Thank you All
I have have got the Solution. I did not initialize the object of class.

Without looking at any code it's kinda hard to say. But to hazard a guess, I would say the NCHITTEST message is being handled incorrectly and that the rectangles of the buttons are improperly positioned.

what do you exactly want us to do here?
you have pasted your whole code here
no description?
no comments of the code?
no proper indentation?
and that too incomplete code.
where exactly your problem is?
please put some write up before your code
and keep the code as simple as possible.
and before posting, read the post "How to get an answer to your question" by chris maunder above your post.

this guy is acting like a troll... but strangely, he is not, because it happened to him to answer to some questions we've been asking to him.
but anyway, this guy deserves once again to be flammed for this post

donot get discouraged.
just repost your query with some better clarity.
gud luck.

after Waleed has asked his question, related to intellisense, i have got one more question on that topic.
iam using vc++ 6.0.
in my code editor,
say if i use a variable for example,
CString str;
and if i type "str" and then ".", the functions/members of the CString class are supposed to pop up.
but sometimes, this is working and sometimes not.
any ideas like, how and where to enable it if possible.
gud luck to Waleed for his post and hope for the solution.

You could try deleting the .ncb file (which is the intellisense database). This works for me most of the time .. good luck and thanks for your nice words...

Hello,
I'm using __declspec(property) to access get/set methods as properties (like in C# and VB.NET). Now, the problem is that both the property name and the get/set methods show in the intellisense list. Is there anyway to remove the names of the get/set methods from the intellisense list?
Here's an example, I have two methods, one is a get method with the name getText and another set method with the name setText, the name of the property is Text. I only want Text to show in the intellisense list, I don't want either getText or setText to show up in the list.
Thanks for any suggestions...

did you face this problem in COMponent?
if so, then i have some more questions, before arriving to the solution.
see you tomorrow morning.

No, I'm just trying to use properties in a normal c++ class

Hello all,
In a project I am currently working on, I would like to have some functions (like for example the logging) running as a server that can be addressed by all modules that may simultaneously be running. Does anyone have a link to articles or examples of how to build such server software and how to interact with it from the other modules?
Thanks in advance,
William

hey there!
I have a problem dealing with this bitmap. using MFC, i must create a function that return the values of bitmap frequency vs. its pixel value when I load it in the window. This is somewhat like a histogram.
Can somebody share me some hints or ideas about this?
Thanks!

Would you care to explain a little more about what exactly you are trying to do? What is "bitmap frequency" and "pixel value", how do you intend to calculate these values and how are you going to represent your found data?

You loop over the pixel and make a map<int, int=""> with the color_number as key and the number of pixel with this color_number as value.
typedef std::map<int, int> HistoMapT;
HistoMapT theMap; For every color-number you encounter, you add one to the value under the key "color-number"
E.g. The first pixel has value 30:
You check if this number is already in the map. When it is, you increment its value. When its not, you insert it with a value of 1:
HistoMapT::iterator theIterator = theMap.find(color_number);
int value = 1;
if (theIterator != theMap.end() ) {
value += theIterator.second;
}
theMap.insert(MAKEPAIR(color_number, value));
You see, std::map is quite helpful here, providing you with elegant and easy to read code.

maybe, but it will be very very slow, compared to:
int * histogram = new int[256 * 256 * 256];
memset(histogram, 0, 256 * 256 * 256 * sizeof(int));
for (int x=0;x< w;x++)
for (int y=0;y< h;y++)
{
histogram[(int)RGB(pixel.Red, pixel.Green, pixel.Blue)]++;
pixel++;
}

May or may not. That probably depends on the pattern of usage and the picture.
You are newing 28MB in one piece here.
AND you are still limited to 8-bit per color.
