I've got users uploading a file, which I then want resize, make a thumbnail
out of, then delete. The image and thumbnail are working fine, but when I
try to delete the image, I get an error: "The process cannot access the file
"c:\inetpub\wwwroot\pictures\1\21_orig.jpg" because it is being used by
another process. "
I'm using the Image.Dispose() method before trying to delete it; how do I
free up this image?
Thanks in advance,

I’m wrote a small DLL that used the FreeImage.DLL (that can be found at

I also wrote a small console application in C++ (unmanaged) that uses the

Now the application, together with the above DLL’s is successfully loading a

Hi,
What is the better way to save image into a database ?
Just save the path into a field or save the image itself ?
I have 20 000 images (~ 10/12 Ko per image ) to save.

Hello,
I am running into a problem with my code and can't seem to figure out the
solution.
I know it has to do with the pciture box control and unloading the image
inthe picture box but I can't seem to figure out the correct way to "unload"
the file.
I have a simple form with a picture box and a button. I am using dir() to
get all the the .tif files and display them in the pciture box. Each time the
button it pressed it displays the...

I am developing an application that possibly opens very large images - bmp,
jpeg, tiff. I have 2 questions:
Language: C#, VS .NET 2003.
1. When the program opens a BMP image, the amount of memory used seems to be
larger for BMP files than JPEGs with the same pixel dimensions. For example,
5200 x 5000 pixels image -- increase in Mem Usage is about 80MB for JPEG, but
200MB for BMP (with Task Manager). The Mem Usage is noted before and...

Hello all,
I am currently implementing a fairly simple algorithm. It scans a
grayscale image, and computes a pixel's new value as a function of its
original value. Two passes are made, first horizontally and second
vertically. The problem I have is that the vertical pass is 3 to 4
times slower than the horizontal, although the code is _exactly_ the
same in both cases?!
The code itself is very simple. There are 2 loops to scan through...

Hello. I have a process that can take a long time and I'm trying to put an
animated gif while the user is waiting.
I added a panel with a picturebox with the image inside. The panel is not
visible when the application starts, but before the process, I make it
visible.
The problem is that while the long process is running, the image doesn't
appear. The panel is empty.

Hi all
Does anybody please know a way to extract an Image from a pdf file and save
it as a TIFF?
I have used a scanner to scan documents which are then placed on a server,
but I need to extract the image of the document (just the first page if
there are multiple pages) and save it as a TIFF so I can then use the
Tesseract OCR to get the text in the image.

hi again to everyone!
I made a simple program(for my VB.Net practice). The program loads an image file to a picturebox upon clicking a button. after loading the image file i have another button to delete the loaded image file from the directory. But I have a problem deleting the image file used by the picturebox even if I set the "PictureBox1.Image = Nothing" before deletion takes place. The error says, "The process cannot access the file...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
