View 5 Repliesway 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.
View 5 RepliesI 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
The leave event fires twice in this example. Tab order for the form controls is set to combobox1, button1, button3 Private Sub ComboBox1_Leave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.Leave
[Code]...
if I enter 'A' in the combobox1 then combobox1 leave event will fire twice any other entry is Ok since the next control to get focus is button2 (in the normal tab order).It seems that if I try to skip the next control (based on the tab order set for the form), the leave event fires twice.
Anyone know why the Mouse_Leave event fires when you don't leave the control with the mouse pointer?Put a large button on a Form so your mouse pointer does not leave it easily.Then try this codeWhen you do, leave the mouse pointer in the middle of the button and then click the button.By the way, if you uncomment the 1st line of code in the Button Click event and comment out the MessageBox, this does not happen.Can someone please explain this behaviour?

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.
View 7 RepliesI'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 want to know how can I leave a space between two columns, so that the entry into the second column start in a given position.
This my code see it:

View 1 RepliesI 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.

View 2 RepliesWhen 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?

View 1 RepliesI used textbox.leave so that when user leave the textbox, it will fire a function.
Under some cases, I would like to disable this textbox.leave event.
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?

View 2 RepliesI 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).
Is there an efficient way to find all the divisors of a number that leave no remainder? And by efficient, I don't mean dividing a number by every other number to see if the remainder is zero.
