Does anyone has any experience working with the System.ComponentModel.LicenseProviderAttribute framework? More specifically, I am in the process of reviewing our licensing model, and came across this framework. Does anyone has any experience with this? We are looking for the ability to keep track of flags and number of uses of certain features. We would also like to allow our users to generate their own license keys, so some kind of web interface would be needed.... I'm looking into these options: 1. Writing our own custom framework 2. Using the LicenseProviderAttribute framework (if it will be feasible) 3. DeployLX (by XHEO) 4. Any idea you might have...

Is there a way to get notified when the active document changes? So far I've managed to subscribe on the DocumentOpened and the DocumentClosing events, however I did not find any way to know when the active document changed. My addin should be enabled only when the forms designer is viewed, and I would therefore liek to disable it when other documents are viewed. Anyone got any hint for me?

Got 131 at the age of 26.... Too bad it's going to decrease as the year go by... ;P

Hi everyone, I'm trying to find the area of intersection between more than 2 circles. For example, let's say I have a list of 10 circles. I would like to know what's the size of the area they ALL cover (=intersection area). Anyone ever done something like this, or have a suggestion on how to handle this?

I don't care much about the look. I have no problem with the opacity of the window. I've over-ridden the CreateParams, and ORed the WS_EX_TRANSPARENT but this does not give the desired (specified?) results. What I'm trying to do is to have a window passing the mouse clicks to the window beneath it... I also forgot that this works fine, on windows from the same application, if I return HTTRANSPARENT in the WM_NCHITTEST message, but have absolutely no effect on external (other applications) windows... :(

Does anyone know how to do the Ghost window feature, that can be seen at: http://www.absoluteway.com/tweakwindow/window_make_it_ghost.htm[^] ?? This feature allows you to have a truely transparent window, that clicking on it behaves as though it wasn't there and transfer the click to the window bellow it... I've found this reference: "If the layered window has the WS_EX_TRANSPARENT extended window style, the shape of the layered window will be ignored and the mouse events will be passed to the other windows underneath the layered window." from MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn_classy32.asp[^]) But it does not seem to work.... Any suggestion?

Of course I set a breakpoint there. That's in the Debugging101 course. The problem is that when I put a breakpoint in the setSource function, all I see is that the DataMemeber is set okay, but when the DataSource is assigned, its value doesn't change, and the value of DataMember if set to "". I actually managed to solve this specific problem, by calling the setSource function only after the control was added to the form. However, I did encounter the same problem somewhere else in the application, when I tried to add more clocks.

This is a WinForm application, not a web-based one. The data-binding is made after the call to the InitializeComponent() function, in the form's constructor.

I have a an application tha creates several usercontrols during runtime. The usercontrol is called "Clock", and for this matter, it contains a combobox called simply "comboBox1" clocks=new Clock[4]; for (int i=0; i<4; i++) { this.clocks[i]=new Times.Clock(); this.clocks[i].Location = new System.Drawing.Point((i%2)*width, 136+(i/2)*112); this.clocks[i].Name = "clocks"+i; this.clocks[i].Size = new System.Drawing.Size(width, 112); this.clocks[i].TabIndex = 8+i; this.clocks[i].setSource(dsCities); this.Controls.Add(clocks[i]); } the dsCities is a DataSet that has one table. now the problem is with the setSource function: public void setSource(DataSet data) { this.comboBox1.DisplayMember="City"; this.comboBox1.DataSource = data.Tables[0]; this.comboBox1.SelectedIndex=0; } The function works fine for controls that where created on design-time, but doesn't seem to perform the data-binding itself when called from a run-time control. Did anyone ever encounter this behavior? Any help would be welcome.
