You mean your code works in debug mode and does no in release mode?
If yes, then check with array size and index used.
Typically such errors come in release mode if the memory allocated is not enough.
In debug mode due to extra buffer the problem dont seem to occur.
Check out the size of calibrate_list and max cntr value used.

TY ArtiGujare. I'll double check those items. I googled the error and
found a posting that directed me to a BB. It indicated that there may be
a problem with my machine. Consequently I compiled, jump drived the .exe
to another machine and ran it. No error...(hmmmm) Gonna test a couple more
machines....
Does running in VS - "start w/o debug" execute the app differently than if
you just ran the .exe??????

Not my machine. Generated the error on 3 out of 4 machines.

Thanx so much!!!!! You narrowed it down to a couple of things and as
a result, I tracked it down. Sometimes it just takes someone saying,
"More than likely the error is this. Double/Triple check it."
I had an infinite while loop going. For some reason, cntr was staying
at 1.

Compile your debug buid with /GZ. It may show the error then.

Hello
i want to work with a Cfile Object in a console application
what should i do please
beacause when i declare a CFile Object in my console app
in the shows the error that Cfile is an indeclared identifier.
thank you

CFile is an MFC class.
your console project has to support MFC.
then, include windows.h

Use AppWizard to create a console application that supports MFC. No need to manually include windows.h. This is handled automatically by virtue of it being an MFC application.

-I am creating a program while having the program GUI developed through Windows Form Application (part of VS2005). I have tried to find a tutorial in c++ but haven't been able to find one. I found many in C# but that doesn't really help in c++. I tried morphing some C# code to try to get the c++ code working, but that didn't work. I am trying do develop a test program so I know how to code Windows Foms Applications before I try to do the GUI on the real project.
-I want to be able to have an action happen when a button is clicked here's the code:
<br />
<br />
#include "stdafx.h"<br />
#include "Form1.h"<br />
<br />
using namespace windowsformsapplicationtest;<br />
<br />
[STAThreadAttribute]<br />
int main(array<System::String ^> ^args)<br />
{<br />
Application::EnableVisualStyles();<br />
Application::SetCompatibleTextRenderingDefault(false); <br />
<br />
Application::Run(gcnew Form1());<br />
<br />
<br />
Form1::button1.Click=Application::Exit();<br />
<br />
return 0;<br />
}
When I try to compile this code I get the following error:
.\windows forms application test.cpp(20) : error C2228: left of '.Click' must have class/struct/union
Ind have tried various variations of Form1::button1.Click and don't have a clue what to try anymore, so hopefully someone can help me! What am I doing wrong? How can I fix it?

In case anyone else hase the same problem later on, I finally (finally after lots of effort) found this.[^]

try attaching an event function, which the exit inside of that function.
This is why I recommended a tutorial on "Visual C++" not just on C++ or MFC, etc. You will find in the button properties how to add an event function to the putton press, then fill that function with the actual code to what is needed. It will be easier if you learn what the tools do for you, and if you read the code it helps teach you what you need to write yourself.

don't hold your breath or bet your salary on it.... I use visual C++ for OpenGL, not for GUI. I know the process, not the specifics.

Ok, I won't hold my breath, but I am trying it out very soon
Hopefully the program will work

I have a class A in a dialog application.
A thread X is running in this class. However, i would like to update a member var in class A.
In order to have access to this member var from thread X, i did a static cast like CClassA * pClassA = static_cast<cclassa*>
I know that the above is wrong but, how can i do this?
|
|
|
|
|
Correct.
pass address of instance of class A to thread X parameter.

So it would look like:
CClassA pClassA = static_cast<cclassa*>(pClassA);
|
|
|
|
|
x *y = reinterpret_cast<x *>(z)

For some reason, images I insert into a list control (whether main item or subitem), always seem to have a white background, and if I change the row color for example, it looks a bit hokey, same with when they are highlighted.
I'm using a transparent image list for the images, which work fine everywhere else where transparency is required, like buttons, etc.
Anybody know any way around this behavior, other than owner draw?
Thanx,
Rick

When you create the CImageList used to store the various icons for the CListCtrl you need to setup a mask for it at the same time, check the documentation for CImageList:Create[^] for more details.

It's already masked. It just seems the list control is painting the background in the color it likes, otherwise I would see bright green.
Code for the image list looks like this:
<br />
m_ImageList.Create(16, 17, ILC_COLOR32 | ILC_MASK, 1, 20);<br />
m_ImageListBmp.LoadBitmap(IDB_LISTIMAGES);<br />
m_ImageList.Add(&m_ImageListBmp, BRGREEN);<br />
BRGREEN is the color I use for transparency.
