Here is the C# sample code which will help you
using System;
using System.IO;
// Read your text file with names
// Form path1 with studentname
// Form path2 with studentid
// Execute the following code in a loop
string path = "C:\xxx\xxx\" + "Studentname.txt";
string path2 = C:"\xx\xxx\" + "StudentID.txt"
if (!File.Exists(path))
{
// This statement ensures that the file is created,
// but the handle is not kept.
using (FileStream fs = File.Create(path)) {}
}
// Move the file.
File.Move(path, path2);
Console.WriteLine("{0} was moved to {1}.", path, path2);

Hello,
Can someone write an article about good database practices for ASP.NET applications. CP has more than a million users, if they are willing to share their secrets of optimized database code.
Thanks,
Pankaj

i need some materials on how we will ensure database concurency using dataset. according to me it is not possible through datareader.
any how if you have any idea about this situation please share that with me.
one more thing how we will implient custom paging in dotnet(asp.net).

I'd love to see an article that demonstrates the most basic necessary objects to place an ap into an installer. I'm referring to the most standard Windows Installer kinds of elements:
- Check to see if user has at least the .Net Framework and the version is compatible
- Prompt user for install location and create new folder if none exists
- Ask user if they want a shortcut icon on the desktop/quicklaunch
- Ask the user if they want to view the readme
- Include an uninstaller
Thanks

Hmm............. Given your handle is 'tanstaafl', would you be willing to pay for such informaiton 
What languge would you want to see examples in?
Or are you looking for a document describing WHAT do do versus a concrete example of how to do it?
Are you concerned about setup file size (file compression is required)?
Do you know if you need Windows Logo compliance (must use MSI if yes)?

I certainly would offer whatever time and skills I have to offer in exchange for the knowledge of how to create a installer that will work correctly with a PC that has just the .NET Framework.
I wrote a program in Visual Basic .NET and had a difficult time getting it to work on two other computers, one had just the framework, and the other had a full version of Visual Studio.NET.
I finally dumped every file and folder pertaining to the program onto the pc with just the framework and it worked.

It's sooooo much easier if you download the Visual Studio .NET 2003 bootstrapper plugin. Now you need not write your Win32 bootstapper code to check for framework version, MDAC components, or any of your other concerns. Just install the plug-in, create a new setup(deployment) project in the IDE, and point and click your way to an elegant installer! Rock-on.

Is there a FREE software project out there that can serve as the front end for a CD-ROM.
I want the option to launch a few programs, HTML files, text files, etc. as the CD-ROM is inserted.
I searched here using 'CD-ROM' and 'AutoRun' and did not see or else overlooked something. Tried the same search on SourceForge. Am I using the wrong keywords?
Should I write one myself and post it here?
Thanks.
|
|
|
|
|
yeah, your searching for the wrong word. If i understand you correctly. From what I understand, you want to search for "autorun.ini"

Thanks for the keyword search suggestion.
I found some on www.installsite.org, some with source, some without.
They did not really do what we needed for our current project, so I already wrote one in MFC.
|
|
|
|
|
your wrote what in MFC? I'm confused...
/\ |_ E X E GG
|
|

|

I just made my own CD-ROM/application launcher instead of using one already out there.
The AutoRun.Inf starts my program written using MFC. I have options to view release notes, browse CD-ROM, view license agreement, launch setup programs.
That is all I was looking for initially, but the ones I found were too limited, cost too much, or had strange runtime overheads.

|
|
|
|
ooops, sorry about that. I meant .inf...
Ok, I understand now, good job.

Would anyone be interested in an article demonstrating a component that does High-Low identifiers as an alternative to Identity columns in SQL?
For those not familiar, the idea is that you assign a unique id to a row of data before it is ever saved (in code). This has several benefits, like (off the top of my head, I'm sure there are more):
* Row Ids are unique, even across tables
* Replication is greatly simplified
* Inserts are fast (because we don't need a select query to get back the @@IDENTITY)
* SELECTs are also fast, since recent SQL databases have native support for Guids.
The High-Low term refers to the specific technique used to do this in a way that guarantees uniqueness.

I have used this method many times in the past. It has only one draw back. GUID's are not inherently sortable on SQL. This can hurt paging schemes (i.e. Give me the first 10 then the next 10) and random picking (i.e. random drug testing).
Solving these issues is more informative then simply choosing a GUID for your primary key.
By the way, joins & indexes are a little slower with GUIDs then with INTs. Nothing measurable until you get into large tables but, they are slower.

Hello
I just want to learn a modern programing language and i dont know what to do !
i know a little of traditional c++ and visual c++.net but i want to
choose one of these : "visual c++.net" or "visual c#.net".
now would u please guide me to choose one of these? and would u please say me which one is better or differences between them?
thank u very

We should not make that choice for you!
C++.NET is often referred to as managed C++. Since you can care less about resourses and memory, your development time is reduced. I don't know the details about managed C++.
C# is a whole different thing. Besides the fact that it is a managed language, it also is 100% object oriented (like Java).
The major advantage is that your development time decreases a lot, but your distributable becomes bigger and slower.
I recommand that you read a few articles about Managed C++ and C# that can be found on msdn[^], and then choose the language that you feel comfortable with.
A student knows little about a lot.
A professor knows a lot about little.
I know everything about nothing.
