Urgent help needed with MultiMap!!!

Hi,
I'm new to STL, and got into some problem with it.
I need to use multimap, where "Key" is of type "long" while the "Data type"
is a "structure", which contains 3 items, including the "Key".
And later on will add insert/remove/... items from the map depending upon
the value of "Key" and a comaprision function.
I'm not able to do so, while inserting an item into map using "pair" it is
giving error: -
pair<int,struct mytest="">::pair<int,struct mytest="">' : none of the 2 overloads
can convert parameter 2 from type 'const int'

The syntax I'm using is something like this: -
typedef struct mytest{
int size;
int index;
int value;
};
...
multimap <int, mytest="">mymap;
mymap.insert(pair<int, mytest=""> (200, (200, 13, 868)));
...
Any help on this will be greatlly appreciated.
Thanks in advance!!

regards,

You need to create an instance of the struct and pass it in, what you are trying to do cannot work. What if you had three classes that all took three numbers in the constructor - how is C++ to know which one you want ? I dunno if mymap[200] = mymytest; will work for a multimap, but it's much neater for maps, that's for sure.

Urgent : Help with Visual Studio .NET C++ addin

Hi !

I'm working on a Visual Studio .NET addin written in C++. At the momment, the addin creates a new solution, adds a blank project to this solution, and adds folders to this project.

The problem is that when I try to add some files in one of the project folders, they are always added at the root of the project, and not in the specified folder.

Does anyone had the same problem ?
Is there a way to bypass it ?

Thanks a lot,
Jean-Paul

MainFrame precreate is ignored!!!!!

ns15-Jul-02 3:09

15-Jul-02 3:09

I have :

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIFrameWnd::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cy = ::GetSystemMetrics(SM_CYSCREEN) / 3; //600;//
cs.cx =::GetSystemMetrics(SM_CXSCREEN) / 3; // 800;//

This worked fine, till I changed the following (I wanted the CFormView to fit my dialog resource:

void CTrain1View::OnInitialUpdate()
{
//CFormView::OnInitialUpdate();
// ResizeParentToFit();
CFormView::OnInitialUpdate();

if( TRUE )
{
// 2 - Resize parent frame to fit our Form View
GetParentFrame()->RecalcLayout();
ResizeParentToFit( FALSE );
ResizeParentToFit( TRUE );
}
Now the app comes up full screen!!!

I need to have the form fitting behavior but also want to control the size of my app through PreCReate. Please help!

Help! need to modify this "switchview" function

ns15-Jul-02 2:53

15-Jul-02 2:53

I have SwitchView routine presently written as a member of the CMAInFrame class. I need to access this function from a view class. I cannot figure out how to call this function from CMYView:
I tried AfxGetWnd()->SwitchView but thats not right.

If theres no way to get to the function (I dont believe that!), then I'd like to modify it so that it becomes a member of the view class. This step woud really be very instructive for me, since I'm new and just now getting a feel for all these classes in the doc/view architecture.

Here is the function:

BOOL CMainFrame::SwitchView(CMultiDocTemplate *pTemplate, CRuntimeClass *pViewClass)
{
CMDIChildWnd* pChild = (CMDIChildWnd*) MDIGetActive();

if ( pChild == NULL ) return FALSE;

CDocument* pDoc = pChild->GetActiveDocument();

if ( pDoc == NULL ) return FALSE;

CView* pView;

POSITION pos;

pos = pDoc->GetFirstViewPosition();

while( pos != NULL )
{
pView = pDoc->GetNextView( pos );

if( pView->IsKindOf( pViewClass ) )
{
pView->GetParentFrame()->ActivateFrame();

return TRUE;
}
}

pChild = (CMDIChildWnd*) pTemplate->CreateNewFrame(pDoc, NULL ); //error here ERROR: Dialog with IDD 0x0082 must have the child style.

if( pChild == NULL ) return FALSE;

pChild->MDIActivate();

pTemplate->InitialUpdateFrame( pChild, pDoc);

return TRUE;
}

How to create a consol window like the output window of VC++ 6.0 ???

Raphael Kindt15-Jul-02 2:11

Hi...

How to create a consol window like the output window of VC++ 6.0 ???

For the moment I use a view derived from CEditView :

class CMyView : public CEditView {...}

And for insert text (read-only), I use this method that I've created in the view:

void CMyView::DisplayText(CString text) const
{
	CEdit& theEdit = GetEditCtrl();
	theEdit.SetSel(-2, -1);      // to insert text in the end
	theEdit.ReplaceSel(text);    // like this scrollbar move with text
}

Moreover, this method is only call from CMyDocument like this:

void CMyDoc::OnMyProgram() 
{
	CMyView* pView = (CMyView*)m_viewList.GetHead();
	pView->DisplayText("\r\nMy Programming\r\n");
}

My question: Is that clean ???
In fact, I want that the scrollbar move with text insert...

Thanks in advance...

Hello World!!! Smile | :)

To scroll down listbox programmatically, I use such code:
m_list_box.PostMessage(WM_VSCROLL, SB_BOTTOM, 0);
Try this with CEditView or it's underlying Edit Control.

how to add text in the end of the CEdit control ???

Raphael Kindt15-Jul-02 3:32

Raphael Kindt

15-Jul-02 3:32

OK thanks...

But now, how to add text in the end of the CEdit control ???
Thus, NOT replace...
curently I set the carret on the ending position with this code:

theEdit.SetSel(-2, -1);

And then I replace the ending position with text, like this:

theEdit.ReplaceSel(text);

I find that not very clean...
An Add(CString str) method must exist !!!

thanks

They are both okay, but usually we do our stuff first and then call the base class handler!
