IDE - Upgrade To 2010 Projects Referencing A Class Library Targeting A Different Framework Fail To Build
Aug 18, 2010Say I have a Framework 4.0 project that is referencing a class library targeting 3.5. The project will simply not build. It won't give me any valid error message it will just act as though the reference does not exist.
Projects that were working like this in Visual Studio 2008 are no longer working in 2010. Took me forever to figure out what there error is. If I remove the project reference and add it back the intellisense lights up and you can tell a variable referenced in the class library is found. But as soon as you build the project everything is lost. My using statements get underlined, references to the variable all turn grey and project fails to build saying the class cannot be found. Once I make the class library 4.0 as well everything builds. I get the same issue between 4.0 client profile and 4.0 as well.

Aug 11, 2010I am trying to create a DLL from a class library in Visual Basic.
First I created a new Project in Visual Basic Express 2010 as a class library. Then I added a class which contains a function that I want to access in another program. This is why I want to export the class library as a DLL. In visual studio I am compiling the project which refreshes the saved dll in the bin folder of the project directory. When I open this dll or include it as a reference in another executable visual basic project, it does not find the function. how to generate a dll from a visual basic class library properly?
Here is the code of the class stored in the class library project:

View 2 RepliesMaking Apps Is Generating Serial Numbers For Software Projects
Sep 12, 2009Something ive wondered about as long as ive had an interest in making apps is generating serial numbers for software projects.Im wondering how is this done by the pro's so that someone can put a key into an app and without being connected to the net it knows the key is valid by using an algorythm.Id like to make something like that for the sake of learning how. I realise more and more programs now "call home" at the point of entering a key or to "activate" as with MS office and windows etc, but id like to start at the old school way of doing it.Generating the alpha numeric keys and also checking them.
View 10 RepliesCreate An Application Without Distributing A Referenced Class Library
Mar 1, 2011I am using VB .NET 2003. I have created a user defined Class Library and created a reference to it in my application. Is there a way I can compile the application so that the Class Library DLL is embedded into the application? I would really like to be able to distribute the application without having to distribute the DLL as a second a file.
In other words, I made a New Class Library lets say called TEST. I developed a new class within this library called MYCLASS. I built the Library TEST and created TEST.DLL. I then made a new visual basic project called APP1. I added a reference to TEST.DLL. I now can use TEST.MYCLASS within my APP1 project. The application APP1.EXE will run in the test environment, but if I move it to the runtime environment it will give me an error "File or assembly name TEST or one of its dependencies was not found". To correct this error I can place TEST.DLL in the directory where APP1.EXE resides. I would prefer not to have to put TEST.DLL in the directory. Can I easily compile it into APP1?

View 1 RepliesCreate A License Key Function For Application?
Apr 24, 2010I want to create a license key function for my application.
For example I want in this key to contact 2 values: registered_to, expiry_date.
I want the licence key to be some sort of large string like: 2349ASDGKLASD87ASDGALSDK8ASD80972K.
I would need to create some way to create keys use some sort of algorhithm that decrypts the key and grabs the registered_to and expiry_date values. It also needs to check that the key string has some sort of check digit like credit cards have, so no-one can just type in a few random letters/numbers and it accepts.
Write A Protection Procedure Which Will Allow To Create A License Key For Users?
Apr 9, 2010I am trying to write a protection procedure, which will allow me to create a licence key for our users. This licence key will ensure that the software can only run on the registered system, and will allow the user to access only specific areas of my program which is relevant to them.
I am thinking of using an RSA style approach to this where I want to be the only person who can create the registration keys. But I want to allow the program to be be able to decrypt the key. This is to prevent the average user from being able alter the key and remove any restrictions which are being imposed on the program by the license key.
The process that this would take is to produce a host id which has went through a series of tasks to distort the actual value from the user will return this code us, and from this host id I can then work out the original value of the code. Using these public and private keys I can then encrypt license key information.
However I would like to know how I would implement the private key encryption and key generation program in .NET, so that I can get this setup working in a manner which will allow me to generate keys and allow the program to decrypt keys.

View 2 RepliesAdding A Windows Service Class To A Class Library
Feb 14, 2012I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.
View 1 RepliesDLL Import - DLLs Were Re-compiled As 64-bit DLLs And They Still Don't Work?
Apr 6, 2010I 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.

View 1 RepliesVS 2008 Create An Interface Between A Third Party Application Which Can Make Use Of C/C++ DLLs
Nov 30, 2010I 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.

View 4 RepliesClass Module Which Is Shared Between The 2 Projects?
Mar 29, 2010I have no idea what is going on here but it is strange to say the least.I created a new solution in VS2008Pro under windows 7 This solution has 2 projects one for the pc and one for a CE based device.There is one class module which is shared between the 2 projects.In VS2005 under xp this same basic project worked fine but here I am seeing error messages that appear out of no where.
Example the CE portion flags 3 lines initially 1 related to a file i.o function and 2 others related to socket methods. All three of these were supported in VS2005 using framework 2.0 which is the same framework I am using here. This is just the tip of the ice berg however.If I attempt to run the code it runs fine for the pc client and of course not for the CE device. If I make any kind of change, add a line, comment a line or just add a comment I get lots more errors with odd messages that are not even valid.
In one case after I saved it jumped from 3 errors to 30, in another case to 50 and yet another to 144 errors yet the only errors that were present were the original 3 that were flagged.The ide threw errors like Try Catch must end with matching End Try.Get no longer supported ' apparently referring to the binary file get but here it is used as the get portion of the property.Get must end with matching end get.It also started complaining about functions and data types.For example saying "an is not declared" pointing to the word Boolean Or telling me my functions are not declared point to only 1/2 of the function name.
I do not see any errors in the code and it reports no errors in VS2005 under XP.As a test I tryed adding a new property to the project after it was telling me there were 144 errors. I allowed the ide to do most of the work and when I hit enter the errors went back to 3. Then I saved the project and the errors went to 105 pointing first at the new property just created.
