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!

TCHAR from[100];
lstrcpy(from, pstr);
lstrcat(from, "\0");

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;

SHFileOperation (&sh);
}

But when I want delete folder like: "C:\\Progra~1\Netscape\\user\\someone\\cache\0" it generate a dialog error: "Can not delete file: File system error (1026)" Confused | :confused:

Put this line after your declaration [SHFILEOPSTRUCT sh;]

ZeroMemory(&sh, sizeof(SHFILEOPSTRUCT));

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

A question about Cursor???

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

Nish Nishant

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).

How to convert ADO Recordset to .txt file by XML or others methods?

Re: HELP

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

Re: HELP

Nish Nishant23-Nov-01 22:00

Nish Nishant

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.

I am not sure I understand you correctly. But if you want to send data across applications you can use WM_COPYDATA

RichEdit member variable woes

Xavier Shay23-Nov-01 18:14

Xavier Shay

23-Nov-01 18:14

In my project I've got a RichEdit box, with a mapped member variable t_Display. I've created a thread that waits for some input (in this case from a socket) and then tries to add this data to the RichEdit box. I am getting an assert error and I have no idea why. Could anyone help me? The code I'm using is thus:

char msg[MAXMSGLEN];

while (fConnected) {

sock.Recv(msg, MAXMSGLEN);
UpdateData(true);
t_Display.Format("%s%s\r\n", (LPCSTR)t_Display, msg);
UpdateData(false);

}

I assume the UpdateData() call is asserting. You can't pass or access CWnd objects between threads. You'll need to use API-level code to update the edit control from your secondary thread.
