  • Getting the Assembly Qualified Name of a class in Visual Studio

    - by Alex Marshall
    Hello, I'm writing a customized reflective library for some specialized custom domain logic, and that library is going to use XML configuration files that will dynamically resolve System.Type objects at runtime. However, when writing the XML configuration files, it's a bit of a pain to write the types because they need to be fully qualified assembly names for Type.GetType() to resolve them. Is there a way to find out the AssemblyQualifiedName of an object in Visual Studio without resorting to writing a program to print them out to a file or standard out or anything like that ?

  • Detecting a stale Mutex

    - by sum1stolemyname
    Is there any technique or tool available to detect this kind of a deadlock during runtime? picture this in a worker thread (one of several, normally 4-6) try WaitForSingleObject(myMutex); DoSTuffThatMightCauseAnException; Except ReleaseMutex(myMutex); end; or more generally is there a design-pattern to avoid these kind of bugs? I coded the above code in the little hous after a longer hacking run

  • Registry Problem

    - by Dominik
    I made a launcher for my game server. (World of Warcraft) I want to get the installpath of the game, browsed by the user. I'm using this code to browse, and get the installpath, then set some other strings from the installpath string, then just strore in my registry key. using System; using System.Drawing; using System.Reflection; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using Microsoft.Win32; using System.IO; using System.Net.NetworkInformation; using System.Diagnostics; using System.Runtime; using System.Runtime.InteropServices; using System.Security; using System.Security.Cryptography; using System.Text; using System.Net; using System.Linq; using System.Net.Sockets; using System.Collections.Generic; using System.Threading; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } string InstallPath, WoWExe, PatchPath; private void Form1_Load(object sender, EventArgs e) { RegistryKey LocalMachineKey_Existence; MessageBox.Show("Browse your install location.", "Select Wow.exe"); OpenFileDialog BrowseInstallPath = new OpenFileDialog(); BrowseInstallPath.Filter = "wow.exe|*.exe"; if (BrowseInstallPath.ShowDialog() == DialogResult.OK) { InstallPath = System.IO.Path.GetDirectoryName(BrowseInstallPath.FileName); WoWExe = InstallPath + "\\wow.exe"; PatchPath = InstallPath + "\\Data\\"; LocalMachineKey_Existence = Registry.LocalMachine.CreateSubKey(@"SOFTWARE\ExistenceWoW"); LocalMachineKey_Existence.SetValue("InstallPathLocation", InstallPath); LocalMachineKey_Existence.SetValue("PatchPathLocation", PatchPath); LocalMachineKey_Existence.SetValue("WoWExeLocation", WoWExe); } } } } The problem is: On some computer, it doesnt stores like it should be. For example, your wow.exe is in C:\ASD\wow.exe, your select it with the browse windows, then the program should store it in the Existence registry key as C:\ASD\Data\ but it stores like this: C:\ASDData , so it forgots a backslash :S Look at this picture: http://img21.imageshack.us/img21/2829/regedita.jpg My program works cool on my PC, and on my friends pc, but on some pc this "bug" comes out :S I have windows 7, with .NEt 3.5 Please help me.

  • ByRef vs ByVal generates errors!?

    - by serhio
    ByRef vs ByVal generates errors!? I had a method that used an Object Function Foo(ByRef bar as CustomObject) as Boolean this method generated errors, because some strange .NET Runtime things changed the bar object, causing its Dispose()al. A lot of time spent to understand the thing(where the ... object is changed), until somebody replaced ByRef by ByVal and object wasn't change anymore when passing to this method... Somebody could explain this, what happens?

  • Associating a modifyable settings file with a class library in C# ?

    - by mishal153
    I have a class library(abc.dll) in which i have used a settings file. An exe (app.exe) references this class library. At runtime if i want to change the values of the settings without having to rebuild the class library/application, what is the best way to approach this problem ? In my current approach the setting values get embeded in the library, and thus i dont see any way to update them without rebuilding the whole thing.

  • Creating a Custom Compound Button Bar

    - by vijay
    I have to create a custom compound button bar control in Android like the one here. To create a button bar like this, I am thinking of extending a LinearLayout and add my buttons to it. The buttons have a black background but with a gradient fill; I am not keen on using PNGs since the color of the buttons can change at runtime. How can I get similar effect in Android? Thanks.

