When I use Image::GetThumbnailImage to get a thumbnail from a PNG file, the background color becomes black, it's white in the original one. And no such a problem about JPG/BMP files.
How to solve it?
Thanks a lot.

Is it white or transparent?
You may need to create your own thumbnail image by creating
a Bitmap of the appropriate pixel format and using a Graphics
object created from that Bitmap, use DrawImage() to draw the
source image on the thumbnail image.
BTW - GDI+ will not preserve transparency if you save the thumbnail
image to a png file. I think only 32-bit ARGB TIFF files preserve
transparency.

Hi,
I'm having a problem with the caret in my windowless control (created in part with the CFlashWnd object in an article by Makarov Igor.) If I click in a text region on my control, the caret does not appear. However, if I open any other application's window or click on the desktop (anything to shift the focus from my app to another), the caret suddenly appears in the windowless text region.
Has anyone seen this behavior? How can I fix this problem?
Thanks,
Brian

Hi there,
I am new to C++. My job is to recompile a c++ project from VC 6 and Ultimate Grid (Version from 1999?) to VC 2005 and Ultimate Grid 7.2
when compiling, I get the following Linker errors:
<code>

Any ideas?

Hi Everyone,
I have created one application for compiling and executing a 'C' source file. In my application i have created one button for compiling as well as executing (This single button will do both compilation and execution operations). I want to create one more button for stoping (terminating / killing the process) the compilation or execution process(i don't know while clicking this button whether my application is in compilation or execution phase).
Please suggest me how can i handle this or what code i have to write for this new button ???
Thanks in advance
Sanjeeva Kumar.

Did you really make a C compiler? That's amazing!!!

Don't be so flippant, it's probably urgent.

Sure - that beast is probably leaking memory, and he has only so many minutes left to stop it!

You're right. But I was quite impressed by the new compiler-without-linker technology.

What does your button-click handler look like?

weird ...
You should know, because you start your "execution" after the compilation is done.
When the compilation is running, set a flag, when it's finish set another flag, when the execution start, set another flag.
so, when you click on your "termination/killing" button, you just have to check the flag to know if you need to stop the compilation or
kill the process.

On the handler of the first button you can set a global variable (declared in theApp or inside the class where you are working (possibly the same dialog)) to true, and then once you press the second button you can check the state of that variable. Of course you should revert the state of that variable to false once the compiler has finished it's work...
Somehow I have a feeling that the question (how to know if you have pressed a button) and the job done (a compiler) are no matching very well...

I am using one boolean variable(Initially it is false). In the code of second button i am initializing this variable to true. In the first button code, after finishing every phase(i.e, after compilation, linking and execution) i am checking whether this boolean variable is true or false. If this boolean variable is true then i am returning the control(return statement).
Now the problem is when my application is executing the code behind the first button i am unable to click the second button.
what code i should write for clicking the second button, when first button is performing its operation ???
Thanks in advance

Haven't you read on multiple threads and synchronization techniques? If not, probably it's time to read on those topics. And I think you're going too far without knowing the basics.

I suppose that what is happening here is that you should be using a multi threaded application to do that... if your main thread gets blocked because you are processing the compilation... then the program won't answer to anything until it has finished...
You should read about a "worker thread" and the synchronization objects that are available.
Hope this helps...
PS: Are you sure that you have made a compiler?

If he knows how to program a compiler, he should have known how to do flow-control though.

By using GCC compiler i am compiling, linking and executing the 'C' source file.
My application selects a 'C' source file and by using GCC compiler i am compiling, linking and executing it.

I see. So you are not making a "compiler" per se which parse every token in the sources, but are making a GCC invoker.

Normally, when using the Spy++ find window tool, you can mouse over a dialog and the controls will highlight as you mouse over them, allowing you to click them and then have Spy++ select them in its list of windows.
We have a dialog app and this has worked fine for that app. We recently upgraded to a new version of a third party GUI library we use and are seeing some wierdness.
When trying to use Spy++ to examine the windows, I noticed that the Spy++ find window tool no longer works in this dialog. With the find window tool active, when you mouse over the dialog the controls do not highlight. If you move to the title bar the dialog does highlight. If you click the dialog, you can see it in the Spy++ list along with all the child controls.
I guess I'm grasping at straws a bit, but this seemed really unusual. I can run an older version (before the third party GUI library update) and it works fine.
Any ideas what (if anything) this strange Spy++ behavior could indicate?
