Problem with C# multiline textbox memory usage -

Problem with C# multiline textbox memory usage -

I am using a multilingual text box in C # to log some trace information. I just need to add the line as the appendex (using "text-goes \ r \ n") .

I have run this program for a few days (with a lot of active trace) and I saw that it was using very much memory, short story short, it appears that the maximum outstanding value ( 256) is expanded with the extension of the contents of the text box.

I thought it works like a FIFO (throwing oldest text is more than the maximum length size). Not so, it just keeps on growing in size. This is apparently the reason for my collection of waste. Anybody know what I am doing wrong?

  Added a few hours after the initial question ... Okay, I tried the code suggested below. To test it quickly, I just add the timer to my app and that timer, now I call a method which essentially does the same thing as the code below, so the tick rate is high so that the process I can see the memory usage and can quickly determine whether there is leakage. There was not that was nice; However, I put it in my application and there was no change in memory usage (still leaking). It is sure that I think that there is a leak somwehere and :-( However, if I just add a return on top of that method, the usage goes back to stabilize. Any ideas on this? Timer Tic-accumulated memory Does not, but my real code (the same way) does. The difference is that I am calling the method from many different places in the actual code. Can this affect somehow in the context of the call? (Note, if this Is not already clear, I am not a .NET specialist in any way) ...   
 
 < P> Text box will allow you to attach text regardless of maxlength value - it is used only to control user entry. You can create a method that will add new text after verifying that Maximum length is not reached, and if it is, then just start Remove X lines from the beginning.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
