Yes. They all seemed garbage values.
It also seems that some of the parametes, are passed to Associate_File() funtion, have a problem including 4th parameter which is just a string (i.e. "My own extension"). However, another string parameter "ext_ccc" have not. Because a registry key has been created with that name. I think, the problem may be in Associate_File() funtion. At first, we have to be sure for the parameter values which are passed to Associate_File() funtion.

Could you please re-post your code snippet with the latest changes that you've posted earlier?

And how do you use strings in your project ANSI or UNICODE?

ok this is the associate file function:

CComVariant Associate_File(CString Extension, CString Application, CString &Identifier, CString Description, CString Icon)<br />
{<br />
	CComVariant Associate_File;<br />

<br />
	// Close The Registry Key.<br />
	RegCloseKey((hKey));<br />

}

this is the button event:

void CForm1::OnCommand1()<br />
{<br />
	// TODO: Add your control notification handler code here<br />
	CComVariant retval;	// - "AutoDim"<br />
        CString exten="ccc_ext";<br />
	CString app_path;<br />
	CString Icon;<br />
	char buffer2[2048];<br />
	HANDLE hProcess = GetCurrentProcess();<br />
    char buffer1[2048];<br />
    DWORD r1 = GetModuleBaseName(hProcess, NULL, buffer1, 2048); <br />
    app_path=GetModuleFileName(NULL, buffer2, 2048)+"\\"+r1;<br />
    Icon=r1+"\\book.ico" ;<br />
    retval = Associate_File(".ccc", app_path,exten,"My own extension",Icon);<br />
   AfxMessageBox(("Associated the file extension .ccc with this application!"));<br />
<br />
}

maybe there is something wrong with the type conversion....right
i think iam using UNICODE

thank u

First of all, you aren't already using the functions that I've provided via my first reply in this thread.
You should find them and copy&paste to your source file before the line void CForm1::OnCommand1().

Then, replace that function with the one below.

void CForm1::OnCommand1()
{
  // TODO: Add your control notification handler code here
  CComVariant retval; // - "AutoDim"
  CString exten="ccc_ext";
  CString app_path = GetExeName();
  CString Icon = GetExeFolder() + "\\book.ico";

  retval = Associate_File(".ccc", app_path, exten, "My own extension", Icon);
  AfxMessageBox(("Associated the file extension .ccc with this application!"));
}

I didn't want to post whole Associate_File() function that might mess up the board.
So, please find and replace all commented lines below with uncommented ones in Associate_File() function.

//lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (const unsigned char*)&Identifier, lsize);
lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (LPBYTE)(LPCTSTR)Identifier, lsize);

//lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (const unsigned char*)&Description, lsize);
lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (LPBYTE)(LPCTSTR)Description, lsize);

//lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (const unsigned char*)&Icon, lsize);
lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (LPBYTE)(LPCTSTR)Icon, lsize);

//commandline = (Str(CString(char(34)))+Application+Str(CString(char(34)))+" "+Str(CString(char(34)))+"%1"+Str(CString(char(34))));
commandline = '\"' + Application + "\" \"%1\"";

//lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (const unsigned char*)&commandline, lsize);
lRtn = RegSetValueExA(hKey, "", 0, REG_SZ, (LPBYTE)(LPCTSTR)commandline, lsize);

It worked well in my system.

BTW, strings are not UNICODE.

Do you mean directory part of the fully qualified pathname?
like "C:\some.exe" or just "some.exe" for the action command.

I have a class that wraps a std::map (never mind why). To make it seamless to use I re-implement a number of the functions found on std::map, like find(), begin(), erase(), insert(), etc, and then just call the underlying map collection.

So I am working on porting this code to the Mac (which means I'm going to be pissing and moaning the rest of the day) and came across this gem:

error: conversion from 'void' to non-scalar type 'std::_Rb_tree_iterator<std::pair><const std::string,="" int=""> >' requested
</const></std::pair>

After digging and silently swearing under my breath I find that the GCC implementation of std::map::erase is different than what you find on Microsoft (note that the code worked on ALL versions of MS C++ from VC6 to VC9). Microsoft's is like this:

iterator erase( iterator i );

GCC's

void erase( iterator i );

So who's right?

Generally when I have doubts about STL I check SGL STL[^].

In this case MSDN clearly says that return type of map does not conform to the C++ standard link[^].

Grrrr why would they (MS) do that? I can see the mistakes in the VC6 version, but why keep promoting it through the other versions of the compiler???

Anyhow thanks for the info!

Saurabh.Garg26-Apr-08 9:52

26-Apr-08 9:52

Don't know my MS decided to do it this way but once C++0x is officially released MS implementation will be correct and other STL vendors will have to make the correction. In C++0x all containers erase functions should return iterator one past erased iterator n2350[^].

best book or refernce for Visual c++

peterchen27-Apr-08 0:47

because they value functionality and backwar compatibility over standard compliance?

It supposedly makes it more obvious to selectively erase items from a list while iterating through it:

for(it=cont.begin(); it!=cont.end();)
{
  if (ToUglyToKiss(*it))
    it = cont.erase(it);
  else
    ++it;
}

otherwise:

for(it=cont.begin(); it!=cont.end();)
{
  iterator cur = it;
  ++it;
  if (ToUglyToKiss(*cur))
    cont.erase(cur);
}

well, not to bad either, but I see how it can make a difference in more complex code.

If one book could take you from beginner to intermediate programmer, (in Visual C++) it would have to be Ivor Horton's "Beginning Visual C++ 6" or there are versions for VC++ 2005 and VC++ 2008.

They are all basically the same except the newer ones add some odd chapters on WinForms and a small dose of .NET for completeness.

First half of the book teaches C++, the second half is about Windows programming. MFC is the dominant class library used.

I don't think that there is single book which is the final reference of entire VC++ programming stuffs. From my experience, I recommend 4 books, by which you can pass most of the hurdles that a typical windows programmer will encounter.

1) If you are a beginner and want to learn the basics of windows programming then,
- Programming Windows by Charles Petzold - Its a classic.

2) If you want the reference for MFC, then
- Programming MFC by Jeff Prosise.

3) If you want to do some kernel stuff, then.
- Programming Applications for Microsoft Windows by Jeffrey Richter.

4) If you want a reference for debugging, then
- Debugging Applications by John Robbins.

Regards,
Jijo.

Indeed. They differs a lot.

1) Visual Studio 2005 stays more close to C++ language specifications. Where in VC 6.0 you might miss some language features. For instance try-catch block in body of constructor. I couldn't compile it in my VC 6.0 SP5.

2) But don't under-estimate VC 6.0. I've to admit that VC 6.0 is one of the best IDE that ever build. You see, still its being used by lot of companies for lot of products. Its still popular now.

3) In VC++ 2005 supports .net platform where VC++ 6.0 don't.

Have a look at Wiki[^] about the different versions of Visual C++.

Regards,
Jijo.
