Alexander,
Buddy, sometimes it doesnot work.
What this logic is simply doing is after taking 7 seven days into consideration it simply deducts 2 days, and after doing this, it sometimes skips the working days as well.
Please help me out.
Best Regards,
The Phantom.

Hey,
I tested the function today and realized I made a mistake in the calculate of weeks.
My line read var weeks = (numDays / 5);. When I wrote this I was thinking in C++ mode, thinking that the division operator would only return a whole number. In Javascript it returns the exact quotient, so we simply need to add the Math.floor function so it looks like this: var weeks = Math.floor(numDays / 5).
Give that a try and see if it works for you. Also, I ran across another problem in your section of the function. You have this line: var month = returnDate.getMonth() + numMonths + 1;. I think that the + 1 is unnecessary and returns the wrong date.
Make those two changes and it should be working for you! I didn't do extensive testing, so if you find any other strange scenarios which don't work, please tell me and I would be happy to correct the code.
Sincerely,
Alexander Wiseman

Alex,
I've done those two changes accordingly, still some places it includes Thursday's and Friday's.
Please have a look.

Okay, I figured it out and this time I've tested it. The remaining problem was caused under these conditions:
1) The startDate is a Thursday or a Friday
2) The number of days being added is a multiple of 5
In this case, the algorithm would always return a Thursday or Friday because it would simple add 7*(number of times 5 goes into numDays). To fix this, all I added was another "else" clause which checked this case and fixed it. Below is the final function:
function DateAdd(startDate, numDays, numMonths, numYears)
{
var returnDate = new Date(startDate.getTime()) ;
var yearsToAdd = numYears ;
var month = returnDate.getMonth() + numMonths;
if ( month > 11 )
{
yearsToAdd = Math.floor((month+1)/12) ;
month -= 12*yearsToAdd ;
yearsToAdd += numYears ;
}
returnDate.setMonth(month) ;
returnDate.setFullYear(returnDate.getFullYear() + yearsToAdd) ;
var finalDays = 0;
if(numDays >= 5)
{
var weeks = Math.floor((numDays / 5));
finalDays = (weeks * 7);
numDays -= (weeks * 5);
}
var dayOfWeek = returnDate.getDay();
if(numDays > 0)
{
if(dayOfWeek < 4 && (dayOfWeek + numDays) >= 4)
{
finalDays += (numDays + 2);
}
else
{
if(dayOfWeek == 4 || dayOfWeek == 5)
{
finalDays += (numDays + (5-dayOfWeek));
}
else
finalDays += numDays;
}
}
else
{
if(dayOfWeek == 4 || dayOfWeek == 5)
{
finalDays -= (dayOfWeek - 3);
}
}
returnDate.setTime(returnDate.getTime()+60000*60*24*finalDays);
return returnDate;
}
Hope that works for you. I apologize for the mistakes.
Sincerely,
Alexander Wiseman

Alex,
The way you help for writing this snippet is more than the success factor for the snippet.
I really appreciate for your help and you don't need to make the apologize.
I was trying for the whole day on the logic I was thinking on, I made it work but the logic was not efficient enough and it was slowing down the system and eating the memory resources. But I thought you will come up the solution.
Alright, I've tried the code and this time it works but  it doesn't work where I need to get the back days, I mean instead of addition I tried to do subtraction of days, it never works for the condition but when I try to change the code:
if(numDays > 0) to if(numDays > 0 || numDay < 0) to make subtraction work it again took Thursday and Friday.
In the mean time, if you've some time then there is a reverse situaion where I need to calculate the difference between two dates excluding the same non-working days, I already submitted a Thread with the reference:
Calculating Variance excluding non-working days busisoft 23:03 20 Jul '04
Thanks again for your kind help.
Regards,
The Phantom.

Alex,
Please first check this out.
As you said i made the changes, but it only works when I remove the 1 from calculating the month, remember I was adding 1 in calculating month. Now when I remove the 1 it works but what will happen it goes back to the month , for example if the selected date was 26/07/2004 and if we add 1 then it shows 27/06/2004.
Please check it out what's happening.
Thanks.
Regards,
The Phantom.

