why I lose data after chnage the code or add code
-
Hi guys I have very big question I have a project on Visual Studio, this project include table SQL data. I notice when I add records or add rows with information . imagine that I add more than 1000 rows full with a lot of names and number. the crazy thing that all these data will be removed once I change a little code or add. I wonder how can I protect my data even I make change code time to time.

What makes you think that changing the code in your project magically causes the data in the database to disappear?
Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert. Sometimes it takes a lot of work to be lazy Please stand in front of my pistol, smile and wait for the flash - JSOP 2012

Probably those crazy things he mentioned.

well that what happen to me every time I create SQL table and after save some record like add rows full with information it will be saved and fine but once I change any code or for example create new button on the form the data on the GridviewData will disappear I am not sure if that because I have to change something on the Proprieties

I would have to say no.... the things that you are describing is not possible. If your data was saved then it was saved. You are possibly creating a transaction and not committing. More likely you are clearing the table somewhere in your code. Adding a button to your project will not magically make data in a database just disappear.

Yeah probably. I would not be able to guess which one, out of the 4 or 5 billion crazy things that it could be, is causing the problem

Trying to guess what is going on from what you told us is quite tough... What could happen is that you have your database as a .sdf or .mdb file ; when you change your code, and recompile, the datafile is copied to the output directory. So when you recompile, you overwrite the datafile in the output directory of your projet (the datafile that your application is actually using). But it's just a guess. Unfortunately I lost my crystal ball :)

Please don't expect people to go to other sites to try and understand your question. Explain clearly what your problem is, showing code extracts where necessary, and show what results you expect and what you get.

sometimes words leads you to understand different thing or doesn't make sense for you . reading my words not enough to understand my problem because my English not good enough to express what I need to say it. I speak different language, I don't even understand what database means on my language I just understand what database do. we spent a lot of times chat to each other write to each other youtube that I did will save our time please watch you will not lose anything you are here because you need to help me, http://www.youtube.com/watch?v=jDj_ZD10y0k[^]

I fully appreciate that English is not your native language. Nothing is stopping you from using Google translate to translate your native language into English and then posting that here.

Did you research philo's answer? Did flagging the database not to compile fix the problem? Maybe try that first. If you run the app, stop and then rerun, outside of your IDE and the data is still lost, then you are not saving the data. You need to save the data.
