Convert Date From US Format To UK Format?
Dec 15, 2009All of my regional settings in control panel are set to UK but when I retrieve a date from an SQL database (run from my PC) in my program, it appears in the MM-DD-YYYY format rather than the DD-MM-YYYY format that I expect.
After a bit of troubleshooting I found that this is because of the fact that SQL server always stores its dates in that format - so then when my program reads the data from the database it interprets it as being the US format.How can I convert this to UK format bearing in mind I am working with Date objects not strings?

Windows Form Print Black & White?
Aug 20, 2010I been playing around with some code I found on internet and I am probably almost where I need to be. Using the printdocument I am able to get the active form in my project to print.

Problem: IF a text box fields background color is too dark then the entire box shows up in black. If a text box field data is Selected it also is too dark and comes out white.her is code I found for turnign to B&W
