ave 40 textboxes in my form. A Combo box is associated to each of them. When users selectform first combo box an arrow should be drawn from fist textbox to the next textbox (next textbox might be next textbox or a textbox in the middle of the form!)I know there will be at least 16 Arrows at the end of each usage.
View 5 RepliesI have a group of textboxes for a tab editor. 6 vertcle, 25 horizonal. ( numeric guitar sheet music) I want to be able to navigate them with the arrow keys. If I number them in chronological order from the bottm left, the up arrow key would be "+1", down arrow key "-1", the left key "-6", & the right arrow key "+6". That way I can navigate any possible way on the array. My question is, "How do I do this in code?". ( I have never had a school coarse of any kind in programming-learning VB Express at home.)
View 11 RepliesI am writing a little 'macro' functionality into my multi-line textbox. All is ok except i don't know how to move the cursor up, or down, lines to simulate pressing the keyboard arrow keys (left and right are no problem). Obviously lines can wrap so using substring may be out?
View 4 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I would like to draw a figure like this. But i do not know how to start drawing it. What i could do is simple mathematics calculation, display something in a label and taking some values from a textbox.

View 2 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

View 2 RepliesI want to change the "a" and "d" to key controls left and right perspectively. and I am having some trouble wiht the key up event. KeyChar works for KeyDown (after I forced it to) but not for KeyUp (even though they share the same things). I finally figured out how to get the picturebox to change its picture, but now I am stuck at this part. getting an animation in, and when im done moving, get the animation back to the idle picture. im also having a little bit of trouble with movement. pictre - as a split second of movement and (space) as a split second of not moving, when i begin moving, lets say it goes this way (there is a space right after the first -, so that was a split second that it stopped and then started continuously started moving again). how can i make it so it goes nice and fluid once you start moving? also, if i were to press any single key while holding A or D down, it either stops and i have to press the key again to move it move or, it goes in the other direction(if I hit a then d, or d then a). and in the key up event, id like it so when the a (or d) key is up, it goes back to the stand animation, and when moving, it goes to the moving animation.

View 3 RepliesSo in winforms, every dropdown combobox has this little arrow thingy to the right that tells the user it's a dropdown, kinda like this:Now how do I figure out how wide that is in pixels? Reason is, I'm using ControlDrawToBitmap, this doesn't draw the text properly for the combo boxes, and I can redraw the contents, I just whack some of the arrows (which are drawn properly).
View 2 RepliesThe feature I'm trying to implement allows the user to press the down-arrow key and "tab" through different features on the form.
