A recent rev to the C spec allows this - search for __VA_ARGS__ - but AFAIK this hasn't made it into C++ yet.
You can make an alias for a namespace, though:
namespace foo = ReallyLongHardToTypeName;

 I have a static control(derived from CStatic) and it contains two lines. I want to set the color of the first line to blue and the second line to red. Currently I am using the CDialog::OnCtlColor and using the SetTextColor function to set the color. However it sets the color for the whole static control i.e. both the lines. Can someone help?

The OnCtlColor message doesn't give you that amount of control over the text lines that gets coloured.
In cases like that where you need very flexable colour control, you might as well use the rich edit control, or search for one the various HTML-CStatic hybrids that are available on this site.

Is there a function in Win32/MFC that will determine if a file name is valid?
I'm looking for something that tests for the conditions mentioned in this article under the Naming Conventions heading.

There are probably lots of ways, but try this:
IMoniker* pMonk;
HRESULT hr = CreateFileMoniker(OLESTR("C:\\auxa.txt"), &pMonk);
if ( SUCCEEDED(hr) )
{
pMonk->Release();
}
Be sure you've called OleInitialize, CoInitialize or CoInitializeEx somewhere in your process.

Doesn't work. (they're all valid)
I went through a slew of file based functions, including things like GetShortFileName, hoping for a failure if the name was invalid, none worked.
I guess I'll just use a regular expression.

I used the following code:
--------------------------
void IsValid(LPCOLESTR pFileName)
{
IMoniker* pMonk;
HRESULT hr = CreateFileMoniker(pFileName, &pMonk);
if ( SUCCEEDED(hr) )
{
pMonk->Release();
wcout << L"'" << pFileName << L"' is valid.\n";
return;
}
wcout << L"'" << pFileName << L"' is NOT valid.\n";
}
int main(int argc, char* argv[])
{
OleInitialize(NULL);
IsValid(OLESTR("auxa.txt"));
IsValid(OLESTR("aux.txt"));
IsValid(OLESTR("aux .txt"));
IsValid(OLESTR("C:\\ filename.txt"));
IsValid(OLESTR("C:\\auxa.txt"));
IsValid(OLESTR("C:\\aux.txt"));
IsValid(OLESTR("C:\\aux .txt"));
OleUninitialize();
return 0;
}
And got this in output:
-----------------------
'auxa.txt' is valid.
'aux.txt' is valid.
'aux .txt' is valid.
'C:\filename.txt ' is valid.
'C:\auxa.txt' is valid.
'C:\aux.txt' is NOT valid.
'C:\aux .txt' is NOT valid.
Seems to work only for fully qualifed paths. Seems to fail the trailing space rule in any case.

I'm using Visual Studio 2005 to edit my icons, but I cannot figure out how to paste a 256 color image onto my 32x32x256 icon. It always comes through 16-color. Any ideas?

Hi,
At the restart of the main application, I need to reload all the child windows that were opened and visible during the previous run of the application. I used persistent frames to obtain the state of each of the child windows and write into the registry. But during application restart I need these windows to come up automatically (that is those child windows that were not closed before the main application was closed).
Its the same as saving the workspace in visual C++ and when the workspace is opened again, all the child windows would come up automatically.
Can anyone help me with this.
Thanks

hi
I need to get a list of all the computers on the LAN which are ON i.e. which are up.
For that i think the best option is to broadcast a connection request to all the systems on LAN and those who are up will be programmed to send something like their address.
I don't know how to broadcast a connection request. I have already made a client/server program in VC++, so i know the basic concepts.
If there is some material on NET, please refer.
thanx

The Q&D way is to send a broadcast PING on the network you are interested in. However, this has a few downsides.
You typically need Administrator access to send on the broadcast IP address, not all machines are required to respond to PING, and IT people tend to not like broadcast-ed traffic.
You might want to have a look at the network enumeration functions, and have a look at the "Enumerating Network Resources" sample for further options.
Peace!

I have an object of
CStringArray m_arrString.
I have to add appriximatly eight (8) thousand values with the length of max 10 characters like "ABCD-EFGD" in the m_arrString using Add menthod of array, and i will sort them.
Would the CStringArray object will work fine for 8 thousand added values,
Or is there any other to handle them ,
thanks
Regards.

normally, it should work, as the index is an int, and so can contain up to 2147483648 values.
i'd personnaly use std::vector<> but you could ask Mr ABuenger (aKa xxx'd) about his preference...

Thanks,
But will not it have any memory problems?

like what ?
of course, it's take more memory than one which contain 3 or 4 strings, but if you talk about memory leaks for example, i don't think there is problems of this order...

this is simple ...
try both ways, see how well they work, and decide yourself.
concerning memory, if you have sufficient memory on your computer there should not be any problem at all.

If you are worried about memory and know in advance how many elements you are going to add and the max size of each element, you may want to allocate a regular C array rather than using collection classes which introduce some amount of overhead.
onwards and upwards...

Then you may want to set an initial size by first calling the SetSize() method. This would allocate a large chunk of memory once, rather than a small chunk of memory 8,000 times.

Another way, which I have used, is to put the strings into large memory memory buffers one after the other (with terminating zeros between each, of course) and then store pointers to them in a CArray<>.)
