Cannot currently modify this text in the editor. It is readonly

In VS2008, in a VB.NET windows (WInform) app, I suddenly s开发者_StackOverflow中文版eem to not be able to edit the code and continue in this project.

In Tools-->Option, Edit and continue is checked.

What else can I look for? The files I am trying to modify are not Read only.

Another application probably has a write lock on the file. Restart your PC, or use Process Explorer to find out which process has a handle on the file.

go to Tools >> Import-Export settings and select reset all settings. Hope, This will fix the issue.

Follow below procedure Go to PROJECT -- > PRPORTIES -- > COMPILE -- > ADVANCE COMPILE OPTIONS --- > select TARGET CPU X86

This should solve the problem.
