Post by gatto on Read codesys version in the codesys application ^{CODESYS Forge talk (Post)}
hi, i used another way declaration: pApp : POINTER TO APPLICATION; pAppInfo : POINTER TO APPLICATION_INFO; ProjectName : STRING (24) ; CodesysVersion : STRING (15) ; code: //library : // CmpApp // IoDrvEthernet // // Get Pointer to current application pApp := CmpApp.AppGetCurrent( pResult:= 0 ); // Get Pointer to Application information pAppInfo := CmpApp.AppGetApplicationInfo(pApp:= pApp, pResult:= 0 ); ProjectName := pAppInfo^.pstProjectName^ ; //convert codesys version to string CodesysVersion := IoDrvEthernet.UDINT_TO_IPSTRING ( udiIPAddress := pApp^.udiPSVersion ) ; so i think you need to convert your dwVersion in a UDINT and after convert UDINT_TO_IPSTRING

First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Post by davemansell on explicit cast ENUM to UINT and vice versa ^{CODESYS Forge talk (Post)}
This is from sometime ago but below might help someone else; this could be done via POINTERS. Make sure you protect for NULL pointers etc if you take this approach. // DECLARATION myEnumValue : enumMyEnum; u8 : USINT; pmyEnumValue : POINTER TO enumMyEnum; pu8 : POINTER TO USINT; // CODE pu8 := ADR(u8); pmyEnumValue := pu8; myEnumValue := pmyEnumValue^; // dereference the pointer

Now that SP21 is out, what's the answer? I want to get a pointer to the TxPDO and RxPDO structs. I can generate a STRUCT declaration from the ESI file with a bit of Python. I just need to get the pointer from the ETC_Slave.

Post by pistola on Pause Tab Order ^{CODESYS Forge talk (Post)}
I'm programming an HMI, and on a settings page I have external buttons allow the operator to tab between various elements to select which one they want to adjust. I then use "Input Configuration" > "OnMouseClick" to select which variable to adjust. The problem is, when adjusting the variable the pointer will move to the other elements within the tab order. Is there a way to pause or prevent the pointer to move to the other elements when a variable is TRUE?

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

Post by remcoborghuis on C0032 Error to type Pointer to IoConfigParameter ^{CODESYS Forge talk (Post)}
Hi All, I'm using codesys on a raspberry PI. I use V3.5 SP18 Patch 2 development system and codesys for raspberry pi 4.8.0.0. Sometimes when I build the project I get error messages C0007: Expression expected instead of ',' and C0032: Cannot convert type 'Unknow type: '!!!'ERROR'!!!" to type 'POINTER TO IoConfigParameter'. I can't click on the message to bring me to the fault. After I do a "Clean all" the build finishes successful. Anyone who can help me with this problem? Thanks! Remco Borghuis

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.
