Your first step is to work out your data model. Think about the data elements you want to store and how they relate to one another.

I think the object of school assignments is that you do them yourself

or possibly [CODE]combobox.refreshitems[/CODE]

You are best to use a mac. Download xcode and start from there. there are some excellent tutorials on iTunesU

Create a dataset using a SQL statement to combine your multiple data and then use this as the recordsource for the datagrid.

No switch takes an integer you need if then else if construct if ([textfield.text isequaltostring:@"someCase"]) { // do something } else if ([textfield.text isequaltostring:@"anotherCase"]) { // do something else } else { // do yet another thing }

That is not a label that is a text field. Drag a label across from the object library, it will have type of UILabel. If you are using the latest version of xcode you should be putting an underscore on the front when referrring to them locally, [_label setText=@"Hello World"]; …

NSArray *dateFormats = [NSArray arrayWithObjects: @"dd/ mm / yyyy", @"mm / dd/ yyyy", nil]; NSString *selectedDateFormat = [dateFormats objectAtIndex:formatSelected];

Yes, you do not need to synthesise them if the setters and getters are as simple as above. In recent versions the "_" on the front is for the internal representation of the property. You also do not need the statements on lines 3 & 4. Properties are the external …

WIA is your best bet if your scanner drivers support it. Otherwise you will need to use TWAIN. There is a product called EZITWAIN which I have used at a client where WIA did not work.

Are you sure this is the correct approach, the barcode scanners I have used present the data as if it had been typed on the keyboard. ie. you set focus to a text box, scan the barcode and the barcode appears in the text box followed by a CR. If …

if you are being prompted for "Forms!f_TopicSelect!cboTopics" then it does not recognise it as an object. To cut to the chase, here is what I think you want to achieve. Create a tabular form to display notes and topics from the notes table using the form wizard. In design view …

You need to use Set when you are assigning objects but not when you are assigning variables.
