View 1 RepliesI have a client who wants to read a text file and then output the contents word by word in a slideshow.
View 7 RepliesI would like to read all content that's been written to the output stream. I'm attempting to do this using an HTTP module, and it seems like the obvious timing would be when handling the PreSendRequestContent event.
However, if the output stream seems to be set to write-only, as I can't read using a StreamReader. Is there a way I read and re-write the content without writing my own IIS module?
How to handle input/output streams to read some data sent from mobile phone app and send it back via ASP page?
The thing is, I've managed to do this with Java servlets, but now I need to do the same thing in ASP.
I'm trying to export data from an asp.net page to an Excel file and I'm basically just outputting HTML to the XLS file and let Excel interprets it, by using this type of coding:
[Code]....
Although this is doing fine for exporting raw text, I now have to export to the same Excel file an image. However, the same kind of method I'm using right now only seems to insert a "linked" image, I mean, the image appears in the file, however, the user viewing the file has to be online since it's a direct link to the file in the server. I would like to able to "embeded" the image in the file, just like how it's made when you insert manually an image using Excel.
However, after some online research I can't seem to find any solution for this.
I can't use Microsoft.Office.Interop.Excel library, and a third party software isn't advisable also, that's what made me try out the HTML output solution, which worked ok for the text. But now, for inserting an image, what can I do? Is it possible to achieve what I pretend?
I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)

Is there any way to know the webmethod that raised the error?
I want execute below callback() method after completion of document.getElementById('btnDownload').click(); method . Now callback()executing immediatly. I want wait "Click()" process done then Execute callback(); method.
function LoadPopup() {
// find the popup behavior
this._popup = $find('mdlPopup');
// show the popup
this._popup.show();
// synchronously run the server side validation ...
document.getElementById('btnDownload').click();
callback();
}
function callback() {
this._popup = $find('mdlPopup');
// hide the popup
this._popup.hide();
alert("hi");
}
When this function is hit , it does not call my function in code behind? Why could it be doing this? How can I fix this error.
$(document).ready(function() {
$('[id$=btn_Update]').click(function() {
var reten = $('[id$=txt_Reten]').val();
var i=0;
var selectValues = "";
var ProdID = new Array();
$("#lst_ProdId option").each(function() {
selectValues = selectValues + $(this).text() + ",";
ProdID[i] = $(this).text();
i++;
});
for(var j=0; j < ProdID.length;j++)
{
// alert(ProdID[j]);
}
var params = "{'ProdID':'" + ProdID + "','RetenP':'" + reten + "'}";
$.ajax({
type: "POST",
url: "/ProductPricing/Products/RetenPeriod.aspx/UpdateRetenPeriod",
data: params,
contentType: "application/json; charset=utf-8",
datatype: "json",
success: function(result) {
alert("sucess");
},
error:function(e) {
alert(e.statusText);
// if(errorThrown != null)
// alert(textStatus+ ":"+errorThrown);
// else
// alert("fail");
}
});
return false;
});
return false;
});
This is my webmethod in code behind:
[WebMethod]
public static bool UpdateRetenPeriod(string[] ProdID,string RetenP)
{
for (int i = 0; i < ProdID.Length; i++)
{
update(ProdID[i],RetenP);
}
return true;
}
I have a web method in my code behind:
[System.Web.Services.WebMethod]
public static string GetStateData(string state)
{
//this is where i want to call a javascript method "GetItems"
}
I have a javascript method that retrieves some values for me and I want to get use one of those values in my web method
function GetItems() {
var variable1= $("#<%=Item1.ClientID %> input:checked");
var variable2= $("#<%=Item2.ClientID %>").val();
return [variable1.text(), variable2.val(), variable2];}
I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.
I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there
var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?
I need my page to work when JavaScript has been disabled. But my button is outputting onclick="WebForm_DoPostBackWithOptions...". When I set CauseValidation="false" it disappears but I need validation. In what circumstances is WebForm_DoPostBackWithOptions outputted?
View 1 Replies I am having trouble finding any information on this but basically in MVC how do I set up a controller method do read a GET request? For example I have the following url,

