Ok, so you have a #include hierarchy like this:
stdafx.cpp
|
\---stdafx.h
|
----afxv_w32.h
|
\---comdef.hIs that right?

Sure, use:

Hi,
I am using a CRichEditCtrl in an MFC application, it is being used for an output window. I now require to have a 'gutter' or margin area to the left of the rich edit control, on which i need to draw icons (one per line) in this gutter area. It needs to look similar to MS-developer studio editor where the grey area on the left shows an icon such as a bookmark.
<br />
e.g.<br />
|-------------------------------------<br />
| | My text is here <br />
| | <br />
| | <- Left is a gutter area <br />
| | <br />
--------------------------------------<br />
Any idea on how to do this please? I have trawled the web and see lots of samples, but none that do this or similar.
Any help would be much appreciated. Thank you.

I can't seem to undock my CDialogBar. It creates the dialog bar, and docks it to the left side of my main frame, but I can't drag it away. I'm not quite sure what's wrong. Any ideas?
Here's my code:
<br />
class CDlgTree : public CDialogBar<br />
{<br />
DECLARE_DYNAMIC(CDlgTree)<br />
<br />
public:<br />
CDlgTree(CWnd* pParent = NULL);
virtual ~CDlgTree();<br />
<br />
enum { IDD = IDD_DLGTREEBAR };<br />
<br />
protected:<br />
virtual void DoDataExchange(CDataExchange* pDX);
<br />
DECLARE_MESSAGE_MAP()<br />
};<br />
<br />
<br />
if (!m_treeBar.Create(this, IDD_DLGTREEBAR, CBRS_ALIGN_RIGHT | CBRS_ALIGN_LEFT | CBRS_GRIPPER, AFX_IDW_CONTROLBAR_LAST - 1))<br />
{<br />
TRACE0("Failed to create TreeBar\n");<br />
return -1;<br />
}<br />
m_treeBar.SetWindowText("Components");<br />
m_treeBar.EnableDocking(CBRS_ALIGN_RIGHT | CBRS_ALIGN_LEFT);<br />
Thanks

Not sure if this is related to your problem or not, but it might be.
Check this MSDN article[^]
Note this:
While it is normal to derive your own dialog classes from CDialog, you do not typically derive your own class for a dialog bar. Dialog bars are extensions to a main window and any dialog-bar control-notification messages, such as BN_CLICKED or EN_CHANGE, will be sent to the parent of the dialog bar — the main window.

Hi folks please help me. I am trying to learn how to simulate direct keyboard coding using the work of Fred Bulback from
http://www.geekhideout.com/iodll.shtml
I created a win32 console application and tried out the following codes :
PortWordOut(0x64 , 0xd2) ;
PortWordOut(0x60,18);
cin >> ch ;
cout << "ch= " << ch ;
cin.ignore(2);
PortWordOut(0x64 , 0xd2) ;
PortWordOut(0x60,19);
cin.get(nh);
cout << "nh= " << nh ;
cin.ignore(1);
//cin.get(sh) ;
PortWordOut(0x64 , 0xd2) ;
PortWordOut(0x60,20);
cin.get(sh);
cout << "sh= " << sh ;
The result is this :
both
PortWordOut(0x60,19);
and
PortWordOut(0x60,20);
are not captured by nh and sh as they are supposed to be.When i run the codes through debug i noticed that both codes which
are 'r' and 't' are produced but on the debug screen so it implies that the 2 lines of code work but output are send to the
wrong place.Incidentally the first line PortWordOut(0x60,18) works very well.
Can anybody please help explain what I did wrong and how I can get the keyboard to generate all 3 chars to the console
screen.
Regards and thanks

hello every one,
i received this morning a mail that revealed to be a CPian in a high need of help (Mr Pazzuzu[^])... saddly, i cannot help him as i don't really understand his need... (maybe i don't have enough knowledge on the related topic).
As he had some difficulties to know where to ask his question (and as i didn't wnat him to mail me for that), i created a thread on my personal homepage to let him ask.
now, if anyone have any idea about this[^], i'd be very grateful not to answer on my homepage but here, on that current thread you're reading at the moment...
thank you so much...

Could you or Mr Pazzuzu post the code for ex03aView.cpp::OnDraw?

I suspect OnPrepareDC is not being called for TemporaryDc, but it's just a hunch

sure, here it is (pssst, there's no ex03aView.cpp fil e in the project  ; i found this into pagesView.cpp) :
void CpagesView::OnDraw(CDC* pDC)
{
CpagesDoc* pDoc = GetDocument();

sizeTotal.cx = 80;
sizeTotal.cy = 80;
CRect rect;

int pageWidth = 800;
int pageHeight = 800;
int pageGap = 5;
int pageNumber =3;
SIZE size;
size.cx = 1000;
size.cy = (pageHeight*3)+100;
tempDC->Rectangle(CRect(0,0,pageWidth,pageHeight));
tempDC->TextOut(0,pageGap,"This is the first line on the FirstPage");
sizeTotal.cx *= MulDiv(m_textMetrics.tmAveCharWidth, m_iZoomFactor, 100);
sizeTotal.cy *= MulDiv(m_textMetrics.tmHeight, m_iZoomFactor, 100);
SetScrollSizes(MM_TEXT, sizeTotal);
}

Ok. He's using a class named MemDc, which I suppose is the one doing the actual no-flicker work.
Anyway, I'd just point Mr. Pazzuzu to this post[^], which might be of help, and let him post something here if he needs more help.

In the MSDN example, I can see in order to ensure only one thread access a resouce, we use:
CSingleLock singleLock(&m_CritSection);
singleLock.Lock();
// resource locked
//.usage of shared resource...
singleLock.Unlock();
However, since CCriticalSection (inheritance from CSyncObject) already have a Lock method memeber, cannt we just do?
m_CritSection.Lock();
// resource locked
//.usage of shared resource...
m_CritSection.Unlock();
Thanks!

