Adding to what kubben said, you can use the same handler for all buttons,
then inside that handler use the first argument "sender", cast it to Button
and you can read the button's name, or whatever you want to access.

I'm building a system to create batch files, such as fee statement for every person, and one person per page. Could anyone tell me what the steps are to do this, please?
Also, is it possible to code such as the summarised total amount of fee payment by all people on a single file? I mean creating a method on the crystal report with just a text field of that total amount. Because I can't find a way to do it.
Your Helps are Deeply Appreciated. Thank You Very Much

Hello!
I have a 'picture box' on a windows form. When i click witin picture box a textBox control is added to picturebox at the location where i have clicked.
I want to know, how can i drag that text box within the picturebox at runtime?
I would be thankful for any help....

By writing code to capture mouse actions on the textbox, and to change it's properties so it follows the mouse.
Also, you will probably find it easier if you get rid of the picturebox, draw the image yourself, and just add the textbox to your form. The picturebox is adding complication that you do not need.

Why would you want the '>' to be outside the quotes? Why is your command not:
Shell("cmd /c net view > C:\cnames.txt", AppWinStyle.Hide, True)
I'd guess that it's actually resolving the first part of your parameters, so what you've got is actually:
Shell(False, AppWinStyle.Hide, True)

Hi,
Is it possible to dynamically change the name of the web services ??
If yes, Kindly let me know how to go about it.
Thanx in advance.

What would you need to do this for?
I don't know about changing the name but you don't have to do a 'add web reference'. you can dynamcially choose webservices on the fly as well as point to different locations for test/qa/production/etc...

Hi,
I'm having FileStream.Write behave rather oddly.
The code below should take file a.txt and append it to file b.txt :
Dim buffer As Byte()<br />
Dim bytesRead As Integer<br />
Dim fStreamIN As New FileStream("c:\a.txt", FileMode.Open, FileAccess.Read)<br />
Dim fStreamOUT As New FileStream("c:\b.txt", FileMode.Append, FileAccess.Write)<br />
ReDim buffer(fStreamIN.Length)<br />
<br />
bytesRead = fStreamIN.Read(buffer, 0, fStreamIN.Length)<br />
MsgBox("Read bytes:" + Str(bytesRead) + " Expected:" + Str(fStreamIN.Length))<br />
MsgBox("byte 1:" + Chr(buffer(0)) + vbCrLf + _<br />
"byte 2:" + Chr(buffer(1)) + vbCrLf + _<br />
"byte 3:" + Chr(buffer(2)) + vbCrLf)<br />
fStreamOUT.Write(buffer, 0, buffer.Length)<br />
<br />
fStreamOUT.Flush()<br />
fStreamIN.Close()<br />
fStreamOUT.Close()
I test with :
a.txt "abc"
b.txt "<this is="" the="" orig="">"
Now when I run this code, the characters in a.txt are read correctly to buffer, but the file b.txt contains :
"<this is="" the="" orig="">扡c"
What on earth is going on ???
cheers guys

You need to read it as text, not bytes. The odd character is probably caused by the file containing some sort of encoding identifier at the start, which you then appended blindly on the end of the file.

I want to add a warning:
Your code is unsafe, you somehow expect a number of bytes being read that could
differ from what you ask, but you don't use it when writing the data.
bytesRead = fStreamIN.Read(buffer, 0, fStreamIN.Length)
...
fStreamOUT.Write(buffer, 0, buffer.Length)
it should have been: fStreamOUT.Write(buffer, 0, bytesRead)

I am building a 3 layer solution.
Well, I use the data application block from enterprise library 3.1 and visual studio 2005.
I have configured my app.config with the editor that enterprise library recomends. I have defined my connectionstring and my provider.
When my application run, appear a error, objeto no referenciado.
It is generated from my dataaccess layer.
Someone says to me that app.config must be in the client layer.
I have put my app.config in my dataAccess layer. It can be?
So,if my app.config is in the client layer, Do I need define something else or my application block will recognize it automatic?
Tanks in advanced

At a guess you are coming from an access environment where you can have calculated or virtual columns.
These do not exist in SQL Server. You have 2 options
1 do the calculation in the select query when you retrieve the data
2 create a view of the table with the calculation in the view.