I am developing a site which includes several different javascript files and libraries. For optimization purposes I have implemented YUI Compressor for .Net
This will minimize and combine my javascript files into one single file.
Now I have put this up in a MSBuild script that automatically does the compression and minimization and outputs it to a file of my choosing. However, I still wish to keep the original javascript files in my development environment. My question is simply:
Is there a good way to depending on the Debug setting for example choose which javascript to use? This to not have to change the MasterPage by hand each time I release the build.
Allow me to illustrate.
If I am running in Debug="true" I wish my MasterPage to include the following javascripts:
<script type="text/javascript" src="first.js"></script>
<script type="text/javascript" src="second.js"></script>
<script type="text/javascript" src="third.js"></script>
<script type="text/javascript" src="fourth.js"></script>
If I am running in Debug="false" I wish this to be outputted in the MasterPage:
<script type="text/javascript" src="compressedAndMinimized.js"></script>
I would like to display an output on an external website by including a javascript on that external website.
On my aspx-site i did:

I only get a white page on my external site :(
Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.
Is there some way to intercept the HTML output stream in asp.net and make modifications? Eg using httpmodules or something? I know this is possible using java servlets and assume there must be an elegant way to do this with asp.net.
My purpose is to combine the many javascript files into one composite script which has been minified/packed, to make the page load faster.Eg, if my page normally outputs the following in the page head:
<script type="text/javascript" src="/scripts/blah.js"></script>
<script type="text/javascript" src="/scripts/yada.js"></script>
I want to replace that with the following:
<script type="text/javascript" src="/scripts/all.js"></script>
(also i realise i'll have to create all.js somehow).
I have a ListView (in an UpdatePanel) connected to a LinqDataSource. When the page loads and/or I navigate through Postback, the code snippet (below) will display the following output:
[email.gif] someone@adomain.com [email.gif] www.adomain.com
However, when I use a few DropDownLists (also in the UpdatePanel) to filter the results (reset the DataSource to a Linq query and call DataBind), the same Contact is displayed like this:
[email.gif] [email.gif] www.adomain.com
[Code]....
If the parameter is a URL, the FormatEContact method will return:

So, after spending some quality time with Bing and Google, I've learned that the above js code is treated as just text and not evaluated. Therefore, the most often recommended solution is to eval() it. Unfortunately, I can't figure out exactly how, when or where to call eval().
i am trying to read file from a stream.
and i am using stream.read method to read the bytes. So the code goes like below
FileByteStream.Read(buffer, 0, outputMessage.FileByteStream.Length)
Now the above gives me error because the last parameter "outputMessage.FileByteStream.Length" returns a long type value but the method expects an integer type.

I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
Here's how I return a single function result. How do I return multiple output values?

First off, suggest better ways if you want rather than patch up this code. I am just starting this project and it is first time I have tried to code a web site so anything you suggest is very much welcomed. I have spent the last 2 and 1/2 days trying to find workable answers to this but none I have found and tried seem to fit. If needed I can email screens shots or code. I am trying to construct a website that will have the same main theme throughout as far as the header, navbars sitemap, and footer go. Naturally the content will vary from page to page. I want to use a single master page and css stylesheet for this main theme and I will change the content format as needed per page because each page may vary somewhat.
However, about 15 of the pages will all use the same format for their content and this format will differ from the rest of the site but the format of the main theme will stay the same. So I am trying to create a nested master page to use to format the just the content area for all these pages while retaining the main theme for the header, etc.. I believe I should use a separate css file with the nested master page to handle the formatting of the content areas for these 15 pages. I have code that looks like it works when viewed in web developer but design view but does not work when viewd through a browser (IE, Chrome, Firefox). So far I have the following done in web developer.
If it helps the code and screen shots follow. Master Page called "Parent.master". For all theme throughout site Nested Master Page called "Lab.master". For the 15 like pages Primary stylesheet file for main theme called "StylesheetNew.css" For site theme Secondary stylesheet file to syle the 15 like formatted pages. It is called Labmaster.css Labs.apsx file to use as first of the 15 like pages.
Finally screens shots from web developer and browser. Sorry try as I might I could not capture screenshots and put them into this post. The problem is that web developer shows all the area (many lines high) with gray background and with the XXX text that I want to allocate for content in the 15 pages. Yet all the browser show is one line of text o a white background followed by the footer. It looks like the LabStyleSheet works in Web Developer but not in a browser.
