That's the extension of the file.
Anyway what you're looking for is provided directly by one of the FW classes specifically this method:
System.Io.Path.GetExtension
For full details have a look at this reference in the Help.

Hello to all of you. Many of you reading this message helped me a lot of times. So you all know I'm pretty much a beginner in C++. However, I try to do my best to help everybody with what I know. Some time a go I promised I'll make an article about linking C++ with VB, inter process communication kind of thing, even though this time it's about a DLL and an Application, it still applies to the category.
So, without further delay, I invite you all to take a look at my article, I hope you'll find one or two interesting things there. Thank you all again for being here helping people like myself.
http://www.thecodeproject.com/threads/InterProcessCommunication.asp[^]
In less than 2 months I'll also release the first public beta for the freeware application I've been working on. Many of you helped me at it and you'll all find yourselves at the "Thanks to" section, as I am not one that forgets those who helped.
A nice day (or a good night) to y'all.

Coding.
Dim p As Process = New Process
p.StartInfo.FileName = filePath.ToString()
p.StartInfo.CreateNoWindow = False
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal
p.StartInfo.Verb = "Print"
p.Start()
p.Dispose()

The method you are using here will start the application which is associated with the filetype in FileName.
What you should be doing is create an instance of the application's automation object (which won't show the UI) and then use that object's methods to manipulate the file as appropriate.
Something like this... but beware this code is not complete - you'll need to do some further research for the exact sequence etc. but you get the idea...
Dim ExcelApp As Microsoft.Office.Interop.Excel.Application
ExcelApp = New Microsoft.Office.Interop.Excel.Application
ExcelApp.Visible = False
ExcelApp.Workbooks.Open(filePath.ToString())
ExcelApp.Worksheets.PrintOut(...)
Don't forget to include a reference to the Microsoft Excel 11.0 Object Library (from Project -> References -> COM tab etc...).

ok ill try it but what should i do for .doc and pdf format acutally it doesnot open the application for .ppt format but it does for three(.doc,.xls,.pdf). do you have any general idea?.

Use the correct automation object for each type of file: e.g. .doc and .pdf (?) = Word.Application; .ppt = PowerPoint.Application.
The basic idea is given in my earlier response. You'll need to read up on the methods of each object (should be fairly similar) to find out how to achieve your requirements.

Dim Wordapp As Microsoft.Office.Interop.Word.Application
Wordapp = New Microsoft.Office.Interop.Word.Application
Wordapp.Visible = False
Wordapp.Documents.Open(filePath.ToString())
Wordapp.PrintOut(, , , , , , , 2, , , , , filePath.ToString())
Wordapp.Quit()
hi steve.

Hmmm... works for me without showing the UI (I'm using Office 11 objects). Do you mean that it is starting an instance of WINWORD.EXE as shown in the Task Manager? If so that is correct since that EXE is required to perform the printing of the specified document.
However I'd change this line:
Wordapp.PrintOut(, , , , , , , 2, , , , , filePath.ToString()<br />
to this:
Wordapp.PrintOut(, , , , , , , 2)<br />
otherwise you'll be probably printing to a file rather than the printer - and overwrite the input file in the process.
As far as PDF files are concerned, there is no COM object similar to that provided for the Microsoft applications that I know about to do what you want but I did find this via a Google search re: Acrobat commandline options to automate the print process.
[From the DEVFAQ]<br />
AcroRd32.exe filename - Executes the Reader and displays a file..<br />
AcroRd32.exe /p filename - Executes the Reader and prints a file..<br />
AcroRd32.exe /t path printername drivername portname - Initiates Acrobat<br />
Reader,,<br />
prints a file while suppressing the Acrobat print dialog box,then terminates<br />
Reader.<br />
The four parameters of the /t option evaluate to<br />
path,printername,drivername,and<br />
portname (all strings).<br />
printername - The name of your printer..<br />
drivername - Your printer driver 's name.Whatever appears in the Driver Used<br />
box<br />
when you view your printer 's properties.<br />
portname - The printer 's port.portname cannot contain any "/"characters;if<br />
it does,<br />
output is routed to the default port for that printer.<br />
If using Acrobat,substitute Acrobat.exe in place of AcroRd32.exe in the<br />
command lines.<br />

As far as I'm aware you need to open the correct application for the type of file you want to print, and then print via that application. Your code needs to do this.
I did a Google search for "automate printing files different formats" and found this hit in the results: http://www.silentprint.com/[^] which is a ready-built application for what you are attempting to do. This will save you a heap of headaches. However if you must do this code yourself (i.e. for project/assignment or other reasons) then you'll need to have your own code be aware of all the types of documents likely to be printed and handle them accordingly.
Note - I do not have any interest in the company or product referenced above. I simply found it as one of the hits on Google. There are others that you may want to check out.

Does anyone have a decent pizza ordering program out there. I'm trying to build one as we speak, having no luck

Are you trying to start a pizza shop, or is this homework ?

OK, well, the first thing you need to understand is that if I do your homework for you today, you won't have a clue how to do your next assignment, which will assume that you did this one. The second thing you need to understand is that, homework or not, it's pretty rare for anyone who asks 'I need someone to give me this application' to get the answer they want.
What does your assignment say ? What have you already written ? What bits are you stuck on ? If you demonstrate that you've tried to solve the problem and ask specific questions for where you are stuck, then this site is full of people who would love to help you.

There won't be a next assignment..this is a makeup one I'm working on as the class is over. Here's what it entails
Well designed GUI
Use a menu
Use 3 different controls (intrinsic or ActiveX)
Have a print capability
Implement an application that allows employees of a pizzeria to place customer orders.
Customer info must include name, telephone #, and address
Customer can pay using a visa, mastercard, check or cash
If they pay using credit card or check, the user needs to enter the customers check or credit card number
At least three pizza sizes. Small, medium and large. Six toppings must be available. Prices of pizza and toppings shown on form (toppings are .75 each). Sales tax of 6%
All pricing calculated when user clicks "Place an order"
If no pizza size or toppings are selected, a msg box must appear telling user that it needs to be entered.
clicking "New order" button clears all entries on form

So what have you done already ? Where do you need help ? I take it you intend to never program a computer again in your life, and you're looking for a free ride out of this class ?

How to grab a Frame from an MPEG movie (in VB .net), without saving an image file on harddisk. I've been searching alot for an answer and i couldn't find it. i've using mediadet.writebitmapbits, but this doesn't work for me cause i want to analyse a long video file and i don't want to save each and every frame on my harddisk.

If you want to analyse an entire file, perhaps you need to create a filter for DirectShow that does the analysis you're after ?

Hi
First of all, a language compiler is very sensitive to spelling. Lucky for you, VB.NET is not case sensitive, but you still need to spell things correctly.
Secondly, if you're replying to a post below, you should press 'reply', then the person who answered you will get an email, and the boards won't become an unreadable mess. You may have missed it, but these boards support threading, where you can see exactly who has replied to who.
Having read your question below, I'd have to suggest that you obviously are not at a point where you should be trying to do anything remotely this complex. The world is full of people who try to start programming by writing useful applications, most of them never write one thing worth looking at. If you want to learn, start simple, and build from there. If you don't know 'where to put the code', then you should not be using it, or trying to impliment what you're trying at the moment. You should write a few console apps, such as a basic calculator. Then start playing with some WinForms and learn how that sits on top of VB.NET. Then, when you've got enough of an understanding to be able to use the help that people offer you here, you can start working on something more complex, and ask questions as you get stuck.
Of course, you can ask more basic questions as you work through some more basic examples, also. We're here to help, but you need to do some work too
