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 Re: File Read/Write Anonymous25-Jun-03 2:34 Anonymous 25-Jun-03 2:34  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 Re: File Read/Write valikac25-Jun-03 6:16 valikac 25-Jun-03 6:16  One solution is file-mapping. Kuphryn another quesion about regular dll gucy25-Jun-03 0:19 gucy 25-Jun-03 0:19  i create a regular dll named MyDll using MFC, i want the dll popup a dialg in 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(); } who can tell me what's wrong to my program? gucy Re: another quesion about regular dll David Crow25-Jun-03 2:58 David Crow 25-Jun-03 2:58  gucy wrote: i create a regular dll named MyDll using MFC... If by "regular dll" you mean a non-MFC DLL, this is rather contradictory, don't you think? gucy wrote: who can tell me what's wrong to my program? 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.

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. Re: How to get WHOIS information in my app?

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.
