Re: C# How to install windows services using C# [modified] PIEBALDconsult30-Jul-10 5:53 PIEBALDconsult 30-Jul-10 5:53  Ah, I have only used it on XP and Vista (as administrator)... hang on, I think I have a Win7 virtual machine around here... Hmmm... OK, I got the same thing. Ferb, I know what we're going to do today. Edit: In looking at the messages I see: System.NullReferenceException: Object reference not set to an instance of an object. modified on Friday, July 30, 2010 12:03 PM Re: C# How to install windows services using C# PIEBALDconsult31-Jul-10 5:02 PIEBALDconsult 31-Jul-10 5:02  Oh, yeah, I think I may have had that on Vista too. Because I use a DOSbox to control my Services from the command-line, I simply run it as Administrator. I was able to install and start my Service on my Windows 7 virtual machine, but I wasn't able to access the SQL Server instance on this system.

My system currently has three versions: C:\windows\microsoft.net\Framework\v1.1.4322\InstallUtil.exe C:\windows\microsoft.net\Framework\v2.0.50727\InstallUtil.exe C:\windows\microsoft.net\Framework\v4.0.30319\InstallUtil.exe Other systems may have fewer, and there will likely be new versions in the future -- his install would need to detect which is available and will work. I may have written an application with .net 2 that expects the .net 2 version -- but today someone may want to install it on a system with .net 4 only. The .net 4 version will work, but the install won't know it's there and so will fail. Of course, this is what the PATH environment variable is supposed to be used for, but I think I'm the only one who still uses it. C# interfacing with hardware wjbjnr24-Jul-10 4:03 wjbjnr 24-Jul-10 4:03  Hey guys!!! i wanted to know that is it possible to do interfacing with a biometric device like fingerprint recognition device with c#... I am planning of making a security system in which i will make a database (using sql) which will store and use data from the database using the input from fingerprint device and display from a gui using C# !!.. plz give me a head start!! i really need help. Re: C# interfacing with hardware Dave Kreskowiak24-Jul-10 4:16 Dave Kreskowiak 24-Jul-10 4:16  Sure, it's possible. You just need the SDK for the fingerprint scanner, oh, and a database to hold all the fingerprint data. You'll need to contect the manufacturer of the scanner to get the SDK and that is more than likely going to cost a few thousand dollars.

Re: C# interfacing with hardware Dave Kreskowiak24-Jul-10 6:30 Dave Kreskowiak 24-Jul-10 6:30  Never used it, but you have to buy a minimum of 5 licenses at $35 and change a piece for a total of $176. You also have to buy enough license to cover the number of machines you application is going to run on AND be developed on. So, if you're going to run this on 200 machines, you'll need the 150 pack ($3,920) + 50 singles ($1,765) + whatever dev machines you'll be using. $,$$$...

Re: C# interfacing with hardware wjbjnr24-Jul-10 9:06 wjbjnr 24-Jul-10 9:06  i plan on using only on a single machine.. and then communnicate the database for access of data through a server using asp.net (YES I AM DOING IT FOR FINAL PROJECT) Re: C# interfacing with hardware Dave Kreskowiak24-Jul-10 10:15 Dave Kreskowiak 24-Jul-10 10:15  Yeah, well, you still have to buy a minimum of 5 licenses. Even though you'll only be using 1. And ASP.NET has nothing to do with database access. Were you thinking about ADO.NET?? ASP.NET just puts up web pages.

If there are discounts to be had for existing customers and therefore they want you to log in so they can give accurate prices the should say clearly that the visible prices may not apply to xxx, not hide the price from everyone.

Regards Re: C# . net to perl converter?? ?? Dave Kreskowiak24-Jul-10 4:14 Dave Kreskowiak 24-Jul-10 4:14  There is no such tool, other than you. You have to manually convert the code by rewriting it by hand. I can't find any such converter.

How to covert all formats to pdf using itextsharp? [modified] sush824-Jul-10 1:59 sush8 24-Jul-10 1:59  How can i convert all formats to pdf using iTextsharp? modified on Saturday, July 24, 2010 9:45 AM Re: How to covert all formats to pdf using itextsharp? Pete O'Hanlon24-Jul-10 2:39 Pete O'Hanlon 24-Jul-10 2:39  All formats of what? You can't - as you were told yesterday - how would you convert an exe for instance? Try to make your question more specific. "WPF has many lovers. It's a veritable porn star!" - Josh Smith As Braveheart once said, "You can take our freedom but you'll never take our Hobnobs!" - Martin Hughes.

What if anyone makes a new format? That problem can not be solved, and new formats are being made probably every day, maybe even more often. Re: How to covert all formats to pdf using itextsharp? sush824-Jul-10 3:39 sush8 24-Jul-10 3:39  I mean word document to pdf and text to pdf without using any converter. Re: How to covert all formats to pdf using itextsharp? harold aptroot24-Jul-10 3:42 harold aptroot 24-Jul-10 3:42  If you're not using a converter, how will anything get converted? Re: How to covert all formats to pdf using itextsharp? sush824-Jul-10 3:47 sush8 24-Jul-10 3:47  We have third party tools right.I think by using those we can.But i donno how to..iTextsharp is a third party tool for converting to pdf format. Re: How to covert all formats to pdf using itextsharp? harold aptroot24-Jul-10 3:58 harold aptroot 24-Jul-10 3:58  Ok, but AFAIK it's not a converter. Anyway, what is your question? Re: How to covert all formats to pdf using itextsharp? sush824-Jul-10 4:08 sush8 24-Jul-10 4:08  My task is to upload E-Books.I mean if client uploads any format of book to my server it should be converted to pdf internally.That means I have to convert different formats to pdf internally using .net code.Its not so easy so, i want to use third party tools.But I dont have any idea. Re: How to covert all formats to pdf using itextsharp? harold aptroot24-Jul-10 4:21 harold aptroot 24-Jul-10 4:21  What if you print them to a PDF printer? Most book formats should be printable.. That's just an idea though, I have no idea what would be the best solution. Re: How to covert all formats to pdf using itextsharp? Eddy Vluggen24-Jul-10 5:42 Eddy Vluggen 24-Jul-10 5:42  There's an article on iTextSharp[^]. You said that you're currently converting to PDF with the Google webservice, you'd just need to replace that part. I are Troll
