Hi guys,
PLZ help me!
Scenario - My client has 2 server machine. one is database server with oracle 10g database 64-bit. Another server(new one) is windows 2008 server which has an .net 2.0+3.5 website hosted. This website make use of System.data.oracleClient dll . Problem is that this app is not able to connect to oracle 10g database server though it is able to connect to some other 11g R2 database server. On this app server we have also tried to install oracle 10g 32-bit client but still can't access. Tnsping and sqlplus is working fine. Pls. suggest.
Solution that we tried :-
- Gave permission and added various users to oracle directory and sub-directory like IIS_Iuser,network service, anonymous etc.
Possible culprit:-
- Earlier on this app server oracle 11g 32-bit client was installed. So my client has although worked on to remove it by manually deleting folder , deleting registeries , extra home directories. but it looks like a possible reason to me..
Note - we use some internal ddl for dataaccess , so im not able to see actual error just some OLEDB exception.
Pls help

I have 4 projects: GUI (Web), BLL (C#), DAL (C#) and POCO (C#) and I want to implement a custom membership provider. Here is what I did so far:
1) Created MyMembershipProvider class in DAL that implements MembershipProvider
2) Created the database and the edmx in DAL
Next I think I should implement the User repository, Is it in DAL or BLL ?? And I have a problem passing the connection string from App.config in DAL project to the one on BLL project or Web.config in GUI project. I'm confused, please help

I am loading dynamic questions in the panel part of aspx page, in the Page_Init method, to avoid situation of losing the values on postback issues. There is a linq statement that loads this dynamic panel.
The same aspx page is used in 3 step registration process, by hiding and showing panels.
This dynamic questionnaire is step 3 of process. I now need to limit the questions that appear on this dynamic queationnaire, by what was entered in step 1 of questionnaire, like a radiobutton choice. How can I pass this to the Page_Init page? Or can i reload this dynamic question which is loaded in page_init, and limit the questions?
Thanks!!

Whenever you are posting back you can access Request.Form["ElementName"] to get what was the value before the form got posted. I did not understand the purpose of "linq statement that loads this dynamic panel". Can you tell me what is the architecture you are using. Is it Asp .Net Forms or MVC?

Your GetData method does not contain a variable or parameter called name, and your _Default class does not contain an accessible field or property called name. Therefore, the compiler doesn't know what you mean by "name", and cannot compile your code.
Assuming you want to pass the name you're looking for to the method, you need to introduce a parameter:
public static List<Data> GetData(string name)
{
...
}

Thank you so much for your response. I really appreciate your help.
I manage to solve the compile error but my application now output blank webpage on the client-side. I can not seem to figure out why, but would I have to invoke callback method on the asp.button?
I am trying to build an application which can filter test data and display visual charts using google charts API.

Since you're using a master page, the client ID of Button1 won't be "Button1"; it will be something similar to "ctl00$MainContent$Button1".
If you're using ASP.NET 4.0, you can set the button's ClientIDMode[^] to Static, which will make sure that the client ID matches the server ID. If you're using an earlier version of ASP.NET, you'll need to find the correct ID, or use a different selector to find the button.
<asp:Button ID="Button1" runat="server" Text="Search" ClientIDMode="Static" />
You'll need to do the same for the SearchText textbox, since you reference it by ID:
<asp:TextBox ID="SearchText" runat="server" ClientIDMode="Static" />
miss786 wrote: $('#Button1').click(function () {
$.ajax({
...
});
})
You need to end the event handler function with return false;, otherwise the button will cause a post-back and the AJAX call won't run. You should also terminate the statement with a semi-colon.
$("#Button1").click(function(){
$.ajax({
...
});
return false;
});
miss786 wrote: data: "{name:'" + $("#SearchText").val() + "'}",
I'd strongly recommend using the built-in JSON.stringify[^] method to convert the parameters to a string. If you need to support IE7, you can use Douglas Crockford's JSON-js[^] script.
data: JSON.stringify({ name: $("#SearchText").val() }),

You've added a runat="server" to <div id="visualization" ...>. As a result, the client ID will not be "visualization"; it will be "ctl00$MainContent$visualization". As a result, you'll get a "container not defined" error from the Google script.
Either remove the runat="server", or add ClientIDMode="Static".
<div id="visualization" style="width: 600px; height: 400px;" runat="server" ClientIDMode="Static"></div>

hello Richard.
Thank you once again for your quick response. The code still does not work without the runat or with the clientIDMode tag. I also tired debugging the javascript but I am still unable to pin point where the code is falling.
Any advice would be most welcome.
Thank you so much.

