c# - Store Byte[] in Access 2010 -


Simple work such as: How to store byte in Access 2010? See this for the entire day on the Web.)

I have to use the "attachment field" in Access 2010 because as far as I can see available any possible (varBinary, Image, ..) is not a field.

I tried: (ConvertImageToByte returns a byte []) 

  Cmd.CommandText = "Update Club Set Field 1 = @File Where Name = @Name"; Olead papermator para = new OLDP parameter ("@file", OLDB type Verbari); Paragraph Value = convertimagetoobet (logo); Cmd.ExecuteNonQuery ();

Exception: "Can not include a multi-value field to delete an update or query."

I tried: 

  DBEngine DBE = new DBiGin (); Database db = dbe.OpenDatabase ("database.accdb", incorrect, incorrect, ""); String command = "select * club"; Recorset RS = DB OpenerCenset (Command, RecordSet Type ANU DB Open Deinetate, 0, Lock Type ANM DBOptimic); Rs.MoveFirst (); Rs.Edit (); Recordset 2 RS2 = (RecordSet2) R. Field ["field 1"] Values; Rs2.AddNew (); Field 2 F2 = (Field2) rs2. Field ["FileData"]; F2.LoadFromFile ("file.png"); Rs2._30_Update (); Rs2.Close (); Rs._30_Update (); Rs.Close ();

This works but the file is in the first line of the table all the time and I can not understand how to get the correct line if I try to add a WHERE clause to the SELECT statement If so, get very few parameters. 2. Expected "Exception.

If anyone gets information about the story of my byte [] (or an image), please tell me to get it again!

Please do not give me the link for:

Thank you for helping friends.

You can use an OLE object field, this verb (max) Good choice.

Some notes: 

  "Reference: String dim dao.Recordset dim mstream ADODB as strCN dim as Microsoft ActiveX Data Object XX Library DRSQL string. Stream strSQL = "Select" Table 1 with Table "set RS = CurrentDb.OpenRecordset (strSQL) set mstream = New ADODB.Stream as mstream.Type = adTypeBinary mstream.Open mstream as. LoadFromFile "c: \ docs \ project.jpg" '' Filename & amp; Fullpath rs.AddNew rs.Fields ("Pix"). To copy back to disk, you must  
  edit   
  
  
 Dim strSQL String dim cn New ADODB.Connection dim mstream New ADODB.Stream strSQL = "Select" Table 1 with Table "set as root (= CurrentDb.OpenRecordset) as can be used as (strSQL: stream). ) Mstream.Type = adTypeBinary mstream.Open mstream.Write rx pst mstream.SaveToFile "c: \ docs \ pixout.jpg" !, adSaveCreateOverWrite

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
