Hi,

I find a lot and finally make a solution which is correct or not i dont know.

You need to create a custom action and need to map this function to this custom action.

export prototype PopulateListCombo(HWND); 
//PopulateCombo
function PopulateListCombo(hMSI)  
   LIST  StringList;
   STRING svString, sPath;
   NUMBER nResult, nPath;  
   NUMBER hDatabase, hCBOView, hView, hRec;
   STRING szText;  
   number index, nCount;
   STRING sQuery;
begin      
	index=0;
	hDatabase=MsiGetActiveDatabase(hMSI);
	
	sQuery="SELECT * FROM ComboBox WHERE Property='PROPNAME'";
	nResult = MsiDatabaseOpenView(hDatabase,sQuery,hCBOView);
	hRec=MsiCreateRecord(4);
	
	StringList = ListCreate (STRINGLIST);
	ListAddString(StringList,"ZAQ",AFTER);   
	ListAddString(StringList,"FAK",AFTER);
	ListAddString(StringList,"MAM",AFTER); 
	
	nResult = ListGetFirstString (StringList, svString);                      
	MsiRecordSetString(hRec,1,'TESTPROP');
	MsiRecordSetInteger(hRec,2,index);
	MsiRecordSetString(hRec,3,svString);
	MsiRecordSetString(hRec,4,svString);
	
	MsiViewModify(hCBOView,MSIMODIFY_INSERT_TEMPORARY,hRec);
	nResult = ListGetNextString (StringList, svString);
	
	while (nResult != END_OF_LIST)
		index=index+1;
		MsiRecordSetString(hRec,1,'TESTPROP');
		MsiRecordSetInteger(hRec,2,index);
		MsiRecordSetString(hRec,3,svString);
		MsiRecordSetString(hRec,4,svString);
	
		MsiViewModify(hCBOView,MSIMODIFY_INSERT_TEMPORARY,hRec);  
	    nResult = ListGetNextString (StringList, svString);      
	endwhile;
	
	MsiCloseHandle(hRec);
	MsiViewClose (hView);
end;

Remember to put your combo box Property name in to this line, Instead of TESTPROP.

MsiRecordSetString(hRec,1,'TESTPROP');;

I hope this will save some of your time.

I have got a case where i need to remove my combobox item during runtime. Is there a way where i can do it? I have been struggling to get this work from many days

Use case:

I have got a combobox and i have selected one item from it to do some customaction. In the next dialog i want the combobox item to get removed because i have already used it. So the remaining items needs to show apart from the one i have selected in the previous dialog. 

Is there any piece of code which can make this work ?

Any help is highly appreciated .
