Why not use sprintf? Like so:
Greetz,
Illco
char pBuffer[512];sprintf( pBuffer, "Caption %d", variable );-- use it in title callGreetz,

Best way would be to change the window caption every frame. You can do that by:
or, to make sure the C++ guys dont bite my head off...
float variable = 3.1415fchar buffer[256];sprintf(buffer, "state is now: %f", &variable);SetWindowText(hWnd, buffer);or, to make sure the C++ guys dont bite my head off...
float variable = 3.1415fstd::string title;title << "state is now: " << variable;SetWindowText(hWnd, title.c_str());

sprintf(buf,"The state is %d", number);
if (!CreateGLWindow(buf ,640,480,16,fullscreen));
if (!CreateGLWindow(buf ,640,480,16,fullscreen));

thank you for the fast replys
however
@PlayfulPuppy: writes 0.00000 nomather value
the cpp snippet std::string title; error string not member of std
@traiger: invalid constant char* to int
further: the sugestion would not be a concat to the orr. caption in the gl window
eg
if (!CreateGLWindow("NeHe's Tutorial -state is now: " #+ variable-in-here-#
,640,480,16,fullscreen));
the sentence/String 'state is now' is ..simply added the program variable should then be string converted and as a string concatenated to the title String
-in- the gl window
perhaps not so simple after all..

1) Whoops, that should probably be:
sprintf(buffer, "state is now: %f", variable);.. I think. I haven't used sprintf in quite a while now.
2) Dont forget to add
#include <string>Also, dont forget that if the variable changes and you want the window title to reflect this, you'll have to set the caption again with SetWindowCaption.

Nah, it's simple. Just a couple of minor errors is all.

make sure buf is an array of char of adequate length.
but it is sprintf you need to use.

A C++ ostringstream will perform the same thing as sprintf, but without the concern of experiencing a buffer overflow.
#define DEFAULT_WINDOW_TITLE "My Application"#include <sstream>using std::ostringstream;#include <ios>using std::boolalpha;...ostringstream title;// remove the call to boolalpha to format the bool as 1 or 0 instead of "true" or "false"title << DEFAULT_WINDOW_TITLE << " state is now: " << boolalpha << boolean_var;if(!CreateGLWindow(title.str().c_str(), 640, 480, 16, fullscreen)){ ...}...April 07, 2005 09:02 AM
..almost there
-but
Why is a boolean var ignored?
i can use a float and it is shown....?
..btw for those who want to know
i used the edited codesnip from PlayfulPuppy and inserted it in the
int DrawGLScene(GLvoid) -method
(because the draw-opps is updated every tick)
ofcause the buffer needs to be outside.. :) as does the initialization of the var
eg:
where fi is my 'boolean' for the state un the appl.
only that 'bool' needs to be a ....float
so not %f what then ...%b .. no ;)
