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 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.

Update: I was able to successfully use the SysCom.lib. I had to install SysTypes2Interface library as well and wrote following code. Declaration hCom : RTS_IEC_HANDLE; pResult : POINTER TO RTS_IEC_RESULT; Implementation hCom := SysComOpen(ComSettings.sPort, ADR(pResult));

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by trusty-squire on Help with __SYSTEM.VAR_INFO ^{CODESYS Forge talk (Post)}
Not knowing exactly what you want to accomplish, you can try to use VAR_INPUT MyVar: POINTER TO BOOL; END_VAR MyVar contains the address of your referenced variable, and MyVar^ dereferences it allowing you to access the value. If this doesn't meet your needs, could you add more detail on what you are trying to accomplish?

I'm having trouble getting started with the SysFile library. I tried copying and running the code found here: https://forge.codesys.com/forge/talk/Engineering/thread/f17c3d0e64/ Every time I try to run the file handle pointer returns: 16#FFFFFFFFFFFFFFFF <dereference of="" invalid="" pointer=""></dereference> I can see the file when I look in the Device -> Files window Any idea what I'm doing wrong?
