Web Forms :: Write A String To A File On A Server?
Apr 12, 2010
It is possible to upload a file to an account using the below code by specify an existing filepath.
What I wonder is how it instead would be possible to just write a string to this file instead. Like I want to open the file and write the string "Hello" to this file, file1.txt.
How can that be achieved. I beleive I would have to open up a stream of some kind but are not exactly sure how to set that up:
In asp.net mvc project I am using MYSQlMemberShipProvider. Now I want that instead of reading the connection string from web.config file, it will read the connection string from external file every time. So that I am implementing the cutsom mebership provider class, this class inherits the MemberShipProvider class. But the problem is that if I inherits the MemberShipProvider class then I have to impelment all of its method in my cutsom membership provider class, But I want to use all other inbuilt methods of MemeberShip. What can i do. I only want to add the code like below:
public class CustomSqlMembershipProvider :MembershipProvider { public override void Initialize(string name, NameValueCollection configs) { base.Initialize(name, configs); Connectionstring objProducts = // redaing the connection string. } }
But on compiltaion it is giving me the error does not implement inherit abstract member.
I would like to know your libraries recommendations to read and write Excel applications on ASP .NET website. I have tried GemBox and NPOI, because they don't required Excel to be installed on the server, but they have some limitations on handling Excel files that are marked to read only.
I've recently developed a web user control that lists a series of reports. When the user clicks on the report it serves back a CSV file download in the response stream using the following code:
The code initially worked fine in all browsers. Then the client put a requirement to use SSL for the site. As part of this I introduced a global handler to update the protocol from HTTP to HTTPS for all requests as follows:
However, since securing the site using SSL the CSV file downloads no longer work for IE although they do continue to work for Firefox / Chrome / Safari.
Is there something I am missing in the headers that is unique to IE in order for the file response to work correctly?
The message I receive from IE is:
"Internet Explorer cannot download Reports.aspx from .... in ......
Internet Explorer was unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later."
UPDATE:
Here is some example fiddler output coming back from the page request which looks like it's serving correctly. Why doesn't IE understand that it's just been served a file?
HTTP/1.1 200 OK Date: Tue, 09 Nov 2010 14:23:50 GMT Server: Microsoft-IIS/6.0[code].....
I have an ASP.Net (2.0) application on an intranet that impersonates the users Windows login.
It has <identity impersonate="true" /> in the web.config file.
In a couple of places it needs to create a file in the temp folder of the server (a text file in one instance and a Word doc in another instance) before sending the resulting file to the user, after which it is deleted.
It runs into a permission problem, which I assume is because the user that is being impersonated does not have permission to write to the server's hard drive.
How do I overcome this?
I assume it be something along the lines of temporarily running under a different account for the create/read/write/delete temp file parts of code.
how to do this and which account would be the best (easiest) to use. It will be a Windows 2003 server.

If I chose none, it stores data as "Null" If I Query the data as below, I don't get the data has value of "Null" SELECT tabale From type Where type <> STO or type <> ORD I get data that has empty string but not Null.
1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.
2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD
I have a form where users can store some data for archived documents. All documents are ONLY in PDF format.
There are 2 things I would like to do:
1. there is a "file path" text box on the form. I would like to open a "browse file dialog" box when user clicks the textbox and then the user browses for the file (file is on the users local machine) and selects it. The full file path should be saved to the textbox as string (e.g. "c:archive2010document11122011.pdf"). Also I would like to "limit" the file browser dialog to only show PDF format files...
2. add a code behind command to open the file from the saved path+name (see 1.) in the user's default PDF viewer (Acrobat or Foxit)
I have a problem to write a string to a LinkButton that is located inside a GridView1. Now the hiarchy of controls is like this to understand how to Find this control:
TabContainer0 TabPanel5 TabContainer1 TabPanel7 Panel8 GridView1 LinkButton1 So LinkButton1 that we want to write a string to is located in a GridView1 which is located in Panel8 which is located in TabPanel7 that is located in TabContainer1 that is located in TapPanel5 that is located in TabContainer0.
So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?
I am having trouble connecting to a ms sql database on the server. The hosting company said that the .sql file was imported successfully, but when I try to use the 'login' or 'create account' features im getting an error page saying:
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. make sure the user has a local user profile on the computer. The connection will be closed.
I am sure all the connection info is correct so it is really frustrating trying to work the problem. I have listed the connection string in my web.config file to see if anyone can see anything wrong with it.

I'm trying to write the contents of a TextBox to a file but can't seem to find the right method. Whats wrong with this code?
Dim FileName As HtmlGenericControl = TryCast(DetailsView1.FindControl("TextBox2"), HtmlGenericControl) Dim newFilePath As String = Server.MapPath("/myXML/" + FileName.InnerHtml)
If I replace FileName.InnerHtml with "myXML.xml" it works.
