-- modified at 4:54 Thursday 9th August, 2007
if you mean usercontrol provide me with an email and I'll mail you a example project I just created for someone else
I can't post it here and the code to long
You can mail me from this site (use email instead of reply)

I've come across some sample code and at the top of the code, after the imports and before the class declaration, it says module BLAH. What is a module. I've never seen this before.
Thanks

MSDN says:
A Module statement defines a reference type available throughout its namespace. A module (sometimes called a standard module) is similar to a class but with some important distinctions. Every module has exactly one instance and does not need to be created or assigned to a variable. Modules do not support inheritance or implement interfaces. Notice that a module is not a type in the sense that a class or structure is — you cannot declare a programming element to have the data type of a module.
You can use Module only at namespace level. This means the declaration context for a module must be a source file or namespace, and cannot be a class, structure, module, interface, procedure, or block. You cannot nest a module within another module, or within any type. For more information, see Declaration Contexts and Default Access Levels.
A module has the same lifetime as your program. Because its members are all Shared, they also have lifetimes equal to that of the program.
Modules default to Friend (Visual Basic) access. You can adjust their access levels with the access modifiers. For more information, see Access Levels in Visual Basic.
All members of a module are implicitly Shared.

So do I access the subs and functions of a module as if they were in my code? I do not need to declare it or instantiate it?

Hi,
I suggest you try it. And look it up on MSDN. Or read a book on VB.NET
In fact the combination of these is the best way to make real progress.

How can I make a Column on DataGridView accept only Numbers .. like Phone or price field >>>
jooooo
|
|

Hi jooooo
In design mode, select your data grid, select Edit Column from proeprtys, select your column from left panel and from right side options, select DataGridViewCellStyle prperty. Click on .. btn. In format, select Numeric for phone number with Decimal 0 and for price you can go for Numeric or Currency fomrat also. After setting this, if user enters anything else, Datagrid will throw exception and not allow user to input anything else.
Hope this helps the best
Thanks
Terry

I need some advice on how to handle semi global variable. I have had this issue before but currently its with a tracesource. I currently have a tracesource for each command I am creating in a toolbar. This way I can tell which command is giving me trouble. However I created a module called utilities that contains many subs and functions that I use between all of them. How do I set the values for this tracesource? The commands all have a oncreate sub that I use for the others so they are only class level. I can create the tracesource on the initialization of the toolbar but then its a global variable right? I am going to probably have this problem on several variable or objects so I would like to do this the best way.
Thanks

What is a 'semi global' variable ? I've never heard of such a thing.

Thats a word I made up. The variable is a tracesource for the module. But I am not sure how or when to set its value. If this is the tracesource of the form I set it on the form create event. But my module has no create event. So when I can a sub or function in my module my trace statements will fail because the tracesource has not been defined. I don't really want to make a global variable and set it at the start of the program because I only need it if that module is going to be used. Does this make any more sense?

