I know you have to use WM_EXITSIZEMOVE or whatever it is, but I'm just not really sure how to use messages properly...I've read a few things online but just can't get it to work properly.
I'm looking into making child forms dockable inside my parent form and want to know when to hide my dock labels again (after the child form has stopped being moved).
We have made a service in vb2010, how can we detect that the service is stopped by hand?
We know the �Protected Overrides Sub OnStop()
I need to detect shift + arrow key in blank form. But it's not working. I also tried overriding IsInputKey method but it only detects single key press (like arrow key) but when multiple key are pressed it simply doesn't work.
View 5 RepliesHow would i go about stopping a form from being moved. I have the form border style set as FixedSingle and would like to keep it this way because it looks good in vista :)
View 10 RepliesPretending I have a class that inherits off Control, how would I handle the parent form's Resize and Move events within the control? I have a painting glitch that happens when the form is resized or moved. Right now in the form I just have:
vb.net Private Sub frmMain_ResizeMove(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles Me.Resize, Me.Move Me.Refresh()End Sub
But this can't be the proper way to do it, considering Refresh() invalidates all children (will be slow and flashing if the form has lots of controls). I want to basically do the above code inside the control.
Edit:This is the glitch after a resize of the parent form:
And this is what the button is supposed to look like:
Also, I experience this issue if something like a message box is dragged over top of it. How can I remedy these issues by forcing a repaint?
there is any event or way to detect activity in an form or project?in the form and all the child controls.
mainly mouse clicks (not mousemove) and key press.
for example, if the form have not activity in the lasts 10 minutes, do something.

All the tooltips in one of my apps stopped working. I checked the component; the settings are all the same as on another app that still works. what would cause tooltips to suddenly turn off?
View 9 RepliesAll of the sudden none of the pre programmed buttons on my form work anymore. The only buttons that do work are those i create in runtime.
I allready replaced all my buttons with new buttons.Beacuse i thought maby i've changed something in their settings. I've put breakers on the Private Button_click subs to see if anything happens. Nothing absolutly nothing happens if i click my pre programmed buttons.
Update: Well i figured out what was wrong. VS2010 had removed all the "handles button.click" behind the subs. And it won't create them when i dubble click a button i program time.
I'm using the following code
' Visual Basic
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
[CODE]..........
Its straight off the Microsoft site found here: [URL]
When I add the required components and click on the button, my app simply disappears, closes, goes right back into a stopped state. No errors, No Warnings, No issues. Nothing. Its as-if there is a stray "END" just before the IF statement. (But there isn't) Its stopping right at the IF statement. My app (THEIR CODE) just makes it disappear and "Stop". The code was working about an hour ago, but now nothing, and thats the only code on the project.
I am trying to find out if anybody know if tab pages on a form can be programmed to be moved by the user. For example I have 3 tab pages on a form and I was wondering if the user wanted to move the first tab page to the last and so forth, is the way to allow the user to do this?

Basically what I want to do is create a program with a simple interface where you select one or more directories, and it'll look for files that are in the directory that aren't currently in a folder, and make a folder to house the file in, with the same name as the file. But if they're already in a folder, I want the program to ignore them.Videos folder, there's 3 videos that aren't currently in a folder, 1 that is.Video A, Video B, and Video C.I want 3 folders to be created, and I want each file moved into the corresponding folder.I want the Video D folder/file ignored.I know how to do this in DOS but I'm having trouble translating it to VB.In DOS you would navigate to the directory and enter:FOR %i IN (*.*) DO (IF NOT EXIST "%~ni" MD "%~ni") & (MOVE "%i" "%~ni").I have no clue as to where to start.

View 1 RepliesI'm using VS 2005 and .NET framework 2.0 SP2 to build an application with a datagridview in it. I'm using Microsoft Word 11.0 Object Library to do the spelling checker on one of the field in datagridview. When it detected a spelling and grammar window would pop-up open on top of the datagridview.
The problem I got was when I moved the pop-up window to the new location, there's still an image of the pop-up window left behind the previous location. The more I moved the more of those copied image would be created on screen.

View 1 RepliesWhy are my new (moved to) text files deleting after the move?
If TextBox1.Text = "* DISPLAY SCROLL 10 *" Then
Dim D10A As StreamReader = File.OpenText("LINE 3 UNITS.txt")
D10A.Close()
[code]....
the file "line 3 units.txt" contains 3 choices. what I need to do is write one of these selections to the new file "line 3 units new.txt" then recognize the contents of this file to control a boolean statement.
Dim W As String = (D10B)
If W.ToLower.Contains("load") Then
LIN3LD = True
[code]....
I end up with 2 known problems.
1) The new text files delete
2) if the file doesn't delete (for whatever reason) the CONTAIN statement doesn't recognize either "load" or "speed"

View 1 RepliesI have a Windows vb.net project that does an occasional "auto refresh" based on a 20 minute timer. I want to avoid any type of auto-refresh... if the user has manually had any interaction with the program (mouse move, click, keystroke, anything) in the past 5 minutes.
I added a global variable "Dim g_LastActivity As Date" so the timer can detect that 5 minute mark.
Is there some place to put my "g_LastActivity = NOW" line that will ensure it will happen during ANY user activity? All mouse clicks, on all buttons, all mouse moves, anywhere, all keystrokes, basically EVERYTHING.
I am having a problem where I am on a text box and try to click a button that will bring up some reports. Since my cursor is still on the text box it doesn't go through the "Leave" and so what I entered into the text box is not saved (this happens in "Leave"). I have read previously not to use "Lost Focus" because it causes problems when you leave the form it triggers the "Lost Focus" on on the fields and just in general to use "Leave" rather than "Lost Focus". Is there a way to force my way through the "Leave"? I also don't know which field my cursor could be on (there are probably 20 text box or combo box fields on this form.

I need to call a sub to handle the resizing of text in relation to the new size of a form or control. I have found that setting a minimum height and width works behind the scene so I figure there must be something watching the form size but can't find what or where it is.
