Javascript - __doPostBack Not Working In Safari Or Firefox, Works In IE
Jun 19, 2012
in my asp.net application, two buttons call a javascript function called refreshView, below is the function refreshView.
function RefreshView() {
__doPostBack('ButtonApply', '')
window.parent.location.href = "dashboardtree.aspx"
}
In IE, this is working correctly, but in firefox and safari the page refreshes (due to the window.parent.location) - but never calls the doPostBack (i was able to tell this using tracepoint and the sub that is called stores values to the database, the values are not being stored as well, sub is never hit). Below is the first line of the sub.
Private Sub ButtonApply_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonApply.Click
Can anyone see why this would not work? I figured I could always replace the doPostBack with pageMethods and create a new sub/function - but I'd like to complete this the way it currently is.

I have this function correctly linked in an external .js file...
function SubmitAge(age, UpdatePanelID, HiddenAgeID) {
$get(HiddenAgeID).value = age;
__doPostBack(UpdatePanelID);
}
and am calling it like this from an onClick of an a href="#" ... html tag (tags removed, please scroll right as stackoverflow has the greatest difficulty in displaying simple content, 7th display related edit, thanks stackoverflow)
a href="#" onclick="SubmitAge(24, 'ctl00_MainContent_arFrom_upAgeRange', 'MainContent_arFrom_HiddenAge')" runat="server" 24 /a
yet, i am getting this error, and its being called on the first line of the SubmitAge function (line with $get(HiddenAgeID)... etc...)
Error:Microsoft JScript runtime error: 'null' is null or not an object
i've copied and pasted my WATCH windows in visual studio .net (vs2010 beta 2 using vb.net & c#) while the execution breaks inside teh SubmitAge .js function...
age 53 Number
UpdatePanelID "ctl00_MainContent_arTo_upAgeRange" String
HiddenAgeID Undefined identifier Error
Why on earth is HiddenAgeId, clearly passed just like UpdatePanelID, is returning an "Undefined identifier Error"???
edit: Update: turns out it works perfectly (as it should) when i load it up in FireFox, but has the resulting error in Internet Explorer, this is not a browser compatibility issue, it should also work in IE, but it doesn't!

Here's the situation: I have a variable number of dynamically created update panels on my page, so I thought I would write one method which handles all of the loading for each one.
My Updatepanel creation looks something like this:
Dim newUpdp As New UpdatePanel
newUpdatep.ChildrenAsTriggers = False
[code].....

I have a .NET login page. It works properly in Internet Explorer 7, but i want to make it compatible with Chrome, Mozilla and Safari.
The login code behind is:
Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click
{..................
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "test", "login()", True)
........}
The ASPX page code is:
function login()
{
if(document.getElementById("ctl00_Sidebar_Contentplaceholder_Lo1_SaveFlag").value =="Y")
[code]....
This is not working. I tried to debug it, but in debug mode the cursor only steps through the code behind. I'm not able to enter the javascript login() function on the aspx page.

I am trying to allow the user to download an excel file, by using
Response.Redirect(
"http://localhost/myapp/download_folder/example excel file_july.xls")
in page load of an ASP.net page but on the client side i a m getting the following screen in firefox 3.5 You can observe that the file name and file type are shown as empty fields. The ok and cancel buttons are not doing anything.This happens only in firefox 3.5, it is working in firefox later versions and other browsers.I tried clearing the Response with Response.Clear(), using Response.BinaryWrite with the file byte array and even tried to open the file with the javascript by calling window.open(url).

I am having issues with my program. It should update every time i click the button, but it runs through perfectly on the first click, after the first click it does nothing.This is a UDP Program, where the client sends a packet with a sequence number and payload which are separate items in the packet. The server receives the packet, reads the sequence number, and then sends back the next sequence number the client should send.The client then receives that from the server with the same payload.. And then should change its sequence number to the one it recieved, and send that to the server..The client works up to where the client updates to the sequence number it receives from the server.. But both show no effect on any clicks after.
Heres my Client

I have VB.Net application that has worked fine for years on XP and Windows 7. For some reason the last update I put out does not run even the simplest VB commands.Simple Environ() fails.I have tried putting simple VB commands onto a MsgBox on the start of the app and everything raises an error. I have no idea what is going on! The exact same app runs fine on Windows 7 clients. All the XP machines including a fresh XP virtual machine with the .Net 3.5 framework even gives the errors. No VB commands are working. I thought maybe something happened to my vbproj files, so I copied an older one from a couple weeks ago when things worked fine and it still does not work.