I need a small help with a piece of code in VB.NET, that I am not getting right. I am trying to compare two directories, that have subdirectories containing files. I will have to compare both the directories and find out which subdirectories are the same (subdirectories having same files) and which subdirectories are different.
The code works fine till it gets into the respective two main directories and fetches the subdirectories present in them and also the files present in each of those subdirectories.
The problem I am facing is that the looping seems to be incorrect, which I am unable to debug. It doesn't compare all the subdirectories I think I am not getting the logic to proceed furthur. It breaks after one subdirectory. I will be very grateful, if anyone of you can assit me with the logic.
The code I have written is as below.
Dim file1byte As Integer
Dim file2byte As Integer
Dim fs1 As FileStream
Dim fs2 As FileStream
Dim path1 As String = mats.GetSetting("UnpackLocation") 'Directory 1 location
Dim getdir1 As String() = Directory.GetDirectories(path1)
Dim diren1 As System.Collections.IEnumerator
diren1 = getdir1.GetEnumerator
diren1.MoveNext() 'Points to the first subdirectory of Directory 1
Dim path2 As String = mats.GetSetting("path2") 'Directory 2 location
Dim getdir2 As String() = Directory.GetDirectories(path2)
Dim diren2 As System.Collections.IEnumerator
diren2 = getdir2.GetEnumerator
diren2.MoveNext() 'Points to the first subdirectory of Directory 2
Dim dirUpack1 As String() = Directory.GetFiles(diren1.Current) 'Gets the Files from the first subdirectory of Directory 1
Dim en1 As System.Collections.IEnumerator
en1 = dirUpack1.GetEnumerator
en1.MoveNext() 'Points to the first file in the subdirectory
Dim dirUpack2 As String() = Directory.GetFiles(diren2.Current) 'Gets the Files from the first subdirectory of Directory 2
Dim en2 As System.Collections.IEnumerator
en2 = dirUpack2.GetEnumerator
en2.MoveNext() 'Points to the first file in the subdirectory
Do
diren2.Reset()
diren2.MoveNext()
Do
en1.Reset()
en1.MoveNext()
Do
en2.Reset()
en2.MoveNext()
Do
' Determine if the same file was referenced two times.
If (en1.Current.ToString() = en2.Current.ToString()) Then
mats.ResultsLog.WriteError("Same File has been referenced Again!")
Exit Sub
End If
' Open the two files.
Console.WriteLine(en1.Current.ToString())
Console.WriteLine(en2.Current.ToString())
fs1 = New FileStream(en1.Current.ToString(), FileMode.Open)
fs2 = New FileStream(en2.Current.ToString(), FileMode.Open)
' Check the file sizes. If they are not the same, the files
' are not equal.
If (fs1.Length = fs2.Length) Then
Do
' Read one byte from each file.
file1byte = fs1.ReadByte()
file2byte = fs2.ReadByte()
Loop While ((file1byte = file2byte) And (file1byte <> -1))
' Close the files.
fs1.Close()
fs2.Close()
If ((file1byte - file2byte) = 0) Then
Console.WriteLine("The files are Same.")
GoTo jump1
Else
Console.WriteLine("The files are not Same.")
End If
Else
fs1.Close()
fs2.Close()
Console.WriteLine("The files are not Same.")
End If
' Return the success of the comparison. "file1byte" is
' equal to "file2byte" at this point only if the files are
' the same.
Loop While en2.MoveNext() = True
jump1: Loop While en1.MoveNext() = True
Loop While diren2.MoveNext() = True
Loop While diren1.MoveNext() = True
We will have to see if all the files in both the subdirectories are same, and if they are the same then Print that the SUB-DIRECTORIES are also same.

can someone please look at the problem?

hey,
gave it a quick scan looks ok ish.
have you not considered doing something like (excuse Pseudo)
function checkDir(D1,D2) as boolean
for each File in D1
compare it with D2.File
if any not equal then return false
next
'now check subdirectories
for each Sub in D1
if checkDir(D1.Sub , D2.Sub) = false then ' Its not equal - pass it up
return false
End if
next
End function
start the function with an Answer = checkDir(StartDir1,StartDir2)
its recursion which you may or may not like but it seems simpler somehow.

Hello Martin.
Thank you so much for your help. I could build the code from the logic you have provided and that worked. So, I appreciate your concern.
Ravi.

on keypress ( isuggest putting the form's keyprievew on and using the form keypress):
If e.KeyChar = CChar(13) Then<br />
e.Handled = True<br />
Else<br />
MyBase.OnKeyPress(e)<br />
End If
If this disables enter also then just put your normal enter actions after e.handled = true.

it's good
thanks my fried . but there's a small edit on the last code
If e.KeyChar = CChar(ChrW(13)) Then<br />
e.Handled = True<br />
Else<br />
MyBase.OnKeyPress(e)<br />
End If<br />

Hello all,
Heard some great stuff about the code project so I decided to join the community and hope to be able to help others in the future as well.
Not yet there though since i'm fairly new to vb.net
Anyway: I need to print PDF files that are on disk to a network printer.
I searched for some printing code on the net and found several similar approaches.
However printing only seems to work to local printers, not network printers.
Even on local printers it sometimes fails.
I used the following code:
Dim PD As New System.Drawing.Printing.PrintDocument
Dim DefPrint As String = PD.DefaultPageSettings.PrinterSettings.PrinterName PD.DefaultPageSettings.PrinterSettings.PrinterName = .PrinterNaam
Dim NP As New Process()
NP.StartInfo.FileName = "c:\test.pdf"
NP.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
NP.StartInfo.Verb = "Print"
NP.Start()
NP.WaitForExit(9000)
If Not NP.HasExited Then
NP.Kill()
End If
PD.DefaultPageSettings.PrinterSettings.PrinterName = DefPrint
any way to improve this piece of code ?
it launches the print command to acrobat, but maybe there is a better trick to do the printing.
How comes this doesn't work for network printers ?
Thanks in advance,
Nick
