Well, all Im running is the message pump. (PeekMessage then TranslateMessage & DispatchMessage). Is there a safe way to stop the message pump ?

PeekMessage Does not block if the message queue is empty, use GetMessage instead.

Are you using GetMessage you in your message loop or PeekMessage?
Do you have more than one thread?

ok... hi all 
ive bean kindof relient on Kilowatt. "sorry kilowatt"
now my question...
i want to random a number betwean 1-10.
i looked up rand()... automatically i thought that you could just put the number that you want to be randomized in the ().... like for example
rand(10)... that didnt work.
there is srand also...
why wont the rand(10) work... and, how do i work rand()?
Thanks all!

Do a rand()%10 to generate a number between 0 and 9

Yes it will, because you havent srand'd first :-
srand((unsigned)time(null));

ok...
give me an example from head to toe, about required headers... srand, RAND_MAX, and rand().
because ive tried everything, and its still doesnt work.
~SilverShalkin
ps... #include <cstdlib> i think thats the header
|
|
|
|

#include "stdafx.h"
#include <stdlib.h>
#include <time.h>
int _tmain(int argc, _TCHAR* argv[])
{
srand((unsigned)time(NULL));
for(int i=0;i<10;i++)
printf("%d\n",rand()%10);
return 0;
}
My output :-

Is it possible for an Executable to export functions just like a dll? I added a .def file to my project, it compiler good and using the dependency walker i saw it was exporting the functions, but when i use them from outside it crashes/does nothing. Is it possible?
Thanks

I think to do that, you'd have to write an EXE COM server.

p.s. pardon my crude terminology, but my COM aint great, not yet

Yes, and sometimes .exe's do just that when people define the wrong macros or include the wrong header files that are intended to only be defined when creating a function exporting library.

There you go, you have exported the symbols!
but when i use them from outside it crashes/does nothing.
So long as you obey all the rules obeyed by a DLL that has no initialization code whatsoever, and you LoadLibrary yourself it will work just fine. A PE is a PE is a PE... (Portable Executable).
May I suggest you read up a bit on how PE, DLL's, compiler runtimes in general and such actually works before even trying to do something like this? I've got around seven years of heavy Win32 development under my belt, and I've never encountered a situation like yours (that wasn't a design error).

Here's my code:
ifstream MyFile( "somefile.txt" );
MyFile.ignore( someNumber , '\n' );
What I want to do is have the someNumber be infinity, or just have the program ignore until the program reaches a '\n' character. Should I just make someNumber a really, really big number or is there a way to say, ignore until you find a '\n' characer.

Won't reading in an entire line do that for you ?

Since ignore() takes only an integer (not a size_t) you can only skip 2^31 (around 2 giga-) chars. If you want something closer to infinity you'd probably have to use OS dependent integral types.
If you accept 2GB as the limit for the first newline character, you could use INT_MAX from <climits>.

Hi, Is there a way to have a dialog based application consisting of several pages? For example, I am trying to create a credit card application: In the first Dialog box you would input your personal info. How do I go about having a "Next" button that will send me to the next page or dialog box where I would input my "employment info" and so on.
Thank you very much
ps. I am a beginner

Yes, that's easily done using a "wizard" interface, similar to an installer dialog. You'd need to use a CPropertySheet as your main dialog. Each page would be a CPropertyPage. You'll need to call SetWizardMode() (I think that's what it's called) on the property sheet to enable it's wizard mode.

Property sheets in wizard mode will be just what you want.

yes. create your dialog app, then change the CDialog to a CPropertySheet and add as many pages as you need. you'll also probably want to make this a "wizard" type of property sheet.
unfortunately, it's not a small topic, so i can't lay it all out for you. it's not really difficult, but some parts are tricky the first time you see them.
-c
<font size=-2>
main(){float _,l,O,I,o,x;char i;for(x=-1;x<1;x+=.05,putchar(10))
for(o=-2;o<.9;o+=.05,putchar(i?'?':':'),_=l=O=I=--(i=1))for
(;((O=_*_)+(I=l*l)<4)&++i;l=_*l*2+x,_=O-I+o);}
</font>

//I want to dynamically create a new combo box just to the right of an existing combo box. The problem is I do not seem to be able to set the size of the dynamically created combo box. Any suggestions???
CComboBox* pExistingCombo = (CComboBox*)GetDlgItem(IDC_COMBO1);
//The new control should have the same stlye as the existing control
DWORD dwStyle = ::GetWindowLong(pExistingCombo->m_hWnd, GWL_STYLE);
//Get the edit area and drop area of the old control so they can be the same
//size in the new control
CRect rEditArea, rDropDownArea;
pExistingCombo->GetWindowRect(rEditArea);
ScreenToClient(rEditArea);
pExistingCombo->ShowDropDown();
//get the size of the drop area
pExistingCombo->GetDroppedControlRect(rDropDownArea);
pExistingCombo->ShowDropDown(FALSE);
ScreenToClient(rDropDownArea);
//Move the new control over to the right a little
rEditArea.right += 150;
rEditArea.left += 150;
//Build the new combo control
m_pComboNew = new CComboBox;
m_pComboNew->Create(dwStyle, rEditArea, this, 1222);
m_pComboNew->AddString("one");
m_pComboNew->AddString("two");
m_pComboNew->AddString("three");
//Question??? - How do I set the drop down size of new combo to be same as existing combo?
m_pComboNew->ShowDropDown();
 Thanks

Before creation, add this line:
rEditArea.bottom += rDropDownArea.Height(); The non-dropped height of the combo box is always determined by the size of its assigned font; sizing it vertically determines the dropdown height.
