c# - Index was outside the bounds of the array (System.Byte to tinyint) -

-

i'm stuck have sp (dbo.getbalance) returns multiple recordsets. 2 recoredsets

and 1 of sp's parameters tinyint ( lang_type ), know in c# system.byte, when i'm trying pass parameter error: "index outside bounds of array"

here code

public class balance : dataclasses1datacontext     {         [function(name = "dbo.getbalance")]         [resulttype(typeof(balanceuserlist))]         [resulttype(typeof(userbalanceaccount))]         public imultipleresults getuserbalance(int iclient_no, int session_id, datetime? bal_date)         {             system.byte lang_type = 0;// helper.getlanguage();             iexecuteresult result = this.executemethodcall(this,                 ((methodinfo)(methodinfo.getcurrentmethod())),                 iclient_no, session_id, bal_date, lang_type );             return (imultipleresults)(result.returnvalue);         }      }

and sp's parameters

@iclient_no         int, @session_id         int, @bal_date           smalldatetime , @lang_type          tinyint = null

what i'm doing wrong?

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
