hi.
I wonder if there is any way to backup my registry using straight C++ 6 code or vb6 code. (I am using win 2000).
Ths.

Check out the Win32 registry API (RegEnumKeys, etc.) It's ugly, but will get you going. Note that if you are on Windows NT, 2000, or XP, you will have to be administrator to be able to read some of the keys.

Sometimes I feel like I'm a USB printer in a parallel universe.

Backing Up My registry using these Api functions is Eek! | :eek:

. I need something really simple.

To back up the whole registry, use the Windows NT Backup tool (Ntbackup.exe) and use the option to back up the registry. Or, run the rdisk /s command.

check msdn for details...

It's not a bug, it's an undocumented feature.

See RegSaveKey() in MSDN. Smile | :)

Ths. This is very useful.

Actually after i red about it, it is much less useful.
SaveKey/Restore Key save the Key Contents, but not the key itself neither its security and other attributes. Cry | :((

CMD script woes

When I execute these commands at the DOS prompt, they work just fine - i.e., a file called version.h is created. The file contains the line #define Major 4.

C:\> set arg=4.5.2-RC8
C:\> for /f "delims=.- tokens=1" %i in ("%arg%") do @set major=%i
C:\> echo #define Major %major% > version.h

But if I put these lines in a CMD script (eg: createVer.cmd) and execute it from the command line, I get the following error:

C:\> createVer
C:\> set arg=4.5.2-RC8
argi was unexpected at this time.
C:\> for /f "delims=.- tokens=1" argi
C:\>

Any idea what I'm doing wrong? Confused | :confused:

The command processor does some bizarre read-ahead stuff which can lead to earlier definitions going crazy.

See help set for information on delayed environment variable substitution - basically, you surround the variable name with ! rather than %.

I'll admit that when I was trying to do something similar, I wrote a C++ program. It's a lot more controllable.

Thanks, Mike! I was able to fix it by using the %% notation (reqd in scripts).

It's a known issue with the command interp. Need to use %%i instead of %i when including commands in a script.

Help with fscanf

Hi People ! Cool | :cool:

I ´m programming an 32 bit application that has to read a series of nunbers from a formated TXT file.

I was thinking about using fscanf but I realized that I need to open the file with fopen , that is an absolete function ... Cry | :((

Well.. I´d like to know if is there another alternative for fscanf , or if I can use fscanf even opening the file with CreateFile. Is there a new function to read a formated file , that is compatible with Createfile ? Confused | :confused:

Thank you in advande

what does "absolete" mean? if you mean "obsolete", then, no, it's not. it still works fine.

Humm . I have heard about some people that had problems using it in 32 bit applications ...

Which means they were not using it correctly. Being obsolete means that it is not available to use, correct or otherwise.

What's obsolete about it? Are you using Visual Studio v7.x?

i don't think fscanf is obsolete...

anyway, if you prefer the "younger" std::cin, you can thus read series of numbers too.
You will have to open a stream associated to your target file, and then do as much as cin as you want...

watch for iostreams in the msdn for details.

If you like, you can use a method other than fopen to open the file, read a line of text, and use sscanf to parse it.

wasn't sscanf designed to read from strings ? (C-syle strings i heard)...

Sure, but it works just fine. The only problem with sscanf is that it is MUCH easier to shoot yourself in the foot or introduce buffer overruns.

I'm going to patent thought. I have yet to see any prior art.
