My requirement is that i upload an excel file then i need to validate that data.
1. Uploading file using using upload control saving binary in SqlServer
2. Then i am creating file from binary data on Sql Server using below command and then using OPENROWSET to dump data to Sql table
3. Then reading Sql Table row wise and validating data.
Alter Procedure spUploadExcelFile
Declare @VarBin varbinary(max)
Declare @FileName varchar(100)
DECLARE @sql nvarchar(MAX)
DECLARE @errMsg nvarchar(MAX)
DECLARE @ObjectReturn INT
DECLARE @ErrorSource VARCHAR(255)
DECLARE @ErrorDesc VARCHAR(255)
DECLARE @ObjectToken INT
Select @VarBin = Content , @FileName = [FileName] from MultilangBinaryData Where PKID = @PKID
SET @FileName = 'C:\' + @FileName
EXEC sp_OACreate 'ADODB.Stream' @ObjectToken OUTPUT
EXEC sp_OASetProperty @ObjectToken, 'Type', 1
EXEC sp_OAMethod @ObjectToken, 'Open'
EXEC sp_OAMethod @ObjectToken, 'Write', NULL, @VarBin
EXEC sp_OAMethod @ObjectToken, 'SaveToFile', NULL, @FileName, 2
EXEC sp_OAMethod @ObjectToken, 'Close'
EXEC sp_OADestroy @ObjectToken
SET @sql = 'INSERT INTO dbo.UserBulkData SELECT 0,NULL,'+ @BatchI
Is it possible to convert a datatable into binary data and save it into on a binary field on database?
I'm using the following code to upload images, pdf files, word files and excel to a sql table as binary data. However, I can only figure out how to display the images but am clueless about the other type of files. What adjustments do I need to make so that with a button click I can access the other files? 't By the way, I'm using an image control to display the binary data and I'm aware that that will only work to display images, I just don't how to access all the other types of files once uploaded. Thanks
Partial Class Uploads_UReceipts
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Request.QueryString("ImageID") IsNot Nothing Then
Dim strQuery As String = "select Name, ContentType, Data from tblFiles where id=@id"
Dim cmd As SqlCommand = New SqlCommand(strQuery)
I've created 2 web user controls. A = User control that displays an image, and B is the user control that hosts A. I'm trying to stream an array of bytes to A, but it seems like the Response.BinaryWrite method completely overwrites any heirachial controls (I can't see any of B's other controls besides the image).
How do I get A to just display the image from the byte stream? It doesn't come from a database, it's an image I created on the fly.
public void UpdateImage(byte imgbytes)
Response.ContentType = "image/jpg";
Hi folks, I would appreciate any help or guidance on this topic:
How can I receive binary data (specifically an ogg audio file) using a WCF4 service?
The general idea is to define and host a WCF service inside IIS that returns an audio file (ogg file)
I have read some info related with using ByteStreamMessageEncodingBindingElement class to achieve this, also I read some topic related on using MTOM to attach a binary file. It seems that it can be several ways or approaches to achieve this.
So any guidance on the themes and/or examples for the better way to solve this point would be very appreciated.
Thanks in advance.
one of the fields is defined as datatype:image, Length:16.
when I am in SQL management studio and do a select for this one column
I am going through the ASP.NET tutorials and my questions is how do you assign an image to a byte array. Because the example in the tutorial is getting rid of an OLE Header. My Database images, does not have an OLE Header. So how do you augment this code to work for my situation:
protected void Page_Load(object sender, EventArgs e)
int categoryID = Convert.ToInt32(Request.QueryString["CategoryID"]);
// Get information about the specified category
CategoriesBLL categoryAPI = new CategoriesBLL();
Northwind.CategoriesDataTable categories = categoryAPI.GetCategoryWithBinaryDataByCategoryID(categoryID);
Northwind.CategoriesRow category = categories;
// Output HTTP headers providing information about the binary data
Response.ContentType = "image/bmp";
// Output the binary data
// But first we need to strip out the OLE header
const int OleHeaderLength = 78;
int strippedImageLength = category.Picture.Length - OleHeaderLength;
byte strippedImageData = new byte[strippedImageLength];
Array.Copy(category.Picture, OleHeaderLength, strippedImageData, 0, strippedImageLength); Response.BinaryWrite(strippedImageData);
I have an ASP.NET app that writes binary data to a SQL database. It worked fine using SQL Express, but does not ever write the data using SQL Server 2008 R2. SQL Profiler shows the binary data in the UPDATE query, but nothing happens... no errors, no data saved. Does anyone know what I'm missing? Other data types work fine.
My data type is VarBinary(MAX)...
After I inserted a row in my Database (row 27) I started getting this error when I try to insert, update or delete the record in the database.
I've searched about the error on google and it says that I should have a field that crossed the limit of characters.
I have only the autoincrement field, two varchar fields and a text field, neither one of the varchar fields crossed the limit, they arent even close. I found in google that one solution would be turn the field that is having problems in a text field, but the only field that actually can be causing the problem already is of the text type.
The exact error I get on VS 2005 when trying to change something in the row 27 is:
"No row was updated.
The data in row 27 was not committed.Error Source: .Net SqlClient Data Provider.Error Message: String or binary data would be truncated.The statement has been terminated.
Corret the errors and retry or press ESC to cancel the change(s)."
I need some help guyz, see ya, hugs.
