Re: converting regular c++ to Managed C++

In 2003 last time i checked its called "use managed extensions" property.

As far as using MC++ I'm not sure what to say. MC++ is going to be outdated very soon because Microsoft is working on enhanced support for .net with C++/CLI. The syntax is very different. There are going to be a few tools to help migrate but you still need to do a code review to make sure everything is right. But of course if you really need .net support then go for MC++

DLLHOST replacement? (IIS/ISAPI/C++)

Howdy all-

I want to write a DLLHOST replacement -- an EXE that can be called by IIS to generate output...

I already have an ISAPI DLL that does this stuff, but I want to get out of that, and into a model I have more control of.

Do any of you out there know how to do this?

MDI child frame windows size

I want to change mdi child frame window size, instead of default size. I know I could change it at PreCreateWindow(). but at that time it's not known what size it should be. the size depends on view. so I change the size at view::InitialUpdate(), but it won't work.
void CMdiView::OnInitialUpdate()
{

// TODO: Add your specialized code here and/or call the base class

CChildFrame* p = (CChildFrame*)GetParent();
p->OnSize( SIZE_RESTORED, 800, 800 );
CView::OnInitialUpdate();

}
Can anybody tell me why? Confused | :confused:

Startup Location in Windows Desktop

Hello,

I'm trying to get my app to start up at location (10,10) of the Windows Desktop every time. In my current implementation, the app starts up at the Windows default location and then jumps to (10, 10)---kinda kludgy and it doesn't look good.

Is there a way to start my app in the right location without having to move it after it starts?

thanks,

JennyP

Position the app window in CmyApp::InitInstance() after the CMainFrame has been created and before ShowWindow() is called.

Thanks for the reply.

Here's the relevant code in InitInstance()...

	........<br />
        AddDocTemplate(pDocTemplate);<br />
	CCommandLineInfo cmdInfo;<br />
	ParseCommandLine(cmdInfo);<br />
	if (!ProcessShellCommand(cmdInfo))<br />
		return FALSE;<br />
        <br />
    m_pMainWnd->SetWindowPos(0,50,50,840,860,SWP_NOZORDER);<br />
<br />
	// The one and only window has been initialized, so show and update it<br />
    m_pMainWnd->ShowWindow(SW_SHOW);<br />
    m_pMainWnd->UpdateWindow();

Using the debugger, I see that the window actually paints (in the wrong place) upon the execution of ProcessShellCommand(). Hmmm.... I cannot put SetWindowPos() above this because the window (as evidenced by the errors) hasn't been created yet. Should I be intercepting another message from a process that executes inside ProcessShellCommand()?

thanks,

JennyP

CCommandLineInfo::CCommandLineInfo() inits: m_nShellCommand =FileNew
This means ProcessShellCommand() will create an emtpy new document. This maybe causing the app window to display ealier than you want. Step through ProcessShellCommand() and see what it is doing. You may wnt to overide it and do your own thing or if you don't want an new document created add:

if ( cmdInfo.m_nShellCommand == CCommandLineInfo::FileNew )
    cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;

before calling: ProcessShellCommand().

Looking at the MFC source code in your editor is worthwhile.

Multiline CListView entry (report mode)

Hello,

I need to implement a multi-line CListView report-style view and think that I'll need to override the CustomDraw message and do a bunch of item reformatting and custom drawing, but maybe there's an easier way?

Any ideas?

thanks,

boottime screen output (eg. checkdisk)

I've been reading docs for months now, and I still don't have a clue how to do it or where to get indeep information. Confused | :confused:

I'm looking for a guide howto output messages/text to screen at XP boottime for a win32 console application I wrote. The goal is to tell the user about the progress/status of the tool. I'm talking about the console-like blueisch screen that checkdisk and some 3th party defraggers use when doing stuff at boottime. Eek! | :eek:

Furthermore - since I'm guessing it'll have to be a service application - where do I start it? (from the registry, as a regular autostarting service or what?)

Anyone who can help me on this quest of knowledge could have a good chance of becomming a godlike person in my eyes Wink | ;)

... in other words: I would be more than thankfull for any info I get here! Rose | [Rose]

Thank's, but I allready tried that... it didn't do a thing, as if the app was just skipped or ignored. Guess the real question is: how do I "talk" (get a screen handle) to that blue screen?

Does this make sense?

Turtle Hand23-Dec-04 5:37

I'm trying to track down a memory leak. It was suggested that fxA() leaks. So I set a breakpoint before execution enters that function and after. When execution stops at the 1st breakpoint, I check memory for the process in Task Manager. F10, and when execution stops at the 2nd breakpoint, I again check memory. Memory is the same! This tells me that fxA() is NOT leaking.

Per Microsoft suppport, fxA() is the 4th biggest leak in the application. Are they wrong, or is this method of checking if a function leaks flawed?

This method of checking leaks is flawed. Memory is allocated in blocks of 4 or 8K. You may have allocated memory that is small enough that an entire new block was not required so you would see no apparent difference in the process' memory usage.

Turtle Hand23-Dec-04 7:28

This makes sense, a CStringArray and CArray are passed in by reference and filled in fxA(). This means fxA() uses memory and doesn't release it upon exit.

That doesn't make this function leak memory though, because it's the calling function's responsibility to release the memory of the CStringArray and CArray when those objects are out of scope.

how was fxA() suggested that it leaked ?

does fxA() allocate memory ( with new or malloc ) ?

is it the task of fxA() to also free that allocated memory ? or is it passed on to the caller or somebody else ?

if you use things like _malloc_dbg or DEBUG_NEW in visual studio, you will be able to really see where the leaked memory is really allocated.

compiler versions

Hi, sorry if this is a really dump question...
How do i check what version the compiler is?
I want to destinguish between Visual Studio .net 2002 and Visual Studio .net 2003 at compile time...
e.g.

<br />
#ifdef VS_NET_2002<br />
  do this<br />
#elif VS_NET_2003<br />
  do something slightly different<br />
#else<br />
  #error compiler not supported<br />
#endif  <br />

Thanks for any help!

Test the _MSC_VER symbol. For VC 7 it's 1300, for VC 7.1 it's 1310.

I don't know of a full list (should be findable with Google) but the value always matches the compiler version (version 1 being the first C compiler). So in VC 6, with compiler version 12.00, _MSC_VER is 1200.

Environment Variables - Scope

23-Dec-04 4:29

I have just interfaced with my first Corba Server, but the only way I can run my client application is via a batch file as lots of Environment variables need to be set up and they are setup via a batch file whitch then run my program.

So for debugging you lose the Visual Studio IDE.

Are they any way that my program can call this batch file or implement what the batch file does (adds a path to the path variable path and defines these environment variables)

I know I could define all these variable into the system (via My Computer, but they are about 50)
