Hi,
I get an interesting question. I program an MDI that each
JInternalFrame will show an image of 1700x1500. I limit that 2
JInteralFrames (and thus 2 images) can be opened at most. When users
try to open third image, the JInternalFrame on top will be replaced
with the new image.
a) I open 2 images (thus show 2 JInternalFrame). Then when I try to
open third image, the image on top is replaced and there is no
java.lang.outofmemory.
b) I...

Hi,
My name is Roby Eisenbraun Martins, I am a C++, VB and NET developer.
I am working with a NET 2002 project right now and I am receiving this
uncommon "OutOfMemory" error message when I try to load a form object ( new
frmMain() ).
In debug mode, the "Load" form method is executed but it crashes when it
tries to set a DataTable from a DataSet in a local variable. Actually the
object value in debug mode is equal to nothing.

I am using a method that was described as the best for avoiding memory
leaks when using MS Picture boxes. The main idea was to use a variable
to load the image from file and then assign the picture box image to
that variable like so:
Dim img as BitMap ' (have tried BitMap and Image)
img = Image.FromFile(OFD.FileName)
PictureBox1.Image = img
This has worked great with my photo album creator as my memory leaks

before. Since we use a set of tools to generate most of the basic
code. Every table in the database related to an object in the

object of the application, the tool generates methods for basic
database operations like insert, delete, update,...

Hi Guys,
I have a real serious problem that stoped me doing any progress in my project.
in one of my webpages I have a wizard of more then 13 pages and in every
page some Ajax controls, textboxes, dropdownlists, about 4 panels, where
every page in my wizard have almost the same controls; so all what I had to
do is copy the controls from a wizard page then paste it to next one and just
change the controls names and it was going all fine...

I am using a listview to hold a bunch of binary data (approx 25 rows
and 700 cols). I have a compare function that compares each row's bit
at a certain column. i then color the background of each cell as a
result (green for equal value, red for unequal value). This colors
each of the 700 columns either green or red.
now, the problem: when i scroll horizontally to look at all of the
columns, i will periodically run into a horrible...

positioning on the map) over the last PictureBox. The problem i'm
having, the background for this second PictureBox only stays
transparent when...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
