View 3 RepliesI was wondering if there is any advantage to do everything programmatically instead of using design view to create forms, controls etc. Would there be any difference in size and/or performance after you compile it? So far I've been doing pretty much everything programmatically, specifying all the properties that aren't default for my forms controls but I am starting to wonder is there are any advantages to this, apart from making it easier (sometime) to manage and change the behavior of my controls.

I've read many posts about disabling Alt+Ctrl+Del and Ctrl+Tab, etc. I'm not looking to do that. What I'm trying to do is create an app which will be hidden, and then need to be unhidden from "anywhere." For example, if I have an Excel spreadsheet open, I want to be able to use a combo like Ctrl+U to Unhide my program, but I do NOT want it to underline the text in the cell I'm currently in (which Excel will normally do). I don't want to worry about disabling or changing shortcut combinations for Excel, Word, etc.

I am currently iterating through a loop and redimensionalising my array every time I need to add a value (as you can imagine this takes some time for a redim every loop) is there a way I can implement a push similar to ruby or java?

View 1 RepliesIn my inventory mobile application , i use RDA.using the mobile device ,i update only the Barcode of a particular Item which is in the Item Master(.sdf file). then I push the tables to the SQL Server.there is a web application handles all the other functionality , including Item Master Changes.for and eg.
(1) I pull the Item master to the Mobile Device.
(2)change the Item Name from the Web application.(NOT FROM DEVICE)
(3)Update Bar code from the Device
(4)push table from mobile Device to SQL Server.
In this situation Old Item Name is replaced.My need is only to update the Barcode.
I have a fairly simple form that uses a SQLAdapter, a DataSet, and a BindingSource to allow users to navigate through the records in a table. Each time the user navigates to a new record, I update a DataGridView control that shows the appropriate records in another table. Now I'm trying to add a new record to the main form, using this code:
bs.AddNew() 'bs is the BindingSource object.
bs.EndEdit()
daCCS.Update(dsCCS,
"tblCostCodeStructures") 'da and ds are the DataAdapter and DataSet, respectively.
dsCCS.AcceptChanges()
Now, this seems to work alright, but it doesn't seem to actually retrieve a primary key for the new record from SQL Server. This is important, because without a primary key there's no way to requery the DataGridView and tell it what the correct Foreign Key is for whatever new records a user may create. I know the code is writing the record, because I can open SQL Server and see the new record, and I can close the form and re-open it to see and edit the new record just fine.
However, I need a way for the new record to be immediately available. Obviously, closing and re-opening a form every time the user adds a new record is not going to work! How can I make it so that as soon as the user creates a new record, that record is submitted to SQL Server, the dataset updated, and the form updated so that I have the new Primary Key field available?

I'm trying to create a stack of menus so I can navigate forward and back between different menus, however when I get down the push line to push my menu onto the stack I get the following error:"NullReferenceException was unhandled: Object reference not set to an instance of an object.". I'm unsure what the problem is as I am trying to push an object onto my stack, a menu object. The same error occurs even if I change the object I am trying to push directly to apple as well.
