Hello Embedded Wizard,
I am using EW 13.02.
I Have a function that tries to combine a error message string. It uses an array of active message id's, finds the corresponding string and either returns an empty string, a string with one message, or a string like "1/3: mess 1 2/3: mess 2 3/2: mess 3"
In this function I use a do ... while (false) construction with a strange result (again)
string GetMessageString()
var string sXOfYSeparator = "/";
var string sNrMessageSeparator = ": ";
var string sMessageSeparator = " ";
array string asShownMessages[3];
var int32 iShownCount = 0;
var int32 iMessageIndex;
var int32 iShownIndex;
var string sShownMessage;
do
{
if (false == MessagesChanged) // class property (boolean)
{
break;
}
CurrentMessage = ""; // class property (string)
MessagesChanged = false;
// 1st: Get max < asShownMessages.size> unique messages
for(iMessageIndex = 0; iMessageIndex < NrOfMessages; iMessageIndex++)
{
var bool bFound = false;
sShownMessage = Application::TheSettings.GetFaultText(Messages[iMessageIndex]); // convert id to string from string table
for(iShownIndex = 0; iShownIndex < iShownCount; iShownIndex++)
{
if (asShownMessages[iShownIndex] == sShownMessage)
{
bFound = true;
}
}
if (false == bFound)
{
asShownMessages[iShownCount] = sShownMessage;
iShownCount++;
}
if(iShownCount == asShownMessages.size)
{
break;
}
}
// 2nd: Create Message string
switch(iShownCount)
{
case 0: CurrentMessage = "";
case 1: CurrentMessage = asShownMessages[0];
default:
{
sShownMessage = "";
for(iShownIndex = 0; iShownIndex < iShownCount; iShownIndex++)
{
if (iShownIndex != 0) sShownMessage = sShownMessage + sMessageSeparator;
sShownMessage = sShownMessage + string(iShownIndex + 1) + sXOfYSeparator + string(iShownCount) + sNrMessageSeparator + asShownMessages[iShownIndex];
}
CurrentMessage = sShownMessage;
}
}
} while(false);
return CurrentMessage;
