Handling New Internet Windows?
Jul 15, 2009
I have a form within which has a webbrowser control. The site i view in the webbrowser control requires me to log in so i have made a one click login button which when clicked logs me in automatically. When i'm in the backend of the website, if i click on a certain button it pops up a new window that i need to make a selection from. But when this window pops up it asks me to log in again?Is it possible to catch all pop up windows so they are loaded in another form which also includes this 1 click log in to save the hassel of logging in manually again?

I successfully coded MyApplication_Startup and MyApplication_StartupNextInstance to give my single-instance application access to the command line. It works fine. if the application is not running and the user double clicks on a filetype associated with my application, my application starts up and reads in the file that was double clicked on. That's fine.
However, when the user double clicks on another file (same associated type) when the application is already running, I then (and only then) get a warning (from McAfee in my case) that my application is requesting access to the internet. I simply click OK to allow access, McAfee goes away, focus shifts to the original instance, and that instance successfully reads in the second file.
If the user then double clicks on a third file when the application is already running, focus shifts to the running application, it loads the third file, and the internet access warning DOES NOT appear. Same with all subsequent cases.
Any ideas about why the sudden internet access warning is occuring? In all the startup and load events, I do not do any internet related things. Much later, the program will send an email, but that code is far removed from Startup and Load things.My only idea is that perhaps because I have "awakened" the normally hidden ApplcationEvents.vb file (by putting some code in there), maybe I have triggered some sort of handling of the MyApplication_NetworkAvaialabilityChanged event, even though I make no reference to this event anywhere.
Before I added the command line handling stuff, I noticed that the internet access warning would occur only once for each new build. Susequent execution of the same build would not trigger an internet access warning. So now it is as if the handling of the StartupNextInstance event is simulating starting up a new build for the first time. Weird.
One more thing. I am not deploying this over a network. I am making a simple .exe by selecting Build from the MVS 2008 menu, then running the .exe by double clicking on it from Windows Explorer. I am using Visual Basic 2008 Express on Windows XP.

If GeBrowse.DownloadString("URL GOES HERE").Contains("CHECKS FOR TEXT HERE.") Then

I am developing a windows based application in VB 2005, the main form of the application is of fixed border style (i.e. user cannot resize the form), but in certain cases I am resizing my form through code. Intially the form has a fixed height i.e. 350 for normal height and 400 for extended height. But in this case the problem could not be solved effectively as the user can have different DPI setting e.g. 120, 144, 192 etc.The logic I implemented is to divide my form (vertically) into 3 parts

I developed an assistance programme for an online game, and, in response to the users demands, I developed a secondary programme that downloads a zip file from a webpage hosted in a free Geocities server with the latest update for the programme and applies it. With the WinXP users it has worked perfectly, but with the Vista users, I've had a few cases where the update programme wasn't able to download the update, although everything worked fine with other uses.

I have various input textboxes on my form. And based on entries made in each of the input textboxes, I update the display textbox. However, using AppendText message of textbox. I have my input textboxes set to accept only numeric values. So for each character inputted correctly, I update the display Textbox. Problem I have is when user selects Key.Back or Key.Delete, what I would like to do is do a Delete of last character in the display textbox, but I am yet to get this right. How do I delete the last character in the string that is contained in a TextBox using AppendText()

I'm using SHDocVw.InternetExplorerClass to scrape a webpage. It works fine in XP, but when I try to run it in windows 7 I get an error:The interface is unknown. (Exception from HRESULT: 0x800706B5)
When I run visual studio in administrator mode it works fine, but the published application has to be run in administrator mode too, which isn't acceptable.
Is there any way to get around running the application in administrator mode?

we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

I heard that there is two way to handle SMS for programming. One is to purchase a GSM Modem 2nd is to use 3rd party online web service.Which is the recommended one if I plan to implement the program in VB.Net and send the message internationally. As I have a function that is require to send sms where it reach certain times, so I most probably will need some API to do that.

I'm completely confused about the event handling. I read some articles about it but after it I just get confused to write and use them in my classes.This is my class i. e.:
[Code]..
I dont have any argument passing. But I want to know how should I do it too. And I wanted to know if each instance of the Test class, run this event separately I mean each instance by themselves, This event AnEvent() will occur? Cuz I have lots of instances from my class.

I am developing a COM dll library, and I have a little vb.net (vs 2005) application just to test it.I had my object declared in the application as
Private m_VarName As MyLib.CMyComClass
So far, so good.But now, I need an event to inform the application of some things, so I implemented such event in the COM dll, and changed the declaration to
Private WithEvents m_VarName As MyLib.CMyComClass
So far, so good, again. But if I add a Sub to handle my event:
Private Sub m_VarName_OnCaptureStop() Handles m_VarName.MyEvent
..
End Sub
The first time I create the object, nothing bad happens, but if I reinstantiate it
If (Not m_VarName Is Nothing) Then ReleaseComObject(m_VarName)
m_VarName= New MyLib.CMyComClass
then I get a cryptic TargetInvocationException, seemingly related to reflection (which, AFAIK, I am not using).If I remove the "Handles m_VarName.MyEvent" part, everything seems to work. In case it matters, I am not firing any event, for now.
