Hello!
I have two classes. In class 2, there ist a function call OnWriteStuff
Now i want to call that function which is in class 2 from class one. Take a look:
void CSampleView::OnDoWork()
{
CSampleDoc* pDoc = GetDocument();
POSITION pos = pDoc->GetFirstViewPosition();
while (pos != NULL)
{
CView* pNextView = pDoc->GetNextView(pos);
if(pNextView->GetRuntimeClass() == RUNTIME_CLASS(CVorschauView))
((CVorschauView*)pNextView)->OnWriteStuff();
}
}
but, it dont work, why?! How can I solve this?
thx in advance

Without telling us what problem/error you are seeing, a guess is the best you could hope for.

he don't call the function OnWriteStuff().
Maybe I'm on the wrong way. Can anybody tell me, how i can call a function, which is in an other view?!

How do you know? Have you set a breakpoint and stepped through the code one statement at a time?

in the other View where OnWriteStuff is.
I Also put there a MessageBox in it, if OnWorkStuff is calling, the MessageBox should appear. But the MessageBox didnt apear
can ya help me david?!

It does not make sense to put a breakpoint within the OnWriteStuff() itself when it apparently is not getting called. Go further upstream and put the breakpoint at/near the various places that OnWriteStuff() could get called. You should then be able to ascertain what conditions are failing that keep OnWriteStuff() from being called.

you re right. I solved the problem 
thx for that, but I have now an other problem.
in the OnWriteStuff() function, i call Navigate2(). The second class is a htmlview class. And normally, it must work, but it doesnt, why?!
ist shows me only that:
ASSERT(m_pBrowserApp != NULL);
where is my mistake?!
sorry for that damn poor english, i m from lettland

I've only used CHtmlView once. My usage of Navigate2() looked like:
Navigate2(_T("C:\\Winnt\\Temp\\Gymnast.html"), navNoHistory, NULL);

This simple class gives a compiler error under Microsoft Visual C++ .NET (7.1.3088) ...
error C2653: 'n1System' : is not a class or namespace name
error C2143: syntax error : missing ',' before '*'
#pragma once
#using <mscorlib.dll>
using namespace System;
__gc class test
{
public:
__delegate int MyDelegate(String *str, Int32 *n1, Int32 *n2);
test(void);
~test(void);
};
but compiles fine with only one Int32 declared in the _delegate
__delegate int MyDelegate(String *str, Int32 *n1);
Any ideas?

MSDN[^] says that the declaration of the Delegate should be outside the class? anything to do with that, coz i have no idea about VC.net

No I don't try this, but you gave me the clue to my problem. I must try to transform a Cbutton and not a static. Thanks a lot. I'll need it in a bigger context so "transformation" is necessary. Now it works perfectly.

Does anyone know how to programmaticaly get IP address of network printers ? For the moment, the only solution I got is to get them when the port is given this way : IP_XXX.XXX.XXX.XXX. But in the other cases, is it possible to retrieve this IP address ?
Best regards
Sylvaine

If you know the name of the printer, can you use gethostbyname()?

The problem is that I only know the share name of the printer that is not always the netbios name.

Could anyone tell me how to create a group box at runtime or modifying an existing CStatic member to a group box. I tried to create a group box and a static on a dialog. Now I used m_CtrlGroupBox.GetExStyle and GetStyle.
These gotten styles I set to the static member via
m_CtrlStatic.ModifyStyleEx(0,GroupBoxExStyle);
m_ControlList[Zeile]->ModifyStyle(0,GroupBoxStyle).
Static doesn't "transform" to group box. I saw a black border around now and label text in this border. Does anybody know how to do it?
Thanks

Have you tried:
CreateWindow("BUTTON", ..., BS_GROUPBOX, ...);

Hi All,
I converted a dll to support unicode (by defining _UNICODE, UNICODE flags; using TCHAR , etc.). Now it is not getting registered saying 'LoadLibrary("x:\xyz\FileName.dll") Failed - the specified procedure could not be found'
Please help...

What about:
LoadLibrary(L"x:\\xyz\\FileName.dll");

I'm working on a .NET C# application which calls an unmanaged DLL (written in C/C++) which interfaces with a 1553 network to read and send data to a 1553 bus controller. This means that my application is hard to test on my regular desktop since it doesn't have the needed network hardware to actually send or receive data. Furthermore even if it had the hardware, setting up a test with the appropriate network traffic is very difficult (though we do have specialized lab facilities that can do it -- heavily scheduled facilities). My objective is to run complex, challenging, realistic tests of my application on my desktop.
My thought was to create an unmanaged DLL in .NET which could "pretend" to be the network DLL and feed data to my application in the same way the real DLL would. This sounds good in principle but I haven't quite managed it yet. With some help from the internet newsgroup, I managed to create a VC++ unmanaged DLL which when created looks like the network DLL to my application. David Browne on microsoft.public.dotnet.languages.csharp provided the following instructions for me:
Visual Studio > New Project > Visual C++ Projects > Win32 Projects > Win32
Project
Brings up the "Win32 Application Wizard"
Change Application Settings > Application Type
Choose ApplicationType: DLL and Additional Options: Export Symbols
That will create a skeleton of an unmanaged DLL. In the [appname].h file
are the exports for the application, with examples of exporting a class,
variable and a function.
This actually worked great. Now however, what I'm trying to do is to do something useful within that C++ unmanaged library.
There are no doubt many approaches that could be used for this. One might be to have the unmanaged DLL read a file that contains a "scenario" of network messages. Unfortunately, the usual XML processing classes don't seem to be available, probably because they are "managed" and available only through the CLR. The question is what to do about that? I get the hint from reading some of these postings that I might be able to eventually overcome that limitation by creating some C# app doing what I need and calling it from the C++ but that seems complicated. Is there a better way to read this scenario file? Am I better off just reading it as text and doing my own parsing? I'm pretty new to the sophisticated parts of .NET so I thought I'd ask for some advice. Thanks.
