In that case you can go for page methods.

Hi
I'm new to crystal reports.I am developing a web application which generates reports . I'm using Crystal Reports XI developer edition to generate reports. How do I deploy the web application in the server along with the Crystal reports. How to take care of licensing of crystal reports in the deployment. Is there any restrictions such as number of users accessing the report at a given time
This web application is a Internet application(not an intranet application). Any help is appreciated.
Thanks in advance,
Harshini.

Hi guys
I'm fairly new to ASP.NET, so I'm sorry if this is a silly question...
I was wondering if anyone knows if there is a way of having a nice, smooth colour change effect on a section of header without using flash? I was thinking of maybe an animated giff, but it may need to be a bit too big to be efficient...
Any idea's?

You can try AdRotator Control. It will display sequence of images with specified interval. Try this basic example[^]. This example[^] using database.

|
|
|
You may use JavaScript with timer to change the background color.

Hi - I'm implementing PayPal PDT (Payment Data Transfer) for payment confirmations in ASP.NET.
I'm going to receive a url post from PayPal with query string parameters. Then I need to send back the form at the bottom of the page.
I'd like to implement the form at the bottom as a non-visual HttpWebRequest. So far I have this code:
string urlPayPalEnvironment = "https://www.paypal.com/cgi-bin/webscr";
// Prepare web request.
HttpWebRequest request = WebRequest.Create(urlPayPalEnvironment) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
Can you help me extend this code to include the required hidden fields?
I've seen code on the web that builds a data string like this:
string postData =
"cmd=_notify-synch" +
"&tx=" + txId +
"&at=" + merchantIdentityToken;
Is this how HttpWebRequest works internally - hidden fields are simply converted into name-value pairs in a querystring?
Also - I'm not sure how the submit input would be added to this. It just has a value of "PDT" in the required form format below with no name. Any ideas on how to handle this?
Also - I've seen some examples where the HttpWebRequest just gets streamed out but I'd like an OO approach using the HttpWebResponse to get a handle to the response.
Thanks for your help!
<form method=post action="https://www.paypal.com/cgi-bin/webscr">
<input type="hidden" name="cmd" value="_notify-synch">
<input type="hidden" name="tx" value="TransactionID">
<input type="hidden" name="at" value="YourIdentityToken">
<input type="submit" value="PDT">
</form>

Hi..
I m working on an asp.net website. storing users in sql server db.
what could be the best way to know whether user logged in or not ? and restrict them to login again in another browser window or another machine.
Make sure I am not using authentication. I use to store logged in user to session.
Is it possible through application state.
thanks,

Application state would not be the best place for that, as the users session would not timeout until the application state timedout, the app pool was recycled or the app is recompiled (a change to the web.config would do this).
I would / have used Session State for this in the past, just set session state variable to true when the user is logged in and just check that when the page is loaded. something along the lines of;
Login Page;
<code>
protected void login_click(object sender, EventArgs e){
.... code to validate credentials ......
Session["LoggedIn"] = true;
Response.Redirect("defaultpage.aspx");
}
</code>
All Pages;
<code>
protected void Page_Init(object sender, EventArgs e){
if (!(bool)Session["LoggedIn"])
Response.Redirect("login.aspx");
}
</code>
If at first you don't succeed ... post it on The Code Project and Pray.

thanks,
I think this is all about authentication. you are redirecting the user to login.aspx if he is not logged in. that's fine.
I want to restrict one user to login in the second machine, if he is logged in , in one machine.
(simply dont want him to use application in two different browser window).
thanx

Oh, well in that case just store an ArrayList in Application State with all the logged in users in there (or a unique identifier for each user) then when a user tries to log in check if they are already in the ArrayList and show an error if they are.
protected void login_clicked(object sender, EventArgs e){
if (((ArrayList)Application["LoggedInUsers"]).Contains(txtUserName.text))
else{
ArrayList temp = Application["LoggedInUsers"];
temp.Add(txtUserName.Text);
Application["LoggedInUsers"] = temp;
}
}
Just dont forget to remove them when they logout or their session expires.

You said in last
"Just dont forget to remove them when they logout or their session expires."
will it work to remove entry in Session_End event in global.asx ?
thanks,

Yup, and if you have a logout page you would want to put it in there to.
But keep in mind that the session will stay alive for a bit after the user closes the browser, that period is configurable i just remember how.

Hi,
I've come across some articles that may have the solution to my problem, but I'm having a hard time implemeting the solutions, so I hope that anyone can help me out here...
The problem is, I have a page with a TabContainer (AjaxControlToolkit), I add each tab Dinamically on Page_Init (without checking either for PostBack or !PostBack), in each tab I also add a GridView.
So far so good, the GridView show the correct data, the problem is on SelectedIndexChanged, that never fires, I also have a RowDataBound event that fires on the creation of the gridView, but the SelectedIndexChanged doesn't, when the user changes the selection it goes straight to Page_Init.
I have the following code:
void Page_Init()
{
(...)
GridView gView = createGridView("gView_" + year.ToString());
tab.Controls.Add(gView);
(...)
}
private GridView createGridView(string ID)
{
GridView gv = new GridView();
gv.ID = ID;
CommandField cField = new CommandField();
cField.ButtonType = ButtonType.Link;
cField.ShowSelectButton = true;
cField.Visible = false;
gv.Columns.Add(cField);
gv.RowDataBound += new GridViewRowEventHandler(gv_RowDataBound);
gv.SelectedIndexChanged += new EventHandler(gv_SelectedIndexChanged);
return gv;
}
void gv_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
ViewState["index"] = e.NewSelectedIndex;
}
I was hoping to save the selectedIndex on ViewState, so I could 'catch' it after the Page PostBack in order to select the correct row (because the selected index is lost after the postback).
Hope I'm not asking a dumb question 
Thanks in advance