A critical section is a nice way to control access to a section of code, not really a resource. (Unless, all access to that resources is only in that section of code)
A lock is a nice way to control accesses to an object/resource though different code paths and shared data.

CCriticalSections are usually (not always) class members or global objects that never go out of scope. So if you use CCriticalSection::Lock() you have to remember to call CCriticalSection::Unlock(). This can be tricky to implement if you code can take many divergent paths inside the lock. Using CSingleLock makes this much easier as you would normally declare the CSingleLock inside a function or loop or some other small bit of code where it goes out of scope and is destroyed when no longer needed. CSingleLock automatically unlocks the sync object from within its destructor, you do not have to explicitly call CSingleLock::Unlock().

I am using .NET with and MFC application.
I have 2 List Boxes on my main dialog. I want to change the color of just one of them to a "pink" for error state. Here is what I have so far....., but it is changing the color of both list boxes to the color.
In the constructor of my main dialog...
m_pEditBkBrush = new CBrush(RGB(255, 200, 200));
HBRUSH CPPMLAnalyzerDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
/*HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
pDC->SetBkColor(RGB(10,100,100));
// TODO: Return a different brush if the default is not desired
return hbr;*/
switch (nCtlColor) {
case CTLCOLOR_LISTBOX:
pDC->SetBkColor(RGB(100, 100, 100));
return (HBRUSH)(m_pEditBkBrush->GetSafeHandle());
default:
return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
/*pDC->SetBkColor(RGB(100, 100, 100));
return (HBRUSH)(m_pEditBkBrush->GetSafeHandle());*/
}
}
As you can see, I am trying to set the background color and then return the CBrush from before.
Not sure what I am doing wrong.
Thanks,
Josh

OnCtlColor receives a CWnd* pWnd parameter which points to the control asking for the color. You should check this parameter and only change the color when pWnd is the one you want to affect.

The OnCtlColor() method is called for every control. You need to look at the pWnd parameter. Change to something like:
case CTLCOLOR_LISTBOX:
if (pWnd == &listbox_that_i_want_to_change)
pDC->SetBkColor(RGB(100, 100, 100));
return (HBRUSH)(m_pEditBkBrush->GetSafeHandle());Another solution is to derive your own class from CListBox and do the coloring in it. Then your dialog can have one CListBox member and one CPinkListBox member.

Thank you for replying, but I have one more question...
You say if (pWind == &lisboxthatiwanttochange), but how can I compare them? Is there a member of CWnd that I can compare to the INT ID of my listbox?

goodoljosh wrote:

Exactly as I showed, except that you'd want to use the name of the member control variable and not the name I made up.

Here is what I did....
if (PWnd == &m_wndListBox) (m_wndListBox is the CListBox variable that I use to add strings to the List Box)
but it still changed both boxes to pink
|
|
|
|
|
Got it, thanks.
Here is what was happening. In the constructor, it was changing the both boxes to pink.
When I added the comparison, I didn't realize that it was there that the comparison was happening. I changed the constructor to be white, and then on the comparison, changed just the one to pink. It worked exactly like I wanted....
Thanks for everything.

Hi everyone.
im sure most of you have heard, seen or installed the Gmail drive namespace extension found at http://www.viksoe.dk/code/gmail.htm
its a great little app.
what I am trying to do is build small open source app ontop of the gmail drive which would enable a little more control when transferring files between the local drive and gmail drive. what i have in mind is a similar interface to ftp clients.
anyway at first glance i thought this would be quite easy. I am coding in visual Studio using C++ i opened a new MFC project. and implemented a new CFileDialog class this worked fine and it recognises the Gmail drive but thats as far as i can get.
theres 2 issues firstly
when i select the Gmail drive it treats it as a file not a folder(so it wont actually log onto gmail to see the files currently located on the Gmail Drive).
and 2ndly
when i look at the path returned from the CFileDialog i get ? ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\::{2B3453E4-49DF-11D
but when i try to copy a file to this location i get an error (obviosly as this is not a vaild windows file location)
(just to note if i use any win32 application and try to open or save directly to the gmail drive the same errors occur. this seems to be a common problem for all programs.)
i have never used shell namespace extensions before so am not 100% sure where to go from here.
perhaps there is a way to turn the returned string into a valid windows file location.
or is there a class already out there that works well with namespace extensions allowing files to be copied from one to another.
the unfortunate thing is i dont have the source code for the gmail drive shell extension. so until i have that this project may never get off the ground.
If any1 has any advice or ideas on how to tackle this problem im all ears.
thanks

well i have worked out the first problem of not being able to see the files this can be accomplished using SHBrowseForFolder.
and i am still working on being able to copy the files from gmail drive to HD.

Can anyone tell me what is the proper way to position a toolbar (actually a DialogBar, but the code is very similar) to the right of an existing toolbar? When I use code like:
m_slideBar.Create( this, IDD_SLIDETOOL, CBRS_TOP, IDD_SLIDETOOL );
m_slideBar.EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_slideBar);
It puts the toolbar on the top of the screen, underneath the normal toolbar.
I can use GetWindowRect(&rc1) to get it’s position, but I can’t seem to move it properly. I tried MoveWindow(rc1) but that doesn’t do the job properly. First of all, it leaves a blank “bar”, i.e. a blank space, where m_sliderBar was. Second, it doesn’t show up until I undock the first toolbar. It then appears and I can redock the first bar again.
I’m sure there must be some accepted way of doing this. I just don’t know what it is. Any help would be greatly appreciated.
Thanks,
Ilan
