I have written an async UDP client to talk to a server at my company. When I run on my developer machine all is well. When I deploy to another machine I get a socket exception on EndReceive the first time I send data over the socket. My dev box is Win7 and I have deployed to both an XP SP3 machine and a Server 2003 R2 machine. Below is the receive code:

I have created a WCF service using vb.net. Everything works fine on my development machine but when I deployed it it failed with the following error'There was an error while trying to deserialize parameter [URL] I call a single method on the service and it has a single parameter called 'querys'. This parameter was a list(Of CustomType). I then created a new method with a single parameter of type ArrayList. Thinking that this should serialize. Again it works fine on my development machine but fails when I deploy it with the same error a above.
I am completely stumped how it can serialize a parameter on one machine and not on another. I've tried it on 2 other machine and it doesn't work on either of them. So that rules out a problem with the machine itself.All machines are running Win XP and .Net v3.5. The service was developed using VB .net in Visual Studio 2008.I have not included any code because the error is happening System.ServiceModel and as I mentioned above the code does work on the development machine.
I don't THINK it should be a credentials issue.I'm reading the credentials out of a database and using the same ones whether the program is running on my development machine (Win7) or my production server (Win 2008 R2).[code]
View 4 RepliesWe did development of a VB application on a machine with a high resolution screen. Also the machine where the real application runs has a high resolution screen. After a while we wanted to do minnor changes on the application and we wanted to use a low resolution laptop for that. When we opened the application for editing we saw that all forms changed their sized automatically AND unwanted.How can we build and change applications in one form size that does not change depending on the resolution of the machine on which edits are made?

View 5 RepliesI have just finished my application using VB in Visual Studio 2005 and it works fine on my Win 7 development machine. But when I install and run it on an XP machine it fails with an unhandled exception:System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154.
I've googled the error message and the solutions seem to be 1) compile as x86 (was doing that anyway), and 2) register the dll on the machine But firstly I'm not sure which dll I need to register, and secondly I don't want to be going around registering dlls - the whole point of the installation programs is that it should just install and configure everything automatically..
I wonder if/how to use a 32 bit DLL on a 64 bit machine. The situation is like follows:Autocad Inventor(64 bit program) can launch plugin DLL's. The plugin DLL in this case is programmed with VB.NET 2008 Express edition. As far as I know, I can only choose "Any CPU" when building the DLL with the Express edition. This DLL makes uses of a COM object called Isah IERPlink, a piece of software that is used with a 32 bit package. So in my bin directory this DLL will be added "interop.IERPlink.dll". I guess this DLL is specified for 32 bit CPU's, but I'm not sure.

I have created an application using VB 2008 Express on an XP machine. I created a deployment package and installed it on other XP machines with no problems. I tried it on a Vista machine and all seemed well until performing a serial port function. It simply halts/locks up. I have to close it in task mangler. I thought I would circumvent the problem by building and publishing it on the Vista machine. While running the program from VB express the program functions perfectly on that Vista machine, but when I publish and install it on same it still crashes at the serial portion of the program.

View 1 RepliesI've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads

View 9 RepliesHave built a project and associated it with a Setup&Deployment Project. The S&D project needs to contain 2 main folders (under User's Desktop) with various formats of files (xmls, txts, dlls) inside them and several subfolders. How can i copy/import these 2 folders and there sub-files/folders into my s&d project?
When adding them in the usual way, they are copied and defined a source path onto the current pc. You can understand what errors this might create when an another targeted pc does not contain those files to the exact location. Is there any way to copy them locally or somehow import them?

View 2 RepliesWe are in the process of creating active-x controls used within our application. Since Microsoft stopped supporting classic Visual Basic, is it wise to use Visual Basic to develop the Active X control or the latest VC++/ATL/MFC libraries provide more feature where we can create controls faster by leaving Visual Basic flexibility?
We will not be able to use .NET/VB.NET/C# since the application is supposed to work inside containers and containers may not support latest .NET runtime.
I am working on a VB6 project and my organization is planning to upgrade the technology from VB6 to VB.net. As I am new to VB.net windows application development, I dont know where to start and what to include in code. I have read that VB.net windows applications code should have AssemblyInfo, CultureInfo, Windows Security authentication etc. But I have still not found any article, code sample or VB.net windows application sample that could give me a complete list of features that an organization level VB.net windows application must have.
View 2 RepliesI am completely new to ASP.NET programming, and was asked to work on a small project involving ASP.NET, VB (which I am new to as well) and Microsoft SQL Server 2005.Being used to php/java I was hoping to find some kind of similar API to php.net and the javadoc. It would be very useful to have as I would prefer to work with a text editor, instead of using DreamWeaver or Visual Web Developer.In the project I basically only need to use ASP.NET to read from a SQL 2005 database and write to JSON files. where to find a clean and decent API to work with?
