Carlos Antollini24-Oct-01 9:33 Carlos Antollini 24-Oct-01 9:33  Dear Hadi I will answer yur questions. A1. Initial Catalog is the database in wich you connection will do the pointer. For example if you Use Initial catalog= db1 over SQL Server your connection will open the db1 database.... A2.CursorLocation: This property allows to select between cursor libraries accessible to the provider. Usually, you can choose between using a client-side cursor library or one that is located on the server. Best Regards..... Chau!!! Carlos Antollini. Re: Two questions about ADO ... Hadi Rezaee24-Oct-01 10:21 Hadi Rezaee 24-Oct-01 10:21  Hi Mr.Carlos, thanks alot for your answers, Reply A1: hmmm, so i must write my database name in Initial Catalog, so what i'll should write in Data Source ? Can i write only Provider and Data Source in the connection string for connecting to SQL Server database ? Reply A2: When my database is Access, then i can use of CursorLocation ? If my database is SQL Server, then can i use CursorLocation ? New Q: What is difference between thease Providers: SQLOLEDB and MSDASQL ??? New Q: Question is about CursorType: When my database is Access, i must use adOpenKeysey instead adOpenDynamic ? why ? If my database is SQL Server, can i use adOpenDynamic ?

Carlos Antollini24-Oct-01 11:07 Carlos Antollini 24-Oct-01 11:07  Dear Hadi. let me see... A to Re:A1: Is true you can write the connection string without the Initial Catalog, but you need to selecting the default database in the ODBC driver configuration. A to Re:A2: When you use a access databaase you only can use the adUseClient Cursor Location or adUseNone. Obviously, in this case, that you will use the first option... A to New Q: I will copy directly from the MSDN the following: Microsoft OLE DB Provider for SQL Server (SQLOLEDB), which directly maps OLE DB interfaces and methods over SQL Server data sources. Microsoft OLE DB Provider for ODBC (MSDASQL), which maps OLE DB interfaces and methods to ODBC APIs. OLE DB consumers connect to a SQL Server database through an existing SQL Server ODBC driver. We recommend using SQLOLEDB, supplied with SQL Server, as your OLE DB provider. SQLOLEDB maps OLE DB interfaces and methods over SQL Server data sources without using the ODBC API or the SQL Server ODBC driver as intermediaries. There are differences between SQLOLEDB and MSDASQL. The two providers support different connection properties, and SQLOLEDB does not support the use of an ODBC DSN connection. A to new Q2: The problem is the following. When you use CursorLocation equal to adUseClient the only cursor type for use is adOpenStatic if yiu use another cursor type ado will use open static cursor. When you set adUseServer in your cursor location you can select every cursor type. Cheers!!!;) Chau!!! Carlos Antollini. Re: Two questions about ADO ... Hadi Rezaee24-Oct-01 19:27 Hadi Rezaee 24-Oct-01 19:27  Hi again Mr.Carlos ... Thanks again for your answer ... your help was useful ... I got my all answers, only i have theory question about CursorLocation, still: If i wanna write my program for the Server computer, i must change CursorLocation to adUseServer ? and If i wanna write my program for the Client computer, i must change CursorLocation to adUseClient ? Is it right ? Is it for all databases ? With Warm Regards, Hadi ! My month article: Game programming by DirectX by Lan Mader.

Carlos Antollini26-Oct-01 10:10 Carlos Antollini 26-Oct-01 10:10  I'm sorry Hadi, I have no pardon.... First. Is true you need to use the cursor location over the server. The explanation is the following. When you select Client Side, the bookmarks, moves, etc are used in the side of the client, dependes the resources that you have in your pc. When you select server side, the cursor is used the side of the server. The problem is that some databases have no cursor in the server side like Access, because access is not a server. Is like a PassThrought. If you are writting a program for SQL Server the best is to use the cursor location in the server side, because in that mode you are using the cursor provided for the server, and the server resources for that operation. Is Clever Now?;) Bets Regards. If you don't understood, notify me, because my English is not as well that I want... Carlos Antollini. Today is friday!!! for All!!! Re2: Two questions about ADO ... Carlos Antollini26-Oct-01 10:15 Carlos Antollini 26-Oct-01 10:15  In resume, you need to know what is better for you database, for example if you are using a Jet Database like Access, dbf, etc the only option is adUseClient. If you are using Database Server like SQL Server, My Sql, Oracle, SyBase, etc the best is adUseServer, but you have the option of adUseClient, but the best for this case is adUseServer...

When I wan't to enable/disable them I use the member variable I've create just for them and call theControlVariable.EnableWindow(TRUE); and it's work very fine... except for push button who become enable and immediatly after disabled... why? thanks Remi Morin Rmorin@Operamail.com Remi.Morin@Lyrtech.com Re: CButton in a CDialogBar are disabled Tomasz Sowinski24-Oct-01 8:23 Tomasz Sowinski 24-Oct-01 8:23  CDialogBar uses command UI update mechanism for buttons. You should add ON_COMMAND handler in the frame class - this will solve the problem of disabled button and provide a place for code which will be executed when user pushes the button. If you want to conditionally enable/disable the button, add ON_UPDATE_COMMAND_UI as well.

And how to do this for multiple instances of IE? This is for a little program to monitor Web contents that is viewed on a LAN (to keep an eye on naughty students ) Thanks Kuniva Re: getting internet explorer address 24-Oct-01 7:36 24-Oct-01 7:36  Use the BeforeNavigate2 event from IE and write a Browser Helper Object DLL, this will work with every instance of IE. Use google.com to search for "BeforeNavigate2" and "BHO", you'll find enough resources regards Re: getting internet explorer address LukeV24-Oct-01 7:40 LukeV 24-Oct-01 7:40  http://codeguru.earthweb.com/ieprogram/enumIE.html there you go... 90% of your work is done!

I know how to open and read from a file, but how can I read exactly line after line? regards Re: Counting lines in textfile Tomasz Sowinski24-Oct-01 7:36 Tomasz Sowinski 24-Oct-01 7:36  Are you using FILE*, MFC's CFile, standard C++ iostreams, or pure Win32 CreateFile? Tomasz Sowinski -- http://www.shooltz.com Re: Counting lines in textfile 24-Oct-01 7:39 24-Oct-01 7:39  I'm familar with FILE* and CFile. If possible, I'd like to use pure Win32 without MFC Re: Counting lines in textfile Tomasz Sowinski24-Oct-01 7:51 Tomasz Sowinski 24-Oct-01 7:51  If possible, I'd like to use pure Win32 without MFC You'll have to look for line breaks yourself - Win32 API doesn't differentiate between 'binary' and 'text' files. Call ReadFile in the loop until EOF and search for \n in the input buffer. Tomasz Sowinski -- http://www.shooltz.com Re: Counting lines in textfile 24-Oct-01 7:58 24-Oct-01 7:58  Ok thanks I will try Is there an easier way with MFC? Re: Counting lines in textfile Tomasz Sowinski24-Oct-01 8:12 Tomasz Sowinski 24-Oct-01 8:12  Is there an easier way with MFC? Yes, there is. Use CStdioFile, pass CFile::typeText when opening the file, and call CStdioFile::ReadString until you reach EOF. Each ReadString reads one line of text. Tomasz Sowinski -- http://www.shooltz.com