  • importing modules in app engine

    - by tanky
    Ive asked this before, but it seems i wasnt clear/detailed enough and after a week of trying im still struggling so i will try again. i am trying to use, oauth2 and ply on app engine. i have tried copying their directories into my app engine project directory (in the form ply-3.4 or brosner-python-oauth2-82a05f9) and i have tried copying the specific sub directory contained within the aforemention one. (ply or oauth2) i have tried saying import oauth2, from brosner-oauth2_python-82a05f9 import oauth and other variations on the theme, but i still cant get it to work nothing has worked. i have tried including them in app.yaml, but that seemed to create an even bigger error as my entire project wouldnt even run when i tried that. and now i have run out of things to try. the error log i am getting is as follows.

  • .Net 4.0 Memory-Mapped Files verses RDMS Storage

    - by Harry
    I'm interested in people's thoughts comparing storing data in a traditional SQL based Database or utilising a Memory-Mapped File such as the one in the new .Net 4.0 runtime. The data in question would be arrays of simple structures. Obvious pros and cons: SQL Database Pros Adhoc query support SQL Management Tools Schema changes (adding more columns and setting default values) Memory-Mapped Pros Lighter overhead? (this is an assumption on my part) Shareable between process threads Any others? Is it worth it for performance gains?

  • Duplicate conflicting frameworks in cocoa plug-ins

    - by Carmen
    I am currently writing a plug-in framework for my application. I would like to be able to release plugins without having to update my application, and I intend on making the framework available for third party plugins. I am currently running into issues when two plugins ship with identical frameworks. When the plugins are loaded the runtime gets confused because the framework gets loaded twice. What is the best way to mitigate this issue?

  • What if an application needs MSVCR80.dll but I've installed Microsoft Visual Studio 9.0?

    - by user198729
    I'm trying to install this: http://www.coderholic.com/pywebshot-generate-website-thumbnails-using-python/ I've googled a lot,and still can't make it work(gtk runtime has been installed successfully(gtk-demo works),but it still reports can't find MSVCR80.dll,this should be because that I have installed Microsoft Visual Studio 9.0?), each time it reports ImportError: DLL load failed,MSVCR80.dll is not found.. How to make an application that needs MSVCR80.dll work when I've already installed Microsoft Visual Studio 9.0? Or : How to make _gtk.pyd use MSVCR90.dll instead of MSVCR80.dll?

  • How can I progrommatically change the target framework from 4.0 to 3.5 of a project/solution?

    - by scott
    Edit 3: After more googling it looks like you can't have the TargetFrameworkMoniker property in a .NET 3.5 application. So I guess I should be asking a different question. How do I change the Target framework from 4.0 to 3.5? Unfortunately, I can only find stuff on how to go the other way. or better yet how do i progrommatically set the target framework version of a project to something other than 4.0? Original question: I just switched to vs2010. I have an application that uses .net 3.5. It loads plugins which are generated by a different app. The plugins are using .net 4 and there for cannot be loaded. I'm using EnvDTE.Project to create a project and set the settings. I can't find what setting needs to be set for this. Edit 1: I'm generating code for about 50 solutions. When I made the switch from vs2005 to vs2010 the projects in those solutions are defaulting to .NET Framework 4.0. So I need to set the .NET Framework to 3.5 when I am generating the code for these solutions. Edit 2: After a lot of googling I found this. so then I tried this: loProp = vsGetProperty("TargetFrameworkMoniker"); vsSetValue(loProp, ".NETFramework,Version=v3.5"); the definitions for those two methods are below. as far as I can tell they do the same this as project.Properties.Item("TargetFrameworkMoniker").Value = ".NETFramework,Version=v4.0,Profile=Client"; I start getting an Property Unavailable Exception later in the code. When I remove the new lines everything works except the projects target framework is still 4.0. The code generators target framework is 3.5 so I can't use the FrameworkName class like shown in the second example in that link. here is vsGetProperty protected Property vsGetProperty(string aProperty) { bool lbDone = false; int liCount = 0; Property loProp; while (!lbDone && liCount < pMaxRetries) { try { loProp = pProject.Properties.Item(aProperty); lbDone = true; return loProp; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } return null; } and vsSetValue protected void vsSetValue(Property aProperty, string aValue) { bool lbDone = false; int liCount = 0; while (!lbDone && liCount < pMaxRetries) { try { aProperty.Value = aValue; lbDone = true; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } }
