Use a debugger and get a stack trace of what the thread is doing when it hangs.

The CCS_LEFT (or CCS_RIGHT) styles will make it vertical on the left or right edge.
The TBSTYLE_WRAPABLE style will allow multiple rows of buttons.

ToolBar controls are windows so you can move/resize them with MoveWindow(), etc.
THere are messages to get button sizes so you can ccalculate the dimensions required to get
two rows of buttons. It's all here in the SDK...

Is LPTSTR a char pointer?

Hello everyone!
I'm debugging a program, and, I'm viewing my own binary file in a hex editor for the first time, and that somehow makes me happy... (#define __NO_LIFE_GEEK__) Laugh | :laugh:

Now... Until byte 8 it's alright, but after that it's supposed to write a LPTSTR containing the following text:

You need a SSE2-enabled processor in order to run this program.

However, the 9th char is 03h, which doesn't look like a Y (59h)... I'm writing it like this:

// Get text in CEdit
m_em_errorMsg->GetWindowText(_tempString, m_em_errorMsg->GetWindowTextLength());

// Write it
out.Write(_tempString, m_em_errorMsg->GetWindowTextLength());

(_tempString being the LPTSTR)

So I was wondering if I should write it some other way... Am I wrong? Thanks! Laugh | :laugh:

If unicode is defined LPTSTR is a wchar_t*, otherwise it's a char*.

CTreeCtrl CheckBox

JBAK_CP27-Oct-06 15:19

Hi...I have a dialog box with a tree control that has check-boxes in it. What I need to do is, when any of the check-boxes in the tree control is checked, I need to do some processing, and for now let's just say, I need to put up a messagebox. I added a function for the 'NM_CLICK' message to intercept the left button clicks in the tree control, then I do a 'GetCheck' to see if the button is checked.

When I check the box, the 'GetCheck' function returns a 0 but a checkmark appers in the box. When I uncheck the box, the 'GetCheck' function returns a 1, and the checkmark is removed from the box. So this isn't really helping me figure out when the box is checked and not.

Any help would be greatly appericated.

Here is my code for the 'NM_CLICK'

void CDirectoryCheckDlg::OnClickTree1(NMHDR* pNMHDR, LRESULT* pResult)
{
CPoint pt;
GetCursorPos(&pt);
m_testTree.ScreenToClient(&pt);
UINT uFlags;

HTREEITEM ht = m_testTree.HitTest(pt, &uFlags);

if(ht != NULL)
{
// There is an item under the cursor.
m_testTree.SelectItem(ht);

// See what exactly was under the cursor:
switch(uFlags)
{
case TVHT_ONITEMSTATEICON:
{
// It is the icon (checkbox)
BOOL chkbox = m_testTree.GetCheck(ht);
if(chkbox)
MessageBox("Button is checked");

//CString str;
//str.Format("%d",chkbox);
//MessageBox(str,NULL,NULL);
break;
}
case TVHT_ONITEMBUTTON:
// It is the button
break;

}

}

*pResult = 0;
}

When the control issues the NM_CLICK notification, it hasn't changed the state of the checkbox yet.

You might try looking at the TVN_ITEMCHANGED[^] notification. Also look at the general tree control article here[^], especially the section entitled Working with state image indexes.

Return from function

This code works fine, but as I learn more about VC++ I wonder if it is OK. I think index exists only within the function, but I'm not sure if it can be returned to targetPrice without problem. There has been no problem so far, but my program isn't finished yet. (basePrice is global.)

int q = GetIndexForPrice(targetPrice );
...
...
...
int CTradingdemoDlg::GetIndexForPrice(double price)
{
int index;
index = (price - basePrice)/ .0025;
return index;
}

Thanks

Yes but int CTradingdemoDlg::GetIndexForPrice(double price)
and
return index;
is handled by the compiler by "copying" the value from the index variable inside the function into the value of the variable outside the function that receives it "int q".
