The same way as when doing any other drawing, select the font you want into the device context.

How To create a window in MFC dynamically

My class uses mathematic operation (time critical) and i want the window with progress bar appear, but i couldn't create a dynamic window, i tried this:

CWnd * pWnd = new CWnd;
pWnd->Create("asdf","asdf");
pWnd->ShowWindow(SW_SHOW);

But it doesn't work.
And another question = how to create a dialog window dynamically without using the resources?

is there a particular reason why you don't want to use the resources ? I would make your life simpler ...

BTW, you can't create a dialog by just using CWnd.

you need to create a DLGTEMPLATE and call InitModalIndirect ...

like this:

Is there some kind of heap limit of DLL

I'm writing a (COM-based) toolbar for IE. At some point I found "new" returned NULL whenever the data size became larger than 300K.

Then I tried ::HeapCreate to create a heap of initial size 1M, but when I used ::HeapAlloc to allocate a chunk of 500K, it said "not enough quota". (It works when the size is 300K, though)

Then I used IMalloc::Alloc to allocate memory, and allocating 1M memory succeeded.

I'm totally puzzled why new and HeapCreate failed and IMalloc would succeeded. Is there some kind of limit on the memory size of a DLL(as my toolbar is compiled into a DLL which is loaded by IE)?
Anybody has any idea?
Thanks a lot.

How to save a playlist

I am trying to design an mp3 player similar to winamp but I want some ideas on how should I save the location of every name of mp3 or audio file in the list.
I mean how do you think winamp stores it's list with music. Is it making a temporary file with all the files exactly e=when they are added and then if you double click a certain item in the list it serches for the text in the file and then the next line is the path . . . Can you please give me some ideas on how can i save the paths for the mp3-s of the list after it is loaded because I don't want the mp3-s to be stred in the list full path becasue they look horible.
Thank you.

WinAmp saves its playlist like an XML file. Just open the winamp's playlist in Visual Studio and you will exactly see the format.

Hope this helps.

converting regular c++ to Managed C++

How can I convert all my regular c++ code to MC++?
I searched in Microsoft.com and found the following link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmex/html/vcconaddingmctoexistingapplication.asp[^]

But I couldnt' even find Compile As Managed property in C\C++.
Is there anyway to convert it without recreating new project, then adding back one dialog by one dialog and then one function by one function?

Thanks

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

23-Dec-04 8:20

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

23-Dec-04 8:12

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?

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]
