View 3 RepliesI was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
View 2 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean

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.

I'm making the transition from VB6 to VB2008 and I'm having difficulty finding the equivalent to[code]...
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.
This code is used to demonstrate drawing a blue border around a picture box...(I've numbered the lines so I can refer to them below
1 Dim objGraphics As Graphics
2 objGraphics = Me.CreateGraphics
3 objGraphics.Clear(SystemColors.Control)

Regarding line 1, the author says, "To instantiate an object in code, you create a variable that holds a reference to an instantiated object".!Regarding line 2, he says "the CreateGraphics method is pretty complicated, but for now, just know that it instantiates a new object that represents the client area of the current form".So now I have two new instances, the one from line 1 - an instance of a graphics object, and this one from line 2 representing the client area of the form.The rest of it is pretty clear; But Why can't I draw the rectangle around the picturebox itself? Why do I have to draw it around the "instance" of the picture box?

In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
View 4 RepliesBasically Im converting my old VB6 chip8 emulator into Vs2010 version, so far everything works except the drawing routine.In Vb6 it was easy, simply pict1.line(x1,y1)-(x2,y2),vbwhite, BF etc..I could write to the picture box directly within a different sub called from main() and also call the form refresh etc.In Vb2010 it seems entirely different, you create a graphics object.Dim g as graphics Then assign it to an object with the create graphics method g=picturebox1.creategraphics then use g.drawline etc.. <<< this normally goes in the paint event of the object.The problem im having is that nothing displays until the paint event, which is not how my code works.Basically the emulator procedure framework is:-
LoadRom
Initialise stuff
Emulate
-Fetch opcodes
