Does Anyone know How to read multi-line strings? I am using XmlWriter to write a Multi-Line Textbox to an Xml Document. The Trouble Is I can't figure out how to get the reader to read that multi-line element. I know the writer is writing it in multi-line, but the read just squashes the lines together. Does anyone know how to read that multi-line element properly?

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
2008 Array Processing and Sequential File Processing
View 14 RepliesIm a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008
