I think it's too small sizes.
If there is place to read about technology of making own bmps?

I would to add two methods to already existing activex control. How to do go about it. Should I add a new interface. If yes, how to do it. Any article or help.
Best Regards

Do you have the source code of this ActiveX ? If no, then it is impossible to do. An ActiveX is a specialized dll which is executable code. So, you cannot add code to such a module, you need to start from the source code, then add your specific code and recompile it.

No, you can do this if you actually add the control to your control. Then you'll have to have functions in your control that call all of the embedded control's functions, plus adding the two new methods you want.

Hi
I found that char could be converted to an interger as follows:
char c = 250;
int a = int(c)
How can I get the a value of a to be the same as what I put in? It sometimes comes out negative, although I can add 256. There is a simpler way?
thank you

unsigned char c = 250;
Signed char limit is 127.

Make c an unsigned char. (Yes, there are such a thing as signed and unsigned chars in C).
Or cast c to an unsigned char. So:
1.
unsigned char c = 250;
Or:
2.
int a = (int) (unsigned char) c;
Or both...

OR:
int a = 250;

|
|
do you want the value of a to be 250 in this case?

Thankyou ... converted to an unsigned char and it works great

Yah i misunderstood. They are right.

union
{
char c[sizeof (int)];
int n;
} Convert;
char c = 250;
Convert.n = 0;
Convert.c[0] = c;
Then, in Convert.n you will get the proper value.
Good luck!

A cast is actually not necessary. You could accomplish the same with:
int a = c; because a char gets internally promoted to an int during such operations.
A char can hold values in the range -128 to 127, whereas an unsigned char can hold values in the range 0 to 255.

Hi there.
As the other replies have stated, you need to use the unsigned char for values above 127. To perform explicit conversions in C++, you should use the static_cast instead of the old C-Style casts.
<br />
unsigned char c = 250;<br />
int a = static_cast<int>(c);<br />
Cheers

For integral types, this is not necessary.
