This thread on nehe[^] is a good start.
It's not a very easy things to do, especially if you want to make it realistic, but the basics should manageable.
Watched code never compiles.

There are a number of different options; try searching the MSDN site for possible solutions that match your requirements. Your starter for 10: Remote Desktop Connection[^].

Have you looked at NetUseAdd() or WNetAddConnection2()?

Hi,
I'm using CFileDialog to display a list of files to open, but when I change the extension type I don't get a displayed list of the newly associated files.
CFileDialog fileOpen(TRUE, "dat", "*.dat", OFN_EXPLORER | OFN_FILEMUSTEXIST, "Data Files (*.dat)|.dat|Doc Files (*.doc)|.doc|All Files (*.*)|.*||");
if(IDOK == fileOpen.DoModal())
{
....
}
It really is as simple as that, but the explorer doesnt seem to want to display the files associated with the new extensions.
Any ideas?
TIA
Tony
BTW - I'm using Visual Studio 2003 on an XP machine

I have multiple excel.exe running on my system . When I called GetActiveObject() method then I am able to get only the one excel.exe not all . So please tell me how can I get all the running excel.exe
Trioum
|
|
|
|

from what Ive seen GetActiveObject() is only going to get one instance. If you are looking for a particular instance, you could try looping :-
GetActiveObject()
Is This instance what Im looking for ?
If No CLose the excel instance
repeat until you find the excel instance you want
I was thinking that you could enumerate windows with Excel in the title, somehow close the ones you dont want (assuming you can detect the one you do want by the window title), then do a GetActiveObject()
sorry .. maybe someone else has a better idea
|
|
|
|
|
No your idea is failed every time I got the same Excel. And I cannot close the running excel.exe
Trioum

|

btw how did you implement either of my ideas ? and
trioum wrote: And I cannot close the running excel.exe
why not ? obviously if you cant close any excel instance you dont want then you'll never get to the one you do want.. what do you have so many zombie excel instances ?

I have to work with mulitple excel files not one dude

do you know if GetActiveObject() returns a reference to the Excel instance that 'has focus' or 'is currently active' ?
If that were the case, AND you could distinguish which excel instance was which by the Window title, then you could build a workable solution
a) enumerate all the excel instances and look at their window titles
b) force the instance you want (by window title) to come to the front ie give it focus
c) then do a GetActive Object
somehow I dont think its that easy - the GetActiveObject may have its own way of looking at the ROT or process table, not just the 'active excel instance' - thats confirmed by looking further : MS KB 238975 - http://support.microsoft.com/kb/238975[^]
says "NOTE: If there are multiple instances of an automation server running at the same time, the GetActiveObject() API function returns the IDispatch pointer to the instance that was first running."
So I dont think you're going to be able to do it

I Have a CString which contains port names.
CString cs = "COM1";
char portname[5];
1. What is the memory representation of cs above (I have this question since I think it is multibyte/wide char)?
2. How to copy above cs into portname ? I need portname to contain
{'C','O','M','1','\0'}
Thanks
JC

TCHAR path[ MAX_PATH ];
Cstring str;
_tcscpy(path, str);

1/
The memory representation will change depending on whether the UNICODE define is there or not. The default changes depending on which version of Visual studio you have. VS6, it's char. I think all later ones, it's w_char, or 16bits.
2/ There's a conversion to LPCTSTR operator in the CString class, so you can pass it to const TCHAR * parameters of other functions. So, your question is trivial:
lstrcpy (szBufferOut, sMyString);
Have a look at the following article for more help:
The Complete Guide to C++ Strings, Part I - Win32 Character Encodings[^]
Good luck,
Iain.

Hi,
You've got two problems here:
- Converting from potentially wide to narrow charcaters
- Getting rid of any const
The first means that you can't use something like _tcscpy and TCHARs as you want real, honest, chars, not chars or wchar_ts depending on some preprocessor macro. The second means you've got to do a real copy and you can't just use an implicit conversion.
To solve the second problem you've got to do a copy. To solve the first you either copy the string using wcstombs or strcpy depending on whether the CString is encoded as unicode as not. You can either use the preprocessor to select which function you use, but that's really sucky like most uses of the preprocessor in C++ (avoid it like the plague) or you can use function overloading:
void to_narrow( const CStringA &to_convert, char *out )
{
...
}
void to_narrow( const CStringW &to_convert, char *out )
{
...
}
I haven't bothered including the code as there's another way you can do the conversion which relies more on the C++ standard library and has less pointers flopping about and confusing the issue. In this version I'm returning a std::vector<char> as it sorts out any memory management for the caller:
std::vector<char> to_narrow( const CStringA &to_convert )
{
const char *convert_start = to_convert;
const char *convert_end = convert_start + to_convert.GetLength() + 1;
return std::vector<char>( convert_start, convert_end );
}
std::vector<char> to_narrow( const CStringW &to_convert )
{
const wchar_t *convert_start = to_convert;
std::vector<char> output( to_convert.GetLength() * 4 + 1 );
output.resize( wcstombs( &output[ 0 ], to_convert, output.size() ) );
return output;
}
The supperfluous +1s everywhere are due to CString::GetLength not including the terminating '\0' character in the length. The *4 is just in case Microsoft ever support utf-8 as a character set - it gives the oodles of space for really weird characters
Any questions just shout.
Cheers,
Ash

Hi All,
I am trying to get a splitter window for MDI when a Menu Item in Menu is clicked. The splitter window is been created but when i am trying to drag that Splitter it is not able to split also it is not performing the events of the pane. (i.e) if in Pane2 of the splitter i am having a Button Control it is not been handled.
Help me out!
Thanks,
Uday.
Here is the Code.
-----------------
void CMainFrame::OnMytreeTree()
{
CCreateContext ctx;
ctx.m_pNewViewClass = RUNTIME_CLASS(CudayView);
// GetActiveDocument() call before you destroy m_splitter.
ctx.m_pCurrentDoc = GetActiveDocument();
//ASSERT(ctx.m_pCurrentDoc!=NULL);
// m_pSplitter !=NULL when there is a visible splitter.
if (m_pSplitter)
{
// Destroy splitter window.
delete m_pSplitter;
m_pSplitter = NULL;
// Create and initialize CMyView.
SetActiveView((CView*)CreateView(&ctx));
GetActiveView()->OnInitialUpdate();
}
else
{
if(m_pSplitter == NULL)
{
//MDIGetActive()->DestroyWindow();
// Create new splitter window.
m_pSplitter = new CSplitterWnd;
if (!m_pSplitter->CreateStatic(this, 1, 2))
{
TRACE0("Can't create splitter window.\n");
return;
}
else
{
if ((!m_pSplitter->CreateView(0, 0,
RUNTIME_CLASS(CMyTreeView),
CSize(200, 0), &ctx))
||(!m_pSplitter->CreateView(0, 1,
RUNTIME_CLASS(CFirstView),
CSize(500, 0), &ctx)))
{
TRACE0("Can't create one of the splitter panes.\n");
return;
}
// Initialize the two panes (each containing a view
// associated with the current document).
((CView*)m_pSplitter->GetPane(0, 0))->OnInitialUpdate();
((CView*)m_pSplitter->GetPane(0, 1))->OnInitialUpdate();
SetActiveView((CView*)m_pSplitter->GetPane(0, 0));
}
}
}
// Redisplay frame.
RecalcLayout();
}
