How can I create a web form with image map and upload, like firstname, lastname , phone and address with file upload and image map and submit button. How do I create the parameter and connection to database.
View 1 RepliesI'm not sure where this should go (I don't know whether it's a database problem, or a code problem), but I think it's a code problem, so I'm posting here.
I'm working with a database that is storing images (actually, it's a modified version of the AdventureWorks database from Microsoft), and I'm creating a form that will let you upload a file. I've got a business object based on the table that I'm using (Production.ProductPhoto) and I'm using two stored procedures to either get (Production.ProductPhoto_Get) or add (Production.ProductPhoto_Add) an entry from/to the table. The image is being stored as a varbinary field in the database, and a Byte() in my business object.
The problem I'm having is that when I'm adding a new entry and uploading a file, the length of the file uploaded is correct (so I assume everything is going smoothly), and it gets passed along to my ProductPhotoProvider DAL class where I create a DbCommand and add the parameters for my stored procedure. The information is all added to the database successfully, and I'm returned the identity of the new entry as expected -- however, when I try to read this image back, it seems that the length is 1. I've put in break points and stepped through everything, and I don't know what's going on.
I think that I know my ProductPhotoProvider class is at least reading things correctly -- I can display other images from the database (that came with the database, that is) just fine. Mine just all come back with a length of 1.
I'm just hoping someone knows what the hell I'm talking about; I have a lot of programming experience, but this is my first major venture into ASP.NET. I have no idea which parts of my code are relevant, so I'll just post my Add and Lookup functions for now?!
[Code]....
My ProductPhotoProvider class is based off of an abstract class called AbstractDALProvider (which I can also provide if needed). I can provide the rest of my project, if needed, too.
Oh, and for good measure: I was told that when you used to store images in Microsoft Access, there was some sort of problem when retrieving the data and you'd have to strip the first 72 bytes of data from it, or something. I can only assume that this is not a problem here, because I have no problem displaying other photos that were not created by me.
I have a problem tried for a couple of days and can not find any solutions. I have a ImageUpload form and VB code behind (Below) and when I execute it give me theis error

I'm having an image in my page displayed to clients form a folder under same apllication folder,I also have a form in the same page that accepts an image file to be uploaded. The image that is uploaded via this form should take the place of the image that's displayed in the page with the name newly givven at runtime. The new image should be uploaded in the same directory with the new name provided, which means it overwrites the previous image.

View 1 RepliesI have to insert default image into databse..when no image is selected from fileupload control.. Here is code...not working for default image...
if (FileUpload1.HasFile){string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(Server.MapPath("~/UPLOADEDFILES/" + FileName));
feedBack.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, FileName));
} else {
string filename="~/images/"+ "sun.gif";filename.pPropertyImage = filename;FileUpload1.SaveAs(MapPath(filename));}
We have a scenario where we would like to allow our users to upload images to the site. We are running on ASP.Net. A quick search did not result in anything good. It would be great if the control is free/open source but we do not mind paying a little bit.
View 1 RepliesI'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

I have tried various techniques that some seemed to have outlined and so far none of them have worked. I have a situation where the Page_Load() needs to build a set of <input id=<dynamic name'>> that are build dynamically inside a <ul>. The form gets created fine but when I click the button and look at the results returned to the server I cannot seem to find the input values. Is there a defined way of accomplishing this?

How can i upload a file using fileupload control from an asp.net form and store it in systems harddisk and just have a tag of that file in sql database... and also how to retirve that file for download.
View 8 RepliesI'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:
"Age" "Duration" "Period of Duration" "etc..."
Last30Days
1-5 Months ago
6-11 Months ago
Age
Age
Age
etc.
So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.

I am able to upload pictures to the database and display them(using handler & listview), but when I go to create a new album it shows the previously uploaded pictures of the first one.
