I have a CFormView. In the lower right corner,
the user can stretch or compress the application.
How can I make the CFormView stay a fixed size
or in other words, how can I get rid of those
slanted bars in the lower right corner so that
a user can not adjust the size?
Please, any response any one can give me will be
greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

The ability to size an application is owned by the frame; your CFrameWnd class which is probably in your mainfrm.cpp file. If you override the PreCreateWindow function to look something like the following, I think you'll get what you're looking for:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style = WS_VISIBLE | WS_DLGFRAME | WS_SYSMENU | WS_MINIMIZEBOX;
return CFrameWnd::PreCreateWindow(cs);
}

The resizing is due to the frame window, the view is a child of the framewindow.
Do this :-
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
cs.style &= ~WS_THICKFRAME;
return TRUE;
}

Another solution is to handle ON_WM_GETMINMAXINFO().
-----
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO* lpMMI)
{
// TODO: Add your message handler code here and/or call default
CFrameWnd::OnGetMinMaxInfo(lpMMI);
lpMMI->ptMinTrackSize.x = ...;
lpMMI->ptMinTrackSize.y = ...;
lpMMI->ptMaxTrackSize.x = ...;
lpMMI->ptMaxTrackSize.y = ...;
}

Does anyone know how to derive a CBitmap pointer to a CImageList entry, so that an individual list entry(image) can be access and manipulated ?
Cheers.

The function CImageList::GetImageInfo(int nImage , IMAGEINFO * pImageInfo) returns the image information of image at entry number nImage into pImageInfo.
The IMAGEINFO contains a member HBITMAP hbmImage, which is the handle to the image list's HBITMAP. The image list stores all the image in a single image strip, so there is another member RECT rcImage the contains the rect of the image inside the bigger bitmap. You may attach the hbmImage in a CBitmap then manipulate it within the given rect.
I have tried it and failed, but could not identify the problem. If it failed with you, then there will be no other way (as far as I know) except to create a new CBitmap then call CImageList::Replace() passing to it the image entry and the CBitmap pointer to set a new bitmap for the entry. If you need to retreive the image at an entry you may use CImageList::DrawEx() to draw the image at certain entry on a give DC

Yes, Ive tried the same thing already and it does not work for me either.
I think that I might just cut my ImageLists up into bitmaps just to make my life more easy !
As for DrawEx .. no good .. I need to construct complex images based on multipe images... for custom dragging and dropping!! oh well

Hi. Im having a rather stupid problem:
I have a Cwnd class that has a CTypedPtrArray variable. On a handler, i want to create a Modal dialog and intialize it with some values from the CTypedPtrArray variable in the parent. After i get a valid address to the parent, i can access any variable. My problem is when i try to access the objects in the CTypedPtrArray. The address from "m_array.GetAt(i)" returns ok but the class public variables have bad pointers. Even during normal dialog execution, i cant access it, although i can access all other parent's variable, including a normal pointer to an object of the same class of the CTypedPtrArray array.
Any suggestion?
thanks in advance

How exactly are you getting a pointer to the parent? Is there any multithreading involved?

There is no multithreading, at least for now.
Im creating it like this:
CMyParent* wnd=(CMyParent *)this->GetParent();
int size=wnd->m_array.GetCount(); //<----this works well
CString str=wnd->m_array[i]->m_inner_variable; //<--bad ptr, and its valid outside it!
/////////////////////////////////////////////////
ANOTHER EXAMPLE
i have an array of CMyObject; i created in the dialog a class member CMyObject* obj;
then, when i create in the parent window
CMyDialog dlg;
dlg.obj=m_array.GetAt(i);
then when i access "obj" from the OnInitDialog funtion, it works fine!!!
The problem is that by this way, i cant add it dinamically, except if i duplicate the whole array.

