vsz wizard create solution

Hey,

I'm working with a custom wizard and wanted to know if it is possible to create a solution in a different folder than the .vcxproj-file.

prj = oTarget.AddFromTemplate(strProjTemplate, strProjectPath + "\\" + strProjectName + ".dll", strProjectNameWithExt);

This line creates a new solution, if no solution is opened. But I don't know how to change the path of the solution or if it's even possible to create a solution in a different path than the vcxproj file. I made some tries with wizard.FindSymbol('Target') but didn't find a solution. 

Could you point me how this could work?

Thanks in advance!
