Hi, I following this document to debug a module:

http://www.dnnsoftware.com/community-blog/cid/155087/debugging-a-dnn-module

Nothing error. But it seems not the updated module. I am sure the DLLs/PDBs under BIN of website is replaced with new version.  I make some changes on the ASCX file. Do I need to move the ASCX files to website as well? 

So stupid I am....get it work now, thanks alot.

By the way ,there is strainge problem comes up.

I build release version also change web.config to release. Then intall by Host panel. Then add it to a page. It comes up error as below:

 Then funny thing coming, if I build the module again(I already set the build path to BIN of website), refresh the page, Everything shows up right as below.

That means my code is correct. I double check codes many times. Pretty sure there is no error.

It is just some simple codes that getting values from two fields(folder, filename) of table [files]. This table is built-in DNN NOT mine.

I debug these two variables values are correct. I don't know how come it gets this error. SQL string is

select [Filename],[Folder] as Fds from [files] where fileid=208  (there is  record )

I am using repeater showing the images in ascx file. (DataBinder. Container.DataItem,"Fds"))

I find the problem is from the field "folder". If I dont use "folder" field, everything is fine. If I use field "folder", error shows up as first screen shot above.

Could it be a little bug of your platform? Or anything else causes this?
