Hi,
I am developing a marker application. Basically allows free-hand drawing with the mouse. When i draw a line, i want the window below also to visible. I am not able to create a transparent Pen for this? i tried BS_HOLLOW, but it doesn't draw at all.

hdc = CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL);
lb.lbColor = rgbCurrent;
lb.lbHatch = NULL;
lb.lbStyle = BS_SOLID;
//hNewPen = CreatePen(PS_SOLID,10,rgbCurrent);
//SetROP2(hdc,R2_MERGEPEN);
hNewPen = ExtCreatePen(PS_GEOMETRIC,10,&lb,0,NULL);
//SelectObject(hdc,CreateBrushIndirect(&lb));
//SetDCBrushColor(hdc,rgbCurrent);
SelectObject(hdc,hNewPen);
MoveToEx(hdc, PrevX, PrevY, NULL);
LineTo(hdc, CurrX, CurrY);
DeleteDC(hdc);
........

Can anyone help?

But this code is all in Platform SDK, how do i create a NULL_PEN there. I create a BS_HOLLOW(same as BS_NULL) but it doesn't draw the line at all.

Your help will be appreciated!

How to download secured web page ?

I need to download a web page but I prefer not to use CHttpView because I do not need to display anything.
The problem is that in order to get to the page I want I need to login using a form. Using CHttpView I traced the form and found that the information passed is like :
URL: https://url.com/page.asp
PostData: ui=user&pass=pass&other=other
Headers: Content-Type: application/x-www-form-urlencoded

But still, browsing directly to https://url.com/page.asp?ui=user&pass=pass&other=other didn't work.
Is there a way to do this ?

I also would like to keep the session/connection to download other web pages from the same site (using the same cookie or whatever)

Change color of controls of a dialog

Ward31-May-05 0:39

I can change the background colors of child controls of a dialog by responding to the WM_CTLCOLORxxx messages
Example:

case WM_CTLCOLORBTN:
hBrushButton = CreateSolidBrush(RGB(255,102,15));
return (int)hBrushButton;

Now I'm looking for a way to change the textcolor as well. This for buttons, labels, listboxes, ...

Thanks in advance,

Ward

That helped me.
Thanks!

My code is now the following:

case WM_CTLCOLORSTATIC:
hBrushButton = CreateSolidBrush(RGB(255,102,15));
SetTextColor((HDC) wParam, RGB(255,255,255));
SetBkColor((HDC) wParam, RGB(255,102,15));
return (int)hBrushButton;

This results is a nice orange label with white text. Smile | :)

Depending on how finicky you are, you can do it using NM_CUSTOMDRAW.

Here's something what I did:

<br />
void CSortHeaderCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
  LPNMCUSTOMDRAW pNMCustomDraw = reinterpret_cast<LPNMCUSTOMDRAW>(pNMHDR);<br />
<br />
	  // Assume default processing<br />
      *pResult = CDRF_DODEFAULT;<br />
<br />
	  // Pre-paint stage for control; return flag so that we get messages for<br />
      // each item<br />
	  if (pNMCustomDraw->dwDrawStage == CDDS_PREPAINT)<br />
		    *pResult = CDRF_NOTIFYITEMDRAW;<br />
	  // Pre-paint stage for item; return flag so that we get messages after<br />
	  // each item is painted<br />
	  else if (pNMCustomDraw->dwDrawStage == CDDS_ITEMPREPAINT)<br />
		    *pResult |= CDRF_NOTIFYPOSTPAINT;<br />
	  // Post-paint stage for item<br />
	  else if (pNMCustomDraw->dwDrawStage == CDDS_ITEMPOSTPAINT)<br />
	  {<br />
		    CDC* pDC = CDC::FromHandle(pNMCustomDraw->hdc);<br />
		    ASSERT_VALID(pDC);<br />
		    if (!pDC)<br />
			      return;<br />
<br />
<br />
            int nColumn = static_cast<int>(pNMCustomDraw->dwItemSpec);<br />
        <br />
            // Current column is the sorted column<br />
            if (nColumn == m_nSortColumn)<br />
                 // DRAW ARROW HERE<br />
          }<br />
}<br />

Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

You can't with CListBox. You'll need to use CListCtrl instead.

Shell functions and versions ?

Ramsus30-May-05 23:07

30-May-05 23:07

Hi everybody,
I am busy writing an setup program for my application. I am using some shell functions like SHGetSpecialFolderLocation to get Program files location. The problem is that this function requires a specific version of a shell dll to be present on the system. What do I do if I install the app on a older system like NT or 98 and the version of the system dll is old ? Is there a set of redistributable shell objects that will ensure the application work on all environments or is there another solution to this problem ?
Help appreciated.

Regards

That function is available on Windows NT4 and later, and Windows 95 and later. Perhaps you were thinking of SHGetFolderLocation(), which did not come out until Windows 2000, and Windows Me.
