how do I fix a sentence filter issue using toupper and tolower in output file

Question

I had a question about how to fix this code I have where I'm trying to go through and make everything lowercase then every first letter of a sentence - the one after a period space - uppercase. I'm doing something wrong, but I cannot figure out where I went wrong. My code hangs after creating the output file sucessfully. Why does my code hang? How can I fix it?

#include <iostream>
#include <fstream>
#include <string>
#include <cctype>
using namespace std;

class Test
{
private:
    string fileIn;
    string fileOut;
    char ch;

    ifstream inFile;        //input file stream
    fstream outFile;        //output file stream
public:
    Test();         //constructor
    void getData();
    void testOpen();
    void validate();
    void outOpen();
    void transform();
    void close();
};

}

void Test::getData()
{
    cout << "Enter the input file name including file type and hit enter when finished." << endl << endl;
    getline(cin, fileIn);

    cout << "Enter an output file name including file type and hit enter when finished." << endl << endl;
    getline(cin, fileOut);
}

void Test::testOpen()
{
    inFile.open(fileIn);

    validate();
}

void Test::validate()
{
    if (!inFile)
    {
        cout << "The file could not be opened.";
        exit(1234);
    }
}

void Test::outOpen()
{
    outFile.open(fileOut, ios::out);
}

void Test::transform()
{
    //set all letters to lower case
    inFile.get(ch);
    while (!inFile.eof())
    {
        outFile.put(tolower(ch));
        inFile.get(ch);
    }

    //rewind to beginning
    inFile.seekg(0L, ios::beg);

    //make all letters after .space upper case
    inFile.get(ch);
    while (!inFile.eof())
    {
        if (inFile, fileIn, '. ')
        {
            inFile.get(ch);
            outFile.put(toupper(ch));

        }
    }
}

void Test::close()
{
    inFile.close();
    outFile.close();
}
