DOS 16 bit client /server (C++)(maybe winsock)

ola...
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!

I want to pass int values between Cpp s

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 Dead | X|

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.

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.

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

getting colors in bitmaps...

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

Hey,
Try this.
CDC *pDC = this->GetDC();
CDC mDC;
mDC.CreateCompatibleDC(pDC);
mDC.LoadBitmap(IDB_BITMAP1);
Now you can used GetPixel() to extract color of bitmap.
mDC.GetPixel(...);
this->ReleaseDC(pDC);

Hope this will work.

To work with a bitmap, you need to select it into a DC. The other way is to use a DIBSEction, then you can access the bits directly. Get/SetPixel are incredibly slow.

vc++ string Find problem

hi all

I got the text from the popupmenu item using GetMenuString like so:

TCHAR itemText[MAX_PATH] = {0};
GetMenuString(m_hList,i,itemText,MAX_PATH,MF_BYPOSITION);

then i try to find if certain sequence is in the itemText like so:

TCHAR strTOSearch[2]="(";

if(_tcsstr(itemText,strToSearch)!=NULL)
{
....
}

now if the strToSearch does not contain any white space, it works fine, but then strToSearch[4]="h h";

then it won't find the string even though itemText does contain "h h",

what am I missing?

thx

I did not used TCHAR yet. I did a simple test with strstr() and it worked.

<br />
char tst[50];<br />
strcpy(tst,"Hello you!\nThis works!"); // put a string into tst<br />
if (strstr(tst,"lo y")) // strstr returns NULL if there is no ocurance<br />
	m_output="OK";<br />
<br />
UpdateData(FALSE);<br />

The str-functions are pretty old and are not very object orientated but they don't let you down. I like them. Wink | ;)
