Probably he wants to show the popup menu on click of the button Smile | :)

A button doesn't expand. it is clickable, and eventually can be shown as a checkbox/radio.

But Why are you down voted for this?? Confused | :confused:

probably, and I thought of that too, but God, what if the OP doesn't specify it clearly ?
are we supposed to read in mind ?
So is my answer worth a 1 ?! Confused | :confused:

My guess would be that the OP wants to display the "Import Traffic matrix" text initially on the button. When the user clicks on the button he wants to display "View and Export Traffic matrix" on the same button, which obviously won't fit the initial size(something he sets depending on "Import Traffic matrix" at design time) $Shucks | :-\$

Somethings seem HARD to do, until we know how to do them.

that doesn't prevent you from writing a well written question explaining exactly what you want so we can understand your point and help you this way...

Use MoveWindow to set the size of the button once the user has clicked on it and change the text. You need to check width so that the text fits in

m_btn.MoveWindow(10,10,300,40);

I have a question as to when a preprocessor/macro constant should be used, and when a constant variable should be used.

Or it would be better if i put it in this way,
In a program,
when ONLY a macro constant MUST be used and not a constant variable?
when ONLY a constant variable MUST be used and not any macro constant?

Usually a constant variable is preferred (because it is typed).

When using macros you should always remember that they're a direct text substitution, not something the compiler does. Imagine that before your source file is passed to the compiler a normal text manipulation program substitutes the macros with their values and this changed text of your source file is sent to the compiler.

One case when macros might be better than constants is when declaring arrays.

#define MAX_PATH 260
char arr[MAX_PATH];

always works, but

const int MAX_PATH=260;
char arr[MAX_PATH];

might give you problems on older compilers.

There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

There is no rule when to use constants or when to use preprocessors..
It is always better to use constants because it is typed.

Easy as p**s, simply reverse the operation you used when you changed it from Unicode to non-unicode build.

Here, the change you speak of here.

FFS! Look it up, it's hardly rocket-science.
