  1. Re: mysql - Can having too many fields be inefficient?

    It really depends on how you need to use the data (I'm always very data-driven, so how I'll use my data decides how I'll design).

    The advantage of splitting stuff up into columns/fields means you...
  2. Re: query hints maximum command buffer size of 1023 bytes

    Without knowing anything about the query or circumstances - I can only suggest working on fragmenting it into multiple smaller queries.

    Re: Which is more efficient

    If you want to do something with an exception - even ignore it, you'll need a catch regardless of performance. (which basically is only a factor if an exception occurs)

    Re: DTD - parameter entity

    Been a very long time since I've done any DTD, however I'd say your example XML looks wrong to me.
    Is that taken from a real example/requirement or is it just something you put together to try and...
  5. Re: Updating a datatable and also validating a check box

    Divide the task into subtasks and solve them one at the time.

    For example:
    First - make sure you can postback when your checkbox is clicked (there's a property you can set on checkbox'es that'll...

    Re: Ajax UpdatePanel

    Make the content from other pages into a UserControl instead of a full page.
    That should make it easier to place within your update panel.

    UserControls are good when you want to reuse the...

    Re: ASP.NET escape quotes?

    It's different whether you use C# or VB.NET.
    If using C# it is \ if I remember right (can also use @before a string)
    If using VB.NET an additional " will escape the following ".

  9. Re: *Ironic angry face* Dynamically creating methods for dynamically created buttons

    I've never done something similar to that, but my guess is that the reason your button is overwritten is that you use the same button variable


    Dim NPB As Button

    Therefore by assigning a new...
  10. Re: Why can't I format a decimal into a string?

    C# in asp.net works as C#.

    So the problem is with the input.
    My guess is that you enter the number in some sort of culture specific value, say using comma as decimal point instead of period, or...
  11. Re: Why can't I format a decimal into a string?

    I'm unsure of what result you want, but the ToString method should be able to do it.
    Check out:

    and see if it helps.

    Re: Select unique latest record from sql database

    Management Studio does not need to be installed on the server. It just needs to be able to connect to the server on the SQL Server port.
  15. Re: Left join problem while translating from SQL to MSaccess

    My guess without parsing the entire thing through - you have a problem with your parenthesis. You do have a lot of them.
    Properly the OR is interpreted wrong due to them.

    I would advice you to...

    Re: Help. How can I log people out of a database

    Depending on how harsly you want to do it in SQL Server, you can just kill all connections as you detach the database.

    Otherwise - more "soft", depending on how people log in (if they log in via...

    You need a property in your usercontrol (.ascx) to set the value of your label.

    When you get the error you should also get a stack trace which indicates what line the exception was thrown from.

    Re: SQL validated, but causes crash

    Well - from the error message I'd say it isn't the query which is your problem.

    FYI - but you might also want to look at the TryParse of the number values, which means you do not manually have to enclose the "Parse" in a Try/Catch block.

    It works (almost) like parse, except...
