It should be under the logon tab. www.troschuetz.de Using C# dll in vb6 Zapss6-Oct-04 0:27 Zapss 6-Oct-04 0:27  Hello Re: Using C# dll in vb6 Stefan Troschuetz6-Oct-04 1:10 Stefan Troschuetz 6-Oct-04 1:10  Do you have a specific question or just wanted to say hello www.troschuetz.de Re: Using C# dll in vb6 Steve Maier6-Oct-04 6:44 Steve Maier 6-Oct-04 6:44  One method of using C# class or a C# dll is to wrap the C# code as a COM object that you can then use in another language. Here is a link to an article on that. http://codeproject.com/csharp/COM_Object_in_C_.asp[^] Steve Maier, MCSD MCAD Height of Font sachinkalse5-Oct-04 22:32 sachinkalse 5-Oct-04 22:32  Font.GetHeight Method and Font.Height Property are being described in almost identical words in MSDN. If I test both the font size = 11 The GetHeight return 14.66667 and Height Property returns 15Font. What is the difference between two values? please guide Re: Height of Font Christian Wikander5-Oct-04 22:45 Christian Wikander 5-Oct-04 22:45  The difference is described in the documentation for Font.Height in MSDN. GetHeight is returning a float and Height is an int. GetHeight is returning the exact height and Height is GetHeight rounded upwards. Re: Height of Font sachinkalse6-Oct-04 0:17 sachinkalse 6-Oct-04 0:17  thanks for the reply, but i actually had deleted this question when i realised the difference, i don't know how come it still remains there in the forum. regards MDI Child form starts off without titlebar widgets benjymous5-Oct-04 22:26 benjymous 5-Oct-04 22:26  I've noticed a strange bug in my application (C#.Net using the express 2005 beta) I've currently got it set to open new child windows maximized, and I get the normal child minimize/restore/close/etc buttons appear on the parent's menu bar However, if I restore the child window, it's a bit hit or miss as to whether the child window gets widgets in its title bar See screenshot[^] - the King Tut image window doesn't have widgets, but the other two windows do. I've found that sometimes resizing the child window a bit makes the widgets suddenly appear. What am I doing wrong? (or is this a Whidbey bug?) -- Help me! I'm turning into a grapefruit!

Make a component appear on the form at design time Christian Wikander5-Oct-04 22:18 Christian Wikander 5-Oct-04 22:18  I'm trying to make a component who's function can best be described as similar to the MainMenu component in VS.NET. The component should be able to add controls to the parent form at design time. Via code in the component, I can create the new control and add it to the same container as the component, thus making it visible in the properties window of the form (via the combobox in the properties window), but I can't seem to figure out how to make the control visible on the form. How can this be done? Re: Make a component appear on the form at design time Hadi Fakhreddine6-Oct-04 0:06 Hadi Fakhreddine 6-Oct-04 0:06  If your component is a UserControl then you should have no problem seeing it on the form when you drop it from the toolbox. It acts as any other .NET built-in component. The component should be in a seperate project and should be a UserControl type. Re: Make a component appear on the form at design time Christian Wikander6-Oct-04 0:36 Christian Wikander 6-Oct-04 0:36  The UserControl does not look the same as the MainMenu. As for the MainMenu the main component is the one that sits in the yellow field below the actual form. From that, several controls on the form are created, one for every MenuItem. I want to make a component (inherit from System.ComponentModel.Component) and by using code in the component I want to create several controls on the actual form at design time. Just like the MainMenu or the toolbar of VS 2005. The reason for this is that I want to manage several controls from one location, the component. how to handle a mass of lables in C#? momer5-Oct-04 22:17 momer 5-Oct-04 22:17  The problem is: I want to use a for control sentence to control 16 lables,each time I want to change one lable's Text property.Suppose the 16 lables are lable1,lable2,lable3,...,lable16.

Releasing unmanaged memory plessing5-Oct-04 22:15 plessing 5-Oct-04 22:15  Hi I have a C# application which makes use of an unmanaged C++ DLL. Some of the DLL calls return pointers to dynamically allocated memory. My question is this : can I release that memory with C# (and how) or do I have to release it in the context of the DLL - that is, call C++'s delete on the pointer) ? I'd appreciate any kind of help with this. thanks, p. How to set invisible column of List View yu-yu5-Oct-04 22:12 yu-yu 5-Oct-04 22:12  Hello, Do you know how to set invisible column. For example, There is a list view class, this has the following 4 columns. user, password, class, data And, I made other column, named check. I would like to hide this. If you have some ideas, please tell me. cheers, yu-yu Re: How to set invisible column of List View Christian Wikander5-Oct-04 22:20 Christian Wikander 5-Oct-04 22:20  You can set the width of the column to 0. But be aware that if you allow the user to change the width of the columns it's possible to make your 'hidden' column visible. Re: How to set invisible column of List View Anonymous6-Oct-04 3:31 Anonymous 6-Oct-04 3:31  Another approach: Keep that "column" out of the listbox/listview. a) Data Collection with 5 columns b) VISIBLE list with 4 columns c) If changes occur in the visible list (events), update the data collection accordingly. If you need data from the 5th column, retrieve it directly from your "in-memory"-data-collection.
