I have added a new ATL class in the project but now I want to remove this class from the project. How can I remove the class because If I remove the class manually then i need to remove other settings of the class also as it is an ATL class so it must be having enteries in the coclasses of the project.
Thanks in advance for ur help

Hm, not so easy work.
1st - remove the class .h and .cpp files (and delete/rename on HDD)
Then you'll have probably corresponding .rgs file in the project tree.
Then you need to remove corresponding parts in the projects .idl file - these should be probably the interface declaration IYourClass somewhere on the beginning of the .idl file. Then remove the coclass definition from .idl (should be somewhere at the end of the file).
Then last thing should be the OBJECT_ENTRY macro in the yourProject.cpp file.
Then rebuild the project and compiler will remind you about missed includes or macros.

Yes, u r right
I had to remove entries from the idl file also.
Thanks

Hi,
I'm not sure but i think that removing "class.h" and "class.cpp" files from the project will do the job.

I'm not exactly sure what you are asking, but does AssocQueryString() or FindExecutable() help?

Hi All,
I' m writing a Visual C++ MFC dialog-based program. I added a Menu bar uisng Insert->Resource-> Menu, not by writing code. Then, I tried to show and hide the Menu bar of a modal dialog dynamically but didn't succeed? Could anyone kindly help me?
Cheers,

I don't know any direct command that show/hide menu but the following will work too.
For removing menu bar at run time use following code
CWnd* pMain = AfxGetMainWnd();
if (pMain != NULL)
{
CMenu* pMenu = pMain->GetMenu();
while(pMenu != NULL && pMenu->GetMenuItemCount() > 0)
{
pMenu->DeleteMenu(0, MF_BYPOSITION);
pMain->DrawMenuBar();
}
}
For adding menu items again, use
AppendMenu

Hi Freind,
Thanks. But I only successfully hide the Menu, but not showing it again. Do I just need to replace "pMenu->DeleteMenu(0, MF_BYPOSITION);" to
"pMenu->AppendMenu(0, MF_BYPOSITION);" without changing other code?
Cheers

Can anyone help me find three different C++ statements for a source code that will print out the ASCII value of a character and only the ASCII value?
Thank you
|
|
|
|

#1
for(int i=65;<120;i++)
printf("\nASCII of %c is %d",i,i);
#2#3

There are 256 values in the ASCII table. If you are only wanting to print out the ASCII value, then you simply need to print out the numbers 0 through 255.
for (int x = 0; x < 256; x++)
cout << x << endl;It would be a little more useful if you printed out the ASCII character and its value:
for (int x = 0; x < 256; x++)
cout << (char) x << " = " << x << endl;

Another option:
#include <iostream><br />
<br />
using std::cout;<br />
using std::endl;<br />
<br />
int main() {<br />
<br />
char character = 'A';<br />
cout << character << " " << (int) character << endl;<br />
<br />
return 0;<br />
}

I need help to make a simple application using Embedded Visual c++ 3.0
It's just a simple application that enables me to read and write files.
Write a file - save it - then retrieve it within the application.
Can anyone help to give me the codes needed for me to make the application work?? Thanks.

Using MFC. I need to do a simple Open/Save Dialog application. I'm a beginner and i ain't sure how to link the menu to the dialog.
Help please! Thanks.

Ok, then you should check out the CFile and CStdioFile classes. They allow you to read from and write to a file.

See if the CFileDialog class is what you are after.

What menu? While they can co-exist, menus and dialogs are not necessarily related.

I have to make a mobile IP client. I understand the principles but I don't know how to implement it.
What I need to do is getting any packet passed to network layer from link-layer, then processing them before passing them to network-layer. But I don't know how to get those frames.
One friend told me that I have to hook some Windows API, which are used for processing link-layer's frames, another told me that perhaps data from link-layer is put in a buffer.
Any one can help me?. Please give me advises or ideas.
Thank you very much!

I think, if you'll search the MSDN or google for NDIS.
These drivers sits between the TCP and link-layer, so it should be suitable for your needs.

Thank you geo_m.
After posting the question, I found that Visual Studio provides Filter-Hook driver and Firewall-Hook driver
These drivers are provided with the same purpose of NDIS. But I don't know what is the best one to use in this case.
How about system-suplied IP filter driver? I heard about it but I don't know whether we can use it or not.

Yes, first I looked also for he firewall-hook, but it states in documentation that
It is not recommended to implement a firewall-hook driver (or firewall driver) for Microsoft® Windows® XP and later versions of the operating system
With filter-hook, it seems better for me, but the documenatation I have is still marked as preliminary, and there is no statement about supported operating systems (if important)
Personally I would go to NDIS driver, as it is a proven solution and you can probably find more samples.
System-supplied ip filter driver - didn't heared about.
One warning - if it somehow transfer the data from driver to user mode process, it can kill the overal performance of the network on the machine, as switching from user mode to kernel mode and back is quite expensive operation. So consider carefully which method is best for use also with calculations of the expected data flow.

Thank you geo_m!
Now I'm implementing using NDIS. However. What I need is an IP packet that has been added an Ethernet header. But I in a source code example I saw that what we get in the function MPSendPackets() is a packet which is added an Ethernet header.
What should I do now?
|
|
|
|

I'm not sure, that I understood the question. Can you rephrase it somehow?
Just meanwhile, you can check FAQ and related stuff @ www.ndis.com[^]

I will explain more.
To build a mobile IP node, I have to tunell an IP packet. That means I have to add a new IP header before the original IP packet. It is called encapsulating. When the receiver gets the encapsulated packet, it will decapsulate to get the original IP packet. See the picture below
The original IP packet:
--------------------------------------------------------------------------
| Extra info | source IP addr | dest IP addr | Data
--------------------------------------------------------------------------
After encapsulating:
--------------------------------------------------------------------------
| New ex-info | New source addr | New dest addr | Extra infor | source IP..
--------------------------------------------------------------------------
\_________________________________________/ \_____________________________

New IP header Original IP packet
That is why I need to get the IP packets and encapsulate them before transfer to higher or lower layer.
However, when I read an example source code in the article "NDIS Packet Alteration/Encapsulation Techniques" from http://www.ndis.com/code_snippets/default.html. I see that what the we can get in MPSendPacket is an Ethernet Frame (an IP packet which is added an Ethernet header). So I don't know how to add a new IP header in this case.
Do we have another way to get IP packets without Ethernet header?
|
|
|
|

Hm, I think, this is because NDIS sits between ethernet-layer2 and IP. Therefore you need to handle it somehow.
I downloaded the sample you mentioned - this is a sample of VPN tunnel - this is done on the ethernet level, so whole ethernet packet is encapsulated.
What I think you have to do is remove the ethernet frame from the packet, construct new ipinip packet and add an ethernet header again.
Don't know another place, where you can get & modify IP packets.
