// Suppose you have "foo.chm" which consists of
// multiple html pages, and you want to display
// "bar.htm" at this time:
::ShellExecute(NULL, 
              "open", // verb
              "hh.exe", // this file located at Windows directory on every machine which has IE5.0 or higher installed
              "foo.chm::/bar.htm", // yeah this is the trick, you can even do "foo.chm::/bar.htm#blah"
              NULL, // current directory
              SW_SHOW);

Enjoy!

Running a function as the dialog starts

Hey,

Probably a stupid question but how do I get a function to run after the dialog has loaded?

The situation is I'm writing a mp3->wav converter where a dialog should load up with a progress bar and a couple of static text labels. I just want it to load the dialog then run the Decompress function without any user input at all.

Putting the function call in initInstance just runs it before the dialog has loaded, and putting it in the constructor for the Dialog is causing an error in wincore.cpp.

Any ideas how to fix this silly problem? thanks guys Smile | :)

I'm not too sure what you're meaning I'm afraid. I got it wrong in my first post, I was called the dialogs initDialog() and not the initinstance function.

do you mean changing the int nResponse = dlg.DoModal(); line in the app class? I tried changing that to dlg.ShowWindow(SW_SHOWNORMAL) but its giving errors Frown | :(

Sorry to be a pain in the ass about this and thanks for your help

You've got plenty of modeless dialog code snippets on CodeProject to play with.

Pick a command ID, such as 100, then at the end of OnInitDialog(), call

PostMessage ( WM_COMMAND, 100 );

Add a handler for that command ID to the dialog, and do the conversion in that handler.

Registry - How to write in HKEY_LOCAL_MACHINE section?

julych9-Nov-02 9:31

Please tell me how or what to change in order to be able to write in HKEY_LOCAL_MACHINE-section of the registry.
Now I'm using the SetRegistryKey(), m_pszRegistryKey and WriteProfileString()
but I can't make them write anywhere else but in HKEY_CURRENT_USER.
Any help will be greatly appreciated!

Re: Registry - How to write in HKEY_LOCAL_MACHINE section?

Stephane Rodriguez.9-Nov-02 10:00

May be a security issue. Check out you are allowed any write access with the regedt32 tool, (security menu).

I doubt it's a security issue, because it's about writing a key in HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Run - it's about a key that starts my application when Windows starts. Any suggestions how can I do this in other way?

Re: Registry - How to write in HKEY_LOCAL_MACHINE section?

WriteProfileString() is only used for per-user data such as options for the program. To write to any key in the registry, use the registry APIs or CRegKey in ATL.

Hello there,

I've some Binary and Text data in some files.
What's the best algorithm to encrypt them ?

Blowfish works for me. There are Dept. of Commerce restrictions that may apply to you if you develop software in the US for export.

I found these encryption algorithms for both text and binary files, all written in C. Hope it helps:

Best by what measure?
Are you looking for serious security?
(Get the password from outside source,
pass through one-way hash, and use as
the key for a symmetric cipher like
Blowfish?) or...

If the key is a part of your program
(i.e. encoded somewhere reachable),
and you just want a bit of obfuscation,
why not get a little benefit and just
compress the data using some fast alg
like LZSS?

my compiler doesn't recognize????

Can anyone tell me what includes are needed for TrackMouseEvent or even the GET_X_LPARAM macros to be recognized...I have included winuser/windows.h I have linked with user32.lib...I am stumped. I am missing some kind of update here? Using MS VC++ 6.0 under Windows XP.

Re: my compiler doesn't recognize????

Stephane Rodriguez.9-Nov-02 8:45

_TrackMouseEvent is in commctrl.h
GET_X_LPARAM is in windowsx.h

The latest platform SDK is not even needed. That's the search results for an old VC6 install.

Resource Id

How can I retrieve the resource of a entry in the string table. That is knowing the name, "IDS_STRING1" to retrieve the int value and thus to be able to retrieve the caption of the specific entry.

Using that I have to provide the IDS_STRING1 which actually is the int value. What I am saying is to have the name on a string that is CString hhh = "IDS_STRING1" and with that to be able to find the caption of that the entry that has the same name in the string table

Spiros Prantalos

Re: Resource Id

Michael Dunn9-Nov-02 12:07

Michael Dunn

9-Nov-02 12:07

You can't do that directly. The compiler never sees "IDS_STRING1", only the number that it is #defined as.
You'll need to create a lookup table (using std::map for example) to convert from the string to the numerical equivalent.
