Hi,
I am useing CTreeCtrl class to build tree. I want to add CString as a additional parameter(LPARAM) to leaf node. How can I add/retrive LPARAM?
For Insertion I am Using:- tree.InsertItem("Employees", 0, 0, TVI_ROOT);
And For retrival I Am using:- HTREEITEM hCurSel = tree.GetNextItem(TVI_ROOT, TVGN_CARET);
Please suggest If I need to use different method for it or modify above method for add/Retrive LPARAM.
Thanks:-
Mike

What about SetItemData[^] and GetItemData [^] methods?

Hi,
I am not sure about SetItemData() and GetItemData() will solve my purpose. I want to send some CString value with each leaf node. e.g If you insert node 'Employee1' in the tree I will add 'EmployeeId1' as a LPARAM. So that next time when i retrive the node data I need to get LPARAM(Id associated with leaf node) somehow. Please suggest how this can achive?
Thanks:-
Mike

I'm pretty confident about (I trust in your skills  ).
With SetItemData you may store a pointer to your string (the string should not vanish in the meantime...). With GetItemData you may get back such pointer.

As CPallini suggested, you should use SetItemData and GetItemData, these can store and retrieve a 32 (or 64?) bit value, so you can't use a string, BUT you can either use a pointer to a string OR maybe an index into an array of strings, of course you will have to maintain these somehow, so if you remove an item you also manually need to remove the string or when you add the item you will have to add the string.

Hi,
I've created a animated cursor which is 32x32 RGB/A. I tried to load it in my project (VS6) but it's not loading. Here are the steps I've done plus some code:
1. I've add my cursor (named 'OrangeWait.ani') in res folder,
2. defined new ID for it in 'resource.h'
#define IDR_WAIT_CURSOR 124<br />
3. added line in *.rc file
IDR_WAIT_CURSOR ANICURSOR "res\\OrangeWait.ani"<br />
4. and added some code for testing
HCURSOR hCWait = ::LoadCursor(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_WAIT_CURSOR));
if(!hCWait)
{
AfxMessageBox("Can't load Wait cursor!");
return;
}
HCURSOR hCStandard = ::LoadCursor(NULL,IDC_ARROW);
if(!hCStandard) AfxMessageBox("Can't load Standard cursor!");
SetCursor(hCWait);
Sleep(3000);
SetCursor(hCStandard);
When I start the app I get message "Can't load Wait cursor!".
Any idea?
Thanks...

Just worked out.
It seems I forget to rebuild.
Funny.
|

It's odd!!!
I've changed the animated cursor for another one and replace it. Rebuild and back to "Can't load Wait cursor!" message.
I've double checked everything but no, still wont work. Now it seams as rebuilding isn't the issue here.
I even try to go back but to my original ani cursor still can't load it?! Then I tried to import animated cursors in the following way:
- On Insert Resources dialog box clicked Import
- Imported my animated cursors
- Specified 'ANICURSORS' as type, and clicked 'OK'
, but this too didn't give desired result. The same msg displayed.
Did anyone successfully added animated cursor (32x32 RGB/A) and got it to work in VS6? If so how?

I found the new way to succeed, only this lines of code do the job
HCURSOR hCursor = LoadCursorFromFile("res\\AnimatedCursor.ani");
if(hCursor)
SetCursor(hCursor);
Off course 'AnimatedCursor.ani' is the name of my source file.
But another problem appeared when running under release mode, cursor is not loading. Why?
It's a little sadly when talking to my self, isn't it?

Well I can get really stupid some times can I?
The file needs to be distributed along with application or it can not find and load it.
Obviously if I want it to work I need to go back and include my ani cursor in my resource.
But I cant get it to show (see previous posts). Does anybody know the solution to my problem?

If it's for writing bulk logs, go for mysql.

What problem? How do you implement it.
You need to google first, if you have "It's urgent please" mentioned in your question.

I have Two Dialog box. Abc and Def ok. From Add button of Abc i have created Def Dialog box. I need to do some work in Abc on OK of Def.
CODE:
// Abc.cpp
#define USER_MSG WM_USER + 100
BEGIN_MESSAGE_MAP(Abc, CDialog)
//{{AFX_MSG_MAP(Abc)
ON_MESSAGE( USER_MSG, DoSomeWork )
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
void Abc::OnAdd()
{
Def d;
d.ptrParent = this;
d.DoModel();
}
void Abc::DoSomeWork()
{
}
/// From def.cpp
void def::OnOK()
{
if( ptrParent )
::sendMessage( ptrParent->m_hWnd, WM_USER + 100,0,0);
// i can do like ptrParent->DoSomeWork() but i wants to user USER MSG.
}
Thank you for your interest.

Why you need messages for this purpose??
You can simply do something like this..
void Abc::OnAdd()
{
Def d;
d.ptrParent = this;
if(d.DoModel()==IDOK)
{
...
}
else
{
...
}
}
I hope it helps..
BTW: Plese use code block button below posting area for posting code snippets.
Regards,
Sandip.
