Hi,

Isn't IDC_APPSTARTING what you're looking for?

Hi,

The wait cursor is an arrow with a small hourglass beside it.

IDC_WAIT represent only hourglass,

Using MFC?
Here's one way...

Add a progress control to the dialog resource.
Add a CProgressCtrl object to the dialog class:

CProgressCtrl m_StatusProgress;

In the dialog class OnInitDialog() function set up the progress control:

m_StatusProgress.SetRange32(0,100);
m_StatusProgress.SetPos(0);

As progress progresses (haha) calculate the percent done and notify the progress control:

m_StatusProgress.SetPos(percentdone);

Hi all,

i have 2 dialogs, dlg1 & dlg2 in both of them i use the same code:

BOOL CDlg1::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
        if (!m_bCondition)
	{
	    ::SetCursor(::LoadCursor(NULL, IDC_WAIT));
	    return TRUE;

	return CDialog::OnSetCursor(pWnd,nHitTest,message);
}

BOOL CDlg2::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
        if (!m_bCondition)
	{
	    ::SetCursor(::LoadCursor(NULL, IDC_WAIT));
	    return TRUE;

	return CDialog::OnSetCursor(pWnd,nHitTest,message);
}

problem is that i see the hourglass when mouse is over dlg1, but i don't see the hourglass when mouse is over dlg2????

what am i missing? should i implement an other message?

thanks in advanced

the method OnSetCursor is being called on both dialogs, but the problem is that i can see the hourglass on dialog1 when mouse is over it, but i see only an arrow (not hourglass) on dialog2 when mouse is over it....

?

Thanks.But if i drag and drop the folders in the tree control they should be also be copied into the explorer at the same time.But dropping of folders is not working properly.(My application displays the explorer in the form of a tree ,so that if we click on the tree we will be opening the folder and files what we require).

Thanks

I have a MDI Project

With a MainFrm (1)
There i open Child-Windows of type CMDIChildWnd (2)
A View of element as type CFormView (3)
And the content of the View is a Dialog (made with the Ressource Designer) (4)

If i start the applic and hit a key on the ChildWindow. Which element does get the OnKeyDown Event?

2 & 3 does it not get.
It's logic that the "highest" Element receive the message -> 4: The Dialog

But i "linked" myself the Dialog to the CFormView ...
I saw that it's possible to create directly the CFormView from out the Designer with "Add Class"

Now i don't have a reaction if i hit a key on the Childform
Is it absolute necessairy to create the CFormView with the Designer?

In my CFormView i have

afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);<br />
<br />
BEGIN_MESSAGE_MAP(TheViewClass, CFormView)<br />
  . <br />
  .<br />
  .<br />
  ON_WM_KEYDOWN()<br />
END_MESSAGE_MAP()<br />
<br />
void TheViewClass::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)<br />
{<br />
  CFormView::OnKeyDown(nChar, nRepCnt, nFlags); // BREAKPOINT HERE<br />
}

Is it the right procedure to make ChildForms ?

Big thanks

The event goes to the elemenet that has the focus.
Check differences between onchar and onkeydown events....

Ok i see, that seems logic

So i need to have in each class, that has the focus, a Message-Handler for KeyDown with the corresponding afx_msg On_KeyDown

If i want catch a KeyDown on an CEdit Textbox, i need to derive a class from CEdit that
has a OnKeyDown ...

correct? WTF | :WTF:

Can i say this->getParent()->getParent() to access the MainForm ?

Many thanks ! Smile | :)

All these questions aren't in MFC Books, so it's hard to find a resolution by myself Unsure | :~

Language independent in Dlls

Normal Dlls are language dependent or Not ?
can we use C dll in C++ and viceversa ?

I read that Com Dlls Are Language independent And Normal Dlls Are Not.
Is it True ?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