Hi,
I pasted the function source from my post above into a webpage and tested the scenario you mentioned, but, oddly enough, I didn't have the same problem. Maybe check to see if your function is identical to the one I posted above and then, if that doesn't work, give me the exact code where you invoke the function.
I will look at DateVariance when I have a chance.
Sincerely,
Alexander Wiseman

Hey,
I have looked through your code and discovered why the month is being decreased by 1. You were exactly right when you said that the getMonth() function returns the zero-based index of the month. Your formatting functions assume a one-based index of the month, which means that the when you call FormatDate after the call to AddDayToDate, the month gets set back by 1 (July becomes June, in your test scenario).
Fortunately, there is an easy way to fix this and I have tested it to make sure it works. You need to modify the AddDayToDate function to add one to the month returned by getMonth. Below you will find the modified version of AddDayToDate. Copy it into your code and it should work fine.
function AddDayToDate(plandate, days)
{
var gCurrentDate = new Date(plandate);
var newDate = DateAdd(gCurrentDate, parseInt(days,10),
parseInt(0,10),
parseInt(0,10));
var year = newDate.getFullYear() ;
var month = newDate.getMonth() + 1 ;
var date = newDate.getDate() ;
return date + "/" + month + "/" + year ;
}
Hope that helps! Let me know if it still doesn't work. Also, I haven't had a chance, but I plan to work on the DateVariance function. I already know how to go about it, so it will just be a matter of sitting down and writing the code when I have a free moment.
Sincerely,
Alexander Wiseman

Dear people,
I have been searching for the correct code to call upon a webservice directly from an aspx page.
Can anyone tell me how to do it?
|
|
|
|
|
wherever you need to call a web service, it is same. add a web reference to the asmx, which will create a proxy class for you. Then just make calls to methods as if the Web service is local to you.

Let us say you created web service with some web method called
foo(). Now you create a web page in a new project from which you want to call this web service.
The first thing you need to do is to add a web reference to the Reference node of your project. This opens up a wizard where you need to reference your .asmx or .wdl url reference. Once you do this, you have the localhost( your local website)with the web service ready.
Add a button to your page. In the click event you need to create the following code. Before you write this code, at the top of the page, you need to add:
imports localhost.service1
in the click event add the following code:
dim mysvc as new service1
document.write(mysvc.foo())
ps;The service1 is having the method foo() when you created the web service. I will try to write a codewalk on this next time to the CodeProject.

AWS Report for OpenListing

Suppose you have a web server which is completely dumb, and a client which is served a webpage from that server.
The client opens a socket and sends commands to the server. This works very well with java, but we need to use a handheld pc such as a Palm Tungsten, which doesn't have a java enabled browser...
The web server just serves pages, it's completely dumb in that respect, no ASP, no PHP, no perl, nothing spiffy and useful like that.
|
|
|
|

yeah...what about it? All do is send simple HTTP request to this server and get databack. It's not that hard, I've done it before with my pocket pc...why you ask about this?
Here's one for quicks:
on your PC open a command window (cmd.exe), then type the following:
<br />
telnet www.codeproject.com 80<br />
after the screen goes blank type the following:
<br />
GET / <br />
hit <Enter> twice...
There you have it, a simple HTTP request.

I want to make a select box in a Javascript function, this is my code:
var val = new Array('0','1','2','3','4','5');
var lis = new Array('java','php','asp','jsp','vbscript','jscript');
function makeOption(obj,selectID)
{
obj.options[0] = new Option(lis[0],val[0],false,false)
for(i=1;i<lis.length;i++)
if (val[i]==selectID){
obj.options[i] = new Option(lis[i],val[i],false,true);
}
else{
obj.options[i] = new Option(lis[i],val[i],false,false);
}
}
var selectID = 3
makeOption(document.form1.ProgramList,selectID);
The trouble is in Netscape the selectlist can't make selected with selectID("asp"), the selectlist its always select the first item "java". But this code run correct in IE.
Is Anybody can help me, please? Thanks for all response!
