I want to open a website, change its javascript, then show the website + execute my changed js.
1) Is this possible?
2) How is this possible? ( VB.net, C#, FF + Addons )
EDIT: To your better understanding, I just want the js to be just changed for my browser output!
I used to write this:
Private Sub Example()
Static CachedPeople As List(Of MyApp.Person)
If CachedPeople Is Nothing Then
[code]....
But then wondered if I could reduce this to:
Private Sub Example()
Static CachedPeople As New List(Of MyApp.Person)
...rest of code...
End Sub
will the "New" bit only be executed once when the function is first executed but in the next call, it will already exist.
I have built a web browser and my new window function is working great, it allows me to open popups that use normal https links without a hassle. But I am having some problems when the links contain java code (like the one below:
("javascript:var%20x=window.open('https://auth.det.nsw.edu.au/pls/orasso/orasso.wwsso_app_admin.fapp_process_login?p_app_id=F0CB644DAE48EDE00D83EFE378FD435E','My_Staff_Email','menu=no,toolbar=no,resizable=yes,scrollbars=yes,status=yes')"
The reason why this operation fails because the string that is being passed to the Navigate method is not an actual URL.It is apiece of Javascript code which needs Javascript engine to process it firstly. Apparently, Webbrowser.Navigate() does not have this functionality,so it fails. If you simply put the string in IE�s address bar and press enter, IE will also not able to open it. The reason why it does work if you access the HTML page in IE and click the hype link is because this will make IE to use Javascript engine to process the code.
Since the API(Webbrowser.Navigate) does not have the functionality to process Javascript code,build up my own code to process the string which you get by using the GetAttribute method. The code reads the string and finds the actual URL and passes it to the Navigate method.
The only problem is that the javascript code constantly changes (varies upon what link is opening) and the url itself will change depending on what the link is linking to! Below is the code that I use at the moment to get the full link .finding the actual URL in the javascript even with the javascript differing from link to link).
Dim myElement As HtmlElement = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Document.ActiveElement
Dim address As String = myElement.GetAttribute("href")
I have JavaScript that works excellently but I need to change it to Update Panel and I can't get it to still work properly. What I want it to do is if it selects 1 in the first dropdown, pick c in the second dropdown. I am using asp.net vb.

I'm working on a web page that takes multiple PNG images and merges them into one image so the user can download the flat image. I would like to add a hue or color adjustment (like color balance in photoshop) so I can adjust the different PNG image layers without having to create a separate image for each hue. Right now I'm using ASP.net/VB.net and some jQuery and the System.Drawing.Image method to merge the images. I can't seem to find any information on doing this for the web without using silverlight or flash and I do not want to use either.

I am working on a little project and am having some issues with a checkbox. I am adding a number of checkboxes to an ASP table via code by adding rows and columns dynamically. This all works fine except for when I go to check them based on loading a preexisting record. For some reason some of the checkboxes are getting set to TRUE when the new row is added to the table. [Code]
View 1 RepliesI have several <asp:TextBox TextMode="MultiLine"> elements on a page. On load, I populate them (through the VB code behind), and then turn them into TinyMCE editors (through the Query TinyMCE plugin). Each text box also has a button associated with it, with the purpose of submitting the text back to the code behind for insertion into a database.I discovered earlier that when the submit button is clicked, I have to "save" the contents of the editor to the text box, but that is not my problem. Even after I've done so, the edits are not showing up in the code behind.As I've mentioned, I'm using jQuery. Here is my click handler. Keep in mind that all buttons are submit buttons in ASP.NET, hence the submit class:
$('input.submit').live('click', function() {
tinyMCE.EditorManager.triggerSave();
});

I want to be able to change an image depending on what is selected in the drop down box. I have this JS code to change the image. Simplified of course.
<script type="text/javascript">
function changeImage() {
var oDDL = document.all("ddlNAME");
var NAME= oDDL.options[oDDL.selectedIndex].text;
switch(NAME) {
[Code] .....
When I call this function I do it in my DDL implementation.
<asp:DropDownList ID="ddlNAME" runat="server" OnTextChanged="changeImage()" >
But for some reason the changeImage() is not firing. It is giving me an error saying
'changeImage' is not a member of 'ASP.default_aspx'
I've got a bunch if labels that are changed as a user inputs data into a form of mine. The Labels are changes with js on the client side. I then after all the submission are in put use a vb script to pull the string values from these labels. The problem is the vb net part is not reading the new values of these labels. Anyway I can get it to read the new values? I have over 40 labels.

I have two drop down. SelCurrentManuf and selCurrentModel. I want the option in selCurrentModel to change depending on the option selected in selCurrentManuf. How do i do it?
<asp:DropDownList runat="server" ID="selCurrentManuf"></asp:DropDownList>
<asp:DropDownList runat="server" ID="selCurrentModel"></asp:DropDownList>
This is how i am currently populating selCurrentModel
Public Sub PopulateCurrentModel()
Dim mySelectQuery As String = "SELECT * FROM Model where ManufID = "+ selCurrentManuf.Text+";"
Dim myConnection As New MySqlConnection(Session("localConn"))
[Code]...
but it only populates the first selected manuf, and doesnt change after
Private Sub selCurrentManuf_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles selCurrentManuf.SelectedIndexChanged
PopulateCurrentModel()
End Sub
I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

My problem is that some code I enter will not be executed. Here is an example of my Form Load event. If i debug the code then the first two lines are executed. The MsgBox won't be executed though. or anything else after it. My programm does run perfectly. But i cant make any changes anymore It's driving me nuts, I don't have the faintest Idea what could be wrong. I sent the code to a friend and he isn't having any problems at all. We both use win7 64bit (he has ultimate, i have home) [code]
View 2 RepliesI am developing a window application. I'm using Visual Studio 2005 and Mysql Database. The problem is, only one form is getting executed when I try to debug.I have changed the startup form to other forms(from a list of existing forms), but still that same old form is getting executed, even if I delete that form or exclude it from the project, it still keeps on executing.
Where this form is stored?(I deleted it from the folder where all other forms exist)
For intOuterCount = 1 to 5
For intInnerCount = 1 to 4

View 2 RepliesI have a hashtable of a class that contains a timer. When this timer elapses x amount of time, it calls a subroutine within the class. This subroutine calls several other functions and subroutines and then its done until the timer elapses again. Now one of the subroutines updates a label on the form and i can see that happening when its supposed to. There is another subroutine that should be updating another label but it is not. I believe this would be a simple correction but when i set a debug point on the routine it does not work. I'm not going to post the code for this as it is hundreds of lines of code and its probably just a configuration in the IDE that got changed somehow.
I run break points around the rest of the project just fine, even in other classes that use timers. Does anyone else have this problem of code being executed but not being able to debug it?

Assume I have an If-ElseIf decision to make. Do all ElseIf's get executed after one has been found true? [Code] Obviously that is not a real subroutine but I wrote that just to clarify what I'm asking. When this is run, on the second ElseIf the value is equal to 5 so whatever is inside that ElseIf would execute. Once that happens do the following ElseIf's get checked or does the program immediately go to the End If?

I want to add some action to my form when it is closed by clicking on the "X" button in the upper right corner of the form.How is this done? I suspect that i must add a handler for some event, but which event is it?
Currently i am using the closing event, but i dont get it to work properly.
I have a form that on load keeps closing without any errors... I have no clue what it wrong with it. How can I record all the lines of code being executed so that I can find out why it is closing. There are no errors or me.closes.
