Making SlideShowExtender Retrieve Images From MS Access Database?
Jan 10, 2012
In my Microsoft access database I have a table called Picture and 3 fields: ID, Name, Image. I was wondering if it was possible to get all the images from the field 'Image' and display them into SlideShowExtender.
I am trying to retrieve jpg files from access database this is the code I used to insert the jpg picture into the database. I am using vb.net 2010 and access 2010
Dim jpgFile As String = "C:UsersPublicPicturesSample PicturesJellyfish.jpg" Dim o As System.IO.FileStream = New FileStream(jpgFile, FileMode.Open, FileAccess.Read, FileShare.Read) Dim r As System.IO.StreamReader = New StreamReader(o) Try
SQL Server supports the ability for clients to store objects within tables.Create Field that data type Image and Initialize byte array with a null value initially.Use FileInfo object to get file size.Open FileStream to read file.Use
store and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.
I am using bindings and tableadapters to store the details in database and retrieving information from db. Please if you have code or anything which is working for me, please post it here... how to store image and retrieve it SQL Server through vb.net provided there's LAN computers who are also sharing the SQL Server database.
I have made a project(made a new data set and forms made by dragging data set entries to form ) in vb.net in which i used ms access as database and now i created a setup file for it but when i run is its giving error regarding some connection to database.?
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)
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 using the following SQL statement to retrieve information from an access 2003 database but this command keeps stripping out the proceeding 0 from the number of the month. The variable is called TBookingsDateFulldate
Dim sqlQuery As String = String.Format("SELECT [ID], [Date], [Zone], [Year], [Subject], [Teacher], [LessionID]" & _ " FROM tblBookings" & _ " WHERE (((tblBookings.[Date])={0})" & _ " AND ((tblBookings.[Zone])='{1}')" & _ " AND ((tblBookings.[Active])=0)" & _ " AND ((tblBookings.[LessionID])='{2}'));", TBookingsDateFull, TBookingZone, TBookingsTimes(B, 0))
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.
Not sure if this is the right Forum to post this question. If not guide me where to post... I have an Access database that I would like to be able to share with Multiple user cuncurently... I have seen it is being done but I am not sure how? Or may be I should be using SQL Express.
I'm looking to retrieve all the entries from one column of an access database table and copy to an array. this array i will then be randomly selecting values from it to create foootball fixtures. I'm confident of being able to achieve the random side of it but i'm struggling to get the records into the array.
I am looking for ways to retrieve data from textfile and save it into access database. Currently, I am doing a attendance record project. I need to save the attendance record which is given in a text file to the database. The version of VB i using is VB 2008.
The content of the text file look like this: E010,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR E022,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR
[Code]....
I tried to create a class and store the record but it just don't work.
I am trying to generate random images from access database using hashset as it is said to be unique and there won't be any repeated images appearing. But, it doesn't seem to work.
How can i get it to work? By the way, i am very new to the concept of hashset. Private Function GetImageFromByteArray(ByVal picData As Byte()) As Image If picData Is Nothing Then Return Nothing End If
' is this is an embedded object? Dim bmData As Integer = If((picData(0) = 21 AndAlso picData(1) = 28), 78, 0)
' load the picture Dim img As Image = Nothing Try Dim ms As New MemoryStream(picData, bmData, picData.Length - bmData) img = Image.FromStream(ms) Catch End Try
' return what we got Return img
End Function

oledbconnection.Open() Dim command As OleDbCommand command = New OleDbCommand("select count (*) from PicturesDisplayed", oledbconnection) Dim count As Integer count = command.ExecuteScalar() oledbconnection.Close()
Dim randomImage As New HashSet(Of Integer) ' Create a integer and new Random object Dim intPic As Integer Dim rand As New Random
'Pick a random number between 0 and the number of images in database intPic = rand.Next(0, count) randomImage.Add(intPic)
PictureBox1.Height = 256 PictureBox1.Width = 256
PictureBox2.Height = 256 PictureBox2.Width = 256
Dim pic1x As Integer = _ (Me.ClientSize.Width - PictureBox1.Width) 2 Dim pic1y As Integer = _ (Me.ClientSize.Height - PictureBox1.Height) 2 PictureBox1.Location = New Point(pic1x, pic1y)
Dim pic2x As Integer = _ (Me.ClientSize.Width - PictureBox2.Width) 2 Dim pic2y As Integer = _ (Me.ClientSize.Height - PictureBox2.Height) 2 PictureBox2.Location = New Point(pic2x, pic2y)
' Now set the picturebox image equal to the image chosen from the array randomly using the random PictureBox1.Image = GetImageFromByteArray(DS.Tables(0).Rows.Item(intPic).Item(0)) PictureBox1.Visible = True PictureBox2.Image = GetImageFromByteArray(DS.Tables(0).Rows.Item(intPic).Item(2)) PictureBox2.Visible = False

How can I save a date data type from vb.net to access that access have date/time in its data type and how can I retrieve it? I also want to use datediff to auto calculate the age to be shown in a textbox.
i've download the 101 Visual Basic and C# Code Samples from downloads/details.aspx?familyid=08E3D5F8-033D-420B-A3B1-3074505C03F3&displaylang=en i was going to learn "VB.NET - Data Access - Read and Write Images from a Database" from that 101. the program is written in 2003 the conversion of the problem to 2005 and 2008 failed.
I have this program that is suppose to take the path I provide it and use it to save an image to my access database. But it keeps giving me ""Syntax error in Insert Into Statement." error message.
how to retrieve image from access database?.. I've just finish retrieving data to the datagrid view. 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 am at a stand still on this one. I know how to connect and add to the database, I just don't know how to retrieve the information so that a user can see it! If anyone could help me with code or another example.
