    c# sql ms-access ado.net oledb
    I’m trying to update a value in a MS Access DB (*.mdb) using OleDB in C#. Nothing fancy, except that I need to choose the row by an binary value, a VARBINARY(4). Naively I thought UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=01020304; would work. But is does not. Alternative tries were:UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=’01020304′; UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=’0x01020304′; UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=0x01020304; UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=CAST(‘01020304’ as VARBINARY); UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=CAST(01020304 as VARBINARY); UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=CAST(‘01020304’ as VARBINARY(4)); UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=CAST(01020304 as VARBINARY(4)); UPDATE MYTABLE SET VALUE= ‘new’ WHERE BINVALUE=CONVERT(varbinary(4),’01020304′); UPDATE MYT

    I am using OleDB in C#/.net and do not like the way oledb does parameters with question marks:using (OleDbConnection sqlConnect = drtevs.GetConnection()) {OleDbCommand command.CommandText = “UPDATE NAME SET FIRST_NAME = ?, LAST_NAME = ?

    c# oledb export-to-excel oledbdataadapter
    I am attempting to export rows of data from sql to excel but my Insert Command seems to fail every time. I have spent a good deal of time trying to create this but I have finally run up against the wall. The excel document is one that is generated by the IRS and we are not aloud to modify anything above row 16. Row 16 is the header row, and everything below that needs to be the data from sql. The header names all have spaces in them, and that seems to be where I am running into trouble.Starting at row 16 the column names are: Attendee First Name, Attendee Last Name, Attendee PTIN, Program Number, CE Hours Awarded Program, Completion DateThis is how I am attempting to write to excelprivate void GenerateReport() {FileInfo xlsFileInfo = new FileInfo(Server.MapPath(CE_

    c++ database oracle oledb oledbconnection
    SOLVED: My VC++ application was in 32 bit and my Oracle DB was in 64 bit. I initially though that the client would work with both versions of Oracle, however, it doesn’t. I thus solved the problem by reinstalling Oracle 11g2 32bit.I’m trying to connect to a test Oracle 11g2 database via Visual Studio 2008 in C++. My database instance name is ORCL.TEST.DB, an

    .net windows ms-access oledb outofmemoryexception
    I am having troubles with one of our applications. It’s .NET 3.5 32 bits process. Upon startup we open a .mdb to read a few “metadata” values. This works on hundreds of systems, but we have a customer with a TabletPC and problems. The operating system is Windows XP Tablet PC SP3, 32 bits, bla bla. Nothing unusual. It has .NET 3.5 (from Windows Update) All up to date. Nothing out of the ordinary.Since our application does a “few things” during startup, I’ve created the simplest console application ever:namespace TestAccessConnection {class Program{static void Main( string[] args ){OleDbConnection connection;try{connection =new OleDbConnection(“Provider=Microsoft.Jet.OLEDB.4.0;Data Source=metadata.mdb;Persist Security Info=False”);connection.Open();connection.Close();Console.Read();}catch ( Exception e ){Console.WriteLine(e.ToString());Console.Read();}}} }Results: If we execute that single .exe withou
