server.MapPath("VitualFolderName") & "ImagesLAPDPatch.jpg"

I need this sub to retrieve the values that were filled in on the form, but the things I need to retrieve values from are not asp controls, they are simple <input> and <select> tags.

I am doing invoicing using VS2008 VB. I use Crystal Reports to produce the invoice. I create an in memory dataset to pass to Crystal Reports. What I would like to do is save the dataset I sent to Crystal Reports as an audit trail of the exact invoice. It would only be retrieved in the event of a dispute concerning the original invoice. I thought of using the WriteXML, ReadXML. But that would overwrite the existing XML. Does anyone have a better way of saving the XML for future retrieval?
