Is it possible to use RDS.Dataspace from Visual C++ to call a remote server with the http protocol. I can do this from VB, but I can't make it work from VC++.
Any comments ?

I am using WebBrowser control in VC++ project.
WebBrowser loads page form Intranet Server. I don't want to show message like "The page cannot be displayed" in case server is down. I want to show some local html page which will be stored on client computer.
Does anyone know how to catch event when page is not successfully loaded from server?
Thanks
Sanjeev.

You could try first testing the existence of the page programatically (just send a HEAD request - don't download the page). If the test succeeds, ask the web browser control to load the page. Otherwise, direct the control to a local 404 page.

if(AType == ACCESS_ALLOWED_ACE_TYPE)
AfxMessageBox("Access");
}
}
The second time when first "for" loop run unhandled error happend after this line:
GetFileSecurity( (LPCTSTR)filelist->GetNext(pos).GetString() , OWNER_SECURITY_INFORMATION | GROUP_SECURITY_INFORMATION
| DACL_SECURITY_INFORMATION , pSD , 0 , &LenNeeded );
and thats access violation...error.
Any idea?

If fileList has n positions, seems to me you're trying to obtain n+1 elements: one GetHeadPosition and n GetNexts. If the list has two elements, you'll run into an error at the second iteration.

It seems that you are right.Now how can I deal with fileLlist?

Oop,s I wasn't right, the problem is different: you're calling GetNext twice in each iteration. Do it only once, and use this reference value later:
for(...)
{
TYPE_OF_ELEMENTS_OF_FILELIST& element=filelist->GetNext(pos);
...
}

Yes,I was thinking whats wrong with my CSdtringList,I've used it many times before like this but why it does not work here.Thanks Joaquín,like always.

Are you sure GetNext() returns you a value?

Is there a way that I can read the version info in the resource and display it in the about box?

Hi all, long time no see. I have a smallish problem that I just can't get my head round. I have installed Microsofts DirectX 7 SDK and want to start using it. I have updated the lib and include directories so they look in the appropriate places (i.e. where i installed the sdk). However, when I try to use DirectDrawCreateEx() with parameter 3 as IID_IDirectDraw7 I get two unresolved externals for the function and GUID. I've had a look at the include directory of the SDK, only header files? is that normal. Is it trying to access a lib and is failing for some reason??? why? why? why? Could someone please help or point me to a page that would help me.
Much appreciated,
Alan.

Hi all, I found the problem. For anyone who has a similar problem for unresolved externals do this:
1. Make sure you have the relevant lib and include directories (where you installed SDK) listed in Tools > Options > Directories menu (and are at top).
2. Go to Project > Settings > LINK > Object/Library Modules and add ddraw.lib and dxguid.lib. (btw. Microsoft recommends you do it this way as opposed to #include headers, honest it says on their web site in the DirectX SDK section).
You'll find the errors will magically disappear if you've done it correctly.
Alan.

Me again,
Can is Automate Outlook / Outlook Express in a way that I prepare a New Message, where:
* Receiver Address
* Message Body
* Attached file(s)
is already included?
Would be nice if I can do this for Netscape etc. as well.

You can use MAPI. If you call MAPISendMail() with the MAPI_DIALOG flag set, it will display the message, ready to be sent in Outlook/Outlook Express/Whatever. I have no idea if it works for Netscape though.

Hi,
I'm looking for a C++ .lib (or sources) that can create an archive of multiple files - preferedly something that can be unpacked with winzip again.
It should be free, royalty-free, and no-strings-attached. good compression ratio is not that much an issue, but would be nice.
Data is a few text and binary files in a single folder (no subdirs (as of now)), from a few hundred bytes to usually < 2MB.
Is there anything like this?

InfoZip should do what you want. It's (obviously) based on zlib.

Crypto++ includes Gzip and Zlib support as well as a bunch of great Crypto stuff. Highly recomended.

