Creating Activex DLL In VB 2008?
Jan 15, 2010
I have looked all over the web for a way to create an activex DLL in VB 2008. I have seen instructions for VB 2005 and VB 6. They both mention that I need to create a new project and use the template Activex DLL for the project, but I do not have the option "Activex DLL" for a template. Is there a way around this or can i download the template from somewhere? The background to the problem is that I have a DLL file (compiled in Delphi) that I can load and use correctly in VB 2008. I want to use VB 2008 to make this an Activex DLL so that it can be used with ASP.net. I have had no such luck. I have created a DLL using the Class template, but this DLL cannot be registered with the regsvr32.exe for usage with ASP.net.

Is there a manual or can someone provide a description on how to use the Microsoft Visual Basic/C++ 2008 Express Edition to create a .ocx or activex file? I have an application where I need to create and OCX to embed in a 3rd party software program. I have the application developed but I need a .ocx file to register the application for the project. I did this a while back in V6 but the newer version seems to be different

What I'm trying to do is get the information stored in a little "electronic card" trough a reader connected to my comport. I found a ActiveX protocol to communicate with the reader, but I've no idea how to use it. I'm pretty new to VB.net, and I don't have much experience in coding.So what I'm asking for is how do I use a protocol like this in a VB.net project?
Dim reading As New EmitEpt.EptReading
But that gives me the error "'EmitEpt.EptReadingClass.Friend Sub New()' is not accessible in this context because it is 'Friend'."If I remove "New", then I get the following error: "object reference not set to an instance of an object".

I am a competent (but not much more) VB6.0 programmer. I'm still developing software in VB6 and want to upgrade to VB.NET. I primarily write simple software to control proprietary hardware which is called by Active X. I need to figure out how to do this in VB.NET before I can switch over to the new version.In VB6, I connect to the VB6 by adding references to the DLLs (under project / references). When I load the main form, I declare:
Private Sub Form_Load()
Set o = New CBEDCSApp
End Sub

I have been trying for ages to put an ActiveX control on a windows form for a CCTV camera I am using. I have registered the control with windows, added it as a reference to my VS2008 project and now it appears in the toolbox.When I put the ActiveX control on the form I always get an error saying "Failed to create back buffer surface" The control is added to the form however I can not get it to work and I suspect it has something to do with this error.I have an example project from the developers of the camera that does not have this problem, i.e. I can add the ActiveX control with no problems, however the program is in C++ and I am using VB.Net.Is there anything else I need to do to stop this error from occurring?I am using a CCTV camera from Zavio (F521E). The ActiveX control is called AxVideoView.ocx.

Im trying to build an activeX control to be used in excel using VB08 Xpress addition. I have found instructions to create a Class Library Project, then add a user control. Under Build there is only one option, Build "Project Name", no options, no nothing. The build creates a .dll file not an ocx (which I was expecting?)
The problem is that when I compile the control I get a .dll file that I cant register as a activeX control, therefore I cant use it in excel. Ive tried to create stupidly simple activeX controls, ie one label that says "Hello World", still no luck. When I try and register the .dll file, it doest work, therefore no dice with excel.
The strange thing is that within VB08 Xpress I can use the control in any Windows Form Application I create.

I am having problem with Visual Studio 2008.... When i add the Microsoft ActiveX Data Objects 2.5 Library from COM References, and just run the blank form, it runs perfectly.... But whenever i declare anything related to ADODB like dim con as new ADODB.Connection, then after that it gives me error and doesnt run the project. A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll. After that if i comment that like (declaration), then error goes........ I tried uninstalling each and every component and VS as well but the error doesnt goes....i am using Windows 7 x64. The same is working in Windows XP x86 in my virtual machine..... as i am not able to start my project

I've seen quite a few questions about calling 32 bit ActiveX components on 64 bit platforms - as I understand it you can't create a 32 bit ActiveX component from a .NET application running in X64 (native) mode. This is OK and I think I understand it.But my question is more basic. Is there such a thing as a 64 bit ActiveX component? or is ActiveX always 32 bit, period?

