    - Reflection For Class Hi Friends, I’m new to reflection, what I want is… List<FOUnitClassMst> objFOUnitClassMst = new List<FOUnitClassMst>(); FOUnitClassMstBl objFOUnitClassMstBl = new FOUnitClassMstBl(); objFOUnitClassMst = objFOUnitClassMstBl.SelectAll(); sXMLReturnString = objGenSerial.XMLSerialize(objFOUnitClassMst); the above is the code what I have in my current project, I want to implement reflection. I just want to know if this can be done. If this can be done then can any one help me in coding I will pass the class FOUnitClassMst as string, and even FOUnitClassMstBl as string. If needed I will also pass SelectAll() method to it. I want to convert the above string to list of object, and then convert FOUnitClassMstBl to object which is a business layer, I want to execute a method called SelectAll() which resides inside the business layer FOUnitClassMstBl . How can I achieve this Please reply back if any one know the solution for this, I badly need this to be done. Tag: Visual C# General dll decompile Visual C#

    - Navigation from one form to another in Windows applications (C Sharp) There's not a built-in method to do this as far as I know, but you could write it yourself. If you actually want to close the forms as you transfer control, you can call the Close method on the forms, but you will need to take special care that the message loop doesn't end. I'm trying to picture how this program will look, though, and it seems very strange, with forms popping up and closing as you perform tasks. You should seriously try to have a main form to the application if you can, since it will provide a logical point of reference for the user. Perhaps you should consider keeping one form open the entire time, with navigation between various UserControls or Panels. This could behave a bit more like web page transitions without doing crazy stuff having windows closing and opening all over the place. If you already have a lot of work done designing the forms, you could copy that into the UserControls without too much effort. Tag: Visual C# General dll decompile Visual C#

    - Which Namespace contains NullToString ? The method simply doesn't exist in the current contex, but your method should look like the example below. In .NET 2.0 you can use the String.IsNullOrEmpty method: public static bool isEmail( string inputEmail) { if ( inputEmail == null || inputEmail.Lengt == 0 ) { throw new ArgumentNullException( "inputEmail" ); } const string expression = @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" + @"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" + @".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\] )$"; Regex regex = new Regex(strRegex); return regex.IsMatch(inputEmail); } Tag: Visual C# General dll decompile Visual C#

    - Creating Sequental filename. Hi, Store the next number in a file within the directory where the files are written. If someone accidently deletes the file then have your application crash with a rude error message, no if the file is missing then do your idea. If your worried about another thread causing problems then mark the code as a critical section using Thread.BeginCriticalRegion and Thread.EndCriticalRegion. This will ensure the thread completes the task of saving the file. Tag: Visual C# General dll decompile Visual C#

    - Visual Studio 2005 Standard vs Professional Sorry for the delay. Rather than guessing I hunted down a copy of Standard so I could compare it to the higher end versions. I'm comparing it against VS Team Suite but TS doesn't add much over Professional in the area of UI. On the UI side I really don't see any differences beyond what projects and tools are available in the other products. For example unless you're running Team Edition you won't have the performance or code analysis tools. Database support is in the standard edition but you can't create database projects from what I can tell. XML files themselves are supported along with the various views but debugging and whatnot might not work. Macros, snippets, addins, etc are all there as well. Therefore I'd say the biggest factor is whether you want DB and XML support along with code analysis, testing and/or performance tools. If so then you might want to consider moving up to a "higher" version. Otherwise standard might be good for you. From what I vaguely remember (and I could be completely wrong) Standard is designed for the programmer who lies between a hobbyist (Express) and a professional programmer (Professional). Perhaps a student, part-time programmer or someone who just wants to create their own dynamic web site. Michael Taylor - 1/22/07 http://p3net.mvps.org Tag: Visual C# General dll decompile Visual C#

    - Get the installation location of a assembly through c# We are building a project where a template uses a c# assembly. At runtime we want to retrieve the folder where the assemby was installed. with Code Snippet System.Reflection. Assembly .GetExecutingAssembly().Location we only get a location to the current location of the assembly and not the installation path.

