Hello,
I create dynamic Window triggering on a mainframe event using:
CMDIChildWnd::Create(lpszHelloClass, szTitle, style, rect, parent);
As I create each new window, I want to load a dialog resource, the same resource for each new window.
How do I do this? I will be adding an ActiveX control to the dialog.
Thanks.
Jerry

You can create a CDialog derived class holding the functionality of the dialog resource. Ofcourse you should be having the resource id of the dialog at compile time itself for doing this.
After this you can use one of your events to invoke this dialog by calling CDialog -- DoModal().
You can probably refer this link to get some more ideas.

This might give you some idea.

Does anyone know of a library for loading (and possibly displaying) MS PowerPoint files? I need more control over the presentation than COM allows.

I am using a manifest to load Comctl32 v6 when the application is loaded on Windows XP. However, I get a weird paint problem when I use AppName.manifest.exe vs. when I don't use it.
http://www.sagara.org/goodbad.gif[^]
(Good == without AppName.manifest.exe; Bad == with AppName.manifest.exe)
Has anybody seen this behavior before?

Yeah, it's a known issue. I'll bet you're using VC6 ?
You need to send the toolbar a WM_NCPAINT message when it re-paints itself:
::SendMessage(m_wndToolBar.GetSafeHwnd(), WM_NCPAINT, 0, 0);

Indeed I am. Is this specific to VC6? Do you by chance have a link to a KB article?
BTW, thanks for the response.

No, I don't have a KB. I meant it was known to me. (Big whoop, says Jon.) 
No, trivial as this seems, it was one of the final straws in convincing me to upgrade to VS.NET 2003. This isn't a problem there.
If you use toolbar customization, though, this is still a problem, even in MFC ver. 7.1. They fixed the regular paint problem, but not one that occurs when the bar is resized as buttons are added or removed. Same fix applies - you just add a NCPAINT call.
You might try deriving a class from CToolbar and adding this to the WM_PAINT handler.
<edit>
Naa, forget that suggestion. You'd have to make (well, should make) the execution conditional on it running on an XP box, using themes, and all the rest of it. Nope, you're looking at just what I was looking at. Either upgrade or abandon the use of themed controls.
</edit>

I have a C# application where I want to allow runtime resizing and moving of controls. The functionality that I need is encapsulated in the C++ class CRectTracker. I need to reference the MFC library, but also provide a callable interface from C#. I have tried to create a managed C++ dll, but it does not create the linkages to the MFC library. Would it be better to create an MFC C++ dll, and then wrap the interface with managed extensions? I'm not sure how to go about the second option. How do I reference a CWnd object from C#? Any help would be appreciated.

This is a Winsock question.
I have a TCP server application that is listening for connections on port 9000. When the client application connects I do an accept(). If I look at the port number of the socket returned by accept I see a semi-random port number. My question is, can you specify what this port number will be? If I want my client port numbers to start at 9001 and go to a max of 9500, can I programatically do this? I have searched the Winsock API but I have not found an example.
Thanks

Hi, you can specify the port on the client side like this...
//set port to 5001, not set by user
sockaddr_in clientService;
clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr(HostIPAddress);
clientService.sin_port = htons(5001);//<-set IP port here
I dont know if this helps you.
Good luck.
Jerry

If I can ask -- what's your motivation for controlling the client-side port?

Hi all,
I need to have a CSplitterWnd class to be embedded in a CView class. (I know it is weird, but due to my constraints I have right now, this seems to be the only choice.) I wonder is it possible of doing this?
I try to create a CSplitterWnd with the parent MainFrame, create its own CCREATECONTEXT. It is fine up to this point. But, when I call subclassDlgItem () to make it become the child of my CFormView, the result is that the whole splitter Wnd disappear.
I wonder if anybody has done this before.
Thank you.

You can't put it in the CFrameWnd-derived class?

