But as I tried to jump into the fire ( and its hot ) i found nothing but frustration. Hence, I have improved on my "google" searching abilites and might add found "never before patience." Says my wife. Any way. Too bad for all of the very nice people that have put up with my "trey" annoying posts asking horribly bad questions. Why You may ask Well because I am not giving it up thats why. I have this need to learn. Its a very bad habit know. So I am starting over ...Show All

• Visual C# Do you know what's the different between "equals" and "=="

  Hi, Do you know what's the different between "equals" and "==" No, you *can* use == on string variables, as System.String overrides == operator (note that both sides must be string variables, otherwise System.Object's == operator is called, which does a reference comparison)   string s1="Test"; string s2="Tes"; s2+="t"; /*prevent string interning*/ Console.WriteLine((s1==s2)) //prints True   ...Show All

• Windows Forms UserControl expose datagridview columns collection in design time

  Hello, I have a user control containing a toolbar and a datagridview, I want to expose the datasource (all ok) and the columns collection (not so ok). I get a basic columns editor, complete different from the one you would expect, I end up having text columns only and I can't add any new columns. Anybody any idea, I just spend 2 hours googling, msning, ... Thanks, Peter The DataGridView column editor is a private designer, so there isn't any way to get it on your custom UserControl.

• Windows Forms Displaying Int values as Hex in datagridview

  Hi all, desperation has forced me to my first post! I am writing a network analyzer and need the option to display my int variables as Hex values for a number of databound datagridviews, (a la) debugger. I can ToString("X") but it would mean having a string equivalent for all my ints! As I am binding to bindinglist of a managed class.(bindinglist<class^>) C++ Started using .Net only 4 months ago so am hoping that my lack of knowledge is the problem to finding an easy solution. While I am asking, how can I force zero filling on conversion to Hex, should ToString("4X") give me 4 Hex Digits. It would ...Show All

• Visual Studio 2008 (Pre-release) foreach or yield on a 'stream' instead of an IList?

  I'm a recent exile from Java land and would like to know the following for C# (2.0 ... can't use LINQ in production yet :( ): What is the best way to not just iterate through a list, but keep track of new entries to it and 'process' those as wel.  In other words, I would like to do something like this: foreach(Data d in myList) Console.WriteLine(d.somevalue); The above line will just go through the list and display the 'somevalue' attribute of the list.  I want the foreach loop to keep 'listening' to 'myList' and each time a new value is added, WriteLine that as well. The reason I"m posting this in the LINQ forum is because I wo ...Show All

• Visual Studio Trouble with Project Template for Package (ProvideProjectFactory)

  I've created a new project type like the sample in Archives\CS_Samples\Project. But I'm confused on how to control the template that is added for the project. I've exported a template from a different project, unzipped the contents and placed them into the Templates\Project folder. It compiles and runs, but there are two templates that show up in New Project, one that is named the same as the .vstemplate file and a second based on the csproj file that is part of the real template. How do I get the second item to disappear I've tried just inserting the zip file that is generated by the export template wizard into the folder, but it does ...Show All

• .NET Development request.BeginGetRequestStream with FTP in ACTIVE mode problem.

  Hi, i'm making an asynchronous upload function. When using .usepassive = true all is good, i can transfer and catch pretty much every exception thrown at it.
