What is "a MFC EXT DLL"?

What's the exception? On what line of code does it occur?

sorry...it is a regular DLL using shared MFC DLL...
when I call the function DoModal() ,the dialog does not display,and the exception happens!
and the main application which links the DLL will break down immediately.
that is...

Without seeing the code that's throwing the exception, it's really hard to guess Smile | :)

the problem is that the application itself has not any exception code returns to me too..when I call the DoModal() funtion,the application will look like a dead loop,you can not do anything at all...that's the problem D'Oh! | :doh:

but thanks Mark Salsbery anyway.you are a good man.. Smile | :)

3D array

Hi,

How to initialise a 3D array through a function?

int a [2][2][2] = { { {0,0}, {0,0} }, { {0,0}, {0,0} } );

or...

  int a [9][7][5];
  initialise (a,9,7,5);

  ...

void initialise (int ***a, int n1, int n2, int n3)
{
  int i,j,k;
  for (i = 0; i < n1; i++)
  {
    for (j = 0; j < n2; j++)
    {
      for (k = 0; k < n2; k++)
      {
          a [n1][n2][n3] = 97;
      }
    }
  }
}

Tada!

Note I initialise to 97. You hopefuly know more about what you want to do than I do, and can do things better. If not, go back to bed - you'll achieve more.

Iain.

Did you disable the error checking feature of your mental compiler? Poke tongue | ;-P

Please don't blame me, remeber: "this is going on my arrogant..."

Registry Vs Ini

I have an MFC application that reads/writes the address
and phone nos of employees of a company to INI file...

YOU have only FEW LINES OF CODE FOR THIS...

You need to use only GetPrivateProfileString() and WritePrivateProfileString()....

What IF I USE REGISTRY TO STORE THIS???
............WILL IT BE DIFFICULT?

It depends to you if you want to ask again and again(like ini files) its difficult but if you want to learn it yourself no its easy.

Re: Registry Vs Ini

CPallini5-Nov-08 0:10

Again, as I said to you, many, many, many, many, many times, the registry shouldn't be polluted with such kind of info.
That said, if you really, badly, want to do that, it is not difficult, really.

You use the registry to store application related information in it (application settings, usually). An INI file should be OK-ish, but then you would be better of using a database if you expect the data to grow over the time.

Hi all,

i m using a TreeCtrl in CTreeView Derived class.
use this to insert item in TreeCtrl.

void CSideTree::OnInitialUpdate()
{
	CTreeView::OnInitialUpdate();

	CTreeCtrl&  trCtrl = GetTreeCtrl(); 

	trCtrl.ModifyStyle(0,WS_VISIBLE |  WS_CHILD | WS_BORDER| WS_TABSTOP|TVS_HASBUTTONS|TVS_LINESATROOT |TVS_INFOTIP);

	HTREEITEM parent1=trCtrl.InsertItem( _T("Parent1"),TVI_ROOT ); 	
	trCtrl.InsertItem(_T("Child1"),2,2,parent1);
	trCtrl.InsertItem(_T("Child2"),2,2,parent1);
	trCtrl.InsertItem(_T("Child3"),2,2,parent1);
	trCtrl.InsertItem(_T("Child4"),2,2,parent1);

	HTREEITEM parent2=trCtrl.InsertItem( _T("Parent2"),TVI_ROOT );	
	trCtrl.InsertItem(_T("Child5"),2,2,parent2);
	trCtrl.InsertItem(_T("Child6"),2,2,parent2);
	trCtrl.InsertItem(_T("Child7"),2,2,parent2);
	trCtrl.InsertItem(_T("Child8"),2,2,parent2);

}

Here if i select any item than it diplayed in blue box i mean display selected.

but the blue box size is greater than the size of item text in case of parent selection, and in case of selection of child the blue box size is proportianate to child item text.

if this possible to show selected employee blue box according to its text.

please help me for this.

thank in advance.

I've looked at a tree control I have in my code, with linesatroot set.

Selecting a root item gives my the same sort of selection as selecting a child item. The blue background is a *little* bigger than the text, but going no wider than that.

Try putting a tree on a dialog, and using different styles in resource editor's preview to see the selections there.

Then have a look at your CTreeView's constructor, and follow it down to CCtrlView::CCtrlView's constructor and see what styles are used. You may see something that shows a difference.

Then GET an idea about it. Look in your CMyApp::InitInstance function, and you'll see that your program uses the CTreeView class. Look in the documentation (MSDN), search for CTreeView, and you'll see that it inherits from CCtrlView, which in turn inherits from CView.

You can search the source directorys for MFC for CTreeView::CTreeView and put a breakpoint in the constructor. That should help you see the path of creation of your view class.

Iain.
