• S76 Help with event handling, event being handled twice.

  Let me preface this with a bit of background research I have done and what I am seeing. I have a control that raises a drawing event with some arguments. This control is inherited by another control that I wrote and that inheriting control handles that drawing event. The problem I am having is that every now and again the drawing event is handled twice. I do not mean that the event is raised multiple times, but a specific instance of the event is handled twice by the same event handler, sometimes up to a full half a second after it handled it the first time. This causes and exception to be raised when I try to use the graphics object because it is in some way no longer valid. I have logged and inspected all of my aruments to it in the debu ...Show All

• MylesM Check versioning of client applications

  Hi everyone, I've recently been assigned a project to create a windows form application that will check and report a file version for a variety of client applications. In it's most simple form, if we want the user to check for... say... Macromedia Flash Player version 8, and the user has version 8+, it gives a green checkmark, otherwise it gives the dreaded red 'X'. My questions this... .net 2.0 has some great support in regards to the fileversioninfo class, so checking my versions and such will be easy, but how do I go about searching for such files My approach may be to search for a reg key, find the target path, and use that to point me to the appropriate .exe. Is there an easier, more direct, and/or better approach to this scenar ...Show All

• cexley Is there some serial port selection comtrol?

  Hello, Newbie question: I'm busy writing a class that retrieves all available serial (Com) ports from my computer, showing them in a ListBox and a user can then select one. But before starting re-inventing the wheel I would like to know if allready some kind of control or ActiveX( ) component exists that does this work for me that can be implemented in my application Henk Well, this sort of thing is so trivial that there's not really any 'need' per se, for a control dedicated to it. Here's a snippet of code I use: say cmbPortName is a combo box: 1 cmbPortName.Items.Clear(); 2 foreach ( string s in SerialPort .GetPortNames()) 3 cmbPortName ...Show All

• Hsoros position one form accurately over another resizable form

  My form1 has a button, which when pressed - I need small form 2 to appear exactly under the button. Form1 is resizable, so I guess the button's coordinates will change according to size.

• Roxanne163 Gradient BackColor

  Gradient BackColor. I would like to make a gradient backcolor for controls, like a treeView control, for example... it's posible I tried to override the Paint function. I used a LinearGradientBrush and then draw a fill rectangle, and looks good... but i overlaped the original paint. Suggestions/comments/tips all are wellcome. Thanks Open up Photoshop or Paint Shop Pro, (something similar if you don't have them), make a pretty gradient, and set it as your controls background image. I've used this for my MDI Parent form background. The result is an even gradient. public formMdi ( ) { InitializeComponent ( ); this . Paint += new PaintEventHandler ( PaintC ...Show All

• shyne13 Prevent DataGridView selecting a row - is it possible?

  Hi all, I have a sorted, non-editable DataGridView which contains some cells in each row that are traffic-lighted (ie: they have a different b/g colour depending on value) but when I populate the control the row that was the first one (before sorting) is always highlighted thus wiping out my custom coloured cells. I have tried every combo of colours and highlighting options to try and stop the DGV doing this but can't find a way. Ideally I just want to suppress altogether the DGV control selecting a row when it populates - does anyone know how I can go about this This is driving me mad so I hope someone can help! TIA... Mike I have similar, but still a little bit different problem: in fact, I'd like ...Show All

As in how to create the drop down box and it contents. More details please. Hi, if I understand the question it's similar to something i've done in the past, where I populated a contextmenustrip programmatically. All of the menustrip items have their click events handled by the same method, which determines which item sent the click by querying the Text and Tag properties of the sender (bit basic but you get the idea).  Sorry for the C# btw. void MakeCms() { pronCms = new ContextMenuStri ...Show All
