Hi All,
In C#, How To Send A Hyperlink Using Query String Method.
I have developing a web application of user enter enters the personal data. That information has sent to admin mail with approve/reject link button.
When the Admin click the approve link, it has approve.aspx page with the user id as query string to update the db as approved. otherwise rejected.
I can try the following code.
mail.Subject = "New User";
mail.Body = "<p>Dear Sir, <br><br> " + txtfname.Text + " " + txtlname.Text + ", has raised a requisition that needs your approval. <br><br><br> Please click to [<a href='http://localhost:1240/IMA/Approve.aspx?id="+tt+"'> Approve</a> ] [<a href='Reject.aspx'>Reject</a> ] the request. <br> <br> <br> <b>Note</b> : Please do not reply. This e-mail has been auto-generated.</p>";
mail.IsBodyHtml = true;
In the mail i have move the mouse over the approve link it shows http://.../approve.aspx?id=1, but click the appove link
it shows <a href="http://.../id=1.
I don't know why.
Please help me out.
Thanks in advance,

For a C# 2010 application, I need to check for the values in a column being all spaces. The number of space characters in a field can change. Thus can you tell me how to tell if a field in a string and/or a datadbase column is all spaces?
|
|
|
|
|
This is stimple string manipulation. Every string has a Chars array. All you do is iterate over the array and compare that character to " ".
|
|
|
|
|
One way to do it would be to use the Trim() method of the string, and if the resulting string is zero characters in length, then you know it's all spaces:
if (myString.Length > 0)
if (myString.Trim().Length == 0)
return true;
The difficult we do right away...
...the impossible takes slightly longer.

how to get all the tables from a particular database in c# codes???
|
|
|
|
|
|
Try:
SELECT column_name, data_type, is_nullable, character_maximum_length FROM information_schema.COLUMNS WHERE table_name='myTable'
Or
select column_name from information_schema.columns where table_name = 'Test'

You haven't said what the problem really is, so how do you think we can help? You need to debug your application and try to narrow down what is happening yourself.

I was thinking about a software that can send messages without connecting any phone to your computer. You just have to register your number and than receiver's number and message will be send using your GSM services. If you know what i mean. It will use your phone's credit there is no role of phone physically. I am thinking about using c#. Help if someone can help me.

Help with what, exactly? All you have is a description of what the software should be able to do. No-one will write the software for you; if you want this idea to become reality, you'll have to start writing code. If you get stuck and have a specific question, we could help. "Help" means a pointer in the right direction, not "writing lots of code based on a vague idea". FWIW, I'd recommend researching whether what you want is technically possible.
I do not own a mobile phone, so these might be non-issues to you. Still, I'm wondering how this would work with a prepaid-phone. How will you perform a transaction without physical access to the phone?
Even without prepaid, let's assume a subscription. How would you know who my provider is, and how would you do a financial transaction on that? I bet it's not going to be easy, otherwise a lot of people would simply be stealing credits, wouldn't they?

I think you are right - at the very minimum you would need the IMEI number I assume. Sounds a bit "iffy" to me - would probably need to be discussed with the carrier companies before you could go ahead with it.

I am working on setting up a C# 2010 application that will search directory file paths to see when there has been a files added
to the directory since the last time the directory was searched. I basically want to look for the following:
1. files that end with *.xls or *.xlsx.
2. I will look for files in the 'highest' level directory path and serach for new files that have been added since the last time the search was made.
Thus I am hoping you can tell me how to accomplish this goal and/or point me to referneces that will let me how to accomplish this goal.

I foresee a Sqlite-database (or similar) that holds all those names and the date/time they were encountered. Ideally, it'd also provide a hash-value of it's contents.

Did you have a database-structure in mind for that?

Directory.GetFiles()[^] will help you find the list of names in the directory. From there you can check details such as date created etc.

How do you tell when a new file has been added to a selected directory path?

rachel_m wrote: How do you tell when a new file has been added
You can either keep a list of existing files and compare with that, or check the creation date to see whether it is newer than the last time you searched.
