"strbody" needs to be declared outside of the if statement, so that you can access it outside the scope of the if statement.
@{
string group = Model.ArticleGroupName;
string strbody = string.Empty;
if (group.Contains("Spacial Orientation") || group.Contains("Topography") || group.Contains("Osteology") || group.Contains("Angiology") || group.Contains("Neurology") || group.Contains("Myology") || group.Contains("Radiology") || group.Contains("Misc. Drawings") || group.Contains("Clinical Testing"))
{
strbody = item.ShortBody;
}
else
{
string s = item.ShortBody;
string sLess = s.Remove(0, 12);
int index = sLess.IndexOf("Summary");
strbody = (sLess.Substring(index + 8));
}
}
@strbody

Thanks for the response!
I tried declaring the strbody as you suggested previously, but when I did, I got this error:
A local variable named 'strbody' cannot be declared in this scope because it would give a different meaning to 'strbody', which is already used in a 'parent or current' scope to denote something else
Learning C# is really frustrating! I could have done this exact thing with VBScript in about 2 minutes..and 8 less lines of code...

Inside your if statement where it says "var strbody = ..." should now only be "strbody = ..." since you already declared the variable outside of the if statement. If you look at the modified code I provided in my previous post you will see that I am just assigning a value to the strbody variable inside of the if/else statement.

It's working perfectly now...thanks man!

Is there any benefit to adding BEGIN TRANSACTION; and COMMIT; to the beginning and end of a parameterized query in C#. Also, is there any real advantage to stored procedures vs parameterized queries?
For Example:
using (SqlConnection dbConnection = new SqlConnection(GSettings.SQLConnectionString))
{
dbConnection.Open();
for (int i = 0; i < DBUpdateList.Count; i++)
{
string selectSQL = "BEGIN TRANSACTION; UPDATE TABLE SET Dog = <a href="/Members/dog">@Dog</a>; COMMIT;";
using (SqlCommand dbCommand = new SqlCommand(selectSQL, dbConnection))
{
dbCommand.Parameters.AddWithValue("<a href="/Members/dog">@Dog</a>", "Poodle");
dbCommand.ExecuteNonQuery();
}
}
}

Personally I would only use BEGIN TRANSACTION; END in a stored procedure.
If you want to use transactions with your ADO.NET query I would read this MSDN transactionscope[^]

No.
BBatts wrote: stored procedures vs parameterized queries
Those aren't mutually exclusive; even if you use stored procedures, you should still use a parameterized command to provide values (as necessary).
I also recommend that you not keep reinstantiating the Command, but reuse one:
instantiate command
add parameter(s)
(begin transaction if desired)
loop:
set Value(s)
Execute
(commit transaction)

I'd recommend getting a SQL manual, and that's not meant as a snarky remark; programming often involves databases, and you'll need to dig into transactions sooner or later. Life also becomes easier when you can look up what each statement does

Hi,
Did anyone tried Xamarin to develop iOS or Android apps using C#?
How was it?

That's not a specific question.
Yep, I have seen that ThatsAlok[^] recently posted more than bunch of articles[^] on that topic. You could find few more CP members here.
And I suggest you to take a look at Mobile Development[^] section @ Codeproject.

What value is returned in temp?
Do you have the stored procedure code?
A message that something didn't work is not very helpful - you need to debug to find any return messages or error codes

1. Your first 3 parameters are defined as integer but you are passing a string.
2. Why are you converting a Textbox.Text to string? e.g Textbox.Text.ToString()
Have you tried to run the stored procedure directly on the server with some dummy values? if so did it work sucessfully or did it throw an error?

The cmd.ExecuteNonQuery should return the number of rows affected by the command on UPDATE statement in this case if you are getting this message "Your info modification failed " means that for some reason the SP is not updating or is passing null values in the parameters could ya please share the content of the SP that way we can give a more precise solution.

You might want to format your question a bit better - some of that got lost when displayed.

|

you need to explain the problem more clearly!
at a guess I would suggest that you look at the connection objects / strings that you are using to save the data at, I would use that as a starting point to solving this.

I wanna to convert this string :
"
if("2" == "2" && "10" >="9")
return "true";
else
return "false";
if the above string contains any of these :
>= , <= , > , <
Replace the part of string ( "10" >= "9") TO :
( 10 >= 9)
So the final string would be :
if("2" == "2" && 10 >=9 )
return "true";
else
return "false";
How is it possible.
note : the string may contain lot of these math operation in it .

Create a token parser. So, start at the beginning of the string and work your way over it looking for the strings you're interested in. You could do this with a regex and some fancy parsing, but I would keep it simple if I were you. There are some shortcuts that you can take, such as only needing to store the right hand side of the token if the operators are the ones you are interested in. I would also look to split my string up into an array of smaller strings using the && and || operators. Then, I would perform my search on the smaller arrays.
|
|
|
|
|
If the text will contain proper spacing..You may use 'Contains ()'.
<pre>
string strMyText = "There is some text like 10 > 9";
if(strMyText .Contains("10 >9"))
{
strMyText = "I got it"
}</pre>

Okay, two things:
1. The OP does not get notified of answers to someone other than them.
2. Your solution does not even begin to address what the OP has asked for. Take a look at his question again and ask yourself if you have really answered it.
