What I need to do is move my existing resources from the executable into separate resource DLLs, separated by language. Does anyone have links to any tutorials, guides, or other articles about resource DLLs in general?

I have no complaint with the “mentoring concept” or the marriage concept or the sex concept. But if you pay for any of those, something’s wrong.

Microsoft Press used to have a book on Localization/Globalization.
It was pretty good at the time.

I'm trying to create a popup menu for my tree control. I've got some code and the sample I have seems to use a CPoint pointer for the x and y locations of the mouse. Can I get access to a CPoint object somehow in the code I have?
void CSacmanSetupDlg::OnRclickSacmanSetupTree(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
bool bDone = false;<br />
HTREEITEM hSelectedItem;<br />
<br />
CMenu newMenu;<br />
newMenu.CreatePopupMenu();<br />
bDone = newMenu.TrackPopupMenu(TPM_LEFTALIGN,15,15, <br />
AfxGetApp()->m_pMainWnd,NULL);<br />
hSelectedItem = this->m_SetUpTree.GetSelectedItem();<br />
<br />
*pResult = 0;<br />
}
Sample I'm working from...
void CAppButton::OnRButtonDown(UINT flags, CPoint point)<br />
{<br />
CMenu menu;<br />
CMenu *submenu;<br />
menu.LoadMenu(IDR_LAUNCH);<br />
submenu = menu.GetSubMenu(0);<br />
ClientToScreen(&point);<br />
submenu->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,<br />
point.x, point.y,<br />
AfxGetApp()->m_pMainWnd,NULL);<br />
}
|

GetCursorPos() will return the current position of the mouse in screen coordinates. From memory (so i may be wrong), TrackPopupMenu() wants coordinates in client coorindates, so you may need to convert it first.

Actually, TrackPopupMenu needs screen coordinates  (your memory must be fading...  ). You can pass the results of GetCursorPos() straight to TrackPopupMenu().
However, for this app you might want to use GetMessagePos(), which returns the screen position of the mouse when the last message retrieved with GetMessage() was generated.
Cheers,
Ryan

El debugero says that Track PopupMenu is returning a zero...what gives? 
bool bDone = false;<br />
int x,y;<br />
HTREEITEM hSelectedItem;<br />
DWORD mousePosition;<br />
mousePosition = ::GetMessagePos();<br />
x = GET_X_LPARAM(mousePosition);<br />
y = GET_Y_LPARAM(mousePosition);<br />
<br />
<br />
CMenu newMenu;<br />
newMenu.CreatePopupMenu();<br />
bDone = newMenu.TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,x,y, <br />
AfxGetApp()->m_pMainWnd,NULL);<br />
if(bDone)<br />
Beep(678,46);<br />
<br />
<br />
hSelectedItem = this->m_SetUpTree.GetSelectedItem();<br />
<br />
<br />
*pResult = 0;

If this is the exact code you're using, then the problem is that you're not adding items to the menu before you call TrackPopupMenu(). You have to either call newMenu.LoadMenu() to load a menu from a resource, or call newMenu.InsertMenu()/AppendMenu() to create the menu items at runtime.
At the moment, you're trying to display a menu with no items in it.

With this code I get a menu but it's about 1 mm thick. I don't see any functions that let me adjust the size or shape of the new menu...
void CSacmanSetupDlg::OnRclickSacmanSetupTree(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
int x,y;<br />
int menuHandle;<br />
bool bDone = false;<br />
char * newItem = "Does It Work?";<br />
<br />
UINT nPosition = 0;<br />
HTREEITEM hSelectedItem;<br />
DWORD mousePosition;<br />
<br />
mousePosition = ::GetMessagePos();<br />
x = GET_X_LPARAM(mousePosition);<br />
y = GET_Y_LPARAM(mousePosition);<br />
<br />
<br />
CMenu newMenu;<br />
<br />
newMenu.CreateMenu();<br />
newMenu.InsertMenu(nPosition,MF_POPUP,menuHandle,newItem);<br />
<br />
<br />
newMenu.EnableMenuItem(1,MF_BYPOSITION);<br />
newMenu.TrackPopupMenu(TPM_CENTERALIGN,x,y,<br />
::AfxGetMainWnd(),0);<br />
if(bDone)<br />
Beep(678,46);<br />
<br />
<br />
hSelectedItem = this->m_SetUpTree.GetSelectedItem();<br />
<br />
<br />
*pResult = 0;<br />
}
I'm vexed...

