The first one.
Seriously, your question is too broad and general to get a meaningful answer. You're more likely to get a meaningful answer if you post specific questions, e.g. "For a client/server architecture where both are .NET apps, should I use .NET remoting or WCF?"

Both of my applications are in C#. At Present I am using Asynchronous
Socket Programming. Reliability is my main concern. I cannot achieve this in
Asynchronous Socket Programming.I have to send data frequently that too from
more than one client.

wanting something to work doens't make it so 
you have to actually execute the command, and then read it with a reader, or alternatively fill a dataset with the results and read them from there.
Look up some ADO.NET tutorials.
What you are doing right now, and where it fails, is easily explained:
krajah1984 wrote: string commandString = "SELECT password from table1";
SqlDataAdapter dataAdapter = new SqlDataAdapter(commandString, conn);
string strEnteredPassword = textBox1.Text;
if (strEnteredPassword == commandString)
you are checking if "ABCD" is equal to "SELECT password from table1".
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Tq for reply.
Where is my mistake and what to add,im beginer for database connection.

I told you what your mistake was. You can't just compare a command to the desired result. You have to execute the command, get the results, and then compare these.
Pleae follow this tutorial, it will help you a lot probably:

Hi,
I m trying to extract all the images tags from the HTML page,
i tried the below regex pattern,
<img\s.*src=.*>{1}
this works fine when the HTML pagesource has tags in the single line..
This patterns fails when the image tag is splitted to two or more lines..
eg.. <img
height=73
alt="rtg, software="" testing="" services"
src="sample_files/rtglogo.gif" width="186" border="0">
plz help me.
regards,
nas

Just put the entire HTML file into a string, remove the carriage returns then run your reg expr.

hi,
thanx for reply..
i tried that too but unfortunately, i get only one match that too a huge line of all the code..
regards,

Did you remove \n and \r?
|
|
|
|
|
|
Try <img[^src]*src=[^>]*>{1}
|
|
|
|
|
that won't work because you can't have 's', 'r' or 'c' before the 'src' portion of your img.
Sadly I don't have the answer (I'm trying to understand regex too)

public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Very true, in that case - <img[^>]*src=[^>]*>
That's even if he needs the src= bit in there, would probably work as <img[^>]*>

Hello all,
I am using a Windows Mobile 5.0 PPC device. I have a c# application that uses GPRS to communicate with back-end systems. Now, I want to prevent any user of the device from using the phone (e.g. dial numbers, make calls etc) and at the same time, allow my application to connect to GPRS.
In a way, I just want to disable (turn off) the phone program. I have tried to turn off phone manually but this prevents my application from connecting to GPRS with a message "Cannot connect. Ensure that your phone is turned on and correctly configured and that service is available, before trying again".
Any help please. Thanks!

I'm playing around with resources files, adding images to them etc, but I saw that you can also add string values to it, how advisable would it be to add a connection string in that, for example database connection string?
Thanks in advance

Hello,
Can you give additional information what you want to achieve?
I have used resource files (for the string values) mainly dealing with the localization issues, whereby my application interface has to be in difference languages etc, and resource files provide great help. Otherwise, using resource files to keep your images etc..embeds the resources in your assembly, thus you won't need any other extra files such as .jpg etc..
The connection string can be a constant in your code as well. Does this help?

I learning myself C# and came across this, so there's nothing I want or need to do, just wondered how it worked and what it is for. The fact that you can load icons and images appealed to me because I didn't need to include them to the solution, just added them to the resource file and reference them from there.
That's when I came across the strings you could save and wondered what type of string you would save in there

Normally, you would use this to store localized versions of text. Instead of using the text "Hello" in your program, you would have a localized resource which contained the text and you would just use the resource instead. This means that you can create internationalized applications just by swapping resources.

If I could I would have voted you 5 twice, that make sense, thanks.

Hello my name is Mike.
I was interested in your response and if you don't mind would like to ask an additional question?
Pete O`Hanlon wrote: This means that you can create internationalized applications just by swapping resources.
Does this mean that to be able to use the resources you can swap them on the fly as opposed to re-building solution?
Thanks,
Mike

In a sense, yes. You create localized resource files and by dropping them into certain specially named folders, your application will be localized base on the relevant resource. For instance, if your culture is FR-Fr, then by dropping the localized version into the Fr-fr directory, you will see a localized French version.

Thanks for the info was just curious. I thought maybe there was a way to dynamically load them. As an example (off the top of my head) if you had an app to teach a certain subject and you wanted to aim it towards different levels of audience you might have a beginners, inter. and pro and have resources for each.
Thanks
Mike
