My apps required me to store upload files into SQL binary fields. And then allow users to retrieve the files and either chose an apps to view them or save on disk. These files can be in diff formats, not just one type.
I have been reading about using the Response.ContentType method and Response.AddHeader method. The issue is the users can upload anykind of documents, ie: MS words, Xcel, JPEG,TIFF.... So at the time of downloading, I have no way of knowing that type it is to put in the Response.ContentType.
Can't I just stream it to the browser, let the download dialog box handle the type selection? as in when you download a file, the dialog box would ask if you want to select an app to open the file or save it on disk. How would I do so ?
Having trouble with a web page and connecting to SQL DB. Basically I have a form view table connected up to a SQLDataSourceControl and what I want displayed in the form is only data that has been assigned to the user that is logged on now. I have a "ViewAll" page, which lists EVERY field, regardless of who it is assigned to, but the "MyTasks" page should only retrieve the data of the current user.
I have two tables in my DB, the "Users" table, with user data (including an ID number) - this is used again in the "Tasks" table as a foreign key called "AssignTo". Therefore if user Joe Bloggs with ID number 5 logs on, whenever someone assigns a task to him, they will select number 5 in the "Task" table, as this relates to his User ID.

View 3 RepliesI am storing image (jpeg) files into SQL server 2005 using MS Access Forms. When I try to read and render it on a webpage using ASP.net and C# code behind, it could not read it.
But if I write the image to SQL server using ASP.NET C# and then read it back using ASP.NET C#, it render the image just fine in the browser.
Does anyone know if Access write the blob is difference than ASP.NET write the blob into SQL server? I am using the same varbinary as my column in the database.
I have image in the image folder and in my oracle database I have a column with the name IMG which has the name of the image like ab.jpg
I have another column with name IMG1 which is storing the whole url like images/ab.jpg
I can see all the values of my database table in my dataset as well including IMG column and IMG1 column
In my aspx file I wrote code
<asp:imagefield dataimageurlfield="IMG"
dataimageurlformatstring = "~/images/ab.jpg"/>
but it is not displaying anything, however aspx page is working fine, it is showing a field but no image and it is blank, same is the case with IMG1 column as well
I have a list of image names stored in a database, along with the id of the property they are associated with. I'd like to be able to display all of the images in a gridview and then allow the user to select the required image.
The problem I'm having is that the gridview is not displaying. I'm pretty sure it's something basic that I've missed, but can't for the life of me see what it is!
My gridview code in my aspx page:
[Code]....
My code behind (propId is the property id):

I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
I'm in the process of developing a survey system. The tables / fields that are related to my question are:
[Code]....
My issues with this way were:
1) The Data Adaptors receive ALL the records from their correspondent tables. Not a good practice, I believe.
2) If, at some point, the survey had no categories, questions or choices under its child records, an error occurs when the page tries to build the Data Relation. With the work flow I had in mind for the system, this is bound to happen becuase all the Data entry pages (Add Category, Add Question, Add Choice) will be displaying the newly-created survey in a similar fashion (at which point, the survey will have no child records and so an error would occur)
How to Update Binary Image on Formview

View 4 RepliesI'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.
