hi
i am trying to validate a string that contains a date
using DateTime.parse function
but this function accepts for example the date "31-feb-2007" !!
how can i validate the date to be valid not just the format .

Use this function for date validation.
//Date validator
public static bool validateDateTime(object _datetime)
{
try{
DateTime testdate = DateTime.Parse(_datetime as string);
return true;
}
catch{
return false;
}
}
|
|
|
|
|
if you are using VB.NET there is a function - IsDate() which can be used to validate the date.
you could also use compare or range validators, depending on your choice and use, to check the data type. but i don't think these will validate if the date string contains alphabets as expressed in your example.
but if you are using C#.NET, i think try-catch block (as someone already mentioned) will do the job.
hope this helps
regards

try this
bool validatedate(string datestr)<br />
{<br />
try {<br />
System.Globalization.CultureInfo culture = new System.Globalization.CultureInfo("en-US");<br />
DateTime tmpDate= DateTime.ParseExact(date, "dd-MMM-yyyy", culture);<br />
return true;<br />
}<br />
catch(Exception ex)<br />
{<br />
return false;<br />
}<br />
}

Instead of using exception handling as logic as some people have suggested try something like this:
public bool ValidateDate(string date)
{
DateTime temp;
return DateTime.TryParse(date, out temp);
}

Morning all.
I've been playing around with "customizing" the XMLHttp object using javascript to provide some extra functionality to it. Specifically, I've been trying to add a Timestamp field to the object, for tracking purposes.
Now as we all know, a javascript object is just a dictionary with string keys - which is why "object" members can be accessed through either the . operator or the [] operator. So far so good. Now since it's a dictionary, we're able to aritrarily add fields as and when we like, so the following code...
<br />
var obj = new ActiveXObject ("Microsoft.XMLHttp");<br />
obj.Timestamp = new Date();<br />
...should add this field to the object. I've tested under IE7 (no no - don't panic, not moaning bout Firefox - it's even stranger than that!), and alles ist gut. However, when I try it under IE6, I'm getting an "object doesn't support this property or method" error on the assignement of the new field - and a quick watch is telling me that indeed it's not there. (Which makes sense since the assignment is failing)
Anyone know what this might be - according to The Great God Google, there were no syntactic changes in the JS engine for IE7, just performance ones...

In other words, you want to wrap IE and put your own UI on it. Why ?
fgfdhghgfd wrote: which can restrict a porn sites and if any porn words matches then also restrict that sites
Surely someone else has thought of this before you ? Either way, an add in seems like a better idea than bothering with the IE control.

ROTFL.
I'm afraid no-one is going to write it for you. Try to learn a bit about the task at hand, and ask more specific questions.

You can't possibly do more via FTP than push a PDF to your client, who would then need to open it themselves. Are you sure you don't mean HTTP ?
Perhaps if you posted some code so we had some idea of what it is you are trying....

Hello everyone.
I am currently working on a team project for school using ASP.net and VB.net. The problem we are currently having involves panels as group boxes. On one of our pages we have several items grouped in a panel, however, this panel may be of variable width and height. This works fine in older versions of IE and in firefox, but when trying to display the panel in IE 7 it displays only as its pixel length and does not expand to fit the data as it does in other versions.
Does anyone have an idea on how to fix this or an alternate way to do a similar thing? Thank you.

I have a master page and it has one dropdownlist. I has two items. Is this possible that
in content page I can create the instance of this master page and get value of it's selected item in drop0downlist.
e.g mymaster.master is my master page and it has one dropdownlist
and in content page.
myMaster varr = new myMaster();
How can I grab the value of selected item in content page.
|
|

|

You need to set the @MasterType Directive and the you should be able to access it through the page.master property in your code behind.
Hope that helps.

I need to add to my website application the ability to receive up to
30K of XML data from a Windows client application. I know I can use an
XmlTextReader() to receive the data and put it into the cache. What I
am mostly not sure about is how the website is supposed to know that a
client is wanting to connect and send data. Do I set up a polling thread using a Listener socket to check for a connect request or is there a better way?
I have gone through books and web searches trying to find the best way
to send data from my client to the website, but most scenarios
seem to be the server sending data to the client. Any suggestions
would be greatly appreciated.

Just create a specific web page for the windows app to send the data to.
Then use the Request object to get the stream. Once you have the stream you can put it into an xml doc or whatever. All this code can go in your page load of that page.
I have some code that does this for cXML transactions. I can post it if you think it would be helpful.

For anybody who is having the same problem I was having, I solved my problem by attaching an asmx page to my website and simply using a WebMethod that takes a string as an argument. All I have to do is call this method from my client windows application passing it a string of data points. My WebMethod then writes the data to a file where my webpage reads it before displaying. Very simple, but difficult to find information on how to do this. I didn't know that an asmx page could be attached to a website that is not originally a web service unitil I just plain tried it. I guess that makes it a webservice/website. I am in the early stages of learning ASP.net. I hope I am doing this in a practical way. Only time will tell.
