I have been digging internet for couple days, reading very old information, that leads to very old and nonexisting sites, still, I understood, what is needed to achieve my goal. We have a file.mdb on server running WindowsXP, so I need to add it to ODBC data sources. I do that with simple steps, ending up with "System DSN", that allows access to that .mdb file I need to install on this same server some sort of ODBC bridge, that would allow me to create remote connection to this server, making that bridge connect to servers ODBC DSN, and query out my stuff (could not find any free ODBC bridge)

I need to create an access (mdb) database without using the ADOX interop assembly. How can this be done? Before I throw away this code, it might as well live on stackoverflow Something along these lines seems to do the trick: if (!File.Exists(DB_FILENAME)) { var cnnStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + DB_FILENAME; // Use a late bound COM object to create a new catalog. This is so we avoid an interop assembly. var catType = Type.GetTypeFromProgID("ADOX.Catalog"); object o = Activator.CreateInstance(catType); catType.InvokeMember("Create", BindingFlags.InvokeMethod, null, o,

We are importing from CSV to SQL. To do so, we are reading the CSV file and writing to a temporary .txt file using a schema.ini. (I'm not sure yet exactly why are are writing to this temporary file, but that's how the code currently works). From there, we are loading a DataTable via OleDB using the following connection string (for ASCII files). "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + sPath + ";Extended Properties=\"text;HDR=Yes;FMT=Delimited\""; The problem we are having is that fields with more than 255 characters get truncated. I've read online about this problem and it seems that

I can't use average because maximum and minimum value goes to the same gray color. Or if there's some way to convert to another color palette. I can't find on Google a function to convert it. MATLAB uses some thing called rgb2ind but I would like to know the formula. 回答1: First let me create an indexed image using the Jet colormap: img = repmat(uint8(0:255), 100, 1); cmap = jet(256); imshow(img, 'Colormap',cmap) The straightforward conversion using

I have been asked to do some work with accessing MS Excel data using "Microsoft.Ace.Oledb". I have found this to be part of the "Microsoft Access 2010 Engine Redistributable" download. I would like to know if "Microsoft.Jet.OleDb" has replaced "Microsoft.Ace.Oledb" driver and are essentially the same or are they completely different things? Also, do you normally get

I am trying to determine how the code benefits from using polymorphism. class FlyingMachines { public void fly() { System.out.println("No implementation"); } } class Jet extends FlyingMachines { public void fly() { System.out.println("Start, Taxi, Fly"); } public void bombardment() { System.out.println("Throw Missile"); } } public class PolymorphicTest { public static void main(String[] args) { FlyingMachines flm = new Jet(); flm.fly(); Jet j = new Jet(); j.bombardment()

I'm writing a low level tool to scan and recover data from damaged Jet4 MDB files. I'm scanning through pages, parsing Rows, and decoding columns. If I have the raw 8 byte value for Datetime fields, how can I convert this to a string representation of the date such as "MM-DD-YY HH:MM:SS"? If I have the raw 4 byte value for a Number field with Single field size and 3 decimal places, how can I convert this value to a float/double? Are there any documents that describe how all of the access fields are encoded and stored on disk? Thank you. If I have the raw 8 byte value for Datetime fields, how
