Your answer is absolutely right. If I save the file to one of the folders under the project, it works with IIS.

So I wonder if there is any way to write directly to another location like I did (Configure IIS for example) because when I searched information, some people say that there is a way by adding this line in web.config file between tag <system.web> and </system.web>:

<identity impersonate="true"/>

I tried, but it did not work.

Thanks for your help,

What abt this code..!

protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button6_Click(object sender, EventArgs e)
    {
        FileUpload1.SaveAs("D:\\a.txt");  <big><----</big>

That code placed in default.aspx.cs file is used to save a file whose path is got from FileUpload1 Control to D:\a.txt (Actually, it saves and change the original file's name into a.txt).

If I modify it as following, it works:

protected void Button6_Click(object sender, EventArgs e)
    {
        FileUpload1.SaveAs(Server.Map("~")+@"\a.txt");  <----
    }

But I do want it to do directly on D: Drive (or another Drive, not C: Drive)

Thanks,

Yes, I tried and it worked, but this approach is not exactly what I want. If the path is got from Server.Map("~"), I just only work with C: Drive because wwwroot folder of IIS is only placed on C:Drive. I want to work with D: Drive instead.

Thanks,

Yes, I tried the code above and that is the approach I want to do. Unfortunately, it threw an error like the question of this topic.

This is most frequently asked question. There is a search box on the right top corner. You will find plenty of answers if you use that.

To answer the question, you need keep a flag in the database which will be set when user logs in and unset when logs out. When a user logs in, check the status of this flag and if it is set, say that user has logged already. This method is not fully foolproof. A common problem of this approach is your flag will not reset if user closes the browser without logging out.

Hooking JS method on window close and doing AJAX request to reset the flag is one possible option. But since JS can be turned off at the client side, this method is not reliable. A better approach is to record the last activity time of the user and a database job resets the flag if current time - last activity time is greater than session expiry limit.

A combination of all these methods will work well.

Whenever there's a postback (ie: the user submits a form etc, clicks a button, whatever), simply call a function that updates a field in your user table with the current date/time.

I meant exactly what Damian said. This will allow you to identify how long a user is inactive and reset the flag if he is inactive for long time.

I have a file upload control in my application. The user can upload a file starting with alphabets as well as numerals. However, while uploading a file with numbers ,it is giving error. I have the following validation expression:

ValidationExpression="[a-zA-Z\\].*(.txt|.csv|.CSV)$"

How can I include the validation for numbers also? I tried 0-9 as below , but it didn' worked.
[a-zA-Z0-9\\]

Please help

IMO, you only have to test for supported extensions. Work with Path.GetExtension[^] method. You don't need to any regular expression.

How can I use a static class that is placed in another folder

Re: How can I use a static class that is placed in another folder

2-Nov-09 13:25

Hi
I don't know how I can use a static class, that is placed in another folder from where I'm calling it.

I have the code below in default.aspx.cs, witch is placed under the folders Test1/Test2
(\WebSite12\Test1\Test2\Default.aspx.cs)

public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            SqlConnection s = Databas.con;
        }
    }

The class, Databas.cs is placed in the root of the website. I get the error The name 'Databas' does not exist in the current context. I have the same problem with the global.asax, whitch is also placed in the root.

Please Help

The root is the wrong place to put it, in every way. There's a folder for your application code, it has to go in there.

Why would you want to return a SQLConnection into the presentation layer ?

Hi, thanks for your answer

I put the Databas.cs in the folder App_Code, but I couldn't use it anyway. Is there something else I have to do, then writing SqlConnection s= Databas.con.
I have it like this because I don't want to write the connection string for every page.
I have trouble with using the global.asax also, should that file also be placed in App_Code. But as I said I can't use it anyway.

Please Help
