Are you seeing some relationship between the 'Map' in 'MapViewOfFile' and the 'map' in 'std::map'? Because if you are and that's why you're using std::map...well, there is no relationship between those two 'map's at all.
But that's the trouble - without telling us what you're trying to accomplish, we can't help you.

Hi,
Sorry for the improper title, which has created a lot of confusions.
I have a map of type
Std::map<string, FileInfo*> ActualMap;
Std::map<string, FileInfo*>::iterator mapIterator
Typedef std::pair <string, FileInfo*>;
The FileInfo is a class which contains the properties of the files.
I am inserting all the values properly into the ActualMap and then it has to be shared with another process in the same machine using the Named SharedMemory. So, I have implemented in following way
Std::map<string, fileinfo*=""> *pBuffer;
pBuffer = (std::map<string, fileinfo*=""> *)MapViewOfFile(hMapSharedMemory, FILE_MAP_ALL_ACCESS, 0, 0, 0);
once the above mapping of the view is done, I have inserted all the key-value from the ActualMap as
CopyMemory((PVOID) pBuf, &mapList, (mapList.size() * sizeof(std::map<string,FileInfo>)));
Now, in the client application i'm able to retireve only the size of the map but not the key-value pairs and their data.
So, please help in solving this problem.
Regards,
Mayur M

Hi,
Can someone tell me how to convert BOOL in to System::String* __gc
I'm really wired with this... 
Thanks a lot.
I appreciate your help all the time...

Please ask it in the C++/CLI forum. This is the original C++ forum.

I'm not sure I would ever ask such question, anyway, if I should, then I would ask it in the managed C++/CLI forum [^].

I'll join in the chorus of "wrong forum!".
But before you ask the question there, think about it yourself.
You have two things:
1/ A BOOL. This is a thing which has two states, true or false. 1 or 0. Orange or green. I use BOOL to represent whether something is on or off. So, it could also mean "Give Iain Money" / "Give Iain Kisses".
2/ System::String * is some weird thing from another language. But it sounds a lot like a string. (I know, I'm a genius with psychic powers). So, it would be some sort of text representation.
So, you need to understand what that BOOL represents before you can turn it into text.
Start this conversation:
CodingLover's Mum: "Darling, what does this mean when it's on?"
CodingLover: "Ah, it means __________________________"
CodingLover's Mum: "Darling, what does this mean when it's off?"
CodingLover: "Ah, it means __________________________"
But you're not done... Try this conversation also:
CodingLover's Swedish Girlfriend: "Älskling, vad innebär det när den är på gång?"
CodingLover: "Ah, it means __________________________"
CodingLover's Swedish Girlfriend: "Älskling, vad innebär det när den är avstängd?"
CodingLover: "Ah, it means __________________________"
Text is a pain - for some reason, people all over the world like to use their own language, instead of God's Good English!

Thanks for the comment. I'm not an experienced person in C/C++, and that's why I ask a question here, after different things workout.
Anyway, I'll try my best next time what you are saying in the above post.
I appreciate your help all the time...

Well, the answer to your question isn't really a "how do I write this code" answer, it's a "what does this mean / how do I represent it to the user" question, and that will be the same whether you write in VB, FORTRAN, C, ruby, etc.
In my miniscule experience, the hard questions are not coding ones, they are deciding what to code...
Good luck,
Iain

If you want to get a string value representing the BOOL, then this function ought to do you:
System::String^ GetStringFromBOOL(BOOL b)
{
return Boolean(b!=FALSE).ToString();
}
This uses C++/CLR rather than Managed C++, which is why I have System::String^ rather than System::String* (^ is a managed pointer in C++/CLR).

Thanks a lot, it works for me.

Hi
I am able to open(display) a text file using the "system" command as follows.
if(strPgmName =="FCS")
{
system("fcs.txt");
}
But along with fcs text file,even cmd.exe also is also getting opened,I dont want the cmd.exe window to get opened,so what should I do.Can anyone pls give me a suggestion.
Regards,

The system command is a nasty thing. Use ShellExecute[^] instead.
::ShellExecute(NULL, _T("open"), _T("fcs.txt"), NULL, NULL, SW_SHOW);

Hi,
I've created CCustomEdit inherited from CEdit and managed to change its background color and text color.
I'm trying to change the shape of it ( eg : on each end i plan to make it like curve a bit rather than 90 degrees )
Is there any ways to change the shape of the CEdit ? Any tutorials/sample would be highly appreciated. Can GDI able to change the style of it?
My project is MFC based.
With thanks,
KarHong

Not only edit control, but the shape of any window can be changed by setting appropriate region. In your case, create a round rect region using the CreateRoundRectRgn() function and set that region to the edit control using the SetWindowRgn() function.

Thank you very much.. I'll get back to you later after i tried your method..

what place should i place the CreateRoundRectRgn() and SetWindowRgn() ?
I've try below code but it seems like the EditBox keep on blinking
CRect rcItem;
CDC* pDC=this->GetDC();
this->GetClientRect(&rcItem);
CRgn rgn;
rgn.CreateRoundRectRgn(rcItem.left, rcItem.top, rcItem.right, rcItem.bottom, 50, 50);
SetWindowRgn( (HRGN)rgn.Detach(), TRUE );
Thanks,
KarHong

The PreSubclassWindow() function is a good place.

Why are you calling this function?
