Detect USB Port Version? nng3821-Jul-03 5:57 nng38 21-Jul-03 5:57  How to detect that your PC system has USB version 1.1 or 2.0 using Visual C++? Thank you very much Re: Detect USB Port Version? John M. Drescher21-Jul-03 6:14 John M. Drescher 21-Jul-03 6:14  Did you know that the standards committee wants to allow makers of USB 1.1 products to rename their product to be USB 2.0 without adding support for the faster speeds? I am not sure how this will affect your results but I wanted to inform you of this. I'll try to find the links.. Here is part of the article on the register (www.register.com): The trade group responsible for marketing the USB peripheral interface has the older given 1.1 specification a speed-boost -simply by changing its name. Of course 1.1, superseded by the much speedier 2.0 specification, hasn't really got any faster. But the USB Implementors Forum (USB-IF) has decided that vendors can describe USB 1.1 ports as USB 2.0 ports. Now they can describe the old specification as "Full Speed" and the newer, 2.0 specification as "High Speed." The Bangkok Post notes that this puts vendors in breach of EU trades description legislations. Whoops. USB 2.0 was never intended to be branded with a version number. Instead, the USB-IF dubbed it 'Hi-speed USB'. USB 1.1 was to be known as plain old 'USB'. Manufacturers have nevertheless insisted on sticking with the version numbers, which is what seems to have cause all the trouble. Apparently consumers were shunning older models. "I now understand the new full-speed and high-speed naming, but what is going to happen when USB 3.0 is released? Is it going to be 'Really High Speed'?," asks an editorial in GeekNews It's not the first bit of semantic ethnic cleansing we've seen this year. A handful of vendors have hijacked the 4G bandwagon, hoping that this will put them in the driving seat when the real 4G specification is passed.

Drescher21-Jul-03 7:11 John M. Drescher 21-Jul-03 7:11  It is no different from HKEY_CURRENT_USER just open the root inside of HKEY_LOCAL_MACHINE. John Re: writing to the registry Dominik Reichl21-Jul-03 7:12 Dominik Reichl 21-Jul-03 7:12  If you can write to CurrentUser, you can also write to LocalMachine. Just use HKEY_LOCAL_MACHINE instead of HKEY_CURRENT_USER... Accessing LocalMachine is exactly the same as CurrentUser..... -Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do??

Requesting column information for stored procedures through ADO connection Daed21-Jul-03 4:48 Daed 21-Jul-03 4:48  I am using ADO to connect to MS_SQL database. I need to retrieve the columns for a specific stored procedure in this database. I tried the OpenSchema method with adSchemaProcedureColumns as QueryTpe but an error "Object or provider is not capable of performing requested operation" occurs. These are the lines of codes that generates the error: // Establish connection ADODB::_ConnectionPtr MyConnection = NULL; MyConnection .CreateInstance(__uuidof(ADODB::Connection)); MyConnection ->ConnectionString = _bstr_t (ConnectionString); MyConnection ->Open(_bstr_t (L""),_bstr_t (L""), _bstr_t (L""), -1); ADODB::_RecordsetPtr MySchema = NULL; MySchema = MyConnection->OpenSchema(ADODB::adSchemaProcedureColumns); How can i get rid of this error and retrieve the stored procedure. Is there a solution to get rid of this error? or may be another method that can be used. Re: Requesting column information for stored procedures through ADO connection Jon Hulatt21-Jul-03 5:30 Jon Hulatt 21-Jul-03 5:30  I don't know how/if you can do that with ADO. Since you're using sql server, there are a bunch of methods you can use to retrieve this information though. You can use the system tables to retrieve information:- select * from sysobjects o join syscolumns c on c.id=o.id where o.name='p_YourProcName' Alternatively, retrieve more wholesome information with the sp_help procedure. sp_help 'p_YourProcName' Personally, I prefer using the direct sql method with the system tables. For two reasons. 1) SQL Query Analyser colours the object names a pleasing shade of green, and 2) It creates potentially very lucrative future compatibility "problems".

Re: Requesting column information for stored procedures through ADO connection si_6921-Jul-03 5:43 si_69 21-Jul-03 5:43  i use stored procedures , you could try it like this, it works for me. hope this helps si CString strSQL; strSQL.Format("exec all_students '"+StartDate+"' , '"+EndDate+"'"); _variant_t vstrSQL; vstrSQL.ChangeType(VT_BSTR); vstrSQL = strSQL; m_pDoc= GetDocument(); cpSet.CreateInstance(__uuidof(Recordset)); cpSet->Open(vstrSQL,m_pDoc->cpDb.GetInterfacePtr),adOpenDynamic,adLockOptimistic,adCmdText); while(!cpSet->adoEOF) { cpSet->MoveNext(); } cpSet->Close(); Re: Requesting column information for stored procedures through ADO connection Daed21-Jul-03 19:53 Daed 21-Jul-03 19:53  I guess this works fine but it retrieves the data from a stored procedure. What i need is to retrieve the columns names and their type. Any Ideas?! Re: Requesting column information for stored procedures through ADO connection si_6922-Jul-03 5:54 si_69 22-Jul-03 5:54  add this into a stored procedure and the call it like i mentioned in my answer before DECLARE @TableName VarChar(50) DECLARE @NumRows int SELECT @NumRows = 3 SELECT @TableName = 'mytable' SELECT COL_NAME(OBJECT_ID(@TableName),ORDINAL_POSITION) FROM INFORMATION_SCHEMA.COLUMNS WHERE table_name = @TableName AND ORDINAL_POSITION <= @NumRows hope this helps si Re: Requesting column information for stored procedures through ADO connection Daed23-Jul-03 5:21 Daed 23-Jul-03 5:21  I cannot change what is written inside the Stored Procedure, so i guess this way wont help me. I found a solution but don't know if it is the best one. I exected the command of type Stored procedure and form the recordset returned i was wable to retrieve the fields information. To overcome the retrieving of a long recordset i used "SET ROWCOUNT 1" before executing the command. If anyone has better way plz tell.. Thanks Re: Requesting column information for stored procedures through ADO connection Toni7821-Jul-03 9:40 Toni78 21-Jul-03 9:40  I don't use MS_SQL database but I have been using ADO a lot lately, and usually when you get an error such as yours, it means that you are sending the wrong request to the database (i.e. syntax is not correct, wrong parameters, etc). Hopefully, the other replies solve your problem, but I posted this message just in case they don't. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie CFile class to copy through a network connection Broker200321-Jul-03 4:11 Broker2003 21-Jul-03 4:11  Hello, Is CFile strong enough to allow a copy through a network connection (WAN) with some slow performance ?
