I created a DetailView of a DataTable in a Form. This also created a BindingNavigator and all of this works fine.However, one TextBox in the Form shows the LangaugeCode and I'd like to use my refLanguage DataTable to show the LanguageName instead. How do I go about doing that?
View 5 RepliesI am working on supplier maintenance file. From mainmenu, opening first form shows records on datagridview through databinding. Clicking add new record, i fired a second form as my data entry with detail view through databinding, minus navigational buttons. I left the delete and save button only. Once through data entry, i save it on server. My problem is, how can i reflect the added record on the first form while i am on my second form? I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.

View 2 RepliesI have a datatable that was created with the dataset designer. I have it bound to my datagridview. All the columns are set up the way I want, etc. I am performing a SQL operation at runtime, so I can create SQL statements dynamically rather than creating them with the designer. When I try to fill the existing datatable, I get no results. There is no error, but the data i should be seeing in the DGV is not there. However, if I fill a dataset that is created in code at runtime, and then set table(0) of that dataset as the DGV's datasource, the data displays as it should.

If you want a instance of an object to be created when a form loads or another class is created, you have two options:
Public class example
private IAmAObject As IAmAObject
public sub new()
[CODE]...
Or like this:
public class example
private IAmAObject as new IAmAObject
public sub new()
[CODE]...
I always use the first one. It's more type work but I think it's neater. How about you people and is there any real difference between the two?

I have 2 forms main_frm and copying_frm. In main_frm, there is a list view that is populated with file names. The user then clicks save and all the files in the list are copied to a folder that they choose using a folder browser dialog. When this happens, I do copying_frm.ShowDialog() to display the copying_frm. The copying_frm contains a progress bar and a cancel button. I can get the progress bar to indicate how much has been copied. But that freezes up the application. To get around this, I create a new thread (called copyingThread) that copies the files. When that thread runs though, it can't access the waitingList_lvw in main_frm. For example, in the function that the copyingThread executes, if I have this line of code: MsgBox(main_frm.waitingList_lvw.Items.Count.ToString()) the result is 0. Also, I don't get any errors and no files are copied. How do I access waitingList_lvw in main_frm from a thread called copyThread that was created in copying_frm?

Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.
