When I store a binary file in a MS Sql table & then retrieve it & write it back to disk the new file is always 1 byte bigger than the original file, no matter what the file type. Is this normal? The files all open fine in their respective applications, but I'm just wondering where the extra byte comes from & if I'm doing something wrong in my code.

Using cmd As New Odbc.OdbcCommand("insert into mytable values (?,?)", con)
Using fs As New IO.FileStream(filename, IO.FileMode.OpenOrCreate,
I am trying to store a .png image inside a database using SQL Server 2008. I have done this just fine using mySQL but for some reason it looks like this when placing it into ms SQL Server:
I recently came across a problem for image file storage in network.I have developed a desktop application. It runs in network. It has central database system. Users log in from their own computer in the network and do their job.Till now the database actions are going fine no problem. Users shares data from same database server.

My xml files were looking a bit clumsy when i read them, what i have done now is to save them in the xml in this format:
vb.net <field>{value1|its partner value2}</field>
i noticed {|} this is the format that vb.net uses for arrays, i was wondering if that's an ok way to store things, on retrieval once i get the node value, what would be the best way to break up the {value1|it's partner value2} variables to use, explode the | and get parts (0) and (1)?
Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)
Does VB2008 have the same limit on resource files as VB6? I was trying to store a large text file in my VB6 app (almost 3 mb) but all I could access was 32k of the file. I need to be able to compile the 3mb file into my .exe.
I was wondering if it would be possible to check the file size of a .exe on a website and see if it's greater than or less than the program running it?
I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:
VB .NET Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories) Dim lvi As New ListViewItem Dim fi As New FileInfo(filepath.ToString)
[code]....
It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.
Dim strUserDir As String = Environ("USERPROFILE") For Each foundFile As String In My.Computer.FileSystem.GetFiles( _ strUserDir + "\AppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5", _
[Code]...
But How can i make it show the file size of that folder? or the "foundfile" string?
I have a vb .net ArrayList that I would like to store in one field on my Ms SQL 2008 database. Is it possible to put it in and get it back out as an ArrayList? I'm guessing i need to break down the Array some how and store it as a string, then rebuild it when reading back as i dont see any datatypes for sql that are for arrays. Which is a bummer for me! edit - The ArrayList stores a set of quote ID's. There is no limit to how big it is so it could hold 1 or 1001 different ID's
i am making a project and in that getting storing and loop problems there are two fields serial no and quantity when quantity is entered serial number must be asked then only and the number of times quantity is entered that many times serial number must be asked also serial number is from to too like 1 to 6 or 1 to 5 so i have to taken 2 textboxes serialfrm and serialto to store but now the problem is that i am not able to write proper code for it either it doesn't get saved to the particular name to which both fields belong or it keeps saving without stopping.

Im trying to resize a picturebox dynamically using .size.height and .size.width Its not working. This is the error message: "Expression is a value and therefore cannot be the target of an assignment." Never used height and width before. Been trying to find the answer, but it seems beyond me. Im sure its easy. Anyone know whats wrong with this?
I have a question regarding multiple page printing. I know that it has to do with e.HasMorePages. I know that there has to be a condition that sets that flag to true and back to false or you get caught in a never ending print page loop. However, I have no idea where in my simple little print block here to implement that. As you can see I'm just printing a readline. Sometimes the file extends past a single page though depending on circumstances.
Dim strReader As StreamReader strReader = File.OpenText("auditlog.txt") Dim x As Integer = 10 Dim y As Integer = 10 Do While strReader.Peek <> -1 e.Graphics.DrawString(strReader.ReadLine, New Font("Times New Roman", _ 10, FontStyle.Regular), Brushes.Black, x, y) y += 12 Loop
I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web (or local) fill the size of the webbrowser - almost like a mini browser if you will.
Can anybody help me, i am having challenges getting collections value into the database
Here is my sample code. but is not working at all rather is crashing the applications
Dim collections As New System.Enrolment.CustomerBiometricsCollection() collections = Me.PrintCaptureWizard1.ShowDialog() Dim dbs As New DBClass Dim mee As String mee = dbs.ConnectionString Dim conn As New SqlClient.SqlConnection(mee) conn.Open() Dim ds As New SqlCommand("Custoon", conn) ds.CommandType = CommandType.StoredProcedure ds.CommandText = "CustBiometrics" For k As Integer = 0 To collections.Count - 1 ds.Parameters.Add("@TemplateID", SqlDbType.UniqueIdentifier).Value = New Guid(TextBox1.Text) ds.Parameters.Add("@TemplateIdentifierID", SqlDbType.UniqueIdentifier).Value = (collections(0).TemplateId) ds.Parameters.Add("@CustomerID", SqlDbType.UniqueIdentifier).Value = New Guid(id) ds.Parameters.Add("@Template", SqlDbType.Image).Value = collections(0).PrintTemplate ds.Parameters.Add("@TemplateSize", SqlDbType.Int).Value = collections(0).Size Dim dr As SqlDataReader = ds.ExecuteReader() dr.Close() Next k conn.Close() MessageBox.Show("Record Inserted")
Here is the code I used to store an image in my database (SQL Server 2008 R2) using VB 2010. The images get stored but the problem is the clarity of the image is lost when retrieved and seen in a picture box.
Public Function InsertUpdateImage(ByRef _SqlConnection As System.Data.SqlClient.SqlConnection, ByVal _Image As System.Drawing.Image, ByVal _ImageFormat As System.Drawing.Imaging.ImageFormat) As Integer
I am using an Access database and vb.net 2010. I have created a table in the database with columns for title, datein, dateout and roomnymber. In vb.net 2010 I made a distinguished title = combobox, datein and dateout = DateTimePicker. When I click on F5, an error occurs: INSERT INTO Syntax Error in statement. [Code]
I am in front of a great dilemma whether to store files in Database or doing it the standard way. I would choose the second option, but my application will be used by multiple users, so I am doing it by Web Services.
On the one hand, storing in database will be very useful as every user would have access to everything very fast, not caring about file paths, locations and so on.
On the other hand, if this table consists of 1000 files, wouldn't it be a bad idea as there should be some performance loss?
At the present moment, I am using mysql as database, but I am thinking of moving to SQL Server, but I suppose this is not DB Issue.
I'm trying to store three images from a form (PictureBox's) into a SQL Database (MSSQL2008) The below does what I want but is clearly inefficient. Any pointers on what to change to improve this?
Private Sub SaveImages() Dim ConStr As String = "Data Source=SERVERSQL2008;Initial Catalog=NorthPole;Integrated Security=True"
I am using vb.net (visual studio 2010) and have made a form application that uses a login screen. All that works but I am having trouble any firm way to encrypt the passwords in the database. The encryption doesn't have to be very high standard as its just for a college project. Whats the best way to encrypt the password into the database? Or just encrypt the password string, I can then sort out the database end myself.
I developed a form application on my computer, but when it was used in another computer with different screen size, i was told the form didn't fit. Do I have to adjust the form size or any other ways to let the form compatible on different screen size? (could be different screen size or wide screen)
