I used two monitors back when I was developing for Windows 3.x. One was color and the other was monochrome. Since each was located at a different memory address, it was easy to write to both. The GUI stuff went to the color monitor and the debug stuff went to the monochrome monitor. I got really used to it and sorely missed it once Windows 9x came out.

You're saying it can't be done right now that way. In either case I believe I have a solution. I configured my 2 monitors in Windows and I create a CFrameWnd derived object using Create(...) and I pass the location and size to this function such that the window is created past the first screen size, and Windows automatically creates this on the second monitor. Now I have this frame that I cran draw stuff in. However I'm still having trouble making the frame truly full screen. Any help? I've tried the ChangeDisplaySettings() function however that changes the first monitor to full screen and not the second one. Any help?

WMDM and the value of g_wszWMDMFormatCode

No, I was just reflecting on the past. I've not ever used Windows with the new dual-monitor feature. When I saw it being used, the guy spent way too much time moving his head back and forth between the two. I didn't see the point.

I also find myself loosing the mouse cursor into the other screen too many times. I'm used to the clipping and usually don't worry about horizontal motion when trying to reach the X button to close =).

Anyway I think I have it under control.

Could someone who has the Windows Media Device Manager 10 SDK installed please tell me what the value of g_wszWMDMFormatCode in mswmdm.h is?

I suspect it is L"Format Code" but if I use that, it doesn't appear to be working.

Yes, I know.. I could just install the SDK, but our license is currently being processed (so I don't have the SDK yet) and I need to do a quick test.

Thanks in advance.

OnClik and OnDoubleClick event

I am handling OnClik and OnDoubleClick event on a listControl. When ever user doubleclicks on a item, first onclick and then OnDoubleClick event gets fired. Is there a way to avoid onclick event when user has DoubleClicked on the item ?

How about starting a timer that's longer than the interval between double-clicks? So if 200 ms is the longest interval between double-clicks, start a timer with an interval of 250ms. In double-click event and in timer event, kill the timer.

I'm curious: what does your OnClick() handler do (eg: does it update a selection count?)

OnClick refreshes the selected item on the listViewControl.
DoubleClick refreshes and then allows the user to modify it. The refreshing happens twice in this case.

problems with writing to files

24-Sep-04 9:24

From look at Spy++, when a list control single-clicked, it receives a WM_LBUTTONDOWN message followed by a WM_LBUTTONUP message. When a list control double-clicked, it receives those two messages followed by a WM_LBUTTONDBLCLK and WM_LBUTTONUP. Can you monitor for WM_LBUTTONDOWN and WM_LBUTTONDBLCLK separately?

I have started writing a game in C++ and while creating the login section of it I have come to a problem. I have it to where it gets the string and types it on the next line. But when it sends it to the save file it only shows up as little box symbols. I had it working before but i changed some things. then i changed them back and now it doesn't work. i can't find anything i forgot to take out or change.

here is my code:

#include "stdio.h"
#include "conio.h"
#include "stdlib.h"
#include "time.h"

char username[12];
int i, ch;
FILE *MyHandle;
char MyFile[12] = "Save.txt";

void main(void)
{
printf("Welcome.\n\n\n");
getch();
printf("Please identify yourself.\n");
printf("Name: ");

for( i = 0; (i < 12) && ((ch = getchar()) != EOF)
&& (ch != '\n'); i++ )

username[i] = (char)ch;

username[i] = '\0';

MyHandle = fopen( MyFile, "a+");
fprintf( MyHandle, "%s%c", username);
fclose( MyHandle);

printf("Welcome ");
printf( "%s", username);
printf( ". Go to the waiting room and await your orders.");
getch();

}

You are allowing up to 12 characters to be input for the name so username needs to hold 12 plus 1 for the '\0' character.

An additional byte is being popped from the stack with this. Either remove the %c, or add another parameter.
