Yeah. It is possible. there is a trick for it.

1. Add one button (let's say btnUpload) and textbox (txtPath) in your page.
2. Add HTML "input=File"
3. Make this "file" control as invisible. (CSS: opacity or alpha )

CSS - Code

<br />
filter:alpha(opacity=50);<br />
-moz-opacity:0.5;<br />
opacity: 0.5;

4. Write a JS function to fire the click event of input "file" control.

function fireFileClick()<br />
{<br />
  var objfile = document.getElementById('myFile');<br />
  objfile.click();<br />
<br />
  var objTextBox = document.getElementById('txtPath');<br />
  objTextBox.value = objfile.value;<br />
}

5. Add this function on click event of button "btnUpload"

<input type="btnUpload" onclick="fireFileClick();" <br />
         value="Upload File" >

That's all..

Please follow the steps that I mentioned. Let me know the result.

Thanks and Regards,

Say what?

The IIS version that you should use is on your Windows disk. You can't install any other version of IIS than the one intended for your version of Windows.

(There is a possibility to hack Windows, so that it's possible to install an IIS version from a different Window version, but if you are doing this, you are pretty much on your own. You can't have found a description of how it's done without seeing the warning that it's totally unsupported, and may make your system instable.)

methhoo wrote:

Eh... How? Are you sure that it's really IIS that you downloaded, and not something completely different? Like a trojan?

methhoo wrote:

Then I wouldn't call it successful...

Session not available in VirtualPathProvider

16-Aug-07 12:04

Hello guys,

I'm struggling a problem now for some days. Hopefully one of you guys can help me out with that.

I wrote my own VirtualPathProvider and VirtualPathFile to make it possible to load different pages from different locations. It works very good. But now I need to load the pages from different locations depending on a value stored in the session. The time when VirtualPathprovider is invoked the Session object is not available or lets say it's available but null.

Now I found out that the session object is filled when the AcquireSessionState event is invoked, but thats to late for me because the action of loading the page already passed. So now I want to create the session by my own before the AcquireSessionState is invoked. But I don't know how to fill the session object by my own.

Does anybody can help me with this problem? Or has anybody a better idea then filling the session object by my own.

Thanks a lot for any input

Oliver

Hi,

Thanks for the input, but I use cookieless sessions.

I tried to retrieve session data from different locations:

HttpContext.Current.Session - null at this time
HttpContext.Current.ApplicationInstance.Session - null at this time as well

I guess thats because the AcquireSessionState is called later on - where the session object is filled.

What I want to do now is to try initialize the Session earlier, but I don't know if it's possible.

Thanks
Oliver

Hi peacefulmember,

I have to apologize. I use cookies without my knowledge Smile | :)

Now that I know that I use cookies I found out that there is a cookie in which the session id is stored. I save now the value which I wanted to store in the session also in the cache with following statement:

<br />
Cache[Session.SessionID + "_MyKey"] = Value;<br />

The difference to just saving it in the session is that the cache is available every time and the cookies are already present at the time I need to get the value. So in my VirtualFile I added following code to retrieve the value again:

<br />
if (HttpContext.Current.Request.Cookies["ASP.NET_SessionId"] != null) {<br />
value = (String)System.Web.Hosting.HostingEnvironment.Cache[HttpContext.Current.Request.Cookies["ASP.NET_SessionId"].Value + "_MyKey"];<br />
}<br />

That solved the problem for me. It's kind of a workaround. I would have preferred the "Session-Solution" but as the Session is not filled that time I have to solve it this way.

Thanks
Oliver

I have user control with some standard HTML tags. On one of my HTML button tag I want to perform a javascript validation (a Hello test function for now).

I cannot figure out how can I trigger this function from with in my user control on this HTML button tag click event or on usecontrol's click event.
Thanks in advance.

Partial Class MyUserControl
    Inherits System.Web.UI.UserControl
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim js As StringBuilder = New StringBuilder()
        js.Append("<script language=JavaScript>")
        js.Append("function Hello() { ")
        js.Append(" alert ('Hello'); }")
        js.Append("</script>")

        If (Not Page.ClientScript.IsStartupScriptRegistered("MyScript")) Then
            Page.ClientScript.RegisterStartupScript(Me.GetType(), "MyScript", js.ToString())
        End If
    End Sub
End Class

The easiest way is to use a custom validator, which can be made to call any function you like.

Since your javascript function is not dynamic, it's better to write in page itself than writing from code behind. Write your javascript function on usercontrol.

Assume you have a button tag like

<input type="button" id="Btn" OnClick="Hello();">

. This will invoke Hello() method when button is clicked.

I do not want to write my javascript in the page itself. Validations are different in the case of different parameters passed to the user control.

What do you mean by that javascript function is not dynamic..How can I make it dynamic, if that can lead me to the functionality that I want? So, far I was thinking my javascript is dynamic as I have it in page_load and it will be written to the page after form tag is rendered on the page side.

Thanks

Well, I have one more question. Like I mentioned based on user control's parameter value I need to perform different client side validation.

I could set parameter of user control (have a property, suggest if there is another better way), but how can I use this property value in Javascript?

Thanks for bearing with me.
