To find a piece of word anywhere in combobox

@James Axsom I do place the break point line by line. There is no error.

What can I do else? 

Thanks.

Next step. This is your code snippet which you say is crashing.

 

 

 

On my line 1 above (while may be different in your code window) please place a break point there, run your code and step the execution. There will be a point in time where the application breaks. You have to watch it. Step it slowly, line by line.

 

When you step it the line will turn yellow showing that the execution is on that line. Step it again it will move to the next the line. As soon as a line of code throws an exception, execution will stop and an error will show up. When that happens remember where that took place and let me know where it happened.

 

Thanks. 

The error message I receive is strange:

Additional information: Reading attempt or recording in protected memory. Usually, that is an indication that other memory is damaged. 

You run this code and it crashes.

What exception message does visual studio tell you?

At point in the code does the exception take place?

 

Would you being willing to place a breakpoint in your code and step through it and see where the exception is taking place? 

Big sorry, you didnt get well my question. Read me well and will understand.
