PadRight will not limit the length it will only pad it.
You example is not correct, but if you did:
String1.ToString.PadRight(6) = "Traile1" you would still get all seven characters. If you want to get only six characters you will need to substring after the padright
String1.ToString.PadRight(6).Substring(0,6)
Hope that helps.

Dear All,
I am mess with one situation let me explain the scenario.
I am making search form where I display 15 field in checkboxlist and user select one or two or three or any no to all field. Depending on his selection (he tick the field and click filter button ) Now in filter button click I create label and dropdownlist control(populated from database) and add it to placeholder control. Now I select value and click the search button. Now in search button I need to access those control and its selected value(ie label and droplistbox ).
I have made function to create label and dropdownlistbox which is
private void createcontrols()
{
foreach (ListItem li in CheckBoxListmst.Items)
{
if (li.Selected == true)
{
//code added to fetch dropdownlist
setting = ConfigurationManager.ConnectionStrings["StyleSearchConnectionString"];
if (setting != null)
{
Code to access data for populating dropdownlistbox
try
{
// added controls
Label label = new Label();
DropDownList dropdownlist = new DropDownList();
label.ID = "label" + i.ToString();
dropdownlist.ID = "dropdownlist" + .ToString();
i++;
rdr = cmd.ExecuteReader();
while (rdr.Read())
{
Items for dropdownlist
}
PlaceHolder1.Controls.Add(label);
PlaceHolder1.Controls.Add(dropdownlist);
}
catch (SqlException ex)
{
}
Now this create function I call in one in filter button click event and second as
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
createcontrols();
}
Now in seach button click event when I am trying to access
Code is
Label objlbl;
DropDownList objdrop;
objlbl = this.Page.FindControl("label1") as Label;
objdrop = this.Page.FindControl("dropdownlist1") as DropDownList;if ((objlbl != null) && (objdrop != null))
{
cmd.Parameters.Add("@para1", SqlDbType.VarChar).Value = objlbl.Text; //Page.FindControl("label1").ToString() ;
cmd.Parameters.Add("@value1", SqlDbType.VarChar).Value = objdrop.SelectedValue;
}
I am getting objlbl and objdrop as null.
Please help
thanks

You will have to search the PlaceHolder control and not the page. You will have to do a PlaceHolder1.FindControl(controlid)
Label objLabel = PlaceHolder1.FindControl("Label1") as Label;
DropDownList objDropDown = PlaceHolder1.FindControl("dropdownlist1") as DropDownList;

FindControl() should return the control. Did you debug and check if the PlaceHolder contains the controls? Debug and check the id of the control's that are in the PlaceHolder.

You may need to call createcontrols() from Init rather than OnLoad. The problem is that on postback, the values in your checkboxes are saved in viewstate, which gets applied between Init and Load. If you wait until Load to create your controls, the viewstate won't be applied to them, and they'll lose their values.

i change the code and put it in Oninit as
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
createcontrols();
}
but still oject are null....
please help

My fix isn't for the problem you have (objects are null) but for the next problem you'll encounter (objects won't maintain values on if you dynamically create them too late in the page cycle).
The other solution posted to search the placeholder rather than the page for the controls should work, so I'm not sure what's wrong. I would use the debugger to inspect the contents of the placeholder's controls to see if anything is there.

I have aspx pages sitting in two different folders and both are mapped in virtual directory. I want to use response.redirect. How would I go about doing that?

Hi, I have a slight problem with getting records from a database.
The problem is simply when I use the following SQL string, it throws me up an error message.
Problem string:
"SELECT * FROM IDs WHERE id='2'"
However when I use this SQL string, it works.
Working SQL string:
"SELECT * FROM IDs WHERE name='bob'"
I have no idea why one is working and the other isn't. The only thing I could think of is a type mismatch (The id field is set to AutoNumber). I get the same error when trying to use both Strings and Integers.
Anyone have any ideas?

Ahhh goddammint!
I figured out what the problem was.
I was using "SELECT * FROM IDs WHERE id='2'" when I should have been using "SELECT * FROM IDs WHERE id=2".

