A quick implementation of an encrypter which can't be cracked by frequency analysis.

A simple implementation of IServiceProvider for use in plugin style architectures.

MySQL 5.x Stored Routines, PHP Session Values, a little CSS oh my! Complex to set up but easy to impliment. Geared toward security, simplicity (of use) and convenience.

This little number will allow the contents of other pages to be included or embedded into the rendered HTML of an aspx page. Using the WebClient class from the .NET framework, you can conditionally load pages, even manipulate the HTML before it is rendered and in this example, fill in forms and execute javascript actions.

The following example shows how to auto-login to an Exchange Server - this was something requested for inclusion into our portal, but I left out the logic that pulls/decrypts the real password - for obvious reasons.

Enjoy!

This snippet allows an aspx page (c#) to accept URL parameters to allow styles or script to be dynamically appended to the rendered page.

I wrote this simple snippet to allow one of our vendors to accept a style override so that their application would morph into something more closely resembling our own portal application. Please see screenshots for clarification.

If anyone has tried using the .NET Graphics API, they know that replacing pixel colors takes a long time to complete. I did some research and found a good source. This code will adjust the color to greyscale by Binary.
The page is http://www.navicosoft.com/software_articles/softwares_articles_index.html for more information. It is under Basic Image Processing in the list of articles.

This code was something I used to monitor the keys that where press while a user would be entering text into a text box in my application. I monitored and watch for the user to hit the "Enter" key and then perform some task. Handy code for chat applications.

This could be used for any type of simple hash checking. It could also be used to store a "password" that had to be verified. This code is completely managed.

Generates an 88 character secure hash string for the passed in strings.

This snippet effectively reads an XML document using XPathDocument (read-only) instead of using the DOM. This snippet returns the full element values in between elements. For example:

root element
code element
This is a test.
/code element
/root element

GetXmlString("/root/code"); //returns 'This is a test.'

Write a set of bytes into a 'so-called' binary file. The point is that we use BinaryWriter here and we have a byte array as input.

This snippet generates a secure hash string using VB.NET

A function to determine if the input filename is valid on Win32 platforms (that is, it does not include invalid characters, such as :\?...)

Write a set of bytes into a so-called binary file. The point is that we use BinaryWriter here and we have a byte array as input.

Set the read-only attribute of a file to true or false.

This litle snippet shows how to store passwords and then check inputed passwords if they are correct.

(In this snippet we use som pseduo code for the database connection).

This is a function that receives a dataTable and return it in a pivoted way.

Simple loop through datatable

Second example of reading an excel file. Reading with a SELECT syntax.

First Example of reading an excel file. Just reading the file and loop throught 10 rows.

I will send the second example soon !!!

Example that shows how to populate a winforms combobox with csharp. It uses Data Access blocks (SqlHelper).

Prior to NETCF 2.0, this was a royal pain. Now, it's pretty straight-forward.

These three related functions provide basic Clipboard operations for text. While not terribly useful by themselves, they become more useful when attached to a field's context menu or, better yet, implemented in a custom control.

This snip opens any kind of document (e.g. .PDF, .DOC, .C, .HTM, etc.) using the default application associated with it. This relies on starting a new process with the .UseShellExecute property set to true.

The main overloaded function OpenDoc(filename) will open any associated document using the default OPEN verb. If you are trying to edit a file, for example, a command file, then you need should call OpenDoc with the "EDIT" verb. Some associations also a "PRINT" verb.

Since the return result is a System.Diagnostics.Process object, you can also monitor or kill the process.

Example:
OpenDoc("C:\\SomeDocumentation.pdf");
OpenDoc("C:\\AWebPage.htm", "EDIT");
OpenDoc("C:\\Test.txt", "PRINT");
System.Diagnostics.Process doc = OpenDoc("C:\\WebPage.htm");
