I have a VB.net MDI app that contains a modal window (normal window shown as modal). I have a custom title bar button that disappears if the user clicks outside the modal area.Normally, clicking off a modal will cause the system to beep and then flash the title bar of the modal window.
View 2 Repliesis there any way to determine if a button is still blinking? because i have programmed it like when the condition is true, the button will light up. This button will stop blinking only when the user clicks on it. Because in my program, each button represents the number of blocks. So if the alarm comes in from the block one and block one button blinks, the user should press on the button to acknowledge the alarm. but while the block one button is blinking,if a new alarm comes in from block 2 before the user click on the button1 to stop it from blinking, button 2 will blink together with button1 because the user has not acknowledged the alarm from button1. Currently, i have written the below code to blink the button. but this one will go with the alarm, that is if the alarm comes in at block 1, the button will lightt up at block one. but when a new alarm comes in at block 2 before the user acknowledge the button1, the button1 will stop blinking and buttton 2 will blink. But i want both buttons to light up. the code is below:
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
For Each ctl As Control In PictureBox1.Controls

May I know if is there any way to check if the button is still blinking from the button class that I have? Cuz I used this method to check 'which is if the button is still blinking execute this this this...

Label4.Hide()
Label5.Hide()

How do you detect the title bar's height?
OR
How do you set just the height of a form without the title bar's height included in that?
I am trying to get the active windows title bar text, such as right now it says (Start a New Question or Discussion - Windows Internet Explorer). How would I grab that text?
View 8 RepliesI am developing an application in Vb.net 2008.In it I wish to add a conformation message box when ever someone attempts to close the application window.So I want to detect that some one has clicked on close button which is present on title-bar of my window.
View 3 Repliesborder of that said window so the only place the mouse can't click the titlebar and the minimize,restore, and maximize button. The height of the titlebar depends on what OS the user is using so I'm having trouble because I can't give a definite value for this. How do I detect the height. and also for border i'm not sure if the borders have different widths with different operating systems. I'm using windows XP on classic mode, when I change to the themed mode, the height of the title bar changes so it won't work.

I'm using the WndProc To get messages about USB flashdrives connecting and removing from the users computer. It works grand. I also use WMI queries to get the info about the flashdrives. It works as it shouold. The problem is when both of these are in the same solution. I ended up creating an extra .EXE that uses the WMI queries to get the drive info and output the info to a CSV file which my Main will parse. I tries creating a seperate class of each and i also tried to make a DLL that I import to no avail.
View 4 RepliesCurrently im trying to write a HotKey class, however in order to intercept the messages you need to overwrite the WndProc and check for WM_HOTKEY.
Currently, im using Inherits Form inside of the class, so that it has the option of overwriding the wndproc, but along with that I get all the forms normal events when trying to handle it.
Below is my

I've overriden the WndProc of the ComboBox and I am drawing my own combo box, a code snippet is below:
Protected Overrides Sub WndProc(ByRef m As Message)
MyBase.WndProc(m)
Select Case m.Msg
Case &HF

Though the old control is still being painted as my drawn combo box is just overlapping the old drawing. Is there a way to stop it drawing the default combo box?
I'm inheriting ComboBox and want to implement some special processing for Copy/Cut, I have the code below to handle it, but unfortunately the Copy/Cut message code is not sent to WndProc. The same code is working properly in inherited TextBox.[code]....

I have a class that inherits the Textbox class. My main goal is to prevent specific keys from being entered into the textfield. Now, I have a solution however I have one issue with it.
[Code]...
I'm creating a base class for a button that inherits from Control as opposed to ButtonBase.
I'm using reflector to look at ButtonBase to make sure I don't overlook anything important and I'm puzzled with the contents of the WndProc method. There's checks in there for things like button up, click and capture changed, which as far as I can tell are all handled within the relevent 'On' methods of the class.
I am attempting to detect addition/removal of volume media in a Visual Studio 2005 project. I can get this to work using the WndProc message WM_DEVICECHANGE on all types of volumes except SDHC (Secure Digital High Capicity) cards. Is there another Windows Message I have to listen for? If so, what is it, and what else do I have to do?

Does anyone know of a solution using the internal webbrowser, to grab a sites <title></title> tags?

I made a Vista Aero -style form for XP, but when using it, the application won't close. The FormClosed and Disposed events fire, but not the HandleDestroyed event. I tried to get around that by handling the Disposed event and calling Me.DestroyHandle(), and it worked, but not if the user resized the form so that it caused an IndexOutOfRangeException in BlurImage().The code is attached.

View 1 RepliesI'm developing a program where I've had to add a keyboard shortcuts system. The problem is it uses a third party OCX for a part of its display, and it is catching some essential WM_KEYDOWN messages when in focus, like Ctrl+C, Ctrl+V, etc. I've tried catching the WM_KEYDOWN message through WndProc, but the message is not propagating, so I guess the keyboard messages go from the inner container to the outer one, don't they?
The WM_KEYUP messages can be caught tho, but I'd prefer to be able to catch some of those messages on the KeyDown event. I'm aware I could make some low-level hook, but I'd like to avoid this workaround. Well, if the WM_KEYDOWN message goes from the OCX to its top level container, I guess I'll have to treat those key combinations in the KeyUp event.
I am capturing a few system command messages (namely minimize/maximize/restore). Inside the WndProc override I am trying to change the form's Me.ShowInTaskbar value but it is causing weird behavior in that minimization and restoration does not occur properly.Can anyone think of a reason why changing this property would interfere with this? The reason I don't really want to post code is because duplicating the effect takes a bit of code/setup. My initial thought was that changing the property's value is somehow sending another windows message and canceling the one I am currently manipulating. I realize this is a little vague but it's a shot in the dark.
View 1 RepliesI am trying to wrap my head around getting some blinking colored text and lasting for 3 seconds on the screen. I'm creating a game where you hit submit and if the answer is correct a label with popup and blink 3 different colors for about 3 seconds also a groupbox background color change. I have found many different ways on here how to do the blinking text. I just can't figure out how to do it for 3 seconds and then disappear. Here's a general idea of the code
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

i want to blink any of the for labels if the back color is LimeGreen.Timer5 is enabled already and starts at form closing event of another for.so on the timer tick i have below code.

If (time2 = 1) And Label17.BackColor = Color.LimeGreen Then
Label17.SendToBack()

View 1 RepliesHow to make the Button.Text Blinking?
View 7 RepliesIn my form, there are many controls and the people who will use the final program are not very computer literate people. For this reason, I would like to use arrows which blink beside the control in order to show the order of controls to use (just like a visual guide). I also make the controls active-inactive in a proper order but a visual guide will also be musch of use...I guess I can do this by either using picture boxes beside each control or draw method (which I do not yet know how to use). But if I use a picturebox, how will I give the blinking (or fade in & out effect)? For blinking effect, should I use a timer or anything else?
