Hi,
Want help to know how to read pdf file content using visual basic 6.

Wow - why are you using VB6 ? VB6 was only ever useful because of the C++ components it could use to do real work. You need to find someone who still sells VB6 components, and buy one to read PDFs.

I have a bigest project in my life. I develop it using VB.NET.
My project can saperate into many part here:
- client-user account
- customer account
- material account
- store
- point-of-sell (storefront)
- purchasing cycle
- and accounting
In the store and point-of-sell parts I need to use barcode reader and I need to generate barcode label by myself but I can't find any resource about barcode format and generating
If anyone can help me through this problem or can point me to any resource, I would thank you very much.

You can call C# dlls from VB.NET.

If you didn't find anything, it's because you either didn't search at all, or your eyes were closed when the search results came up.
Google for generate barcode in vb.net[^]

Hey, I ask you for a help not for a complain but thank you for your response.
First of all I'm newly in microsoft technologies and I never learn for the barcode technology before and I need to implement it for my project but I spent my time for about 6 hours to find topics about barcode on the internet, I searched on google but when result came up it's only commercial product advertising, I tried not I didn't find. I accept that I'm not smart but at least I'm try to get it successed so I ask you to help me.

The problem has nothing to do with either. If you want to successfully write code, no matter the language or technology, the single most important skill you must have nothing to do with programming. It's the ability to do research. How to find information using, and refining the correct search terms, how to hypothesize, and how to test those hypothesis. If you don't know this skill - learn it. It's far more useful than knowing how to write code.

All you need is font, and calculate check digit when forming the bar code (ie Code+CheckDigit).
And I _assume_ that, as you might be printing bar code labels to be pasted on products, and the labels might not be large enough to be scanned, if you use a normal printer, you should get a bar code printer instead. The ways of configuring the bar code printer should come with the bar code printer.
To use the barcode reader, you don't usually need to do much else, as the reader acts as a keyboard. Just make the cursor is on the capturing control (textbox) and the barcode is of correct code.

Thank you very much, I got the concept. Now, I'm getting barcode fonts and paper about how to generate checking digit (I got it from one article about barcode in this website and he posted the URL to find out how to generate barcode checking digit) and I will implement it.
Thank you.

CodeProject holds over 30 articles on barcodes, some use special fonts, some draw
the lines themselves.
in 6 hours you could have read all of them.

I have a dll file can be linked with VB 6.0. In VB 2005, I tried to use "Add Reference" to link the dll, but I got an error for checking if the file is assembly or COM components. Can I do "Declare" like VB 6.0 to call functions in dll?
VB 6.0->
Public Declare Function Cmod2WireWriteBlock _
Lib "cmodcomm.dll" _
(ByVal DeviceAddr8 As Integer, _
ByRef InBuffer() As Char, _
ByVal BUFSIZEcount As Integer) _
As Boolean

Add reference is only good for COM or .NET dlls. p/invoke may work.

Heya,
Just a quick question. I am writing a stack application in which there is one requirement that data structure must make use of a block of memory allocated when the stack is constructed. Now which data stucture is most appropriate for this. Is it sensible to use linked list or not.

I think you should put on your flame-retardant suit.

A Linked list, by its very nature, is dynamic; you can't use a stack for it.
Unless I'm making a huge mistake (and I've made plenty in the past  ), you are going to be stuck with arrays*.
* You _could_ also use fixed-size stacks and queues and dequeues, but they're just sexed up arrays. 
Cheers,
Vikram.

A linked list by it's very nature is in fact a stack without push and pop functions.

Your best bet would be to ask this over at the Mathematics and Algorithms[^] forum.
(if it were me, I'd just allocate an array and keep an index to the top of the stack. since you're dealing with a fixed size predetermined from the start, that's how I'd do it.)

Just grab the return value of Process.Start, then wait for that process to end.

Many thanks for your reply. Let me be more specific to my problem.
- I am calling an 'Outlook 2000 New Message window' from VB.Net from.
- On Email ItemSend event I am updating the database by using a VBA macro
and closing Message window.
- When I get focus back to my VB.Net application, I want to refresh my current form with recently updated data.
I am using the following code to create a new mail.
Public Sub NewEmail(ByVal txtEmail As String, ByVal intContId As Long)
Dim objOutlook As Outlook.Application
Dim objNamespace As Outlook.NameSpace
Dim objMAPIFolder As Outlook.MAPIFolder
Dim objItem As Outlook.MailItem
Dim objProp As Outlook.UserProperty
objOutlook = New Outlook.Application()
objNamespace = objOutlook.GetNamespace(Type:="MAPI")
Try
'creating a process but it's not working
Dim Proc As New Process
Dim ProcInfo As New ProcessStartInfo
ProcInfo.CreateNoWindow = True
ProcInfo.FileName = ""
ProcInfo.UseShellExecute = False
Proc.StartInfo = ProcInfo
Proc.EnableRaisingEvents = True
AddHandler Proc.Exited, AddressOf ProcessExited
Proc.Start()
objMAPIFolder = objNamespace.GetDefaultFolder & _
(Outlook.OlDefaultFolders.olFolderInbox)
objItem = objOutlook.CreateItem(Outlook.OlItemType.olMailItem)
objItem.To = txtEmail
objProp = objItem.UserProperties.Add("ContactId", & _
Outlook.OlUserPropertyType.olNumber, False, False)
objProp.Value = intContId
objItem.Display()
objOutlook = Nothing
objNamespace = Nothing
objMAPIFolder = Nothing
objItem = Nothing
objProp = Nothing
Catch ex As Exception
msgbox err.message
End Try
End Sub
I would appreciate if you kindly guide me how to include a process object in this function. If you think there is a better way to solve this problem, kindly let me know.
Thanks again

You already have one; apply Christian's advice on that process.
