问题 OK, so I have a C++ project that compiles to a DLL file. I am able to reference this file in C# and see/use all of the objects and functions within the DLL file. What I need to do is to reference those objects and function through VB6. The C++ code has nothing in it that looks like it's creating a DLL. There are no '__declspec(dllexport)' modifiers, just C++ code. There are objects like this: String ^ Array^ I'm not entirely sure what they are. My knowledge of C++ is not very extensive and I

问题 To receive the bounty, please provide an answer with working code. Thanks. I have a stdole.StdPicture Object of the Type vbPicTypeIcon. I need to convert it to Type vbPicTypeBitmap. Due to project contraints, I need to be able to do this using Win32 or VBA. I am trying to load a file's icon to a command bar button. Here is what I have so far. It produces a lovely black square:) I am really new to graphics land so pardon me if it's a basic question. Option Explicit Private Const

问题 I have a series in Outlook with a few exceptions. What I would like to do is remove all exceptions from this series. Does anyone know if there is a way to do this? Since the exceptions list is read-only I have tried clearing the recurrence pattern and re-applying all of the values sans the exceptions list like this: Dim tRType As OlRecurrenceType Dim tRPSD As Date Dim tRPED As Date Dim tST As Date Dim tET As Date Dim tOcc As Integer Dim tInterval As Integer tRType = oAppointmentItem

问题 I have a VB6 App that uses a .Net component (via a .tlb reference in the VB6 app) which is working fine when executed as a compiled app, but it produces an error from the VB6 IDE a certain point when it is trying to use the .NET component. I should note that the error occurs when the .NET component is meant to be invoking a third party reporting component. The error is specific to the reporting component. Something about not being able to cast from String to some other type. The .tlb is in

问题 I am trying to insert an image into a word document using the Microsoft word 15.0 objects library included with VB^ and the only way I've seen to insert a graphics file is through this: oDoc.Range.InlineShapes.AddPicture ("C:\Users\name\Desktop\file.jpg") But, I want a picture that can be positioned over the text and where I want it in the document... Is there any way to do this using VB6 Code? 回答1: Word has two different ways to manage images and other embedded objects: as InlineShapes and

问题 I need to play a sound (.WAV file) from a Visual Basic 6 application. However, the PC is equipped with multiple sound cards and the user should be able to use it. Up till now a default sound card was supported and I would play a sound like this: CommandString = "Open " & Chr$(34) & mstrFilename & Chr$(34) & " type waveaudio alias MediaFile" mciSendString CommandString, vbNullString, 0, 0& If PlayFromPercent <= 0 Then CommandString = "play MediaFile" lngRetcode = mciSendString(CommandString,

问题 so my question is relatively simple, can I create VB6 application that references a class in a dll, and then substitute that dll for another at runtime? Now my intial guess is... no chance in VB6. So my thoughts turned to a VB.net interop dll. Could I do it in here, and then call the interop dll from the VB? Again, my guess would be no.... but I'd be happy if someone knew differently. The only thing that I think would actually work would be DI in .Net, but I'm limited to .net 2, or 3.5 at a
