Winrunner - File Handling

Winrunner code is similar to 'C' code. Any automation suite must have file handling functions for various scenarios. It may be just text files or any data files. Winrunner also has few methods for file handling. Below few sample code snippets are given..

Code: To read a file

#---------------------------------
# Method : fileRead 
# Author : T.Palani Selvam
# Purpose : Read all contents of a file.  
# Parameters: String, contains file name.
#    
# Returns :   - Nil -
# Caller : 
# Calls  : - Nil -
#----------------------------------
public function fileRead(in m_sFile) {
auto iLine;
auto sEachLine;
auto sFileContent;

printf("fileRead is going to process for " & m_sFile);
file_open(m_sFile,FO_MODE_READ);
iLine = 0;
while(file_getline(m_sFile, sEachLine) == 0) {
sFileContent = sFileContent & sEachLine;
iLine++; 
printf(sEachLine);
}
#report_msg(sFileContent);  #Line is too length
file_close(m_sFile);
} #end of fileRead(in m_sFile)

Code: To write info to a file

#------------------------------
# Method : fileWrite 
# Author : T.Palani Selvam
# Purpose : Write Given inputs to a file.  
# Parameters: String, contains file name.
#    
# Returns :   - Nil -
# Caller : 
# Calls  : - Nil -
#-----------------------------
public function fileWrite(inout m_sFile) {
auto iLine;
auto sEachLine;
auto iBool;
auto null="";

printf("fileWrite is going to process for " & m_sFile);
file_open(m_sFile, FO_MODE_WRITE);
iLine = 0;
do {
sEachLine = create_input_dialog("Enter Input to write in " & m_sFile);
if (sEachLine == null ) { #equals to NULL
iBool = 0;
}
else {
iBool = 1;  
iLine = iLine + 1;
file_printf(m_sFile,"%s",sEachLine & "\r\n");
printf(sEachLine);
}

} while(iBool == 1);
file_close(m_sFile); #Closing file

} #end of fileWrite(in m_sFile)

Code: To Append info to a file

#-----------------------------------
# Method : fileAppend 
# Author : T.Palani Selvam
# Purpose : Write Given inputs to a file.  
# Parameters: String, contains file name.
#    
# Returns :   - Nil -
# Caller : 
# Calls  : - Nil -
#----------------------------------
public function fileAppend(inout m_sFile) {
auto iLine;
auto sEachLine;
auto iBool;
auto null="";

printf("fileAppend is going to process for " & m_sFile);

file_open(m_sFile, FO_MODE_APPEND);
iLine = 0;
do {
sEachLine = create_input_dialog("Enter value to append in " & m_sFile);
if (sEachLine == null ) {  #equals to NULL
iBool =0;
} else {
iBool = 1;
iLine = iLine + 1;  
file_printf(m_sFile,"%s",sEachLine & "\r\n");
printf(sEachLine);  

}
} while(iBool == 1);
file_close(m_sFile);

}   #end of fileAppend(in m_sFile)
