Feb 15, 2011

I want to retrieve also the image (also stored in the database as path inside the table where the data stored) in the picturebox. When i clicked the specific data in datagrid view, it will show preferred image to picturebox.
I'm new to visual basic 2010 ultimate. I want to make a search button to "search" ms access 2007 database for specific data and display the results in datagridview. I also want to display the data to textboxes.
how to retrieve an image from database using image URL and insert it in grid view in vb. net ?? thats my data base table i have 3 columns in table image (ID as int , imageName as varchar , imageURL as varchar(max) i want to insert the image in a grid view but when i run this code i only get the last image in my table everytime thats my code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load '--------------------------------------------------------------------------- Dim dt As New DataTable() Dim strConnString As [String] = System.Configuration.ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString() Dim strQuery As String = "select * from image"
So I've been playing around with SQL strings in VB 2008, and trying to retrieve records from a database and display them in a data grid view. This is the part of the code that gets the fields and displays them in the data grid view:
What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
I am having trouble in browse & then save an image to SQL Server.ALso I want to retrieve that image.This is the code to browse image & show it in PictureBox1 Control
Public Sub SelectImage() With OpenFileDialog1 '.InitialDirectory = "C:"
[code]....
But don't know how to pass it to image parameter .Also is there any way that I can save image on Local drive & just save the url /location/name in database?
1) Add a new record - I can currently add records text to access database, but not images.
2) Get the ID [URL]I'm not sure how to integrate this code into my code. I am stuck here.
3) Save the image in the filesystem using the ID as a filename - I can save the upload an image and save the image to a directory on my computer, but I am unable to name the image that of the ID of the access database.
4) Update the database to put the filename in the record you just created. - I am unable to do this as well (obviously).

i am a new user of visual studio 2008i make a database program, but i cant save the image in access data base, i also want that image save a copy file in database.
i am working a "image processing system" project in vb.net using the ms access2007.i have to browse by clicking a button and open a image to display its name to a text box and that image to picturebox.and after that i want to add,del and extract those images to the access database.i want to use datagridview control also.
I'm trying to code a button which has a SELECT statement to get information from one table but I want the information displayed in a data grid view.From the data grid view, this data will be stored in a different table within the same database.Previously i had used a list box to display the information but i could not save it in the data base.[code]Is there any way you can display this on a data grid view like i did on the listbox?Im using a datagrid view textboxcolumn column.
I have an access databse, but the data is link to excel, so i cant changes the data inside access database. However, i just want to retrieve the data inside the access database using VB datagridview, but the system pop out an error said 'cannot find the input table or query'Is it because the data is link with excel, so access databse cannot direct take the data? Below is my code:
Dim myconnectionstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:mydatabase.mdb" myconnection = New OleDbConnection(myconnectionstring)
If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.