This is the routine that i got a problem, it basiclly copy all files located in sPath to dPath.
The function CreateDirectory and CopyFile ar not running on windows98. I generated a log file and i discovered that on windows 98 the string dPath became invalid like:
original: "c:\teste"
garbage: "Y:\teste"
I read some articles and some of them indicate that the problem is Unicode conversion, but i try to follow the articles steps but it´s unusably.
One thing,
if in the function call CreateDirectory((LPCTSTR)dPath,NULL);
i change (LPCTSTR)dPath by a constant like "c:\\teste" the function run.
Please if you could help me, i´m thank,
LFávaro.
BOOL Cteste11Dlg::CreateTree(CString &sPath, CString &dPath)
{
CreateDirectory((LPCTSTR)dPath,NULL);
fstream f;
try
{
f.open("c:\\arq_log", ios::app);
// log para debug
// dt = _datetime_t::now();
//f << dt.fmt() << "DEBUG - Abriu arquivo de log\n";
}
catch (CFileException * pEx)
{
// log para debug
// dt = _datetime_t::now();
// f << dt.fmt() << "DEBUG - Ocorreu erro ao abrir arquivo\n";
TCHAR sz[1024];
pEx->GetErrorMessage(sz, 1024);
// log - erro gerado por excecao
// dt = _datetime_t::now();
//f << dt.fmt() << ERRO << sz;
pEx->Delete();
return FALSE;
}
f << "|" << (LPCTSTR)dPath << "|\n";
f.close();
CFileFind finder;
CString sWildCard = sPath + "\\*.*";
//CString sDestFile;
CFileFind finderDestFile;
BOOL bFound;
BOOL bWorking = finder.FindFile(sWildCard);
bFound = bWorking;
while (bWorking)
{
bWorking = finder.FindNextFile();
if (finder.IsDots())
continue;
if (finder.IsDirectory())
{
CString s = finder.GetFilePath();
CString temp=dPath+"\\"+finder.GetFileName()+"\\";
BSTR bstr2 = temp.AllocSysString();
BOOL a=CreateDirectoryW(bstr2,NULL);
DWORD d=GetLastError();
CreateTree(s,temp);
continue;
}
// copy files
if (CopyFile(finder.GetFilePath(),(dPath+"\\"+finder.GetFileName()), FALSE))
{
DWORD dwAttrs = GetFileAttributes(finder.GetFilePath());
if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))
{
SetFileAttributes((dPath+"\\"+finder.GetFileName()),
dwAttrs | FILE_ATTRIBUTE_READONLY);
}
}
/*else
{
DWORD l=GetLastError();
MessageBox("Couldn't copy file.");
} */
}
return bFound;
}

Hmmm, this looks like you are overwriting memory somewhere, a bad pointer perhaps. The problem is not with CreateDirectory or CopyFile. If you corrupt the string that you pass to those functions, then obviously they will fail. Trace through your code and try and locate when the string that you pass gets corrupted.

Hi folks..
I've created an activex control for a website that uses javascript to fetch data..
Now, the problem is that i can't manke that control DO anything even though the function is added to the project..
My question is HOW to create "PUBLIC" functions to use on my website..
This is what i'm using on the website..
<br />
<script><br />
<br />
function winamp() {<br />
<br />
myStr = MyControl.MyFunction;<br />
<br />
alert(myStr);<br />
<br />
return;<br />
}<br />
<br />
</script><br />
<br />
<br />
<OBJECT ID="MyControl" WIDTH=0 HEIGHT=0 CLASSID="CLSID:3BD88955-B9EB-4185-9F47-FEA07F6109B8"><br />
<PARAM NAME="_Version" VALUE="65536"><br />
<PARAM NAME="_ExtentX" VALUE="2646"><br />
<PARAM NAME="_ExtentY" VALUE="1323"><br />
<PARAM NAME="_StockProps" VALUE="0"><br />
</OBJECT><br />
<br />
This *SHOULD* give an alertbox - saying "Hello World".. but i get "Object not supported"
I really need some help!

In javascript, you neeed to use the parens when calling functions. Change your call to myStr = MyControl.MyFunction(); and see what happens.

Are you certain your activex control is registered on your client machines and that the users have turned all the security options dealing with unsigned controls on from within IE? Because what you've done should work; assuming your GUID is a valid control on the client PCs. If the control is proplery constructed, you should be able to reference the .object variable:
if( MyControl.object == null )
alert('Control not found');

Hello
I need a view class that can show formatted text with pictures, tables and font colors in two columns (MSWord-like with text flowing from one column to another) with page divisions.
It can be read-only, but with copy operation support.
I was adviced that I can use PDF format in some way.
Can anyone help me with at least a starting point to look for info - some MFC classes, custom controls or articles and sites in inet?
Thank you in advance

Cant you execute MSWord?

Copy and paste seems to rule out any pdf-renderer like ghostview.
Only copy may or may not work with pdf (rendering results in a graphic!)
Maybe the easiest would be generating HTML and starting an IE on it?
(You could even design your own XML-dialect and use XSLT to make HTML from it)
You have endless possibilities , but it seems what you want is a several weeks project requiring some degree of experience (or learning on the fly, extending the time).
< edit >RTF (rich text format) might help you. I am sure it can do columns, and a renderer should be somewhere in the web (OpenOffice?)< /edit >
Hope this has helped (and not shattered your dreams).
My opinions may have changed, but not the fact that I am right.

I'm trying to write a small program that shovels search parameters into Kazaa and then initiates a search. Almost a dynamic macro 
I'm fairly new with Visual Basic and C++, and I while I understand basic DLL structure, I am confused as how I can control one program through another.
Any thoughts or ideas? I know I'm missing something.
