• .NET Development XMLSerializer Bug?

  Hello all, I am attempting to use the XMLSerializer in a rather unique way, and getting some unexpected results.  I am wondering (1) why I'm encountering this, (2) if others have seen this, and (3) if there are any official fixes in work. Here's the code: -------------------------------- private int x; public int X {     get { return x 0; }     set { x = value; } } [System.Xml.Serialization.XmlIgnoreAttribute] public bool XSpecified {     get { return x.HasValue; } } -------------------------------- When I try to serialize the class that contains ...Show All

• Visual Studio Fixed diagram layout

  When I'm using my own DSL I noticed that I spend lot's of time with layout related stuff. Putting the shapes in the right places, making sure lines don't cross, etc. etc. My opinion is that I shouldn't spend time on this. I like the approach which is used in the domain model designer of the DSL tools itself where the layout is fixed. Is it possible in some way to add this kind of behavior to my own DSL Thanks for your help, Gerben [Avanade] Gerben, You might try the following approach: using ( this .TransactionManager.BeginTransaction("Custom: Layout Diagram")) { this .AutoLay ...Show All

• Windows Forms Why is ClipRectangle always 1px too wide and high?

  As already in the subject. If you have a Graphics objects of a control and check the ClipRectangle property it matches the size of the control, however if you try to draw a border:             Brush b = new SolidBrush(SystemColors.ControlDark);             Pen p = new Pen(b, 1);             e.Graphics.DrawRectangle(p, e.ClipRectangle);   the bottom and right lines can't be seen because they're 1px too wide.

• Visual Studio Visual Studio Add in help

  I need to write a VS add in that will do the following: 1) add to the context menu when the user right clicks on a Referance that is added to the project 2) will need to be able to modify the project file based on menu items clicked. 3) Detect if a property is changed in the Property Explorer for one of the Referenced files.

• Visual C# windows forms getting controls

  I'm pretty new to C#,  so I'm programming some sampleapps to get some experience. Currently I'm programming a Sudoko puzzle solver. I have 81 textboxes called txt11 .. txt99 the textboxname includes information of its location within the sudoko matrix. the first 1 is specifing a row, while the second 1 specifies the column. With a double nested for loop I would like to get all the values from the textboxes and put these values in a two dimensional array. I thought I should be able to get the textboxes by constructing their names.. and doing something like an Evaluate like in Javascript. Hmm well that's not the case.. Can some ...Show All

• Visual Studio Express Editions Resources for Beginners

  Good day fellow developers, Being a 4GL database developer for over twenty years, I've now decided to break into the Web development world and have a simple question maybe you can help with. I'm running Visual Web Devloper and SQL Express setup, and am very familier with SQL 7.0. I would like to know what resources would be the best starting point to begin to understand HTML, XML, ASP, and .NET logic. Having read the associated manual "Build a database NOW", a few things like the editor, and functionality of the objects are confusing. You can't seem to "highlight and move" objects in the editor, and trying to understand t ...Show All

• Visual Studio Team System mstest with custom test type and metadata(vsmdi) file?

  I'm trying to use mstest.exe to run a test from the commandline. The test was created as a custom test type that I have created via the extensibility SDK. I've done a lot of investigation and here's the results: 1) inside VS I can run the custom test fine. 2) I can run the custom test fine using the /testcontainer: option of mstest.exe. 3) I can run a generic test using the same vsmdi file with mstest.exe. 4) trying to run the custom test type with the vsmdi fails with an "Test <foo> cannot be found" error. I ran scenarios 3 and 4 (only difference being generic test vs. my custom test) under cordbg. Here's t ...Show All
