See this MSDN link: Windows Messenger API[^]

There's a scarce amount of examples available for writing a Messenger add-in. The best approach would be to write an external application that interfaces with the Messenger, and adds to it. But as for writing an authentic Messenger add-in, then sorry, nothing I can do Smile | :)

Terminating an application

Is there an MFC function to terminate an application? (like AfxAbort(), but without the ugly error message)

This line causes terminate the application:

::AfxGetApp()->ExitInstance();

I just ended up calling my CMainFrame class's OnClose() function, since that's where I'm at when I need to do it anyway, and it works fine. I tried ExitInstance first, and it didn't work right. thanks, though!!

The prefered method is to post a WM_CLOSE message. This is what happens when you close an application via Alt+F4, or by selecting Exit from the File menu. Note that this is not the same as calling PostQuitMessage().

[--HELP--] After installing the latest DX9 SDK, the DirectX panel is gone.

After installing the latest DX9 SDK, the DirectX panel is gone.
I wonder if it is normal? If so, how do I switch between retail
and debug?

When I use Dxdiag, the program reports that "d3dref.dll" "d3dref8.dll" and "d3dref9.dll" are Final Debug.

I wonder if it is normal?

C++ without virtual functions is not OO. Programming with classes but without dynamic binding is called "object based", but not "object oriented".

Dunno about normality. What even is the DirectX panel ? You mean a Control Panel applet ? I have never even had one on my computer..

I have DirectX 9.0b run-time, and the latest DirectX 9 SDK installed. The files you mentioned are marked as "Final Debug" for me also. However my DirectX games and applications work flawlessly, so I must presume that there's nothing wrong.

Mouse selection

Hi,

I have a list control with the default multiple selection style.
The problem is that if I drag the mouse over it, it will not select all the itmes, like we do for example in a CListBox class.

If I want to select multiple items, I have to use SHIFT+ Arrow key.

How do I enable the mouse doing it

Ivan Cachicatari18-Aug-04 11:02

To enable select multiple items using the SHIFT key and the mouse or special key combinations, create the control with LBS_EXTENDEDSEL style, or set this style with.

m_yourListCtrl.ModifyStyle(0,LBS_EXTENDEDSEL);

Shay Harel18-Aug-04 11:10

The problem is that :LBS_EXTENDEDSEL is for a list box.
Is there anything for CListCtrl or CListView ?

Re: Mouse selection

Ivan Cachicatari18-Aug-04 11:31

Ivan Cachicatari

18-Aug-04 11:31

Yes,

To modify this style in a CListView use:

CListCtrl& theCtrl = GetListCtrl();
theCtrl.ModifyStyle(0,LBS_EXTENDEDSEL);

or inicialize this ina PrecreateWindow function.

BOOL CYourOwnListView::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style |= LBS_EXTENDEDSEL;
return CYourOwnListView::PreCreateWindow(cs);
}

a better strtok ?

Maximilien18-Aug-04 8:30

Maximilien

18-Aug-04 8:30

just wondering, is there a better thing than strtok ( and related ) ?

I need to be able to count the number of delimiters as well as tokens; not really count but scan for them. if one one my delimiter is the space, I want to know that if I have 2 spaces, I will get an empty token between them.

for example, if my delimiter is ; and I have the following string :

text;text;;text;text

I wil get something like :

text
;
text
;
;
text
;
text

I could make my own version of it, but if such a thing exists, I'd be glad to use it.

I've just learned about the boot::char_separator which would do what I like, can I use only a subset of boost ?

Thanks.

you can just do it manually
for (
int i=1;
i<=strlen(youstring)-1;
i++
)
{
if (yourstring[i]==';')
int tokcount++;
if ((yourstring[i]==';')&&(yourstring[i+1]==';'))
int sepcount++;
}

try and tell me if this is what you want.

