Hai

If u want to change password as ur design,just get 3 text box values,first check with current password with db and then compare new pass and confirm pass and then update in user table.

If u want to reset password,u need to get new password and user email address,check email address is correct or not with db,and update new password in db and also send new pass word via mail,bca u have user email address.

The above 2 way u can use,all are easy ,just select query ,compare values and update values,in ur project u use all queries why u need codings,just use ur exesting query and chnage little bit.

try this link
select update insert delete commands in c# asp.net[^]

Here we answer specific questions which members face during programming.

We can't work on the whole source code. You need to do that yourself.
If you face any difficulty while coding, feel free to come back here and ask another question with specific issue describing the scenario.

M confused to see "this advice" from a senior member as a SOlution.. :O
Can't it be posted as a comment to OP???

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 10-Mar-14 4:29am

Yeah, but sometimes, comment don't work. When we post this as a comment, others who come to this thread don't bother to see the comment and add another answer. When we add this as an answer, the person seeing the question next does not add an answer; simple ignores it. That is the goal.

Good Logic... Confusion Flown.. :D
