there is my code:

nResult = RegDBSetDefaultRoot ( HKEY_LOCAL_MACHINE );

szSubKey = "software\\pai\\ced\\GEN_LG_NOM_APP_LIGNE";
if ( RegDBKeyExist ( szSubKey ) = 1 ) then
nResult = RegDBDeleteKey ( "software\\pai\\ced\\GEN_LG_NOM_APP_LIGNE" );
endif;

well, I can't get the darn key to be deleted.....funny RegDBKeyExist(szSubKey ) = 1 ) is not true!!! hence the "fail"...
but the Key exist under
HKEY_LOCAL_MACHINE\\software\\pai\\ced\\GEN_LG_NOM_APP_LIGNE

any idea why I con't find it via this fonction????

TIA
Mike

Hi Mike,

Hmm, I can't explain why your function isn't returning a 1 when using this function. One idea that comes to mind, is that some other process is removing the key before your code is executed.

I know when I'm doing registry key removals, it is during an uninstall operation. I'm not overly concerned about looking for a key that I want to delete. So, perhaps consider taking a different approach?

Instead of checking for a registry key that you know exists, have some error handling in case the delete fails. For example

CODE

nResult = RegDBDeleteKey ( "software\\pai\\ced\\GEN_LG_NOM_APP_LIGNE" );

if(nResult = failure) then
MessageBox("Delete Key failed", MB_OK);
//other error handling here
endif;

The advantage is the delete key function is being executed, but you still have something in place to deal with failure. I hope this work around helps.

Thanks Mike,

but still the same.....
I've tried this before.....I really don't know why...it seems like I don't put the correct key (path) name...
really I am confused......

Hi again Mike,

Sorry the last idea didn't help. Here's another...

In your example you have

CODE

nResult = RegDBDeleteKey ( "software\\pai\\ced\\GEN_LG_NOM_APP_LIGNE" );

why not replace this with

CODE

nResult = RegDBDeleteKey (szSubKey);

//szSubKey was the same variable used in your earlier example

Is there a reason you aren't using that variable twice?

Did you set this key in the DevStudio Registry IDE? Without knowing anything, I am thinking that the auto-remove feature is taking out your key before it gets to your code. Maybe you can double check this? It might be ridiculous, but it couldn't hurt to look.
