Hi There, You do that by using the unsafe keyword, pointers are not safe type in c#, and as you know c# uses managed code which uses garbage collector, but in un-managed code the garbage collector cant interfear, pointers in c# requires writing unmanaged code, therefore you have to use the unsafe keyword.

Are you certain about the connection string and there is data in the source datatable ?!

Hi there, What kind of error you are getting ?! if no exception then did you make sure that the source datatable has data? and is the connection string correct to be for the destination database ?!

Do the following: - Use the property of the button OnClientClick="SumValues()" to do the summation on client side - Add a javascript function SumValues() for example and make it sum the text values, to get the value of each textbox use getElementById in javascript.

You know ... sometimes I think that the compiler should'nt compile such a code !! and display a message for the developer :"For God Sake What with the hell is that !!!" :)

The other day I saw a code where the developer intended to check his code by displaying a message box in ASP.NET applicatoin if a condition is true, in order to accomplish this he refrenced the System.Windows.Forms assembly and called the MessageBox to display his message. When running the code, it actually worked !! and displayed the message successfully !!! I freezed when I saw this ! How come a windows form control message box is displayed on the browser ?! Actually it makes all the sense to be displayed from a technical point of view ... but it will create a disaster when its really used !!! what actually happens is that when the MessageBox is displayed the thread of the process is freezed until the User clicks ok !!!! and what user is that ... figured out the trick ?!!? Let me give an example : the application on server ABC and some user on machine xyz is browsing the application, now when he faces the condition and the message should be displayed it will not be displayed to XYZ User !!! it will be displayed on ABC server since its a server side call !!!! Now he had no clue about that because he was in development time on his machine, and his machine in debugging is the server as well, so he was able to see the message box with no problem :) It's a codding horror no doubt ... but it makes an asp.net developer thinks more realistic and deeper on the behaviour of his own applications !!!

Hi there, What you are doing is a server validation using the Validators set on the page, and Page.IsValid property returns a value according to wether a certain Validation Group is valid or not OR all validation controls are valid or not on the page. In other words checking its value immediatley will be with no value for you, you have to call Page.Validate(validationGroupName) first in order for this value to return the desired and good value of it. You can call Page.Validate() to validate all validators on the page, or call Page.Validate(validationGroupName) if you have a group, you can set a group of validation on the controls using the ValidationGroup property if you wanted. Hope that helps.

This is a pre-compiled version you have where it eliminates the cs or vb files and convert it to dlls in the bin folder in order to work on production environement.

Simply as you said it holds white spaces in the tag ! You can't have white spaces in the tag UNLESS you will be adding an attribute ... the tag name should always be one word whitespace-less !

Hi there, I think you already knew half the solution to your problem ... the returned null object from FindControl is because he really cant find it in Cell[6]... well try going more deeper ... use the debugger to see all controls inside Cell[6] and then in each one try finding your dropdownlist ... I think all you have to do is go one step deeper as I recall for the EditTemplate.

Hi there, First of all table control cant be nested in (a) tag (this will not make the content clickable), second of all you should be using tr and td tags within a table ... To solve this you could use the following example: <table> <tr> <td> <a href="Home.aspx">Hit Me</a> </td> </tr> </table> Here you are nesting the (a) element inside the table element in which it will be clickable according to the behaviour you want. Hope that helped !

It depends on what you want, taking in consideration that there is a main form that shouldn't be closed, other forms could be, and you have the option of closing the forms or hiding them, preferrably is to close them of course except the main form which should be just hidden.

Hi, I am not sure what is the question is ... constructors can be declared to create a new object of that class ... they can by public (accessible to outer classes) or private (only to the same class) now its not commonly used to declare a private constructor ... most common case is when you are creating a singleton object (read about singleton design pattern)... but can we use constructors in the same class ? Yes we can ... no roles can forbid doing so ...
