My GetActiveView is returniung a null pointer. Maybe thius is because I dont have an active view? When I run the app, it pops up with one CFormView in it which I was assuming is the so called active view> Am I right? Or do I have to do something to make a view active?
Appreciate your help,

I had a way of getting the pView pointer but its not working anymore. I posted on anotehr thread. What I would like is to get a fresh sample or pointer on how to get to the view class members from the mainframe. Its a CFormView based MDI project with only 1 doc and only 1 view at this stage.....

I would like to draw some text then outline it with a black border. How does one do something like this?

use GetTextExtent or DrawTextEx with the DT_CALCRECT flag to find the size of the text. then draw a rect of the appropriate size at the appropriate place. that's a rectangular border.
if you actually want an outline around the individual characters (like you might find in a graphics package), then you're in for some work. one way is to draw it slightly larger in black, then draw normal size on top - one character at a time. or, you could draw the text, use some kind of filter to detect the border, overlay the images, etc..

Could I draw the whole string slightly larger than one I overlay or do I have to do the characters one at a time?
Cheers,
Clint

if you draw the whole string, you could run into alignment problems, since the spacing between characters may be different between the two font sizes. but, it might be worth a shot.

One fairly easy solution is just to draw your text 4 times in black, offset by one pixel in each direction, then once in your desired colour in the middle
i.e.
Text( x-1,y, "Hello", BLACK )
Text( x+1,y, "Hello", BLACK )
Text( x,y-1, "Hello", BLACK )
Text( x,y+1, "Hello", BLACK )
Text( x,y, "Hello", WHITE )
or you could just use a for loop if you want a thicker border
Obviously this all relies on your text rendering code being nice and fast, but if you're using anything modern then it should be

I'm working in C and would like to be able to use the SHBrowseForFolder to have a folder browser. I used the following code:
void FolderDialog(HWND hDlg, int msgField)
{
IMalloc * pMalloc;
if ( SHGetMalloc(&pMalloc) == NOERROR )
{
BROWSEINFO bi;
char pszBuffer[MAX_PATH];
LPITEMIDLIST pidl;
bi.hwndOwner = hDlg;
bi.pidlRoot = NULL;
bi.pszDisplayName = pszBuffer;
bi.lpszTitle = "Select Directory";
bi.ulFlags = BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS;
bi.lpfn = NULL;
bi.lParam = 0;
if ((pidl = SHBrowseForFolder(&bi)) != NULL)
{
if (SHGetPathFromIDList(pidl, pszBuffer))
{
SetDlgItemText(hDlg, msgField, pszBuffer);
}
pMalloc->Free(pidl);
}
pMalloc->Release();
}
}
I get the following two errors:
error C2039: 'Free' : is not a member of 'IMalloc'
(846) : see declaration of 'IMalloc'
error C2039: 'Release' : is not a member of 'IMalloc'
(846) : see declaration of 'IMalloc'
If I remove the Free and Release statements the program execute fine but I would rather not have that kinda leakage going on. Any suggestions would be much appreciated.
Thanks

Use the vtable explicitly.
pMalloc->lpVtbl->Free()

Stefan,
I did something similar earlier but now I get the following errors:
error C2198: 'function through pointer' : too few actual parameters
error C2198: 'function through pointer' : too few actual parameters
Believe me I would have much rather done this in civilized code but its not my call.
Thanks

Ok Stefan,
You were right, sorry about the hassle. I found the explanation to my question here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/directx9_c/directx/intro/program/com/usingc.asp
Should have researched more before I opened my mouth.
Basically using COM with C requires an extra level of indirection + an additional parameter which points to the interface...
so in my case, this works:
pMalloc->lpVtbl->Free(pMalloc,pidl);
}
pMalloc->lpVtbl->Release(pMalloc);
Thank you much

THis is an MFC MDI app. I get the msgBox for :
CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame();
CResizeSonarViewBoxView *pView = (CResizeSonarViewBoxView *) pChild->GetActiveView();
if(pView == NULL)<code>AfxMessageBox("Null pView")</code>;
I only have the one view so far. Whats is wrong and how do I fix it?
ACtually how do I go about tracking down this problem?
Thanks

Hello,
For MDI you have to do it another way....
<br />
CView * SomeClass::GetActiveView(void)<br />
{<br />
POSITION pos;<br />
CMDIChildWnd *pChild;<br />
CDocument *pDoc;<br />
CView* pView;<br />
CMainFrame *pFrame;<br />
<br />
pFrame = (CMainFrame *) AfxGetMainWnd();<br />
ASSERT(pFrame!=NULL);<br />
pChild = pFrame->MDIGetActive();<br />
ASSERT(pChild != NULL);<br />
pDoc = pChild->GetActiveDocument();<br />
ASSERT(pDoc != NULL);<br />
pos = pDoc->GetFirstViewPosition();<br />
ASSERT(pos != NULL);<br />
pView = pDoc->GetNextView(pos); <br />
return pView;<br />
}<br />
Hope that helps,
Paul...

I see what you are doing. But the sample I have trouble withis actually from a working program that I put together last year..............it works great there! I wonder why.
I'll do your method in this project though I am very very puzzled!

The one thing that might be the problem is that my old project where the code I posted, has two views. In this curent code I only have 1 view.....Could that be the problem?

Crashed at the assert:
POSITION pos;
CMDIChildWnd *pChild;
CDocument *pDoc;
CResizeSonarViewBoxView* pView;
CMainFrame *pFrame;
pFrame = (CMainFrame *) AfxGetMainWnd();
ASSERT(pFrame!=NULL);
pChild = pFrame->MDIGetActive();
<code>ASSERT</code>(pChild != NULL);

Hi all,
I've written a function that finds the top window, botttom window, and next highest window (in terms of z-order). It then takes the top window, places it behind the bottom window, and make the next highest active. This works for everything except MS Office windows. For some reason, MS Office apps always end up being placed behind the next highest window, which means when cycling through the windows, they show up as evey other window.
I'm using GetWindow in a loop in the function, and according the MSDN, it recommends using EnumChildWindows instead of GetWindow in a loop. Is there a function that I can use in the EnumChildProc that will return a value for the z-order of the window (or is there a better way to do this)?
Thanx!
Chris

Hello,
Just wondering if anyone has any neat tricks to give users an option to have your software startup when windows loads (or not startup)..
Any ideas?

We have a rather large touch panel interface design application that was not originally designed for or compiled with the _UNICODE compiler flag. We have need now to be able to accept Unicode character input (either via foreign keyboard/OS, or by IME, or by clipboard) in a single specific edit control (which is currently a CEdit object).
I've done considerable amounts of research and testing into overriding window procs and message pumps in an attempt to receive WM_CHAR messages as Unicode character codes, but have not achieved 100% success (i.e., some characters come though as Unicode, but others still come through as the familiar '?'/0x3F character).
Any insight or tips & tricks to pull this off would be greatly appreciated, as we are willing to try just about anything to avoid having to recompile as a Unicode application and deal with the time and headaches involved with the conversion and with linking with external LIBs and DLLs.
As always, thanks in advance.

I want to embed the WebBrowser control in my application, and I want to add custom protocol handling. I figured I just host the protocol handler in my application and register it on app-startup.
However, it looks like the protocol registration is global, and hence any other running instance of IE open while my application is open will use the same handler.
Is there some way to register handlers for a specific instance of the browser? Or do I just get to put up with this "added feature"?
