Not sure if anyone else is having this issue.
I am attempting to create a windows forms library control. I need the control to run in an x86 environment. So, the first thing I do is go into the properties of the project and switch the platform target to x86.
I try running the application and I get the lovely error message referencing the assembly I am trying to create and stating: An attempt was made to load a program with an incorrect format.
I have not added any references nor any code, just trying to create a control in x86.
I am using a windows 7 64bit machine with VS2012 trying to write the app in .NET 4.5. I have to do the project in x86 because I am using some OCX that are x86 only.
Has anyone run into this?

Well, that worked. Instead of a confusing COM exception (typically "Class not registered" which has several possible reasons) you get an early .NET exception that tells you that you are using the library wrong.
To test your library project, you needed to create an EXE project that had a reference to the library project. What you forgot to do is change the Platform target setting on that EXE project. Which matters because only the EXE project can determine what the bitness for the process will be. It is the one that loads first, a library project has no say. It can only veto the choice, the BadImageFormatException is that veto.
So you have to change the Platform target setting for the EXE project to x86 as well.

I'm getting this error when trying to install two customization projects. One project is extending a custom page in the other project. There are a few DLL's in play that are being referenced to call web API's. When I Google this error, I get hits for modifying the web.config but, I'm trying to install this in the cloud - acumatica.com
I've tried building all DLLs in x64 but, no dice.
I've got no problems on my local machine. This is only happening on a cloud install.
Any ideas?
TIA!
You might be mixing code that targets different platform (Mixed Platforms). Publishing one customization after the other can help (try both order). When publishing both at the same time it's possible that Any CPU chooses a default platform which isn't compatible with an assembly in the other customization.
Ideally all assemblies (DLL) included in the Files section of your customization project should target the same platform. It is preferred to choose Any CPU platform. Otherwise having only 64 bit assembly could work. If using third party libraries make sure you included the Any CPU version (preferred) or 64 bit version but not the 32 bit version.
You can change platform in the Configuration Manager in Visual Studio:

I have developed an application for Windows CE (Bar Code Scanner Zebra MK500), I make a .cab installer and the installation was correct, but when I try to launch the app, I get this error.:
cannot find 'project' (or one of its components). Make sure the path and filename are correct and that all the required libraries are available.
NOTE: All the dll's are on the installer.
Could be any number of things, but the short of it is that the loader is unable to resolve a DLL that matches both the name and processor you're using.
Check to ensure that all of your directly referenced DLLs exist and they are built for the same processor (since you're using a Zebra scanner, all DLLs must be built for ARM).
Check to ensure indirectly referenced (so DLLs referenced by DLLs you reference) DLLs also exist (like frameworks).
Verify things like runtimes, SQL Server CE native bits - those are the common ones.
I have a Visual C++ library which I want to compile for a certain platform (I try to compile POCO for a Win CE ARM platform, but that might not be relevant to this question). I got a vendor-specific Windows CE SDK (including all common Windows include files e.g. winbase.h) which is set as target platform within the Visual Studio project files. However, when I compile the program, I can see from the error log that the default Windows 6.0A SDK is used, resulting in a bunch of compilation errors.
I guess the WindowsSdkDir ist not set accordingly - I thought this would be automatically overriden when setting the target platform within Visual Studio.
So my question is: can I modify the WindowsSdkDir for a single project explicitly?
Thank you in advance
Which CE version, which VS version and on which Windows version? I know that I had problems installing CE5 and/or CE6 SDKs and getting them recognized by Visual Studio 2005 running on Windows 7 (64 bit). I don't remember the exact symptoms and fix, but you can test that by simply creating a smart device project for the target SDK.
If that is not the issue, there is also the pitfall with the target in both the project file (.vcproj) and the solution (.sln). You can change both independently from each other, up to the point where you compile the x64 debug version of a project in the win32 release version of the solution. Verify that these setting match.
Then, if you adjusted the .vcproj file to use your target platform (for which I personally would use a text editor), things should work. If you need to adjust the build or some paths, you can sometimes get by with e.g $(Platform) in the compiler/linker settings.
Lastly, if all that doesn't work, there are property sheets, which can adjust certain settings. You then create a property sheet once and then load it into the project that you want to compile. I'm not sure if you can change the target platform or the SDK paths with that approach though, and I'd rather try to find out why the SDK doesn't work and how to fix it instead.
I've just recently started working with Visual Studio this summer, primarily on CUDA and OpenCV related projects. Prior to this, I had been doing my development on Linux for CUDA using Makefiles and the common.mk makefile from NVIDIA.
So my question is as follows: I've not been able to figure out for the life of me what the difference between some of the different project templates are. I know that I've had to use "Empty Project" from the general tab of the Visual C++ options, but that's more trial and error, rather than actually knowing what is going on...
A Win32 project is used if you want to end up with a DLL or a Win32 application usually using the bare WinAPI. A common language runtime (CLR) project is used to create C++/CLI project, i.e. to use C++/CLI to target the .NET platform.
The main difference between projects is what Visual Studio comes up with in terms of pre-created files. A windowed Win32 application for example (what you get when you choose Win32 project, but not a DLL) is created with a file for resources (menus, accelerators, icons etc.) and some default code to create and register a window class and to instantiate this window.
When creating a Win32 project, the linker Subsystem is set to Windows. When creating an empty C or C++ project the subsystem is set to console. Likewise the entry point in the settings for Win32 projects expects a WinMain or DllMain while a console expects an int main. A CLR allows you to mix C++ and .NET which is usually discouraged against.
A Windows subsytem can target executables, dlls, libs or driver/native(sys) files. While a console subsystem targets console binary executables. WinMain is typically used when creating an actual Window application using the CreateWindowEx API, establishing message callbacks and inserting a message handler loop.
A console subsustem with int main can also create a Windowed application only you're better off doing it with WinMain.
A Dll empty project sets the subsystem to Windows and setting to the compiled output to (.dll) as well as the entry point to DllMain/APIENTRY and a static lib will do the same as the Dll except it will set the output to (.lib).
Setting the project to Native subsystem will require the Windows Driver Development Kit to compile drivers.
How to include the windows runtime dll files in setup project.
without vc++ 6.0 software in the machine the project must execute.
or give me the hint how to make a the project setup(EXE) in vc++ 6.0 ,i am using create installor,
You can modify the project settings to link statically to the C runtime (I assume this is what you mean when you said windows runtime ?). The static link flags are:
MultiThreaded static linkage (/MT)
MultiThreaded debug static linkage (/MTd)
Sorry, been awhile since I used VC6.0, so I had to check the GUI. You'll find this in project settings, C++ tab, Code Generation combo box, "Use run-time library").
To add to what Cannonade has already said, if you are doing it through Visual Studio, then this can be done through Project Settings->General Page->Use MFC as a static library. This way your created exe will be ready to run on any windows box.
