I am trying to connect to an running instance of activex component in IE.I am using following piece of code. However, I am getting error 429 "Cant create activexobject"
Dim obj As Object
Set obj = GetObject(, "MyTimer.ctlTimer")
I got the following code from one of the other threads to check if a Folder already exists. But, when I paste it into my code, the ActiveXObject gets flagged with the message "Type ActiveXObject is not defined". How do I get around this?

I am using the activexobject in my project it works fine in IE. I know this is the microsoft control. I want to run the project in Mozila and Chrome but it showing the error as Activexobject is not defined.
View 1 RepliesI'm my program always fails at the same line:
objUser = GetObject("LDAP://CN=" & strUser & "," & ADPath)
If I reduce the code down to just this:
objUser = GetObject(), I still get this exception:
"Cannot create ActiveX component."
After googling this for about 18 hours, I found that it could be because of a permissions issue. I am a local administrator on the PC, so I believe that takes care of permissions. Secondly, I discovered that the dll file might not be registered. I tried to use the following command to register the dll file I think is being used:
regsvr32 "c:windowssystem32wldap32.dll"
It says the following:
Error - The module "C:windowssystem32wldap32.dll" was loaded but the entry-point DllUnregisterServer was not found. Make sure that "c:windowssystem32wldap32.dll" is a valid DLL or OCX file and then try again.So no matter what I try to do, I keep getting this unhandled exception error that says that it cannot create the activex component. What do I need to do to be able to use this getObject() command? Is the problem with LDAP? What activeX or DLL file is failing if even just running the getObject command gives an exception?
Trying to run this piece of code and i get the error cannot create activex component.works fine on windows 2003,works fine on windows 2008 if user is logged in with admin access.

At the moment i'm creating a remote object instance by:

I am creating a class ("Class B") which is used by another class ("Class A") which instantiates it in VB.NET 3.5.I would like Class B to read a value assigned to one of its properties by Class A every time an event happens in Class B.However, I would like this property value to be dynamically assigned to the property by Class A when the event is fired in Class B.I was thinking about somehow creating a delegate function in Class A that is linked to the property in Class B so that when the event is fired in Class B it would eventually invoke the delegate in Class A so that it returns a value to Class B.I've been reading around delegates (that's how I arrived at the idea), but I am stuck on how to code this up - could someone please help with some skeleton code?

I've been trying to get the UNC path for a mapped drive in a web application written in VB.net 2005. I was able to get this code working[code]...
I tested this code out in a test application - just a simple web page. But when I plug the code into my actual project, it doesn't work. In my testing of other examples, I figured out that WNetGetConnection returns a system error of 487 - ERROR_INVALID_ADDRESS. But I don't understand why it would work in my test application but not my actual project application.
In our code base there is a function which should return either an object or nothing. The exact code is this : Return NothingThe calling method looks something like thismyObj = theClass.function()if myObj <> nothing then // fails

Ok, here is the problem,in vbscript, i was reading parts of streams
i.e.
teststrid = left (strLine,8)
teststrnm =rtrim( mid (strLine,15,30))
teststrx = mid (strLine,57,8)
teststr = left (strLine,3)
strFormcode = left (strLine, 10)
strSymmetrycode = left (strLine,14)
strSigncode = left (strLine, 10)
Even in cases that strLine length was less than the index used to split the string, the program kept running.Now i am trying to do the same in VB.net, but since the strLine is not always bigger than the index used to break the string, it ives an error.I do not want to use try catch, because i will have very dirty and uselless code.
I was thinking something like resume next, but i guess it doesnt exist anymore.

I have a page in which one chooses from a selection of dynamically generated buttons. The ASPX code is as follows:
<div>
<asp:Repeater ID="rptrHalls" runat="server" OnItemCommand="Choose_Hall">
<ItemTemplate>
<asp:Button ID="btnChooseHall" runat="server"
[code]....
When I first tried running the code I received an error message of "Invalid postback/callback argument". I set the ASPX page to have a enableEventValidation="false" property and tried running it again. It generates the page fine but when I click on a dynamically generated button it acts as if it is loading something and then just brings me back to select_hall.aspx (the page all this code is one), when (as you can see above) it should take me to select_room.aspx.

View 6 RepliesI'm trying to update an Access database by using an OLE connection, retrieving the information from textboxes where the user enters the new information.All the fields in my Access table are required fields, so I have validated that some info is entered in each one of the textboxes and that is the correct data type.But when I run the update query I get an error message saying something like values haven't been entered for some required parameters (my Visual Studio is the Spanish version, so I can't give the exact error message in English).The bit of code where the error occurs is inside the procedure called by my "Ok" button:
Dim campo1, campo2, campo3, campo4, campo5 As String
Dim campo6, campo7, campo8 As Double
Dim campo9, campo10 As Integer
[code]....
(I didn't post the whole code inside the procedure, but of course I'm creating the connection and everything)
The table has 10 fields, and the data is read from the textboxes and stored in variables (campo1, campo2, campo3, etc.), which I'm then using in the "set" query command.
"id" is the first field from the selected row in the datagrid, which I'm sending as a parameter to the procedure called by the "OK" button.The error message shows at runtime, so I'm guessing it's something in the query. Am I writing it correctly?
I need to open a *.py file in the shell (DOS) box, but it returns an error that no file was found at the specified path. But this path is completely correct. Unless Visual Basic are referencing to paths in another matter than C#? 'Cause I am developing in C# and referenced to VB to do this.
