[req]Everything Search IPC C# demo code?

[mazzzzz]

Hey guys, I guess the title says it all. I code in C#, and was wondering if anyone could provide some demo code that would retrieve results from the everything index??

Thanks,
Max

David,

I downloaded the Search Everything SDK. When I run the C# sample I get the following error after I enter search criteria and press the search button:

Any thoughts on what I am doing wrong?

Are you trying to compile your project for the x64 platform target?
The everything.dll is only 32bit.

[sbraun]

Thanks David.

I am running a Windows 7 64bit OS... the Build:Platform Target was set to Any. I changed it to x86, compiled and ran the sample with no problem.

Thanks again, Everything Search is a great piece of work.

David,
The above Code Works fine but i want to search file in Network share folder.please give a acceptable solution.
Thanks in Advance

I'm able to build an run the C# demo code (thanks to this thread) and I get results but they aren't correct. See screenshot comparing concurrently running demo code and Everything native app. Note that the same search term was used but different result counts were reported as well as vastly different results. I'm guessing the input is getting mangled in my searches, but I wanted to post in case anybody has seen this or understands it better than I.
Thanks for any help you can provide.

NEVERMIND

I manually edited the call to Everything_SetSearch() to be Everything_SetSearchW() for test purposes and forgot to change it back. I'll leave this here in case anybody else makes the same dumb mistake.

I realized this by noticing that any search term with an ODD number of characters returned 0 results and a term with EVEN characters returned results, but they were incorrect results. It does work perfectly, as expected.

Thanks a lot, David!
