.NET 4 LocBaml: An attempt was made to load a program with an incorrect format.

  
I am testing out LocBaml and a simple .NET 4 Wpf program with a button and a label only. I add the following to the PropertyGroup in the .csproj file <UICulture>en</UICulture> Now I open a Visual Studio command promt and build both LocBaml and my test project with msbuild. Then I copy locbaml.exe to the bin\debug of my test project. Then I add uid's to the testproject  by running "msbuild /t:update LocApp1.csproj". Now it is time to generate the csv file by using locbaml. I enter "locbaml /parse en\LocApp1.resources.dll" from the bin\debug folder and hit enter. I get the following error: Microsoft (R) Baml Localization Utility 0.0.0.0 Copyright (C) Microsoft Corporation 2005. All rights reserved. Could not load file or assembly 'file:///D:\Projects\LocApp1Soln\LocApp1\bin\Debug\en\LocApp1.resources.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format. What am I doing wrong here? The file is there and ildasm only show a dependency on mscorlib for the satellite assembly.

Smartclient - Bind result: hr = 0x8007000b. An attempt was made to load a program with an incorrect

  
Hello,

When I run an exe hosted through IIS (as a smartclient) on 64-bit machine it fails with:

(From fusion Log)
Bind result: hr = 0x8007000b. An attempt was made to load a program with an incorrect format. ERR: Setup failed with hr = 0x8007000b. ERR: Failed to complete setup of assembly (hr = 0x8007000b). Probing terminated.

The exe WORKS when loading the exe normally (Double clicking on it)
It WORK through the Url when hosted on a 32-bit machine.
I have tryed marking the exe x86 in VS.

What is problem here? It seems related to 64 bit AND smartclients?

Thanks

Service Configuration Editor (SvcConfigEditor) in VS 2010: An attempt was made to load a program wit

  

I am using Visual Studio 2010 Premium installed on Windows 2008 HPC with service pack 2. I am attempting to use the Service Configuration Editor (SvcConfigEditor.exe with File and Product version 4.0.30319.1) to create a new service configuration.

1. I opened the web.config file for the WCF service

2. I clicked the link "Create a New Service..." to bring up the "New Service Element Wizard"

3. I browsed to the WCF service \bin folder and selected the DLL. I received the error dialog box containing the message:

Could not load file or assembly 'file:///d:\...\MyService.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

4. I made sure that the WCF service and all referenced DLLs are configured for the same Target CPU of x86.

Below is the FUSLOG viewer entry when this error occurred:

64 Bit ASP.NET Project - Attempt to load Oracle client libraries threw BadImageFormatException.

  

I am getting a "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 a main ASP.NET project which is 64 bit(set to Auto though) and another oracle database project 64 bit(set to Auto). I am getting the above error in "Connection.open()' in the oracle database project. I am using System.Data.Oracle client, the 64 bit version-2.0.50727.5420


Edit.I thought I would mention that I am using the latest Instant Client v 11.0.2.0 from the Oracle to run my program.
....I also tried the ODAC provider from Oracle. Same problem.

Also the oracle database project seems to run fine in x64 bit mode by itself without any problems. The way i verified that it was running in 64 bit mode was I just looked into task manager while the Oracle database project was executing and there was no *32 in the name of the project. All the frame references to this project are already 64 bit. It seems like the issue is the ASP.NET project which is at 3.5

Meanwhile below are things i did to try resolve the issue .

Program Exception On Exit

  
I have written a C# WinForms program that is to run as a scheduled task,  does some file processing and then ends with an FTP session using the scripting version of WS FTP 12.  The program runs fine and completes all tasks including the FTP.  However, when the program terminates, I receive the following .NET Runtime 2.0 Error:   EventType clr20r3, P1 fireeventxfer.exe, P2 1.0.0.0, P3 4c7fb5ce, P4 system.windows.forms, P5 2.0.0.0, P6 4889dee7, P7 14d2, P8 23, P9 system.objectdisposedexception, P10 NIL.   I launch the FTP program using Process.Start(); I have a Process.WaitForExit(); I capture the Process.ExitCode which is always 0; and I Process.Close() call.  I have all of this within a try...catch block, and have never had it throw an error.  I put in a delay for the program to wait 60 seconds after the FTP process exited to make sure it was truly finished, and all that did was delay the error.   I don't believe I have an unhandled exception in the code.  I have gone through the entire program step-by-step, and I have a trace file that captures virtually the entire program execution for almost every line of code.  If I comment out the FTP code, the error does not occur.  The error never occurs until the program exits.  I have an interactive mode that I run the program in that has buttons to start/stop t

