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

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

Ramsus

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.

Multithreaded horror..

Bob Stanneveld30-May-05 22:04

30-May-05 22:04

Hello,

I have a very strange error in my multithreaded application. The situation is as follows:

[thread 1]
I have one dialog window open, this dialog spawns 2 threads (thread 2, thread 3] when it is initialized.

[thread 2]
This thread spawns two other threads (thread 4, thread 5). After spawning those threads, it retrieves data from a buffer
The two other threads are identical and retrieve data from 2 diffenrent COMM ports and put the data in the buffer.
When data is successfully retrieved, it notifies thead 3.
Before shutting down, it notifies the monitor thread (3) and shuts down thread 4 and 5. It waits until the threads are cleaned up.

[thread 3]
Its sole purpose is to monitor thread 2 and notify the dialog when data is arrived.
This thread cleans up itself after it recieved the notification that thread 2 is stopped.

[thread 3, thread 4]
These two threads retrieve data from two different COMM ports. The retrieved data is stored in a std::vector managed by thread 2.

You may think that I have too much thread for this purpose (2 would be enough for this type of work), but this is by design. The extra monitor thread is used because this is a test application. In the real application the monitor threads do some real work.

Now for the problem. Everything works like a charm, except when I try to stop thread 2. It actually manages to stop thread 3 and 4. After that, the thread is cleaned up (the thread 2 and 3 are gone in PView thread 2 not). But then, BANG the program crashes in the middle of the following function: AfxUnlockTempMaps at the following line: pThreadState->m_pSafetyPoolBuffer = malloc(pApp->m_nSafetyPoolSize);
The error message in the output window of VS2005 is:
Unhandled exception at 0x02845922 (dbghelp.dll) in TestInput.exe: 0xC0000005: Access violation reading location 0x0152070c.

The location is always the same and no pointer is even near that address...

I noticed that the problem does not occur when thread 3 and 4 stop sending data to the buffer of thread 2. Here are some code snippets:
The call where the data is added to the buffer of thread 2

m_pConsumer->AddDataToInternalBuffer(Data);

The AddDataToInternalBuffer function

void AddDataToInternalBuffer(SERIAL_DATA& SerialData)
{
	INTERNAL_LOCK();
	m_InternalBuf.push_front(SerialData);
}

Does anybody have a clue what might be happening?

I still don't know why the problem occurred, but it was in the dbghlp.dll library when the function CheckStack64 was called. This function call was made from within the Visual Leak Detector libray and without linking to that lib, everything works fine.

how to call new dialog box(new form) by clicking a button in a current form

Re: Visual C++

Cedric Moonen30-May-05 21:50

Cedric Moonen

That's not really complicated. In your handler function from the button, just created the dialog and call DoModal:

void CYourMainForm::OnButton()<br />
{<br />
   CYourDialog Dialog;<br />
   Dialog.DoModal();<br />
}

Of course, the DoModal function will not return until the dialog has been closed.

Hope this helps

cedric code is right, but considering you use MFC.

however, you talk about forms, which reminds me a little about .NET framework. If so, prefer posting sich questions on Managed C++ Forum instead.

the code would be so :

void MyDialog::OnButtonClick() {
    Form myForm = new Form();
    myForm.ShowDialog();
}