I am converting old VB6 code to VB.NET with ADO.NET (OleDB). This is my query that will create a blank table when ran in VB.NET, but then works when ran directly in Access. This code presumably also works in VB6, as I am using the same SQL:
SELECT qryAsOf.name, qryAsOf.type, 0 as opt, 0 as swap
INTO qryCon
FROM qryAsOf
LEFT JOIN qryLinked on qryAsOf.c = qryLinked.lc
I feel like this has something to do with the left join and select into being together, but like I said it is only VB that has an issue with it, Access handles it perfectly.Without the INTO line, this query returns all 600+ rows.
This DOES NOT WORK:
cm.CommandText = "CREATE TABLE qryCon (etc...)"
cm.ExecuteNonQuery()
cm.CommandText = "INSERT INTO qryCon SELECT ..." '(rest of query above without INTO line)
cm.ExecuteNonQuery
This DOES WORK:
cm.CommandText = "CREATE PROC qryCon AS SELECT ..." '(same select as above without INTO, again)
cm.ExecuteNonQuery
The CREATE PROC that does work is fine, except I need to insert data into it later, so I get errors about how I need an updatable table. I really want the end qryCon to be a table, but I can't seem to get that to work :(
*However, when I do something like this (using the stored proc (renamed) above which, if viewed in Access, is full of data)
cm.CommandText = "SELECT * FROM storedProc"
dr = cm.ExecuteReader
[code]....
This DOES NOT WORK! By the way, I removed the concatenation in the query for readability. It is correct in the actual project.

I am not stuck with the code side but rather what seems an issue when using VB and creating well verifying an Twitter Account. I have tried to explain as best as possible but please ask if you need more info
I am currently well on the way to finishing my Twitter Account Creator which also verifies and completes the profile fields but I have encountered a problem and for once not a problem relating to the code side of things at least I don't think it is.
At the moment for testing reasons I have 2 buttons one which creates the account and a second which verifies the account now I am using incognitomail.com (temp email provider) and have 2 web browsers running within my VB program. 1 is for Twitter and 1 is for Incognitomail.com I have no problems clicking and navigating to the verify link and then logging in to verify the Twitter Account but it never verifies and I cannot figure out why.
Say I put another text box and used it to navigate to url's on web browser 1 (twitter) and copied the verify link and put it in the text box it navigates I login and its the fine the account is verified but if I set VB to navigate (can't click because it opens in IE and not within the VB web browser) to the verify link it never verifies I have even tried making the text box fill and then navigate via that just as if a human was doing it but still no luck.
Does anyone have any idea as to why these Twitter Accounts are not verifying when the VB program performs the navigating to the verify link then login but if I do it myself i.e copy the verify link put it in the text box which navigates the web browser then it verifies fine?This is the one step standing in the way from my program being about to create and verify accounts and will not cost a fortune as this was a personal project to counter the lack of Twitter Creators which both work fully and are cheap.

The issue at hand is this. I want VB.Net code to be able to talk with Javascript code, specifically, passing variable values back and forth.A web page contains several DIV elements that actually can open and close kinda like a dropdownlist in it's functionality (there are 8 of these). Initially, when the page loads, these DIV's are closed. However, when a user opens a DIV or multiple DIV's, their are various textbox controls they can make changes to. When any changes are made, they click the submit button to save the changes. Then, when the page reloads, I want the program to remember which DIVs were open so after the page finishes loading, those DIVs that had changes made to them will be opened instead of closed. What would be the best way to handle this. Should it be done all in the code-behind file or javascript alone or both?

I have the following code which I want to run when the page first loads and then again when an update panel (asp.net) is run. Therefore I need to use function pageLoad() rather than document.ready.
function pageLoad() {
$(".zoomImage").each( function() {
$("<img src='"+$(this).attr("src").replace("-thumb.jpg",".jpg")+"' />").appendTo(".howitworksText > div");
});
};
Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

Not sure why this isn't working. There is no js error, but it just doesn't set the display property to "block". If I remove the inner most if statement, the display property for the div control is changed when the last radio button is selected from the group.

Im trying to get a connection between a JavaScript WebSocket and a TCP Server/Client applicat written in VisualBasic .Net . My problem is that the handshake fails. I do get a handshake request from the local website, but it does not accept my response.
The code of the JavaScript file:
<script type="text/javascript">
var ws;
function connect() {
[Code]....
I now get the correct Sec-WebSocket-Accept String (dXOwyU6vuIMy61iK64Xi0VrmyOQ=), anyway the WebSocket seems not to handle the handshake response. I tried debugging it with the Chrome Developer Tools, but I don't get usefull information from it.

I am using Virtual Basic with ASP.NET in Visual Studio 2008. I am using Webmethod to communicate from/to the server with the client. Data can be queried and returned in small amount, but when I try get a relatively large amount of data, it's returning me a Server 500 error. My data is 226561 character long, so it's not that large, but it's relatively larger than my other working testing set, which are about 10k character long.
JavaScript:
PageMethods.my_func("context", success);
function success(result, userContext, methodName) {
[code]....
Is there anything I can change to increase WebMethod returned string length limit? Is there even a length limit or is it some other problem I could not see?

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.
