Does MFC provide any method which will give me a list of handles or pointers to ALL open documents or MDI child windows in an MFC MDI Doc/View application?
Thanks

The CDocTemplate objects keep track of open documents. By iterating through the
registered templates, you can get the open docs associated with each template.
For enumerating views, you can do it the windows way(s) like EnumChildWindows()
or you could also use CDocument::GetFirstViewPosition()/CDocument::GetNextView()
to get the views for each document obtained as described above.
For an example of enumerating documents, you can check out the source code.
CWinApp::CloseAllDocuments() is an example.

Great! Using CDocTemplate::GetFirstDocPosition and CDocTemplate::GetNextDoc, along with CDocument::GetFirstViewPosition and CDocument::GetNextView, I was able to get everything I needed.
Thanks very much!

Hi
when i compile this:
#include <windows.h>
#include <mapiwin.h>
typedef struct _INST
{
UINT cRef;
LPMALLOC lpmalloc;
} INST, *PINST;
int main()
{
PINST pinst;
pinst = (PINST) PvGetInstanceGlobals();
return 0;
}
i get
Linking...
testmapiWin.obj : error LNK2001: unresolved external symbol _pinstX
Debug/testmapiWin.exe : fatal error LNK1120: 1 unresolved externals
pinstX is defined in MAPIwin.h
extern LPVOID pinstX;
dose any one have a idea why this won't compile...
Many Thanks
Calvin

Try adding this to your source code, in some *.cpp file
#pragma comment(lib,"mapi32.lib")
|
|
|
|
|
thanks
I tried that and stil got the same error
is this the same as adding mapi32.lib to the linker "additional dependancies" as i all ready have it added there.
Many Thanks

Ok...
Did some reading and found out what was going on..
The key is that "pinstX" is defined in "MAPIWIN.H" as "extern LPVOID pinstX;" the key is the "extern" which is apaerntly a external global so all I had to do was add..
LPVOID pinstX;
to the main file (or main header) and now it compiles..
so it now reads
#include <windows.h>
#include <mapiwin.h>
LPVOID pinstX;
//typedef LPVOID pinstX;
/* Per-instance data. */
typedef struct _INST
{
UINT cRef;
LPMALLOC lpmalloc;
} INST, *PINST;
int main()
{
PINST pinst;
pinst = (PINST) PvGetInstanceGlobals();
return 0;
}
Many Thanks

Your code compiles fine. It's the linker that is complaining. By using the extern keyword, you've told the linker that the actual declaration of pinstX is found in some other .obj file. Guess what: the linker could not find it.

hi all
I want to add a hotkey (shortcut key) s.t. when pressing alt+control+shift+p it would do something
(start ms-word with my private diary I tell my self all sorts of thins there....shhhh...)
I tried to make this shortcut keys from a desktop icon but it seems that it stopped working after a few booting of my computer.
anyway I want to succeed in that method of hot key ive been tring to do a little in c++(no mfc) program to add a hotkey using registerhotkey and the message WM_HOTKEY:
but it dont work for me at all (it seems that the shortcut keys dont activate the message WM_HOTKEY)
any help?
thanks
(ive followed the directions in this article
http://www.codeproject.com/system/nishhotkeys01.asp[^][^]
)
here is the abreviated source code of the little program for a hotkey:
int WINAPI WinMain (...){
.
.
.
RegisterHotKey(hwnd, 100, MOD_ALT | MOD_SHIFT | MOD_CONTROL , 'p');
.
.
.
}
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam){
string execstr;
execstr = ("\"C:\\Program Files\\Microsoft Office\\Office10\\WINWORD.EXE\" \"C:\\Documents and Settings\\DELL\\My Documents\\diary.jjj\"");
switch (message)
{
case WM_DESTROY:
PostQuitMessage (0);
break;
case WM_HOTKEY:
printf ("pressed hotkey");
WinExec (execstr.c_str(),SW_SHOW);
break;
default:
return DefWindowProc (hwnd, message, wParam, lParam);
}
return 0;
}

Did you check the return value of RegisterHotKey()?
Is WindowProcedure() receiving any messages?

use the following code
RegisterHotKey(hwnd, 100, MOD_ALT | MOD_SHIFT | MOD_CONTROL , 0x50);<br />
intstead of
RegisterHotKey(hwnd, 100, MOD_ALT | MOD_SHIFT | MOD_CONTROL , 'p');<br />
It requires the ASCII in the last argument. and tell me whether it worked or not.
|
|

|

thanks very much
it works now.
now I have another minor problem:
I want to run this program all the time and I dont want any window of the program to be shown (even as minimized) but the cmd window is present as long as the program is running.

Can anyone help me with building a toolbar with two vertical columns?

Depending on what you need, I can think of a couple ways. One is to just use two toolbars. Another option is to use a "dialog bar" and make the dialog template provide two vertical columns of buttons.

I would really like toolbar by itself so that the program looks professional. I may use calcFixedlayout. If you have a neat way how to do it, please do help.
thanks.

I'm afraid I don't understand what your saying. How would a dialog bar look nonprofesional?

A toolbar will wrap the buttons if you set its size appropriately.
A problem, unless there's enough buttons, is that when you resize it to the right size,
it may not fill an entire side of a window.
To get around this, I personally embed the toolbar in a control bar - the control bar always
stays the height of the window and the width of two columns of buttons. The embedded
toolbar is sized appropriately to get the two columns.

how can i resize it so that the buttons inside it wrap itself. As far as I know, it always aligns button in a single column in vertical toolbar. I tried resizing it, it still shows the buttons in single column. Help please.

Make sure the toolbar control has the TBSTYLE_WRAPABLE style.

I tried TBSTYLE_WRAPABLE. It probably works only when the toolbar is floating. When the toolbar is docked, it aligns itself in single column again. I know i have to use calcDynamicLayout and CalcFixedLayout. I do not know who to override them and what code to put in it.
Thanks every one for help though

It doesn't have to be floating.
You didn't mention MFC before, but now that you've mentioned it -
Override CalcFixedLayout()...
If you return the proper size for the bar it will work.
The width should be the size of two buttons (for two columns).
The height should be the height of the client area of the parent.
For CalcDynamicLayout() I often just route the call to CalcFixedLayout()
unless I need different functionality there - something like:
CSize CMyControlBar::CalcDynamicLayout(int nLength, DWORD dwMode)<br />
{<br />
return CalcFixedLayout(dwMode & LM_STRETCH, dwMode & LM_HORZ);<br />
}<br />

What to put in CalcFixedLayout override. I though i have to set flag for each toolbar buttion in the CalcFixedLaout function(weather the buttion is to be wrapped or not). What would that code be? Or I should simply use TBSTYLE_WRAPABLE style for Toolbar without any code in CalcFixedLayout and it should work?
Thanks again.

All you need is to return the size you want.
For vertical, two columns, something like this maybe...
CRect CliRect;
GetParent()->GetClientRect(&CliRect);
CRect ButtonRect;
GetToolBarCtrl().GetItemRect(0, &ButtonRect);
return CSize(ButtonRect.Width() * 2, CliRect.Height());
The wrapable style only needs to be set on the toolbar itself. You also don't need
separators although they can be used to aid wrapping in some instances.

I will try this code. I did try using the width function of the toolbar but that increased the width but did not wrap the buttions. I will use this approach now. I will update you how did it go.

Use Separator at the place from where you need to wrap.
I think this will help you.
