Save The Photo Into The Database Table Using Binary Method
May 20, 2012
I have a project in VB2010 it is well connected to the database (DB.accdb) access2007. I'm trying to save the photo into the database table using Binary method. I am successfully able to (Save, Search). my problem is in the EDIT button : I'm supposed to search first to return\display the info+Photo on the form controls (Textbox + PictureBox), now i want to do EDIT, i use sql string : SqlStr = "Update MyTable Set Field1 = '" & Text1.Text & "', PhotoOle = [b]????[/b]"
I'm not able to convert the PictureBox That contains the returned photo to Byes() using : ImageBytes = Ctype(PictureBox1.Image, Byte()) .... not working . -Or- ImageBytes = Ctype(DaraRead!PhotoOle, Byte()) .... not working either.

I am quite new at this so bear with me. I am trying to just download data, save it row by row into a database, then upload it (sorta a backup). I am using vs2010 and VB. The database I have in vs is a .sdf (not sure if i should remake as a .mdf) and the download of data is working fine. Saving it into a table isnt going so well. I am using a form to click a button to start the download, and most of my vb code is in another vb file. Making it into a method is causing me no end of pain due to the object refernce errors and nonshared reference errors. But I go to far for this. Anyways I tried to use

My query is i want to save record from an excel sheet to my Database Table.
But i dont want to insert the Excel sheet as a whole rather i want to insert the record in my database table Row wise.Inserting the records is not the only thing but my major issue is i want to check and compare the Primary Key column of my Table with the Column in my Excel.
Suppose Table1 is my Sql Database Table,and RegistrationNo is the Primary Key Column.Similarly there is also a column of Registration Number in my Excel Sheet.
Now before inserting each record the RegistrationNo column should be compared.If the a registrationNo in the excel sheet say RegistrationNo 112 is already present in the table then it should not Insert the record and if its not present then it should insert.
Also the other issue is the number of columns in my Database table are more than the number of columns in my excel Sheet.So the columns that are not present in the excel sheet should be set to NULL while inserting the record in the Table.

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"

I'm creating a database for photos'.
The issue is that I have a need to upload a set of photos to the database instead of a single photo.
This would be all fine and dandy if I knew how many photos would be added at once but in this case it could be 1 or 100.
I have my database (setup in details) and dragged onto my form. Right now I only have a picture box for my picture to place into the database.
So what's the best way to upload numerous photos to a database without having to create 10000 cells in my database?

I haven't done any VB coding since school (15 years ago) but currently have a need to run what "sounds" a fairly simple app at work. I'm hoping some of you might be able to give me some pointers as to whether or not my idea is possible, and if it is, how best to approach it.
I work for a company where we send a number of standard emails to potential clients asking them to contribute to our magazine . if no response we then send a number of follow up emails. each and every time I send a new email to a new prospect I'm editing one of our template emails, putting their name and email address into outlook and manually sending emails. Then for every reminder I'm going back into outlook, clicking reply all and then c&p'ing our second or third reminder emails in each and every time. needless to say at least 2-3 hours of my day are spent editing and resending the same emails on outlook.

I have a delete method for a binary search tree. It only deletes the last two entered values. When trying to delete the root or anything to left of it it returns a null pointer exception.
PublicFunction Delete(ByVal key AsInteger) AsBoolean Dim current AsNode = root Dim parent AsNode = root Dim isLeftChild AsBoolean = True While (current.value <> key)
parent = current If (key < current.value) Then isLeftChild = True current = current.rightNode Else

I am trying to serialize object in method binary mode. However, I would like to get a file in human-unreadable format. which means i want to encrypt file. In my memory, if i want to write text into binary file in C, when I set writing mode as binary, I will get a file in human-unreadable format, but in .net, I can't get that.

I have a flat file that is sorted by account number. I am migrating an application that was in vb6 to .Net. The application uses Random file access and uses a binary sort method to find a record.
Here is the code
Do While (low < high Or low = high) And (f = 0) 'Checking for an account match
middle = (low + high) / 2
FileGet(FileNum, Record, middle)
If Account < Trim(Mid(Record.Data, Byte1Start, Byte1Len)) Then
[Code] .....
From reading up on this in .Net it seems that using the Binary Reader seek method would be the alternative to using old vb6 random access code. The problem is the Binary Reader Seek method goes by Byte position instead of record number. How to convert my code to use a binary reader.

I'm trying to save a binary file stored in a SQL database with a SaveDialog, the function RetrieveFile retrieves the specified file from the database as a Byte array, here's what I have so far:
Private Shared Function RetrieveFile(ByVal filename As String) As Byte()
Dim connection As New SqlConnection("Data Source=SERVERSQL2008;Initial Catalog=NorthPole;Integrated Security=True")
Dim command As New SqlCommand("SELECT pcfFile FROM Items WHERE pcfFileName=@Filename", connection)
command.Parameters.AddWithValue("@Filename", filename)
connection.Open()
[Code] .....
Files are saved as "SqlDbType.VarBinary" within the database.
I get: "Index was outside the bounds of the array." on:
Dim retrievedBytes As Long = reader.GetBytes(1, startIndex, buffer, 0, ChunkSize)
The MemoryStream appears to not be retrieving the data yet the SQL syntax is correct.

I need to add some information to a PDF (Trim Box proporties, actually replace Media Box proporties with Media Box and Trim Box proporties), and I dont have the support in my PDF-motor. So I found out that I can use Notepad++ to open the PDF as a text file and simply add the Trim Box properties as a string and save it. Now I want to do it automatically with vb.net. When I use Stream Reader/Writer the PDF gets destroyed and loses information (Stream Reader dont read all the NUL, SOH, STX etc. I guess). I tried to read the PDF using ReadAllBytes/WriteAllBytes and then it works good, but then I don't know how to replace "Media Box ..." with "Media Box.Trim Box.". I try to use IndexOf but I can only search for single Byte not the whole string. I'm not good in binary and thats perhaps the problem :-). Does anyone have a better way doing it or how do I search for my string "Media Box" in binary?

I'm designing a very simple program that will need to save both data and photos to a cd but my code refuses to let me do it. Here is what I have:
FileOpen(1, "E:FileWithData.dat", OpenMode.Binary)
FilePut(1, AString, 10)
I keep getting an incorrect function at FileOpen
I saw some methds which take numerous lines of code but I like to keep my code very simple so I can easily tell what it does.

I am trying to write data to a binary file using the Print() method, but when I run it I get the System.IO exception Bad File Mode.
Here's the code for the FileOpen declaration, that might have something to do with it?
FileOpen(filenumber, "path to file", OpenMode.Binary, OpenAccess.Write, OpenShare.LockReadWrite)
Print(filenumber, expression(variable))
