Copying file error.

asma_panjabi

Hi m trying to copy image file from one location to other as below in openDialog box C#.net

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string filename = System.IO.Path.GetFileName(openFileDialog1.FileName);

      string fname = Application.StartupPath + "\\\\Temp\\\\" + filename;
            File.Copy(openFileDialog1.FileName, fname, true);

}

I get Exception as Unknown software Exception(0xe0434f4d) ocurred in application at location 0x7c59bcb1 It works for all files except for .bmp file Ne help for it?

You should trap the exception in a Try Catch block and see what the actual error is. That exception's generic and it could be anything.

I don't see anything obviously wrong, so the next step should be to get more information about the bug. See what the values are for OpenFileDialog.FileName and fname. If they look ok, put a try/catch around this, and display the message on the exception.

Hi, did you bother looking at the values of filename and fname? IIRC OpenFileDialog.FileName returns a file path, so your fname would be garbage. FYI: (sub)folders of a StartupPath may be write-protected. You should consider using Environment.GetFolderPath() :)

I have trapped the exception in try catch block.

I have debugged the code i get proper values in filename and fname

More of a FYI than an answer , but you should always put the checked for value first:

if (DialogResult.OK == openFileDialog1.ShowDialog())
{
string filename = System.IO.Path.GetFileName(openFileDialog1.FileName);
string fname = Application.StartupPath + "\\Temp\\" + filename;
File.Copy(openFileDialog1.FileName, fname, true);
}

that way if you mess up and only type one = you'll get an error during compile. This show what I mean:

int num = 3;
if (num = 4)
{
//num will be equal to 4 and this block always executes
}

vs

int num = 3;
if (4 = num)
{
//You could never build this file without an error because you can't assign to an int value
}

And if you try another .bmp, same effect? Maybe the BMP is malformed or something. Does the Temp directory exists?

The exception has a Message member. What is the message when you get this exception?

asma_panjabi

Other bmp files work properly even the temp folder exists only some bmp files dnt work
