View 4 RepliesI have a list XML elements that I need to compare to chars in an array. Some of the XML elements start with uppercase characters and some dont.
So I need to convert the XML elements to lowercase to compare them against "alphabet".
I'm doing this by converting the XML element to a string. Then setting that to lowercase. Then converting that to a char. Then comparing that to each char in "alphabet".
Is there a better way to get the XML into lowercase? IE without the two conversions

how to change
XXX@YYY.ZZZ into XXX_YYY_ZZZ
One way i know is to use the string.replace(char, char) method,
but i want to replace "@" & "." The above method replaces just one char.
one more case is what if i have XX.X@YYY.ZZZ...
i still want the output to look like XX.X_YYY_ZZZ
is any meaning of # char in page url... u can see this in below [URL] see in last #tile=outlook...
View 12 RepliesI am using SQL Server 2008 Web Edition and it seems my SQL queries are automagically having the double quotes replaced with ' + CHAR(34) + '. I am trying to pin down why this is happening, I am using Delphi with ASP.NET and using the ADO.NET object for the SQL.
Has anyone come across this before?
When I try to run the following code it always spits out the hex representation, not the integer representation. Most of the examples I found on MSDN said this should work. What am I missing?
var stringBuilder = new StringBuilder("8");
int j = 0;
foreach (char item in stringBuilder.ToString())
{
j = Convert.ToInt32(item); //returns 38, need return to be 56
}
edit I should have made clear that I know the difference it's returning the hex value. I'm outputting the value to a file, and in that file, it still shows the hex value, not the integer, so I don't think it has anything to do with the debugging environment. edit2 Looks like a PEBKAC problem. Looked at the code that was writing to the file, and it was using a .toString("X") method, changing it to a Hex value. The fact that it was hex in my debug environment was what confused me.
i wanna convert char to double type and convert it to date.char->double then double -> date type.I have a whole string and i trim it into 3 parts. In my item(2) is a UNIX Timestamp i'm trying to convert it into date type.

I use asp.net + MVC1.0 and in a webpage I have several forms, within each forms I have called the following function

When I use JMeter and capture the token using regular expression then post the token with my form to server, I found it throw such a exception:

I am building a page which has to search an access table with the text input entered by the user. The thing that is puzzling to me is that the functionality works only when a '%' is explicitly added to the text input at the begginning and end.
If I add '%' programattically in the code behind file, it does not work.
code snippet ( asp page):
<asp:AccessDataSource ID="AccessDataSourcex" runat="server"
DataFile="~/App_Data/company.mdb"
SelectCommand="SELECT [ID], [emp name] AS emp_name, [emp title] AS emp_title FROM [EmpMain] WHERE ([emp name] like [code]...
//the below line is of no use, the % char has to be in the text input
//txtSearch.Text = "%" + txtSearch.Text + "%";
GridView1.DataBind(); <---- this works fine
<--- this does not work, even if I add % chars programatically..
My question is: why does it not work when I programattically add the '%' chars to the search string..
What are the basic difference between the char and varchar datatype ?
View 5 RepliesI'm using DAAB from MS Ent Library 4.1. I have this function in my DAL that returns a dataset.
[Code]....
However, it is failing with this error:Failed to convert parameter value from a String to a Boolean.
But if I use SqlDbType.VarChar instead it works fine. I want to use Char b/c that is the correct datatype in SQL.In my SP the param is @CUSTNMBR char(15). In my database table the field is also char(15).
Let's say I am pulling data from SQL using a function that returns one field - date. I can see that in my model code for a getter, setter, and other things are set for DateTime. What happens if I go into the function and convert selection of my date field into char(10)?
View 6 RepliesI have the following string stored in a char column of sql server (there are several this one is just an example):

I also have the key used to generate the string:

And I found the following solution to decryp and encrypt:
Code:
Dim des As New TripleDESCryptoServiceProvider
Dim md5 As New MD5CryptoServiceProvider
'hash function
Function md5hash(value As String) As Byte()
Return md5.ComputeHash(ASCIIEncoding.ASCII.GetBytes(value))
End Function
[Code] ...
It works like a charm when i encrypt and decrypt values set by me in the page;
But when i use the value stored in the DB it throws the following error;
"An exception of type 'System.Security.Cryptography.CryptographicException' occurred in mscorlib.dll but was not handled in user code
Additional information: Bad Data."
I am i using the wrong crypto class ? it's a length issue? the string is not base64?

I have a problem that if I pass a string that contain + in a query string and try to read it , it get the same string but by replacing + with empty charFor example if i pass query like ../Page.aspx?data=sdf1+sdf then in page load I read data by data = Request.QueryString["data"] it will get as below data ="sdf1 sdf"
I solve the problem by replacing any empty char with + .. But Is there any problem that cause that ? and Is my solution by replacing empty char with + is the best solution in all cases?

I am having a problem about my gridview when it binds to an accessdatasource.
The error appears:
"DataBinding: 'System.Char' does not contain a property with the name 'Firstname'."
Here's my gridview:
[Code]....
Here's my code behind:
[Code]....
The error occurs when the selected index of the DDL is 1 and I have to bind it in an accessdatasource. First condition is working fine where I will check a value and put all items that matched the date criteria in a data table and then bind gridview in the data table.
The error is just when I bind my gridview in the accessdatasource.
AccessDataSource1.SelectCommand = "Select Firstname,Middlename,Lastname,Jobseeker.IdNo,SchDate,Time,Venue,JobPosting.JobCode,JobTitle from JobPosting INNER JOIN (Jobseeker INNER JOIN ApplicationProgress ON Jobseeker.IdNo = ApplicationProgress.IdNo) ON JobPosting.JobCode
= ApplicationProgress.JobCode where PostingHr = " & Session("Id") & " and SchDate = '" & Date.Today.ToString("dd - MMM - yyyy") & "' "
GridView1.DataSource = "AccessDataSource1"
GridView1.DataBind()
