Navsyst2 · 2006-08-08

Hi..

can anyone help me with code example?

I am using automation 'Windows Script Host Object Model'.WshShell'

Which properties should I use to check it?

WshShell - Methods - (Run, Popup, CreateShortcut, ExpandEnvironmentStrings, RegRead, RegWrite, RegDelete, LogEvent, AppActivate, SendKeys, Exec)

Thanks.

It would help if you can explain what you're trying to do.

Please use the search. I've posted an example of this here or at mbsonline.org

Hi ajhvdb,
I've searched the forum before, but didn't found it. Just searched through all ypur posting, nothing

what I want to do?

I want to delete a registry key before starting one batchprogramm. But to delete it, i must check it if the registry exists, otherwise got an error.

I hope that it's enough.

Thanks.

WSH groups have already solved this problem. You need to translate the code, which isn't that difficult. See:

You're lucky

. I've downloaded the whole site before troubles began.

//Name-DataType-Subtype-Length
//LatmWshShell-Automation-'Windows Script Host Object Model'.WshShell-
//LvVAR1-Variant--
//LvVAR2-Variant--
//LvVAR3-Variant--
//LvValue-Variant--

CREATE(LatmWshShell);
LvVAR1 := 'HKCU\Environment\TEST';
LvVAR2 := 'blablabla';
LvVAR3 := 'REG_SZ';

//Write
LatmWshShell.RegWrite(LvVAR1, LvVAR2, LvVAR3);

//Read
LvValue := LatmWshShell.RegRead(LvVAR1);

MESSAGE(FORMAT(LvValue));

CLEAR(LatmWshShell);

Did you try searching THIS forum? Hint: use "read and registry" as your search key words.

Thanks luc for your help.
It would be better for me if you tell me the topics title too

Ok.. I solve it with indirect way.
First create the registry and then check it if Format('HKCU....') <> '' THEN
regDelete.

ajhvdb, thanks too for your help

Another idea is still welcome

Shall I come over to your place and type it in for you?

It's better for your brain if you do some little exploration yourself.
