Hello,

I have a text file with the following layout.

COMMAND1
ITEM1 Value1 Value2 Value3 Valu4
ITEM2 Value1 Value2 Value3 Valu4
ITEM3 Value1 Value2 Value3 Valu4
ITEM4 Value1 Value2 Value3 Valu4
...
ITEM_N

COMMAND2
ITEM1 Value1 Value2 Value3 Valu4
ITEM2 Value1 Value2 Value3 Valu4
ITEM3 Value1 Value2 Value3 Valu4
ITEM4 Value1 Value2 Value3 Valu4
...
ITEM_N

COMMAND3
ITEM1 Value1 Value2 Value3 Valu4
ITEM2 Value1 Value2 Value3 Valu4
ITEM3 Value1 Value2 Value3 Valu4
ITEM4 Value1 Value2 Value3 Valu4
...
ITEM_N

....
COMMAND_N

In this file, I have to insert new items, or change values of items or delete existing items.

For suppose if I want to insert new item under "COMMAND1", what I am doing is, seeking the pointer to the end of "COMMAND1", writing remainig text into a temporary file, inserting my new text, then appending the text which is stored in temporary file. But I guess, it is not a best method. It takes much time every time I insert/edit text.

Is there any other alternative to do this. Can anybody tell what is the best method to do this.

Thanks & regards,
Chito

Well the assumption is rather correct but there is too many calls to the file. you should read the content of the file to the memory. Then do all the opertions (parsing, reallocation etc) and then the buffer (with the new value) should be written to the file again.

The content fo your file looks like it can be easly stored by xml. And will be easier to parse.

Have a good day

the beginning of the function CMyDllApp::InitInstance() ,just as i did in my exe. but here caused serious error in wincore.cpp (line:884)

BOOL CMyDllApp::InitInstance()

// TODO: Add your specialized code here and/or call the base class
CDlg dlg;
dlg.DoModal();

return CWinApp::InitInstance();
}

If by "regular dll" you mean a non-MFC DLL, this is rather contradictory, don't you think?

gucy wrote:

I would guess that it's too early to be calling such functions. The DLL is not fully initialized at this point, and something within CDialog requires the DLL to be up and ready to go.

One would assume you are connected with this business. You should say so or not, and don't post anonymously.

There is only one C++ product on the site, so I can't see it being very usefull to folks here at CP. The site also seems difficult to use to me at least. Confused | :confused:

How to get WHOIS information in my app?

wangdave24-Jun-03 23:48

24-Jun-03 23:48

Hi,
I want to implement a function to lookup internet IP address to get its coresponding netblock information in my developing internet app.
Perhaps,my question is how to get WHOIS information in my program. Should my app connect to WHOIS server, such as APNIC WHOIS server?

For example,
if I lookup 202.84.144.73, I want to get its information
inetnum: 202.84.128.0 - 202.84.191.255
netname: HKT,HK
... and so on.

Any ideas? Thanks in advance.

You could follow this rfc and then parse the output from the server:

If you're using MFC, use CenterWindow(CWnd::GetDesktopWindow()) in your OnInitDialog() handler.

If you're not using MFC, you'll have to do a MoveWindow() and calculate the position where it should be. Look at the source code for CWnd::CenterWindow() to get an idea on how to do this.

Dear ALL,

I am developing an application for Windows NT/2000/XP. I need to know the path of root directory in my application.

Is there any API to know the root directory path (ie. c:\winnt or c:\windows)

Thanks in advance.

Can somebody give me a simple example which does that?

How to insert a row in FlexGrid?

Radha Nair24-Jun-03 22:57

Radha Nair

24-Jun-03 22:57

My application uses a Flexgrid. Iam using the first row as the header. I need to insert new rows (data rows) after the first row (as the second row). Every new row inserted must become the second row and the remaining rows should get pushed down. Resetting the number of rows works but it appends a row at the end of the grid. Is there any way to achieve this? Where can I get the complete documentation on Flexgrid?

thanks.
