Problem In Saving Image ????
Mar 27, 2008
Hi
i am using textcopy to store image (named as mypic.jpg) in image column.
But i am getting error :
text or image pointer and timestamp retrieval failed
I guess this is bacause of image size ...
The default image column length is 16. I tried changing it but it's not changing and Books Online shows that the image column can store max upto 2 GB.
I just want to know also how to change that size to say 100kb?????
thanx in advance

Using: Compact Framework 1.0 and SQL Server CE 2.0
i want to save an image to my sql server ce 2.0 database on the device.
In the Compact Framework 1.0 the Image class does not have .FromStream method, and the PictureBox class does not .Save method.
Has anyone done this before in SQL CE 2.0 and CF1.0
Thanks

Hi folks,
I am really hoping there is someone out there with the answer to my problems??
I need to save customer signatures to our SQL DB and then display them on a Crystal Report. The problem is that the client uses Crystal v6. I am saving the image to an Image field using an ADO rs on a VB6 application. It saves fine and will read back fine. Crystal however has a problem and throws an error "Not Supported".(Later versions of Crystal erad the images fine)
Northwind Database has a Table 'Categories' which as images that crystal v6 is able to display. As of yet I have been unable to save images in this format. I have tried .bmp,.jpg ...... I have also tried appendChunk..
All the images on Northwind start with '0x151C2...'
My bmp start with '0xFFD8....'
Any suggestions would be greatly appreciated.

Vb stores an image (bitmap/jpg) in a SQL2000 image field. For somereason it doubles the size by adding 00 for each byte. But sometimes itdoesn't add 00 (0000.0000) but 01 or 20 or ?? and also the byte thatshould be transferd is changed...So SQLImageData = Imagebyte + 00and sometimesSQLImageData = CHANGEDImagebyte + xx.Some example data: (hex notation):A1 => A1 0003 => 03 00-----------91 => 18 2083 => 92 018C => 52 01Could anybody give me an explanation, because I need to know what ishappening, so I can remove te extra bytes added......I have already a image when I remove the extra bytes, but with somewrong data (on the place where things like 8C => 52 01 happen)....Thx,Geronimo

When i click upload image button when my database table has no any row, the selected image is saved(one row saved in table). If i continue and select a different image, i get no error sa if the image has been saved but when i view the images i have been saving, its strange even if i saved 10 records they all contain the first image that i saved. In short only the first image is saved the rest of the rows are just duplicates of the first row. so it basically becomes a table of ten rows but with same data rows(same image). Code is below.
Protected Sub btnupload_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim intLength As Integer
Dim arrContent As Byte()
If FileUpload.PostedFile Is Nothing Then
Lblstatus.Text = "No file specified."
Exit Sub
Else
Dim fileName As String = FileUpload.PostedFile.FileName
Dim ext As String = fileName.Substring(fileName.LastIndexOf("."))
ext = ext.ToLower
Dim imgType = FileUpload.PostedFile.ContentType
If ext = ".jpg" Then
ElseIf ext = ".bmp" Then
ElseIf ext = ".gif" Then
ElseIf ext = "jpg" Then
ElseIf ext = "bmp" Then
ElseIf ext = "gif" Then
Else
Lblstatus.Text = "Only gif, bmp, or jpg format files supported."
Exit Sub
End If
intLength = Convert.ToInt32(FileUpload.PostedFile.InputStream.Length)
ReDim arrContent(intLength)
FileUpload.PostedFile.InputStream.Read(arrContent, 0, intLength)
If Doc2SQLServer(txtTitle.Text.Trim, arrContent, intLength, imgType) = True Then
Lblstatus.Text = "Image uploaded successfully."
Else
Lblstatus.Text = "An error occured while uploading Image... Please try again."
End If
End If
End Sub
Protected Function Doc2SQLServer(ByVal title As String, ByVal Content As Byte(), ByVal Length As Integer, ByVal strType As String) As Boolean
Try
Dim cnn As Data.SqlClient.SqlConnection
Dim cmd As Data.SqlClient.SqlCommand
Dim param As Data.SqlClient.SqlParameter
Dim strSQL As String
strSQL = "Insert Into Images(imgData,imgTitle,imgType,imgLength,incident_id) Values(@content,@title,@type,@length,@incident_id)"
Dim connString As String = "Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|safetydata.mdf;Integrated Security=True;User Instance=True"
cnn = New Data.SqlClient.SqlConnection(connString)

Hi Guys,
I am trying to automate a basic task using SQL Server 2005 Express.
Currently I have a query script that I run and then save the results as a CSV file. I need to do this on a daily basis and so I am looking to find out how best to go about this. There are a multitude of third party tools that claim to be able to do this - can anyone recommend this or enlighten me of the best way to set up this automation.
All ideas gratefully received!

