If you are using VB.Net 2005 or earlier. It was asked if a control can be made star shaped in this thread. [URL]. Then I have updated my Shape extension method to include a optional third parameter. The 3d parameter is indent percentage or indentPercent. The default is zero so there is no indent. If you indent by say 50% you will get a star shape.
The various ways you can call this extension method are;
'Please note: myControl may be any kind of control
'such as a Button, a PictureBox or whatever.>>
Dim myControl As Control = New PictureBox()
'Defaults to 6 sides with no rotation angle.>>
myControl.Shape()

View 3 RepliesI'm using e.graphics in the Me.Paint event to draw a string in the form. There is a rectangle shape with gradient in the form, and the string is supposed to be drawn on top of the rectangle shape. However, when I run the program, the string is drawn under the rectangle shape, and is therefore invisible... How do I fix this?

I have a mask bitmap (bmpMask) that I am drawing onto a destination bitmap (bmpDest). Both bitmaps have alpha channels but are already full of opaque content. What I want to do is produce transparent areas using GDI+ 'Draw...' methods on bmpMask so that bmpDest shows through when I draw bmpMask over it.Of course gMask.DrawLine(Pens.Transparent, 0, y, wMax, y) causes no change to bmpMask, because GDI+ works as designed and doesn't draw anything when transparent. Even with semitransparent colors, only the r,g,b values of bmpMask's pixels are updated.

I am creating a Windows Form exe using VB2008. The documentation for VB2008 says "Multi-selection is not supported on CheckedListBox". But it works very well in debug mode. I cannot change the properties of the control in the IDE but I can run the following statement (clbProj is a CheckedListBox control) in the load event and it implements the multi-selection on the control.
clbProj.SelectionMode = SelectionMode.MultiSimple
I run many tests in debug mode with this option and it works every time. The program processes every checked item in the list and works as expected.
However, when I compile the program and start the exe, it throws an error saying "Multi-selection is not supported on CheckedListBox".

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..
I know when I draw to the form and add controls I get a flicker effect.If I draw to a picturebox on the form and add controls will the picturebox flicker?

I am trying to write a graphing program that will draw on/in a picturebox during the form_load event. It works if I connect the code to a button event and click the button but the exact same code in the form_load event seems to do nothing. I've tried calling cmdDraw.PerformClick() and cmdDraw_Click() and although the Draw button works when I physically click the button with the mouse, nothing seems to happen when these functions are called during the form_load.

It seems in VB2008 I can only use pens inside a picturebox1_onpaint() subroutine, I can't tell a picturebox what to do from a button_click subroutine or form_load subroutine first and then send the results to a picturebox. I have no control over when the graphics are drawn and from which subroutine. How do I solve this in VB2008 ?
How can i draw a rectangle in picturebox using coordinate(X , Y) and size of rectangle from textbox?
View 7 RepliesIn my application there's a PictureBox with a drawing inside. I implemented a zoom function that works in the following way:
- The user clicks somewhere in the PictureBox, and holds the button down. The program stores the cursor position.
- The user moves the mouse, while still holding the button down. The program draws a rectangle between the original and the current cursor position.
- The user moves the mouse further, while still holding the button down. The program deletes the last rectangle, and draws a new rectangle between the original and the current cursor position.
- The user releases the button. The program deletes the last rectangle, and executes the zooming based on the original and the current cursor position.
My problem is that I could only delete the rectangles by drawing same-sized, background-colored rectangles on top of them. But this also deleting the original drawing inside the PictureBox. Is there a way to draw "removable" rectangles?
I have a simple picturebox, line drawing procedure (call it "DrawTheLine"), which fires ok when I call it from a command button. But when I try to call it from the boot form_load procedure it doesn't work; no lines draw. No errors are raised.
Things I've thought of are:
1. The form_load procedure is not done creating all of the controls on the form, so it can't work with them yet. Doesn't make sense because my drawing call is the last thing in the form_load procedure, and it executes, but the picturebox does not show the lines.
2. Tried Application.DoEvents, but no go.
3. Tried using picturebox.invalidate to force a paint event and "called" the drawing procedure that way, with the appropriate arguments. Again, the procedure "DrawTheLine" fires, but no lines draw to the picturebox.
