Using Microsoft Visual Studio Debugger for User-Defined Functions

These steps will give the Microsoft Visual Studio 2008 developers the ability to step through the user-defined functions code.

Attach the debugger to a running server:

devenv /debugexe "%IQDIR15%\bin32\iqsrv15.exe"

Goto Debug | Attach to Process
To start the server and debugger together:
```
devenv /debugexe "%IQDIR15%\bin32\iqsrv15.exe" [commandline options for your server]
```
Each platform will have a debugger and each will have their own command line syntax. Sybase IQ source code is not required. The msvs debugger will recognize when the user-defined functions source is executed and break at the set breakpoints. When control returns from the user-defined functions to the server, you will only see machine code.
