问题 I'm developing a C# application to certify pdf documents.

问题 I converted a perfectly working Managed C++ DLL project that uses Unmanaged C++ LIBs from VS2008 to VS2010. Beforehand I separately rebuilt the LIBs with VS2010 (they are part of another project that I have no authority over).

All errors about "std" entities defined within "string" and "iosfwd" headers. Which compiler/linker settings am I missing? Thanks in

问题 I'm creating an installer for a 3rd Party ActiveX DLL running in IE7-9 on XP-Win7. The MSI should perform the following: Check for admin permissions. Notify the user and exit if insufficient permissions. Check for previous version. If it exists unregister or overwrite it. Install the DLL with vsdrfCOM so that it is recognized in the IE add-on menu. For (3), I set the vsdrfCOM but it didn't seem to work. I don't see an OOTB way to perform (1) or (2). Is that correct or is there an OOTB way?

问题 I have a Visual Studio project that references an assembly that I also created. Below is a screen shot of the properties of my assembly reference in the project. When I update my assembly version to 1.1.0.0 , my project fails, and I am thinking this property is the issue. Since the Version attribute says 1.0.0.0 , does this mean it will always look for my assembly that has a version of 1.0.0.0 ? And incrementing my version to 1.1.0.0 will cause my project to not see the assembly at all? 回答1:
