Hi !
Well, one way to solve the document problem that you have is to pass in the DoModal of the Dialog as a parameter your Document ( then you can play with the data inside your dialog having that pointer to the document), just override DoModal in your dialog ( you have to declare that virtual).
Modal dialogs are easier to use ( for the programmer and for the users) than modeless, so maybe better to use modal dialogs whenever is possible and modeless only when is needed.
A good place to look for answers is: http://www.deja.com

If what you're after is having commited pages with increasing contiguous addresses without imposing an a priori limit, you can always reserve the largest block of memory the system allows you to (which is 2GB minus some safeguard amount of memory for the rest of the program and libraries, say 1.8GB). After all, reserving such a huge block of memory costs nothing --the system is only doing some bookkeeping of your request.
It's better to reserve this block of memory as soon as you can, so that the memory hasn't been fragmented by then.
If you run out of memory after consuming the 1.8GB, then there's nothing more you can do: a process cannot simply handle more memory than that.

Hi
I hope this question is an easy one for all you experts here at CodeProjetct 
I have a dialog based app that launches another modeless dialog in OnInitDialog using Create and ShowWinow. So far everything works.
I declared a new struct using
struct CONFIG
{
CString one, two, three, andsoon;
}
The main dialog has a member variable named
CONFIG cfg
Now my question:
My second dialog needs to have access to this variable in order to read some values out of it
How do I set it up in order to be able to read values from CONFIG cfg from my second, modeless dialog?
regards
Gregor

Hi Gregor,
If you created the modeless dialog from the main dialog with something like Create(ID_MODELESS_DLG,this) (where this refers to the main dialog) then the modeless dlg has the main one as its parent, and the sentence
((CYourDlg *)GetParent())->cfg access the variable cfg. Note the casting to CYourDlg * (or whatever your main dialog class is called).

i used this article http://www.codeproject.com/com/vb_from_vc.asp to call a function from a vb dll but if i created a function with multi params then for some reason my string gets lost!!
I have used this in visual basic:
Sub irc_1_client_init(ByVal what_nick_name As String, ByVal what_server As String, ByVal what_channel As String)
blah
end sub
--------------------------------------------------------------------------------
and in c++ i call the function like this :
irc_clientClass->irc_1_client_init(_bstr_t("blah"), _bstr_t("east.gamesnet.net"), _bstr_t("#blah"));
but when the event triggers it dont send the strings to the dll for some reason the strings get lost!

There is an article here:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q145616
which explains how to activate the cut, copy, paste commands of Edit. The second step says:
Add an UPDATE_COMMAND_UI handler for ID_EDIT_COPY & ID_EDIT_CUT:
What exactly does that mean? If I add a public member function
public:
void OnUpdateNeedSel(CCmdUI* pCmdUI);
The program seems to work okay. I just don't understand what UPDATE_COMMAND_UI means. Do I need to add something to BEGIN_MESSAGE_MAP????
Please, please, any response any one can give me will be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

Those UPDATE_COMMAND_UI handlers are called by the framework to determine whether the handled command (ID_EDIT_COPY, etc.) should be enabled or disabled on your menu. If you don't provide those, my guess is that the commands "Copy" and "Cut" will remain enabled all the time, even when there's nothing to copy (nor cut).
Do I need to add something to BEGIN_MESSAGE_MAP????
Yes you do. Check the online help about ON_UPDATE_COMMAND_UI for more info on how to add such handlers.

How and where do I cahnge an icon in an SDI app? And am I limited it 16 bit colors?

Mike Dunn's C++ FAQ teaches you how to do it.
As for the number of colors, I think you are not limited to 16 (just try to know).

I'm designing a 3D graphics software, using OpenGL on a visual C++ compiler for all the graphics stuff. But as far as the non graphics stuff goes, I'm probably just going to use MFC. How do I use them together. For example, I just created a window and did all the animation stuff using OpenGL. How do I know use MFC to put little menus and buttons on the screen to do stuff. Or should I just use OpenGL for all that stuff?

I've got a little app I'm writing, and I went dialog based because I like the "toolbox" and "view window" (the view isn't an MFC view, just a control that behaves like one). Basically I want to have a view take up two thirds of the mainframe and one third with buttons etc stuck on it. Any suggestions?

Hey'all, i need something that'll block the keyboard and mouse so the user cant do anything anymore (or f*** things up like Bill would say it :p) but so you can still use SendInput and control the mouse and keyboard input programatically. Does anyone know a way to do this?
Thanks in advance.

Put a hook on keyboard and mouse messages, and throw them away.

Okay, it isnt done yet and this is the first time I have ever used arrays. Visual Studio 6.0 gave me 21 errors, and I dont know how to fix it.
heres the code:
// Password Generator.cpp : Randomly generates an 8 charactor password.
//with swapping vowls and consenents for maximum pronounciblity.
#include "stdafx.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
char cons[19];
char vowl[6];
int number[10];
cons[0]="b" || "B";
cons[1]="c" || "C";
cons[2]="d" || "D";
cons[3]="f" || "F";
cons[4]="g" || "G";
cons[5]="h" || "H";
cons[6]="j" || "J";
cons[7]="k" || "K";
cons[8]="l" || "L";
cons[9]="m" || "M";
cons[10]="n" || "N";
cons[11]="p" || "P";
cons[12]="r" || "R";
cons[13]="s" || "S";
cons[14]="t" || "T";
cons[15]="v" || "V";
cons[16]="w" || "W";
cons[17]="x" || "X";
cons[18]="z" || "Z";
vowl[0]="a" || "A";
vowl[1]="e" || "E";
vowl[2]="i" || "I";
vowl[3]="o" || "O";
vowl[4]="u" || "U";
vowl[5]="y" || "Y";
int number[0]="1";
int number[1]="2";
int number[2]="3";
int number[3]="4";
int number[4]="5";
int number[5]="6";
int number[6]="7";
int number[7]="8";
int number[8]="9";
int number[9]="0";
return 0;
}

First, cons is declared as an array of 19 characters. You are attempting set each item to a string logically or-ed with another string. The or-ed strings will result logically in a just a one. You probably want to set them to single character value so use the single quotes around each one. This applies to vowl also.
Second, number is already declared as an array of 10 integers. You have an int in front of each use of them. Also, you probably don't want to set each entry in the int array to a string. To set each one to an integer value you need to lose the double quotes.

If you're new to arrays, I assume you're relatively new to programming. In which case, you should be creating console apps, not Win apps. Replace the WinMain() function with a standard C-style main(). Also, you should use the "Console application" in App Wizard.

okay, what does this mean?
error C2440: '=' : cannot convert from 'char [2]' to 'char'
I got 25 of these for that code.

"b" is a character string of length 2. If you want just the character 'b', then use single quotes.

I have what may be a simple question. I have a couple of DOS apps that I would like to have a Windows Front-End for. I know how to launch the apps from the windows app, but I want the output to be piped directly into text box (or something like that), instead of sending it to a text file then reading the text file one line at a time. Is there a simple way to capute or redirect the screen output to a window?
Thanks,

This bit sends cout to a console
<br />
if( !AllocConsole() )<br />
MessageBox(_T("AllocConsole failed."));<br />
<br />
m_hConsole = GetStdHandle(STD_OUTPUT_HANDLE);<br />
freopen("CONOUT$", "wt", stdout);<br />
cout = new stdiobuf(stdout);<br />
