Forms :: Capturing Forms Using Sendkeys?

Jun 18, 2009

my program at the moment will capture forms using the sendkeys command, I use the

SendKeys.Send("%" + "{PRTSC}")

why I can capture the current form sometimes and then other times it wont capture a current form depending on the appllication that is running the form. Is there a way that applications can hide from having a screen capture as it only works with certain applications, for example the visual studio forms, explorer or firefox browser, any windows form etc it works fine. I am able to pick up the thread and title name of any form but can't capture every form, some are dismissed.

The rest of my code looks like this:

Public Class Form1
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
'clear clipboard

Forms :: Capturing Values From Two Lists Boxes During Drag And Drop?

Oct 5, 2011

I have two list boxes. A users selects a value from each, clicks a button and the application creates a relationship between the two selected items by saving them in an array and displaying the relationship in a third list box.

What I want to allow is for users to be able to drag a value from one list box and drop it on top of another value. I have the code to capture the value of the item dragged but I don't see how to capture the item that the data is dropped onto.

Is there a way to capture the targeted selected item?

Forms :: Sendkeys For SendKey To Password Field On A Second Form?

Sep 25, 2009

I have created my own virtural keyboard for a touch screen interface. I used two forms,one for the main program and one for my keyboard so the keyboard will have opacity of 90%.in my main program form's login screen, i have two textboxs, one for username one for password. the password is a textbox with UseSystemPasswordChar property set to True.I used the technique descripted here: How to: Simulate Mouse and Keyboard Events in Code to send a keycode to different form window.

1. get window handler using FindWindow()
2. set main program form as focused window by SetForgoundWindow()
3. then sendkeys.send(keycodes)

it worked perfectly when i try to input letters to the username by the virtual keyboard, but it not really working for the password textbox.Strange when i set the password textbox 's UseSystemPasswordChar to False again it worked. if i put my virtual keyboard as one of the controls of my main program form it also works but i then don't have the opacity property for my keyboard. of course, in this case the Findwindow() and setforgroundwindow() is not needed.

Application That Has Multiple Front Ends Developed Using Windows Forms / WPF / ASP / Compact Framework Mobile Forms

Apr 9, 2010

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.

Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

VS 2005 - Gotchas With Docked Forms - Forms - Displayed Using Menu Items To Display Information To User

Nov 10, 2011

We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?

Passing Data Between Forms Without Any Public Methods Or Properties On The Forms

Dec 28, 2009

Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.

' File Definitions.vb

Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)

Public Class MessageEventArgs : Inherits EventArgs
Public Message As String

[CODE]...

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.

VS 2010 Coding Forms - Creating Some Forms And Message Boxes?

I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

Forms :: Command Line Args In Windows Forms?

Aug 2, 2010

I was playing a game recently and saw that they could use args in the shortcut, and I decided to try to impliment this into my application...so far, I got: (runs this sub on load)

Sub startup_args()
If Environment.GetCommandLineArgs.Contains("+game") Then
Dim path As Array = Environment.GetCommandLineArgs

[code]....

just to see what it returns, but the application crashes. I also tried path.tostring(), but that didn't work. When I did:

If Evnironment.GetCommandLineArgs.Contains("+game") Then
Dim path as string = Environment.GetCommandLineArgs.tostring
MsgBox(path)

but that returned the value "SString.Array[]"...

Multiple Forms Program Needs To Open Successive Forms Somehow?

Nov 3, 2009

i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?

Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.

What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.

VS 2008 : Get 2 Forms To Close At Different Times Using A Timer On Each Of The 2 Forms?

Apr 21, 2010

i have a problem with trying to get 2 forms to close at different times using a timer on each of the 2 forms.

This is my form layout:

Quote:
frmMain
Frm1
Frm2



Frm1 and Frm2 are identical to each other. FrmMain has 2 buttons on it. One button to call Frm1 and the other to call Frm2.Frm1 and Frm2 each has a timer. It counts down to 0 and then does a .close(). However, if i pause between clicking the second button they both seem to always disappears at the same time.I would do something like this...

Click on the first button (showing the Frm1 form)

wait about 10 secs...Click on the second button (showing the Frm2 form)they both are shown on screen...hen they both disappear at the same time.... which shouldn't happen since i clicked the Frm2 box 10 seconds AFTER Frm1... So Frm1 should hide before Frm2 does...but it does not.
