Process.StandardOutput.ReadLine() not "syncing" properly

I've tried to read up on a few articles about this, but some of them were over my head at the moment.

I run a program that re-caches some SQL data from an external source. I call this from a WinForm application which manipulates the aforementioned data.

While the Console app is running, I lay over the controls with a panel (with a textbox on it) and try to capture the Console app's stdout into the textbox. It "works", but has some issues with repe开发者_JS百科ating lines and missing lines. Reading the stream after the process ends works fine, but I'm having issues with real-time.

CODE

It worked well for me in asynchronous way. Unfortunately I'm not so familiar with .net to write code from my memory...

Upd: Spent a couple of minutes and found the page in MSDN. Use Process.BeginOutputReadLine Method, here is the description of the function and a sample of its usage.
