• Visual C# question about assembly loading

  I'm dynamically loading an assembly at runtime and trying to use it but I'm running across something strange. Assembly A contains a common interface type Assembly B contains an executable that loads a type from Assembly C, and contains a reference to the common interface. Assembly C contains a type that inherits from a class that implements the common interface found in Assembly A. now. at runtime I load up the an assembly which is specified in the app config, and recursively walk its references until I've loaded every reference possible from Assembly C. In that walk I load all loadable assemblies, then get all the types in that assembly and cache that data. After recursively walking all the dependencies of th ...Show All

• Visual Studio Team System Debugging and Tracing

  Hi, Ok here's a scenario, we are using VS team System and developing a product in C#.Net. We have created our own architecture and It is common to various products so it is developed as a separate solution. We are preparing daily builds for the architecture and storing in a network location. All the references are thus made from GAC and it is updated frquently. The problem is that while working on a specific solution (lets call it SP) (this one is separate from the architecuture framework solution lets call it A) for a product we have references from the GAC. Is there any possibility to debug and trace the architecture from within the solution SP. In other words we want the trace to go to architecture as if it is included in the same so ...Show All

• Windows Forms Dynamic Help!

  Another help related question: I am using HelpProvider and I see dynamic help functionality for my controls. My question is how can I make that happen at run-time. That is if the users are able to see the dynamic help while running my application, that would be too good, instead of them pressing F1 whenever a control gets focus. Thanks for your time! The key is to catch the control's Enter event. Here's some sample code: using System; using System.Windows.Forms; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); InstallDynamicHelp(this); } private void InstallDynamicHelp(Control container) { foreach (Control ctl in container.Controls ...Show All

• .NET Development Will assembly be functional after sending it with WCF?

  My question extends from the second part of Zhisheng Huang's reply in this post: http://forums.microsoft.com/MSDN/showpost.aspx postid=1205641&siteid=1 I am trying to create a WCF service, that should enable the user to create his own plugins, install them on the server at runtime and make them available to the clients. So basically the server loads plugins that implements an IModule interface with Assembly.LoadFrom and creates instances with Activator.CreateInterface. These instances are then returned to clients. The modules implement 4 methods that I want to execute on the clients. But when the client tries to deserialize an actual module received, I get the following FileNotFoundException: "Could not load ...Show All

• Microsoft ISV Community Center Forums Limit Macro to current workbook

  I have two Excel files with two macros in each one. One Macro Protects the all Worksheets and the other one Unprotects them. The difference between files is that one needs a password protection and other one doesn't. If I don't have both files open at the same time, they work fine, but as soon as I'm working with both files at the same time, then macros from one file can be used in the other one. Is there a way to avoid that and to limit macros from other files being execute when they share the same Shortcut keys. Here a sample code for the file with Password protection: Sub UnprotectSheets() ' ' UnprotectSheets Macro ' Macro recorded 7/12/2006 ' Keyboard Shortcut: Ctrl+Shift+U ' Dim shtCurrent As Worksheet Dim strP ...Show All

• SQL Server Need to prevent database assembly creation

  On certain servers, I don't want developers to be able to create assemblies. Unfortunately, the command sp_configure 'clr enabled', 0 only prevents the CLR-type from being executed, not its creation . I am unable to rename nor put triggers on sys.assemblies, sys.assembly_modules, sys.assembly_files, and sys.assembly_references . I would prefer the user know the boundaries well before implementation. Has anyone succeeded at this Thanks, that helped quite a bit!

• SQL Server The setup has encountered an unexpected error while Setting reporting service and share point exclusion path.

  I got this error message during install with no error code on Server 2003 SP1. I'm installing on an older development machine and although I do have a very large log file somewhere I wanted to post before I even dug into it. I noticed in IIS under my Webs that the MSSQLExpress webs were there at first but when I clicked on them to get any info or Properties... they dissapeared. So they were almost installed but they no longer exist. Also I do not have a SQL Service Manager icon down near the clock. I almost took a step to fix this. After reading a few posts about similar problems I thought maybe this happened because the Default Web Sites IP # was not set to (All Unassigned). I was going to try a repair install from Add/Remove Progr ...Show All

• Visual Studio Express Editions VB.Net & WMI & BCD

  All, I am trying to use enumerateobjects() in the BCD WMI programming and are having some problems. I have everything working except for this one function. If anyone has any experience with this please help. Here is the MSDN information on it. http://msdn.microsoft.com/library/en-us/BCD/bcd/enumerateobjects_bcdstore.asp My biggest problem is that I am getting a "Type Mismatch" error any time I pass a UInt32 into EnumerateObjects. That is what the value type is suppose to be but for some reason it is not working. I have tried to use Convert.ToUIn32(Cint(1)) and Convert.ToUInt32(CInt("1")) and even just use 1 and many different variations and I always get the same errors. I tried changing the type from UInt32 ...Show All

• Visual Studio 2008 (Pre-release) Creating an instance of class with classname stored in array

  hi all, I have developed an application in which i am storing the interface name and class name in the string array.Depending upon whether it is a class or interface,i want to get the Type so that i could use the class and instantiate it.How could i achieve this.Any help would be appreciated. Regards, spshah This is a bit off topic for the WPF forum, but, you can dynamically load a dll ( Assembly ) using Assembly.Load (...). If the problem is that these assemblies and their references can't be resolved by the runtime, you can hook the AppDomain.CurrentDomain.AssemblyResolve event, manually determine the location of the referenced assembly, then load and return it using something li ...Show All

• Smart Device Development RFID Reader Project

  Hello, I'm currently working on a project which involves a serial port RFID Reader. I have connected the Reader to COM2 of my PC and i'm trying to get the signals from the RFID Tags. I'm using Visual C# and SerialPort class. I'm doing this just to ensure that the code works and when i'm done with this i will modify the code for an iPAQ (the Reader works on COM7 on iPAQ). The problem is that i can't read or write to the port. I even tried to write something to the port using port.Writeline("string") and then read it with Readline() but it seems that nothing is written and nothing can be read. When i set the RtsEnable to TRUE the BytesToRead property changed from 0 to 9 no matter what i did and still i couldn't read ...Show All
