    - MSP Patches and VS2005 In VS2005 I can create setup msi's for the projects I create. I was wondering is there is a way to make MSP's or, if I'm stuck using Orca. Orca confuses me a bit and after working with it for 3 weeks I still cannot figure out how the MSP's work with it. Thanks, Quilnux Tag: Visual C# General how do I read video memory in C# Visual C#

    - How to implement embedded interface? > I find it hard to understand your problem. A good example is the usage of IEnumerable interface that contains IEnumerator interface. Code Snippet public interface IEnumerable { IEnumerator GetEnumerator (); } public interface IEnumerator { bool MoveNext (); object Current { get ; } void Reset (); } I found one of the solutions to my original question is to create a nested class inside the interface that contains another interface.

    - Is it legal to distribute the Microsoft Application Blocks project for .Net in a Multi Project Template I read the Eula.doc for the Application Blocks for .Net, and it read pretty straight forward that I was allowed to distributre the software as long as the user agress to the Eula.doc that I will also distribute with the templates. I have a free code generator for C# developers (available by october 15, 2007 at www.flyingelephantsoftware.com ) that includes a multi-project template for creating a project solution in the format my code generator uses. I built it including the Microsoft Application Blocks as a project that is included when you create a project from the template. If I need to I can build a wrapper class, but since Microsoft gives this away this should be legal right since I give them full copyright credit and disclaimers as described. I would rather find out here then in a lawsuit if Microsoft thinks I violated something.

    - Event Null Exception sure, my program is layed out with a main gui, a non-form runtime and a configuration form. The main GUI instantiates the runtime, and the runtime instantiates the config form. The delegate and event are declared in the configuration form as follows: public delegate void ConfigurationEdited(); //declare the Save Button Pressed event public event ConfigurationEdited ConfigChanged; I then fire the even when the form closes (FormClosing event). the subscription occurs in the constructor of the runtime as follows: this.LW_Config.ConfigChanged += new Main_Configuration.ConfigurationEdited(ConfigChangedAction); and i get the null exception error when I call the event Tag: Visual C# General how do I read video memory in C# Visual C#

    - Forcing subclasses to implement a virtual method Hello everyone! I'm reading the Head First: Design Patterns book and I've come to the third chapter on the Decorator Pattern. In the book they first have the component class implement a virtual method called GetDescription(), in the decorator class they add an abstract method called GetDescription to force the concrete decorator classes to override the GetDescription() method. However in C# I can't get it to work. If I add the abstract method in the decorator class it hides the one in the component class and when the method is called from the code it's the component's GetDescription method that is called and not the one in the concrete decorators. If I leave the decorator class empty and override the GetDescription method in my concrete decorator classes everything works but everything compiles even if I don't implement the GetDescription method. Any ideas or comments =) Thanks, Marlun Tag: Visual C# General how do I read video memory in C# Visual C#

    - Code Generator for methods I dont think there is a way to do that. I realise I'm thrashing all over what is a personal coding style... But if you type /// in your editor you automatically get: Code Snippet /// <summary> /// /// </summary> Is that good enough Otherwise you could create a code snippet so that after you create your new stub, you can type a few characters and a tab and it gets added automaticaly. Sorry, but that is the best I can think of. Tag: Visual C# General how do I read video memory in C# Visual C#

    - Calling BinaryWriter on sbyte[] I have C# code that creates an sbyte[ ] and J# code that consumes it. I can't use byte[ ] because Java doesn't support unsigned bytes (lame oversight on Sun's part). So my problem is this. BinaryWriter has an overload that takes byte[ ], but not sbyte[ ]. Is there a more efficient way to do the following Code Snippet private static void WriteFile( string outputFile, sbyte [] bytes) { FileStream outputStream = new FileStream (outputFile, FileMode .Create); BinaryWriter binaryWriter = new BinaryWriter (outputStream); foreach ( sbyte element in bytes ) { binaryWriter.Write(element); } binaryWriter.Close(); } Note that this code is on the producer/C# side. (The bytes go to the J# code as well as to a file.) Thanks, Brian Tag: Visual C# General how do I read video memory in C# Visual C#

    - What's the difference between Abstract classes and Interfaces? Good question... interfaces and abstract classes have so much in common it's hard to make a desision at times. Here's a quote from "The Complete Reference C# 2.0" by Herbert Schildt that I like: "When you can fully describe the concept in terms of "what it does" without needing to specify any of "how it does it", then you should use an interface. If you need to include some implementation details, then you will need to represent your concept in an abstract class."

    - C#/MSMQ Issue Thanks for the suggestions, but the only firewall installed is the windows one (on both server and clients) and I've turned that off completely. All anti-virus software has been removed from the server and old client, the new client PC has never had any installed. I'm not using active directory integration, so presume port 389 is irrelevant (Although with no firewalls on it ought not be a problem anyway). Also, I haven't installed the HTTP component for MSMQ, so that's not in use and there is no virtual directory for MSMQ in IIS as a result. Additionally, since the queues do work when I create them manually, that suggests to me that it's not a port issue - the ports work when the queue names are setup manually, so the ports must be open/working At the moment we're working on a test system and all the PC's (server/client) are simply running on their own 100mb LAN - there are no routers involved and no DMZ in between. It's a really simple setup, which is one of the reasons this problem is so concerning. If I enable file sharing etc. it all works fine, and the PC's can ping each other and see each other in network neighbourhood etc. I've also tried putting the two clients in a workgroup (instead of the servers domain), and I get the same symptom - the queues work when the queues are created manually, but not when the C# code creates the queues for me.

