Hi
i am trying to build my code and in the process of building it, I get the error "Message too long" and the build stops.
However, if I clean the build and then re-build the code this problem does not occur. I had been able to pinpoint the files, which if removed the error will not appear.
I am using the VS 2005 compiler.
I am wondering why this error appears. Please advice.
think because thats what matters

So what's the problem then? Does the compiler error reappear?

The same file is opened in 3 threads with FILE_FLAG_OVERLAPPED, then these 3 file handles associated to the same i/o completion port respectively.
In each thread, ReadFile was called in overlapped mode(the lpOverlapped parameter is not NULL).
It is strange that in WinXP, these ReadFile always return TRUE, means they complete synchronously, but in Vista, these ReadFile always return FALSE,and GetLastError returns ERROR_IO_PENDING.
Can I get these ReadFile asynchronously in XP?
Thanks

At my workplace we have an old pentium machine running dos 6.2, and we have an iomega ATAPI IDE 100mb zip drive. My boss has requested that I install it for him, which I have, however Iomega no longer offer any dos drivers for the Atapi version. We do however have a parallel port driver from an old parallel port zip drive that carked it, however we cannot get the ATAPI drive to work using this driver.
I would like to attempt programming my own driver for it and have heard of the Windows DDK - Is there a DOS equivalent? If not, how would I go about creating this driver?
EDIT: Please move to Hardware / Device Drivers.

There's next to no documentation that I could find with google.

I've got plenty of experience with C/C++, and C# on the Windows platform. I'd love to get in to doing development on Windows Mobile as well. I know you can do C# with Windows Mobile, but I'd like to learn the C/C++ side of things first so I can get familiar with the API. Does anybody know of any good resources for getting started with C/C++ on the Windows Mobile platform? I have Visual Studio 2005 Professional.
Thanks.

Hoping to rid my project of a "wait" thread with "difficult to debug" problems, I am trying to put a progress indcator in the dialog title. Any ideas?

You could maybe draw a progress bar in a WM_NCPAINT handler.

I want to install the file data.bmp in system32:
hFile = CreateFile((L"c:\\windows\\system32\\data.bmp"), GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, CREATE_ALWAYS, 0, NULL);
When I run this hFile is given a value, so I write to the file, and close it. Why doesn't it appear in system 32 ?
I have no trouble writing to other folders, but not to Windows, or even to C:.
The problem seems to be pecular to Vista, and certainly doesn't arise on XP.

As with most Vista write problems, you are probably not running the process as an Administrator. You must do so to write to any system directories.
Hope this helps,

Thanks, that has cured it. Now I have to see how to run the program in debug mode within VisualStudio, but as administrator.

I think that if you run VS as Administrator then any projects you run in debug mode under it will also run as Administrator.

I've been using C# for the last few years but now I have to work with an embedded C++ compiler and am having problems with enum types, since they can't apparently be used in a different class.
<code>
class Message
{
public:
enum Index
{
Length,ID1,ID2,ID3,Type,From,To,SourceX,SourceY,Var,Routing,MaxIndex=255
};
....
....
....
}
...
...
...
bool Sensor::SendMessage(Message msg)
{
char message[Message.MaxIndex];
message[Message.ID1] = 'X';
...
...
}
</code>
This sort of thing works fine in C# but the C++ compiler gives an error when 'Message.MaxIndex' etc is used - it says 'type names cannot be used' (or similar depending on the compiler). Do I really have to make all my enum's global (e.g. 'Message_MaxIndex') or is there a better way?

Try Message::ID1. In C++ scope resolution operator is ::.

And what does this have to do with MFC?
