you could have your software have a timed execution length, only be able to run for 60 minutes at a time, and completly disabled the save/export/render/... or have it generate a watermark on the saved data ).

This is not really what I need. I know there are some programs wich can be evaluated lets say 30 days without buying a licence. I need to impelement something similar.
Any suggestions?
|

When your program is installed, write a value, with a very obscure name, to the registry that represents the date of installation or the date it will stop working, in a not-so-obvious format. Each time the program is started, check this value. Once the 30 days has elapsed, remove the value from the registry. Most folks don't try and figure out why/how the evaluation period has ended until after the fact. That's why, instead of keeping the value in the registry, it is removed altogther. This method works fairly well. Of course, a very determined person could thwart this. Good luck.

Is there any way to create a simple client/server program in a 16 bit (dos)
project?
I can only use this kind of mode (dos 16 bit) because the microchip i am trying to control remotely connected to the server only supports borland 5.02 DOS 16 BIT projects.
thank you for helping and any suggestions are heart-warmingly welcome!

Hi together,
i have got a SDI porject with some Dialogs inside. One main Dialog, should set some global Flags so that other Dialogs can read it.
I have tryed at first the way i would do it in a C++.
<br />
Class{ privat: <br />
static int m_Flag <br />
Plublic: get....<br />
set..
but this can not work inside the Cpp. ?? Ok so i tryed in a direction of extern int m_Flag; i found some examples in the net. But not woring with me.
So next try is usage of Messags. But i never usesd them before so most attractive for me seems to be the Extern definition??
But maybe i am too  and this the reason why its not working.
Can somebody pleaseee give me tip or an example

you could pass a pointer to the main class to each dialog.
in the main class, either make the variable public ( bad idea ) or have Get/Set methods for each of the values ( better idea ).
and don't forget to #include the main class header in each dialog.

And how do you want check float by one symbol ?

I'm not sure exactly what you are asking, so I'll hypothesize and suggest functions like isdigit(), isalpha() and iswhite(). If I'm way off the mark, please rephrase what it is you are trying to do.

How would I go about retrieving the default dialog background color?
|
|
|
|
|
Use GetPixel(...) function to get RGB value of Dialog box

See GetSysColor(). On non-XP and non-themed XP systems I think you can use COLOR_3DFACE.

Hi
Could anyone please point to me a good tutorial and source code for C++ implementation for adaptive arithmetic encoding.
I have gone through Nelsons tutorial and few others. The implementation is bit difficult for me to understand.
Thanks in advance

Does anyone know where to find the solution to the exercise presented in the book, besides the companion book C++ Solutions.

I'm trying to use CBitmap to manipulate a bitmap, but there's no easy way for me to extract a color from a bitmap (like GetPixel(x, y) in CWnd-derived classes). Is there something I'm missing? Suggestions are well appreciated. Alternatively, is there a way to fill a bitmap with one color like FillRect() does with DCs?
thanks,
augy
