问题 I bring today another question that is burning my head, I do import a DAO 3.6 type library to my delphi 7, and I start to see many interesting intefaces so I face on intriguing question.

问题 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

问题 The following code fails with an OLE 800040005 "unspecified" error on the CentimetersToPoint call when executed in Delphi (XE), the similar VBS or VBA version passes var w : OleVariant; w := CreateOleObject('Word.Application'); w.Visible := true; Writeln(w.CentimetersToPoints(2.0)); FWIW the type library gives / [id(0x00000173), helpcontext(0x09700173)] // single CentimetersToPoints([in] single Centimeters); By default, Delphi only passes the floating values as Double, so I tried calling

问题 I want to manage with VBA an Excel file embedded in another Excel file. I can find many results with .docx documents, but I stuck with a .xlsx one. My last try is using OLE objects, but stuck at the line "SaveAs" (Error 1004). Here is the weird part: when I start debugging, or if I run the program step by step using F8, it did run, but no file were saved... I called my OLEObject "TEST" for this example: Sub testOLE() mPath = ActiveWorkbook.Path For Each obj In Worksheets(1).OLEObjects If obj

问题 I'm working on redeveloping an Access based system into c#.net, however when MS went from office 2003 to office 2007 they removed the picture editor within access - which meant that previously stored pictures would no longer display in the system. The guys at the company did a hack that basically saved the images with VBA using excel in the background (I can get more information if you need it) but basically it meant the access image controls could still be used (Object bound frames). However
