Hi,
I used next code:
<br />
if(labMask.hideemptyrows == true){<br />
mc_hideemptyrows.SetCheck(BST_CHECKED);<br />
OnCheckHideemptyrows();<br />
}
else{<br />
mc_hideemptyrows.SetCheck(BST_UNCHECKED);<br />
}
strange thing is: when labMask.hideemptyrows = true, the "else" statement is performed !!!
if I do this:
if(labMask.hideemptyrows){ ... }
then it works fine.
Can anyone tell me why this is?
tnx.
(oh btw labMask.hideemptyrows is of type bool)

What type is hideemptyrows? Using a breakpoint at the if(...) statement, what value does it have?

I had the same problem a couple of weeks ago, and finally realized that I was stepping through the code in 'Release' mode. So the values it was giving me weren't correct. You may not be doing the same thing, but just to make sure, check and see if you're in debug mode while stepping through.

Nice suggestion, but you might want to reply to V. so that he is sure to see it.

Never ever compare for equality with true or TRUE. Always do if (labMask.hideemptyrows). The reason is that, even with a bool variable, there's nothing stopping the variable from getting values other than 0 or 1. When you compare against true, the test will fail if the bool got some value other than 1.

Tnx for your reply.
However I do not agree on this one:
1. a BOOL is an "Integer", a bool a "Boolean" (true or false)
so it can't get another value then true or false. Can it?
2. even after casting (bool)labMask.hideemptyrows the if statement returned false (we saw it in the quickwatch window)
3. although I see your point (especially for BOOLs) I find it more readable to compare against true or false (you see instandly what type your variable is)
So idd if the bool class can have other values then true or false I see your point, but why use the bool and not the BOOL? (surely not memory?)
Personally I think the compiler is broken or something

..and that might just be it! I have had many a few hairy moments where the code being executed doesn't match the fragment being shown on the screen. A good cleanup and complete rebuild of the project should solve this.
If that doesn't work, then a good thumping of the PC should teach it to behave!

I'm using Chris Maunder's MFC Grid control in a personal project and I'd like to override a virtual function:
virtual void OnFixedColumnClick(CCellID& cell);
I've made a derived class and everything seems to be working right except that I want to override that function so that I can set a different compare function if the column clicked is the one that has dates in it. None of the virtual functions show up in classwizard, and I'm trying to figure out if I do it manually, how to put this in the message map so that I can get this message. I know this is something that I should know how to do, but some days I'm dumber than others. Any help is appreciated. Thanks in advance!!!

you simply redefine the method in your new class.
something like :
clas YourClass
{
...
virtual void OnFixedColumnClick(CCellID& cell);
}
...
void YourClass::OnFixedColumnClick(CCellID& cell)
{
ChrisMaunderGridBaseClass::OnFixedColumnClick(cell);
}

I got it, what you said is exactly what I was doing, which was right. Except I should have been looking for OnFixedRowClick(), not OnFixedColumnClick(). Thanks

Hi
My computer is on LAN. I know my IP address. How can I get the corresponding MAC address, to which the particular IP is bound to ? ( if I have more than one ethernet card)
I have tried Netbios, GetAdaptersInfo etc.
Is there any solution for this, something similar to GetAdaptersInfo which will work in windows NT also. ?
Thanks in advance

These are the normal solutions. Are you saying they do not work for you?

Have you tried going through the ARP table using GetIpNetTable()?

Hi,
Thankyou all..
I tried these methods..all the three, netbios, GetIpNetTable(), GetAdapterInfo().
These are the problems I am facing:-
Netbios: I am not able to find MAC if there are more than one LAN card and multiple IP set for each card.
GetIpNetTable: Doesnt give me the particular MAC address of a IP Address.
GetAdapterInfo: Not supported in Windows NT
Is there anything Like GetAdapterInfo that will work in all windows platform ?
Thanks in advance

Hi,
It's here what you need
#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];
}ASTAT, * PASTAT;
ASTAT Adapter;
void main (void)
{
NCB Ncb;
UCHAR uRetCode;
char NetName[50];
LANA_ENUM lenum;
int i;
memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBENUM;
Ncb.ncb_buffer = (UCHAR *)&lenum;
Ncb.ncb_length = sizeof(lenum);
uRetCode = Netbios( &Ncb );
printf( "The NCBENUM return code is: 0x%x \n", uRetCode );
for(i=0; i < lenum.length ;i++)
{
memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBRESET;
Ncb.ncb_lana_num = lenum.lana[i];
uRetCode = Netbios( &Ncb );
printf( "The NCBRESET on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );
memset( &Ncb, 0, sizeof (Ncb) );
Ncb.ncb_command = NCBASTAT;
Ncb.ncb_lana_num = lenum.lana[i];
strcpy((char*)Ncb.ncb_callname, "* " );
Ncb.ncb_buffer = (unsigned char *) &Adapter;
Ncb.ncb_length = sizeof(Adapter);
uRetCode = Netbios( &Ncb );
printf( "The NCBASTAT on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );
if ( uRetCode == 0 )
{
printf( "The Ethernet Number on LANA %d is: %02x%02x%02x%02x%02x%02x\n",
lenum.lana[i],
Adapter.adapt.adapter_address[0],
Adapter.adapt.adapter_address[1],
Adapter.adapt.adapter_address[2],
Adapter.adapt.adapter_address[3],
Adapter.adapt.adapter_address[4],
Adapter.adapt.adapter_address[5]);
}
}
}

I want to List all the shared folders on the computers which are connected in the LAN. We can access the shared folders through UNC naming like \\<computer name="">
I want to find all the computers inside LAN and the shared folders on them programmatically (VC++).
Thaks and Regards,
Shri

For each server, use NetShareEnum() to get shared resources.

Thanks for your help. By using NetShareEnum() I could find the shared folder on the local PC (server_name = NULL). But when I specify server_name as some other machine on LAN it says "Access is denied"
Could you please suggest me some other way of doing this?
Also I want to list all computer on the LAN. Can you please tell me how to do this? as the above fuction requires server_name and only gives shared folder names on that machine.
Thanks,
Shri

Do you have UNICODE and _UNICODE defined? What does you call to NetShareEnum() look like, including the variable types?

WNetOpenEnum() followed by WNetEnumResource(). See MSDN for examples.
