.net Remoting Returns System.BadImageFormatException?
Aug 4, 2011
I am working on a .net remoting project (VS 2008). I have a .dll hosted in IIS 6 windows server 2003 r2.
When i try to test it in internet explorer "http:localhost/hellone/test.rem", it shows the following error
System.BadImageFormatException: The format of the file 'SimpleTest' is invalid.File name: "SimpleTest"
at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase, Boolean isStringized, Evidence assemblySecurity, Boolean throwOnFileNotFound, Assembly locationHint, StackCrawlMark& stackMark) at System.Reflection.Assembly.InternalLoad(AssemblyNa me assemblyRef, Boolean stringized, Evidence assemblySecurity, StackCrawlMark& stackMark)

I'm trying to deploy a service created in VS2010 and am continually getting this error, along with the description that is expecting an application manifest, when trying to use installutil (.net 4.0)to install the service.I've developed the service both in a 32 and 64-bit environment, and tried installing in both a 32 and 64-bit environment. This does not seem to have an effect.

I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.
Service running under system account (in this example a simple console application)
Code:Imports ClassLibrary1Module Serv
Sub Main() Dim SDSIPC As Semaphore = CType(Activator.GetObject (GetType(ClientFromServer), "ipc://Client/SreeniRemoteObj"), Semaphore)
SDSIPC.DoSomething()

I am trying to write my first DLL and am struggling to get it working correctly and am receiving a variety of errors. For my Hello World DLL I was trying to follow this page [URL].. but as it was very old and referring to VB 6 I am now trying to use the instructions on this page: Essentially, what I have done is to follow all of the instructions on the second link, but then instead of calling it from C++ I call it fro my VB application (I have successfully managed to call DLLs from VB in the past). When I try to call the Add function (or any others) I get a BadImageFormatException error thrown saying "An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)" but I don't know what I am doing wrong. I have tried calling an alternative C++ function that is declared as a void and takes no arguements in order to completely avoid the problem of matching the data types but I get exactly the same error.
I gather that this is sometimes to do with target architectures, and have tried setting the C++ compiler to build it as both a Win32 DLL and as an x64 DLL, and each time changed the VB settings to match the outut type of the other but this doesn't seem to make any difference, and for some permutations even makes it worse with it saying that it can't find the entry point in the DLL that I'm calling.
I am completely new to this and am now at a loss for what to try and what could be going wrong,. The VB import is as follows:Private Declare Function Add Lib "DLL_Test.dll" (ByVal a As Double, ByVal b As Double) As Double Private Declare Sub HelloWorld Lib "DLL_Test.dll" ()

I have VS 2008 on Win 7 Professional 64bit system and database is Oracle 11g r2 installed on the same machine.
In Data Source Configuration Wizard --> New Connection
Data Source: Oracle Database (Oracle Client)
When I click Test Connection after entering Service name, username, and password I get the following error:
Attempt to load Oracle client libraries threw BadImageFormatException.This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.
-- I have no oracle client installed because there is no need in this case, I have the same setup on my laptop Win 7 32bit Oracle 11g r2 32bit and everything is working fine.

I've been trying to get the UNC path for a mapped drive in a web application written in VB.net 2005. I was able to get this code working[code]...
I tested this code out in a test application - just a simple web page. But when I plug the code into my actual project, it doesn't work. In my testing of other examples, I figured out that WNetGetConnection returns a system error of 487 - ERROR_INVALID_ADDRESS. But I don't understand why it would work in my test application but not my actual project application.

We have a vb application with many forms that contain a "lookup" button that has an icon called find.ico. Once in a while, a user will open one of these forms and get the below error but not every time. Has anyone else run into a similar situation? Since it is not consistent, it's been very difficult to track down.
Exception Source: System.Drawing
Exception Type: System.IO.FileNotFoundException
Exception Message: find.ico

I have a select statement which was returning the required values but when I changed the OS date from English(US) to English(UK), it now returns null. I believe the problem is concerned with date since in the query am selecting values where the date from the database is the same as the date in a combobox but I don't know what else I can do. It almost looks like the dates in the combox and in the database are not the same and yet the date in the combobox is actually retrieved from the database and has been returning values fine until I changed the system date format.Here's my select command:
cmd4.CommandText = _
"SELECT sum(brought_qtty), recieved_qtty from brought_coffee, centre_weigh where brought_date=#" & _
dtComb.Text.Trim & "#" & _[code].......

