Programmatically Reset Form Background From A Picture To A Solid Color?
Nov 13, 2009
How can I programmatically reset my form background from a picture to a solid color. I have no trouble changing it to a picture or even changing it to another picture, but when I try to change it back to a solid color, it won't work.
I have a datagrid view with 8 columns. How do I change the background color for any cell in columns 2-5 where the value equals the value in column 8. For instance:
i'm using VB 2010 and i'm trying to make a transparent images but without success .i draw 2 GIF pictures in Photoshop and save it as transparent.i put that GIF's in 2 pictureboxes on the form and the background of the pictures is really transparent, but when i try to put one picture in the top of the other one, the first picture cover the second one with the background color (and becuase it's transparent it's like the form color)
It detects the color fine and the picture background changes to the color my mouse is pointing at, but when it changes to one of the colors its ment to send me a msg it doesn't..[code]

I want the background of my form to be the same color as the window frame color that the user selects, even if that changes. I selected System->WindowFrame as my background color, but it always remains a dark grey, regardless of what I have my window color set to. How else would I achieve what I want? I assumed I was doing it the correct way. Do I actually need code that gets the system window color and then apply it?
I want when I color a shape ,that color does not wipe the background picture.I want it be transparent not solid :S I tried Opticity property :-/ but it is just for the whole form :icon_sad: ,it does not available for the color.

I can change the backcolour on a form but I want to be able to change the colour making the change the new default color. The book I am using shows this as an example so far: 'show the color dialog and if the user clicks the ok button, 'update the background color of the form if colordialog1.showdialog = windows.forms.dialogresult.ok then me.backcolor = colordialog1.color end if end sub
I've been trying to make an image viewer that keeps top most while I do other things (like typing, etc), so I don't have to hop windows, or sacrifice screen real estate.I made a main form, and a configuration form (opened by pressing o), with options to set the main form's opacity (working), the picture displayed (as the form's backgound picture, not working), and if the main form stays top most or not (working).
Instead, the form just keeps displaying the image I set in the IDE.I first used a picture box to display the picture, which did not work, and decided I didnt need to have a picture box if I set the picture as the form's background picture.I tried looking at what could be going wrong, but couldnt find out much more than the path is being delivered to the main form.I'm working on Vista Home Premium 32bit SP2, VS2003, and here's the code.PS The code links to a D:ath-fin.jpg that I used as the default background picture, and the code is for 2 seperate forms.
