Hello all.
I'm trying to implement something but since I'm not sure if it's possible (and also because I don't know very well this area) I'm getting some dificulties. Maybe someone can help me.
I have the following scenario:
1 webserver with a portal application
1 webserver on a diferent network and location with another web application
My users access to the portal application and authenticate with theis own login and password.
Next they have available on the portal one link to the other web application which they click and access to it.
Since the other application is also protected with forms authentication, I need to know the users when he first access to the other application (it's similar with single-sign-on).
I need to call from the portal one webservice that is located in the other application. Then this webservice authenticates the user (user details are sent on the webservice call) on the other web application and return only an OK to the portal.
When the user click the link, he is redirected to the other application and is already identified automaticaly.
Is someone here that already do anything like this ?
Does anyone know if this is possible ?
Thanks in advance for your replies

I'm using vs 2002 and the other day, I was suddenly no longer able to debug my asp.net web project. I receive the following error when I try to debug:
--------------------------------------------------------------------
"A project with an Output Type of Class Library cannot be started directly. In order to debug this project, go to the Debugging tab under Configuration Settings in Project Properties, and set the Start Action to Start External Program or Start URL. Alternatively, you can add a non-library project to this solution that uses a reference to this project and set it as the startup project."
----------------------------------------------------------------------
I tried following those instructions (even though I wasn't using "Start External Program" or "Start URL" before and everything was fine then) but I'm still receiving the error.
I don't know what it is that I've changed in my project to force this error to appear. Any ideas on how to correct this?
Thanks in advance.

I had this happen to me the other day and it drove me crazy until I realized that somehow another project in my Solution had been set as the "StartUp Project" (aka, the project that is run when you click play). Just right-click on the REAL project from Solution Explorer you'd like to start and choose "Set as StartUp Project"... The selected project will be bolded to confirm. Yes, it is frustrating that it seems to override the startup options on the Project Properties dialog, caus that's where I checked first too. hah.

That was it. Thanks swilly1!
lol
To try to resolve this problem, I was looking into changing values within some vs.net XML files and I had already removed all changes I made to my files the day this issue happened (I saved a copy of these changes though)....it's just funny how my largest headaches always turn out to be fixed through the click of a single button.
Thanks.

I am trying to use the ICallbackEventHandler interface.
I create a callback function as below:
string src = Page.ClientScript.GetCallbackEventReference(
this,
"arg",
"ClientCallback",
"ctx",
"ClientErrorCallback",
false);
string mainSrc = @"function PrintComplete(arg, ctx)
{alert(arg); " + src + "; }";
Page.ClientScript.RegisterClientScriptBlock(
this.GetType(),
"PrintComplete",
mainSrc,
true);
Now I add a button to my page and hook it up to a click event handled on the page along with the callback funtions.
test
function ClientCallback(result, context)
{
alert(result);
}
function ClientErrorCallback(error, context)
{
alert("Error in callback");
}
function test()
{
PrintComplete(5, "test");
}
This all works fine. Now if I try to call the test function from another script created with RegisterClientScriptBlock I get the call into PrintComplete but no call back to the server.
Any ideas? Is there a difference when running a script on the page versus a RegisterClientScriptBlock script?
Thanks,
Todd

If you run code from a block created with RegisterClientScriptBlock, the code will run while the page is loading. The only things that are available at this time is in the code above the script.
There are three possible reasons why the postback doesn't work:
:: The function for callback hasn't been written to the page yet.
:: The form fields used by the callback hasn't been written to the page yet.
:: The form is not fully loaded, so it can't be posted.
I don't know exactly which of those three that is the actual reason. Either way, the reason that it doesn't work is that you are trying to make the postback before the page is complete.

 Hi,
I am Ravindra ,new to ASP.net and when I tried to work with adrotator
adds are not displaying with moving banners ,they are displaying just
like an ordinary image .
please, anybody help to work with adrotator (with moving
banners).

hi,
Ravindra adrotator provided in .NET studio doesnot provides you the feature you are looking for. In .NET adrotator, images are changed when the page is refreshed.
If you want this functionality that the images change automatically, then you have to use javascript( Preload images) or Ajax.
Thanks

Hi
I have developed a site of Sale/Purchase of Vehicles. We put vehicle's information on other site like greatvehicles.com, ebay, vroom.com etc.
Now when a user update its Vehicle Information from his account I need to keep track what information he has changed(eg Make, Model, Photos etc). I need to keep last 5 updates made by user.
Please suggest me any koool suggestions to handle it. Please let me know if you need further information regarding this.
Thanks in advance
Lets work it Out.........!

create a table on database say vehicle_history (the fields that you need to keep track of and a number showing the history id)
create a update trigger on original table and insert (if the number of records for that vehicle is <5, or insert + delete the oldest or the one with smallest history id).
Thats it...