To exit the thread I use exitEvent.Set() on any thread which wants to stop the thread. This call is often followed by a thread.Join(); Tag: Visual C# General dll decompile Visual C#

    - I keep getting a hiding error. I'm confused. Warning 2 'WindowsApplication3.generalEnemy.onEnterFrame()' hides inherited member 'WindowsApplication3.SceneObjects.onEnterFrame()'. Use the new keyword if hiding was intended. C:\Documents and Settings\Owner\My Documents\Visual Studio 2005\Projects\WindowsApplication3\WindowsApplication3\generalEnemy.cs 24 21 WindowsApplication3 is a warning I'm getting. Basically I have an abstract superclass SceneObjects, and an abstract subclass Characters, which has an abstract subclass generalEnemy. There is a method called onEnterFrame which is defined as public void in all of those classes. I can't define it as abstract in these classes because some of the subclasses are abstract, and therefore I DON'T want them to implement it. I can't remove onEnterFrame() from my abstract classes because there is a point where I am using polymorphism (overriding) like superclass a = new subclass(). But when I define onEnterFrame() as public in my abstract superclasses, I get an error that my subclasses are trying to "hide" the superclasses's method. It tells me to "use the the new keyword" if hiding was intended. Can someone explain how the new keyword is pertinent, and what exactly hiding is Where I'm from, overriding a superclasses's method is called inheritance.

    - COM object interfereing with a CheckBoxList? Basically to answer it myself, it turns out I had created a new CheckBoxList along the way for no reason. When I ran that code the other box stayed, but I guess I hadn't told my new'd variable anything, so it got the information as was valid, but simply didn't show up. So I the answer is, if you add something via the designer... don't add it again via a new. Tag: Visual C# General dll decompile Visual C#

    - Explicit Conversion of Base Class to Derived Class Fanon wrote: I did a search on the subject, and the answer I found said that converting a base class to a derived class is not possible. I find this answer to be unsatisfactory, and I wish to make sure that it is indeed the correct answer. I am writing some code (obviously), and in my code, I have a base class and an inherited class of that base class. There are times I wish to convert the base class to the inherited class. According to section 13.2.3 of the C# specification, this is possible: "From any class-type S to any class-type T , provided S is a base class of T ." There's also evidence that in the .NET Framework that it's possible (converting WebRequest to HttpWebRequest and Control to TextBox ). So why is it I get a runtime error of InvalidCastException when I attempt to explicitly cast an instance of my base class to an instance of a derived class of that base class You can't convert an instance of a base class to a derived class without some sort of conversion operator. If you have a instance of a derived class stored as a base class variable you can cast as a derived class. For example: Code Snippet Base base = new Derived(); Derived derived = base as Derived; Tag: Visual C# General dll decompile Visual C#

    - CallBackOnCollectedDelegate C# Hi.... Is your App getting crashed when the error occurs I also had the similar problem of " Callback on Collected Delegate" I couldn't find a permanent solution for my prob yet. But for the time being.... go to menu item Debug -> Exceptions -> Managed Debugging Assistans. and Turn Off the CheckBox. (it was suggested for me by an MVP, nobugs! ) This will avoid the error temporarily..... but this is not the absolute solution. I also reported the prob at Product Feedback, but there's no solution yet. If you find a good one, pls let me know, o.k! Thank you, Tag: Visual C# General dll decompile Visual C#

    - this.Invoke OR Control.Invoke ?? If you copy and paste into word first and then here you will keep colors and formatting. There should only be minor difference between invoking a delegate on the form compared to a control on the form. The reference to an control (or form) should just be to determine what the UI thread is and the Invoke() method ensures the code is executed in that thread. this.Invoke() should be as fast as this.txtAction.Invoke() as I assume they are both known by compile time meaning they will both be known references and accessed equally.

    - Delegates and events Hi Sammy, There are two ways I can think of through which your problem can be solved. 1) Use this.MdiParent.MdiChildren property which is Form[] array from any of the child form. Iterate through that array and find the other form you want may be by matching the Name property. And call some public method on it which causes it to refresh it's data. This way you tightly couple the forms. 2) Second way is create an event in the parent form and a public function which causes to raise that event. Now, if Form2 has data to refresh, and Form1 changes data, Form2 subscribes to the parent's event and Form1 after changing data calls the public method to cause the event to raise. So, Form2 updates data in the Form2_ParentEvent function or whatever function it used to subscribe to the parent's event. Tag: Visual C# General dll decompile Visual C#

we have a small issue with a dll written by one of our ex-programmers.

he left without giving the source code, he did gave us the dll. and the application isn't working.

is there a way to decompile that dll

thanks

You have a pretty bad issue with this programmer. This might be a great time to change your business policies.

Search google, lot's of them exists.

Re: Visual C# General dll decompile

IsshouFuuraibou

if the DLL is in .net, you could get the IL decompilation of the library, but other than that, it is extremely hard to reverse engineer a library, and you can't be certain that you returned to the code that you originally had.

You can use Lutz Roeder's .NET Reflector. Take it from here:
