Use regular expressions in Visual Studio to quickly find and replace

The find-replace in Visual Studio can use a regular expression:

 

Example:

 

From:

 

 

# Define ds_min_error 0

# Define ds_error 0

# Define ds_download_error 1

# Define ds_db_download_error 2

# Define ds_fd_init_error 3 // cfiledownload init Error

# Define ds_db_init_error 4 // cfiledownload: dbinfo init Error

# Define ds_max_error 99

 

# Define ds_db_complete 100

# Define ds_download_complete 101

 

 

# Define ds_fd_raw 200 // cfiledownload initialization status

# Define ds_fd_waiting 201 // fd_waiting

# Deprecision ds_fd_downloading 202

 

 

# Define ds_write_file 300

# Define ds_db_write_file 301

 

# Define ds_relocation 400

 

 

Changed:

 

 

Ds_min_error = 0;

Ds_error = 0;

Ds_download_error = 1;

Ds_db_download_error = 2;

Ds_fd_init_error = 3; // cfiledownload init Error

Ds_db_init_error = 4; // cfiledownload: dbinfo init Error

Ds_max_error = 99;

 

Ds_db_complet = 100;

Ds_download_complete = 101;

 

 

Ds_fd_raw = 200; // cfiledownload initialization status

Ds_fd_waiting = 201; // fd_waiting waits for the download to start.

Ds_fd_downloading = 202;

 

 

Ds_write_file = 300;

Ds_db_write_file = 301;

 

Ds_relocation = 400;

 

 

In the replace menu, enter:
