.NET provides EventLog class that be able to write application event information to a particular log on the system. Is there simliar Win32 API that can be called with C++?
Hey guys,
I'm trying to sho a contextmenu on right-click on an item in a listbox. So i'm binding a list of "Users" to my listbox. Then i'm a bit lost. I thought i could foreach the list and add a mouserightdown event on the listboxitems, but i can't figure out how.
Is this a good way, or does anyone know a better way of accomplishing what i want.
Thanks in advance.
Consider this code:
public class StateChartPanel extends JPanel {
private LightContext LC;
public StateChartPanel(LightContext lc){
LC=lc;
}
public void paintComponent( Graphics G ){
super.paintComponent( G );
LC.DrawStateChart((Graphics2D)G);
}
}
StateChartPanel is a panel to draw something (a state chart). It sends its Graphics object to LC which use it to draw shapes but whenever it draws something the PaintComponent event of StateChartPanel happens again and it causes my application to hang.

Hi All
I'm sure you're all aware of the fact that the Label Control has no KeyDown handler (and why would it?)... Anyway, I'm in need of a KeyDown handler for the Label Control and would appreciate any pointers/suggestions to get me started.
I've searched around but haven't found any info on creating my own Event Handlers for the Label Control. Can this be done is C#?
Thanks
Hi, I have a Firefox 3.6.2 problem (3.5.x works just fine).
This is the code:
...
var newImage = new Image();
newImage.onload=function() {swapMapImg(newImage);};
newImage.src = newBackground;
...
function swapMapImg(newImage) {
alert('bingo');
}
Firefox 3.6.2 no longer fires off my onload event, any ideas?
When i click a button my main window i want it to become transparent to keyboard and mouse events, i.e. all keyboard and mouse events should pass to any windows below it as if that window is not present there.
"Qt::WA_TransparentForMouseEvents" does not work here as this only make child windows transparent to keyboard and mouse events i guess. And my window is main window and i want to pass all event to any window on desktop not just parent window.
Is there an event which will get whether the user has moved his finger outside of the button?
Kind of like TouchUpOutside except without the "up" bit.
Like how the iphone keyboard, the letter gets smaller (back to normal) as you move your finger of the letter.
There are a few buttons associated with the Output window in Visual Studio (VS2005/2008/2010). One of them is "Clear All Panes".
How can I install an event handler that's called when that button is clicked?
I'm building a Visual Studio extensibility package, working in C#.
I have a embedded chart and I want to modify the behavior on the mouseDown event but only when it occurs on a dataSeries (xlSeries). But for all other elements (axis, plot area, gridline, etc), I want it to fall back on the default mouseDown behavior. Is this possible?
Thanks.
I have an aspx that has the following javascript function being ran during the onload event of the body.
<body onload="startClock();">
However, I'm setting the aspx up to use a master page, so the body tag doesn't exist in the aspx anymore. How do I go about registering the startClock function to run when the page is hit and still have it use a masterpage?
I don't even know if a solution exists or not. Here is the problem in detail. You are a program that is accepting an infinitely long stream of characters (for simplicity you can assume characters are either 1 or 0). At any point, I can stop the stream (let's say after N characters were passed through) and ask you if the string received so far is a palindrome or not. How can you do this using less sub-linear space and/or time.
I have a listview that generates thumbnail using a backgroundworker. When the listview is being scrolled i want to pause the backgroundworker and get the current value of the scrolled area, when the user stopped scrolling the listview, resume the backgroundworker starting from the item according to the value of the scrolled area.
Is it possible to handle scroll event of a listview? if yes how? if not then what is a good alternative according to what i described above?
I would like to know if my .Net code can write into Windows log--Application part of the Event Viewer on Windows 2008 server and Windows 7 if I am a Non-administrator user.
Hi. I'm writing a game in C++, and I'm trying to get it to recognize keyboard and mouse events. Google tells me that boost.signal is suitable for event handling, but none of the code samples or tutorials I've found tell me how to associate a keypress or mouseclick with a function. Can anyone shed any light on this?
In Silverlight, is there any way to get a notification event if a Control (or any FrameworkElement) has been scrolled into the viewport and is now visible?
I want to implement something like the Lazy Load Images jQuery Plugin.
I'm trying to embed and then play back a .wav file in a C++/CLI app but all the examples I've seen which use PlaySound are in VB. I can't see how to get froma Stream^ to the LPCSTR which PlaySound requires:
System::IO::Stream^ s = Assembly::GetExecutingAssembly()->GetManifestResourceStream ("Ping.wav");
LPCSTR buf = s->????;
PlaySound(buf, NULL, SND_ASYNC|SND_MEMORY|SND_NOWAIT);
I guess I need some sort of horrible .net memory conversion magic.
I have a ComboBox and a Save button on my Windows Form. When I change the selected value in the ComboBox then click the Save button, the ComboBox validating event fires but the button click is lost. When the selected value is valid this results in the user thinking they have saved the change when in fact they have not.
Why is the button click lost if the ComboBox is valid? Is there a work around?
Hi,
I need to add the OnClick event to asp:DropDownList control, due to the existing events don't satisfy my current needs.
Is it possible to achieve this?
Thank you very much.
I using servlet and Apache ServletFileUpload that provides stream to uploaded image. All I want to do is to store that image to db and also store resized (I using JAI) version to db.
How can I achieve this without saving image to drive. As I understand stream can be read only once. So I need to store whole image in memory? Is it expensive for performance? Or there are another way?
Hello all.
I've done some experimenting, but can't seem to successfully bind one event handler to multiple elements using jQuery. Here's what I've tried:
$('selector1', 'selector2').bind('click', function() {
$('someSelector').removeClass('coolClass');
});
I've tested all my selectors, and they are all valid.
Is what I'm trying to do even possible? If so, can I do it with .live() as well?
Thanks!
