Hullo Folks,
Am trying to develop a point of sale system for a mobile company.
The point of sale is of distribution of airtime to customers.
The Server is on a Linux box and has MySQL database(Airtime recharge numbers are stored here)
Am to develop a client application using C#, the POS is to work in such away that.
The distributor goes to the mobile company, pays say $3000,
So whenever he sells airtime on his account is reduced.
The client will communicate with the server over a GSM modem.
However whenever the Distributor requests for Air-time from the server,
The amount he gets will be cached; the amount cached is what he will sell until,
It goes to zero, then he will request more from the server…then cache it….
This will go on and on until his account at the server goes to Zero.
Look at it in this way, you have a bank account, you need say $500,get to the ATM, withdraw the $500,u will have the $500,but your account balance has been reduced by $500,
So you use that $500,till its over and when you need more, you go back to the ATM for more.
How the airtime will be distributed is in 2 ways.
· The point of sale printer will print the recharge number on a piece of paper
Say 123-674-627-63,which will be given to the customer.
· The distributor should be able to directly load the airtime onto the customer’s phone
Can I please have help on how I can go about this one?
Especially the communication over the GSM modem to the server, which is Linux box.

Hi:
Hello everyOne.
How can i change the default location(usually the first control in the form when view the page source) of _viewState hidden form field in the aspx page.
For eg when some one view the source of my aspx page, the _viewstate field should not show up at the top of the page (in the page source. it looks junk).
I hope u are uderstanding what i m trying to achieve.Its all for SEO perposes.
Any Ideas?
Thanks
Aamir

You can either turn the view state off for a particular control, or even for the entire page...however that's not adviceable as you won't be able to keep the state of your other controls around across post back.
Now if you turn it off for the page, then when you go do source -> view, you are not going to see the view state field there. I am not sure why would you be concerned with where the view state shows up in your source...I mean if you are concerned with the date that you are storing in there being displayed, well its base 64 encoded so a reader can't just read it. However it's not encrypted or anything and there are base 64 decoders out there that can simply decode it for you.
I hope this helps.

He said why, Sam: for SEO (Search Engine Optimisation) purposes. He believes, rightly or wrongly, I wouoldn't know, that having the viewstate near the top of the page, and thus "pushing" the actual content further down, means that search engines such as Google will rank it lower.
I have heard that the position on the page of content can affect it's ranking, but I would also have hoped that Google et al would be smart enough to ignore viewstate.... be interesting to know for sure, I must admit though...
cheers

Fred, thanks for the explanation I guess I didn't pay attention to the SEO aspect of it. I did some research and found this article www.wwwcoder.com/main/parentid/457/site/6173/68/default.aspx. It seems like the popular opinion on this issue is that if you are concerned with your page's ranking by a search engine, then you may want to remove the view state completely and rely on the good ole session state.
Here's another article using DNN, it tells you how to do that.

Sam:
Thanks for replying.
Actaully i want to keep the state of the page.If i turn it off for a page, i would nt be able to do so.
Its for SEO perposes (Or my boss just does not like it).
I want to keep the _viewstate hidden field but i just dont want it to appear at the top of the htmlForm (in View Source) but some where at the bottom.
It has to something the way page renders it controls.I may need to change the default rendering of the controls. I have a slight idea but just dont know the entry point.
Thanks
Aamir

Thanks Sam:
I also found some articals explaining the viewstate delima.
Most of them suggest to place the viewstate in session or cache instead of page.It not only helps in improving the performance but also in page ranking( since all the junk is out of the page).
Tommorow i m going to implement this idea.
I will keep u posted once i am done.
Thanks

Hello guys.
Here is the code to move _VIEWSTATE hidden field from top of the form to
bottom.drop this code in the basepage and then inherit all the pages from the basepage in ur app.
protected override void Render(System.Web.UI.HtmlTextWriter writer)
{
System.IO.StringWriter stringWriter = new System.IO.StringWriter();
HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
base.Render(htmlWriter);
string html = stringWriter.ToString();
int StartPoint = html.IndexOf("= 0)
{
int EndPoint = html.IndexOf("/>", StartPoint) + 2;
string viewstateInput = html.Substring(StartPoint, EndPoint - StartPoint);
html = html.Remove(StartPoint, EndPoint - StartPoint);
int FormEndStart = html.IndexOf("") - 1;
if (FormEndStart >= 0)
{
html = html.Insert(FormEndStart, viewstateInput
}
}
writer.Write(html);
}
Thanks sam:
Thank you everyone.

Hi all! I'm an expereinced asp.net developer, I want to learn AJAX but after searching on the net I found everything is messy please suggest some resource which should be from the ground up and simple enough. very confused about AJAX,Atlas etc. Downloaded an article from codeproject but could not use it , it gives error please help
Thanks
Don't Quit

Actually I disagree.... yes, this si good but IMHO before moving on to frameworks such as Atlas it is a good idea to learn the nuts and bolts of how and why it all works and learn some basic AJAX coding from sratch, or from "the ground up" as Nitin1981 put it...
I agree with him, there are precious few "clear" articles on this. one thing you can do:
As all the J in AJAX is client side, you can view and download other people's AJAX enabled bits and bobs and see how they've done it! Even if the J is in linked files there are sinple IE extensions you can use to get it.
Otherwise, I found these set of articles, though wordsy, quite good:
http://www-128.ibm.com/developerworks/web/library/wa-ajaxintro1.html[^]
good luck!
cheers

Currently, I am using the DataList to display the data. My DataList code looks something like this:
<datalist>
<itemTemplate>
<tr>
<td>Name:</td>
<td><% DataBinder.....%></td>
</tr>
<tr>
<td>Company:</td>
<td><% DataBinder.....%></td>
</tr>
</itemTemplate>
</datalist>
My question is: How can I have an easy way of sorting this data. I would like the users to be able to sort the data by Name or by Company. I understand I can add AllowSorting to DataList or DataGrid, but then I would have to display the column names and display the data in 2 columns, which I dont want to do.
So is there any other way to allow the users to sort this data, without having to write much code? I am using ASP.NET 2.
Thanks

I have a page "A" in which ther is a table in which i include another page "B" in . I want to use a function of "B" in "A" . Please help me.
|
|
|
|
|
Make the functions of B page public and create the object of B in A's code file and use those functions
|
|
|
|
|
Or a more object oriented and reusable way would be to include the common method in a seperate class, in you App_Code folder if using 2.0, that could be used by both pages.

Hi friends

i want to expand and collapse it without page reload
Thanks in advence
Pathan

|
|

use tree properties and methods
tree.ExpandAll(); // to expand full tree
tree.CollapseAll(); // to collapse full tree
tree.Nodes[i].ExpandAll(); // to expand all sub nodes of i node
tree.Nodes[i].CollapseAll(); // to collapse all sub nodes of i node
tree.Nodes[i].Expand(); // to expand i node
tree.Nodes[1].Collapse(); // to collapse i node
|
|
|
|
|
Use Javascript on the client side to expand and collapse, or use something like the Atlas UpdatPanel.

I can use Server.MapPath to find and read from files on my server; however I can only do this from within the code-behind for a web-page and not a separate class which gets compiled into the application dll.
if I have function within this class/dll that wants to read from an xml file located in the same /bin folder, how do I do it? Is it just a matter of the right import statement in the class, or do I need to use another method altogether?
OK, I could use server.mappath before calling the function and pass the full path as a parameter, but apart from that...
thanks
Fred

use
using System.IO; // for C#
Imports System.IO // for VB.NET
and then try using Server.MapPath
