Assign new symbology to a directory of files

George Chandeep Corea

I haven't used GMS in over an year and I just need to do the following

Cycle through directory for tab files (mapinfo)
assign the symbology (for example)

GM_TYPE=Contour
LINE_WIDTH=2
LINE_COLOR=RGB(128,64,0)
LINE_STYLE=Solid

How do I select by attribute? how do I then set the above for each attribute type?

You can use DIR_LOOP_START and DIR_LOOP_END to cycle through your directory.  For each file in the directory, you will need to IMPORT it, then run EDIT_VECTOR and EXPORT commands to produce the updated file.  On your EDIT_VECTOR command, use the COMPARE_STR parameter to select by attribute, and ATTR_VAL and STYLE_ATTR parameters to set your style attributes.

The scripting reference is here.

Thanks. The symbology works fine but I am getting projection issues. The output data does not open in the same space as the original when the files are opened in mapinfo. It is fine in GM when I define the projection on opening the files. Is something in my code creating this issue. It is fine when I manually update the style and export the file.

Also how do I delete the extra GM_Layer field that's created?
