Form Box Does Not Display New Background Picture Upon Image.FromFile ?
May 2, 2010I'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.

Differences PictureBox.ImageLocation And Image.FromFile()
Jun 20, 2009I am a little bit confused about PictureBox.ImageLocation and PictureBox.Image = Image.FromFile().
The problem: If I use PictureBox.Image = Image.FromFile() then I am not able to do something with the file unless I dispose the PictureBox (which I most likely don't want to do).
If I use PictureBox.ImageLocation instead, I get the same result but I am still able to delete / move / overwrite the picture file.
So, just to get confused entirely: What are the differences between PictureBox.ImageLocation and Image.FromFile? When should I use the first, when should I use the second?Listing SPEC's is not a review !!! :-)

Use The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?
Dec 18, 2010I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

16 Color Bitmap Image And Interpert?
Apr 2, 2010I need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.
I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.
I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.

Bitmap / Image Manipulation Effects / Methods?
Apr 18, 2012Back when I used to use an 8 bit home computer I dabbled in machine code with an old version of BASIC which allowed you to POKE values into memory and then call the 1st memory location to execute that code. I used the equivalent HEX values for the processor which ran a series of ROR ( ROtate Right ) or ROL ( ROtate Left )commands through the carry bit as each line of the bitmap consisted of a series of bytes which were an 8 bit BYTE followed by the next BYTE in memory. The effects that I manage to create "in assembly language" as it were:
Scroll leftScroll right By manipulating full bytes in memory I created routines to:Flip the image horizontallyFlip the image verticallyTurn the image upside down Anyway, if you were to try this with the BASIC equivalent to GET and SET pixels, obviously the BASIC was a LOT slower. I am also interested in creating animated bitmaps from one or two images such as the following:Page turn effect.Sliding-in of an image in any direction.Ripple effect.Scratch effect.
How To Create A Bitmap Image Using A Text File
Jan 9, 2010I am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90
[Code]....
The first step will be reading the data, so I created some VB codes:
Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.
' If the user clicked OK in the dialog and ' an image file was selected, open it.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.
[Code]...
The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:

VS 2008 Search A Bitmap For A Similar Image
Jun 24, 2010I am attempting to create a class library that can either search a bitmap to determine whether or not it contains an exact match to a second bitmap or if it contains a partial match. Currently it only returns true if i search the image for itself or if the sensitivity is below around 15%, even when i search with an image that i know should return true. The images I am using are simply a screenshot saved in paint and a section of that first screenshot also saved in paint. Here is my current .dll coding for VB 2008 Express

VS 2008 Small Bitmap From A Larger Image?
Dec 17, 2009I am trying to get a small bitmap from a larger image. something like
Dim bmp As New Bitmap(PictureBox2.Image)
However this just gets the entire picture not just a portion of it, I would like to do something like this where I can specify the starting and stoping points
Dim bmp As New Bitmap(PictureBox2.Image, StartX, StartY, EndX, EndY)
I would also like to take these smaller images and paste them into a single larger image. Is there any way to paste it in starting a a certain point. Such as
paste bmp into Picture1 (StartX, StartY)
How To Display A Bitmap On Form, And Then Remove It At Times, And Put It Back Again
May 13, 2009I want to display a bitmap on my form, and then remove it at times, and put it back again.
I have the Bitmap in my resources folder.in my form properties, it is selected as background image.
somewhere in my code I set the background image to = nothing (that makes it disappear) but every time I try to bring it back, I get file not found.I got it to display when I hard-coded the entire path and filename.[code..]
Obviously, when I publish and distribute to clients, the file won't be there.[code...]
Bitmap Effects (Firmware 2.0) Change The Source Of An Image In WPF
Sep 2, 2009I think that changing from WinForms to WPF just because the blur effect is easier to do in WPF is the stupiest thing i can do right now it took me time to understand how the windows form application works i dont even how change the source of an image in WPF so here we are again. how to blur a speciefied image using CODE ONLY ?
See what im trying to do:
1. Imagine that you turn on your pc. takes some time to load.
2. Finally for the first time you are on the desktop.
3. Before you do something after every icon is loaded my program
takes a picture of the desktop and blurs it.
4. then it runs fullscreen showing the desktop behind as blurred and
not giving you access to the desktop.
5. a login/register border pops up
6. if you login the program closes if you dont it stays there
waiting for you to login or register.
I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again. What i need to learn:
1. How to take a screenshot of my program (only yhe content of the window) [Progress: 1% (cause i know how to take a screenshot of the desktop)]
2. How to blur that image [Progress: 100%]
No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it?
