First thank you for your quick response to my problem on "The Code Project".
What you say seems to me very logical, but I have also the case in a multithreaded application where SetForegroundWindow fails to give the focus to the good window. In fact it seems that no window has the focus until I click on a window.
Do you know a logical explanation about that or a place to find an explanation to this problem.

Perhaps in a larger program the size of a STL program becomes more the same as a program without STL, however, I'm am creating some example programs and have realized that the little 50 or so line example programs I'm writing are building up to 500k or more in debug and 100k or more in release.
I looked a little closer and saw that there are quite a few dependencies that must be the reason. Is there any way around this? Is this normal? Do you guys/gals find it not as big of a problem with larger programs as the templatized functions and containers make up for themselves?
Thanks for you input in advance,

Debug code is ALWAYS really bug, don't worry about it.
In release mode, check your compiler optimisations. Default is optimise for execution speed, you can do a lot to bring the size down.
But the single biggest thing that affects your average windows program (maybe not STL though), is whether you statically link with MFC or dynamically link. dynamic linking is smaller, but your program has more dependancies.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

I'm trying to get my program to send text to the edit box of another window.
I have no probelm getting the window's handle, and according to my "if" statements, its working.
this is what I have set up for my code while winvar is the variable for the window im sending text to:
::SendMessage(winvar, WM_SETTEXT, 0, (LPARAM)_T("text"));
Nothing appears in the windows edit box when I run the function, and it should be working according to my if statements.
|

|

When you do that, does it send the text to the title bar, or into the edit box?
I just tried the exact same code as you, and it changed the "Calculator" on the calculator window to "Hello World".
What I am trying to do is send text to the edit box... I'm not sure if that is the right name for it, so I'm going to say that i want to send text to the box that displays the numbers in the calculator window.

Try this then :- [it makes the title of calc "hello world" and the text box "chk" 
void CTest_deleteDlg::OnButton1()
{
HWND hWnd;
::SendMessage(hWnd=::FindWindow(NULL,"Calculator"),
WM_SETTEXT,0,(LPARAM)"Hello World");
::EnumChildWindows(hWnd,EnumChildProc,0);
}
BOOL CALLBACK EnumChildProc( HWND hwnd,LPARAM lParam )
{
::SendMessage(hwnd,WM_SETTEXT,0,(LPARAM)"Chk");
return false;
}

CHttpFile *s;
CHttpConnection *c;
CInternetSession *is;
if (useProxy)
is = new CInternetSession(NULL, 1, INTERNET_OPEN_TYPE_PROXY, ProxyURL);
else
is = new CInternetSession(NULL, 1, INTERNET_OPEN_TYPE_DIRECT);
c = is->GetHttpConnection("ip", (INTERNET_PORT) 4000);
wsprintf (param,"nickname=%s&password=%s&entranceRoom=%s",User,PassWd,RaumName);
wsprintf (length,"Content-Length: %d\r\n",strlen(param));
strcpy (header,hdrs2);
strcat (header,hdrs3);
strcat (header,hdrs4);
strcat (header,length);
strcat (header,hdrs5);
wsprintf(rline, "/Login.html");
s = c->OpenRequest("POST",rline,referer,0,NULL,"HTTP/1.1",INTERNET_FLAG_DONT_CACHE | INTERNET_FLAG_RELOAD);
LPCTSTR lpszHeaders = header;
s->SendRequest(lpszHeaders, strlen(header), param, strlen(param));
f = new fstream("back.html", ios::out);
while (s->ReadString(l) != FALSE)
{
... // some *f things
}
delete f;
s->Close();
delete s;
delete c;
delete is;
this is only a little example from my code ... not even perfect but its working.
u always have to check ur headers and the things that you send.
best way to check is a html browser and a packet sniffer. there are many outta there. with the sniffer u see the original header and data. and could also check your program that it send also the right one.
bye

Consider the following 2 program code segments. Which one utilizes main memory more efficiently, and which one takes up more space in main memory for variables?
Code segment #1:
int score1, score2, score3;
.
.
Code segment #2:
int score[3];
.
.

no difference in space. they will probably be allocated identically, too (three consecutive DWORDs)
