message box... check date/time

Hi all,
as you can't display a message box using vb.net, i have had to use javascript...

i am using a Popup Calendar that sent the value of text boxes to the dates selected
i need to make sure that the end date is after the start date.

this is what i am doing at the moment...

function CheckTime(){
if (document.CRC.txtStartDate.value >= document.CRC.txtEndDate.value){
var ErrMsg = "End Date Must be later than Start Date";
alert(ErrMsg);
return false;
}
}

the problem is; example
StartDate = 23/12/2003
EndDate = 13/11/2003

the code thinks that beacuse the first number is greater, then the whole number is, so it doesn't work.

please help.
Thanks
Tom

I'm not sure i'm with you here because you can display a message box in vb .net:

VB Code:

MessageBox.Show("Here is a message!")

I'm not sure about the dates though.

MessageBox.Show("Here is a message!")

this is not declared! ??

p.s. i am using web application so system.windows.forms doesn't work, is there a function within web applications?

well for my game i would use

VB Code:

Private sub button1_click (....)
msgbox("Hey, insert your message here")

Thats how you show a msg box but with the calender thing i have to get on my other comp to check

ok, that might work, but i am getting this error:

It is invalid to show a modal dialog or form when the application is not running in UserInteractive mode. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

my project is a web application, if that makes any different

ASP.NET can't show messageboxes you'll need to use some java code in there to do that. Also ASP.NET runs server side so if it could show a messagebox it'd end up on the server not the client.

thanks :)
just found that out ;)

Yep, no message boxes on ASP pages unfortunately. I usually put a well-placed label control on the page with the bgcolor the same as the page itself. That way if I need to use it, it's there, if not, it's invisible.

For whatever it's worth...
