I did reverse engineering through IDA Pro, but I needed to expand my function. Since there was no free space, I renamed the old function (using Hex-view) to avoid a match, created a new section (using PE Explorer) and copied all the assembler code from function between CC there (using Hex-view). Next, I selected Edit->Function->Create function, and entered a new name instead of "sub". Attempts to apply the changes to the DLL file were unsuccessful (I use Edit->Apply patches to program). I also did not find a program that allows you to add values to the EAT table. Please, help.
