    a simple string question

    For docs, I find the WinHelp or HTMLHelp version better than looking at them in a browser. Only available for windows. http://java.sun.com/docs/windows_format.html Mark [openup]

    any java IDE that is similar to Visual Studio

    BTW JDeveloper from Oracle is free now. It is pretty good on Visual component design. But it won't be the same as visual studio since Swing is not the same as Windows Forms. Mark [openup]

    Compression of contents of a Long field

    Thank you. I will try it. I did not think of that. Mark [openup]

    Compression of contents of a Long field

    Hi We have a table which has a long field containing essentially clob (text) information. The text compresses well by zip. We'd like to compress the text, and have Oracle do this transparently on insert and select for us, ideally. Is this at all possible? The field may or may not have to...

    LinkButtons inside Datagrid

    When you say you have <TD> on line 95, how exactly do you determine this? The best way to locate the error is to say yes when IE asks you if you would like to debug, then choose to debug script (the default). VS.net should then highlight the exact location of the problem. Start from IE in a...

    Writing connection strings for Oracle

    Hi I guess if you want to ask the same question in two forums, you could reference the other post in both. Also, if someone satisfactorily answers your question in another forum, you should post back and tell people that you have an answer. There are no hard and fast rules - it is just that if...

    Writing connection strings for Oracle

    I have just noticed that you cross-posted this same question in the VB6 forum. That is bad... Mark [openup]

    Writing connection strings for Oracle

    http://www.connectionstrings.com/ There is an example under Oracle, ole db connection, for operating system authentication, which I think is the same as what you are doing with SQL Server here. I have never used OS auth with Oracle from VB or .net, though... Mark [openup]

    Create RunTime Assembly

    System.Reflection.Emit This is not something with which I am familiar, but this might be what you are looking for http://weblogs.asp.net/joelpob/archive/2004/01/21/61411.aspx I've not found anything which allows you to compile source code at run time, but I've never had a need for it. HTH...

    Encrypting a config file

    In this scenario (and also in 3 tier apps), the account by which the application is accessing SQL should be a least privileged account. That way, if the user gets the password, they can only connect and do the same things the app can do. If you encrpt the config entry, someone can still...

    Simple Checksum

    That comes out at about 5%, which is worse. I think the reason is still the mod 10 step at the end. The clever bit is mod 11 - I think it is undoing some of the cleverness to do a mod 10 as well. I am not an expert on checksums obviously :), so I am not sure. Thanks Mark [openup]

    Simple Checksum

    I just had a thought. I was wondering why you mod 10 the result of the mod 11 operation. And then I figured that you did this because your check digit had to be a single numeric character. Mine doesn't. If I just leave it as mod 11, and use 'A' or something when the result of the mod 11...

    Simple Checksum

    Oh forgot to mention that to test the code I changed the function so that it just returns the checksum digit, rather than the concatenation of the input and checksum. Mark [openup]

    Simple Checksum

    Thank you. Testing this shows that out of about 4,500 errors where any 2 digits are swapped in codes of 4 or five digits, it fails to detect about 2% of the time. Out of about the same number where 2 consecutive digits are swapped (the most common kind of error), it fails also about 2% of the...

    Simple Checksum

    Hi I was wondering if anyone could point me to the explanation for a simple checksum algorithm I could write in PL/SQL. It doesn't have to be very fast, and it only has to detect typographical errors in 5,6 or 7 digit numbers. I looked at CRC, but I could not figure out what that was doing...