I have a COM dll that has been developed under vb.net. The Control works just fine in IE 6 and IE 7, but when IE 8 tries to load the control, the browser crashes. I look at the event viewer and I get an error 1000 about iexplorer.exe and mshtml.dll. Do I have to build this com dll with IE 8 on my development machine? How can I track down what is wrong with the Control?

I am converting an application to Visual Basic .NET.I have an ActiveX DLL that I must use that contains a PublicNotCreatable class that contains these user defined types:
Public Type CSGSelectionItem
Primary As Long
Sub As Long
[code]....
I have come across a couple of problems with this. The most important problem is that VB.NET doesn't want to let me Redim the 'ItemList' of a variable with a type of CSGShapeSubSelection:
Dim cdtShapeSubSelection As CanvasSG.CSGShapeSubSelection
ReDim cdtShapeSubSelection.ItemList(lSelectionItemListCount - 1)
I get an error: 'Redim' statement requires an array.Also, it seems as though VB.NET has no knowledge of what CSGSelectionItem is. So, when I type:cdtShapeSubSelection.ItemList(0).I get no auto-complete suggestions of any value. I would have expected suggestions of "Primary", "Sub", and "OperationControlEffect", but instead I get "Equals", "GetHashCode" etc.

I have an activeX OCX which i used in my program in vb6 (it is a 3rd party component), it actually interfaces with a PLC to do some work. Now i am porting my VB6 app to vb.net (Console application), i tried to reference it and create an instance of the activeX. But i realised that my instance is always = nothing. Here is the code snippet of what am i doing and i have attached the activex ocx in a zip file. Will anyone test it if it will work in vb.net (Console apps only).

I created a program with a textbox on it and a button that does something with the text in the textbox.How do I make that program COM visible, load it and automate it from another project?My goal is to be able to automate the program using COM:
Dim myProj as object = createObject("myProgram")
myProj.setText("Hello World")
myProj.buttonClickEvent()
Similar to how you can load a new excel and automate via interop:
dim xl as object = createobject("excel.application")
Dim wb as object = xl.workbooks.add
Dim ws as object = wb.worksheets(1)
ws.cells(1,1) = "i love stackoverflow"
How do programs do this? I'm looking for the answer VB.Net specific.

I created an ActiveX Control in ATL, which I can succesfully use in for instance Internet Explorer. When I want to put that object in a VB.NET (2003) app, I get some problems.
First I 'Import' the control, using Visual Studio, so there are COM Interop DLLs created. Then I insert the control in the toolbox and drag/drop on a form. The control is succesfully created.
However, when I run the VBApp, it crashes. The debugger tells me that it gets a 'Class Not Registered' error.
Same when I create a pushbutton and create the object manually:
Code:
Dim AxQuest3DCtrl As Object
AxQuest3DCtrl = CreateObject("MyControl.MyCtrl.1") //crashes here
If AxQuest3DCtrl Is Nothing Then

I have created a VB ActiveX Control. I embed the DLL using the following semantics. It appears to be working fine in my local machine. However, it does not in other's workstation. But I was not able to generate the LPK file using the LPK_tool.exe since the ActiveX control did not show up in the list.
<object id="printUtil" name="printUtil" classid="CLSID:440616e0-8d63-47b8-b16d-4fd281dc652b" >

I develeped VB.NET solution composed of two projects: 1 Win Form project and 1 class library (.dll) project.I need to import all the .NET solution to a "Lab View" project ("National Instruments" product) as an ActiveX object (or suitable LabView object to import from .NET as well). The "Lab View" view interface shoulf have a button which call the WinForm interface.Is it possible? I think that there could be some problems with Win Form project, that is difficult to set inside an ActiveX .NET project.

I didnt know if this was the correct location to post this kind of question. My code is in C# however I am using the visualBasic. Interaction. CreateObject to connect to a OCX file. I notice that this works great for a while but if it continues to do its job for lets say a few days then I get and exception... "Can not create an ActiveX component." I am 100% sure that the ocx and dlls are registed correctly to the system.
