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)
I am building a real estate website. I have a table for properties (i.e. "houses"), a table for pictures, a table for features, etc. So each property's data comes from three, not only one table. I need to provide a function that retrieves requested property data depending on a search criteria, for example:

I have three class files, accounts.vb and transactions.vb in addition to my form.vb. I am unable to retrieve a member variable from on class from inside the other. When the combobox index changes, the program loads the correct account (checking or saving) from two different sequential files. I don't think I have the calcBalance procedure in the correct class file. And that is what I am having trouble with. Accessing it to display it. [Code]

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.

View 6 RepliesI am trying to design a table type structure that contains rows and cells. I intend the cell class to have a value property. I'm trying to work out how I can create a value that can return some defined different types e.g integer, single, date, string. I'd like the cell value to be strongly typed, but I am unsure how best to get this working.
My thinking in code so far:
Public Class Cell
Private _value as object
Public Property Value as Object // How can I define this so that it return a Type

Return _value

Created 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?

The main problem is I couldn't display the result when I retrieve data from database.
1. On Picture 1 above, for the Dg_Details, I set the Columns in two type, textbox and checkbox. But, for the datagridview1, I didn't set anything.So, when I bind data from database to Dg_Details and datagridview1, the datagridview1 display the data from database, but the Dg_Details doesn't display the data. Below is the code I written in my form :
Try
objCommand = Me.MyConnection_F.open.CreateCommand
objCommand.CommandText = "select Reg_Num, Reg, Golf, Course_1, Course_2, Course_3, Course_4, Course_5 from Invoice_Reg where Receipt_No = '00001'"[code].....
I think that's happen because the Dg_Details already set and it blocked the result data from database.
