Which tells us nothing. What exactly is failing? Are you getting a compiler/linker error. Is an assertion firing? Have you stepped through the code to see exactly what is (not) happening?

Hi,
does anyone know a possibility to mark code (.exe .dll) as unpageable!
to prevent windows from paging these code out of the memory.
Tanks,

VirtualLock(), but if you have to ask then almost certainly you shouldn't be using it.

So does that mean that until a person learns how to use a function or an API, they shouldn't be using it? I'm curious how one goes about learning about something without first using it?

Not at all, you've over generalized. I said that about VirtualLock in particular not about API's in general.
Page locking memory is one of those things that is very seldom a good idea. The appropriate times for doing it usually occur in device drivers, and they use a different, kernel mode, API to accomplish this. Mostly people think they'll page lock parts of their application to 'improve performance' and that almost never works. Trust the memory manager to trim the working-set appropriately.
Off hand, the only legitimate reason I can think of for locking pages in a user-mode app is to prevent plaintext from being written to the pagefile in a crypto scenario, and I'm not positive it even guarentees that as expected.
Hence, unless you already know a _lot_ about how the Windows VM system works, you shouldn't be tampering with it, and if you don't know about VirtualLock then clearly you don't know enough about the VMM.

I am trying to call menu from dialog. That menu's ID is ID_MYMENU.
When you click on this button, it will do certain thing. what i
am trying to do is to call this ID_MYMENU from dialog and do the
same thing as when you click on the ID_MYMENU. I was thinking
to use function like SendMessage(ID_MYMENU,**,**) something like this.
Please help!

You don't need to call the menu from a button.
If you want more than 1 GUI object to be handled by the same code, then you should just edit the message maps to point to the same function.
|
|
|
|

If your dialog box is modal, it could be dangerous to activate a command of the application. Anyway, here's the syntax:
CMainFrame *pFrame = AfxGetApp()->m_pMainWnd;
pFrame->SendMessage(WM_COMMAND, ID_MYMENU);
Beware that with SendMessage, the call won't return before the execution of the command.

I am in the midst of making a FlexGrid editable in my dialog app.
For that I am creating a floating edit box same as dimesions of a cell and then placing the box at a specific cell.
What is the correlation between coordinates
Finally i need to place the edit control(say pEdit) at a cell location using
pEdit->SetWindowPos(0,x,y,width,height);
how do I calculate x , y width and height
I tried this
int y=m_flex1.GetCellTop();
int x=m_flex1.GetCellLeft();
int width=m_flex1.GetCellWidth();
int height=m_flex1.GetCellHeight();
But values seem goofy
I need to convert twips to pixels .
so I need
1. Conversion between twips and pixels
2. Final values of x ,y , width and height !
Please help

I started doing this as an experiment for one of my projects but then I aborted the idea. Download whatever stuff I wrote from this link [^] but let me warn you that I put it there for you and I will remove it as soon as you are done downloading it. I am running out of space, that's why. Let me know how it works for you.

the edit box is shown intially at cell 1,0, when I made this
long lCellTopTwips = m_Grid.GetCellTop();<br />
long lCellLeftTwips = m_Grid.GetCellLeft();<br />
long lCellWidthTwips = m_Grid.GetCellWidth();<br />
long lCellHeightTwips = m_Grid.GetCellHeight();<br />
<br />
long lCellTopPixels;<br />
long lCellLeftPixels;<br />
long lCellWidthPixels;<br />
long lCellHeightPixels;<br />
<br />
TwipsToPixels(lCellTopTwips,<br />
lCellLeftTwips,<br />
lCellTopPixels,<br />
lCellLeftPixels);<br />
<br />
TwipsToPixels(lCellWidthTwips,<br />
lCellHeightTwips,<br />
lCellWidthPixels,<br />
lCellHeightPixels);<br />
<br />
<br />
m_Grid.GetWindowRect(&rect);<br />
ScreenToClient(rect);<br />
pEdit->MoveWindow(rect.left + lCellLeftPixels,<br />
rect.top + lCellTopPixels,<br />
lCellWidthPixels,<br />
lCellHeightPixels);
a function called MoveOperation()
and on the OnClickEvent for the Grid I called this function . I find that the edit control is nt shown !!!

I'm not sure I understand exactly what you did. If I understand correctly, you call a function called MoveOperation() in onclickEvent and perform the required operations for the move.
That seems correct, however, there is something I didn't include in the original post because I thought it was obvious. Add this at the end of your MoveOperation():
pEdit->ShowWindow(SW_SHOW); //Show the edit box
pEdit->SetFocus(); //Set focus to the edit box
pEdit->SetSel(0,-1,FALSE); //Select the text in the edit box

I am trying to make a game that can 'think'. This is a tic-tack-toe game. I was wondering how to make it. The basic layout uses arrays. The only thing I need to do is to make the computer 'Think'. Please reply with anything it doesn't matter what. I would appreciate it if they helped. Thanks.

Do a google on Tic-Tac-Toe algorithms - there is a lot of data out there!
My solution relies on "brute-force" because the grid is only 3 x 3. So an if-then tree can be constructed to handle every possible condition in the game with little effort.
There are only 3 possible starting positions - a corner, a non-corner/non-center, and the center.
There are a max of 5 moves per player.
If you assign every space on the grid a number that is twice the number before it, you'll end up with:
1 2 4
8 16 32
64 128 256
There are only 16 different ways that an opponent can have 2 out of 3 squares - and those 16 ways can be expressed as the sums of those numbered squares.
You can test for a condition where the opponent can win on the next turn by comparing the sums of the opponents rows, columns and diagonals (and subtracting the value of the computer's squares) against those 16 values.
