RE: [Dev-C++] Reg Prog. (Frazell Thomas)

[Ramana K. <ra...@my...>]

I haven’t thoroughly read all this code regarding the registry, but, if Hoo
Hong’s code works, there may be a difference (or problem) with you system
setup, Frazell. What OS are you using, and what does your registry look like
(in regedit) – compare this with Hoo Hong’s. If the program doesn’t even
compile, yet compiles on another system, maybe you should check all the
settings and/or re-install Dev-C++. I saw that your hard drive is E:, I’m
not sure, but maybe Dev-C++ automatically sets up its default settings to a
hard drive which is C:. Go to Options->Compiler Options and check that
everything is all right.

Does anyone know if there exists a compilation of all the API functions and
their argument and what they do?
If it exists, I’m sure it would be a godsend for the people (like Hoo,
Frazell and I) who are working with the Win32 API.

I hope we find a solution soon,

[Hoo H. <hoo...@ho...>]

hi,

  I've just tried compiling the piece of code, it works perfectly with Dev
C++ as well as MS Visual C++. Don't simply copy the source from your email
client and paste it into a .cpp file ... you need to modify a bit because
email client may inserts some characters (line feed , carriage return) here
and there. Anyway, try to compile the .cpp file attached. If the error
persists, I guess there must be a problem with your system or your Dev-C++.

RE: [Dev-C++] Reg Prog. (Frazell Thomas)

[Larry H. <lm_...@ya...>]

I was able to compile Hoo Hong's code from the attachment sent, not=20
straight from a copy of the original post. The code does work on my Win98=20
system.

I find it very interesting code, and can see some uses in my job,=20
especially for fixing known problems with the registry, or doing custom=20
edits. Granted a .reg file can do the job, but this helps one learn=20
programming skills! <g> I can see how this could be easily modified for=20
custom input during program execution, in a word, cool!

I am in the playing stage of working with C/C++, since I do not have time=20
