I have a form that has 2 sections.
Each section has a textbox/ fileupload control and a button.

I want to add a RequiredFieldValidator for the textbox/ fileupload control and want to activate the validator only to the controls in that section, when the button in that section is clicked.

When Button1 is clicked, then RequiredFieldValidator for textbox1 in section1 should get activated and not the RequiredFieldValidator of the control textbox2.

How do I do it?

Thanks
Krutika

If this is in .NET 2.0, you can use the ValidationGroup property. If not, you will have to do you validation on the server side.

asp:Table vs. an HTML table

What the advantages of one over the other when I'm programing a page? I understand that when the page is run it will change all the asp:Table, asp:TableRow, and asp:TableCell into their HTML counterparts so why not just use the counter parts? I understand most of the other asp:components and why they are better but I can't find a reason for asp:Table.

So far I've noticed:
I can't use Height and Width on the CSS versions
I can't edit my cell contents in Design View
I can't set a background image on the fly (I currently am using a CSS file but it seems a waste since all it has in it is repeating backgrounds and each class is only used once)

Please tell me what I'm missing, what advantages I could gain, or if I should just start using the basic HTML table.

Thanks for any help.

The advantage is runat="server", which of course treats it as any other serve control to use, and abuse, as necessary with your code behide.

I don't understand the problems you are having with CSS, it is applied on the client side after the control has been rendered to appropriate HTML.

How to create a file watcher window service to look in a folder for new file??

Goal of the filewatcher window service: to look in a folder named ‘Watcher’ for a particular type of file. Whenever a new file arrives in the watcher folder, service should pick up the file, read contents, then delete the file from the folder and move it in another folder named ‘Processed’.
I am using filewatcher’s oncreated event for this. Whenever a file arrives, the oncreated event is fired. The problem I am facing is that the service is not able to read the file. The exception received is: The process cannot access the file
'\\WATCHER\abc_1959537.xml' because it is being used by another process. I tried to manually paste the files in ‘Watcher’ folder as well as in automated manner by a console application the result is same. Please help!
I m using this code:

private void filewatcher1_Created(object sender, System.IO.FileSystemEventArgs e)
{
log.Info("file found :" + e.FullPath);
try
{
//Get the path of the recently arrived file
string fpath = e.FullPath;

//Get the xml string from file
FileStream objStream= new FileStream(filename, FileMode.Open,FileAccess.Read,FileShare.Read);
StreamReader sr = new StreamReader(objStream);
string tempstring = "";
string filestring = "";
while ((tempstring = sr.ReadLine()) != null)
{
filestring += tempstring;

}
sr.Close();
sr.Dispose();

//Move file in a new folder

FileInfo fi = new FileInfo(e.FullPath);
fi.Directory.CreateSubdirectory("updated");
File.Copy(e.FullPath, fi.DirectoryName + "\\Updated\\" + fi.Name, true);
fi.Delete();

log.Info("File Sucessfuly moved: " + fpath);
}
catch (Exception ex)
{
log.Info(ex.Message);
}

}

try wrapping the part that you open your stream reader in a using block,
Check out here

Also reading your code, I'm not quite sure where you the variable FileName get's it's values from?

the code is quite messy could do with some tidying up, tyhat way you could probably find the bug!

I tried something like this and it works fine for me?

 StringBuilder sbXML = new StringBuilder();<br />
                string fPath = e.FullPath.ToString();<br />
                using(FileStream fStream = new FileStream(fPath,FileMode.Open,FileAccess.Read,FileShare.Read))<br />
                using(StreamReader sr = new StreamReader(fStream))<br />
                {<br />
                    while( sr.Peek() > -1)<br />
                    {<br />
                        sbXML.Append(sr.ReadLine());<br />
                    }<br />
                }<br />
<br />
                FileInfo fi = new FileInfo(e.FullPath);<br />
                fi.Directory.CreateSubdirectory("updated");<br />
                File.Copy(e.FullPath, fi.DirectoryName + "\\Updated\\" + fi.Name, true);<br />
                fi.Delete();<br />
<br />

Thanks for your suggestions; I tried with your code also but facing same problem. Sometime the service successes in reading, moving and deleting file but sometime it gives error "process cannot access the file 'abc_4726137.xml' because it is being used by another process".

sorry I was busy today!

Instead of

 FileInfo fi = new FileInfo(e.FullPath);<br />
fi.Directory.CreateSubdirectory("updated");<br />
File.Copy(e.FullPath, fi.DirectoryName + "\\Updated\\" + fi.Name, true);<br />
fi.Delete();<br />

Why don't you try File.Move ?

         e.Item.Attributes("onclick") = "javascript:this.bgColor='blue';"
     End If

Have a happy programming... Wink | ;)

I think you should first of all, STOP TYPING UPPERCASE!!! This doesn't make us reply or type quicker!! Have you read some articles about sending sms messages from a computer? You need an SMS Server kind of construction which sends the messages via a modem line to you phone provider, which handles the message and actually sends the message in the air.

I think you should be able to send the message to you cellphone, en let it send the message but have no experience using that solution. It might also depend on the cellphone you're using (i can't send sms messages through my computer having a smartphone)

You should consider one of those SMS servers Wink | ;-)

Web service, adding a web reference to a web service over the internet

steve_rm28-Dec-06 1:14

Hello,

I have developed a Web service and a PDA application. The Web service and SQL database are on the same server.

The client will use the PDA application and access the web service to get data on customers.

The web service, PDA application, and SQL server have all be developed and are working using the localhost, local network. By adding the web reference.

My problem is when I want to add the web reference from the Internet. This is because the clients will be on the road or at a clients office. And will need access to their data.

I have added the web reference in the normal way. Right click | Add reference. From the Internet I can access the server and add the web reference. However, the problem is that wsdl file is never included.

Some tests i have done.
Test 1
Accessing the web service when adding the web reference from the local computer, or local network. The following files are included: reference.map, service.disco, service.wsdl.

Test 2
Access the web service from the Internet when adding the web reference.
The following files are included: reference.map, service.disco. THERE IS NO service.wsdl.

Test 3
If I access the web service directly from a browser, I can see the list of web methods and descriptions.

Test 4
If i acess the web service from the Internet when adding the web reference like the following: http://MyServer/service.asmx?wsdl. The only file that is included is the service.wsdl.

I have created another simple web service that just displays the hello world. This has the same problem as above, but maybe you can use it for testing my web service.

http://cf01.no-ip.com:8000/webservice1/service.asmx

However, the above link works, but sometimes is offline.

If you can give me any advice or help with this problem I would be most grateful,

Thanks in advance,

Steve

Encrypting files on server side

I'm working on an application where clients can upload files, but those files should be stored encrypted.

I am using a propietary uploader quite similar to asp.net uploader, and I was trying to encrypt the file to another folder and delete the original one.

To do the encryption tried using Rijndael as seen on: http://www.codeproject.com/dotnet/EncryptFile.asp[^]

The problem is that this article is reffered to a local application, so when I use System.IO.FileStream type on an URI address, it doesn't work.

I've been trying to use System.Net.WebClient namespace whithout much success.

Any clue on how I can proceed?

Thanks

Why don't you upload the file to the server and encrypt the file server side once uploaded?

That's what I meant.

I couldn't encrypt the file using URI file paths

Anyway I've solved the problem now. I use the real file path from inside the server, so there is no problem using fileStream.

That's exactly the way to do it, because else you would access the file via IIS which probably leaves you with lots of problems and most of all, not enough rights to manipulate the file.
