Is it possible to limit the asp.net fileupload dialog to view only XML files?(Filer, .xml only)
Note: Not to check whether the extension is .xml, but to actually only let the user view xml files in the dialog.
I am trying to find a way of setting a default image(e.g. file path) for the FileUpload control so that a default image can be used if a user did NOT choose to upload an image.

I have created an ashx handler to render image thumbnails from images in a mysql database. If a file name is passed through querystring, the content disposition filename is set (when user clicks "save as..." the filename appears). The images appear properly and the filename appears when user selects "save as..." but the filetype is listed as unknown and the file that downloads has no type. I have tried adding ".jpg" to the end of the filename in content disposition for lack of anything else to try, but this made every image download as untitled.bmp.

I am working on a website that draws fractals on the screen. It was my intention that with a right mouse click the picture could be saved to the visitor's computer. But that I get an error message "filetype blocked".The file is called test.jpg and is drawn to the screen as a bitmap. Could anybody tell me how to 'unblock' the right mouse click so that a visitor can save a picture he or she likes?Maybe it would be possible to let people download the image? But how would that work?

I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
I have develop a web application. I have put my web application in my server and user can access from any location.
My server regional and setting is English (US). Now my problem is
1) When user access to my system and his pc setting is English (UK), it will prompt and error
and after i debug i suspect it is because of Datetime conflict (dd/MM/yyyy and MM/dd/yyyy)
2) I cannot fix or limit my user to setting his/her pc regional setting to UK
So what can i do in my web application solve this issue?
(Can i write any code in my client side (.aspx) to convert or do standardization to US)
I would like to set a value:
[code]....
...where [HERE] is the placeholder for my value, from my code behind in ASP.NET before the page is rendered. I generate a guid, and I need that apart of the script on the page.
I'm working with ASP.Net web services and am having a problem with a long-running process that takes about 5 minutes to complete, and it's timing out. To fix this, I was able to set the executionTimeout on the server's web.config to 10 minutes, and then set the .Timeout property on the Web Service object to approximately 9 minutes. Now, I'm worried that this may possibly cause some other web service calls to sit there for 10 minutes before they time out rather than the previous 90-100 seconds. I know the default on the client side is 100 seconds, but wasn't sure if updating the server's timeout setting would affect this.
Bottom line is - Is it safe to update the server's timeout setting to a long amount like 10 minutes, and rely on the default timeout on the client, or could this end up causing some problems?

While postback the filename path is gone from the file upload control(as expected/ or Default property).
I am converting the file to byte array, to store in the database from file upload control.
How can i retain the value or Is there any way to solve this issue.

Or it is possible to set the value to file upload control during postback ?
I need the full client path of the file on the server side so that I can use a library to get text from the document. It appears that due to security reasons, IE8 replaces the file name with
C:fakepathdocument.doc
Is there a way to get the full path to the file name?
I have a detailsview which uploads 4 files and uses the objectcontainerdatasource. However, what I would like to do is once I got my files from the fileupload object is to cast it to FileInfo type.At the moment I can get hold of the files via detailsview but this is where I need help; as I have four files to upload, I want to save them to either an array, collection or list of type FileUpload or FileInfo (preferably FileInfo) along with two other properties and then to pass these values to a method that saves these files to a temporary location. This brings me to my next problem. In the method that saves the files to a temporay location, whilst I can do this with FileUpload, I want to return from this method the new file path location as a FileInfo type in order to use this in another method.
View 1 RepliesI need to provide a way for the user to specify a path to a file on his machine on my intranet web application, and the ASP:FileUpload control provides a nice dialog to do that, however it also transfers the contents of the file over. Since I only need the file path and not the contents, is there another way to achieve this?
