Window Size and position in registry

[electronicman_x]

2 questions: Q1: I'm currently working on an MDI program with controlbars and the Stingray Toolkit. I want to save the program's last size and position in the registry when the program is closed. Currently i'm able to store the controlbars locations into the registry using the SaveBarState function. I basically need to create my own registry key or find some similar function that will store the program's size and position like the SaveBarState function. I'm not really sure how to go about doing this. I can get the information about the program, but i dont know how to store it to the registry properly. Q2: The reason I'm doing this is because i want to save the appearance of the program so when it runs again it looks just as it was when it was closed. I also want to be able to size the program according to the screen real-estate on the desktop (the first time it runs or if the resolution changes). The reason for this is i have a few systems im running this program on that use multiple monitors and i dont want the window stretched across them. I also want to have control over the window size and position when it runs. I have some rough code, but i dont know if i should do things this way. some crappy code im playing with: (This lets me control the size but im not sure how safe this method is) //(inside MyApp()) CRect rClientSpace; CRect rc2; CWnd * pWndMain; pWndMain=(CWnd *)pMainFrame; pWndMain->GetWindowRect(rc2); SystemParametersInfo(SPI_GETWORKAREA,0,&rClientSpace,0); //checks horiz. and vert. to make sure it can make this window. if ( ((rc2.left+1000) < rClientSpace.right)&&((rc2.top+750) < rClientSpace.bottom) ) { pWndMain->SetWindowPos(NULL, rc2.left, rc2.top, 1000, 750,SWP_NOZORDER);//I want 1000x750 when feasible } pWndMain->GetWindowRect(rc2);//to see the results in debugger Any ideas or code would be great.

This is how I do it:

void CMainFrame::OnDestroy()
{
WINDOWPLACEMENT wndPlace;
if ( GetWindowPlacement( &wndPlace ) )
{
AfxGetApp()->WriteProfileInt( "WndPos", "Left", wndPlace.rcNormalPosition.left );
AfxGetApp()->WriteProfileInt( "WndPos", "Top", wndPlace.rcNormalPosition.top );
AfxGetApp()->WriteProfileInt( "WndPos", "Right", wndPlace.rcNormalPosition.right );
AfxGetApp()->WriteProfileInt( "WndPos", "Bottom", wndPlace.rcNormalPosition.bottom );
AfxGetApp()->WriteProfileInt( "WndPos", "Max", wndPlace.showCmd == SW_SHOWMAXIMIZED );
}

CFrameWnd::OnDestroy();

}

void CMainFrame::ActivateFrame(int nCmdShow)
{
CRect r;

r.top = AfxGetApp()->GetProfileInt( "WndPos", "Top", 0 );
r.left = AfxGetApp()->GetProfileInt( "WndPos", "Left", 0 );
r.bottom = AfxGetApp()->GetProfileInt( "WndPos", "Bottom", 400 );
r.right = AfxGetApp()->GetProfileInt( "WndPos", "Right", 600 );
MoveWindow( r );

if ( AfxGetApp()->GetProfileInt( "WndPos", "Max", -1 ) == -1 )
{
	CenterWindow();
	nCmdShow = SW\_MAXIMIZE;
}

if ( AfxGetApp()->GetProfileInt( "WndPos", "Max", 0 ) == 1 )
	nCmdShow = SW\_MAXIMIZE;

CFrameWnd::ActivateFrame(nCmdShow);

}

Jeff, What version of StingRay are you using. OT-Pro includes SECWorkspaceManagerEx() which saves the size/pos/state of all windows/toolbars etc. I use this in ED (see sig). Also nore that SPI_GETWORKAREA is only for the primary monitor. If you want to force users only to use that, you are ok, but most users won't like that. Instead use code like: #include <multimon.h> if ( WinPlatform() & ( WIN_98 | WIN_NT5 ) && GetSystemMetrics( SM_CMONITORS ) > 1 // if > one monitor. ) { // SM_CXVIRTUALSCREEN, SM_CYVIRTUALSCREEN are the width and height, // in pixels, of the virtual screen. // SM_XVIRTUALSCREEN, SM_YVIRTUALSCREEN metrics are the coordinates // of the top left corner of the virtual screen. // The virtual screen is the bounding rectangle of all display monitors. // See also: SM_CMONITORS, SM_SAMEDISPLAYFORMAT. pRect->top = GetSystemMetrics( SM_YVIRTUALSCREEN ); pRect->left = GetSystemMetrics( SM_XVIRTUALSCREEN ); pRect->right = GetSystemMetrics( SM_CXVIRTUALSCREEN ) + pRect->left; pRect->bottom = GetSystemMetrics( SM_CYVIRTUALSCREEN ) + pRect->top; } There are articles here on Multimon which provides a good API for dealing with multiple monitors.

Thanks, that worked well. Jeff Rothenberg Project Engineer Vector CANtech, Inc.

I'll have to try that out. The SPI_GETWORKAREA seems to work but probably because i have nView on my Geforce laptop video card. It acts like one wide monitor. Jeff Rothenberg Project Engineer Vector CANtech, Inc.

It acts like one wide monitor. This must be fooling SPI_GETWORKAREA. You need to disable this sort of stuff when developing and testing multi-monitor code. Neville Franks, Author of ED for Windows.
