I am now programming through OLE against Outlook and would like the same functionality. I have been browsing through the Outlook object model but can't find an appropriate object or method. Does anyone know of an object/method that I can use to get the primary SMTP address? Below is the current

问题 I have an Access .mdb database and I want to insert an image from an application developed in visual C# 2010. Pictures are stored in the database in the field of OLE-object. After adding images directly in Access they are stored in the format of an Bitmap Image. These pictures can be opened in Access with a double-click. I have the following code: OdbcConnection Connection = new OdbcConnection(); ... sql = "INSERT INTO film (poster) VALUES (" ' " + Image.FromFile(textBox8.Text) + " ' ");"; /

Embed files into Excel using Apache POI

由 天大地大妈咪最大 提交于 2019-11-27 01:59:13
I am exporting data to Excel file using Apache POI. In one weird requirement, I need to embed one file in the Excel using this POI. I have the file, and can be taken into streams or as byte arrays. After googling for much time, I am in a doubt whether POI really supports my requirement. Can we embed files into Excel? :-( Cheers, Anoop Ok, this took very long to finally work out, as there were a few things which didn't look very important at the beginning, but actually corrupted the file when they haven't been set right - especially in the Ole10Native wrapper, part of the unknown2 field

使用sp_addlinkedserver、sp_dropserver 、sp_addlinkedsrvlogin和sp_droplinkedsrvlogin 远程查询数据

一、sp_addlinkedserver 创建链接服务器。 链接服务器让用户可以对 OLE DB 数据源进行分布式异类查询。 在使用 sp_addlinkedserver 创建链接服务器后，可对该服务器运行分布式查询。 如果链接服务器定义为 SQL Server 实例，则可执行远程存储过程。 1、语法： sp_addlinkedserver [ @server= ] 'server' 　　　　[ , [ @srvproduct= ] 'product_name' ] 　　　　[ , [ @provider= ] 'provider_name' ] 　　　　[ , [ @datasrc= ] 'data_source' ] 　　　　[ , [ @location= ] 'location' ] 　　　　[ , [ @provstr= ] 'provider_string' ] 　　　　[ , [ @catalog= ] 'catalog' ] 2、参数： [ @server = ] ' server ' 要创建的链接服务器的名称。 server 的数据类型为 sysname，无默认值。 [ @srvproduct = ] ' product_name ' 要添加为链接服务器的 OLE DB 数据源的产品名称。 product_name 的数据类型为 nvarchar(128 )
