Uploading And Image To SQL With TableAdapter.Insert?
Jun 12, 2011
For a project from skool, I been in charge of development, and we already have the system, but they wanted to add images to the project, and since i been using the TableAdapter.Insert commando to add records to the database, I need to know how to send an Image with that command.
Here is my code
EmpTableAdapter.Insert(noemp.Text, nametb.Text, area.Text, DateTimePicker1.Text, "", "Active", "", HERE GOES THE IMAGE )
[code].....

Visual Studio 2008VB.NETFramework 3.5Windows Application
I have a SQL database names TestSQLVB
In it a table called tblTest2, with a three fieldstest2id , int, pk, increment by 1field1, varchar(50)field2, varchar(50)
I have a dataset named Dataset2.xsd
A tableadapter named tblTest2TableAdapter
A insert query names InsertTest2 with fields @f1, @f2 and ExecuteMode = Scalar
When I run the following code per MSDN [URL] the database does not get updated.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim testds As New DataSet2TableAdapters.tbltest2TableAdaptertestds.InsertTest2("One", "Dog")
End Sub

I have a program that is using a dataset class, table adapter, binding source and binding navigator. The program can read, update, and delete rows from the table. However, it doesn't recognize new records and save them to the database when the table adapter's update method is called. (table was pre-populated by another process) The database table is using an identity column for the primary key. On a whim I added code to force an insert of data using the table adapter's Insert method with some hard coded values and this worked.This code was invoked after hitting new record on the binding navigator bar. Looking at the database, I notice the record I forced in skipped an identity value, which indicates to me hitting new record took the previous number. So the question I have is what would keep the tableadapter from inserting the new record when its update method is called?

I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...

I'm using the TableAdapter to Insert rows into a database, when I use execute from the Query Builder, the line gets entered into the database, when I enter it via Form button, it doesn't get entered to the database using the same commands.

I am trying to achieve the following. I have a web page that I want users to upload a .csv file to, that places the file on a local server and then after that the file is then bulk inserted to a sql database. I can't get the file to save in the location mentioned in the script and I would like to do the bulk insert cleaner.

I was working through Beth Massi's article, "Using TableAdapters to Insert Related Data into an MS Access Database" here: http:blogs.msdn.co...s-database.aspx
And I configured the TableAdapter exactly as shown by Beth, yet I am getting an error here:
Me.OrderDetailsTableAdapter.Update(newOrderDetailsRow) The Error says: "You must enter a value in the 'OrderDetails.CustomerID' field."
I am using this code for inserting a related record:
Namespace MyDataSetTableAdapters
Public Class AccessIDHelper
'<summary>
[Code].....
I am not able to insert and move on as I am getting the error marked above.
What could be possibly wrong with the above code and why is this giving an error ?

I setup a strongly typed dataset using the DatasetDesigner in VB2010. I am using the TableAdapter.Insert method to add data to an Access table. Before the data is inserted I need to validate the data using the DataTable RowChanging event.
How can I get the DataTable RowChanging event to fire when using the TableAdapter.Insert method?
Here is an excerpt of code I have so far:
When the Insert method runs, it does not fire the datatable RowChanging or NewRow events.
Imports System.IO
Imports System.Data.OleDb
Imports System.Data

My idea is to add a entry to the windows context menu "Host File"
Then it will upload it to tinypic.
I assume it would have to be done using httpwebrequest?

I have always used the API for Vb.net from Decaptcher.com and have always sent the Captcha by sending an actual url to them as you see in the code below. Or maybe it uploaded the image anyway to them (I use the Webbrowser Control) [code] But with the current project that I am working on right now I am having to take a screen shot of the captcha image, then save it to my harddrive.I know that through your API Decaptcher allows us to upload the image from our harddrive but I just can't figure out how to use the code to do this. I have tried this but it doesn't work: [code]

Is there a way by using ASPxUploadControl to have an image get uploaded automatically when you click the ok button after browsing and then get shown a preview of said image but only upload the image to the server officially after you click an ok button? I found [URL] which looks like it does the automatic upload but thats about all I've found so far.

I want to be able to kinda like have a timer that will get an image off my Hard Drive, and upload it online, so that all I'd have to do is download the image, even if it's been written over, I want to be able to broadcast an image from my hard drive, using only my IP Address.
127.0.0.1 is my IP Address.8888 is the port.Somthing like if you were to goto http://127.0.0.1:8888/update.html or Update.Jpg If YOU were to go to this address on your machine, you could see the image... Of coarse, it will probably be an image of which I was able to get from Printing my Screen image, and then saving it as like C:Test.Jpg, but the Timer would get my Desktop Image, or Print My Screen and Save it and Overwrite the Test.jpg image on the C Drive... Ya know what I'm talking about?

I want to resize the resolution of an image before uploading it to local storage. Right now it saves the image in its full resolution and I have to manually resize it using width="200" height="200" or a css tag in aspx. I want to reduce the file size of an image before storing it, hence by resizing the image resolution when the user uploads it via button. I've tried using System.Drawing before and setting the int imageHeight and int maxWidth to be resized but couldn't seem to get it to work.
My code so far is:
Protected Sub btn_SavePic_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btn_SavePic.Click
Dim newFileName As String
Dim SqlString As String

I am interested in uploading an image to a file field using httpwebrequest or similar however I am stuck on a few things. Would it be a matter of add the file field and the image I would like to upload as the value? I'm not looking for code, I would like to learn how this can be accomplished.

I want to use the http:[url....API function to upload a picture onto ImageShack and then obtain the image_link. The only problem is, how do you place an image with its file name with the form-data along with the API key? This is what is stumping me in trying to implement the function.By the way, OpenDialog is already implemented to select the file to upload.
Update: I tried adapting the existing code to use the Unified API and it still does not work. If anyone knows what's wrong in the code, just make the modifications... Otherwise,
Imports System.Xml
Imports System.Xml.Serialization
Imports System.Xml.XPath[code]......

I'm uploading an image to url... etc. The trouble is my application stops responding for 5-10 seconds while the image is uploading. I want to use multi-threading to stop it doing that but I'm confused with the whole way to use controls with backgroundworker. [code] I guess its the textbox which is causing the problem.

im trying to write to an sql database. im inserting an image, as well as some other information. I am using the following code which works fine, as long as i do not add an extra column/variable "LOCATION" in to the mix and leave "
'Cmd.Parameters.Add("@LOCATION", OleDb.OleDbType., 3).Value = "testing"
commented out. *this is undesireable as im trying to add extra criteria to be saved like LOCATION.
Try
Dim st As New FileStream("\serverfolder1storage" & "pdftemplate.jpg", FileMode.Open, FileAccess.Read)
Dim mbr As BinaryReader = New BinaryReader(st)
Dim buffer(st.Length) As Byte
[code]....
i am trying to store the location e.g "c:file1.jpg" in the sql db. Can anyone reccomend a solution to this using OLEDB? ideally i need to add approx 4 more variables. e,g
firstname
surname
dob
location
