I get the error "35750 unable to open internet handle" from a server running a Visual Basic 6 program using the Inet control to access a site. It used to work but now it stopped. What is causing this and how do I fix it?
View 2 RepliesI need to handle events that are thrown by Internet Explorer 8. I am able to handle events associated with the first tab that is created when IE8 launches, but I am unable to handle events if the user creates a new tab or opens a new window. I need to handle events of all tabs (and preferably all new windows as well) that are created by the instance of IE8 that is launched by my application.

I have started socket programming since last few days. I'm able to communicate when the server and client programs are run on the same computer (by specifying IP as 127.0.0.1) or on different computer which are on LAN(192.168.x.x .... etc.). But the problem is that i'm not able to communicate through internet when i provide Internet IP Address (assigned by my ISP) of computer on which server program is running.
Here's my code :
Server :
Imports System.Net.Sockets

I am making a checkbook balancer and so far so good. But, I need it to be able to handle multiple deposits or debits. The line for it is below:I need it to first do what is in the first grouping box (deposit or withdraw), and then handle the second, and then the third. Here is the coding for the Apply button:
Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I'm trying to use a asynchronous UDP-Port to recieve data on a form.I manage to receive one message at a time(for each click of btnReadData), however if I do this receive in a loop (in order to continously receive new messages), my form seems to be locked.What am I doing wrong?
Public Class FPR2DIS
Delegate Sub dDataReceived(ByVal Data As String)

I am in need of adding arr of type label at run-time. I am making a program which will retrieve employee name from database in different label. On clicking each employee name (label) it will display all the information about that employee in a msgbox. I use the following code to create the label. Since the number of labels is not fixed I have used an array.
dim withevents lblArr() as Label 'declared in the class
In the subroutine(Form load):
for i as integer=0 to NoofEmployee-1
redim lblArr(NoofEmployee-1)
lblArr(i)=new Label
' I assigned all the necessary property like size location etc..
me.controls.add(lblArr(i))
next
I declared another subroutine:
private sub MyClick(sender as Object,e as EventArgs) **handles lblArr(0).click**
MsgBox("Hello")
end sub
The code doesn't compile since a subroutine doesn't.

I am building a chat client/server. And I can connect and chat just fine, but when a user disconnects, the server does not recognize this and acts weird, often spamming the last message that was sent by the user..Also, it's like the client does not disconnect from the server even when I close the client app. Once I exit the program, VB acts like it is still debugging. Once the server is shut down however, I get this error:
IOException was unhandled:Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
serverStream.Read(inStream, 0, buffSize)I don't know how to make my client and server accept the fact that a client has disconnected...
Im basically stuck for ideas but I would like to create a program that prints i.e. I have a folder with x amount of .htm files e.g. reports that I would like to batch print. Instead of have to open each one and print in Internet Explorer I'd like to automate this process.

I want to achieve the following:
The user drags text from any open window not related to my application ( like firefox or word, for example) onto button1 on form1 in my application. when he/she does that, a new form (called form2 that contains a richtextbox) will open and the dragged text is directly copied (or inserted) into the richtextbox of the new form. button1 has allowdrop set to true. Beyond that I don't know how to proceed.
I tried:
e.effects = DragDropEffects.Copy
But it seems it is not enough.

View 8 RepliesI have installed all of the patches and Hotfixes that I can find and truth be told, this is so enigmic that i dont know where to go to.I have been working on a project for a year and just recently I went to add a database (data source) and the Tab was gone. I thought I did something wrond so i went to Data -> Data Source and nothing happens. whats funny is that I cannot do what I want and add the datasource.
I also have VS 2005 installed (which I am forced to use) and here I have no problem.
Can anyone or does anyone have a simular problem and a resolution??I really would love to use all that is available in VS08 and not having to use a much older version...
So there I was working on a project. I was putting the finishing touches on the GUI and clicked on the Image list I had added. VB froze up a moment, and when it came back I was on a code view of the form showing the properties I had just set up in the GUI. Suddenly, I can in no way view the form. I get a View code option, but no View designer. If I close out the project and open another, there it is "View Designer" right where I expect it. But in the project I was working on, it is just plain gone.
Is there something I am missing here? Can I recover my project?
If I run it in the debuger the whole form shows perfectly, I just can't get to it to edit it.
Having just downloaded the Visual Studio 2010 Ultimate Beta, I decided to code from scratch a little project I coded under 2008 VB.Net and see how it goes. However, when I click on "New Project", select new Windows Form Application project and try to open it, I get the following error dialog box & msg:
"Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.VisualStudio.Editor.Implementation.IVsGlobalUndoCapableUndoManager'. This operation failed because the QueryInterface call on the COM component for the interface with IID'{305E8709-55B7-4732-B872-1C073AB58047}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."
Anybody have any ideas what's up here, or should I post this in a different area? I tried posting this in the Microsoft MSDN Visual Basic IDE Forum but so far I have not received a reply.