I run into the following 2 exceptions when I execute a package on SQL Server 2005 64 bit machine. The package fails when SQL Server version is 9.0.3310 which is a production box. I have tested it on 3 others development boxes with SQL version 9.0.1399, 9.0.3315 & 9.0.4053 and the package executes fine. I am unable to make a determination if this issue is related to SQL versions or a bug in the package design. I would like to understand the exception better before I request an SP3 & patches installed to upgrade it to version 9.0.4053 on the production box.

System.DllNotFoundException when two program load same DLL

  
An exception occurs  in my application,when C# application try load one C++ DLL.  it shows : System.DllNotFoundException: Unable to load DLL (Exception from HRESULT: 0x8007045A) . It's very strange , it's only occurs in such step: 1. A_user  starts one tomcat server,  in one webservice(A_web) of this server use java code "Runtime.getRuntime().exec(a.exe) " to run A program in A_PATH(all need c++ dll in this path)?Call the A_web service, so A program runs and loads all dll. 2?B_user starts B program in B_PATH(all need c++ dll in this path).when it try load dll, it will throw DllNotFoundException. Both A and B are C# program in one PC. A and B can run without error when start in normal way(form cmd). And exchange steps above, run B first and A second, NO exception occurs. It seems that java server adds something on DLL loading. Without such server, all is OK. But what? I use procmon try to find some reason, it shows two difference between two result(right B/wrong B):the wrong one will try twice on get *dll.manifest and *dll.config and failed(the right one try each once and failed);the wrong one don't has ReadFile operation on dll but right one has and succeed. Can anyone give some reason about this?  

Ignore exception made by COM object?

  
Hi, I have third party COM object that I reference into my project. My project was simple console application which source code similar like code below: static void Main(string[] args) { try{ object _comObject = new ComObject(); // do some stuff with _comObject. while (Marshal.ReleaseComObject(_comObject) > 0) { } _comObject = null; } catch { } } I have put try..catch wrap around my Main function and also release COM resources that lock by object. But still COM throw an exception of Invalid Window Handle and made my application to stuck until user click the OK button on error message. Now the problem was why the try..catch not function, if there any exception throw by COM object it should catch by try..catch block. So this point the COM error raised after the try..catch block which mean the exception raised after my application send closed signal to OS. And the bad news is the COM exception is under my application and it made my application stuck (not closed) until the error dialog is closed. I don't want the exception to show up (made my application stuck), that's why I wrap my Main function with try..catch. I just need my application closed. Is there any way to unload the referenced COM library just before application closed (like DllUnload on Native programming), so I can wrap it with try..catch to ignore exception message that made by COM objec

ActivityXamlServices.Load throws exception

  
Hi guys, I have very strange problem and I don't know what to do. I have written application in workflow 4. This application contains a few parts. One of the part is responsible for testing workflow in rehosted workflow designer and another for running workflow periodically. In both parts I use the same code, which is responsible for create Activity from xaml. And here is my problem. In one part this code works fine but in the second part of my application it throws exception. This is the code of which I speak. public static Activity XamlToActivity(Workflow Workflow) { byte[] workflowFilestream = Workflow.FileStream; MemoryStream workflowStream = new MemoryStream(); workflowStream.Write(workflowFilestream, 0, workflowFilestream.Length); return ActivityXamlServices.Load(workflowStream); } Exception Message: "Cannot set unknown member '{http://schemas.microsoft.com/netfx/2009/xaml/activities/presentation}VirtualizedContainerService.HintSize'.' Line number '1' and line position '11'. I'm sure, that xaml is correct (I saved it from workflow designer). It seems to me important thing, that ActivityXamlServices.Load throws exception, when I use it in another Thread (I create new threat, which runs workflows). Someone have any idea or doing something similar? I would be very grateful for help.
