Especially for an MFC application. Using interrupt 0x21 to display a string at a command prompt is easy enough, but not very useful. I can remember back when we used to write directly to video memory. Color was at B800:0000, and monochrome was at B000:0000.

B800:0000, hmmmmm i remeber this number, once i tried to save the content of the screen.it came out well, but i tried in C.

Some of them *might* work. Most probably won't, however. Doing simple things like adding numbers can be done via _asm, but calling functions and most things Windows-specific (e.g., messages, GUI) are not trivial.

__asm int 3<br />

A hardcoded breakpoint.

#pragma optimize("y", on) // Force use of frame pointers
DWORD GetMyReturnAddress()
{
	DWORD ReturnAddress;
	_asm
	{
		mov eax, [ebp+4]
		mov dword ptr[ReturnAddress], eax
	}
	return ReturnAddress;
}
#pragma optimize("", on) // Resets the optimizations

Returns its own return address. I believe VC>6 has a intrinsic function to get a functions return address.

Customizing a toolbar

Ward10-Jan-06 0:58

Ward

10-Jan-06 0:58

I've used the following code to create the toolbar window:

<br />
hToolbar = CreateWindowEx(0,TOOLBARCLASSNAME,"MyToolbar",CCS_ADJUSTABLE|WS_CHILD|WS_VISIBLE|TBS_TOOLTIPS,0,0,0,0,hWnd/*this is a dialog*/,0,g_hInstance,NULL);<br />
SendMessage(hToolbar, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);<br />
SendMessage(hToolbar,TB_SETBITMAPSIZE, 0,(LPARAM)MAKELONG(32,32));<br />
SendMessage(hToolbar, TB_AUTOSIZE,0,0);<br />

I've added some bitmaps to the toolbar using several calls of

<br />
SendMessage(hToolbar,TB_ADDBITMAP,1,(LPARAM)&bit);<br />

with bit of type TBADDBITMAP
Finally added all my buttons to the toolbar using

<br />
SendMessage(hToolbar, TB_ADDBUTTONS, NUMBEROFTOOLBARBUTTONS, (LPARAM)&tbb);<br />

I've added 5 buttons to the toolbar. The toolbar is perfectly visible and I've even managed to show a toolbar for each button by returning the appropriate data in the TTN_GETDISPINFO notification message.

Now when I send the TB_CUSTOMIZE to the toolbar, I receive following notifications:

TBN_BEGINADJUST: I simply return TRUE here

Then 7(?!: I have only five buttons) TBN_QUERYINSERT notification
I've printed the iItem value of the structure NMTOOLBAR for each notification:
iItem = 5
iItem = 5 (why is this one send twice)
iItem = 4
iItem = 3
iItem = 2
iItem = 1
iItem = 0
I return TRUE for each TBN_QUERYINSERT.

And finally I get the notification TBN_ENDADJUST.

Now where did the notifications TBN_QUERYDELETE and above all TBN_GETBUTTONINFO gone too??
I hope someone can help me out here,

kind regards,

Ward

looking for a Grid Control

hello every one.

my question may look *stupid*, but i'm completely aware of this.

i'm looking for a grid control that i could use in a MFC project.
As i never nedded grids in MFC before, i never searches for one. it seems that MFC library don't provide any grid control.
i already had a look at Chris Maunder grid, but wondered if there was a simple (very basic) one... i don't need much than lines, columns - and so cells to write in...

anyone ?

but thanks for the link anyway.

Hey tox !
Maybe you can use the MSFlexGrid ActiveX control ? It is quite simple and will probably do what you need. To use it, go into project -> Add to project (if I remember correctly) and there you have to look a little bit to find the MSFlexGrid control.

Yep that's true but when you need to do some very basic operations, you don't really need a good documentation (the functions names talk by themselves Wink | ;-)
