Public Sub SendClick(lnghWND As Long, X As Long, Y As Long)

My idea is to control IE instance by software
I want to solve my problems in two ways
First one is by controlling IE by mouse_event with cursorpos but not with sendmesage or postmessage API.
I want to invisibly control IE instance and click on it where I want to by sending mouse_event, but without user notice, is there any chance?
Is it possible to control IE for example in background while PC is idle and screensaver works?
Or perhaps when PC is idle detect it and show JPEG screenshot and work with mouse_event on background, so to call behind the scene?
Or perhaps in parallel user mode FAST USER SWITCH terminal service?
I don’t want to click by parsing html code body.outerhtml, tagname ("A").click
Any suggestions or any ideas with technical details?

No. You have no choice but to use mouse messages and the SendMessage API call.
This is a really bad idea. Trying to control another piece of software by pushing keyboard and mouse messages is notoriously unreliable, no matter what you do to implement the "control" method.
What are you doing with this that can't be done with the web request classes? What's the ultimate goal of "controlling IE"?

Hi!
I have a cuestion, i working in a application who must open a port to tcp comunication, i haven't any problem except if the windows xp firewall are activate, he jump and show a alert, is posible shutdown the firewall by code to what no lock my port?, thanks very much for your help.
|

Can you shut it down? No. It wouldn't be much of a firewall if any piece of software could just shutdown the firewall whenever it wanted, now would it? You can add your application and the ports it listens to the firewall using the Firewall API. The documentation is found here[^]. There is no support built into the .NET Framework, so you'll have to P/Invoke the API calls.
The Windows XP Firewall doesn't block outgoing connections, only incomming.

Now I know in ASP.Net with a DropDownList you can bind to 2 values, one that is displayed and one that is the actual value, is there a way to do this with a ComboBox in a Windows Application in Vb.Net?
"Well yes, it is an Integer, but it's a metrosexual Integer. For all we know, under all that hair gel it could be a Boolean."

I am trying to from my laptop run a program that would tell me who is currently logged into a windows 2003 Ts farm
It would be similar to the program Tsadmin.exe
does anyone have any idea if there is a way to do this via an API or in the .net framework?
Thanks

Hello,
I would like to create a patch for my program. I have a simple window app for testing. Using VB 2005. I have created the application and then added the MSI basic project.
I then went to the project assistant and added the default settings. The project built, installed, and ran ok.
Now I have made some changes to my windows application. And I want to create a patch, not sure now to do this.
I have tried using the quick patch project and the design patch configuration. I am able to create the patch and install it, but it doesn't update the windows application to show the new changes.
Once I have my patch working, should I be able to give the patch.exe to the customer, and they should be able to install it without having to uninstall? The patch should be very small as it is just a few simple changes.
Many thanks for any help you can give me,
Steve

I want to be able to click on an item in a ListBox, then using the AfterUpdate() Sub-routine, be able to store that value into a String variable. My loop is as follows:
***START***
Dim iterator As Long
Dim descriptionString As String
For iterator = 0 to Descriptions_lst.ListCount - 1
If Descriptions_lst.Selected(iterator) Then
descriptionName = Descriptions_lst.Column(0, iterator)
End if
Next iterator
***END***
I'm not exactly sure what the 'Column' does, but apparently this is supposed to get the string value from the selected ListBox item. However, it is not working. I just get empty values for my descriptionName variable. Any ideas?

I only find the ListCount and Selected properties in the Office classes. Is this VBA?

Ya, its VBA using Access. I need to somehow verify that 'if' statement properly, then get the selected item into a String variable.

Hi all,
How could i change text on button in MessageBox?
Ex : If i write :
MessageBox.Show("How to change text","Question",MessageBoxButtons.OKCancel)
-> MessageBox will be shown with "OK" and "Cancel" button. But i want to change text "OK" -> "That's right" and "Cancel" -> "That's not right".
How could i do that?
|
|
|
|
|
You can't. The things you see in a MessageBox are not cusomtizable. You'll have to create your own form class that provides this functionality. It's not that hard. It's just a normal form with a couple of buttons and a label. Maybe even a picturebox if you want.
|

|

hellllo ctlqt,
Dave is correct "The things you see in a MessageBox are not cusomtizable"
U can use
form.showDialog() method to show ModelDialog,
just create a form looklike message box and call it as modelDialog box
