System.Badimageformatexception Error Under VS2010

Hello,

Under VS2010 on a Win7 64pro box I am getting an error when I try to compile the examples. I am using the C# examples and adding the reference to EZ_B.DLL but when I go to run the example I get an "System.BadImageFormatException was unhandled" error and the application will not run.

I have tried changing the .NET frame work version from "4.0" to "3.5" and "2.0" without any effect. I have also tried changing the platform from "any CPU" to "x86" also with no effect.

What else could I try?

Full error below System.BadImageFormatException was unhandled Message=Could not load file or assembly 'EZ_B, Version=2011.6.28.0, Culture=neutral, PublicKeyToken=839146fd54f35ea1' or one of its dependencies.

Interesting! I haven't seen that before. Let me take a quick look and see if I can replicate it

Bump.

Were you able to replicate the issue?

I have been able to replicate this issue on VS2010 express and on a second box using VS2010Pro. Both box's running Win7x64.

Has anyone compiled under VS2010 on Win7x64 ?

Sadly I haven't been able to replicate this. I don't know what's causing it for you. Have you followed the directions on the readme.txt about what other libraries need to be installed?

Hi, I have the same problem on Windows 7 64 bit edition. I tired the same code on my Windows 7 32 bit edition machine and it get farther. Now I get the "LoaderLock" error. I have been looking all over the forum for the solution but so far I have not found anything. I'll let you know if I find anything. Nelson

Update: Found the loader lock information in the SDK Readme. It works on Windows 7 32 bit edition but not 64 bit edition. The 64 bit edition is having problems with the EZ-B.DLL.

Update 2: Found the workaround... Open the project and change the Platform Target to x86. Also change your build configuration to use x86. You will probably also encounter the loader loack issue. If you do go to the "Debug"/"Expceptions" enlarge the "Managed Debugging Assistants" and uncheck the "LoaderLock" box.

I've run into this too, and the workaround isn't working for me (win7 64 bit, running VS2010 SP1). Kinda sucks, I had my eye on a nice bot to modernize:(

Any big reason why it's not possible to just include an amd64 version of EZ_B.dll in the SDK? I don't think you need to be running 64 bit windows to build a 64 bit dll...

Edit: Oh, I figured it out! I need to set the type to x86 in the configuration manager (Build menu -> Configuration Manager... -> Active Solution Platform). Now I also get the OS Loader Lock error, but the readme has the solution for that.

@faybs good to hear you got it working. In step 7 of the read me it states

Quote:

7) Projects must be compiled as x86 (not 64 bit). Configure your project to generate x86 (32 bit) binaries. Right click on project, select Build and change the CPU to x86

x86 is faster than x64 for the type of processing and datatypes that I use. There is no benefit to releasing a x64 DLL, it would be slower.:)
