View 1 RepliesGenerating A Data Table From INSIDE?
Feb 6, 2009Does anyone know a way for a datatable to be generated INSIDE the code of VB? It would be a "backup" datatable generation subroutine to be run in case the original datatable got damaged somehow (bad hard drive sectors, virus, whatever). It would need to be able to generate a "blank" datatable that could be filled in while running the program, instead of having to do it from an outside source (like Access).An example would be an "inventory" datatable (X product, Store Code, Manufacturer Code, Cost, Price).

View 5 RepliesRowSpan On A Table Created Dynamically Located Inside Another Table?
Apr 24, 2009I'm writing a scheduling program that queries a MySQL database for today's appointments and uses a Table Layout Panel with employees on the top and times on the left to display the schedule. I am trying to add another table ontop of that table for each appointment and set the rowspan of that dynamic table to occupy the time slot of that appointment from start to finish.ll the appointments appear in the dynamic table and each dynamic table appears in the appropriate starting positions in the main table. When you are designing GUI's and put a Table within a table, you get a RowSpan and ColumnSpan option for that inner table. The problem I'm having is the dynamic tables are not giving me a RowSpan option, which I believe is because it was created using code and doesn't know that it's inside another table.Here is part of the code... This code is inside loops for each appointment of each employee

Open And See Data Inside A .ISO Bin File From Inside An Application
Mar 30, 2010im new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.
