Hello everybody in this forum.
I need to enable connection by adding my Client application and its ports in the internet connection firewall in windows xp SP1 Programmatically ?
Note:
-----
I read in MSDN articles about enabling these ports that uses networking , Programmatically in the windows xp firewall Using HNetCfg.dll found in the system32 but the problem is that:
this file in my windows xp SP1 doesn't have the FWManagerClass that was imported from the Com file ????
I really don't know why this class doesn't exist in my windows HNetCfg.dll file in system32
(i think it is applied only in SP2 . Is that right ?)
Is there any solution for doing that.

Possibly because the Firewall didn't show up until XP SP2 came out?

how can i get an output of an mainframe console?

That depends entirely upon what your using to do the terminal emulation.

Since you didn't really answer my question, I can take an educated guess and say that you don't have a terminal emulation package, library, or control, whatever...
Without that, you're not talking to the mainframe. You either need to write one, which will probably take a considerable amount of time, or you need to start searching for a terminal emulation library.

3270, 5250 Terminal Emulation packages are usually provided by IBM or similar IBM approved suppliers. VT52, VT100 from HP these days. In all cases the undertaking of writing terminal emulation is well beyond the scope of what is possible to discuss here. These days, many mainframes have a TCP/IP session if you are so lucky. Many others have a SQL or DB2 interface, at the end of the day start with your exact requirement and start you search from there.
Good Luck

If you have questions about the code the author posted, post a question in that articles message board. Go to the bottom of the article to post it.

You shouldn't have too much trouble since they're accompanied by usually excellent articles and the code should be commented. If the article is brief then it's because the code is easy to understand.

Might help a tiny bit if you give us a specific problem, the world of programming is very very very very very very large indeed.

It sounds like SQLite is a nice database for standalone applications. Is this true for C#/NET apps? There are several NET wrappers out there for the DLL. Can someone give me some advice about what works and what does not? What NET wrapper should i get? Are there any pitfalls regarding set up and use that i should be aware of when developing C# apps?

ret[i] = bLen[i];
for (int i=0; i < messageBytes.Length; i++)
ret[i+bLen.Length] = messageBytes[i];
return ret;
}
}
}
}
what is done in this code ?? it has been commented as Adding message bytes to the start of the pixels of the Bitmap.

But how do you know when the moving or resizing has finished?
I guess you should optimize your heavy painting code in the main form. You can start by enabling DoubleBuffer ControlStyles. Then optimize the paint code by only painting the invalidated portion.

hi,
i'm having error "Member not found." from the following code(in time of invoking member)..
<br />
foreach (MemberInfo mi in type.GetMember("test_mdi_Init"))<br />
{<br />
type.InvokeMember (mi.Name.ToString(), <br />
BindingFlags.Default | BindingFlags.InvokeMethod,<br />
null,<br />
ibaseObject,<br />
arguments);<br />
}<br />
what could be the problem? thanx for help

The flags of the member doesn't fit the flags that you have specified.
---
b { font-weight: normal; }
|
|
|
|
|
the member "test_mdi_Init" is a public method. also if use 'BindingFlags.Public' it throws an exception "Attemp to access a missing member". so what do you suggest?
|
|
|
|
|
BindingFlags.Default is 0, so you can remove that. I think you need BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance.
