Loading Uploaded Xml File Into XmlDocument Object (ASP.Net, MVC, C#)
Jul 27, 2010
I'm getting back into coding after a seven year absence. Loving it, but everything is taking me so long!Anyway, I'm trying to upload a file from the browser and then read it into an XmlDocument object on the server. Originally I cracked this by saving the file to disk, reading it into the XmlDocument object and then deleting the file. The only problem was that the delete action was trying to take place before the XmlDocument.Load action had completed
I have ASP.NET form with an upload control for users to post an image. On the server I load that image (using the Bitmap class) and resize it. Is there any danger in doing that when users upload malicious or affected files or will the code just throw an exception at some point and stop the whole process?
I would like to use HTML input file type in my aspx page to allow user to browse for a excel file and then read the content of the excel sheet programmatically.If I want to read the excel sheet I need the full path of the file to connect to the excel sheet using asp.net.I do not understand how can I get the full path of the file.I know I can get the filename using postedFile.FileName property.But I need the full path of the file.

I want to keep the uploaded file name to make it possible to users to download the file under the same name. But how can I implement it? The one option I see is to store each file to folder with unique name (GUID, for example).
public class Template public string Title {get;set;} public string Body {get;set;} xml that is stored in /files/test.xml in a web application (at the root): [code]...
I have a web form that uploads files by <asp:FileUpload> control. It uploads files to any folder on the disk (path to uploads can change in web.config, for example "c:UploadedFiles"). After file has been uploaded I need to show a link on the WebPage to download this file.
How it's possible create a link to this file (or what is another solution) on the web page if my website is in completely different place!?
I need to create a custom web control which will be a part of a class library. This custom web control implements the upload functionality. I have implemented this with a web user control where I have a fixed path to a page in the web project where the upload of files take place and it works just fine.
The created control in this class library is used in the web project. How do I post the uploaded file to a page, say SomeClass.cs, in the class library.
Actually i am trying to storing the uploaded file into database but when i run this codes:
[Code]....
I got this error: " Incorrect syntax near the keyword 'File'.Incorrect syntax near the keyword 'File'. " can anybody tell me why this error came out?I tried toi change my connection string in web config,but it still showing the same error each time i run it in my local.

I was trying to copy file to ftp via in my asp.net application... I did it successfully, however; when I open the copied file it is empty, I checked the properties aswell and its showing 0kb.
I want to upload csv file and import the data into sql. but I cant do the import thing. The file is uploaded but it cannot be imported into sql. This is my code. Hope that someone can tell me what is the problem.
I wanted to customize/Restrict the File Uploader control as follows:
1. To restrict Users to not to upload some type of file like.exe
2. To restrict the user to a specific size limit.
I also wanted to be able to display appropriate messages to the user if the abover restrictions are violated.
Can I use the validations control to achieve the above goals. As I am already using these controls to display appropriate messages to the user in case of wrong/invalid data.
I have made a document uploading page, In which use can upload their document. I am saving three fields in the database,
Document Name [NVarchar] File [Image] DocumentType [NVarchar]
Now, I am able to add records in the database, successfully. Now I want to show it in the gridview, like DocumentName, DocumentType and a link to download the file.
I have tried by retrieving the records and assigning them to the gridview but I am getting only two columns.
I have an ASP.NET FileUpload control, which allows only image type. I used RegularExpressionValidator like below.
<asp:FileUpload ID="fuPhoto" runat="server" TabIndex="40" /> <asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ControlToValidate="fuPhoto" Display="Dynamic" ErrorMessage="* You can only upload .jpg, .gif or .png image types." ValidationExpression="^.*.(jpg|JPG|jpeg|JPEG|gif|GIF|png|PNG)$">* You can only upload .jpg, .gif or .png image types.</asp:RegularExpressionValidator>
This method will only verify the file's extension, not its actual type. Once I receive the file, I want to examine its contents to determine what it really is, in this case image only.
I have a page set up that allows users to upload files to the server, and then uses a database entry to attach the file to a project. When the project opens, I load a gridview with the list of files, and create a hyperlink to the file like this:
Code: Protected Sub gvFiles_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvFiles.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then ' Dim oLinkButton As LinkButton = e.Row.FindControl("lbDescription") Dim oSQL As New clsSQL
[Code] .....
When I try to click on the link, and select Open file, I get the following error:
I notice the type is right here, but on the open screen it isn't:
It says Type compressed Zip Folder for some reason. What I am doing incorrectly?
I know you are all tired of this Linq-to-Sql questions, but I'm barely starting to use it (never used an ORM before) and I've already find some "ugly" things. I'm pretty used to ASP.NET Webforms old school developing, but I want to leave that behind and learn the new stuff (I've just started to read a ASP.NET MVC book and a .NET 3.5/4.0 one). So here's is one thing I didn't like and I couldn't find a good alternative to it.
In most examples of editing a LINQ object I've seen the object is loaded (hitting the db) at first to fill the current values on the form page. Then, the user modify some fields and when the "Save" button is clicked, the object is loaded for second time and then updated. Here's a simplified example of ScottGu NerdDinner site.
As you can see the dinner object is loaded two times for every modification. Unless I'm missing something about LINQ to SQL caching the last queried objects or something like that I don't like getting it twice when it should be retrieved only one time, modified and then comitted back to the database. So again, am I really missing something? Or is it really hitting the database twice (in the example above it won't harm, but there could be cases that getting an object or set of objects could be heavy stuff).
I am writing a simple web page that users can upload an image file. After the file is uploaded, Users can fill up other question in the web page. then users click the submit button to register them and the file is uploaded previously is move to special folder and is saved there. Know i want to delete the uploaded file if the user upload the file but dont click the submit button and close the web page. because i dont need the file uploaded until the user is not registered.I use Session_End event but i dont know why it dont work.
