Dear Support Board I have a study where 2 values are updated via ACS Buttons. I want to retain the 2 updated study values from every chart in my chartbook that has this study loaded - so when they are reopened the last values/settings can be used. Int Parameter_1 = 5; Parameter_2 = 6; I’ve read through the threads and manual and sc.StorageBlock which seems to be the solution, however I can’t find any examples of where to place the different items of code. // ------------------------------------------------------ // Is this correct? // ------------------------------------------------------ // Part 1 - Is this placed in the default block? // This is the structure of our data that is to be stored in the storage block. struct s_PermData { int i_Parammeter1_Stored; int i_Parammeter2_Stored; }; // Part 2 - Then in the do processing section where the changes are made // Using the sc.StorageBlock // After updating the values: Parameter_1 = 11; Parameter_2 = 12; // Here we make a pointer to the storage block as if it was a pointer to our structure // Where is this placed? s_PermData* PermData; PermData = (s_PermData*)sc.StorageBlock; // Here we set data using the members of our structure. This uses the memory of the storage block PermData-> i_Parammeter1_Stored = Parameter_1; PermData-> i_Parammeter2_Stored = Parameter_2; 2 additional questions re the above: - When a chart or chartbook is deleted is the Storage Block automatically deleted or released? - I have 10 charts in a Chartbook and 3 Chartbooks in my chartbook group. Each chart has this study. Will each chart save to its own Storage Block? Apologies for a long-winded thread but Storage blocks are a little beyond my ACSIL knowledge. Any help appreciated Many thanks. |
