thanx dear. it will definately work but the scenario is a bit problematic
I have a form on which a richtextbox is placed user inputs the data and save it into database. hundreds of records have been saved in this way. now i have to combine these all into a single document. (for each record user is free to use fonts, colors and other rtf formating). now when i joined them all the richtextbox displayed only one record.
now i removed the closing bracket from every record instead of last. it worked but all text is now in black color. i dont know how to preserve the colors in concatenated rtf

Dear Salman Sheikh,
Try using IO.Stream and get the whole document ni a stream, do what ever you want in the stream and save it as rtf.

Dear friends,
I wish to add file path what I get on execution of each for loop with the help of code in it. I wish to add those path (one path at one time) to some kind of array which can store strings and after the whole execution, I want to process the array.
But not able to find any insert method on string arrray or array, it's there with arraylist but not able to put string in its items.
thanks,

you can use an ArrayList or a List<string> to hold strings.
myArrayList.Add(myString)
and
string myString=(string)myArrayList[myIndex]
or
foreach(string str in myArrayList) (doh, that's C# syntax !)

I recommend you buy a beginner book on .NET and read it. Number one lesson in .NET, every thing is an object. Object is the base class that all reference types derive from. So, a string is absolutely an object. There is no reason for the code you posted to give an error.
I recommend moving to .NET 2.0, also, that's VS2005.

then show the relevant code (in PRE tags !) and the compile- or run-time error as is.

ArrayList sucks, real containers did not arrive until .NET 2.0. Having said that, all that's wrong with arraylist is that it's not typesafe,you can put strings in, you just have to cast them back to the string type on the way out

Dear friends,
I have been working on an applicatin in which user has been assign some images. User needs to print all the documents and I have the images full paths with me in code.
I want user to click on a button and get all the images printed.
But there are many small to big problems in it.
How to write the code to print?
I have found the way to use startifo.verb="print", but seems to be not working all the time, especially when the printer is busy.
What to do friends?
Thanks,

Your best bet is to write your own printing code, then you can format the images any way you like as well as taking control of the print queue.

Dear friends,
I have one application installed on each users machine and I have to put watermark on the images I am showing in the application as per what data user enters.
The problem is that for this purpose, I am creating a canvas from the image and then saving that with new name in the same folder. Now,. when the user don't have rights on that server where the images are stored, they are not able to put watermarks.
So, my questin is this:
How to use a particular account to run an application, so that the app has rights but the user don't have to?

Your user has to set that up. If you could make your app run under admin, in code, then the whole login system would be worthless.
Instead, store your files in the application data folder for the current logged in user, all users have access to write there.

You might find it easier to work around this problem. Preferably just give the users rights to write to the images folder (if thats safe). Or have a web service on the server that runs under an account that has the permission to write there - and write your application to upload to the web service. (Theres a lot of potential security vulnerabilities here if you aren't careful).
If those are both out the question then you might have to go for a service on the local machine running as an elevated account, that your application talks to over remoting, and let the server actually perform the upload.

Will try that out. but if any starter guide to webserivces available please provide me with that.

The MSDN is pretty helpful for this one, and Visual Studio makes it pretty easy. There's a few decent guides on MSDN.

What account does it use, with windows application built on vb.net on framework 1.1, when we fetch an image in to picturebox?

Most POP3 mail clients (assuming POP3 is the protocol your using?) keep a log of the items that have been downloaded (read) from the server locally, to my knowledge there is no per article read information kept by the server. See this RFC article for the ins and outs of the POP3 protocol.

Hi
Can u tell me how can i keep log of the items that have been
read.Can you give some hint to me regarding to that.
like some sample code for that.
Thanks.

