Hi all,
We are inserting item in a tree. Whenever we insert an item, we use SetItemData(...) to store our custom data and later use GetItemData() to reteive it from the nodes.
The values are correctly retreived in case if there is no child node under a parent node,
but incase of a child the GetItemData() returns unexpected value of the parent.
Please anybody helps,Thanks.
The Phantom.

Hi,
Set/GetItemData is verified way. It not depend of nodelevel.
I am sure that you simply have confused something in the program.

I'm going to convert a program to a library. First, I delete the project(say foo.dsp) which originally create binary exe-file. Second, insert all header/cpp/resource files which are in foo.dsp into the new one.Third, compile to see how thing's going.
To my surprise, many include path errors come out to me.
PS: preprocesser definitions are always the same.
Please give me some help if you could.
TIA

Hi,
If you eant convert App to the static Lib I can suggest
folowing way:
1) Create Lib project
2) Add necessary files from App to the Lib project
while( not success)
3) Compile
4) Do some corrections
end while

Thanks for your advice.
But, I'm wondering whether there's some path variable in the foo.dsp file or not.
do you know that ?

|
|
|

Hehe,
its may be path variables, Preprocessor defs, and many other conditions.
Nobody can tell more without project files

Hi Marissa,
You can use varuious tecknikues to implement drag and drop,
but in any case you can use
HitTest and EnshureVisible to determine position
and show item in a tree control.

Hi All,
When I am trying to select the value of any of the selected node inside a CTreeCtrl, the NM_CLICK returns the value either previously selected or some other value.
Can anybody tell me how to correctly get the value selected by Left Mouse Click.
Thanks.
The Phantom.

void CBuilderDlg::OnClickTree(NMHDR* pNMHDR, LRESULT* pResult)
{
TVHITTESTINFO tvhit;
CPoint p;
GetCursorPos(&p);
m_EnvTreeCtrl.ScreenToClient(&p);
tvhit.pt=p;
HTREEITEM hItem=m_EnvTreeCtrl.GetSelectedItem();
tvhit.hItem=hItem;
m_EnvTreeCtrl.HitTest(&tvhit);
hItem=tvhit.hItem;
m_EnvTreeCtrl.SelectItem(hItem);
hItem=m_EnvTreeCtrl.GetSelectedItem();
if (hItem)
{
...
}
}
~RaGE();

You can use the code snippet, the best way is however to handle TVN_SELCHANGED (so the selection changed message) instead of the NM_CLICK
~RaGE();

Hi,
you also can use fillowing :
1) TVN_SELCHANGED
2) TVN_SELCHANGING

OK, Open your front door and take a right, walk 100 yards down the road then take a left, jog for 15 minutes until you see a shop called 'Computers for Dummies', using the door handle, gently twist and push the door at the same time. Walk in through the empty space and go to isle three. Purchase the casio calculator and install your program, perhaps that will speed things up for you  . Seriously, though either re-install windows or get a faster machine. I doubt its your program, but if it is then optimise its construction and startup code.

Sarcasm is the lowest form of wit...but the highest form of intelligence . Sorry for the sarcastic tone, just having a giggle. Anyway, I had a look in MSDN and found the Win32_StartupCommand class which may be of some use, though MSDN is very unclear about what it does and how it works. There are a whole host of other things relating to Win32_LoadOrder_blah which may be of some help, I think its a way of accessing services but I am not sure, you may have to look these things up on-line at msdn to get some examples cos there aint any with MSDN 6.0  I may be barking up the wrong tree, but its something you can look at that may be of some help, I hope. Good luck, if I find anything else, or you does, or anybody else does, post it up!

Hello everyone. I am writing a program which is going to create a new folder inside the current user's My Document folder. How do I find the path to the current user's My Document folder? ie. "c:\my documents" on Win98 or "C:\Documents and Settings\SomeUserName\My Documents" in win2000? And what should my application default to when it goes to create datafiles if run on Win95, since there is no "My Documents" folder in Win95? Default to the application's path? I was told by other developers that an application should default to the My Documents folder when creating a new datafile for the first time (like Word does).
