Hi ...
I have asked this question but nobody answered ...
I want to call a function in the parent class of a dialog...
How to do that?
p.s
When I include parent header file in the child and child header file in header I get this error:
/////// Form1
#include "Form2.h"
Form2 ^f=gcnew Form2;
f->ShowDialog();
/////////Form2
#include "Form1.h"
Error:
syntax error : identifier 'Form2'
error C2065: 'f' : undeclared identifier
error C2065: 'Form2' : undeclared identifier
error C2227: left of '->ShowDialog' must point to class/struct/union/generic type

Is the Form2 class in a different namespace than the code throwing the errors?

Hello,
in our company we have a solution with a lot of (dynamic)ibraries which we wont use in all of our projects.
Now to use the unmanaged libraries is not a big problem. here we can use autolink to link agains the right library (debug mode and so on..).
How I can solve the problem to make a reference to the right mixed library (the designer should also work!)?
Best regards
Hansjörg

If the file you are using is a text file, then using a StreamReader may be much easier
than reading the file as an array of bytes.
If the file is binary and you're looking for embedded text, then you may have to search for the
character sequences yourself.

Huh? 
You're going to use the MFC CFile class instead of the .NET file classes?
If so, the solution is exacly the same.
The CFile class "provides unbuffered, binary disk input/output services".
So my answer would be the same - CStdioFile is probably a better choice if you're working with text
files. If the files are binary with embedded text, you'll probably need to search for the text yourself.

Hi,
I am connecting a device through GPRS, using SLIP. But that doesn't work. (if you can help here, ok) so I need to change the protocol from SLIP to PPP.
So does anybody know the bare minimum PPP protocol implementatation, bare minimum just to send and receive. In C?
Thank you very much.

You voted a one for the last reply you got in this forum so I am reluctant to offer you assistance. This forum is not for C/C++ questions. This forum is for C++ development on the .NET platform using the Microsoft CLI extensions to C++. C and C++ questions belong in the Visual C++ / MFC forum.

What does "doesn't work" mean?

Are you asking about developing your own PPP stack? I wouldn't think that has been done any longer after like Windows 95 and 2000 since the OS's provide those stacks.

Yeah I see what you mean. I did give him a second opportunity to show he isn't a giant jackass but he wasn't able to accomplish that task I see. This seems to prove, not that I needed proof, Windows isn't the only platform suffering from the attack of the monkey developers.

hehe I haven't seen enough of it yet to guess but I'm suspicious of any number of the Soapbox wack jobs we have in there. But the more obvious conclusion is that it's my charming teddy bear personality.

I suspect it involves more literacy than you seem to be bringing to the equation.

hi
how to get message from other window such as OnMessage in Mfc

In a form? If so, maybe override WndProc().

As Mark said, override WndProc() to react on specific messages. Here is a C# example:
protected override void WndProc(ref Message m) {
if (m.Msg==LPWIN_Constants.WM_HOTKEY) {
int lParam=(int)m.LParam;
if (lParam==0x00580003) Activate();
if (lParam==0x00410008) ArchiveWindow();
}

Using Events is also another option for notifying another window.