I am writing an application that uses Web Parts that are controlled via custom editor drop down lists. The problem I have is in getting the new data to be saved in the personalized DB. The Personalization state is set to 'shared'.
Do I need another class to read the new variables and save them to the DB?
Thanks in advance for any help or suggestions.

Hi there....
I have a page in which i have several usercontrols. In some of the usercontrols I am generating checkboxes, textboxes etc for x number of customers to capture their details. in my main page, i would like to retrieve the values that are posted. I have attempted to use Page.FindControl(...) however i keep getting object not declared. Since the controls are dynamically created, .net creates for example an arbitary name "ctl00_cphBookingWizard_ucPassengerProductConfigure1_UcPassengerProducts2_gvwProducts_ctl02_chkInclude"
for a checkbox which is id'd by chkInclude in my code.
My question(s): 1. Is there a way to retrieve dynamically generaty controls such as checkbox if .net appends to the control id?
2. DO i have iterate through the page to do a control compare in order to capture the values i need (really not efficient way of doing things!)?
Tx

You would be better to place properties on the user controls that contain these controls to find the values. Or you can use myUserControl.FindControl to find the controls within them by their design time id.

I have a nested datagrid. Because of the way the information is set up in the database, I have separate SQL queries to populate the grid:
private void BindData()<br />
{<br />
strPartNumberInputReference = txtPartNumberInput.Text <br />
string SQLString = "SELECT p.PartNumber, p.ID as ptID, pt.description, dd.DrawingNumber, dd.DrawingRevision, dd.DwgPath FROM parts p INNER JOIN PartTypes pt on pt.ID =p.PartTypeID LEFT JOIN DraftingData dd on dd.PartID = p.ID WHERE p.PartNumber = @PartID;SELECT w.weight, wt.Description AS wtDescription, p.PartNumber from weights w INNER JOIN weighttypes wt on wt.ID = w.weighttypeid INNER JOIN Parts p on w.PartID = p.ID WHERE p.PartNumber = @PartID;SELECT c.cost, p.PartNumber, ct.Description AS ctDescription from Costs c INNER JOIN Parts p ON c.PartID = p.Id INNER JOIN CostTypes ct on ct.Id = c.CostTypeID WHERE p.PartNumber = @PartID; SELECT s.SubPartID, s.Quantity, s.Sequence, p.PartNumber FROM SubParts s INNER JOIN Parts p ON s.PartID = p.Id "; <br />
SqlCommand cmd = new SqlCommand();<br />
cmd.Connection = new SqlConnection(strConnectSQL);<br />
cmd.CommandText = SQLString;<br />
cmd.Parameters.Add ("@PartID", strPartNumberInputReference);<br />
SqlDataAdapter adapter = new SqlDataAdapter(cmd);<br />
adapter.Fill(ds);<br />
<br />
ds.Tables[0].TableName = "Rest";<br />
ds.Tables[1].TableName = "Weights";<br />
ds.Tables[2].TableName = "Costs";<br />
ds.Tables[3].TableName = "Subparts";<br />
<br />
<br />
dgParts.DataSource = ds;<br />
dgParts.DataBind();<br />
txtPartNumberInput.Text = "";<br />
<br />
<br />
}
Using these separate table names is how I populate the three nested datagrids.
I have a button for the user to click to add a new blank row for the main datagrid (called "Rest"). I've been messing with it for several hours and get one error or another.
Currently I have:
private void add_Click(object sender, System.EventArgs e)<br />
{<br />
DataTable dt2 = ds.Tables["Rest"];<br />
DataRow row;<br />
row = dt2.NewRow();<br />
row.ItemArray = dt2.Rows[0].ItemArray;<br />
row["PartNumber"]=strPartNumberInputReference = txtPartNumberInput.Text;<br />
row["DrawingNumber"]=DBNull.Value;<br />
row["DrawingRevision"]=DBNull.Value;<br />
row["DwgPath"]=DBNull.Value;some additional code...
but I'm getting the error "There is no row at position 0."
How should I be programming this?

|
|
|
|
hi,
its probably because you are creating the new row but not adding it to the table.write dt2.Rows.Add(row)

try telerik treeview component... they are really working nice and fast... You can find the documentation and tons of running samples...
Here is a part from documentation (r.a.d.treeview Client-Side):
FindNodeByText(text) Returns the first instance of a node with the specified Text.
FindNodeByValue(value) Returns the first instance of a node with the specified Value.