Variant Types

Grahamfff18-Aug-04 8:29

Grahamfff

18-Aug-04 8:29

I want to create an array of variable addresses (different types).

e.g.
void * addressArray[20]; // Is void pointer correct?

unsigned status : 4;
short data1;
long data2;
float data3;
double data4;

// Now fill the array<br />
<br />
addressArray[0] = &status;<br />
addressArray[1] = &data1;<br />
addressArray[2] = &data2;<br />
<br />
// Get the data to print it<br />
<br />
CString formatStr;<br />
<br />
formatStr.Format("Data 1 = %d", *data1);   // is *data1 correct?<br />
printf(formatStr);

Is this possible, I have heard of a type called variant but never used it.

Hi,

you can use the COleVariant[^] class or VARIANT struct . To manipulate use the CCrack class included un this example[^] (Optionally)

Thanks for your post. I have spent the day trying the new OleVariant and VARIANT types.
I found that the example project did not do what I required, so I opted for the VARIANT, but have a problem. When I display the data is is always a funny value and when I set it to to 0, then it always remains at 0. I have just concentrated on dealing with a unsigned short at present; but will want to deal with floats, doubles etc later
See code below:-

VARIANT varData[5];<br />
<br />
union<br />
{<br />
	// Signal	mess_13_tp1_w01_pitch;<br />
	unsigned short		mess_13_tp1_w01_data1; <br />
	// Signal	mess_13_tp1_w03_heading;<br />
	unsigned short		mess_13_tp1_w03_data2; <br />
	// Bit fields as 1 byte insigned<br />
	unsigned short		mess_13_tp1_w02_data_X; <br />
	unsigned short		mess_13_tp1_w02_data1_X; <br />
	unsigned short		mess_13_tp1_w02_data2_X; <br />
	unsigned short		buffer[32];<br />
}mess_13_m_tp1_display;<br />
<br />
<br />
VariantInit(&varData[0]);<br />
varData[0].vt = VT_UI2;<br />
varData[0].puiVal = &mess_13_m_tp1_display.mess_13_tp1_w01_data1;<br />
VariantInit(&varData[1]);<br />
//varData[0].uiVal = 0; // Init it, but then always 0 ???<br />
varData[1].vt = VT_UI2;<br />
varData[1].puiVal = &mess_13_m_tp1_display.mess_13_tp1_w02_data_X;<br />
VariantInit(&varData[2]);<br />
.<br />
.<br />
Etc<br />
<br />
// Now display/Edit the data<br />
for( j = 0; j < message.getNoFields(); j++)<br />
{<br />
m_cSignalList.SetItemText(j , 0, message.details[j].fieldDesc);<br />
m_cSignalList.SetItemText(j , 1, message.details[j].signal);<br />
formatStr.Format(message.details[j].display1,&message.varData[j].uiVal);<br />
m_cSignalList.SetItemText(j, 2, formatStr);    formatStr.Format(message.details[j].display2,message.varData[j].uiVal);<br />
m_cSignalList.SetItemText(j, 3, formatStr);<br />
m_cSignalList.SetItemText(j , 4, message.details[j].unitsStr );<br />
}

I use a ListCtrl to display and modify the data, hence the need to use VARIANTS.

Any suggestions to overcome this problem?

Meaning that it is in the exe's resource table? If so, are you wanting to extract the resource and save it to a separate file?

Process the WM_SETCURSOR message.

BOOL CMyView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message) 
{
	switch(pWnd->GetDlgCtrlID())
	{
		case IDC_BUTTON_1:
			SetCursor(AfxGetApp()->LoadStandardCursor(IDC_IBEAM));
                        or
			SetCursor(AfxGetApp()->LoadCursor(IDC_MY_CURSOR));
			return TRUE;
         		break;
		case IDC_BUTTON_2:
			SetCursor(AfxGetApp()->LoadStandardCursor(IDC_CROSS));
			return TRUE;
         		break;
	}
	return CFormView::OnSetCursor(pWnd, nHitTest, message);
}

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
