Upload Dilemma For New Records With GUID As Image Name

Jan 18, 2011

For my CMS I want users to be able to upload pictures which connect to a product. This all goes well until someone wants to upload a picture when creating a new record.

The problem here is that every product has a GUID (next to the ProductID (PK)) and will be created when the product is saved for the first time. I'm uploading my images trough a webservice with Uploadify jquery plugin so it's all in an ajax based way. The image uploader however needs to know the GUID to store it in the right directory.

My temporary fix was to just let the user save the product before uploading so the GUID is known but it's not very user friendly and I'm sure there would be a better way but I cannot find a satisfying one myself.

This is the only option which I could come up with which is kinda ok but maybe I'm missing something completely:

Create a GUID without saving the product, so the image can be uploaded and the product with the GUID can be saved afterwards. But what if the user navigates away after uploading? I could maybe create a scheduled task to delete those orphant images

Has anyone dealt with similar scenarios? I'm very interested in your opions about his matter since this functionality will be used in multiple sections in my CMS.

C# - HttpListener Windows Service Vs HttpHandler .aspx Dilemma

Mar 31, 2011

In a Windows Service I implemented an HttpListener that will handle incoming HTTP Requests to a certain port, parse the query string, insert it in database and send a confirmation response. However, the clients said that they were a bit skeptical and asked if the same could have been done via a webpage. Like having an HTTPHandler listen to a certain port. Got me thinking. What would you do in my situation? Go with the HttpListener/Windows Service or HTTPHandler/.aspx?

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.

Valum File Upload - Works In Chrome But Not IE - Image Img = Image.FromStream(Request.InputStream)

Dec 6, 2010

I'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).
