Displaying an Image Without Locking its File(codehill.com)

submitted by amgadhs(85) 1 year, 10 months ago

The PictureBox control is one of the most used controls in Windows Forms applications. And sometimes you might want to delete the image file that is displayed on it. Doing so with an image displayed using the Image.FromFile function will result in a file locked exception. And file will stay locked until the program exits, even if you set the variable to null. read more...

Saving User and Application Settings in WinForms(codehill.com)

submitted by amgadhs(85) 2 years, 11 months ago

This way is cleaner because when an application is uninstalled or deleted the end user does not have to worry about left over registry keys or INI files in the Windows directory. read more...

IMDb does not provide a way for developers to use their data, so I wrote the code below to screen scrape or web scrape the details from the movie’s page. It gets the title, director, genre, release year and tag line of the movie as well as the thumbnail. read more...

Using the Phidgets LCD With Outlook(codehill.com)

submitted by amgadhs(85) 3 years, 1 month ago

When I got my Phidgets StarterKit I decided to use the LCD that came with it with the Outlook Addin I developed for my previous post Capturing Outlook 2007’s New Mail and Reminder Events. The LCD connects to the PC through USB. It has no memory, so the control program runs on the PC. The libraries needed to develop programs for the hardware can be downloaded from their website along with some sample code too. read more...
