You didn't mention `.` (single quat), is this not need to used?

ok,thanx for reply

Label,button,dropdown visible so, why not chart?

Ok, thanks.

I don't want to use two event handlers,thats why it is better choice to go for textboxchanged event. sorry for late reply.

Its not working

Ok,Sorry for that. Is there any solution for this?

Is not possible with label?

Yes Sir Looking for same but in Windows From application.Is JQuery applicable for winforms?

label arise label_Click event when double click on label. I want label textchange event instead.

This xml file is added to master page by using xmlDataSource such that it look like menubar. My question is can i perform click on xml contains/items? by which i can nevigate to other page.

if i dont wan't to specify directory name i.e. "D:\... " directly just file name filename.xls @E.F.Nijboer

this is a winform application

whole code is in tags its giving an errors.
its giving error like => The resource cannot be found.

and what to do if want to use c# code into view like,

@using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl })) {
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)

I already did this,its not works.

f9 :)

after right click on view folder and add new item then it gives webforms option to add and after adding it it come with .cs file.

Ok,thank you very much.

but there is some control? because without that how they launch new version like MySQL 5.6.0 ?

will you please tell me about what is file-stream and log files and role of those in sql server express database? and is sql server management studio 12 free?

thank you..

thanks for suggestion. may you give knowledge about how database is handle when exceed than 10GB in sql server express, please.

I found some limitations as follows, Is there some which I missed compare to other sql server edition?

1)Buffer pool extension to SSD
2)Backup encryption support
3)Disaster recovery to Microsoft Azure

It support 10GB of database then what will happend when data exceed it. then is it haddle by file system?

My database is big enough, then what would you suggest me from Sql server express edition and MySql(as its all n complete version is free).

thanks for answer.

Thank you Mika.

yes sir google is what we learned from and it is to give reference that's why I mentioned it.
Will you please explain following formula to calculate the raw data size (mathematically)with example, It will be great-full and easy to understand for me:

Like:
No of Devices=50
No of readings= 69 per device....

Formula:
devices*device sensors*readings per year*years*record size

And one point is when I shift my database on cloud then is it give a solution to increasing size of database? as they provide storage space by paying for it.

thank you my most of points clear now.

then how google deal with continuous increasing data(Big data)? Is they increased physical storage capacity?

Thanx for reply, Honestly speaking its really tough for me to understand because this is completely new for me, I learned and work with Sql server,Mysql. just creating a database and access it. But never thought about next problem when data increased in big quantity.My general thought is that for such application such problem faced then they simply increase the physical storage device size where database store or make it small(in simply say ZIP it).

so sir, please understand my level and try to make your explanation easy to understand me.

MS SQL server size is 10GB or it is depend on O.S. and system storage capacity? I think its Hard-Disk storage capacity of system.

a lots of silly question arises in mind but answers are always confusing.

once again thank you for reply.

Sir please reply, mainly for last question, How can someone properly handle that size over time?

Hello Zoltan Sir,

Thank you for guidelines, Now I got what to ask.
about my database:
1)About is the frequency: one reading per second
2)yes,This continuous reading 7/24/365
3)I don't know about batch inserts,continuous granular inserts but when I search on net then from that little info. I think I don't use it, I fired insert query after time interval means 1 sce, 5 sec, 1 mint.
4)how big your database will grow? => It is grow up-till device send data to it.May be continuously for 3-4 years. It is interrupted only by if power supply is off of device, and power is on then it start reading data again.
i)indexes? => which indexes?
ii)transaction logs => transaction logs are maintain in txt file.

5)finally: How can you properly handle that size over time?
This 5th question really matters for me, because I do not have any idea how to deal with or handle the long/big size of database.

please give me detail information specially for 5th question.

Thank you once again for make me way to put my question in well manner.

ok sir, thanks your suggestion always helps.

Sir, Requirements are database is for taking a continuous readings from devices located at different locations(database is serverside). for each device separate table is maintained. reading parameters are 100 for each devices. after that analysis will be done on database entries.
The question is just because of Asp.MVC or asp.webforms are product of microsoft and ms sql server also. that's why one thought i always listen they are made to work efficient with each others where as mysql is from oracle.
Sorry if my question is silly .

yes sir that's what issue i am facing now.have a lot of code and logic in the aspx.cs pages. ok now i am making it modeler first. then go for MVC.

thanks to you and all for valuable suggestions.

so what would be u r suggestion sir, go for MVC or make existing one in three tire?

thank you once again.