I'm not 100% positive, but i think it might have something to do with you generating your controls on page_init.
I'm pretty sure that page_init is called before your event handler so the controls are destroyed then recreated so the original control that actually caused the postback doesnt exist and therefor there is nothing to call your event handler.
Try adding your controls on PreRender.
Once again i'm not 100% sure, it's friday and i'm sick, but it's worth a shot.

Moved it to the Page_PreRender(), same issue 
The controls are created on each postback, but I neve trigger the selectedIndexChanged Event on the GridView, thus not being able to collected the selectedIndex. 
|
|
|
|
|
Once again this is pure suggestion, i havent had time to build a test but i dont *think* you want to recreate the controls on each postback. try, and just try, throwing a 'if (!PostBack)' around your code and see what happens.
I'm not exactly sure what the problem is, but i'm positive it has something to do with destroying and recreating the controls.
If at first you don't succeed ... post it on The Code Project and Pray.

Checking for PagePostPack, on building the page for the first time, the controls are created.
But when I change the selected index of a GridView the page is posted back and the controls are no longer 're-created'.
I am also on the same tought pattern :P Something to do with maintaining the state of the dinamically created controls.
I am messing around with the ViewState, but with no results so far.

Hi,
I have a .NET 2.0 web service written in C#. Within the C# code, I want to load a resource file and then get string value from it. I have been strugglling and googling this for a lone time, still no luck. Always get:
"System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "EDIResources.resources" was correctly embedded or linked into assembly "EDIWebService" at compile time, or that all the satellite assemblies required are loadable and fully signed."
Here is what I did:
1. created a resource file "EDIResources.resx" in 'App_GlobalResources' folder from VS 2008 solution exploer added some key/value pairs into it.
2. in C# class, I used below code to load the resource file:
ResourceManager resourceManager = new ResourceManager("Resources.EDIResources", Assembly.GetExecutingAssembly());
3. get string from resources:
resourceManager.GetString("E_0008");
but step 3 threw out the System.Resources.MissingManifestResourceException exception. I tried different suggestions for step 2: using file based resource manager, changing resource file name to start with my web services' namespace...none of them work!
Please help me out! Thanks a lot!

i dont have any experience actually using resource files, but one thing to check is that the resx file is marked as 'Embedded Resource'.
Check out this: Understanding Embedded Resources in Visual Studio .NET[^]

Hi All,
I have a string variable contain text that I would like to search for "Keyword" (AND, OR ) I like to do is search the string varaible strValue for the word "AND" that follow by word "OR" and insert "(" and the last word "OR" and insert ")" .The last "OR" might have "AND" or blank space, The combination could be any order I need to place the "(" and ")" where the "OR" exist.
For Example:
Orignal strValue = " col1 = "John" and col4 = "smith" and col3 = "John" or col7 <> "closed" or col9 > 1 and col5 = "passed" "
After the replace the strValue should be :
strValue = " col1 = "John" and col4 = "smith" and (col3 = "John" or col7 <> "closed" or col9 > 1 ) and col5 = "passed" "
The strValue then send to SQL store procedure as a where clause in sql statement.
Any assistance is greatly apprecaited. please provide codes example.
Thanks
DocHoliday.

It's probably not ideal to be dynamically generating WHERE clauses and passing the to your procedures. Could you post the Stored Proc code as there might be an easier way round this?

Hi,
I started writing a function to do the replace/insert but ran into issue when there are more then one "AND" then follow by "OR", the "(" get insert after the first "AND". Also when there blank space after the "OR" at the end of the string the function fail.
Thanks,
DocHoilday
Function codes:
Private Function ReplaceString(ByVal strValue As String) As String
Dim andIndex As Integer = strValue.IndexOf("AND")
Dim blankIndex As Integer = strValue.IndexOf("Blank")
Dim orIndex As Integer = strValue.IndexOf("OR")
Dim nextAndIndex As Integer = strValue.IndexOf("AND", andIndex + 3)
Dim secondBlankIndex As Integer = strValue.IndexOf("Blank", blankIndex + 5)
Dim temp As String = String.Empty
if orIndex > andIndex AndAlso orIndex < secondAndIndex Then
temp = strValue.Substring(0, andIndex + 3) + " ("
temp += strValue.Substring(andIndex + 3, secondAndIndex - andIndex - 3).Trim() + ") "
temp += strValue.Substring(secondAndIndex)
ElseIf orIndex > andIndex AndAlso orIndex < secondBlankIndex Then
temp = strValue.Substring(0, andIndex + 3) + " ("
temp += strValue.Substring(blankIndex + 5, secondBlankIndex - blankIndex - 5).Trim() + ") "
temp += strValue.Substring(secondBlankIndex)
End If
Return temp
End Function
