• stuart54321 Defining custom functions for code snippets

  Code snippets allow you to use functions to do some processing on the data that gets inserted. AFAIK, currently there are only three functions available for C# (for instance SimpleTypeName). Would it be possible in any way to expand this set of functions For instance, I'm looking for a CamelCase function to be able to create a code sinppet that outputs code such as this: private int _myNumber; public int MyNumber { get { return _myNumber }; } Because of this naming convention, I only want to specify the type and name, and not as in the current propg code snippet, also specify the fieldname. Any ideas Why is functionality necessary Is there a reason why supplying another snippet, built to your own speci ...Show All

• JustinParkes Inaccurate/Wrong calculations

  Hi, I working on a fairly large project in C#, combining numerous components such as SQL and DirectX. We all, however, seem to have come across a severe problem! We can't do basic arithmetic! For example, in VS.NET 2003, I need to subtract two UTC style time values - eg 11565456546546.1342345566 etc. double large_val1, large_val2; ... double difference = large_val1 - large_val2; Instead of the result I expect (and indeed the result shown in the Watch window during debug for large_val1 - large_val2), I get a servely rounded value instead - that is entirely useless!! Help!! I can do this in a standard command line / console application and everything works fine - why should there be any difference ! I have tried decimal, ...Show All

• Scheinka Capturing the up/down arrow key in a child form

  Hi, Recently, I was trying to capture the UP arrow key from my window forms application. I was able to capture the key in the parent form but once i open a child form, I would not be able to capture all the arrow keys but the rest of the keys like 'a', 'b','+' and etc are ok. I have searched the web but did not find any solution. Does anyone know how to overcome this problem Thank you. Soh GavH is correct. You should avoid using KeyPress or KeyDown event because will produce some Debuging problems and will not catch some special keys. ProcessCmdKey is a right way to do it. soh99, What is on your form Most controlls capture the various keys as they are used for example moving the cur ...Show All

• KIWIDOGGIE Naming conventions

  Hello everyone, As projects get larger it becomes harder and harder to remember all of the variable names and types. I'm wondering if there is some form of naming convention out there for the C# programming language... What I'm really after are 'conventions' for variable nameing... An example is 'append List to all of your objects of type list, name all your global variables tith a '_' prepended, etc. Does such a document already exist Thanks Chris oh yes, we have had rather a good heated discussion about it too just recently - if only I could locate that thread but here is one with the doc: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=818003&SiteID=1 Let me recommend the following book for y ...Show All

• juanraul TreeNode Tag problem

  I am having some problems with a TreeView control, the thing is that I have populated a tree with nodes an attached different objects to the different nodes using the Tag property. My problem is that when the user clicks the nodes, different things is supposed to happen depending on which type of node is clicked. How can I determine which object is embedded in the nodes Tag when the select event is triggered Regards, Peter Larsson! You could implement a interface for all your tag objects, and then in your click event handler you cast the tag object to that interface and call a method on the interface and let the different implementations of the tag objects do what needs to be done.

• Dotnet007 ControlTemplate best practices (after Cheng R. :-)

  Hi, I would like to discuss the usage of Xaml elements from code. MSFT people say it is discouraged, though it is impossible to avoid it in complex solutions. For example, lets consider Toolbar class. Toolbar is not a complex control, however it uses the names from its template from code ( "PART_ToolBarOverflowPanel", "PART_ToolBarPanel" ). And I believe many other controls do the same. There is even an internal class StyleHelper that partially serves as "names locator". So how can we, ordinary people, be forced to stop using template names from code if it is barely possible in the simplest cases So what's wrong with this approach Will it really be impossible to split UI and logic entirely Or we just a ...Show All