I am not the original author of this software project and the code is poorly documented. I am mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.

The Now() function in VB.NET returns date and time which is different from the system time that I see on the right-bottom on the notification bar. It is 15 hours slower than the system time. Has anyone ever met this problem? I'm using .NET 2.0.

Can we configure remoting for the LAN? I studied it halfway but I realised that its for web, but I think it can be possible for LAN too.

I am creating a client/server application that connects via .NET remoting and I'm using TCP. I have 2 config file for client and server. The config file and the server application runs good. But for the client, it runs even though the server is offline and no port is open listening. I've gone through quite a lot of example and don't really know whats happening. This is my client config file.

I currently had a .Net Remoting Application running on Framework 2 under IIS. I have to upgrade it to Framework 4 in order to use some new components. I have been able to set everything up and running smootly on Framework 2, but as soon as I change to Framework 4, I get the following exception when I try to call one of the function of my remote object.
The input stream is not a valid binary format. The starting contents (in bytes) are: 53-79-73-74-65-6D-2E-52-75-6E-74-69-6D-65-2E-52-65
This bug is not the real bug, it is caused by the fact that the remote object is throwing an exception, and IIS wrap the exception in XML, which throws the BinaryFormatter off.See this for more info on the bug.
This is very unfortunate because I cannot see what is causing the exception, and having never used any Remoting before, I do not have much ideas as to where to start debugging. It seems the Exception is thrown before even stepping in the code because I do a fair amount of logging and none of it seems to be triggering.Basically, I'm looking for some clues or pointer from people that encountered similar problems:
What could be causing the exception when no code has changed besides Compiling from .Net 2 to .Net 4?How can I get the full Exception message that is returned?

I have downloaded an application that uses .net remoting.
The problem is that I don't know how to configure it to communicate over the internet.
From the blog [url] says to set the tcp 192.168.1.100 . As far as I know this is the intranet IP. My external IP is different. Do I need a server or a Static IP from my provider?

I have an Addin for MS Excel which needs a singleton to share data amongst modules.Depending on the version of Excel (2003, 2007, 2010), and how Excel was started, it calls my addin from different, unpredictable AppDomains, which prevents the classic singleton approach.Creating a custom AppDomainManager won't work because Excel has already created the AppDomains before the addin is called.
Linking to mscoree to enumerate domains breaks the addin registration process (and I really don't want that anyway); there doesn't seem to be any other way of enumerating, so that isn't an option either.The only solution that I've found is to use remoting. Here's my test rig:
Imports System.Runtime.Remoting
Imports System.Runtime.Remoting.Channels
' Remeber to add reference to System.Runtime.Remoting DLL[code].....
Once everything is running, access to the singleton takes ~100µS, which is perfect. I can live with the ~400mS the first time each AppDomain is initialised. The problem is at startup, where the remoting invocation takes ~2.5 seconds.

We have a client server application that 650 users are using everyday. Lately they have started complaining about over all slow responses and slowdowns in normal application usage like searching, reporting etc.We are using .NET Framework 3.5 and .NET Remoting is the technology we have used for client connection to the server side. We can't remove that and use something else due to legacy application maintenance. We are using SQL 2008 R2 x64 on a very good server.We have gone though the basic steps of making sure that all the SQL side is ok everything is well tuned but we need to convenience the client that it is not the application but the database that needs to be regularly maintained by a DBA in order for it to run smooth due to the nature of the application making tons of changes and inserts in the database everyday.
Anyways I need to write some sort of module that can plugin into the .NET Remoting calls so it can log the normal usage of different methods on the server like;* How many times a remoting method is called* What params a remoting method is called with* How much time it takes to execute each remoting callIs there anything available in .NET Framework that can help me? I read something about .NET Remoting Sync but not too sure if that is what I need to use? If any can shed any light on the subject or nudge me in a right direction with some sample code, that would be great.

after my last post i dove into remoting to try to solve my performance problem in a client-server fashion.
This works very well, but i come across a big problem which i don't seem to get solved.
I made a well known singleton servicetype on the server that retrieve all customers. Whith 1 db connection this works fine. But very often customers and i use in 1 sql instance multiple databases (for each administration a separate db). so the whole purpose of a singleton object is hereby destroys as soon i connect in my class to a different db. Is there some way to overcome this for example threading or running multiple servers (for each db it's own server-application)?
