CFile::GetPosition and Seek

Felagund226820-Nov-05 8:18

Something really weird is happening to me. I run the next code snippet:

<br />
int pos = File.GetPosition();<br />
File.ReadString(str1);<br />
File.Seek(pos, CFile::begin);<br />
File.ReadString(str2);<br />

str1 is different from str2 - str2 is read from a few bites earlier in the file. what's even wierder is that the difference between str1 and str2 is changing when I try this code on different locations in the file.
the file is unicode, hebrew and I'm running visual c++ 6.0, if it matters.

CStdioFile::ReadString() performs reading line-by-line (reading is stopped by the first newline character; the '\n' character is removed from the string). You do not use Seek for text files where information is stored on a line-by-line base.

Some information concerning the unicode staff in your case can be found here, at CP:

I still don't get it - if the file pointer is located at the same point in both instances, why does it matter what order do I use to read?
is there a way to 'bookmark' a location and then read using readstring? is there a way to go back in the file?

I decided to rewrite the application.
For the UI conversion there is a tool RC Convertor from www.dudelabs.com but I cannot find any other tool which can convert my business logic code from C++ to C#.Will keep you posted with my progress.

In VS .NET 2003 one used the following:

//The following #import imports the VC Code Model on it's LIBID<br />
	#import "libid:a155fa04-fade-491b-b007-fb9379ea47db" raw_interfaces_only named_guids//no_implementation<br />
	//The following #import imports the VC Project Model on it's LIBID<br />
	#import "libid:233ADBAD-405A-4249-AA0B-828093D57184" raw_interfaces_only named_guids //no_namespace<br />
	//The following #import imports the VC Project Engine on it's LIBID<br />
	#import "libid:238B5186-2429-11D7-8BF6-00B0D03DAA06" raw_interfaces_only named_guids //no_namespace

to make use of the VCCodeModel, VCProjectModel and VCProjectEngine. However when changing to VS 2005 these libids are incorrect and I can't find the corresponding ones for VS2005. Does anybody know where I can find them?

Hello
As i told in earlier post that i am using MFC to read a file from a floppy that is using linux ext2 file system. Mr. Kaken told me that i could use CreateFile(...). Does CreateFile returns an handle to inode of that file?
Thanks.

Hello again.

CreateFile returns a HANDLE (to the volume in this case). You use that handle to read from and write to the volume.
The HANDLE (AFAIK) doesn't mean anything outside Windows itself, it's just a unique identifier to use for file/stream operations.

When you open a volume, you get all the sectors of that volume as a contigous "file", kind of.

From there, it's up to you how to handle each and every sector. Just remeber, the smallest bit of information you can deal with is one sector.

Error R6029

Hi ...

I am new to VC++ though i have written a few C++ programs back in the day when u did not need a PHD in computer science to use a microsoft IDE.

Every .NET FORMS application i create using the wizard, terminates with a runtime error R6029 ... "This applicatoin cannot run using the active version of the .NET Runtime. Please contact the application's support team for more information."

That second sentence is a real laffer.

Even the simplest example in the VC++ 2003 tutorial has the same problem. It compiles and links just fine, but gives that message soon after the F5 key is struck.

I've never been a microsoft fan, and this crap just entrenches that dislike.

Any ideas or suggestions?

Thanks.

Thank you Graham ... it worked.

i had seen this b4 but i did not know how to apply it ... now i do. Besides, I culd not comprehend how THIS could apply to my shiny new VC++2003 system:

"R6027: An application built with /clr and the Visual C++ .NET 2003 (7.1) compiler is being run on a machine that only has version 3705 of the common language runtime, which is the runtime version that shipped with Visual C++ .NET 2002 (7.0)."

WHAT!!!!!

This solution raises lots of questions: Why does VC++2003 ship with the 2002 runtime library and NOT the 2003 version? Why does the 2003 compiler/linker generate code that does not run with the SHIPPED runtime?

Most important ... HOW ON EARTH WOULD ANYONE KNOW THEY SHOULD INCLUDE "/clr:initialAppDomain" TO SOLVE THE PROBLEM? Why didn't the build wizard include it if micro$oft KNEW of this ridiculous situation?

UNBELIEVABLE ... typical micro$oft ... maybe for ANOTHER TEN BILLION ...

GRRRRRRRRRRRR!

Thanks, Graham

Hi,

Capture the client area and save it.

HDC hdc = ::GetDC(hWnd);
CDC dc, memDC;
dc.Attach(hdc);
memDC.CreateCompatibleDC(&dc);
CRect rc;
::GetClientRect(hWnd, &rc);
CSize sz(rc.Width(), rc.Height());
CBitmap bm;
bm.CreateCompatibleBitmap(&dc, sz.cx, sz.cy);
CBitmap *pOldbm = memDC.SelectObject(&bm);
memDC.BitBlt(0, 0, sz.cx, sz.cy, &dc, 0, 0, SRCCOPY);

// now you can do what you need to with bm.m_hObject
memDC.SelectObject(pOldbm);
bm.Detach();
::ReleaseDC(dc.Detach());

Bye

Hello, everyone,

I want to copy a dialog from one program's resource file to
other program's resource file?
I tried , but failed.
Who can tell me the right method to do this, Thanks a lot!

Re: Ask for help: About resource file

For a conventional (not .NET) application, that uses .RC files and a resource.h file, the most reliable approach is the following:

1. Open both resource.h files in the source file editor.
2. Use the "Open With" option in the File Open command to open both .RC files in the source file editor.
3. Use copy/paste to copy the dialog from one .RC file to the other.
4. Copy the resource ID's for the dialog and its controls from one resource.h to the other.
5. Note that you may have to manually renumber the ID's for the dialog, if they conflict with other ID's already in use.

Unfortunately, I don't do .NET programming, so I don't know the procedure there.

Passing Multidimensional Vector By Reference??

I cant for the life of me figure out how to setup the syntax to get this to work, here is my vector initializations..

typedef vector<int> vInt1D;
typedef vector<vInt1D> vInt2D;

Here is how I have my function definition...

void SetupCoordinates(int, vInt2D &);

the function declaration looks like this:

void Testing::SetupCoordinates(int iUnitLength, vInt2D &Test)
{
//stuff in here
}

The compiler returns:

Error 1 error C2784: 'bool std::operator ==(const std::vector<_Ty,_Alloc> &,const std::vector<_Ty,_Alloc> &)' : could not deduce template argument for 'const std::vector<_Ty,_Alloc> &' from 'const int' c:\program files\microsoft visual studio 8\vc\include\algorithm 40

Everyone says Vectors are easy to pass to functions, but this is killing me... Thanks!!