I am trying to write a function for a CFormView called BatchPrintPage2().. the first part of this function is trying to get a handle on HDC. This is before I try to get the hDC:
DOCINFO di ;
CPrintInfo printInfo ;
CMyDoc *pDoc = (CMyDoc*)GetDocument() ;
CString filename ;
CDC dc ;
CRect draw_area ;
ASSERT_VALID(pDoc) ;
filename = pDoc->GetPathName() ; // make sure the compares will match
filename.MakeLower() ;
CPrintDialog dlg(FALSE) ;
at this point i try to get the hDC, the first way i was told to try was:
HDC hDC = dlg.CreatePrinterDC() ;
but this always returns null.
the other way i have tried is:
dlg.GetDefaults();
HDC hDC = dlg.m_pd.hDC;
this actually seems to work.. but then i get to the rest of the function..
di.cbSize = sizeof(DOCINFO) ;
di.lpszDocName = pDoc->GetPathName() ;
di.lpszOutput = filename ; // prepare the print information structure
dc.Attach(hDC) ;
printInfo.m_bDirect = TRUE ;
printInfo.m_rectDraw.left = 0 ;
printInfo.m_rectDraw.right = dc.GetDeviceCaps(HORZRES) ;
printInfo.m_rectDraw.top = 0 ;
printInfo.m_rectDraw.bottom = dc.GetDeviceCaps(VERTRES) ;
draw_area = printInfo.m_rectDraw ;
dc.StartDoc(&di) ;
OnPreparePrinting(&printInfo) ; // start printing the document
for (printInfo.m_nCurPage = 1 ; printInfo.m_nCurPage <= printInfo.GetMaxPage() ; printInfo.m_nCurPage++)
{
dc.StartPage() ;
OnPrint(&dc, &printInfo) ;
dc.EndPage() ; // reset page size as OnPrint may have modified them when header / footers were added to the page
printInfo.m_rectDraw = draw_area ;
}
OnEndPrinting(&dc, &printInfo) ;
dc.EndDoc() ;
VERIFY(dc.DeleteDC()) ;
this doesn't give any errors, but nothing prints. When tracing i see that OnDraw is called, but IsPrinting() is false. I have tried setting dc.m_bPrinting = TRUE, and this makes onDraw get called with IsPrinting() true, but it still prints nothing. My printer queue actually shows the job being sent to the printer, but when i captured the screen and look at it the 'Pages' and 'Size' columns are both blank..
also a major problem is that the 'for' loop listed above corrupts the hell out of my document.. my document file just gets destroyed with garbage from this for loop.. the dc.StartPage() sets the file to the following: (does this look like its printing to the document file somehow?)
%-12345X@PJL ENTER LANGUAGE=PCL600
*t600R&u600D*r3F&l0O&l1H&l2a8c1E*p0x0Y&l1X*b0M
*v0o0T E%-12345X
any help is much appreciated.. i can almost smell printing a bunch of views without a dialog
thanks!

Further to my reply in your other thread.
Looking at the code, if your getting a valid DC then I would expect this to work. The first things to check are that you are setting the number of pages you want to print in the views OnPreparePrinting function. For testing I would by default set this to 1.
pInfo->SetMaxPage(1) ;
You will then know exactly how many times the loop will run for. The next thing is to check for the document corruption that is happening. Put a breakpoint at the start of the for loop, and try stepping over the function in it while viewing the pDoc object in the variables/watch window. If you see any of them change (turn red), then you will see in what procedure the corruption of your doc object is happening. I would most probably think that its the CView::OnPrint() or CView::OnDraw() procedures at fault. As this code you are using is a derivative of code I used for printing documents to a PDF file (where I get a DC for a PDF printer driver), I would expect all that to work without problems.
I just noticed that there is a call to CView::OnBeginPrinting() missing just before the for loop, this is probably what will set the m_bPrinting falg for OnDraw to work correctly. It may also do some other miscellaneous stuff to avoid the corruption that is happening.
If you have further problems, post some updated code and we can go from there. It may also help to post the OnDraw() code of your view.

 woop!
the whole problem was the line:di.lpszOutput = filename; i set this equal to NULL and it actually printed all of my selected pages apparently the output was set to print to the file 'filename' which was set to my document name earlier in the code, it must be set to NULL to be 'sent to the device identified by the device context handle that was passed to the StartDoc function' (msdn).
now all i gotta do is figure out why my pages are 1/10th of the size they are when i print from the view with the print button heheh
thank you so much!

Since you are rolling your own printing, after you attach the printer DC to you CDC object you should do this:
dc.m_bPrinting = TRUE;
In case any of your drawing code is using pDC->IsPrinting(). I didn't see it in your example code.
Have fun.
