• Visual Studio Express Editions Error when converting Visual Studio 2003 projects to C# Express 2005

  I'm getting the following error when I attempt to load a project that was created with Visual Studio 2003 in Visual C# 2005 Express Edition. I've checked all of the files in my solution to ensure that none are read-only. Does anyone know what's causing this error Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Thanks. I have noticed the same problem with Visual C++ express. Any feedback would be welcome. Thanks ...Show All

• Windows Forms How: Layout Managers in .Net like Java

  Hi, How to achieve effect of LayoutManagers like java has Grid, Flow, Border etc layouts in .Net The case is : I am creating the form runtime and adding controls on run-time so at that time its very hactic to manipulate about other control's sizes, positions etc so there must be easy way to do such things like what Java LayoutManagers allow without worring the actual positions in pixels. It allows me to add, insert etc operation without knowing other control's pixel positions. I should be allowed to insert some control after some other control by giving index or name directly which is not possible in Forms. Any pointers please Microsoft i ...Show All

• Architecture Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project. Then maybe I will write mapper classes for bussiness classes to map DB tables or using an O/RM tool or an ODBMS . Think that this project is big one and it has long deadline. You will develop it 2 or 3 years. Requirements will be changed. To develop this project with OOP designs and n-Tier application design is good idea. But I am asking myself this question "Why am I choosing this long way ". I think the advantages of OOP are re-usable and flexible (when there is a new requirement). OOP makes less code behind user-interface. But I dont un ...Show All

• Visual Studio I don't know what you're telling me.

  Well, hello there. Hello . I'd like to talk to you today about something rather close to my own heart, the kind of thing that doesn't pop-up real often-like when you're gathered 'round the water cooler in your office. The kind of thing that might be shyly batted around behind closed doors, if you pick up what I'm puttin' down. The kind of thing that you wouldn't find yourself laughing about at a cocktail party over a few dry martinis. Now, maybe I'm not in the right place here, maybe I'm not talking to the right folks. Maybe. I'll say this though: my life is short, and every chance taken is a sharp breath of cold air before the sunrise on a ...Show All

  Hi all, I am working on a Windows Forms custom control now and I would like to place my control right on the Toolbox window after installation, however, this seems to be a problem now.

  I am writing an application to control a couple of devices that I have.  All of the control code is written so I am developing the UI.  One of the forms that I have put together has eight groupboxes.  Two of the groupboxes are on their own.  One of these groupboxes contains six buttons.  Each of these buttons corresponds to one of the remaining six groupboxes.  Clicking on one of these buttons causes the third groupbox to appear.  These six groupboxes are all the same size and are positioned one on top of one another.  I am running into a couple of problems with this form related to the groupboxe ...Show All

• Visual C# Printing the contents of a RichTextBox

  I am trying to figure out how to print the contents of a RichTextBox that contains formatted text and pictures using managed code only. It was easy in C++, just redirect the dc, but I am at a loss here. I thought the easiest way would be to generate a series of bitmaps for the pages. I know how to do a screen capture, but not all of the contents are visible if the document is long. I am hoping I am missing something obvious. Any help would be greatly appreciated. Look at this and this ! .. maybe you are " missing something obvious" Cheers! ...Show All