The code works fine for me in Firefox 25, Chrome and IE10.

Hi,
Are you able to see the charts when submitting the search input? Would you mind me asking, what Visual studio you are using? I shall keep trying on my end.
Thank you so much for your help.
Kind regards
|
|
|
|
|
I'm using .NET 4.5.1 and a text editor. As long as you're using .NET 4.0 or higher, it shouldn't make any difference.
Are you seeing an empty chart? The String.Contains method[^] is case-sensitive, so if you type "clavs" you'll get no data back. If you want a case-insensitive search, try using the IndexOf method[^]:
[WebMethod]
public static List<Data> GetData(string name)
{
var dataList = new List<Data>();
...
return dataList.FindAll(r => r.ColumnName.IndexOf(name, StringComparison.CurrentCultureIgnoreCase) != -1);
}

Hi richard,
I really appreciate your support and time into this but for some strange reason, I am still seeing an empty chart whenever I trigger the search function on the client-side.
I changed the search code line from string to index function as you suggested, however still no result. I do not mind it being case sensitive or not. Whenever I type in "CLAVS 2007-1 M2A" into the search textbox, I am still getting a blank page.
Many Thanks

Strange - the code works fine for me. The only difference I can see is the base class for your Data class. Try removing it in case there's something odd with the serialization.
public class Data
{
public string ColumnName;
public double Value;
public string Date;
public Data(string name, double price, string date)
{
ColumnName = name;
Value = price;
Date = date;
}
}

Hello Richard.
Sadly, I am still unable to get the charts to display using the search criteria. 
I also noticed, my data.cs file is under App_code, could this be issuing the blank charts on the client-side.
I really appreciate your help and time.
Thanks a million.

I doubt having the file under App_Code would make any difference.
Here's the entire file I'm using to test. I have a different master page, a different file name, and I'm not using a code-behind, but otherwise everything should be the same:

MasterPageFile="~/_controls/Site.master"
Title="Chart Test"
%>
<%@ Import Namespace="System.Web.Services" %>
<script runat="server">

Dear Richard,
Apology for the late response. I am writing to sincerely thank you for helping me on this small task. I really appreciate your support and time into this post. After long struggle, I manage to find the cause of problem which was syntax errors in the #button.click javascript code.
$(document).ready(function () {
$('#Button2').click(function () {
$.ajax({
type: 'POST',
dataType: 'json',
contentType: 'application/json',
url: 'Default.aspx/GetData',
data: "{name:'" + $("#SearchText").val() + "'}",
success:
function (response) {
drawVisualization(response.d);
}
});
return false;
});
});
Thanks a million for help. Have a great day.
Kind regards

Hey all,
I have got a problem with my buttons on my website, the buttons not always causing a postback, sometimes it works and sometime it does not, the buttons CausesValidation are set to false. I am not getting any javascript or server side errors.
Any Idea that will cause this issue?
modified 4-Nov-13 11:04am.
|
|
|
|
|
If you have CausesValidation set to True and you are not getting a postback, then it's possible that your validation controls are firing and not being displayed.
If you have validation controls set up make sure they are displayed properly to a ValidationSummary control. You could also set your CausesValidation property to False to by pass the validation and make sure it's hitting the server.
|
|
|
|
|
hey,
sorry, I meant to say my CauseValidation is set to false, I have take a look and there is no validation on that page.
|
|
|
|
|
Posting your code would help. Have you walked through it to make sure the code is following the proper path?
|

Hey Joshua,
I have solved the issue, it was my ComponentArt menu on my master page, I have read that it's a common issue with ComponentArt 2007 and framework 3.5, I decided to scrap the component and create my menu from scratch.
Thanks for your help
