openFileDialog problem

[Cory]

I have a very strange problem with my C# code. I trying to
add a file to my dataset. I use a openFileDialog object to
get my file. I put the file pathname in a textbox. Then i
click my upload button which adds my file to the dataset
and then writes the dataset to a XML file(ds.writeXML
("test.xml");).I know the file is added to the dataset but
it doesn't get written to the XML file. The strange thing
is if i type the file pathname in the textbox it works
perfect.Any help would be appreciated.

Thanks in advance

Cory,

Can you show some of your code? Assuming that the dialog will update the textbox correctly, there should be no difference. Are you sure that the contents of the textbox are the same either way?

This is the code in question

//browse button
private void cmdBrowse_Click(object sender, System.EventArgs e)
{
if(openFileDialog1.ShowDialog(this) == DialogResult.OK)
{
txtFileName.Text=openFileDialog1.FileName;
}
}
//upload button
private void button1_Click(object sender, System.EventArgs e)
{
String fileName = txtFileName.Text;

if(fileName.Equals(""))
{
MessageBox.Show("File Name cannot be blank");
txtFileName.Select();
txtFileName.Focus();
}
else
{

//Get the fileData
string fileData="";
FileInfo fi= new FileInfo(fileName);
FileStream fs=fi.OpenRead();
int nBytes=(int)fi.Length;
byte[] ByteArray=new byte[nBytes];
int nBytesRead=fs.Read(ByteArray, 0, nBytes);
fs.Close();
fileData=Convert.ToBase64String(ByteArray);
CSupFile mySupFile=new CSupFile();
mySupFile.setAuditID(auditId);
mySupFile.setAuditDate(auditdate);

mySupFile.setType("b");
mySupFile.setSupData(fileData);
if(mySupFile.saveFile(data)==true)
{
this.Close();

}
else
{
MessageBox.Show("Supporting document could not be saved. Please try
again.");
}
}
}
