I have a program that locks the desktop when loaded and will only close if a username and password is entered.
the problem i am having is that once the user presses alt+tab or even the windows key the other apps are accessed.
how can i get my form to ignore any hotkey input.
In Windows it's possible to Increase the size of on-screen fonts. We realized that too late and if a user does this our programm is unusable because he can not see all texts and controls. We're bringing out a release and we do not have the time to fix that.
So: How can I disable or ignore this increasing from windows application-wide? I tried setting autoscale to none but it is not working. Isn't possible to ignore that setting for the whole application? How can I do that?I know that this is a week solution because the user has a reason why he wants to increase the font size. But we can not fix this problem within two weeks but want to provide an application somebody can work.
Whenever a person adjusts how big they want there display, it will distort my application, it will make images overlap and will make text bigger.
Is there some code I can do to tell my program to ignore the size set by the display on windows?
I have a windows application that has a tab control with 5 different tabs. Each of these tabs has a datagrid view that is populated with data on form load with data from SQL Server. I have an event handler for the datagrids for CellValueChanged that appends an asterisk, "*" to the tab, when a change is made, this is meant to mimic the same behavior in VS or SSMS. The issue that I have just realized is that on page load as the datagrids are populated this event handler is raised thousand of times. I have included an If Then statement to exit the sub if it occurs during page load, but am concerned about the performance implications, if any. Is there a better way to handle such functionality? Possibly a way to ignore the event handler on form load? If not is there a negative impact leaving this functionality in?

View 7 RepliesI seem to have a bit of a problem with the ICShartEditor text editor. It works fine for me in a Windows Forms app, except that if I have a button (or any other control) on the same form that defines a hotkey (like ALT-S for a Save button), then whenever I try to type 'S' in the text editor (or whatever the hotkey might be), then it triggers the hotkey rather than adding the character to the text.What appears to be happening under the hood is that all the ProcessMnemonic() methods for all controls of the form run, so those methods kick in and handle the keypress, which I would think should only happen if a key like the ALT-key is pressed.

View 5 RepliesI'm trying to get hotkeys to work in my application (to make it visable if its minimized). I got it to work except that they only work once... the second time you try it does nothing.
here is the code i was using

MOD_ALT = &H1
MOD_CONTROL = &H2

how I would make hotkeys e.g "ctrl + 1" to do an action even when the application ism't the active window.
for example I am working on photoshop and then i press ctrl + 1 and my app appears in front of it.
or if I press "ctrl+2" a new window will open.
I need this to also work when the application is hidden and in the system tray as well as when application is visible
Now my question is, is it possible to use Hotkeys and ScreenCapture in a Fullscreen game?If so, how?What im acutaly trying to do is a program to take a screenshot ingame (for some reason, this game doesnt have an option to take screenshots ingame.. Bad Company 2)
View 7 RepliesI have been trying over the past few days to make a program sit open on the computer, waiting for a key press (which will be the hotkey). When the key is pressed, it will execute a peice of code and minimize itself. Im really sorry if this is too simple but im stumped over this one. I have searched google alot but no luck
So: I need to know how I can have the program 'monitoring' or 'looking for' a certain key press while it is doing something to tell it to stop, bearing in mind when the program actually starts it will minimise and stay minimised untill this hotkey is pressed that makes it maximise itself and stop the program.
How do I make hotkeys for buttons, which will activate it, like I pressed the button?
View 4 RepliesI've written a simple WAV player in VB 2010 - a Windows Form App with no menus. I'm trying to create a hotkey, like CTRL-D that would make a text box visible. Typing the correct password in the box will expand the form and show some Administrative functions. I'm having issues creating the hotkey with more than one key.I've got the following code, but it does not work. I do have KeyPreview set to True.
Private Sub _KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Control And e.KeyCode = Keys.D Then
txtPWD.Visible = True
I've also tried
If e.Keycode = Keys.ControlKey & e.KeyCode = Keys.D
and many other variations including changing to ALT and SHIFT but nothing seems to work. If I remove one of the Keys, it works just fine.

