问题 The below code is for converting a zip file to base64 format.

问题 I am querying a pipe delimited text file using VBA with ADODB. I have tried using both the ACE and JET engines, but the results are the same, and not correct. I saved a "schema.ini" file in the directory telling the engine that the file is pipe delimited. When the query finishes though, I have data that shifted columns and other fields that are blank when I can see the data in the text file. I use the CopyFromRecordset method to transfer the results to my workbook. Can anyone see something

问题 We migrated some obsolete code from VB6 to VB.net and the previous code used ADODB for connecting to oracle. Below is how the code looks like Dim cmd As New ADODB.Command ' stored procedures execution here cmd = Nothing // I want to dispose this cmd Object Nothing worked in VB6 but its creating lot of trouble with .NET there are open cursors on database. I know we should use the latest library and get rid of ADODB but for now is there a way I can dispose this object. I tried cmd.Dispose() but

问题 How do you select rows based on a multi-value Lookup field in an Access database? The below ASP code returns no value when using multi-data column: <% Dim Contractors Dim Contractors_cmd Dim Contractors_numRows Set Contractors_cmd = Server.CreateObject ("ADODB.Command") Contractors_cmd.ActiveConnection = MM_Listings_STRING Contractors_cmd.CommandText = "SELECT * FROM Contractor WHERE UserStatus = 'Active' AND AgentID= "& Session("AgentID") Contractors_cmd.Prepared = true Set Contractors =

问题 Quick question about ADODB recordset. I want to extract a query result from a recordset and set it to a string variable: query = "SELECT Value1 FROM Table" RS = New ADODB.Recordset RS.Open(query,Conn) The query is always going to return 3 values. I want take to assign these three values to a variable. RS.GetString returns the query results tab delimited, but I want to be able to iterate through this set and assign each row result to its own variable. Any ideas? Thanks in advance! 回答1: You can

问题 Context: MS Access and JScript I have a table into which I insert one field's worth of data so that the autonumber will fire and give me that record's unique id, viz oConn.Execute( "INSERT INTO tbl (DateTimeStamp) VALUES (" + newNow + ");"); in this case, newNow is a Double value which is automagically coerced into a Date. Once that's done, I would like to retrieve the autonumbered ID field which should have been filled at the point of INSERT. Up until now I've been using ADODB.Recordset for

问题 Using VB to query an access .mdb database via ADODB. My date column holds both date and time, I would like to to build a query which will ignore the date, and refer only to the time in that column, in such a way, that will enable me to return records that have their time in between a range given by the user, ignoring the date. I tried selecting between numbers, but I believe access I'm doing it wrong ...WHERE [Date_Time_Of_Birth] Between #04:00:00# and #06:00:00# Just doesn't work as intended
