Writing to file

[Clement Chand C S]

Hi friends,

int filehandle0l=FileOpen(File_Name1,FILE_TXT|FILE_WRITE|FILE_READ|FILE_SHARE_READ); 
                  if(filehandle0l!=INVALID_HANDLE) 
                  { 
                    FileSeek(filehandle0l,0,SEEK_END);
                    FileWrite(filehandle0l,"a");
                    FileClose(filehandle0l); 
                  } 

the above code give me the result as follows

a

But I need the result as follows

string text = "aaaaaaaaaaaaaaaaaaaa";

int filehandle0l=FileOpen(File_Name1,FILE_TXT|FILE_WRITE|FILE_READ|FILE_SHARE_READ); 
                  if(filehandle0l!=INVALID_HANDLE) 
                  { 
                    FileSeek(filehandle0l,0,SEEK_END);
                    FileWrite(filehandle0l,text,StringLen(text));
                    FileClose(filehandle0l); 
                  }

I cannot already define string text like you defined. It is generated by some conditions.

Then open the file with FILE_BIN and use FileWriteInteger with CHAR_VALUE flag.

Build your string before writing to the file then?

// build string however you do it
for(int i=0;i<5;i++)
  tx+="a";

 int filehandle0l=FileOpen(filename,FILE_TXT|FILE_WRITE|FILE_READ); 
 FileSeek(filehandle0l,0,SEEK_END);
 FileWrite(filehandle0l,tx);
 FileClose(filehandle0l);

hi do you mean as follows?

if(condition)
                 {
                
                  int filehandle0l=FileOpen("File_Name1.bin",FILE_BIN|FILE_WRITE|FILE_READ|FILE_SHARE_READ); 
                  if(filehandle0l!=INVALID_HANDLE) 
                  { 
                    FileSeek(filehandle0l,0,SEEK_END);
                    FileWriteInteger(filehandle0l,"a",CHAR_VALUE);
                    FileClose(filehandle0l); 
                    
                    
                  } 

if so i am getting the result as

Please have a look at

for()

{


if(condition)
                 {
                
                  int filehandle0l=FileOpen(File_Name1,FILE_TXT|FILE_WRITE|FILE_READ|FILE_SHARE_READ);

                    FileWrite(filehandle0l,"l");
                    FileClose(filehandle0l); 
                    
                    
                  }

}

depending on conditions this may give the result as

r
l
k
b
k
k
r
l

but i need the result as

rlkbkkrl

Pls help. thank you.

It's because a new line character \n will be automatically added.

FileWrite

The function is intended for writing of data into a CSV file, delimiter being inserted automatically unless it is equal to 0. 

After writing into the file, the line end character "\r\n" will be added.

In your case that is undesirably because it will put every new entry on a new line.

In stead you want to write a function that appends your data to the same line until you manually add a \n new line chr.

Please mind double quotes around the letter (a) are changed to single quote. "a" -> 'a'
