I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I'm trying to server an exe to Firefox from an aspx page. The aspx page handles the headers and the page is launched by our Flex GUI. Flex correctly launches the link for all browsers (including Firefox) so I'm certain that's not the issue.
The problem I'm having is when I try to download the file from within Firefox, FF downloads the file fine but it names it "Content". It has no extension and the file name is incorrect. All the other browsers download it with the file name I specified in the aspx page and they all have the .exe extension. I should note that if I rename the "Content" file to "Content.exe" it runs correctly.Below is the code I'm using in my aspx page -
protected void Page_Load(object sender, EventArgs e) {
string fileName = Request.QueryString["file"];
System.IO.FileInfo fileInfo = new System.IO.FileInfo(Server.MapPath(fileName));

I am working on ASP.NET3.5 platform. I have used a file upload control and a asp button to upload a file. Whenever i try to upload a file which contain special characterlike (file#&%.txt) it show crash and give the messeage "Server Error in 'myapplication' Application." A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Files value was detected from the client (filename="...New Text &#.txt"). Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. how can i prevent this crash using javascript at client side?
I am using HTML file control and HTML image control in .aspx page (for uploading image and showing on web page). It is working fine. But I am unable to get that uploaded image file path and file name in .aspx.cs page. And also tell me how to save selected image in MS ACCESS database.
I have 2 aspx pages. A&B. The page B.aspx contains Fileupload and Update button. When I Navigate from A.aspx to B.aspx the fileuploader must automattically select a file in the client machine (say C:TempTestFile.jpg). The Filename (TestFile.jpg) is already exists in our Database.
View 1 RepliesI'm saving a file with the asyncfileupload ajax plugin from the ajax toolkit and when I save it I'm changing the filename (to avoid multiple files with the same name).
After the file is uploaded, the user needs to know what the file has been named so I'm using this javascript code on the onclientuploadcomplete event.
function UploadComplete(sender, args) {
alert(args.get_fileName());
}
This works except it gets the old name, not the new name (which is determined server-side). Is there any way to get it to return the new name rather than the old name? Or any work around to achieve this?
This is my code in the code behind the get the new filename:
string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;
AsyncFileUpload1.SaveAs(strPath);
I would like to ask some help from you guys on how do i do this problem. I'm using asp.net and my problem is on getting the list of filename inside the folder. Is there a function on this? I tried this on console apps there's a function like GetFileName. Hope somebody could help me on this.

View 3 Repliesi have mapped *.xyz extension to my own custom handler in asp.net and can run it on Windows asp.net.
How can I do the same thing on mono (Linux/Apache - ubuntu)?
I have this in my web.config:
<httpHandlers><add path="*.xyz" verb="*" type="MyCustomHandler,...">...
I also added similar things to mod_mono.conf and several other files but still I get http 404 The resource cannot be found.
I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension.
I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension.
First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests?
Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way?
