How To Reference ActiveX Driver
Jan 9, 2009
I am working on a project that needs to using an activeX driver (libaray), a .ocx file. The driver have some properties and methods. I added the reference and have a new instance. When I try to put values to the properties, I got error messages from the driver.
Imports CBMCOMMLib
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[URL]
MaxTraces is one of the properties. Am I using the library correctly?

I have a VB6 based ActiveX dll file.
When i create a new Visual Studio 2010 web site, and i try to add a reference to that dll the following error appears:
A reference to 'dllName' could not be added. Converting the type library to a .NET assembly failed. Execution of the following process failed: C:Archivos de programaMicrosoft SDKsWindowsv7.0AinTlbImp.exe "c:mystitedllName.dll" /transform:dispret
[Code]....
If you delete some of these two functions the error doesn't appears. This problem is not present in Visual Studio 2008 or 2005.

I am attempting to move Visual Studio 2008 project from an XP Pro development environment to a Win 7 64-bit Ultimate environment. In the process of doing so, I have one ActiveX COM control that the project uses. I've installed that control using the maker's installer. Now, when I open the project, the project cannot find the control, etc. - "The system cannot find the reference specified." I also tried moving a particular file to the system32 directory, as per a possible fix they posted, but that didn't help either.

Trying to figure out if there is anyway built into windows 7/Vista/XP and/or Dpinst to verify that a driver is installed? I created a program that uses DPinst to install a driver and now I need to figure out how to tell the user that it is safe to close the program once the driver is install as the driver takes longer on some machines to install. Would anyone know how to get this to work?

I'm pretty sure the answer is no but I am curious, is it possible to write a driver in .NET code? I am talking more software driver here rather than hardware driver (ie something like a file system filter as opposed to a driver for a printer or something).

I have a requirement to convert a word file to PDF and to display it to users.It needs to be in PDF to prevent users making changes to the document.Only a few of the PCs which use the software have Word 2007 installed, most have Word 2003 but all have a third-party printer driver CutePDF installed.I would like to automatically convert the file to PDF using CutePDF without the user having to open a print dialog. In fact I don't want the user to have to do anything at all except request to view the document which will set the automatic process in motion.

Iīm using Windows 7, 64 Bit and Visual Basic form VS 2010 to develop an application.
I want to remove a HID driver with the Devcon.exe tool. Using the console (cmd.exe) with the following command, there is no problem. The driver ist removed immediatly.
D:devcon remove =keyboard "HIDVID_1784*"
If I try the same from the application with:
Shell("C:WindowsSystem32cmd.exe /k D:devcon remove =keyboard ""HIDVID_1784*""", AppWinStyle.NormalFocus, True, 1000)
or:
process.StartInfo = New ProcessStartInfo("C:WindowsSystem32cmd.exe", " /k D:devcon remove =keyboard ""HIDVID_1784*""")
process.Start()
then devcon returns the message:
"The 1 device(s) are ready to be removed. To remove the devices, reboot the system."
and the device is not removed or disabled, and of course, I donīt want to reboot the system.
Does anyone have the same problem or even better can tell me, how to solve this problem, so that the driver ist immediatly removed?

So - we are FED UP with our medical records packaging (document imaging) system and want to create a simple filing interface for our scanners to use in VB. Part of this deal is getting VB to interact with a TWAIN Driver.
There is some code out there for ASP.NET and C# - does anyone know of a VB.Net based code I could look at?
I have spent part of my day trying to recreate the ASP into VB but the calls are just different enough to get interesting.

After some digging around both here and the www in general I have plucked the following code to allow me to install a non listed printer driver to my XP machine. Problem is I am unable to get it to function properly.
The first section of the code creates the port every single time with out fail on any machine that I have tried but doesn't seem to function with the addition of the drivers.

It's been a while since i've posted. Happy Valentine's day! Requirement: I would like to interface my .NET application to a "virtual webcam driver" for the purposes of SENDING image frames. I'm happy to use an open source .NET or COM component if that exists or indeed implement a "webcam driver" from scratch if someone can point me in the right direction. My first priority is the functionality.
My second priority is low dependancy on 3rd party libraries and tech (aside from .NET of course I'd prefer not to involve directshow if possible?

I have been working with TWAIN driver for few days. I have learnt how to connect to the scanner or get the working scanners connected to the machine. I am having a problem now, eventhough i get connected to the scanner, I am not able to set the capabilities from my application. The scanner scans using the capabilities that are set on it but not from my application. I have looked at the sample code given with twain pro but even that doesnt set the capabilities of the scanner. For example if the scanner is set to 300 dpi and I set 200dpi from my application, the scanner scans with 300 dpi. It gives me an error saying that the value given is out of range.
