View 2 RepliesIn VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example:
With foo
.bar()
.reset(true)
myVar = .getName()
End With
Is there any such syntax within Java?
I have a routine that has an if else statement at the else part it calls another routine. Within that routine it has a msgbox script. At the part that is actually is suppose to show the msgbox it goes back to the previous subroutine at the else statement and runs again but this time it displays. I have never seen this before.

I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

View 3 RepliesHeres my issue which has been bugging me all day and i haven't been able to resolve.
I have a DGV on a form (frmResults) this is linked to a bindingsource of type InventoryItem (popInventory is a list(of InventoryItem) and popular is a list of another class object (StockItem). here's some code to explain better
first the declarations in my globals module
Public Module globals
Friend popInventory As New InventoryItem
Friend popStock As New StockItem
[Code].....
ok what this routine is doing is on the results form is 2 dgv's the first contains stock to keep, the 2nd one contains excess stock to sell. what i get however is all cells on both DGV's are the last item to be read from the popular list. the items are adding correctly (varified with a breakpoint and looking at variables at the time. the popInventory item is added to the relevent List.

View 4 RepliesI'm trying to add a record through access. Below is my code. My problem is that when I add a new record, it adds to the database fine, and goes back to the first record like it should, but when I then scroll through using the BtnNext (button), it replaces the last record with the first record for some reason. This is the UI of it [URL]. A bit of further explanation, I'll have 3 records, IDs 1,2,3 respectively. I go to add another (with its ID as 4). When it's added, the program displays ID 1 as it should. It then goes 2 then 3, but instead of 4 as the next one, it displays 1 again. So 1231.

View 5 RepliesI have created a drawing viewer that displays CNC files. The viewer itself is a user control that i have compiled into a dll. I added a reference to this dll to a windows application and added the control to one of the forms. I also have a reference to other custom dll's within this project. The application works exactly as expected. CNC files can be viewed by using the File>Open menu. You can open a single file or load multiple files into a buffer that will allow you to scan through them using Next and Previous buttons.
What i want to do is open this viewer from another application but have certain CNC files already loaded into the viewer. I know i could get this working but i don't think it would be the best way. Is there a way for me to include a list of files in a shell command? Perhaps the enitre viewer application should be included in a dll that has a LoadFiles() and Show() method.
I am sure this is not a unique problem, but I am drawing a blank (Monday morning) on how to fix it.On my Nav menu, user opens a page with a DDL, selects a record from drop down which opens up a single line in a Gridview with a few fields displayed. User can click Edit and Update two fields or of course Cancel, or select another record from the drop down which displays the new record in the Gridview.All this works fine.Issue is when the user goes to Nav menu and goes to another page then comes back to the first page, the last record that was being viewed is still displayed in the Gridview instead of showing only the DDL and waiting for a selection. Its as if the Page Load event does not fire again (In fact it does not). I need it to fire as an initial load, in order for the 'If Not ISPostback Then' logic to properly fire.