    - Custom events for controls in the form designer I have a custom control that I'm trying to draw exclusively in the form designer in Visual C# 2005, but it seems I've run up against a snag. That is, classes derived from System.Windows.Forms.UserControl do not have a MouseWheel event listed in the events dialog. All the other mouse events are there, like MouseClick and MouseDown and so forth, but MouseWheel doesn't appear. UserControl-derived controls do, however, receive mouse wheel messages, and I tested this with the following code: delegate void TestDelegate ( object sender, System.Windows.Forms. MouseEventArgs e); TestDelegate d = delegate ( object sender, System.Windows.Forms. MouseEventArgs e) { MessageBox .Show( "foo" ); }; this .MouseWheel += new MouseEventHandler (d); Is there some way to, rather than adding the event handler manually, enable the MouseWheel event in the form designer Check out http://colinwetherbee.com/data/usercontrol-events.jpg to see the list of events I have.

    - string to hexadecimal string Hi! I have a function i VB.net which converts a string into the ascii hex version of the characters. This functions looks like this in vb.net. Code Snippet Public Function StrToHex( ByVal str As String ) As String Dim stringPos As Integer Dim strTemp As String Dim strTemp2 As String Dim strAnswer As String = String .Empty stringPos = 1 Do While stringPos <= str.Length strTemp = Mid$(str, stringPos, 1) strTemp2 = CStr (Hex(Asc(strTemp))) If Len(strTemp2) = 1 Then strAnswer = strAnswer & "0" & strTemp2 Else strAnswer = strAnswer & strTemp2 End If stringPos = stringPos + 1 Loop StrToHex = strAnswer End Function So if send the string "3310 A" I get the result "333331302041" back. My question is how do I accomplish this in C# Many thanks in advance! Tag: Visual C# General how do I read video memory in C# Visual C#

    - WMF Vector Image Handling hi guys, again, i have a problem handling WMF vector image I have a WMF image which contains text and lines. In Windows Explorer (thumbnail view) the text and lines overlapped to each other, but when i try to open/insert it in Microsoft Office Picture Manager/Microsoft Office, everything is fine. I wonder how Microsoft handle WMF vector images Anyway, i was trying to convert it in another image format (JPG, PNG. just to rasterize it out). But after converting the WMF vector image, still, the problem is the text and lines overlapped. Can you help me with this using C# or VB.NET Thank you in advance!!

    - Enum in generic class Well obviously I use the type, this was just a simple example (just like the code below). I don't think the syntax is "nature". If you use the enumeration outside the class it makes no sense specifying a type argument that is totally irrelevant. It is just confusing. Just to illustrate take this example of a boolean enumeration, why should you give the type "int" (or another type for that matter) all the time Total confusion! Public class A<T> { public enum Bool { True, False, } } A<int>.Bool b = A<int>.False; And about the static class, I'm not talking about the .NET static class (I tried it and it didn't work as I wanted to). I'm talking about how they work in Java. See this sample: public class A<T> { public class B { } public static class C { } } A<int> a = new A<int>(); A<int>.B b = a.new A<int>.B(); A.C c = new A.C(); If A was to be static it'd be the same as a .NET static class, however here the subclass C is static. Static subclasses are still instancible (can be created using new) but has no dependency to its parent class thus no need for a type argument. This is a very important feature which .NET unfortunately lacks. I also miss the feature as shown when createing the B class, the "a.new" meaning you create a class B that belongs to a specific class A.

    - Trouble Checked Locking You're code is not thread-safe: If the first thread is interrupted between the CompareExchange and the creation of the new instance, CONTROLLER is set to CREATED but the instance was not created (because the thread was interrupted by the sheduler). Now a second thread enters the method and thinks that the instance was created but it returns a null-Reference what it should never do. The second fact is, that your version is not as performant as the double checked locking pattern because a CompareExchange need quite more processor-ticks than a simple if statement. The lock in the double checked locking pattern is only done at the beginning (as long as the instance is not created) and it may have a performance-penalty there but in the normal case, the instance is already created and only one "if" has to be executed, so the overage performance is better than the one of your code. EDIT: Further performance penalties are the worse optimizable code because of the volatile declaration and the memory-overhead of the CONTROLLED value.

    - Need to implement AI in TicTacToe Hi, I am developing TicTacToe in which i finished working functionlity where 2 people will play. Now i want to add AI to my game what can be the best algorithm to do that. One more thing any piece of algorithm or any starting code would be very nice. Now just a real question lets say Player selected one box. Now its Computer turn. It has 8 possible moves how would you implement that can you give any idea in algorithm shape or Pseudocode please. I would probably not write code to evaluate each state individually, I'd write a state evaluator that checked for winning moves, blocking moves, and then potential moves based on difficulty. thanks Tag: Visual C# General how do I read video memory in C# Visual C#

    - Structuring up project. If you've got so much code in an event that you find it difficult to navigate the class, I would suggest you create another helper class to perform that logic. The other thing to consider; if you're doing that much work in an event, you might consider doing it in a background process. Taking too much time in an event handler blocks all other events from reaching their handlers--which includes painting and refresh events. If the backlog is too long you end up loosing messages.

I need to search the video bios rom memory at 0xC0000 for certain data. I created an unsafe class and a pointer to the location but I get back all zero's. I read that I need to map physical memory into my user area. Any idea how I do that in C#

Thanks,

You'd need to write a user/kernel mode driver to get direct memory access (DMA) to video memory. You can't do it from inside C# sadly, I suggest you look at the the Windows Driver Development Kit (DDK)

Re: Visual C# General how do I read video memory in C#

Evan Hicks

Right. From what I have discovered since my original post was that this is a permission issue trying to read kernel mode data from a user mode program. Is it possible to do it in C++ A driver is not feasible but I could write a C++ dll and call that.
