as it is in the MSDN :

When delete is used to deallocate memory for a C++ class object, the object's destructor is called before the object's memory is deallocated (if the object has a destructor).

yep. If you want to make sure of it, just try to display something in the destructor [ with

~Foo{ cout<<"Here i destruct the object"<<endl; }

if you're running a console application].You can even display the pointer address to be really sure it is the bar and not something else.

I need to retrieve the value from a cWnd that has the focus, The value I need is m_pTypes, which is an unsigned char* value. I using the following code:

CWnd * pWnd = GetActiveWindow();
pWnd = GetFocus();

In debug mode I see the following values:
- pWnd 0x00aeea50 {CListCtrlEx hWnd=0x00000240}
- [CListCtrlEx] {CListCtrlEx hWnd=0x00000240}
+ CListCtrl {CListCtrl hWnd=0x00000240}
m_nHighlight 2
m_bSort 1 ''
m_nViewType 0
m_overAmount 1162299716
+ m_pTypes 0x00ea12d0 "ýýýýÝÝÝÝÝÝÝÝÝÝÝÝÝA"
m_nNumCols 7
+ m_ctStart {...}
+ m_headerctrl {CNewHeaderCtrl hWnd=0x00000224}
+ m_cImageList {CImageList}

How Can I retrieve that value?

Any help would be greatly appreciated.

Thank-you

You can access your value with pWnd->m_pTypes if it is a member variable. Are you using MFC in this case ?

Yes, it is a protected member variable. I tried this and it would not work.

Thanks again for your help.

Then you´ll have to make a getter for this variable. Otherwise, there is no way to access this data.

well, i'm working on a project that needs to send & receive SMS as well, so here is a procedure to follow :

1) Open the Com port, using CreateFile()
don't forget to set-up the COMMTIMEOUTS & DCB structures.

2) to send an SMS you need to send your AT command as char to your com port (modem), like this :
char c[300] = {0}, r[100] = {0}, tmp[300] = {0};
DWORD dwBytesWrite, dwBytesRead, dwTmp;

// *** INIT PHASE : SET DATA TYPE TO SMS ***
strcpy(c, "AT+CMGF=1\r\n");

and then
if(!WriteFile(hGSMPort,c,strlen(c),&dwBytesWrite,NULL)
...
don't forget to read the reply from the modem.
using ReadFile()

3) when the port is open, create a thread to read new SMS received

hope it helps

Pretty easy to do. I've implemented some code which does the same. On freshmeat.net there are a couple of opensource projects which do the same. I suggest you download them and have a look at the sources.

To access the serial port use CreateFile() + SetCommState(). It's all in the Platform SDK.

Newbie struggling with makefile and linker

Hello,

I have a problem with makefile and linker. I get error LNK2001: unresolved external symbol "int __cdecl LibFunction(char *,int)" (?LibFunction@@YAHPADH@Z), when trying to use Function that is in mylib.lib.

I have macros:
LINK_FLAGS=/machine:I386
LIBS=..\lib\mylib.lib

and I'm trying to link like this:
myprogram.exe: $(OBJS)
link $(LIBS) $(LINK_FLAGS) $(OBJS) /OUT:$@

How do I make the linker realize that LibFunction is in mylib.lib?

Regards,

Try to put your lib name and path into the Project/Settings/Link - Object/Library Modules editbox for all configurations that need it.

There is only 'General' and 'Debug' tabs in the 'Settings' of this project. I guess it's because it is a makefile-project. If I'm wrong, please correct me.

But aren't those tabs only a another way to tell the compiler and linker how to make the .exe. So what do I have to do my makefile instead of changing settings?

PS. I would do the program withaut makefile if I could, but there is so much more in it. Btw, is there a way to combine a "normal" project and makefile?

Create a project with the settings you want to use. Then select Export Makefile from the Project menu. Merge/plagerize the result with your makefile project.

hi!

I just downloaded the latest Platform SDK, however, I can't install it.
When I execute the CoreSDK-x86.msi the Setup tells me to uninstall any previous versions of the Platform SDK.

But how do I uninstall the Platform SDK (current version intalled on my computer: November 2001)?
In the Control Panel un er "Software" there is no item to uninstall the psdk...and if I choose to uninstall the psdk from the Start Menu only a html file opens

So how do I uninstall it?

MDI Child Window Maximising - Getting Large Numbers...

Hi I have an MDI application which uses multiple resizable formviews for the child windows.
When one of the child windows is macimised, opening another child window results in an OnSize message with a width and height of 32763.
(This is running on Windows 2000)

Any Ideas why this is happening, and how to prevent it???

I'm stuck with a not-more working MMCCtrl.
All of a sudden, the MMCCtrl (MMCs own control used in TaskPads) stopped to function properly.
Only thing I get is a "Object does not support this method".
Well, "this method" does work, at least on other machines with the same MMC installed, and it did on mine until short time ago.

Seems that IE is just messing it up in the HTML which loads that control.

Any ideas????
