CListCtrl data storage

What technique would be used to store items in a multi-column CListCtrl?

Would a vector inside a vector work? I need to override the operations of a CListCtrl and store each item added in a seperate array also, instead of just the default builtin storage.

If I have made sense and someone could point me in the right direction I would appreciate it Smile | :)

Thanks

Why not just an array of structures?

Nope won't work, I mean it would work, but it's not the solution I want.

I want the control generic enough that I can add/remove columns. I don't imagine the control itself uses a fixed structure...otherwise how would you support variable columns?

Cheers Smile | :)

Why don't you use Chris Maunder's grid control[^]? It looks like his control will be much beter for your application... I use it every where a CListCtrl is needed because it is so flexible and I have packaged it in a dll so it is not that difficult to add to my project...

CView OnDraw

This may be overly simple, but the solution has eluded me and research has come up with nothing.

I have a CView derived class. This class's only job is to display nothing. Smile | :)

I'd like to insert the text: "There is no data to display in this view" in the view. Centered, at the top.

I know I have to override OnDraw. I know I have to use TextOut. How do I get the text to use the system font, and center it?

Thanks!
Frank

Get mouse coordinates

13-Feb-04 12:25

I have a derived CListCtrl in which I handle a double click event, but I need to find out which item was clicked on (if any).

From the function below is there any way I can get mouse coordinates from HMHDR??? I need to pass this info onto HitTest() but it doesn't appear likely I can get mouse coordinates from the parameters below???

CListCtrl::OnDblclk(NMHDR* pNMHDR, LRESULT* pResult)

Should I use PeekMessage and get the coordinates of the mouse when the last message was fired off???

What method should I use?

Thanks

Cheers Smile | :)

If you look closely in the MSDN docs, you'll see that NM_DBLCLK for listviews, actually sends a NMITEMACTIVATE*. NMITEMACTIVATE* info = (NMITEMACTIVATE*)pNMHDR

(There's a NMITEMACTIVATE::iItem that'll interest you, I'm sure... Smile | :)

Quick Question

Nick Parker13-Feb-04 11:13

Nick Parker

13-Feb-04 11:13

Ok, I am stumped here. I have an ActiveX COM dll written in VB6 that is returning an array of doubles. I am using the Class Wizard to import the typelib. so I can call a series of methods one of which returns array of doubles. The class wizard writes out both the .h and .cpp files for me, however it comments out the one method that is returning the array doubles saying:

// method 'GetNum' not emitted because of invalid return type or parameter type

I found a kb article telling me to use the ITypeLib viewer so I can manually write the method into the header and cpp files. This is where I am stuck. The ITypeLib viewer shows the method as such:

[id(0x60030004)]<br />
HRESULT GetNum([out, retval] SAFEARRAY(double)* );

Any help for writing the guts to make the InvokeHelper call would be much appreciated.

This is what I was initially trying:

SAFEARRAY* _Moses::GetNum()
{
	SAFEARRAY* result;
	InvokeHelper(0x60030004, DISPATCH_METHOD, VT_R8, (void*)&result, NULL);
	return result;
}

TIA.

just a wild suggestion

try returning SafeArray of VARIANT instead of doubles