You can't adjust the size or shape of the menu (not without using owner-draw anyway), but 99.9% of the time you won't have to. Windows will automatically size the menu based on its contents.
What you have done here is created a menu with a single item in it - a submenu that has no items, and you haven't given the submenu a name. If an item's name has no characters, then nothing is displayed and the menu is very thin, which is exactly what is happening.
To add useful items to your menu, use the following:
<br />
newMenu.InsertMenu(nPosition, MF_BYPOSITION | MF_STRING, ID_MENU_ITEM, strMenuText);<br />
Where:
ID_MENU_ITEM is the menu item identifier of your menu item
strMenuText is the text of your menu item ("Cut", "Copy", etc...)

Is the ID_MENU_ITEM a menu resource that I create in the resource editor? If so, what is the difference between load menu and insert menu? I'm not a work right now so I can't take a look at the documentation...

NO! As I said before, ID_MENU_ITEM is the identifier of a menu ITEM, not a whole menu. If you want to load a menu from a resource, then you have to use LoadMenu(). All this is in the documentation.

Thanks man, that sucked! I went the Load Menu route, although the instructions you gave me worked as well. I had to create a menu called ID_INITIAL_MENU. Then in the properites section, I had to check popup. Then create ID's and captions for each new popup I wanted in the menu. Once the menu was associated with a class I was able to add message maps that allow me to do something when the pop up menu's were selected. I think those were the steps I really needed. Thanks for putting up with me though...;P

Hi,
In a dialog-based application, i have a a worker
thread which read 256k data from Cdrom at one times (step).
But it failed with memory leak. Would you please
provide me a safe thread method to be used for my problem?
I see many example code of the "thread", but i don't know
which one is best for my problem.
Thanks in advance!

If you're using AfxBeginThread then it's possible to have the returned CWinThread* as memory leak.

Thanks!
but how to solve this problem (i really used AfxBeginThread function)
and there is 256K data needed read from CD and save it to a file for
each iteration step.

I don't know if this is the problem, it might work fine.
Save the CWinThread* returned by AfxBeginThread and delete it after the thread terminates.

The following is the part of the code, would you please try to
find where is my mistake?
class CEfmraDlg : public CResizableDialog
{
public:
CEfmraDlg(CWnd* pParent = NULL);
struct SToto
{
BOOL m_bToto;
};
static UINT StartThreadEfmRead (LPVOID param);
...........
bool m_bStop;
}
void CEfmraDlg::OnEfmRead()
{
m_bStop = FALSE;
SToto stToto;
stToto.m_bToto = TRUE;
AfxBeginThread(CEfmraDlg::StartThreadEfmRead, this);
}
UINT CEfmraDlg::StartThreadEfmRead (LPVOID param)
{
char buff1[100];
CEfmraDlg* ts = (CEfmraDlg*)param;
if(ts->m_scsi.EFM_open(newSparam) == 0)
{
FILE *fp;
if( NULL == (fp = fopen("cd.txt", "wb"))){
ts->m_ListBox.AddString("Open cd.txt error");
}
ts->m_ListBox.AddString("Read CD begin ...");
int count = 0;
for(;
{
count++; //256k
if(ts->m_bStop)
{
ts->m_ListBox.AddString("Read EFM data aborted.");
ExitThread(0);
break;
}
if(ts->m_scsi.EFM_read(fp))
{
ts->m_ListBox.AddString("Read Error!");
ExitThread(0);
break;
}
memset(buff1, 0, 100);
sprintf(buff1,"CD Reading - Count: %d Bytes: %d", count, count*256*1024);
ts->m_diff = buff1;
ts->ShowText();
}
ts->m_scsi.EFM_close();
fclose(fp);
AfxEndThread (0);
return 0;
}
return 1;
}

Replace ExitThread(0) with AfxEndThread(0). Don't mix up these calls when you're using MFC.
When you're exiting the thread because of some read error or abort you have to call fclose(fp) . This could be your memory leak, with the greatest probability.
Use CWinThread *pThread = AfxBeginThread(CEfmraDlg::StartThreadEfmRead, this). If your program ends before the thread exits, then you must delete pThread.
