Hahaha, how can you say it made no changes if now you've only got 2 errors?!

If that's all you're getting, you don't need sdk - in any case, the .net sdk 
wasn't the one I meant.
The Platform SDK would be the one you're after.

Double click on the error you see in the log. It'll take you to those lines 
in the uxtheme.h file.

First is the THEMESIZE structure.

Edit it and format it as follows:

typedef enum THEMESIZE
{
    TS_MIN,             // minimum size
    TS_TRUE,            // size without stretching
    TS_DRAW,            // size that theme mgr will use to draw part
}THEMESIZE;

The second is the PROPERTYORIGIN structure.

Edit it and format it as follows:

typedef enum PROPERTYORIGIN
{
    PO_STATE,           // property was found in the state section
    PO_PART,            // property was found in the part section
    PO_CLASS,           // property was found in the class section
    PO_GLOBAL,          // property was found in [globals] section
    PO_NOTFOUND         // property was not found
} PROPERTYORIGIN;

Save that file and then recompile your project. It should work ok now.

Don't forget to add the 'ThemeManager' component to your main form btw. 
That'll enable proper XP themes in your application and make the others work 
properly (once you've also told them to allow themes via the properties - if 
not enabled by default anyway).
