Do I need to do this again for individual class?

You can use the same UTILITIES_API macro on a class.

The point is to only export from one module, the module where the actual
static instance(s) exist. All other modules should import.

2 dim numbers..

_80865-Aug-07 7:54

_8086

5-Aug-07 7:54

int* pInt = new int[2*3]; 6 elements

So you can access it like pInt[0],1,2,..

now i want to acess it as a 2dim.
for example,
0 1
2 3
4 5

Or

0 1 2
3 4 5

i have declared a pointer like int (*pintPtr)[2][3];

Now how do I assign this to pInt?

something like ,
pintPtr=((int*)[2][3])&pInt;?

This do not work. Please help.

Dear All
I want to write one DLL. for this purpose, I add one static library to project.
When I compile the program I get following link error.

INK : fatal error LNK1104: cannot open file "nafxcwd.lib"
Error executing link.exe.

But when I add the path of nafxcwd.lib to my lib file paths I get 716 errors.
Do you know how I can remove this problem.

Highlight text in static control

I want to highlight part of the text in a static control. I subclassed an existing dialog which can do the trick to one of it's built in controls. However, changing the functionality of the dialog box requires me to do it myself.

The resource code for the control:

CONTROL "", 1027, STATIC, SS_LEFT | WS_CHILD | WS_VISIBLE | WS_GROUP, 21, 103, 190, 69

Spying on the control under normal operation does only reveal the messages WM_GETTEXT,WM_SETTEXT and WM_GETTEXTLENGTH. Although the intended highlighting is actually visible in the control, no other messages are received, which is very confusing to me.

I think if you use of CEdit control is better than to CStatic but if you want on the CStatic you can derived CStatic.

Thank you.

I cannot use CEdit, because I use a 3rd party dialog, and the control is already there.
The only thing I can think of now is creating another control right above it, but only as a last resort.

Hamid_RT5-Aug-07 19:02

So I think easy way is use of a CStatic derived then you can use of WM_ERASEBKGND or WM_PAINT for show values of control then if you need to highlight a section of text use of SetBkMode (in fact you work with four function SetTextColor/SetBkColor/DrawText/SetBkMode).;)

You can create derive class of CStatic and do following:

1. Add in the message map

<br />
   ON_WM_CTLCOLOR_REFLECT()<br />

2. Change Text color in handling function

<br />
   HBRUSH CMyStatic::CtlColor(CDC *pDC, UINT uiCtlColor)<br />
   {<br />
       pDC->SetTextColor(/* Set color what you want */);<br />
       pDC->SetBkMode(TRANSPARENT);<br />
<br />
       return (HBRUSH) GetStockObject(NULL_BRUSH);<br />
   }<br />

Good luck.

Splitter in MDI Frame

Hi I am trying to split the MDI client window(not child).Like this GUI:
http://www.smidgeonsoft.com/images/PEBrowsePro945x689.jpg
In the left side there is a treeview and the right side there are MDI windows.

I can use splittter in SDI application wtih this code and it can split:

<br />
class CMainFrame : public CFrameWnd<br />
{<br />
  ...<br />
protected:<br />
  CSplitterWnd m_wndSplitter;<br />
  ...<br />
};<br />
  <br />
// SAMPLES\CH03\splitter<br />
// MainFrm.cpp : implementation of the CMainFrame class<br />
<br />
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, <br />
	CCreateContext* pContext) <br />
{<br />
 CSize minWindow(10, 10);<br />
 <br />
  // These variables must both be 1 or 2 for dynamic splitters.<br />
  int nRows = 2, nColumns = 1;<br />
	  <br />
  return m_wndSplitter.Create(this, nRows, nColumns,<br />
	minWindow, pContext);<br />
// <br />
}<br />

But this doent work with MDI application.
I can't divide MDI client window. I tried this:

<br />
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)<br />
{<br />
	CSize minWindow(10, 10);<br />
 <br />
  // These variables must both be 1 or 2 for dynamic splitters.<br />
  int nRows = 2, nColumns = 1;<br />
	  <br />
  m_wndSplitter.Create(this, nRows, nColumns,<br />
	minWindow, pContext);<br />
<br />
	return CMDIFrameWnd::OnCreateClient(lpcs, pContext);<br />
}<br />

But it gives run time error about ASSERT(pContext != NULL);

How can i divide MDI client window with splitter so i can insert left side a treeview(static/locked) and in the left side i can show view windows..

I couldnt find the solution.
I am looking for your answers.
Thanks...

But i don't understand the code.

Is there a way to this with MFC?

If you send me an email, I'll send you (and anyone else interested) a VS2005 project that does this.

I was going to submit it as an article but it's simple and I can't think of anything to write about it. Smile | :)
