    where to start

    now if i clear this first... please dont post any code in this thread, i want to learn the code without being told.

    a project i have just started, will have a open button, so the user can select an npj file. the npj file contains xml data like so

    Code:
    <WAYPOINT_LIST>
    		<ID>8</ID>
    		<NAME>WPList</NAME>
    		<FOLDER>WPList Folder</FOLDER>
    		<MEMBERS></MEMBERS>
    		<COLOR>00000000</COLOR>
    	</WAYPOINT_LIST>
    	<WAYPOINT_LIST>
    		<ID>9</ID>
    		<NAME>WPList</NAME>
    		<FOLDER>WPList Folder</FOLDER>
    		<MEMBERS></MEMBERS>
    		<COLOR>00000000</COLOR>
    	</WAYPOINT_LIST>
    	<AI>
    		<ID>1710</ID>
    		<NAME>[Cindo03] -- Indonesian Civilian #3 Male</NAME>
    		<TYPE_ID>2067</TYPE_ID>
    		<UNSEL_COLOR>FF00</UNSEL_COLOR>
    		<DESCRIPTION>[Cindo03] -- Indonesian Civilian #3 Male</DESCRIPTION>
    		<POSITION>
    			<X>-755.461548</X>
    			<Z>-1422.528076</Z>
    		</POSITION>
    		<TEAM>2</TEAM>
    		<ACCURACY1>75</ACCURACY1>
    		<ACCURACY2>100</ACCURACY2>
    		<FIRE_TIMER>5</FIRE_TIMER>
    		<VISION_RANGE>100</VISION_RANGE>
    		<MIN_ATTACK>0</MIN_ATTACK>
    		<MAX_ATTACK>100</MAX_ATTACK>
    		<ALERT_STATE>2</ALERT_STATE>
    	</AI>
    	<AI>
    		<ID>1711</ID>
    		<NAME>[Cindo03] -- Indonesian Civilian #3 Male (1)</NAME>
    		<TYPE_ID>2067</TYPE_ID>
    		<UNSEL_COLOR>FF00</UNSEL_COLOR>
    		<DESCRIPTION>[Cindo03] -- Indonesian Civilian #3 Male (1)</DESCRIPTION>
    		<POSITION>
    			<X>-760.761108</X>
    			<Z>-1422.518066</Z>
    		</POSITION>
    		<TEAM>2</TEAM>
    		<ACCURACY1>75</ACCURACY1>
    		<ACCURACY2>100</ACCURACY2>
    		<FIRE_TIMER>5</FIRE_TIMER>
    		<VISION_RANGE>100</VISION_RANGE>
    		<MIN_ATTACK>0</MIN_ATTACK>
    		<MAX_ATTACK>100</MAX_ATTACK>
    		<ALERT_STATE>2</ALERT_STATE>
    	</AI>
    now when the user clicks to open the file, i would like a combo box to display the "description" of all of the AI's in the npj file
    eg

    Code:
    [Cindo03] -- Indonesian Civilian #3 Male (1)
    if the user selects the above AI in the list, and then clicks a generate script button, it would output that particular AI's ID. in this case "1711"


    now please dont tell me how to do this, but please could you tell me what i need to go away and revise.. databases? .. to be honest im lost with the whole "open a file and display its contents"

    i know how to create a file by a user clicking a button... if you would need to know what level im at with this to help me, here is a basic program i made

    Do you know how to open a file? If not, google for "ifstream". If yes, sorry, my under-estimation.

    I think you want an xml parser. Have a look at tinyxml.
    or if you're using the .net framework, look at their xml classes, and lookup XPATH queries

    If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?
