Asp.net - Microsoft JScript Runtime Error: 'document.getElementById(...)' Is Null Or Not An Object
Aug 17, 2011
I am getting this error when I call a javascript function to display a modal window:
Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object
The code block is:
else if (action=="officeview") {
document.getElementById("OfficeContent").src="ChangeView.aspx";
ShowFeatureModal('AppView','OfficeContent')
The object is this situation, does exist. Error is caused at: document.getElementById line.What else could be causing the error?
Update:Index.aspx is calling the javascript function which is located in sysUtilities.js file. The source file is yet a seperate page (ChangeView.aspx)

Am I approaching this in the correct manner? Any other suggestions to ensure my datepicker remains usable within the update panel?Thinking this may be due to the fact that I have the controls nested within an update panel... several of them in fact.
stuck on this one basically, im trying to navigate from one page to another iv looked though the HTML code found the input_id and .invokemember("Click")
the line of code i used was WebBrowser1.Document.GetElementById("ctl00_ContentPlaceHolder1_btnNext").InvokeMember("click")
I have a working code that works if the element id exists, but what happens when it doesn't. It stops the code read from where it doesn't exist. I don't receieve any errors,. I have tried:
If WebBrowser1.Document.GetElementById("displayAge") = "" Then <---this doesn't work, needs to check if Element exists if not then exits, if does then it gets attribute
If I am using with WebBrowser how I can add tags to source code of the page in runtime (Make a changes on site). For example: I have site with this <html><head> Test page </head><body> this is the text </body></html> Now how possible to add elements/tags to text in runtime?

For that i added a webbrowser to the project, and pointed it to navigate to my localhost server where i have some pages.

MVC 3. VB.NET I have the following controller action in my application to send generated PDF files to the User by download. The function works fine when the controller itself has been invoked. But when I call to the function from outside the controller it returns a " Object reference not set to an instance of an object " error as soon as it hits the response.contenttype line. I have verified that all of the variables are in fact making it to the below action.[code]any ideas why this is only working when called explicitly from inside its containing controller???
I created a report using report document object model in visual studio 2008 with vb.net. But I found one error. When the user clicks export button in client side, the following error will show. But the first time is OK before the user clicks export button.

Imports System.Data Public Class Form1 Dim Ping As Net.NetworkInformation.Ping
Private Sub Request_Stuff_button_Click() Call Main.createObjects Call My_Control.requestStuff End Sub
at the 'Call My_Control.requestStuff' line.The 'Main' module looks like this:Public My_Control As ControlObject
[Code]...
right before the line that gets me the error, x gets the correct value right before the error happens which means My_Control is definitely an object and is definitely not nothing.
I am having an issue with a data filled combo box. I can not put my finger on why it is giving me the "run-time error 424 object required" error. The code is simple and the data is there.
Dim sSql As String Set rsMfg = New ADODB.Recordset sSql = "Select SourceID, [Source Name Code] AS sc From Source Order By [Source Name Code]" Set rsMfg = New ADODB.Recordset
I am using the ModalPopupExtender control to display a modal popup dialog when a button is click. The problem is that dragging the dialog results in an 'scrollleft is null or not an object' error. Here's a video demo and here is ALL the code: If possible, I'd like to resolve this problem w/o resorting to modifying the AjaxToolkit scripts themselves.
I get the error (Run-time error '429' ActiveX component can't create object) when I execute my VB 6.0 program on Windows server 2003 BUT not on Windows XP Professional.The code that causes error is: Set wrkJet = CreateWorkspace("", "admin", "", dbUseJet)
My dot net windows application (visual studio 2008, vb.net) is running fine on 32 bit windows XP. But in 64 bit windows 7 it is throwing the following error when trying to open frorms which have a reference to GCombo.dll."Run-time error '429': ActiveX component can't create object"The application was originally on vb6. It was converted into vb.net. I build the application in x86 mode. I have registered the dll manually. But nothing worked.
I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu If menuData.Children IsNot Nothing Then menuData.Children.AddRange(GetChildren(menuData)) End If Next
If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:
Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))
For Each menuData As MenuData In builtMenu menuData.Children.AddRange(GetChildren(menuData)) Next
Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))
Our VB.NET application has a .NET dll, with a registered TLB file; so that VBA in Microsoft Word and Microsoft Excel can call into the application. The application functions correctly except when it is called into via MSO on Vista. This functions correctly on Windows XP machines but on Windows Vista and Windows 7 machines it is returning a 429 error. A reference to the TLB file can be assigned in the VBA References dialog box, on Vista.It doesn't appear to be a problem in our application as a simple Test libary does the same thing. Microsoft Applications have been 'Run As' Adminstrator, and Vista UAC is turned off, but I am thinking there is perhaps a security issue?
But I get a runtime error that Operator '=' is not defined for types 'Object' and '1-dimensional array of DataRow' There should be an easy way to do this that doesn't involve creating new tables, etc.
I am getting an error when i try to populate some combo boxes with a value, the combo box has values in and the right amount the code is getting the right number.

I have been trying to use vb2008 to automatically update CustomDocumentProperties fields that I have set up within a pro-forma document. I can load the Word application and word document without problems.I want to update the CustomDocumentProperties fields with data read from a dB. To do this I am assuming that I need to iterate through the CustomDocumentProperties fields within the word document and when one is "found" that matches the data I wish to merge then assign the dB value to the field.The problem is that I am getting an exception error when I try to reference the document customdocumentproperties
"Error : Unable to cast the COM object of type 'System._ComObject' to interface type 'Microsoft.Office.Interop.Word.CustomProperties'. ...... "
my code looks like;
Dim WordApp As Word._Application Dim odoc As Word._Document Dim BContinue As Boolean = True
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'. ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then IndexOutOfRangeException was unhandled Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
I have an error ERROR [22018] [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. and I've been trying to solve this but unfortunately I couldn't get the hack of this error. I'm a newbie in dotNet.