Seems like you are not designing the code properly, Coz if you do it will work out fine... spliterwindows needs to go into CFrameWnd derived class.

And this doesn't work? CSplitterWnd only takes a CWnd* as parent. It does not need a CFrameWnd*.
Can you further explain your design and maybe post a (stripped down!) code fragment?
I am under the impression what you want is possible, and you are maybe doing a small mistake.

We have a main project called "Alphabet". It contains three sub-projects called "A", "B", and "C".
We now have a new subproject we call "D".
The "Alphabet" project now contains a compiler definition in the project settings called "NEW_ALPHABET".
We want to compile the "Alphabet" project so that by including or omitting the "NEW_ALPHABET" definition, we can compile and link in either "B" or "D", but not both.
Can this be done, and if so, how?

Can't you use some preprocessor code in Alphabet's stdafx.h file?
Something like:
<br />
#ifdef NEW_ALPHABET<br />
<br />
#pragma comment(lib, "B.lib")<br />
<br />
#else<br />
<br />
#pragma comment(lib, "D.lib")<br />
<br />
#endif
You'll have to have the correct header files included, and have the directories where those headers and lib files live included in the project settings.

Yeah this can surely be done.
What you do you had a new project settings by Build->Configuration.
You simple need two sets of entries one that involves B and other that involves D for compilation and linking.
Do the appropriate changes in the project setting to link the proper libraries... And also set the appropriate dependancies.
this way you will ignore the build of the project that is needed and plus you will not have any confusion during each build on which lib file was linked.

new to makefiles.
Heres my problem:
I used an xstring (custom) object in a class myClass, which has a functionality test fMyClass. In the makefile I did:
fMyClass.x: $(proj)/fMyClass.o myclass.o
$(CC) -o fMyClass.x fMyClass.o myclass.o
fMyClass.o: $(proj)/fMyClass.cpp
$(CC) -c $(incpath) $(proj)/fMyClass.cpp
myClass.o: $(proj)/myclass.h $(proj)/myclass.cpp $(cpp)/xstring.h $(cpp)/xstring.cpp
$(CC) -c $(incpath) $(proj)/myclass.cpp $(cpp)/xstring.cpp
and it gives me errors like:
Undefined first referenced
symbol in file
operator<<(ostream &, XString const &)myclass.o
XString::~XString(void) myclass.o
XString::XString(char const *) myclass.o
I do have xstring.h included in myclass.cpp.
What do I need to fix here? The fMyclass doesnt use xstring, but myclass does.
thanks,
ns

Hi ns,
Don't you need also to include an additional xstring.o entry and add it to fMyClass.x?

Thats exactly it!! I had been trying different places to put in the xstring.o but it didnt occur to me to add it to the fMyClass.x line as well. Many many thanks!

Can some one tell me, How do I pass Typdef name which is stored in string variable to be passed to as a functions parameter.
For eg: LOOKUP_CODE (which is a typedef for struct)
LOOKUP_CODE MYCODE[]=
{
{0, _T("1234")},
{1, _T{"3455")},
{NULL ,NULL}
}
I use to call my function, which takes the first parameter of LOOKUP_CODE
MyFunction(MYCODE,....) This works like charm.
Now I'm storing that name MYCODE into string variable strCode
LOOKUP_DEF Class = reinterpret_cast<lookup_def &="">(strCode);
and calling the function like this:
MyFunction(&Class,...) but it does not work correctly. Any input from any one is greatly appreciated.

I really cannot make sense of what you're trying to do. Maybe you could post some more code illustrating your problem?

How would I pass the name of typedef which is stored in string variable as a parameter to an function which accepts the typedef data type?
For Example:
Name of the typedef is CODE, so the function will be called like this MyFunction(CODE).
What I'm trying to do is store the typedef name in string variable StrCode then call MyFunction((Type cast) strCode).
Question is how do I type cast the string variable to typedef in this suitation, I tried using reinterpret_cast, but it did not work.
