I'm learning VB2008 using the Express edition IDE, and would like to start using the Mercurial SCM. I have a couple of questions:
1. Should I use a single repository for all my tiny projects under C:\VB.Net\, or should I create a repository into each project [code] If using only a single repository, will Mercurial filter changes so I can see only files belonging to a given project?
2. What files/directories can I leave out of Mercury? For instance, here's what VB2008 Express created for a single-form project: [code]
3. Is it possible to avoid the empty \WindowsApplication1\ at the root of a project, so that I don't have to cd into it to find the first actual file (WindowsApplication1.sln)?

I have an old app still written in VB2003 that required some changes, part of that was revamping a menu that isn't behaving.I've deleted it and it doesn't show in the designer but when I start the program there it is, and still not correct.How do I really get rid of it so I can build another one?I'd hate to have to delete the whole MainMenu, this is the 5th in line, that would be a lot of re-creating.

When you edit a cell in a datagrid, how can you "commit" that change if you are still in that current cell? Right now, the DataSet.HasChanges property isn't true UNTIL you leave the current cell. If you don't click on another row, then the property is not true yet. How can I tell it that it is true without physically clicking on another cell?

way to "reset" a tooltip, so you don't have to leave and re-enter a control to make it pop? I have a form that is pretty much entirely taken up by one control. I want to have its ToolTip text change based on which region of the control is being hovered over (which I can do now). I just have to leave the control and re-enter it to make it pop. I'd like to have the Tooltip pop, then if I move the mouse to a different location (still inside the control's bounds) have it pop-able again in the new spot.

I am working on a new assignment. Our instructor wants us to code a shared leave event for three textboxes (txtBox1, txtBox2, txtBox3).I understand how to code the shared event and how to make a generic tbox for it:
Private Sub txtDescription_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtBox1.Leave, txtBox2.Leave, txtBox3.Leave
'generic textbox
Dim txtText As TextBox
txtText = CType(sender, TextBox)
We are told that if the generic textbox contains data and the data has been modified (against the database record), we need to : Determine the name (name property) of the textbox that casued the evend and Determine the value (text property) of that textbox.I know to check to see if anything is in the generic box by the length property, and if it is modified by the modified method, but how do you determine the name and value? Is it a case statement?

I have some validation set on my combobox and it works as it should, but the problem I have is that the user is unable to click on the exit button, or click on the X to close the form until they have entered a valid field - would it be possible to exclude these controls from the validation? So the user can click on exit, or click on the X?
My coding is:
Private Sub Combobox1_Leave(sender As Object, e As System.EventArgs) Handles Combobox1.Leave
If Not Combobox1.Items.Contains(Combobox1.Text) Then

I have a project due tonight and suddenly 2 of my datagridviews are acting funky while the others are fine.
I have 2 tables in an sqlce db. the first is books(id, title, copyright) and the next is publisher(id, name, bookid). I'm writing a vb.net frontend to access the data.
I have data bound datagridviews for both tables. Both have their respective ID columns hidden. The publisher dgv uses a combobox cell style to display the book title in the bookid column. So far so good.
I have suddenly run into a problem where if I have clicked in a cell on the books dgv and then click a cell on another row, the title changes to the id value. The publisher dgv also updates to show the id instead of the title.
It sounds to me like there may be a problem with the booktableadapter or bookbindingsource, but I don't know where to start looking for it. I have a 3rd dgv referencing an unrelated table, and it has no problems. The code for both the working and problematic dgvs are the same (only the control names are different).

I am still in the conceptual(planning) stage so I do not have a code to show as an example.[code]...
Example: A user visits the form, the cursor by default(Tab Order) is in the first TextBox. If the user tries to leave the box without
entering any information an error is displayed. The user cannot leave the TextBox(MaskTextBox) unless they enter valid data.
If the user enters valid data the error message goes off and the user is able to leave to the next TextBox.
I also have a bunch of RadioButtons, CheckBoxes and NUD that I would like the user to play with without trigger the error messages on the TexBoxes. If the user click a check box or radio button, I need the error message to stay off, the error message should only trigger if a user click in a text box and a: Decides to leave without entering data or b: enters a wrong data.
I know other ways to do this, example using a submit button to do this. However is my idea possible? Can you have a field(controls) the validate on leave and click other fields(controls) without triggering it?[code]...

MSDN brings nothing up, so here was my attempt at a work around.
[code]...
Because event leave calls another sub i need the last active control. I have the textbox name txtTime{0} but obviously string is not a control.
So Two questions:
1) can a string value be attached to an existing control if i know it's name? Dim attControl as Control = newTime
2) All this could be avoided in event leave if i could get the left controls name. I have tried sender. tostring etc but nothing returns the textboxs name

There are 2 non-modal windows displayed- 1]Form1 contains a Listbox with a list of forms 2]Form2 is the form which is selected in that list Form2 consists of a Maskedtextbox T1. In the Leave event of T1, the validation of text is done. If the data is invalid, a suitable Messagebox is displayed and Focus is set back to that Maskedtextbox (T1.Focus()).Now, if I enter any invalid data and click on the Listbox in Form1, the following things happen:
1]T1 Leave event is entered, focus being on the Listbox
2]Invalid data message box is displayed
3]Focus is set to T1(T1.Focus()) of Form2
4]After End of event, T1 Leave event is again entered. And now, Focus has changed back again to the Listbox.
5]Again Messagebox is displayed and T1.Focus() is done
The issue is, after step 3(focus set to T1), the focus is reset to the Listbox in Form1. Hence Leave event is entered twice and messagebox is displayed twice.

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.
