have you tried this code without making the file?

do MessageBox.Show(filename) inspect the file name to ensure that it is correct. You may be missing an \ between the last directory and filename.

No, I have declared my filename. my text file is in the debug folder, so I put:

In general scenerio, StreamWriter will create new file if it doesn't exist when it is in append mode.

Of course man, and believe me, it creates the text file if it does not exist even I used Append. I'm posting this to confirm from you all as I want all opinions.

I'm new in VB.net that's why I want a confirmation if Append also creates..as many are saying only Create which creates file not Append. Even I have read many articles, they did not mention that Append also creates.

so which type of opinion you want?

Ok, Ankit, if you think this is so in "general" scenario, what do your think of other scenarios?

Well, the solution exist and is very simple, you will find a code sample;

Solution 2

The solution exist: you first create an instance of System.IO.FileStream and then create a System.IO.StreamWriter based on that stream.

The complete code sample is shown here:

I did read this article, I posted this because some people are not believing me that only Append can create a file if it does not exist. It is not necessary to add a Boolean of Create filestream. I just need a confirmation of 'Yes' or 'No' from you that's all. Because on my PC it does create the text file even it does not exist.

Sergey Alexandrovich Kryukov 2-May-11 14:28pm

I don't understand. If "on your PC" something is not created, there is a reason, like user permissions, that's all. This topic is not a matter of experiments; everything should be explained. Now, if you have a appending solution without creations of the stream, I want to see it. StreamWriter does not have append mode indeed. So, please explain.
