// The pointer to my list view control.<br />
extern CListCtrl* pmyListCtrl;<br />
// The string to match.<br />
extern LPCTSTR lpszmyString;<br />
<br />
LVFINDINFO info;<br />
int nIndex;<br />
<br />
info.flags = LVFI_PARTIAL|LVFI_STRING;<br />
info.psz = lpszmyString;<br />
<br />
string lpszmyString.<br />
while ((nIndex=pmyListCtrl->FindItem(&info)) != -1)<br />
{<br />
//Found !!<br />
}<br />
<br />

But my doubt is will the above code search all the columns and rows in the listctrl, or just the 1^st column, for the lpszmyString string
?
That is I want the code to search only the first column to be searched for the string.

Thank you.

By definition, it finds items (i.e., the 1st column). Having never used it, I can't be for sure.

Question concerning IO file

Hi all,
I want to create and read/write a file. If I use fstream class, I can open only the file already exits.
If I want to create a new file. What can I do?
Thank you very much.

HI,

I did like following:

fstream *fout;
fout = new fstream("data.dat", ios::in | ios::out | ios::binary);
fout->write((const char*)name, sizeof(Names));
//Names is a struct and name is a variable of Names type
fout->close();

-----------
So what is wrong in these codes?
I run this code, no errors but the file is not created!
Thank you

I tried your code (except I did not use a pointer) and it worked as expected. Perhaps it is a permission-related issue.

As with David's comment above, but also be aware of the location that your file is being created.

tpndtbk wrote:
fout = new fstream("data.dat", ios::in | ios::out | ios::binary);

You supplied only the filename, not a definite path, which means that the file will be created in the current directory. This, in most cases, may very well be in your ..\debug\ subfolder.

HI,
THank you.
My program runs without any error but there's no file created. I think I have problem with writing permission. But I don't know how to solve it.
Can anyone help me out?

And there's a strange thing that:

If I write:

fstream *fout;
fout = new fstream("data.dat", ios::in | ios::out | ios::binary);
if (!fout->is_open())
{
cout << " can't open the file" << endl;
return 1;
}
fout->write((const char*)name, sizeof(Names));

---> the result is "can't open the file";

But if I don't check if the file is open.

fstream *fout;
fout = new fstream("data.dat", ios::in | ios::out | ios::binary);
fout->write((const char*)name, sizeof(Names));

--> there's no error but there's no file created. I think if the file doesn't exist, the instruction "fout->write((const char*)name, sizeof(Names));" should cause an error. Right?

Hi,
I'm trying to set up BlueTooth comunication between 2 devices,by using Virtual COM Port,with the RegisterDevice() function.
The problem is that the last parameter required the BD_ADDR(BlueTooth address) of the device i want to connect to.
How can i get the asddress????

Eli

First,thanx for your prompt reply.
According to MSDN:
When the client or server starts, it creates a COM port to associate
with the Bluetooth stack in the following manner:

HANDLE h = RegisterDevice (L"COM", index, L"btd.dll", (DWORD)&pp);

For the client, the Bluetooth server address (pp) is passed into the
pp.device member in the PORTEMUPortParams structure(and pp.device type is
BD_ADDR).

Anyone???

Eli.

You need to re-register the VC plugin DLL. I don't have VSS here at home so I don't have the exact DLL name, but it contains "scc" so it should be easy to find.

[edit]In VC 6 it's ssscc.dll, in VC 7 it's vsscc.dll[/edit]

Open a command prompt, cd to the directory where the DLL is, and run regsvr32 ssscc.dll

all the other exceptions that has not been catched with previous catch block. you can imagine its behavior like the default statement of a switch...
