I'm logging into Outlook 2007 from my application and can enumerate the Accounts .Item[i] objects to look at Account settings. What I'm unable to find is: How can I determine (using the Outlook 2007 object model ) which one of these is the default Outlook account? There is no such thing as Store.StoreAccount as suggested here for Redemption (which I don't use). This SO post does not have an answer Firstly, there are 3 types of accounts - store, mail and address book. Which default account do you need? Secondly, you can use IOlkAccountManaget object (look at it in OutlookSpy - click

I have a inventory/Contact database where I need to store a lot of images (10k items, 1k people). Now, obviously ole object is out of the question due to the sheer bloat. Is there a better way to do this, such as storing the pathway to the image ( would be stored in a folder with the database) and having that image displayed where I need it(this would be great because some items are repeated)? Is there anyway to do this? (also, i really need to have a filebrowser to the actual image instead of typing the path manually (that would be hell)) Here is a concept Sub Locate_File() Dim fDialog As

I have a Delphi 2006 BDS application with the following code to iterate outlook mailboxes and then the Inbox and Sent Items within the mailbox: try nameSpace := outlook.GetNameSpace('MAPI'); // load the mailboxes mailbox := NameSpace.Folders; for i := 1 to mailbox.Count do if Pos('MAILBOX', UpperCase(mailbox.Item[i].Name)) > 0 then begin rootNode := trvwOutlookFolders.Items.AddChildObject(nil, mailbox.Item[i].Name, nil); for j := 1 to mailbox.Item[i].Folders.Count do if (Pos('INBOX', UpperCase(mailbox.Item[i].Folders[j].Name)) > 0) or (Pos('SENT ITEMS', UpperCase(mailbox.Item[i].Folders[j]

Borland Developer Studio 2006, Delphi: I have a TOLEContainer object with AllowInPlace=False. When the external editor is closed and changed my OLE object I have to do something with this OLE object inside TOLeContainer. The problem is I can't catch a moment when the external editor is closed. OnDeactivate event is not working. Probably I should change the source code of TOLEContainer adding this event myself, but I don't know where is the best place for it. Can you advice some method? A simple example which does not need modifying the VCL sources; uses .., activex; type TForm1 = class(TForm,

数据库访问接口发展历史 ODBC ODBC（Open Database Connectivity，开放数据库互连）。要了解ODBC是什么，先了解一下数据库连接的相关知识。在最开始连接数据库时，由于数据库种类繁多，各种数据库连接有不同的需求，这个时期，数据库连接主要依靠各种API函数来进行连接。在这种背景下，微软于1992年发表了ODBC， ODBC就是将这些API函数封装起来形成统一的接口。当SQL语句进入接口后，驱动器管理程序将它们送入对应的驱动器(driver)，由驱动器将SQL语句送入各种不同的数据库。 OLE DB OLE DB（Object Linking and Embedding, Database，对象链接嵌入数据库）是微软为以统一方式访问不同类型的数据存储设计的一种应用程序接口。OLE DB 是建立在 ODBC 功能之上的一个开放规范。ODBC 是为访问关系型数据库而专门开发的，OLE DB 则用于访问关系型和非关系型信息源。OLE DB可以通过ODBC连接到数据库，也可以直接连接到数据库，并且直接连接的访问速度更快。可以知道，只要支持ODBC的数据源是一定能够支持OLEDB的，但是反过来则不一定。 ADO ADO（ActiveX Data Objects，ActiveX 数据对象）在1996年8月与OLE DB一起被发布，是在OLE

I am using Delphi along with WinHTTP to do an HTTP request to download some files from the internet, and I can do the request but I don't know how to get the IStream from the OleVariant that is returned from ResponseStream . I have spent a lot of time googling but I can't figure out how to do it. Here is what I have tried: var req: IWinHTTPRequest; instream: IStream; begin req := CoWinHTTPRequest.Create; req.Open('GET', 'http://google.com', false); req.Send(''); if req.Status <> 200 then begin ShowMessage('failure'#10 + req.StatusText); FreeAndNil(req); Application.Terminate; end; instream :=
