You have two options - maintain a list of copies to the entire document in different states, or maintain a list of actions that you can unperform.

hi,
I have been trying to include a template class into a CList object but i it does not seem to work. I have tried to put in this way in the "Population" class:
Typedef Chromosome<cgene> chromosome
CList<chromosome,chromosome> PopulationArray;
Is there any way to put a template class into another template class??
I appreciate your help. Thank you.

I'm not having problems inserting template classes in a CList:
template <class t="">
class Cell {
public :
T SetData(const T& t) {
T old = data;
data = t;
return old;
}
T GetData() const {
return data;
}
private :
T data;
};
CList<cell<int>, Cell<int> > lst;//NOTE--there *must* be a space between the right-most braces : > >
lst.

typedef Chromosome<CGene> chromosome;
CList<chromosome,chromosome> PopulationArray;
This should work fine. What error messages are you getting when you try this?

Thanks for your reply,
The error message that i've got is "no copy constructor to copy the data type Chromosome<cgene>".
For now i can't remember the complete message but i will put it in after i've copied the message.

Hi!!
I am required to develop a Windows NT Service EXE in my project. While reading through MSDN, I came across the "ATL Service EXE" option when developing ATL components.
Could anybody please tell me the the difference between the two?
Which option is preferrable?
What factors does this selection depend on?
Please help me as I am new to VC++!!!
Thanks & Regards,
Nikhil.

What does compiler error 'Float Inexact value' mean? I'm using ATL and automation.
Thanks,

Hi,
I'm using a VB activeX dll for some string manipulatation stuff. This requires that from the client (VC) i pass strings to VB Dll. What datatype should I use? VB Variant seems to work good. From the client I'm using a CComBSTR to hold value.Ideally the data should be variant but is String also supported?
Thanks,
Amit.

my app contains a menu with two item.
the 1st item (MENU_ITEM_1), opens a tree, the second item (MENU_ITEM_2) opens a
dialog(1),
when the tree is opened by (MENU_ITEM_1), i made a selection on a tree-item that pops
up a dialog(2),
so i select from menu, MENU_ITEM_2 that pops up dialog(1),
my prblm is that when i reselect from menu MENU_ITEM_1, the tree appears but
the appropriate dialog no ( the MENU_ITEM_2 (dialog1) remains ) even if i send a
"brute"
TVN_SELCHANGED to the same ITEM.....to enforce the rigth dialog(2)...
this is portion of my code: ( in fact its not a menu but buttons that pops up dialog )
portion of code that catch TVN_SELCHANGED to display a dialog for each item:
case WM_NOTIFY:
switch (((LPNMHDR)lParam)->code)
{
case TVN_SELCHANGED:
hItem = TreeView_GetSelection(hTree);
tvi.mask = TVIF_PARAM|TVIF_TEXT;
tvi.hItem = hItem;
TreeView_GetItem(hTree,&tvi);
if ( tvi.lParam == 1 )
{
if ( hSkills == NULL )
hSkills =
CreateDialog(g_hInstance,MAKEINTRESOURCE(competences_cles),hWnd,(DLGPROC)Skills_Proc);
else SetFocus(hSkills);
}
...........
portion of code that catch the buttons selection:
case WM_COMMAND:
switch(LOWORD(wParam))
{
// the famous MENU_ITEM_2(dialog1)
if ( HWND(lParam) == (HWND)hJobsButton )
{
ShowWindow(hTree,SW_HIDE);
if ( hJobs == NULL )
hJobs = CreateDialog(g_hInstance,MAKEINTRESOURCE(emplois),hWnd,(DLGPROC)Jobs_Proc);
else SetFocus(hJobs);
}
// ***** MY PROBLEM MENU_ITEM_1(dialog2) *********
// *****************************************
if ( HWND(lParam) == (HWND)hMyResumeButton )
{
if ( hTree == NULL )
{
Create_Default_Tree(hWnd);
SetFocus(hTree);
}
else
{
ShowWindow(hTree,SW_SHOW);
SetFocus(hTree);
//TreeView_Select(hTree,hSkillsTree,TVGN_CARET);
//TreeView_Select(hTree,hItem,TVGN_CARET);
//SendMessage(hTree,TVM_SELECTITEM,TVGN_CARET,(LPARAM)hItem);
}
}
so can u help me please , i can't resolve it since a lot of time... :<

I am probably mangling my attempts at getting a PARAM value into my activeX control (MS VC++ 6).. I have set MayScript, etc. and the control works otherwise, But I can't figure out how to get the PARAM Values in... need simple strings available globally... An example project would be GREATLY appreceated!!!

