Moves The Focus To The Next Tabstop Candidate?
May 28, 2009
In my keydown event handler, I am trapping when an ENTER is pressed and i want to advance to the next tab stop as is it was a TAB presses.I am currently using "SendKeys("{TAB"})" and this works but it is a sloppy way to do buisness, as there may be some typeahead keystrokes in the keyboard buffer.
I have also tried going through the controls collection off the form object, but it is too complicated as i am using containers within containers.Another consideration that TAB processing must be taking into consideration is "what if the tabindex is equal to the current tab stop? what if the next tab stop has tabstop=FALSE or is not enabled or not visible.The sendkeys approach handles all these issues but is a dirty approach and has keyboard buffer event processing quirks.There must be a method off some object somewhere that simply moves the focus to the next tabstop candidate.

I'm working on an application to write reports for the work I do. I have a Grid filled with Textboxes inside a Scrollviewer to input data for the report. I am using the arrow keys to navigate around the grid. The focus moves to the expected Textbox when the arrow keys are pressed but if I press any other key it is immediately followed by a Tab to the next Textbox. Even a Tab is followed by another Tab. Following is the code I use for the navigation.
Private Sub svReportPage_KeyUp(ByVal sender As System.Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles svReportPage.KeyUp
Dim focusDirection As FocusNavigationDirection
If e.Key = Key.Right Then focusDirection = FocusNavigationDirection.Right
If e.Key = Key.Left Then focusDirection = FocusNavigationDirection.Left

I have a DataGridView control with 10 columns, some columns that are just informational, populated by my visual basic program. The user is not supposed to be able to change the data in these columns, or even tab or mouse to them. I can set the column ReadOnly property, but the tab and mouse still allow that column to be selected. The last five columns of the grid need to be disabled from tabbing. For example I have 10 columns. When user tabs thru grid to the fifth column I want the focus to go next row, second column.

I have a form that has 13 groupboxes each with 6 radio buttons in them. I want to be able to tab through the left-most radio button in order. At load time, the left-most radiobutton in the top groupbox is checked. The only way I found to have this load unchecked is by setting it using a timer, but this makes it so that that radiobutton can't be tabbed to at all.

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.

I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

How do I make a picture box follow a designated pathway. I have made a game where I have several picture boxes that follow each other. and want on of the trails to be able to do its own course. I have noticed that picturebox.left = picturebox.left + 10 works only for going left but picturebox.right = picturebox.right + 10 it saids read only. so I tried doing minus 10, though i don't know a condition how to do it. like how do it make it turn around when it's 10 from the boarder?

I want to make a game where the playing pieces can move around. When I click on a playing piece it shows all available moves were I can go like this:
Red represents legal moves and dark gray represents a wall.
I have created a grid and buttons in it. When I click on a button, I subtract or add the available step count to the button index in the grid. For example if my piece can move 3 places, I subtract 3 from the index of the button and get the available position to the left of the piece. Then I do the same for all other directions. It looks something like this:
For each i as button in grid
Select case grid.indexof(i)
Case grid.getindex(currentPlayingPiece) - 3 'Left
[Code]...
Using this method it is very slow and cumbersome to get all available moves and not intuitive to get top and bottom moves. Also if there is a wall in the way and behind there's a available spot it shows that I can move to it.

How do you make a program that moves your cursor to a selected color? So you start the program and then the cursor will auto move to the color red (if that is signified).

I want to make an application that moves all files from 1 zip to another and deletes a folder.
It is a Minecraft mod manager, so i wanna move all files from one zip containing the mod, to the minecraft.jar (which is a zip with another extension) overwriting all files. Also, it should delete the META-INF folder in minecraft.jar to prevent black-screening.

I'm really a novice and I'm trying to draw a thermometer that moves up or down with temp change. I created a second form on my project for the thermometer and access it using Thermometer.Showdialog((). Then on the thermometer form, I'm using this code:
Private Sub ThermometerForm_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
Dim g As Graphics = e.Graphics
[Code].....
It works great and shows the red moving up though the rectangle. Problem is that when it's finished the loop (33 seconds) and I click anywhere on the form it apparently enters the loop again, then hangs so I have to manually close it from Windows.

I have a VB .NET form with a splitter control on it, and I want to save its position between program runs. I am currently handling the SplitterMoved event and storing the SplitterDistance. Then on program startup, I set the SplitterDistance to the saved value.
However, sometimes the program resizes the splitter, raising the SplitterMoved event and overwriting my saved distance. I have several splitters over multiple tabs in a tab control, and any time the user goes to a new tab for the first time, the SplitterMoved event fires.Is there an event I can use that will only fire when the user moves the splitter, and not when the program moves the splitter? I tried MouseUp, but when that event fires, the new SplitterDistance is not yet set.
