What kind is mc_dirlist2?

The code should be something like this

CListBox m_DirList2

and used like

m_DirList2.AddString("test data")

Thanks for response, Michael.

I created the variable using Class Wiz.
Being confused about whether to define iit as a:
string or control

I tried both.

The corresponding .h files does indeed define
it as CListBox member.

...still stuck ..... Frown | :(

If you have your variable set a listbox then AddString should work no problem.

The only thing I noticed is that your code

<br />
mc_dirlist2[0].AddString( "test data" );<br />

is trying to access an array of ListBoxes is this correct?

a single list box would be accessed mc_dirlist2 not mc_dirlist2[0].

Can you clarify exactly how you are calling AddString

Michael,

Thanks again. I changed code per your observation to:

mc_dirlist2.AddString( "data" );

and it now compiles and runs Smile | :)

BTW:
What I am pursuing is to let the user select a file or files from his/her HD, so my next task is to find the function that reads the files and directories within a specified start directory.

I'm an old C dinosaur (mostly DOS and Unix), just getting wet with Windows and C++.

Thanks again!

Have a look at CFileDialog or if you want to do it yourself then CFileFind.

Also CListBox has the Dir() function if you do not wish to use the CFileDialog class.

Happy programming!!

template question

24-Nov-01 5:19

Does anyboday knows what is the problem here ? The follwoing source is
compiled on MSVC, but when its executed there is a "Access Violation." ?

template< typename TYPE >
class TYPEDPROPERTY;

class PROPERTY
{
public:
template< typename TYPE >
operator TYPE ( )
{
return (TYPE) 0;
};

};

template< typename TYPE >
class TYPEDPROPERTY : public PROPERTY
{
public:
TYPEDPROPERTY( const TYPE& tValue )
{
m_tValue = tValue;
}
protected:
TYPE m_tValue;
};

And the way how I use it

...
TYPEDPROPERTY< int > a( 1 );
int iA = a; // Access Violation.
...

Hi guys, I would like to create a windows and insert a Tree List. I would like that my window can attach to the main window application or to detach it and give it a Corel Draw style or something similar.
Inside this windows I would like to display a Tree list (CTreeView).
I remember that I found something here in this site but I don't remember where.
Anyway can anybody give me a suggestion?
Thank you very much.

I want my app to check if for example the windows media player is running, or MS Word, or any app!

I know this may be difficult or something like that!

I know that way to get the window of an app but then how to get the class name when you don't have it? Eek! | :eek:

I can get acces to WinAmp because they have the class name of the window on the developer section on winamp.com

HEEEEEEEELP!!!!

Use Spy++. Hit Ctrl+F, then drag the selection cursor over Word, and Spy will show the class name.

Hello, the codegurus around the world. Wink | ;)

Actually, all windows don't register the class name to OS.
Besides, if we open two same applications with the different files,
this is a different story. Cry | :((

So this depends on our desire by focusing on the class name or the window title.

Please, don't send me your email about your questions directly.
Have a nice day!

sh.hwnd = GetSafeHwnd();
sh.wFunc = FO_DELETE;
sh.pFrom = from;
sh.pTo = NULL;
sh.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
sh.hNameMappings = 0;
sh.lpszProgressTitle = NULL;

Put this line after your declaration [SHFILEOPSTRUCT sh;]

ZeroMemory(&sh, sizeof(SHFILEOPSTRUCT));

A question about Cursor???

23-Nov-01 23:52

I just tried the following out on my machine without any problems

LPCSTR buff="C:\\New Folder\\New Folder\\aaa";
SHFILEOPSTRUCT shfop;
ZeroMemory(&shfop, sizeof(SHFILEOPSTRUCT));
shfop.wFunc=FO_DELETE;
shfop.pFrom=buff;		
SHFileOperation(&shfop);

Hi,
all
Who can tell me how can I get the resource ID of the
current Cursor in my application.

Regards.

Re: A question about Cursor???

Nish Nishant23-Nov-01 22:15

Re: A question about Cursor???

23-Nov-01 22:15

GetCursor() will return the handle to the current cursor.
That should do, huh?
Why do you want the resource id?
Anyway, try using MAKEINTRESOURCE on the HCURSOR. I don't know if it will work. An HCURSOR is basically a HANDLE which is actually a void*. A void* is actually 32 bits.Thus an HCURSOR is a 32 bit number. MAKEINTRESOURCE takes a WORD as parameter and a WORD is only 16 bits. So initially I thought this would be a problem. But MAKEINTRESOURCE is defined as shown below :-
#define MAKEINTRESOURCE(i) (LPTSTR) ((DWORD) ((WORD) (i)))

As you can see the first cast is to a DWORD.
So I hope it will be okay.

But then, I might be wrong.

I wouldn't use MAKEINTRESOURCE, guys. Whilst a HCURSOR is a void *, that's not what MAKEINTRESOURCE is for. The resource management functions in Win32 take in an LPTSTR (a string). This string is the resource "name". The documentation for Win32 shows that this LPTSTR can be an actual pointer to a string name for the resource ("My New Resource"), OR, if the value of the LPTSTR only uses the lower 16 bits (ie it's a DWORD) the value represents the resource ID (IDR_MY_NEW_RESOURCE = 16000).

So, after all that the basic answer is, I don't think you can determine the resource ID from the current cursor (after all, it might be created from a resource located in a DLL, another EXE, or the system somewhere).

All Gurus:
How to convert ADO Recordset to .txt file by XML or others methods?
thanks in advance! Confused | :confused:

Iterate through the Recordset and keep writing into a flat file. You may write it as XML or as CSV.

Hi:
thanks Nish, How Can I convert xml or csv to flat file

Nish Nishant23-Nov-01 22:00

23-Nov-01 22:00

By flat file I meant a file containing records having no structured inter-relationship. Means you can't query them using SQL-like syntax. You'd need to read the records sequentially or using an index.

The advantage with an XML file is that you can use XML parsers like Expat or MSXML parser.

The advantage with a csv file is the ability to convert it into excel. I think MS has ODBC drivers for CSV files.
