Ok in that case I'd write a custom control myself, either using win32 sdk, mfc or wtl, what you're most comfortable with. That would mean handling all the hit-testing, dragging, selections etc manually. I have once written something similar to what you want to do, using different windows for the 'items' in the view but that wasn't the right way to do it. I started redoing it by drawing directly on the custom control but I never finished that (we bought the roguewave thing).

Hi,
I'm trying to write a .NET-dll with Visual C++. Always I want to use fopen I get this error:
file error LNK2001: Nichtaufgelöstes externes Symbol "struct _iobuf * __cdecl _wfopen(unsigned short const *,unsigned short const *)" (?_wfopen@@$$J0YAPAU_iobuf@@PBG0@Z)
Does anyone know a solution? I must use fopen, because I need a FILE* for an input in an imported C-dll.
|
|
|
|
|
is _wfopen similar to fopen ???

_wfopen and fopen are the same. Only the input parameters are different.
FILE *fopen(
const char *filename,
const char *mode
);
FILE *_wfopen(
const wchar_t *filename,
const wchar_t *mode
);
I can use fopen or _wfopen. Always the compiler error occures.
Any solutions?

no, not at all...
(you certainly included the correct header file, didn't you?)

I think I have. Here my .cpp file:
#include "stdafx.h"
#include <stdio.h>
#using <mscorlib.dll>
#include "file.h"
using namespace System;
using namespace System::Runtime::InteropServices;
int file::Class1::createfile()
{
FILE* f = _wfopen(L"C:\\test.test", L"w+");
return 0;
}
And my header-file is:
#pragma once
using namespace System;
namespace file
{
public __gc class Class1
{
public :
int createfile();
};
}

Just check in the MSDN what .lib files need to be added for its linking.

Thanks for reply, but I can't extract the related information I need from MSDN. If I try to make a .NET-application using Visual C++, fopen works great. Only if I want to use that in a .NET-dll it doesn't work. Can anyone correct this code, so it will runnning as a .NET-dll, please?
My header-file:
// file.h
#pragma once
using namespace System;
namespace file
{
public __gc class Class1
{
public :
int createfile();
};
}
My implementation-file:
// file.cpp.
#include "stdafx.h"
#include <stdio.h>
#using <mscorlib.dll>
#include "file.h"
using namespace System;
int file::Class1::createfile()
{
FILE* f = fopen("C:\\test.test", "w+");
fclose(f);
return 0;
}
I'm trying and trying and get no solution. Please, it's important for me.

Hi,
i need to implement simple database function in a VC++ application,
but i cannot include any database product like Access etc.
So i need to use file-based database, are there any efficient
(fast, robust and reliable) programming technique for implementing
a simple file-based database function?
Thanks
|

|

If it is a really a simple db you can use an array of your db sets as ojects. If it is more maybe you can use the ODBC interface.
Try this @ home. (B&B)

|
|
Have a look at sqlite - http://www.hwaci.com/sw/sqlite/
|
|
|
|
|
You can use access db's without installing the Access product. All you need to install is the JET drivers (included in MDAC, which is FREE).
Alternatively, you could use your own classes and serialize them via MFC or memory-mapped files or even write a simple DBF file implementation.
onwards and upwards...

This is my quest: I open a wave in a read/write mode,I create a new file, I modify the stored data by means of special interpolation, but when I finish I'd like to have a new wave file, but how to get it in the format Wave? I mean the header (44bits)...etc

I don't really understand the question I think, but have a look at the format for wav files: http://www.technology.niagarac.on.ca/courses/comp630/WavFileFormat.html. Google is your friend.

hi
i build a setup programe for my vc++ application useing Inno programe and vcredist.exe after i extracted and also add MFC42D.DLL file from C:\\WINDOWS\system32 (XP)
when i install the program in my computer (Win XP) at home no VS installed their it work but when i tried to installed
at the computer in my company (Win 2000,Network)
it give me an error message that MFC42D.DLL cannout be found their!!!!!!!!
so why that happend ?
and how i can fixe it?

At home you must have installed Visual Studio, so the necessary files had come along with the VS and your application.
Incase of office installation that machine had no VS installed hence could not find the necessary files.
You should build ur app in Release mode to solve the problem.
If you had build the app in release mode and still the problem persisted, check while building you got a warning as ... use /NODEFAULTLIB:libname
if yes add the following line in the link tab of the project setting
/NODEFAULTLIB:mfc42d.lib in project setting at the bottom.
add for all the lib that is giveing conflict warning.
This should solve your problem,
Still Alive!!!
Thank you God.

hi all,
I am reposting the question, How do i enable/disable the menu items like File->Open ,File->Save As in Internet Explorer and other menus items.
Here is what i am going
-Get handle to IE Window
-Find the WorkerW Window
-Get the RebarWindowHandle
-Get the Toolbarwindow32 handle
After spying the IE window I come to know that MenuBars in IE window is hosted by window with a class name "ToolbarWindow32".
The problem is spy shows three ToolBarWindow32 windows all of them having the same parent window i.e "RebarWindow32".
1.How do i identify the window which host Menubars.
2.After getting the window handle is it possible to send the windows messages to the menu.
3. Is there any way of doing things in better way.
Can somebody help.
Thanks in Advance
Abhi

IE employs rebar to that extend that even the menubar is also a rebar.
