Create a hidden field in your page and use that to access the values in the code behind.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

Hello all
I have a web site that includes ftpupload control.
Now this is my question: when others send files and pictures for me, How can I access them?
Do they goes to my internet host and I should Download them??? or they go to my hard drive directly and I shouldn't download them???
IS THERE ANYONE TO LINK ME TO A COMPLETE ARTICLE???
THANKS HIM...

Well, the answer is pretty obvious. Either you host your site locally, or your uploads end up on your server, and you have to download them from there.

Do you mean how to access the FTP site? Just download the files using FTP and then see it.
If the server which has FTP site is your own computer, then you can see it inside your FTP site directory.

OHHH!
Files that will send for me may be more than 600mb. with dial-up connection HOW CAN I DOWNLOAD ALL OF THEM
|
|
|
|
|
But without downloading how could you get the files?
You can list the files using FTP list command but that will also list files that are corrupted during uploading.

Hello,
I think this is my first post here. But I've already used a lot of your codes here! Thanks a lot for them! 
Now it's my turn to ask a question 
Is it possible to get the serial number of the motherboard via ASP.NET? This would me interesting to send the license key of my software automatically.
If this is possible, can someone give me an exaple?
Thanks a lot!

This information was very helpfull. But, if you have time to make it, can you make a class to do this?

About which class you are talking about ?
|
|
|
|

I think he wants you to write one ActiveX / Plugin which will get motherboard serial no of the client. 
|
|
|
|

If you can't do your own work, you should advertise in the job section of the site and pay the person you expect to do it for you. This will also give you rights to expect the code to do exactly what you want, and to ask for changes if you need them.

I dont think its a good idea to use any external ActiveX / browser plugin. More you add this to your site, less the amount of users will visit your site.
|
|
|
|
|
I don't think ActiveX is a big problem? But my idea has some other problems. Just like this one: of they buy on another pc the license will not be accepted...
Thanks a lot for your help! I'll search another method for web-based registering.

From the function set value to some hidden variable, then access from codebehind !!
|
|
|
|

/////following way i m assigning to hidden field in javascript
function Check_Wrong_AnsString(args)
{
if (AnsString.length < 1)
{
alert('Can not be blank');
document.getElementById("ctl00_cnPlaHolaaa_Hidden_WrongAns").value = "false";
return;
}
}
////////aspx file
<asp:HiddenField id="Hidden_WrongAns" runat="server" value="true"/>
///////this is my codebehind file
ClientScript.RegisterStartupScript(GetType(), "Check_Wrong_AnsString", "Check_Wrong_AnsString('" + txtWrongAns1.Text.Trim() + "');", true);
string hh = Hidden_WrongAns.Value.ToString();
Response.Write(hh);
//////////but it writes "true" to browser (the default value we supplied at declaration of hidden field)
it should write "false" if function returns false.
please tell me if i have done wrong coding
thanks

This is your server side control. You need to first get "ClientID"
var HClientID="<%=Hidden_WrongAns.ClientID%>";
var hidID=document.getElementById(HClientID).value = "false";

I dont know, what you are doing with getelementId ???
Try this :
.cs file code ::
protected void Button1_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(GetType(), "Check_Wrong_AnsString", "SetServerValue()", true);
Response.Write(HiddenField1.Value);
}
Javascript ::
<script language="javascript">
var HClientID="<%=HiddenField1.ClientID%>";
function SetServerValue(args)
{
var hidID=document.getElementById(HClientID).value = "false";
}
</script>
ASPX :
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
<asp:HiddenField ID="HiddenField1" runat="server" />
Try and run this. This working fine !!
Hope this will help you. Let me know if u have any more issue !!
