Using a blank form I draw simple colored shapes to the form(x800 - y600 @ x0 - y0).
I'm using a picturebox(x800 - y600 @ x0 - y0), how do I copy whats on the form to the picturebox?
I want a mirror image copy.
Also, how do I copy from picturebox to form?
I know how to copy a bitmap to a picturebox.image but how do I copy the bitmap to the form?
Example:
I want to create a form 1600x1200 and put a 1600x1200 image on the form to cover the entire surface.
Then I want to put several pictureboxes 256x40 (Tool Bars) at different locations on the form.
If pictureboxA is at x32, y32 on the form, I want to copy from the form at x32, y32 256x40 to the picturebox.image then draw
the buttons on the pictureboxA.
I know how to load a .jpg or .bmp to the form from a file. This won't work for my purpose.
If there is no fix for this then the only thing I could do would be to create the bitmap then save it to a file, then reload the file to the form. I want to avoid this... It takes up time :(
I have multiple picturebox controls in my form. Both of them contain an image with a transparent background. I want them to be on top of each other. I've already set their BackColor property to Transparent, but when I place one on top of the other one, the following happens: [URL]. How can I make them transparent while they are on top of each other?

My app has scrolling images in the background and a picturebox on top. The image in the picturebox has transparent parts. How can It so that the transparent parts show whatever is belo the picture box, not the form background?

I have a little piece of code which saves a certain Bitmap to a JPG image. The Bitmap is "composed like this" ( Ppiechart is a picturebox):[code]So After it is declared I start to do some drawing on this bitmap. And then I want to save it like this:[code]So this saves the image. But the problem is that the background of the image turns black when I open the file on my PC.The background of the Bitmap in the program itself is white. So does anybody have an idea what may cause this? Do I have to declare a color for the "mybitmap"?

And is it even possible to do a vb6 style implementation? As I see it, this will clone the picture image while the vb6 implementation will just read directly off the image? and is lockbits like getdibits? I need to process 60 bitmap images of about 200pix by 200pix every second.

Ok well im making a game maker =) but there are some problems that need to be fixed =(. Ok well the first one is bitmap, It takes up to make space and it has a size limit. Is there something like bitmap that will let me draw images onto a picturebox or something like that with unlimeted space and it deos not to up much memory space? cause there are some game makers with huge maps and they used visual c++ but how i dont know
View 13 RepliesEdit: Fixed, I created a compatibleDC for the graphics object, and a handle for the bitmap (using b.gethbitmap), then used the SelectObject function inside GDI to select those two, and used the compatibleDC instead of hDc in the BitBlt function I've been trying to draw a bitmap to the screen (device 0), however I have encountered a problem copying the graphics using BitBlt.
Initially, I was drawing directly to the desktop using SetPixel (gdi32), but it was slow, so now I am setting the pixels of a bitmap object and then creating graphics from that object, and copying the hdc of the graphics to the screen.My guess is that I am adding the HDC of the graphics object to an intptr, which essentially gives me the HDC of the container of the graphics object, which is not what I need. However even so, I have not found any information on how I could copy a bitmap to a device other than using BitBlt.
This is my current code (Windows forms app, textbox, button) The textbox is the device to copy to, and the button starts it. For testing purposes, set the textbox text to 0, and press the button. You should see a black box (50x50px) in the top left corner of your screen. The colour should be blue if it is working correctly:
Public Class Form1
Declare Function GetDC Lib "user32.dll" (ByVal hwnd As Int32) As Int32
Declare Function ReleaseDC Lib "user32.dll" (ByVal hwnd As Int32, ByVal hdc As Int32) As Int32
[code]....
The way it works is it calls the function setpx, given a location and color from within a loop iterating through all of the pixels in a box (50x50 in my code). The setpx function will then call the setpixel fuction on a bitmap b. This part is working fine.Next, it will define a graphics object g from the bitmap, and I use BitBlt to copy g's hdc (g.gethdc) to the screen. This is not working correctly?
I am trying to take a snapshot, or a copy of a control, for a bitmap. I'm wanting to do this to a listbox, but part of the listbox may be hidden.On the mouse_down event I need to get the snapshot of the whole listbox (even though parts may be hidden behind other controls, I need the whole listbox) and draw it to the screen in the same location as the original listbox (but the hidden parts still stay hidden behind the other controls on the bitmap).
On the mouse_move event I need to move the snapshot up/down based on mouse movement. This also moves the listbox up/down and this code is done. I will just move the snapshot of the listbox the same way as the original listbox.On the mouse_up event, I will dispose the bitmap and display the original listbox again.
I am doing this because moving a listbox up/down is really messy. It's a custom drawn listbox and looks horrible moving, so I figured if I could snapshot it, move the bitmap while visible, and listbox behind the scenes, it will flow smoothly and no one would notice I am scrolling a bitmap instead.
Double buffering the form and listbox didn't help . I've done some graphics.drawstring before, but not much on other graphics.
I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.

I have a picturebox with a pic in it, and I have a label on top of the picture.
I want the background of the the label to be transparent, so I set it's background prop to transparent and it's parent to the picturebox. I do this on form load, but for some reason the label entirely disappears once the form loads?
I'm trying to print the selection of my picturebox as the background of the image. I can get the image to show, but it's not the height and width of the background.
