• Windows Forms GUI Drawing

  Hi Guys, Ok, This is probably going to sound like a stupid question, so please excuse my noobiness...... I have a form, with various sets of data in it, now the thing is, I would like to create a line to seperate the look of the data. How the hell do I just draw a graphical line, that does nothing, but be a line. Sorry for the noob question, but i`m only just starting out in VB ( My first programming language ) The rest of the system seems fine, and I have managed to do some quite complex things, but the basic line draw, is beyond me, and my head is now hurting. Thanks in advance guys... Max Phizz, Many thanks for that, did what you s ...Show All

• Windows Forms MouseDown in Client Area of MDI never fires?

  Very strange; it never fires. Oddly (to me), if I assign a ContextMenu to the MDI form, it comes up fine with a right-click in the form, but it also comes up with a right-click on a MDI child form, unless the child has its own context menu. The problem I have is I create a context menu when the user clicks in a certain area of the MDI form; when that happens, the static MDI ContextMenu is also displayed. If I can detect the MouseDown (or Up) on the MDI form (esp. client area), then I can create all context menus on the fly. ---Mike The problem here is the WM_CONTEXTMENU message.  If a control ...Show All

• Windows Forms Imitate DataGridViewTextBox behaviour to add rows

  I'm currently developing custom datagridviewcells and facing the following problem: When entering the last row in a databound datagridview (the "new row") and focusing a DataGridViewTextBoxCell the editmode is initialized and the grid waits for input. After typing the first char, a new row is created and the row is bound to that row. I need to imitate this behaviour WITHOUT typing. I developed a custom datagridviewcell with its own datagridvieweditingcontrol but which method / property is responsible for adding the new row I tried to call Me .DataGridView.NotifyCurrentCellDirty( True ) but it doesn't work ...Show All

• .NET Development System.Media.SoundPlayer WebForms issue & workarounds + a strange noise problem

  Hopefully this is the right place for this, although what I am experiencing happened with C# and a webform it seems like a CLR issue more than anything else to me. While testing out sounds in a C# WebForm, I found that trying to play a sound via SoundPlayer using a URL would not work. It would throw a web security exception (I forget the exact name of the exception) even though the URL it was told to retrieve the sound from was the same location as the webform. It seems like a bug that the SoundPlayer couldn't access this data, but I was able to work around it by using the following code to get a stream of data from the same place t ...Show All

• Visual C++ Dynamic add controls to a dialog frame.

  Is there a relative easy way to dynamic add controls to a dialog frame For example, in JAVA, you can put an array of comboboxes in a form and initially set the array size to one, and them add more when you need. Is there any thing like this in VC++ Thanks in advance. jpx wrote: For example, in JAVA, you can put an array of comboboxes in a form and initially set the array size to one, and them add more when you need. You could use a vector to hold the controls. e.g. std::vector<CWnd*> ev; void CDialogTestDlg::OnButton1() { CWnd* edit; int t = 0; for(int j= 0; j < 3; j++ ...Show All

• .NET Development windows service process flow

  I have created a windows service in c# and it works fine but i have a question in my mind: In my service constructor i call a method to initialiaze all variables which are defined from app.config. and in OnTimer method, service does what it should. So at each interval it starts its job. I was thinking about process flow of my service application and i thought it should work like this : when i start Service i am actually making one instance of the service and variables will be initialized. Then at each interval, service uses those initialized variables. When service is stopped and started again, another instance of service will be made and al ...Show All

• Visual C# A beautiful language ruined by generics

  I've read all your arguments. I see good points of each side. Thank you for letting me enjoy this article. It seems the question is for C#'s code readability v.s. code reusability. As a solution developer I prefer not to use generic or template because my problem domain resides in a specific classes or types. However if I need to maintain or to develop a library, I probabily look into generic stuff. Hmm... ...Show All

• Visual Basic Launch URL from Windows Service

  Hi all, Anyone knows how I can launch the browser from a Windows service I tried with S ystem.Diagnostics.Process.Start(URL), but it is not working. I just took a quick look and I didn't see anything like such a switch. There are lots of ways to go about it with the API such as using startproc and making it a detached process. I can't remember if there are window size parameters or not. Or you may be able to issue a sndmsg to it ...BUT most of the these techniques require some systems knowledge and programming finese. I don't think I'd try them right off the bat. ...Show All

• Visual Studio 2008 (Pre-release) How to set the size of the Thumb?

  I have ListView within a GridView. The datacontext for the ListView are 1,000 items, for example. At the startup only load 100 items are loaded. When the user scrolls to end of the ListView, a event will be thrown to load the next set of items, and so on. </br> Unfortunately the Thumb of the ScrollBar shows only the size for the current amount of items.