I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

Ok, the problem is that , i have a field called "Attach" in sql of type image, when selecting it , the field is getting data of type BYTE(). which am being unable to display them on an Image on the panel.
using the following vb.net code:
'Dim sel2 As String
'Dim myCom As SqlCommand
'Dim conn As New SqlConnection
'Dim drr As SqlDataReader
'Dim image As System.Drawing.Image
'sel2 = "select * from attach where att_desc = '" & DropDownList1.SelectedItem().Text & "' and doc_code = " & w_doc_code & " and subcode = " & w_doc_subcode & " and doc_num= " & w_doc_num & " "
'conn.ConnectionString = ("server=developer01;uid=sa;password=aims;database=DVPSOC;timeout=45")
'myCom = New SqlCommand(sel2, conn)
'conn.Open()
'drr = myCom.ExecuteReader()
'If drr.Read Then
' Me.ImageMap1.ImageUrl = drr.Item("attach")
'End If
'conn.Close()
Am getting an exeption on the following line Me.ImageMap1.ImageUrl = drr.Item("attach")
saying: Conversion from type 'Byte()' to type 'String' is not valid.
knowing that i tried converting using ToString but it's not getting any output then.
thanks for your help.

I have learned lots of informative thing from your forums. I have little problem regarding “Display image from SQL Server on ASP.NET� I have done it and image display on my page from SQL Server. I have cleared you here I have adopt two different methods which are following for displaying picture.
1.Response.BinaryWrite(rd("picture"))
2.image.Save(Response.OutputStream, ImageFormat.Jpeg)
but in both above methods I have faced little problem when image display on my page all other information can not display and I also want to display picture on my specific location on the page. My second question is can use any web control like “Image1� to display image from SQL Server where my pictures are stored.
Hope you will help me.
Thanks and regards

In my asp.net application I have a local report with an image control in thedetail row of the table and the Value attribute set as="File://" & Fields!FQPhotoFileName.ValueThe first row in the table always shows the wrong image and it's always thesame wrong image. The problem is there even when I change the sort order orthe criteria for the underlying dataset. For example, I ran a small testthat populated the dataset with 2 rows and 2 images. When I sort by anycolumn (e.g. ID) in ascending ascending order the ID=1 row (the 1st row)shows the wrong image and the ID=2 row shows the correct image. When I rerunthe report sorting in descending order the ID=2 row (which is now the 1strow) shows the wrong image and the ID=1 shows the correct image.Any suggestions?

I am currently migrating my application from Access to SQL. It looks like it's working good but one thing I cannot understand is why when I have created a varchar(40) field and after I insert a field that is less then 40 characters long, the rest of the string is filled with the leading spaces. I have also create an nchar(40) that did not solve it ether. For example: the text is "Hello World". The text is 11 characters long but the data saved to the table is: "Hello Wolrd" + 29 spaces. Am I doing something wrong?Thanks for your help in advance.

When I open a DTS package, save it as a bas file, make changes, close the package and save it when prompted, where are my changes saved?
The answer appears to be nowhere. When I reopen the package it's back to it's original setup. When I check the bas file it's as it was when I originally saved it.
Any ideas? Like where my mornings work is gone?

Hi, all.This might be a silly question... but I am very new to programming inSQL so please bear with me :)So. I'm using MS SQL Server 2005 Management Studio Express. I have atable that was created via an existing .sql file. Included were abunch of stored procedures. I went in to re-format these procedures.(They were written in haste by another programmer. It is my task to goback and improve their readabilities.) However, I am having difficultyfiguring out how to save the changes to these stored procedures. Thusfar, I have been individually saving each stored procedure in itsown .sql file. This is obviously not the way to go... but it's atemporary solution (so as not to lose the changes I have made todozens of procedures).Can someone please explain to me how I commit these changes to thedatabase?Thanks,Allie

Good day
Using vb 2005 express I have my grid veiw on the form and a icon to click to save my work.
But is there a passage of code I can write to pop up a message box to remind me to save my work when I close my form. Similar to ms office forms when you close they ask you if you want to save any changes.
Thanks

Is it better to have users that upload pictures have them saved to SQL server or to a folder? I have a site where users enter things that they own (and each item has a unique id) and now I would like to add the functionality to add a picture. I am sure I should use the fileUpload control, but should this save to a folder created for each user or to the SQL record itself? Or possibly a separate SQL table just for pictures?Thanks for the help.

Hello Im having a little problem getting some values from a database.....
What I need is to get the value of the keyfield of the last entry introduced, I know how to to do the SQL statement for this, the problem is that i dont know how to save this value in a variable. I need to save this value in a variable in the session object or in a hidden field, and then use this variable in another different page. That's way i need to save this ID value, later in the other page I introduce data in a different table and one of the fields has to be this ID value which I have as a foreign key in the table so I need to use the same value in all the rows i introduce(Id value).
If you know how to accomplish this let me know, many thanks, Sergio
