Add More Than A Single Photo To Database (one Cell)?
Nov 4, 2011
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 am trying to update a row or a single cell in ms access through vb.net. But when i update the text box named NRIC, say for example i want to update "s4522147B" to "tr4521856C" and mean while leaving the other fields the same.
But the thing is when i make the changes in nric.text (textbox), the dataset actually updates the whole column in the table instead of the selected textbox.
Below is my code for the update part

I am using MS Access Database. Now I have to update a particular cell value. Here is my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim Presc As New System.Text.StringBuilder
Dim prs As String(), j As Integer
[Code]....
This code updates all the cells in that column. I want to update only the particular cell having Case_ID = str Where I have to add the WHERE clause (WHERE Case_ID = " & str & "

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.

But I am getting an error on the second select variable stating: Range variable 'Value' is already declared
What I have read shows that I can select more than one variable.

I'm trying to get a single value from my table in a database. They are all given a unique id when stored. Here is the code I use to put the in:

That was so you could get an idea of what I was looking for, I'm not looking for sql statements, I don't know how to use them. Just keep in mind, this is all vb.net/asp.net.

Looking for the simplest way to get a single value from a database. This gets confusing when you consider all of the 9,000 ways that exist to do this in a .NET language. SqlCommands, DataReaders, Recordsets... Assume I already have a connection to the DB opened. I simply want to do something like this:
Dim age As Integer = <SQL statement here>

I am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4. The catch is I don't want it to update every time the sheet is recalculated due to updating links in other cells on the sheet. ONLY when Cell A4 Changes. What do I do?

In my contact manager program I have been storing information by reading and writing comma delimited files for each individual contact, and storing notes in a file for each note, and I'm wondering how I could go about shrinking them all into one file effectively. I have attempted using data entry tools in the visual studio toolbox and template class, though I have never quite figured out how to use them. What would be especially convenient is if I could store data as data type IOwner (a class I created) as opposed to strings.
I'd also need to figure out how to tell the program what to do when a file is opened (I've noticed in the properties how to associate a file type with the program though am not sure how to tell it what to do when it's opened).
Edit:
How about rephrasing the question: I have a class IContact with various properties some of them being lists of other class objects. I have a public list of IContact. Can I write Contacts as List(Of IContact) to a file as opposed to a bunch of strings?
Second part of the question: I have associated .cms files with my program. But if a user opens the file, what code should the program run through in an attempt to deal with the file? This file is going to contain data that the program needs to read, how do I tell it to read a file when the program is opened vicariously because the file was opened?

I am trying to read a single result from an SQL table. I tested my query in MySQL Query Browser and it returns a result of USER_ID=4. My query:
SELECT USER_ID FROM aaalogin where NAME = 'administrator'
I believe my error is due to some "double quoting". I have a "txtUsername" textbox on my login form. I want to inject the typed entry from this textbox into my SQL QUERY. Notice the end of this line, I have tried tons of combinations, nothing works.
myCommand.CommandText = "SELECT USER_ID FROM aaalogin where NAME = " & " ' txtUsername.Text ' "
The result is ALWAYS "0" though, which is useless to me.
Full code below:
Imports MySql.Data.MySqlClient
Imports System.Data
Public Class frmLogin
Private Sub cmdCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdCancel.Click
Application.Exit()

I have a field in my database called Amout Ordered, I want to update it with the amount of each item ordered, and I can't figure out how.

I have an application which takes input on a local machine and sends it to a database stored on a server. I'd like to be able to deploy my application over a number of computers (all on the same network), all of them updating the same database (on the network server).First of all, will this be possible without putting together a completely new application to handle all connections to the database and sorting the entries?