I'm trying to make a prank program that registers all of the letter keys on the keyboard and then will make random message boxes pop-up when you press certain ones, or just re-arrange the letters.But before adding any pranks, I'm trying to just get all of the hotkeys to work like a normal keyboard because when you register a key to be a hotkey, it no longer works for anything else. So registering "e" in the program will cause "e" to do nothing when your in notepad or something.
So far I've gotten pretty much everything to work except for this weird Shift bug. Whenever I press Shift and then a letter, the Sendkeys will correctly send the uppercase key, however as soon as I release shift and press a key without it, it still keeps the uppercase for one more letter.So if I press Shift + E then "E" will be successfully sent to Notepad, but then if I just press "b", "B" will be sent instead, but then after that first error it will successfully send lowercase again.
I was using wordlabel to store the letters so as to see if the shift uppercase problem was something in my coding, but actually when I press Shift + A and then just press a, it will do Aa in the label but AA in a program with the focus, like Notepad. So I don't know if this is a problem with Sendkeys or what but does anyone know of a solution?
How would I use "custom Hotkeys"? For example, if my textbox's text is F5, then how would I use GetAsyncKeyState to get "F5"?

I am trying to input the function key that a user has selected from a ComboBox (containing the function keys F1~F12 as options) into the GetAsyncKeyState(). However, since the ComboBox_StartHotkey.Text is a string, it cannot be converted into Long data type needed for the GetAsyncKeyState() function. I have tried Conversion and Parse Methods but what I try doesn't seem to work. Anyone know how to effectively convert a String (such as F6) into a Long data type for using in the GetAsyncKeyState() function in this case?
I used the tried to use the ItemData property to hold the Key Code representing the Function Key.
Using the code from this thread, I have been able to successfully register hotkeys for myself. I am having trouble though, I am trying to register a hotkey with the Control Constant; it doesn't seem to be working. I need to register Control + 1 (MOD_CTRL, Keys.D1). I know how to do this, yet I can't seem to get the MOD_CTRL constant to work. I've found that the constant for Control is &H11 but as I said previously, this does not seem to fire for either the left control or right control keys.

I have a small app with one form (form1) which is supposed to be hidden until a hot key combo is pressed. I have read and taken sample code from: [URL]. I do have a keyboard class that hooks keyboard input, (I have my reasons) but it's odd that it will recognise the first hotkey and fire the event, but none after that? The problem is, I can make the form show, but not hide again. It will only recognise one shortcut, one time. How do I make it respond to another hotkey combo? Is the handle changing? Even with focus, the enabled form is not hiding again.
View 4 RepliesI would like to register a hotkeys/shortcut keys (e.g. Ctrl + Alt + A) and I would like to find out if other program is using it.
View 2 RepliesI was wondering on how i can make multiple global hotkeys and have them show message boxes just so i can learn and expand from there. Like have one be ctrl + alt + F1 and the other be ctrl + alt + F2.
View 1 RepliesBelow is the section I'm having trouble with at the moment:
Friend Sub glbHooks_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) Handles glbHooks.KeyPress
newStr = newStr & LCase(e.KeyChar)
[Code]....
Neither of these worked, though the 2nd one would clean up my code a bit. Unfortunately I'm getting an "Expression expected" error on that "newStr = If..." line. I know there's supposed to be a "Then" somewhere along it but I don't know where it's supposed to be and the poster hasn't gotten back to me on that yet.
I'm working on a project that contains hotkeys, but I don't wish to have global hotkeys. At the moment, I'm using KeyDown and e.KeyCode for hotkeys. I've created test projects where these worked perfectly fine, but on my main project, they don't register.
CODE:
1)I have saved some data in a text file, now I want to assign it a hotkey, so that when a user presses the hotkey (assigned by the user) that file data should be displayed in a text editor or email etc.
2) should I save the text file and hotkeys into database? if yes then how? I am totally new to program.
I have made a application that detects already saved hotkeys and data assigned to them, so now whenever I press the hotkey to send the assigned data to active window it does sends the data to active but it won't stop sending data...I am calling my function that reads data from the database in timer device and the function that detects the hotkey...
Here is my code
Private Sub Hot_Checker_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Hot_Checker.Tick
gKey.CheckBox()
'is the object that calls the function to check the pressed hotkey
keyTemp = gKey.getHkey()
[Code] .....
trying to find the main error that is causing this to happen, after pressing the hotkey my app won't stop sending the data to the active window. My app should wait for the next hotkey press rather than sending data.
I want to make hotkeys for my project, it needs hotkeys to complete. how to make hotkeys even if it now focused on form1.