It's saying you have the CEditSontListDialog destructor defined in more than one place. The other place is in RR_SWallDlg.cpp (the file listed in the linker error).

Hi.
I'm trying to improve a small dialog box which is part of a large program.
The list in the dialog box has been created using a SFTTree list control(Softelvdm Inc).
I'm trying to add a pop up menu when rightclicking within the list control, but have so far been unsuccessful at it.
I've tried to cut'n'paste code from a different non-SFTTree dialog box. Although the code seems to execute correctly (when tracing during debug), nothing happens. I've included the function with the code below.
void CAlarmEditPage::OnSFTTreeContextMenu(CWnd* pWnd, CPoint point)
{
TRACE("OnSFTTreeContextMenu()\n");
CMenu menu;
if(menu.LoadMenu(ID_POPUP_MENU)) // Use the What's This? Menu
{
CMenu* pPopup=menu.GetSubMenu(0);
pPopup->DeleteMenu( 0, MF_BYPOSITION ); //Remove "What's this"-Menu-item
pPopup->AppendMenu(MF_STRING, ID_HELP, "Help on selected alarm");
pPopup->TrackPopupMenu(TPM_LEFTALIGN|TPM_RIGHTBUTTON,point.x,point.y,this);
}
menu.DestroyMenu();
}
Is the code correct? Is there anything else which might cause the menu not to appear? All help greatly appreciated.
Regards,
Ole Chr. Birkeland

Hi,
I am thinking about a freeware application, that should be able to display and manipulate images. I've looked at the more famous libraries, such as ImageGear. Until I noticed QuickTime was free to use. Does anybody know a link with some sample-code how to use this? Or where I can download the SDK? (Didn't found it @ apple). Thanks!

Hi
For a while now I've been looking for a image manipulation/processing control/DLL to add to our software. The three which have made it to my shortlist are VB Active DLLs. While writing some test applications I've noticed how much more difficult it is to write software for these in VC++ compared to VB. In particular:
1/ What takes 1 line of code in VB can take 10 or more in VC++, in setting up the correct argument types to pass to a function (eg SAFEARRAY, BSTR)
2/ Often having to pass all arguments to a function because VC++ doesn't seem to recognize default arguments?
3/ Having multiple pointers to the COM interface. eg. _ImagePtr, _ImageEffectsPtr, _ImageExportPtr, etc.
4/ A general decrease in software stability...
- Is there anyway to do this stuff with less stress in VC++? If not, is there anyway I can do this in a separate VB app and communicate with my software?
- From my limited experience ActiveX controls seem to be easier to use than VB ActiveX DLLs. Is there anyway to convert from the latter to the former? What is the point of ActiveX DLLs?
Thanks for your patience in reading my often confused ramblings
Regards
Brendan

Have you looked at Paintlib ? ( www.paintlib.de ) It's about to have a lot more image filter support ( I wrote it and will submit it shortly )

Hi guys,
The problem:
In a dialog based app, blitting a bitmap into the dialog rect.
What I did:
In the constructor this:
HINSTANCE hInstance=NULL;
HBITMAP bitmap = (HBITMAP) LoadBitmap(hInstance, MAKEINTRESOURCE(IDB_BITMAP1));
m_Bitmap.Attach(bitmap);
--
In OnPaint() this:
//Create a compatible memory DC
CDC memDC;
memDC.CreateCompatibleDC(&dc);
CBitmap* pOld = memDC.SelectObject(&m_Bitmap);
//Select and realize the palette
CPalette* pOldPal = dc.SelectPalette(&m_Palette, TRUE);
dc.RealizePalette();
//BitBlt the bitmap to the screen DC
CRect rect;
GetClientRect(&rect);
dc.BitBlt(rect.left, rect.top, rect.Width(), rect.Height(),
&memDC, 0, 0, SRCCOPY);
// Restore the DC's
dc.SelectPalette(pOldPal, FALSE);
memDC.SelectObject(pOld);
--
What is it I am missing? It's not showing up?
Thanyou.
