Hi, I have an MFC application for which I have integrated OPC function using Wintech OPC DLL. This application is an OPC Client which connects to a OPC Server and gets values from it using OPC communication. I call the OPC functions in my application. I used WPF(dll created by C#) in this application for some graphics and turned on the project setting "Common Language Runtime Support (/clr)" When I run my application in VS2008 using F5, it runs without any issues it shows correct values. But when I run the same application using Cntrl+F5 or directly run the EXE, it runs but it shows junk values. Notes Suppose i change project setting from "Common Language Runtime Support (/clr)" to "No Common Language Runtime support" it is not supported WPF dll. Please help me to find the solution for this problem

Hi, Am trying to connect WinTECH OPC Client to MaxDNA V6.0.7 server in local PC and LAN network also. These Connection was successfully established but it was showed "Tag Quality bad" and "Value Unspecified Error". How to solve this issue please help me ASAP.

The same code works fine in VS2008. And moreover the issue occurs when I try to initialize the union member before actually sending the data to the socket. My question is why I am not able to assign a float value to the union member which is also a float variable. This same line of code assigns the value in VS2008. Why its not doing it in VS2017

UNI.S.fTestValue1 = fTest; //6.360e-39#DEN // Junk value - Wrong
UNI.S.fTestValue2 = 190.000015f; //1.401e-45#DEN // Junk value - Wrong

float fLocalValue;
float fTest;

fTest 		        = 190.000015f;

fLocalValue	        = fTest;   		//190.000015    //Correct value
UNI.S.cChr 	        = 'c';			//'Ô'           //Junk value - Wrong
UNI.S.fTestValue1 	= fTest;		//6.360e-39#DEN //Junk value - Wrong
UNI.S.fTestValue2 	= 190.000015f;		//1.401e-45#DEN //Junk value - Wrong

Output 190.000015 - Correct value 'Ô' - Junk value - Wrong 6.360e-39#DEN - Junk value - Wrong 1.401e-45#DEN - Junk value - Wrong

Hi, I have a server client application using TCP/IP sockets in MFC VS2017. Originally i have written the code in VS2008. Kindly see the below code which sends the data to client. But this same code gives me some problem in MFC VS2017. In the below code when I assign the value 190.000015f to a local variable, its taking the value whereas when I assign it to the union member variable

UNI.S.fTestValue1

and

UNI.S.fTestValue2

it showing some junk value. Please help me to fix the problem

unsigned char* CSendValue :: SendLiveValues()
{
union USendLive
{
struct SSend
{
float fTestValue1;
float fTestValue2;
char cChr;
}S;
unsigned char Buffer[LIVEUNISIZE];
}UNI;

memset(UNI.Buffer,0,LIVEUNISIZE);

float fLocalValue;
float fTest;

fTest 		        = 190.000015f;

fLocalValue	        = fTest;   		//190.000015    // Correct value
UNI.S.cChr 	        = 'c';			//'Ô'           // Junk value - Wrong
UNI.S.fTestValue1 	= fTest;		//6.360e-39#DEN // Junk value - Wrong
UNI.S.fTestValue2 	= 190.000015f;		//1.401e-45#DEN // Junk value - Wrong

    return UNI.Buffer;
