Context please? Where is this code?

A string has to be placed between delimiters (and those delimiters varies according to the language or tool. With some tools it would be:
strclinic ="o'chp"

Open in new window

in vb.net? Which error? can you show more code because if your value containing a ' is in a variable, it should work.

1- can you confirm it is vb.net?

2- You cannot assign a value to .ToString as Tostring is a method and cannot receive a value

3- as already said, a string value needs to be enclosed between delimiters:
 StrClinic = "o'abc"

Open in new window

you are not showing complete code! How am I supposed to guess what you are doing and what is your code? I have provided code that I know is working (StrClinic = "o'abc") and I don't event if you are using it and where you are using it.

I am more than please to help you but you really need to help me back!

And BTW, a delimiter is a character used to surround a string value which in this case is the "

In this specific scenario, you don't need to double the quote. it should only be:
CmbClinic.Text = StrClinic

Do you have an event on CmbClinic? The error is not coming from this line but it might be triggered by this line. Your debugger is supposed to stop exactly on the line causing the error. What is that line?
