Actually i am using the AsyncCalls library to execute an Query asynchronously in this way.

       while AsyncMultiSync([RunQuery], True, 10) = WAIT_TIMEOUT do
       begin
            FrmProgress.refresh; //Update the ellapsed time in a popup form
            Application.ProcessMessages; 
       end;

and everything works ok.

Now i want to do the same for load the query in a grid.

so i tried this

         while LocalAsyncVclCall(@InitGrid, 10) = WAIT_TIMEOUT do
         begin
              FrmProgress.refresh;
              Application.ProcessMessages;
         end;

but obviously not compile because the type returned by LocalAsyncVclCall is IAsyncCall and not a Cardinal.

also i tried this, but not works.

             while not LocalAsyncVclCall(@InitGrid, 10).Finished do
             begin
                  FrmProgress.refresh;
                  Application.ProcessMessages;
             end;

How i can use LocalAsyncVclCall or another function to execute an VCL code asynchronously .

i want something like this.

             while ExecuteMyVCLProcedure(@InitGrid) = WAIT_TIMEOUT do
             begin
                  FrmProgress.refresh;
                  Application.ProcessMessages;
             end;

Thanks in advance.
