Inno Setup: Iterate through array of type Variant (from OleObject)

阅读更多关于 Inno Setup: Iterate through array of type Variant (from OleObject)

问题 I'm trying to read and write to the IIS 6 metabase using Inno Setup. I can't figure out how to access arrays though. IIS := CreateOleObject('IISNamespace'); Compr := IIS.GetObject('IIsCompressionScheme', 'localhost/W3SVC/Filters/Compression/deflate'); Arr := Compr.HcScriptFileExtensions; { ... [code to iterate and add items] here ... } Compr.SetInfo(); The metabase editor calls the object type I'm trying to access a "multi-string". VarType(Arr) yields 0x200C as type (see http://www.jrsoftware

阅读更多关于 Retrieve Outlook logged-in user SMTP address after connecting through OLE

Exchange Web Services has a ResolveNames() function that I can use to retrieve (among other things) the primary SMTP address for the Active Directory user that logged on to Exchange Server through EWS. 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 Delphi code that I use to connect to Outlook. For the default user logging in (AUserSMTP='') it

Excel unable to insert more than 255 chars?

阅读更多关于 Excel unable to insert more than 255 chars?

I am using OLE DB driver to insert more than 255 characters into an Excel sheet, but I get the error: Exception Details: System.Data.OleDb.OleDbException: The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data. Seems from this thread that it's an Excel limitation. Even the Microsoft site seems to say so here . So does this mean I can't programmatically, but I can manually? Because I can enter more than 255 characters when I manually type them in Excel. So is it a Microsoft.ACE.OLEDB.12.0(AccessDatabaseEngine.exe) driver limitation? The link

Can the .NET 4 Task Parallel Library use COM objects?

阅读更多关于 Can the .NET 4 Task Parallel Library use COM objects?

问题 This is an "is this possible, and if so can you give me a quick example because I can't find one online?" kind of question. I have a number of completely separate (i.e. "embarrassingly parallel") processes that I want to run in parallel using the Task Parallel library in .NET Framework 4 using C#. Some of these processes require the use of software that can be accessed via COM/OLE automation. Specifically, there is a Parallel.Foreach() loop that divides up the tasks from a list of items,

问题 I have made a vbscript to target some computers and do wmi queries on them, and my boss wants this data to be put inside a document. The problem is that this document is a Microsoft Word document with embedded excel objects inside it. Now I have searched wide and far on google on any way to target and manipulate an object inside and object with OLE, but I seem to be getting nowhere. So my question to you is if someone has some code for this I could look over or maybe a tutorial, and quite
