My app deals with football, and the line of scrimmage. There is an additional line, called the line to gain, used for showing where a first down is earned. I'd like to have a trackbar with two arrow on it... one for the Line of Scrimmage, and the other for the Line to Gain.
View 6 RepliesI've created a class for my game and I would like to use the arrows key to control an object on screen.
However since this is the keyDown event I've put it in the main form -form1 But it says that .Left is not part of my class since I am trying to put this on the object that was created by the class. If I put this code in my class it says that event KeyDown can not be found because it is obviously but of the form...

I am building a really complex program, and the only thing that i cannot make work right is the menu.The menu is basicaly 13 textboxes:
-txtMenu1
-txtMenu2
_txtMenu3
There is also a cursor next to the menu with up/down end enter button.When I click the down button it moves the selector one space down and up moves it up..The problem is when i click the down arrow it just moves the selector one space down, when i click it again it does not do anything. Same thing with the up arrow.The code for the down button is and the text boxes tab is in order from 1 to 13.When I reach the end (txtMenu13) and click down arrow, the selector goes back to txtMenu1. I need the selector to be blocked there on txtMenu13 so the user has to use the up arrow to go back to txtMenu1. The same thing when the user reaches txtMenu1 and tries to go up one more, he should not be able to do it.

View 4 RepliesI'm trying to sendkeys to a vt320 terminal, all keys work fine BUT the arrow keys.
For some reason which I obviously don't know, when I
sendkeys.sendwait("{DOWN}")
The terminal shows the number "2" instead. (The equivalent number on the number PAD)
If I send "{UP}" it displays the number 8. (numpad as well)
Code:

p = Process.GetProcessesByName("k95")(0)
AppActivate(p.MainWindowTitle)

I draw my lines with arrows:
mypen.StartCap = Drawing.Drawing2D.LineCap.ArrowAnchor mypen.EndCap = Drawing.Drawing2D.LineCap.ArrowAnchor but I want a bigger (custom) arrows in start and and of line. It's not clear how to do. Perhaps with:
mypen.StartCap = Drawing.Drawing2D.LineCap.Custom Onenew
Trying to create a custom button to reside on the desktop at:
Me.Height = PictureBox1.Height
Me.Width = PictureBox1.Width
Me.Top = My.Computer.Screen.WorkingArea.Height - Me.Height
Me.Left = My.Computer.Screen.WorkingArea.Width - Me.Width
The trouble is all the arrows point to right, and the menus open variably depending on size.
Is there anyway to make the arrows point left and make all menus open to left in same direction?
Also, Is it possible to make the width of my form autoresize to the size of a label and the image box, while keeping the imagebox at the bottom right of the screen showing the populated label to the left?
I have just made a simple application with a questionnaire. The questionnaire has all 40 questions in the same page (that was one of the specifications) which makes for quite a long form. On top of that, each question has its own group box and each group box has 4 radio buttons for the possible answers (in total 160 radio buttons).
I want the user to be able to scroll down using the up/down arrow keys. However, if he has just selected an answer, pressing the down key will only change the selected radio button (as is the expected behavior of a radio button).
How do I disable the selection of a radio button through the up/down arrows?
I am using VB .NET. I want to know how to make the scroll-up and down arrows visible for my text boxes if the user wishes to enter more lines of text than the size of the text box can take. I would like the user to be able to scroll up and down after he/she has entered all the text.
How do I activate this property - should I be using some other control other than a text box for this?
I have code to create a listbox and populate it, and would like the box to behave like it does when clicked, e.g. if you CLICK on "a" you see it blue and can press the down arrow to move down to "b". how do I achieve this programmatically?

I have a fairly simple VScrollbar problem: the Scroll event triggers when ANY arrow key is pushed, including left and right... I need it to trigger only when up/down arrow keys are pushed (which, I hope, is the default behaviour).
Essentially all I do is declare a VScroll As System.Windows.Form.VScrollBar and later I have a Private Sub VScrollBar_Scroll (...) Handles VScroll.Scroll that manages the event.
I noticed also that the left/right arrow scrolling is by a smaller increment than the up/down scrolling. All of this seems to happen in a very "black box" kind of way, I can't find any way of determining what should trigger the scroll event.
I'm using a datepicker for a field on my form, but the arrows are not visible. If I go to the location where they supposed to be, I can click them to change the month, but the arrows themselves are not visible.
View 1 Repliesin my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

Im building a, lets say kiosk, that has only one form of input and that is a keyboard. I've got an up/down/left/right arrows and the enter button. I have a form that needs to have hundreds of buttons. I've arranged all my buttons in a giant grid and want the user to use the arrows to navigate through the buttons. The button that is 'highlighted', lack of a better term, has different colors so we know which button we currently are on. So when the user hits the down arrow the button below the current button gets highlighted. My issue is that when the user hits the left and right arrows the 'cursor' doesnt move left and right it moves up and down.
The left and right arrows follow the tabindex sequence.
I need to identify when a user clicks one of the updown arrows in a datetimepicker. Can that be done?ValueChanged event occurs whether the user clicks an arrow or if the value was changed programatically. I need to determine which method was used.
View 9 RepliesWe have a winform application using Oracle DataAccessClient.There is a gridview and textboxes where we when we click on a row we can populate the textboxes to show more of the data so the user does not have to scroll horizontally.The code that does this is in the cell click event. We want to also do this if the user presses the up or down arrow. We put the code in the PreviewKeyDown event but we are getting the row that had the focus rather than the row that has the current arrow pointing to it. We searched the web at a lot of forums but we can not seem to locate how to do it. How do we move the focus to the row the arrow is pointing to in the grid? [code]

View 7 Repliesknow the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?
