how to send sms from asp.net application to mobile
Hi,
Sorry for late reply. For sending sms from asp.net application to mobile, we have to take help of “Sms Gateway” which will be provided by some other company. That will be payable. There are so many service provider for Bulk sms. They will give the “Developer Api Code”. We have to do little bit modification on that code then we can implement in our application.
For testing this functionality, you can refer this site
http://www.clickatell.com/products/sms_gateway.php
and you can also read this thread in asp.net forum for more detail.

Hi,Chandra
How are you?,How can i get image into gridview which is stored as a binary formate in the database,I got some extent using handler but image was not coming,Please give me idea,Moreover i want only single record using only selected person name,based on the person name only i will get the data.
Thanks
Chakri.
Hi Chakri,
Sorry for late reply, I was some more busy in last week.
You donot follow this approach to store image in database. If you are going to display more image at one time from database then it will very slow.
Before 1 yr i had written one artical, you do like this
https://chandradev819.wordpress.com/2010/07/10/how-to-store-imageurl-into-database-and-deleting-image-from-image-folder/
If you will get any problem then feel free to ask. I will send reply quickly.
Hello Sir
i am create s website sms gateway
how can we implement group sms in our applcation and how can send sms from our website to mobile no
Hi Suresh,
I hope that you are aware of sending sms to single person. For sending sms to multiple Users fetch the all mobile No from database using sql query or LINQ. Then store it in datatable or list and keep there some loop like for or foreach in datatable or list. Then sms will go to multiple users.
If you have still problem then fell free to ask with me.
Hi,Chandra

Sir,
I Have doubt on MySQL query(i.e) ‘m using a query like
Delete * from NoteAttach where N-Id=(select ID from Note where B-id=2);
but the problem is B-id=2 has its N-Id values 1,2 . here only the id’s 1 are getting delete but not the 2. so what query can i use for this.
Hi
If You have to delete multiple record at one time then you can write like
Delete from NoteAttach where N-Id in (select ID from Note where B-id=2);
I m sure, this will work in sqlserver. But in Mysql, i don’t have tested, Please test it and confirm me.
Hello can you tell me about database connectivity in C# .NET & ASP.NET & how to show data on particular page or form

hello sir,
after long time i required your help,i read your 3 tier application article which is too good but i have some problem in 3 tier architecture i have the requirement insert data through footer in gridview from two tables using stored procedure.First table is employee column name empcode,name,departmentid and designation and second table is department column name is departmentid and departmentname,where empcode is in the form of “emp001” which is primary key and department id is primary key in second table.And it also perform update,edit and delete option.In gridview it shows column empcode,name,desigantion,departmentid and department name.
Hi Rahul,
This is straight forward. You create 2 tables i.e tblEmp and tblDept i.e in tblEmp you give EmpId as PK,
EmpName,EmpDetails and DeptId as FK. In tblDept you can give DeptId as PK, DepName etc. where tblDept is master table.
you save all the required information with DeptId in tblEmp. You can also delete that record with EmpId.
if you are still getting the problem, please let me know where are you getting the problem?
