View 6 RepliesI 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.
I have a some information on a textfile. I want to input the customers ID number in a textbox or inputbox and get all the customers information like name, address, Date of Birth, age, etc. I know how to retrieve information from a textfile by typing the name of the textfile a getting all the information in the textfile. How to do is to retrieve certain information from a textfile. How can I type in the customers ID and pull up all the customers information and then store it in an array.

View 5 RepliesCreated an XSD file that represents my table structure from my database. Created a class file to hold my functions such as the one below.
Code sample:
Public Function GetUser(ByVal UserID As String) As xsdUser.UserDataTable
Dim SqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabase").ConnectionString)
[Code]....
Now it seems odd to me to have two files doing what should be contained within just one file. I feel like I should have one class file called "User" and have member variables in there along with the class functions like the one above. But all the tutorials I see are using these data tables. On top of that I'm not sure how to handle the if statement at the end of the function. I don't think I would want to return a whole DataTable since I should only have one row, and I also don't know how I would handle an error if my function is supposed to return a data table. I suppose I could return an empty one and then if the table is empty in my code then I would handle it there, but this also seems messy.
Is this the common way of retrieving information from a stored procedure? Or is there a more up-to-date method that I'm not seeing in my search results?

I'd like to be able to get and set the different information for a user in Active Directory on Windows Server 2003 under Environment and Session tabs through a VB.Net application. I am familiar with System.DirectoryService but I can not find the correct attributes for these particular tabs. For example, I'd like to check "Connect Printer at logon" or set "Idle session limit".I've found the "ms-TS-Connect-Printer-Drives Attribute" and other attributes like it but they are only implemented on Server 2008.

View 2 RepliesI am faced with the prospect of having to completely rewrite the application.I have suddenly started to get this error message all the time - it seemed to start after I added a table to the schema, but deleting the table makes no difference. I can't see anything wrong with the connection string, but as it seems to be entirely undocumented, that doesn't mean much.
The connection string contains DataSource=.SQLEXPRESS;AttachDbFilename=|DataDirectory| est.mdf;Integrated Security=True;User Instance=Trueand certainly the string works when I use "test connection" from the application setting edit box. I am assuming that for some reason it is not evaluating the Data Directory , but can't see any reason why it shouldn't. Any ideas gratefully received! What might be a clue though is that I can't get rid of the table I added. I have deleted it from the database, deleted it from designer and saved the file, but it just keeps reapearing! Even when it is not showing, there is still a
table adapter in the .xsd file. I am reluctant to start editing this manually because of the danger of screwing something else up - I did try but it caused an error somewhere else (VS helpfully didn't say where)

we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.

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 _

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.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?

View 4 RepliesI 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).
