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.
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?
Im working with a CD722UN Customer Display for our POS application. it comes with a USB2.0 connection and a installation package containing a driver etc. now, for my application. how should i do when i want to access this driver? at the moment i'm using the "CD722UN application"s .dll path but that can wary from clients OS etc. [Code] my first thought was to first check if there was a device installed in the device manager and somehow use the driver from there? [Code] what is the best solution?

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.

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.

I am trying to preinstall an .inf driver after my windows program loads and was using this question as an example. I am writing in VB.Net while the original question was done in C# so it might be something I lost in translation but here's what I have:

First off, apologies, I am probably diving in a bit too deep with this one. I am trying to find the current version of the drivers in my machine. I have a list of the GUIDs and friendly names by using the following code:
I have a problem connecting with mysql server 5.1. I tried several methods and been a lot of googling too but can't find the solutions yet. Here's the installed component btw[code]...