Use of three tire architecture is same as MVC if we consider just coding part not front-end or is it affect a performance? Which tool should I used for checking performance of my project(web app)? Now the fact is this is my senior's project now handover to me, and he did a complete plain coding i.e. No use of moduler programming,he wrote a code like one aspx page and its .cs file contain 8000 of lines. same for all other pages.
thank you for u r time and reply.

aarif sir please reply. how many months i required? as I am just start today with MVC. it's urgent. I know its also depend on me. but i want suggestion from experience person.

how many months i required? as I am just start today with MVC.

Sir I go through most of links also WebForms vs. MVC[^]. but at final conclusion is both can't replace each others. and questions also provided that to choosed which one. but I am completely new in MVC. so which one is good? MVC as aarif said?

ok i got it. thank you once again.

Sir I go through following site/blog they mixing mvc and webforms. so is this possible?

https://www.simple-talk.com/dotnet/asp.net/mixing-web-forms-and-asp.net-mvc/

http://www.hanselman.com/blog/IntegratingASPNETMVC3IntoExistingUpgradedASPNET4WebFormsApplications.aspx

thank you sir.

ok, thank you sir

yes sir it is ASP.net web application,front is same as u tell.

1)yes sir it is depend upon your capability by seeing the requirement document and getting understanding about web application but Please tell me general type of question to ask? because I am coder ans uptill not interested in frond end design and look n feel of web app. but it will be better u mention some types of general questions.

2)some rules may follows,may not specific. but tell me general ones.

thanx for reply.

to call QueryFunModbusRTU method directly i have to use any event like button click that's what you said,Right? to call this by click event i have to fire click_event directly. but i have to first execute Reconfigure_Done_Editing_click method,then CreateThread() without user interference and then QueryFunModbusRTU() this one. is u want to say that call click event of button in method Createthread() then problem is again same how to call event in web-method?

i can't, because all depend on each other, must follows flow.

[source code.aspx]
<div class="popup_Buttons">
<input id="Reconfigure_Done_Editing" value="Done" type="button" style="visibility: hidden; width: 10px;" />
<asp:Button ID="Button5" runat="server" Text="Done Editing" OnClick="Reconfigure_Done_Editing_click" />
<input id="Reconfigure_panel_Button_Cancel" value="Cancel" type="button" />
</div>


.cs code:

#region Reconfiguration
public void Reconfigure_Done_Editing_click(object sender, EventArgs e)
{

Createthread();
}

[Web Method]
public static void CreateThread()
{
QueryFunModbusRTU();
}


#region Modbus_RTU
[Web Method]
public static void QueryFunModbusRTU()
{
if()
{

}
else
{
*HERE I WANT TO SHOW MESSAGEBOX
}
}

hi,

there are two web methods 1)Createthread 2)QueryFunModbusRTU which are call on click event of public void Reconfigure_Done_Editing_click(object sender, EventArgs e)

first Createthread() this web method is called and then this method call second web method which is QueryFunModbusRTU now in this method contain if else and i want show message in else part.

i tried to implemet javascript/jquery/ajax call for alert message, but question is this javascript function also required click event to execute we can't call the javascript from web method i think, if we can then plz tell how? or any other solution plz tell same.

please tell me ajax success. how to use.

simply i took label and show message in it. but still its firing a error of
"Object reference not set to an instance of an object."

i am accessing label from different webform. like this

Trends fc = new Trends();
string str = "Check device";
fc.Label3.Text = str;

where Trends is a other from in which label3 declared.

i find it. but i did't want to use any event like clink. I want to show message through web-methode only. is there any other way to do this?

please tell me how to do that.
and Ajax call?

sorry i m not getting, may you post the code plz. thanx

yes inside a Web Method
public static void QueryFunModbusRTU()

Keyword 'this' is not valid in a static property, static method, or static field initializer this error is fired when execute this line ScriptManager.RegisterClientScriptBlock(this,this.GetType(), "alert", "alert('Your Message');", true);

and about below line

System.Web.HttpContext.Current.Response.Write("<script>alert('Item Already Exists')</script>");

i did not use any variable. what is alert('Item Already Exists') is alert is user define fuction and must be define esle where?

and at this line exception is at:

System.Web.HttpContext.Current <= at this point its show null.

thanx for u r value able time.

means is there need to write script at page.aspx soure code? or <script>alert('Item Already Exists')</script> this is enough. because i did not written at source file.

thanx DamitSL for reply