Have you tried:
"SELECT * FROM IDs WHERE id=2"

Hello All,
Need your help with regards to SSO(Single Sign On). Lets say I have two websites A and B. After user logs on to A(login.aspx) user needs to go a say a default.aspx page and on Default.aspx, there is a button which on click should send the user to website B,(both websites are on the same domain..lets say a.abc.com and b.abc.com) as user is already logged on site A..it should directly send the user to welcome.aspx page on site B. Iam using form authentication. This is what i have in my web.config on both sites.
<authentication mode="Forms">
<forms name=".SSOAUTH" loginUrl="Login.aspx" protection="All" path="/" timeout="30"/>
</authentication>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
<machineKey validationKey="1234567890" decryptionKey="9876543243" validation="SHA1"/>
On my site A login page, when user enters a login and password, i call a function and go against my DB and validate, if login and pwd match db, i return customerid and the code is as below:
Dim customerid As String = ValidateUser(txtUserName.Value, txtUserPass.Value)
If customerid <> "0" Then '--------Comment-if login is fine, customerid is never 0
Dim tkt As FormsAuthenticationTicket
Dim cookiestr As String
Dim ck As HttpCookie
tkt = New FormsAuthenticationTicket(1, txtUserName.Value, DateTime.Now, DateTime.Now.AddMinutes(30), True, "your custom data")
cookiestr = FormsAuthentication.Encrypt(tkt)
Session("FormData") = cookiestr '------Comment-saving in session for later use
Dim b As String = FormsAuthentication.FormsCookieName
Response.Cookies(b).Domain = .abc.com
Response.Cookies(b)("SiteA") = cookiestr
Response.Cookies(b).Expires = tkt.Expiration
Response.Cookies(b).Path = FormsAuthentication.FormsCookiePath
Response.Redirect("default.aspx")
Dim strRedirect As String
strRedirect = Request("ReturnURL")
If strRedirect <> "" Then
Response.Redirect(strRedirect, True)
Else
strRedirect = "Default.aspx"
Response.Redirect(strRedirect, True)
End If
Else
Response.Redirect("Login.aspx", True)
End If
My problem is it never redirects to Default.aspx on Site A... and from default.aspx on Site A..if i click a button..i need to it go to welcome.aspx on site B... for some weird reason though, it goes back to the login page..and further.. the cookie is set..its not reading it on site B. Please Help !! Any help is appreciated, where am i going wrong? code samples are much appreciated.

Hi ,
I am trying 3rd party authentication in my web application.
I am trying to use Google, Yahoo, AOL authentication providers. These authentication processes I am using to authenticate my application. I've done authentication for GMAIL.
In this authentication I've done following steps
1.Registered in GMAIL and mentioned destination page for remote authentication.
2.Used URL of Gmail authentication in my code and redirected to it
3.After entering correct credentials I retrieve TOKEN
4.Extract this TOKEN in destination page which I've mentioned in 1st step and with that Token I am calling Web service of GMAIL and retrieve User Details form it and showing on that page.
It is working fine for GOOGLE but from nowhere I am getting process/steps of how to use third party authentication for OPENID.
Please tell me if you know how to authenticate it.

Hi All
I have created a folder which I want to rename through coding. If some knows the procedure then pls help me.
thanks in Advance.

|

|

Use the System.IO.Directory.Move or the System.IO.DirectoryInfo.MoveTo method.

Hi,
I think the possible way to rename the folder is to delete the folder and create the new folder with the new name, before deleting the old folder we should move he contents of that folder to new folder.
Regards,
Sandeep Kumar.V

System.IO.DirectoryInfo dInfo = new System.IO.DirectoryInfo(Server.MapPath("1"));<br />
if (dInfo.Exists)<br />
{<br />
System.IO.Directory.Move(Server.MapPath("1"), Server.MapPath("2"));<br />
}<br />
I just tried it.Its working fine
Here "1" is folder name
Best Regard
Khan

Hello,
I’m writing a web application that needs to access other web applications. The pages that I need to access use both windows and forms authentication. I need to authenticate the users of my application without prompting for their password a username (they have a password and a username and I’ll use them to log in automatically).
I’ve already made this process for the applications that use forms authentication by making a POST request programmatically.
I need to do the same for the applications that I need to access that are using windows authentication, but I have no idea. Can anyone help me? Thanks.
