VS 2008 Create An Interface Between A Third Party Application Which Can Make Use Of C/C++ DLLs
Nov 30, 2010
I am trying to create an interface between a third party application which can make use of C/C++ DLLs, but no interface directly to .NET. What I was hoping to accomplish (not sure if possible though), is create a very basic C++ DLL (not .NET), which the third party application would call directly. This DLL would contain a basic method such as "DoSomething()". Somehow, from my .NET application, I want to "listen" to this DLL and "takeover" the DoSomething() method, and then returning the result back to the DLL, which will in turn return the result back to the calling third party application.
I don't even know if this is possible because I'm sure I would somehow have to get a hold of the memory space of the DLL as initiated by the third party application. Also, it seems that creating a managed DLL does not work, based on feedback from other individuals who have tried this.

I am working on automation project for a 3rd party Application. This application has given APIs for various automation tasks (like, Menu automation, toolbar automation, etc)
My code is in VB.NET.
Automation could be made in client-server mode, my code being client, this 3rd party App being server. When I create an instance of 3rd party App ( using CreateObject(<progID>), it brings up its own GUI Framework.
I have my own GUI Framework with customised menu items as well as my some more automation code.
At present, both the GUI frameworks are floating in a dis-jointed and independent manner. I would like to contain the 3rd party GUI Framework within my own GUI framework whenever it is moved around.

I am trying to find a way to write a modular application.In this application there is a main form. Each module will be contained in one (or more) dlls. The idea is that a dll module can be dropped into the module folder and the application will be able to pick it up without the application having any prior knowledge of the dll existence.

We are developing an application in VB.NET 2008. We break the application into smaller multiple dlls so that we can easily update the program at the customer end.We want to know that is their any way to stop the other person to use my dll in their application?i.e we want to lock the dlls such a way that the dlls will be used by us only and not anybody in their application.Also we want to block viewing of dlls code using any code reflector

The error message that I've been getting for the past few months when trying to access functions of a specific third-party .dll using vb.net is this: "An unhandled exception of type 'System.AccessViolationException' occurred in test.exe Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
I've been researching this error message, and I have come to know that it is likely due to either attempting to access memory that isn't available or due to "enhanced" security features.I am trying to access a third party .dll. The functions in that .dll all deal in one way or another with Handle types (either returning them or accepting them as parameters). I understand that handle's can be essentially pointers to pointers (pointing to an entry in a memory table, which is itself a pointer), and I also understand that handle's don't, strictly speaking, exist in the .NET framework, but I do understand that through some combination of IntPtr's and possibly the Marshal class, they can be dealt with.
I don't believe vb.net's lack of a Handle type is the problem, because the dll function that I am calling, which on success returns a handle, returns a number <= 0 if the ip address it is searching for is not found, and the ip I specified doesn't exist. Also, the error really only occurs when executing the code from within the the Visual Studio environment. I compiled the executable and ran it 77 times(literally), and I only got the error on the 77th try.
I'm trying to find out all I can about this error. I would like to completely eliminate it. Could the error come as a result of something happening within the dll itself? The function asks for an ip address, and the ip address I have specified doesn't currently exist on the network, but as far as I know, the function handles that by returning a number less than or equal to zero. I am very confused as to what the problem could be. I have successfully interfaced with .dll's before. I've read about the hotfix for .NET 2.0 regarding this error message,but I'm a little skeptical. I've tried everything else I can think of, though, so I may give that a shot.I'm 100% certain that:
-I am calling the correct function within the .dll
-I am using a signature that matches the signature of the function
-The error has nothing to do with User Account Control.
The code is very simple to try to isolate the issue:
Imports System.Runtime.InteropServices
Module test
<DllImport("3rdparty.dll", EntryPoint:="#12")>[code]......

I am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.

I have developed a couple of windows applications in Visual Vasic Express 2008. To my horror, I have just discoved that the Setup Project is not available in the express edition.I have been searching to discover which DLLs I will need to include when using my 3rd party Deployment Application.
I know which ones I need for my 3rd Party Controls, but am stuck on which Microsoft DLLs will be needed the Microsoft Controls I have used, plus any other Common DLLs that are always needed.
I have tried searching Microsoft's site but without success.

I've been browsing around but the examples I find to do this are either for older VB (which I don't dominate that well and are having some trouble 'fixing') or quite basic and don't allow me to do what I want. Basically, what I want it to get the text on some of the text boxes on a 3rd party application. After some research I concluded these are considered child windows and... Well and from then on I found scattered pieces of information that keep me awake at night So, in order to get the text I want, what should I do?

I'm experimenting with a plugin architecture for my company's internal business system. I have managed to read all .DLLs in a Plugin folder which implement a specific interface. What I am trying to figure out is the best method of communication between the "host" MDI parent application and forms that will be in the .DLLs which I intend to make MDI children.
Currently, I am returning just ToolStripMenuItem objects from the .DLLs to add to the MDI Parent. I've also tested that events wired in the .DLLs to the ToolStripMenuItems do propagate to the code in the .DLLs. I've also managed to return a Form object via the interface and open that form, as the Plugin folder is being "scanned".
However, I am not clear how I would make these forms MDI children. Also, any other forms living in the .DLLs will also have to be MDI children. I created a VS 2008 Addin project just to see what's going on, and it seems that the Addin accepts an Application object on which it adds to the ToolStripMenuItems and does other operations. The code to build the menu inside the .DLL. This is opposite of what I have done so far, where the MDI requests a ToolStripMenuItem from each .DLL and adds the returned object to its own menu.
Would designing my plugin architecture to accept an application object in the same manner the only way I could get forms to open as an MDI child? Am I asking for other, currently unknown to me, headaches by NOT passing in the application object to the .DLL?

I am writing a small application that will display some info to my end user. I have another program that the end user will have open while running my appplication. What I am trying to do is have my application launch itself (and maintain positioning if other app location changes) and "tether" itself to the other application.Ideally the top left of my application would attach to the top right of the other application.I have tried for countless hours working with the GetWindowPos API but the values returned are either all zeros or it just doesn't work.I do a Try/Catch to see if the other app is running and I fetch the Handle of the process. This works fine. Then I try to get the positioning of this process and set my .Left property to the returned RECT's .Left property. no dice.This is Visual Basic 2005 ExpressOther application is a PuTTY window that is not a fullscreen app.
