so you want the code to occur under the click events of the labels AND the checkbox..?
ok here you go
Private Sub MyHugeEvent(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click, Label1.Click, CheckBox1.Click
If CheckBox1.Checked = True Then
CheckBox1.Checked = False
Else
CheckBox1.Checked = True
End If
End Sub
NOTE: you MUST set the AutoCheck property of the checkbox to FALSE.

i want to invert a color..for example...inveret color.blue
how can i do it?
|
|
|
|
|
The inverse of blue is 0xFFFF00. To invert a colour you need to invert the red, green and blue components individually.

To be honest, I don't use VB at all. If it's VB.NET, then you take the Color variable, and you say
myColor.Red = 255-myColor.Red
myColor.Green = 255-myColor.Green
myColor.Blue = 255-myColor.Blue

Thanx to all
You Can see a code for getting R ,G ,B from a color and inverting a color in this address:

Best solution to my Question!
Public Function InvertColor(ByVal C As Color) As Color<br />
Return (Color.FromArgb(255 - C.R, 255 - C.G, 255 - C.B))<br />
End Function<br />

Hello,
I am writing a program and i need to catch the change clipboard msg to start a event.
The program is a ScreenDump program so you will understand this short qeustion.
I know how to put and get data in or out the clipboard. maybe you can give me a code sample on how the change clipboard msg works after pressing toe Snapshot key.
thank you in advanced.

I'm a bit confused...
You're already putting the data on the clipboard and taking it off? If that's the case, why would you need to detect the change in the clipboard? BTW: There is no clipboard changed event...

Are you saying the when a user presses PrtScrn or Alt-PrtScrn, you want you app to be notified that there is something new on the clipboard?
If that's true, now I understand...
Ummm...OK.
Your going to have to override the WndProc function in your form to receive the WM_DRAWCLIPBOARD message and process it. You'll also need to process WM_CHANGECBCHAIN too if other applications register as clipboard viewers, you can repair the end of the chain if your suddently the last in the chain. You'll need to use the SendMessage, SetClipBoardViewer and ChangeClipboardChain functions, in user32.dll, and GetLastError, in kernel32, to handle this.
What your going to do is when your app starts, call SetClipBoardViewer with the window handle of your form. You'll have to save the return value as this is the handle of the next window in the clipboard viewer chain. Next, call GetLastError to see if what you got back was an error or a null handle.
Now, in you WndProc procedure, when you get the WM_DRAWCLIPBOARD message, you can use the standard .NET Clipboard functions to get the image from the clipboard and display it in a PictureBox if need be. You'll then need to use SendMessage to send the same message you got to the next window in the chain, (remember that return value from SetClipBoardViewer?) unless it's null.
Now, you may be wondering why you have to handle WM_CHANGECBCHAIN. This is because if the next window in the chain is the one that your supposed to send the WM_DRACLIPBOARD to, you'll need to know that it's been removed and you no longer have to send that message, or you'll need to send it to a different window now.
.
.
I've lost you, haven't I...?
Last but not least, when your app quits, you have to remove yourself from the viewer chain. This is done by calling ChangeClipboardChain with your window handle and the window handle of the window your supposed to be forwarding WM_DRAWCLIPBOARD messages to.
Simple, no?

That's because there really isn't any. Registering as a clipboard viewer is not a common operation at all. You'll have to piece together example, like overriding WndProc and calling into the Win32 API.
But, there is no simple way to do this. There is no event that is fired when the clipboard changes, so you have to go thru the Win32 API pain of registering for notifications yourself.

Hello guys i need your little help plz

In summary, then:
You want free source code (in VB suitable for VB.NET) to implement a ruler control like the Office one (or the one in wordpad), and you want us to provide it, but you can't even be bothered to occasionally read the discussion board.
Why does a certain two-word (in English, at least, it's two words) phrase involving sex and travel spring to my mind* ?

I wonder if the words you're thinking begins with F and ends with f? 
Sometimes I feel that the people posting questions in the forums should be a little bit nicer and clearer.
I personally wouldn't help people that are rude and/or imposing, even if I had to I'll do it grudgingly.
Come on people, be nice and you might get help sooner and better than you had expected.

I'd like sex, lots of it, with women from all over the world, but I don't want to travel, I want them to come to me, every hour of the day, every day of the year.
Come on girlz, give my little thing, ur help! 
I wonder if I post this, will any geeky women reply. No, better delete it, before I press the post button by accident and my wife kills me.

hi Guys..
here is a place for discussion abaut programming problems!

What's the best way to trap special key combinations. For example, if I want to develop a control that responds to ALT+S, F4 etc., by setting this key combination as a property. Should these key combinations be pumped from the form to controls or should the controls listen to the key presses being sent to the form?

Hello,
For some reason, I'm getting a Common Language Runtime Error when loading certain vb.net applications on my Win 98 machine. For example, I've tried to build certain sample files such as Music Trivia & Lucky Seven and tested on my Windows 98 machine. The Music Trivia application ran fine. The Lucky Seven app did not. I'm getting a Common Language Runtime Error when opening the application. I've loaded the .NET Framework and it seems to be working fine (the Music Trivia app is working). Does anyone have any ideas why I'm having this problem?
Thanks so much for your help!

After converting my app from MSOffice 97 to MSOffice 2002 i get an error message 3021 "No current record" when opening a report. The attached query runs fine with no errors. The report opens after a few dozen 3021 errors with a few readable records and the rest #Fout (or #Error which means the same). Anyone?
Grtz,
Guus

First you have to tell us whether your app is a Word Macro, Excel Macro, Access Project, VB or something else.
If they are office application (especially Access), there has been major changes on the methods from Office97 to OfficeXP and most likely you have to debug and rewrite your application.
I had to do this for many Word Macros and Access Projects. If you're lucky, you only need to make a minor modification.
Good luck!

[EDIT]Doh!  I didn't read the title.  Yes, you have to debug and rewrite your Access application.[/EDIT]
