Dear 

I wrote a code below to delete all object match with object name

void DeleteObject(string OJ_Name)
{
   string OJ; bool is_Delete;
   for (int i = ObjectsTotal(0)-1; i >=0; i--) {
      OJ = ObjectName(0,i);
      if (StringFind(OJ, OJ_Name) >= 0) {
         is_Delete = ObjectDelete(0,OJ);
      }
   } 
}

Some time it compile ok some it give error and want to not compile


But as my knowledge code doesn't have any problem.

From the error, I assume you are compiling under MQL4 because there are two variants on using the OrdersTotal() function, so you will have to qualify it and use one of the two alternatives:

   ...
ObjectsTotal( (long) 0 )  // Make it a long and not an int
   ...
ObjectsTotal( 0, -1, -1 ) // Or add the extra parameters
   ...
ObjectsTotal()            // Or just use the other variant
   ...

ObjectsTotal

( https://www.mql5.com/en/docs/objects/objectstotal )

The function returns the number of objects of the specified type in the specified chart. There are two variants of the function:

int  ObjectsTotal(
   long  chart_id,          // chart identifier
   int   sub_window=-1,     // window index
   int   type=-1            // object type
   );

The function returns the number of objects of the specified type:

int  ObjectsTotal(
   int    type=EMPTY        // object type
   );

When this function is used on the current chart, this chart is accessed directly, while in order to receive the properties of an object on a different chart, a synchronous call is used. The synchronous...

If an empty string is specified as the prefix, objects with all possible names will be removed. The function uses a synchronous call...
