Does this mean the nasty, autogenerated SQL ? I recommend writing your own, in stored procs.

What is "SQL Dependency"?

I dont knwo what this 'SQL DEPENDENCY' really is? but I think your problem can be solved if u just write a simple SQL Query and well Query your Database and offcourse show the result or whatever!!
hope that helps

Why is everyone using the MS Flexgrid still ?
You need to download the Office toolkit from Microsoft, it will allow you to control Office from .NET. Of course, the code only works on PCs that have Office installed.

I add some objects of a user defined class,using Listbox.Items.Add().
And somehow change the value of one item object,don't the display supposed to be changed with that? I have tried update() and refresh(),but it did't work.
How to make the display change with the item object?
|
|
|
|
|
if you're changing the contents dynamically then you need to re-populate the list box by clearing the contents first and then adding them back again
hope it helps

Thanks for your help!I remove the item before changed,and add it to the listbox again,it works. But I thought it could be implemented by repaint or upate the listbox.

hi,
i need to pass following callback function to c++ from c#
(*func1)(double *p, double *hx, int m, int n, void *adata)
how do i define this function in c# and how do i pass it to c++?
Hope anyone can help me.

Hi,
you need to define a delegate, like so:
public delegate void func1(ref double p, ref double hx, int m, int n, IntPtr adata);
then pass an instance such as new DifoEventHandler(myFunc1) to the other party,
where myFunc1 is the method that has the appropriate signature.
If the void* is to be used in a managed environment you would have to
either adapt the definitions statically, or add code that handles it at run-time.

I want to check server connection at every transaction. how?

just use the server exception I'm forgetting its name at the moment.. but when u catch that one in the catch block. you'd know that the connection has been severed n then you can take appropriate action.
oh yes the name is SqlException (incase your using SQL Server).
use its message or tostring representation intelligently now!

if i have a text file with a whole lot of names in it, how do i bind that to check boxes on a simple form.
i would use a stream reader to get the data from the text file, could i then use a for each loop to run through the data within the text file and bind each check box to each line in the text file?
Thanks
Dan

I don't know what you mean by 'bind'. You're going to set your checkbox values based on what you find in the text file, but you won't 'bind' in the sense that you cannot make it so the file gets changed when you change the check value of a control.

ok ye i hear you... but how do i make the check boxes display each line individually from the text file. so do i use a stream reader and for each line that is read, set the check box text to that which is in the text file?
|

The easiest way IMO is to use File.ReadAllLines to get a string array from the file. Then you can just iterate over that, and do whatever you like with it ( for example, setting the text of a control ). If your controls appear in order on your form, you could even iterate over the Controls collection of the form, and increment an index for your lookup string every time you find a check box.

I thought I'd get lucky with Google on this one, but unfortuantely didn't find anything. Or may be i was searching using the wrong keywords. (I'd put my bet on the latter)
Preamble:
I created a hello-world NT service in C# (nothing fancy here -- no WCF involved) and using installutil I'm able to deploy the service and then eventually using net start, I'm able to run the service as well. The service is running under "local system" account. The service has a timer, which ticks, say every 1 minute.
Question:
During the timer tick event handler, I'd like to find out a) if there is ANY user logged in at this time and b) if so, what is the name of the user who is using the machine?
I'm not interested to know which account is being used to run the NT service.
I tried System.Enviornment.UserName but that doesn't return what I need. It simply returns "user name of the person who started the current thread.".

I hope to find a trivial solution to a trivial problem.
Thanks,

System.Diagnostics.Process should do what you need with regards to launching exe and passing in parameters. Unless you mean passing input to your own exe. In which case, use the args[] array parameter of the Main method.
A quick question for you : In which language do you specialise as a software engineer?

Hi
I have a dataset contains 37 columns and 4500 rows. For one of my business requirement, I'm reading the values into an string array and go for further processing.
Now, when it comes to next row, I want to make the array as new one as if no value should be there. It should be null? So any idea how to delete the array values? Is it correct if I make the string array = null?
Please advice. Many thanks

Hi, if you only want to make the array as new one, I think you can do that, either set the array to null or use "array = string.Empty", and the latter is better.
Thanks
