The ideal of warriorship is Say, as an example, that your boss hands you a file with a list of names, emails, and phone numbers, and wants you to read the file and do something with the information, like put it into a database or just print it out in a nicely formatted report.

The file's columns are separated with the TAB character and would look something like this:. Here's the full listing we'll be working with:. Note: This pulls some code from the tutorial on how to read and write files in Perl. What it does first is open a file called data. After reading in a line, any whitespace is chomped off the end of it. Then, the split function is used to break the line on the tab character.

To the left of the split's sign, you'll see that I'm assigning a group of three different variables. These represent one for each column of the line. Finally, each variable that has been split from the file's line is printed separately so that you can see how to access each column's data individually. The output of the script should look something like this:.

DataRowView" as it's contents. The drop down area shows all the names and the rest of the text boxes update as expected, but the upper contents of ComboBox1 never visually change. I have 2 scenarios at this point. When I change the contents of ComboBox1 manually I want to test the data table to see if there is an entry that matches and update the text boxes accordingly. If I manually change the contents of one of the text boxes, I want the new data updated in the table and written back to the CustDB.

TnTinMn Feb pm. I was bored so I thought I would give it a try. I'm still new to WPF. Besides, I found many comments that doing a filtered ComboBox was pain and I like a challenge. I now agree with a comment that I found that WPF can hurt your brain, : WinForms is so much easier to to achieve this with.
