Does anyone know of a good 3rd party reference for Win32 API for .Net where VB.Net is the target language Most API references target C as the language of choice. Frankly, I hate C and all C like languages.

View 6 RepliesI am using Umbraco (a .NET CMS), and it has a reference to a specific version of a DLL (see 1 Umbraco Reference below). This is fine until I try to hook into the .NET MailChimp API which references a different vesion of the same DLL (see 2 PerceptiveMCAPI below).I can think of a couple of options for resolving this
a. Get either the Umbraco or PerceptiveMCAPI source and reference the same version of the DLL, really do not want to do this for compatibility reasons
b. Dump the 2 DLLs in the GAC, I want to avoid this as I see deployment issues arising if someone forgets (I know we should have an automated deployment but time is restricted)
I remember that there is a third option to specify what version of the DLL to use in the configuration. Is this possible and what is the code for it?

View 2 RepliesI am trying to create a small utility that tracks desktop usage in detail, to the level of individual text boxes etc.... in other applications. However, it is proving quite tricky. I thought I had it nailed using the Windows api. The below code is just a snipet of the code but essentially it provides me the handle of the control that the mouse is over. I thought from here, it would be easy to to the same thing but to provide the handle of the control that the cursor was actually clicked on, for example, if someone is filling in a text box in an application, they would not necessarily move the mouse to get to the text box, they may tab to it. Does anyone know if there is a way to get the handle of the control that is in use?

View 11 RepliesI have a Delphi program that communicates with a vb.net dll that I created. The vb.net dll communicates with a Fluke scope meter via an RS232 connection. I have created a program that communicates correctly via RS232, giving me the anticipated value. Though, when I package this up as a dll and access the dll from my Delphi program I always receive a value of "1", rather than the value I was expecting (most cases a value in and around 240).I know that my delphi program is definitely communicating correctly with the dll and that my dll is definitely communicating with the scope meter

I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways:The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable.
My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... EDIT There are over 70 imports to the user32 DLL.(The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)
I try to change some printer settings using the win32 api OpenPrinter,GetPrinter and SetPrinter in VB.Net application.I copied most of the code from this or related newsgroups.
