Good choice is CListBox or CListCtrl or even ComboBox but Editbox no.

Extract the data from a serial port, or update an edit control?

See here. Most of the time, SetWindowText() can be used.

You might want to investigate SetRedraw().

You need to check the docs for xpcom. The error means that it cannot find that method, ie it's in a .lib that you haven't included.

Its a linker error and it seems you need to a lib file.

do you actually want to open the file to write or read something?
or are you looking to open the file in notepad automatically.

to write data into file,use
FILE * fp;
fp=fopen("filename.txt","w");
fprintf("hello");
fclose(fp);
to open the file automatically, use
system("notepad filename.txt");

For second section of your question see CFileFind Class .
and for first section are you sure you have this file on the correct path?
