May 24, 2012
In my form I have a text box (txtJobNo) , a Find button and a dtagridview to display the record for a unique JobNumber. Everything works fine to retrieve data, my problem is the display part in the datagrid view, it replaced the first record. I want to keep all records in place until I am done and then insert all those records in a new table. Please HELP. Please find my code below:

I need to record the screen when my user clicks start, and stop recording when he clicks stop.I've searched for a while on this subject, and I have found nothing.I want to do this without adding any files to my project, I just want to use some built in function in Visual Basic, and start recording, or even take a snapshot and add it to an AVI file or something...These are some sites I have found:

This code is in VB6, but I am not sure how to even start using it?

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

I am working on a Text editor. The problem I have come to, is that when a user clicks a button, I want all the text to be displayed on one line. The reason for this is I am having problems being able to upload CSV email files on a website I am working on, because the format isn't like email, email, email, email. Instead it is like
email,
email,
email,
So I have written a program that will format it. Only It still isn't working. I need it to recognise when there is a ".com," or something.

I'm running a survey to count how many times a user clicks the left mouse button. But the mouse click applies outside of the form, even applies to clicking start or other locations of the of the PC when the form has been minimized with a NotifyIcon. I know how to count the mouse clicks within a form but not outside the form. Somehow I feel I need to use a timer event but need it to apply outside the form. The timer tick event doesn't have a e.button event or mouse down event or mouse click for that matter. Whats a good way to get this function to apply outside the form?

I'm using VB2008 express. idea for a D&D application. So I wrote something and it works, but it's not coded like I want. Here's the program if you want to see it in operation: [URL]
Here's the problem I have. I want a message box to pop up if no dice are selected and the user clicks the roll button. So far the only way I have been able to accomplish this is to put the same code under each radio button:
Code:
RolledValueTextBox.Visible = True
Label1.Visible = True
Label2.Visible = True
YesRadioButton.Visible = True
NoRadioButton.Visible = True
I want to have this code only once. But If I put it outside of the If/Then bracket and no dice are selected, the msgbox pops up but also the buttons that I want to remain hidden until dice are chosen pop up. How do I get the msg box to pop up and stop...don't execute any more code.
Heres' the code so far. trying to keep it relatively simple:
Code:
Private Sub RollButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RollButton.Click
'see which radio button is checked and display random number accordingly
If TwentySidedRadioButton.Checked Then
RolledValueTextBox.Text = GenerateRandom.Next(1, 20)

If a user clicks the blank row at the bottom of a DataGridView and moves focus away from the DataGridView, the row click in now is in a state that indicates a change is made to that row.
Is it possible to tell the DataGridView to un-mark this row as being changed?
Is it possible to reset this row when focus is off the DataGridView?
We are using the following event handler to alert the user if the Invoiced On is left blank:
Private Sub dataGridViewPayments_CellValidating(ByVal sender As Object, _
ByVal e As DataGridViewCellValidatingEventArgs) _
Handles DataGridViewPayments.CellValidating
[Code].....
Looks like we need a way to stop this from executing if the user simply clicks in the grid then clicks somewhere else in the form.

I have a VB.NET 2010 Forms Application which includes a form with a textbox, and two buttons which I call from the main form using .ShowDialog
I've messed with something such that I can no longer prevent the dialog from closing when the user clicks the Ok button but has entered invalid information.
Here is the handler for the OK button's click event:

I have a problem with a Save button on a toolbar firing the click event twice if the user double clicks the button as opposed to single clicking.Disabling the double click on the toolbar itself seems to make no difference as it is the actual save button that is being clicked twice.I have tried setting a Boolean to stop the event firing twice but it is just too quick!I didn't have this problem with my code before as the server call was not async... and reverting back is not really an option.
My code is as follows:
Protected Sub tlbOrdQuot_ButonClick(ByVal sender
As Object,
ByVal e As System.Windows.Forms.ToolBarButtonClickEventArgs)
Handles tlbOrdQuot.ButtonClick

I want to know if VB.Net already has a control like this before I start wasting time building my own. I have a DataGridView that shows the row error symbol in the RowHeader if the update to the database is unsuccessful for that row. Currently, if you hover the mouse over the error icon it will show a default tool tip to display the error text.I would like the user to left-click the RowHeader and a small popup window will show the error text. Then when the user clicks somewhere other than the popup window it will disappear just like a context menu. do I need to build a form with no borders that has a large textbox in it, then setup an event so when the form loses focus it closes? Or does a context menu strip have the ability to support a large textbox? Or do I use a splash screen?

how to get the DataGridView CellMouseDoubleClick to fire when a user double clicks on a DGV cell.I currently have both DGV.CellMouseClick & DGV.CellMouseDoubleClick implimented in my code.The DGV.CellMouseDoubleClick never fires and the DGV.CellMouseClick always fires. The only exception is when I position the cursor between DGV cells and get the double arrow. If I double click with the double arrow then I get the DGV.CellMouseDoubleClick to fire.I need to take different actions for users RT-Click, RT-Dbl-Click, LT-Click and LT-Dbl-Click.

I add a button to a form each time the user clicks a menu option as:
[Code]....
This draws a small blue line at the bottom of the button to show it is highlighted. Just like the mouseoverbackcolor property on a button except this will draw the line. It works fine until you slide the mouse very fast between the buttons. It is as if the mouseleave event doesnt always fire.

In my application, the user clicks a single button and the program displays each network adapter description into a message box and then gets all the ip info for the workstation and places it into a text file and opens that text for reading. What I would really like for it to do would be to display all the network adapters into a single messagebox instead of messagebox for every adapter like it is currently doing. Here is the code I have on that button. Let me know if anyone needs more info or has any questions:

On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip
