• Visual Studio Express Editions Structures, Arrays, Classes... what to use in my case? I'm confused :(

  Greetings! I've advanced a whole LOT on my program now, I got the full client part done in just 3 days o_o... anyhow! as I'm converting my old PureBASIC app to C#, I really loved the way it would use "Structures" to hold "Array data". For example, in PB I could do... Structure Info User.s ; String Warnings.l ; Long integer EndStructure Dim UserInfo.Info(2000) And for accessing/writing I could do, for example: UserInfo(8)\User="John" Basically an array with multiple data types inside. Now I've been searching around the net and found a "dilemma" about classes vs structures... I don't care much if those are in the "heap" (something I don't even understand yet :P I'm self-taught) or o ...Show All

• SQL Server How I Imported my SQL Database Entities into my SQL Compact Database

  Hello: I am still working on my project, but figured I would share my findings with the community, on how I imported my SQL Server database tables into a new SQL Compact Edition database. Unfortunately, I haven't figured a workaround to the IDENTITY_INSERT issue, but other than that, I will proceed. 1) I downloaded and played with the tool presented in the article " Generate SQL Insert statements for your SQL Server 2000 Database " I made the following modifications . (my modification can be found here ) a) Disable scripting dependencies b) Add a filter for objects to script c) Prompt for each table from which to export data 2) From the scripts output by this tool, I had to (which I may integrate into the tool later. ...Show All

• Visual C# New C# Keyword - retry?

  I believe that C# could benefit from extending try-throw with retry keyword. Simple example of this would be: try { PerfomAction(); } catch(Exception ex) { DialogResult dr = MessageBox(ex.Message, "Error", MessageBoxButtons.AbortRetryIgnore, MessageBoxIcon.Question); if(DialogResult.Retry==dr) retry; // Jumps to the begining of try block } IMHO: This makes for cleaner-looking and less bug-prone code than the alternatives with goto or loops. I dont think so... On the case that what in the "if()" is meet again and again the program gonna do endless loop. So, it seems to be somewhat dangerous. Otherwise, programmers can do this optionally using functi ...Show All

• .NET Development Editing and Deleting nodes in VB

  Howdy, I'm working with a program using an XML file, and I'm trying to delete and edit nodes and attributes (well, delete nodes and edit attributes). I've looked around a fair bit, including through these forums, and simply can't find any good easy-to-use tutorial or documentation on this sort of thing. Does anyone know how I can edit or delete nodes using VB.NET, or any tutorials Any languages is pretty much fine (I can sort of try to translate it, but I would really prefer something about VB.net, if anyone has something of the sort). I've looked all over, and can't really find anything that I'm looking for. Thanks so much! Anything really is greatly appreciated. Thanks again! -Robert Good job Mark. Couple notes.

• SQL Server Connection denied. Please help

  Hello, everyone. I'm new in Reporting Services 2005. I encountered a confused connection problem. I'm running a named instance (called 'sql05') of SQL Server 2005 Standard Edition(a SQL Server 2000 instance as my default) on my Windows XP Professional machine. I log in Windows XP as a member of Administrators group. When I came into SQL Server Management Studio and connect to my local reporting server using Windows Authentication, the report server denied my connection request 'actively'. The service is running but it denied my connection. But when I use the same method to connect to my database engine and Analysis Services in Management Studio, no problem has happened. Does anyone have similar experiences I appreciate for any help. Thank ...Show All

• Visual Studio Detect when a value changes

  What I try to achieve is: I have 2 breakpoints and between those 2 break points, I have a variable whose value is changed. I want to detect in which line the value changes. I think in vb6, you were able to put a watch with condition and whenever that value changed the debugger stop in that line. Ex: 1 dim x = 0 2 ... 3 … 4 … 5 … 6 … 7 x =55 8 … 9 … 10 … 11 … 12 … So I have a breakpoint at line 2 and after this point I want to capture in which line x value is changed. It should return line number 7. How can I do this in Visual Studio 2003(VB/ASP.net). Thank you very much in advance. Selim What you need is a data breakpoint. Unfortunately, they only work when debugging unmana ...Show All

• .NET Development Reflecting Child Objects

  I am getting a MissingMethodException when trying to use reflection to get data from a child object. What am I missing Here are my classes: public class classA { public classB B = new classB (); } public class classB { public int x = 10; } And the code: classA a = new classA (); object ret = a.GetType().InvokeMember( "B.x" , BindingFlags .GetProperty | BindingFlags .GetField, null , a, null ); The name of the field is "x", you don't need to put a B. in front of it. B is known since you are doing InvokeMember on the type of B. object ret = a.GetType().InvokeMember( "x" , BindingFlags .GetProperty | BindingFlags .GetField ...Show All

• .NET Development How to: Make generic collection from derived class

  OK, this was hard to explain on a short title. Sorry. I have an abstract class (MustInherit) named Base, and a generic collection class named ColBase which can only take Base and derived classes as it's type. I also have an indefinite number of classes that inherit Base. I want to make a method on Base that returns a ColBase(of Base), but instead of ColBase(of Base) use the derived class. So if I have a class named Inherited, when I call Inherited.GetColBase it returns a ColBase(of Inherited) and not a ColBase(of Base). Do you know if this is possible, and if so, how to do it Thanks a lot, Joaquin Raya Sorry for the late reply. If this is still an issue - can you share your source so that I ...Show All
