Post by struccc on Bibliothek: floatingpointutils ^{CODESYS Forge talk (Post)}
The issue s the byte order typically in this case. Can be especially problematic with floating point numbers - even more tricky if transferred with a word based protocol. It is a peasant way to try out the alternatives, dword order can be a-b-c-d, b-a-d-c, c-d-a-b, d-c-b-a where a is the most significant, d is the least significant byte. So all you need is to swap the bytes in your dword, until you get the expected result. If you don't want to mess writing code for this, I'd recommend CAA_Memory library for that: MEM.ReverseBYTEsInDWORD and MEM.ReverseWORDsInDWORD functions would definitively do the trick. Otherwise, can do like this: VAR dwIn : DWORD := 16#11223344; dwOut : DWORD; rOut : REAL; pIN : POINTER TO BYTE; pOUT : POINTER TO BYTE; END_VAR pIN := ADR(dwIn); //pOUt := ADR(dwOut); pOUt := ADR(rOut); pOut[0] := pIN[3]; pOut[1] := pIN[2]; pOut[2] := pIN[1]; pOut[3] := pIN[0]; Ugly, but does the job...

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Post by pistola on C0357: "GetNextClient" is obsolete, use VisuUtils instead ^{CODESYS Forge talk (Post)}
I'm having some troubles with this same issue and I'm wondering if someone can help me out. On a settings visual I allow the operator to enter some values however if they activate the page change button it will change the change with the Numpad dialog open. Since I'm using Visuelems.CURRENTVISU to change the pages I came across this code noted below for determining if the Numpad dialog was active. This code worked great however now in 3.5.19 it's now obsolete. I've tried following the directions in the attached program above however I can't see to get it to work in my program. Can anyone provide some help to determine if a dialog is open? FUNCTION Check_Dialog_Open : Bool VAR_INPUT sDialogName : STRING; // Input variable for the name of the dialog END_VAR VAR pstClientData : POINTER TO VisuElems.VisuStructClientData; // Pointer to the client data structure itfDialogManager : VisuElems.IDialogManager; // Interface for the dialog manager itfMyDialog : VisuElems.IVisualisationDialog; // Interface for the specific visualisation dialog END_VAR // Begin the iteration over the client manager VisuElems.g_ClientManager.BeginIteration(); // Loop through each client until no more clients are found WHILE (pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO // Get the dialog manager interface itfDialogManager := VisuElems.g_VisuManager.GetDialogManager(); // Get the specific dialog interface using the dialog name itfMyDialog := itfDialogManager.GetDialog(sDialogName); // Check if the dialog is open for the current client Check_Dialog_Open := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog, pstClientData, itfDialogManager); // If the dialog is open, exit the loop IF Check_Dialog_Open THEN EXIT; END_IF END_WHILE
