由 霸气de小男生 提交于 2019-11-27 14:11:38
问题 My goal is to add macros to an excel workbook without having to enable "Trust Access to the VBA Project Object Module" in the Excel Trust Center. (Enabling access seems a security risk). Found random pieces of puzzle on my initial fact finding search: -I see that VBA script is stored in the zipped .xlsm file as vbaProject.bin. -There are several free/commercial resources that can work with excel files: Create excel without interop and template with or without row and columnspan It would be

Registering COM referenced DLLs on a build server

由 与世无争的帅哥 提交于 2019-11-27 14:08:43
问题 We're developing a C# application that references a few COM libraries (AutoIT for example). I am including all referenced components under source control, in a 3rd party "Libs" folder. The problem is that COM dll's don't have a HintPath property in the .csproj file, and i assume these must be manually registered using regsvr32 (or using a script of some sort). I am currently looking into creating an MSBuild script that will run before every build, however i couldn't figure out if i should be

Often it is happening by period, then disappear. It seems that some of them are created by load balancers such as this example: NetScaler Appliance. Do you know any other instances of

Java and C# interoperability

问题 I have two programs. One is in C# and another one in Java. Those programs will, most probably, always run on the same machine. What would be the best way to let them talk to each other? So, to clarify the problem: This is a personal project (so professional/costly libraries are a no go). The message volume is low, there will be about 1 to 2 messages per second. The messages are small, a few primitive types should do the trick. I would like to keep the complexity low. The java application is
