I am not sure about this: When I have a DLL and an EXE compiled with VC, and the EXE loads the DLL, does each have it's own instance of the C runtime (i.e. the global variables like stdin, stdout, the heap, etc.)? Does this depend on compile settings?
TIA

Yes, that is why you should avoid using free() and the delete operator on pointers received from a dll.

Depends on compile settings[^]. If you choose to dynamically link CRT in all your modules (exe and dlls), it will be shared between them and it is safe to pass objects between modules.

Hi,
Yes, you need to load that Accelerator table.
HACCEL gAccel; //Declare in header file
//Add this code to the OnInItDialog of your dialog class
gAccel = LoadAccelerators(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDR_MYACCEL));
//Add this code to PreTranslateMessage
if(TranslateAccelerator(AfxGetMainWnd()->m_hWnd,gAccel,pMsg))
return FALSE;
This should work....
Thanx and Bye

Hie Friends,
I am having one console kind of applicaion , Want to debug it during run time. It should ask or through a dialog box whenever exception occures(Here I am directly running exe ..not thr MSDEV)..I think it's possible thr CRT library but don't know how?

_asm int 3
this shows the dialog box to select the debugger you want. Is this wot you are looking for ?

I am looking for strategies for using tree controls. The goal is to extend the CTreeCtrl (or maybe even build a new custom CWnd descendant tree control) in a way that makes it easy to use, and that hides away most of the uggly struct and message tweeking needed.
At init I would want to add one single node, the root, to the tree control. And as user expands nodes, the tree would ask the node to list its children. For the tree to be able to ask nodes for children, we need some kind of "class ITreeNode" interface. Implementing this interface would enable an object to be represented as a node in the tree. And the object would itself be in charge of how it should be represented in the tree.
The tree this way visualizes the object structure in memory, which is a fair approach imo.
The treenode interface could look something like this...
class ITreeNode<br />
{<br />
virtual CString GetTreeLabel() { return "Default"; }<br />
virtual void GetTreeChildren( CTreeNodeList& L ) {}<br />
virtual int GetTreeImage() { return 0; }<br />
virtual int GetTreeImageSelected( return GetTreeImage(); }<br />
}
Did anyone experiment with anything like this?

Hi,
I have some problem with the tooltip control. I have enabled the tooltip control for my DialogBOx. I have drawn little boxes on to my Dialog Box. On each Box I have given different Tooltip Text in WM_MOUSEMOVE. Every thing is working fine but in some places Tooltip is blinking. I mean text is appearing and disappearing very fastly. But in other places on Dialog Box tool tip is stable. Can any one tell me What is happening ?
Thanks & Regards,

Hi,
R u using the RelayEvent(pMsg) in the dialog's PreTranslateMessage, if so then check the rect size for that particular control which is blinking with the one which you would have used while creating the tooltip using the AddTool function. Have a look @ CPropertySheet::GetTabControl @ msdn, it does have an example on using the tooltip control

Hi,
Here i am providing the steps
In Dialog's header add
CToolTipCtrl tooltip;
in Dialog's on initdialog add
tooltip.Create(this,TTS_ALWAYSTIP);
CWnd *pWnd = GetDlgItem(IDC_BUTTON_BC1);
tooltip.AddTool(pWnd,"Hello Testing ",NULL,NULL);
Add the PreTranslateMessage for the dialog and add the following code
tooltip.RelayEvent(pMsg);
This will work. I think you shouldn't you on mouse move

Hello,
You can simply take the handle of the SystemMenu using GetSystemMenu and remove the Move menu. The code goes like this...
void CMainFrame::DisableMoveWindow()
{
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
pSysMenu->RemoveMenu(1, MF_BYPOSITION);
}
}
Call this function in the OnCreate of CMainFrame()

If you want to stick to APIs, you call MultiByteToWideChar() to go from ANSI to UTF-16, then WideCharToMultiByte() to go back to UTF-8.