Rahul,
Please answer the following questions to allow me to help you further:
1. Which protocol are you using to connect to the server? (POP3 / IMAP / Exchange / etc)
2. How are you connecting from your .NET code to the server? Are you using a plugin like Jscapes E-Mail Factory or have you developed your own code to connect to the server?
I cannot provide you with sample code or give direction on how to log message IDs to file unless you give me more info to work with.
To give you a pointer if you are using POP3, all messages on the server have a unique message ID which you will need to use to retrieve or delete a message from the server. I suggest you keep a local list of the message IDs that your app has downloaded. You can then reference that file to see whether the ID is in the list, therefore determining whether the e-mail has been downloaded (read). A simple way of keeping the IDs to start with would be in a text file.

i am using POP3 protocol to connect to server.
i have developed my own code to connect to server.
the code i have used is as follow.
Public Function UserInfo(ByVal uname As String, ByVal emailid As String, ByVal pwd As String, ByVal servername As String) As String<br />
CRLF = "\r\n"<br />
Dim cr As Cursor = Windows.Forms.Cursor.Current<br />
Windows.Forms.Cursor.Current = Cursors.WaitCursor<br />
Server = New TcpClient(servername, 110)<br />
Try<br />
NetStrm = Server.GetStream<br />
RdStrm = New StreamReader(Server.GetStream())<br />
'Status.Items.Add(RdStrm.ReadLine())<br />
msg = RdStrm.ReadLine()<br />
<br />
Data = "USER " + emailid + CRLF<br />
szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray())<br />
NetStrm.Write(szData, 0, szData.Length)<br />
'Status.Items.Add(RdStrm.ReadLine())<br />
<br />
Data = "PASS " + pwd + CRLF<br />
szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray())<br />
NetStrm.Write(szData, 0, szData.Length)<br />
' Status.Items.Add(RdStrm.ReadLine())<br />
<br />
Data = "STAT" + CRLF<br />
szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray())<br />
NetStrm.Write(szData, 0, szData.Length)<br />
' Status.Items.Add(RdStrm.ReadLine())<br />
Dim st As String = RdStrm.ReadLine<br />
Cursor.Current = cr<br />
<br />
'''''''''''''Retriving mails'''''''''''<br />
'Recievemail()<br />
<br />
Dim szTemp As String<br />
'Dim str1 As String = String.Empty<br />
<br />
Dim i As String = "54"<br />
Dim abc As New TextBox<br />
'Dim cr As Cursor = Windows.Forms.Cursor.Current<br />
cr = Windows.Forms.Cursor.Current<br />
Windows.Forms.Cursor.Current = Cursors.WaitCursor<br />
Try<br />
Data = "RETR " + i + CRLF<br />
szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray())<br />
NetStrm.Write(szData, 0, szData.Length)<br />
<br />
szTemp = RdStrm.ReadLine()<br />
<br />
If (szTemp(0) <> "-") Then<br />
While szTemp <> "."<br />
str += szTemp + CRLF<br />
'abc.Text += szTemp + CRLF<br />
szTemp = RdStrm.ReadLine()<br />
<br />
End While<br />
Else<br />
'Status.Items.Add(szTemp)<br />
Cursor.Current = cr<br />
<br />
End If<br />
Catch err As Exception<br />
'Status.Items.Add("Error: " + err.ToString())<br />
Console.Write(err.Message)<br />
End Try<br />
<br />
'''''code end here''''<br />
Catch err As InvalidOperationException<br />
Console.Write(err.Message)<br />
End Try<br />
Return str<br />
<br />
End Function<br />
I am passing this four values to function on page load( i.e. my email servername and password.)Now currently i am retrieving email no 53( i put email no as hard coded because i dont know how to retrieve unread mail.)
Thanks.

Hi Rahul,
I have made an example by modifing the code you posted to log message numbers to a text file. I took out some of your code so you will need to re-intergate it. This code is not perfect (i.e. you will need to add some additional error handling and a few other bits). The server I tested this with is a CPOP UNIX server, so you may need to adapt it to read the server responses differently for other POP3 servers.
UPDATE: If you need it I have a working VB project.
Let me know how you get on.
Regards

Don't repost the same question multiple times in the same day. You didn't give anyone any kind of chance to answer your question the first time, then you reposted it 4 hours later. It's considered rude to spam the forums.
