• .NET Development Object Already Exists error when trying to sign an assembly using a pfx file

  Hi, I'm trying to sign my assemblies using a pfx file. This was working fine, until I changed the file I used to sign it (I used to sign it using xxxx.pfx, and now I'm signing it using another xxxx.pfx, so the name is the same but the file itself is different). When I point to the new file on the signing tab and build my solution, I am prompted for the pfx password. When I type in the pwd and confirm, I get the error message "Error Importing Key" "Object already exists". For me, it is not clear what is going on. Could someone clarify what I should do to avoid this problem. I already tried to apply the workaround suggested here http://www.pcreview.co.uk/forums/thread-1325523.php , but to no avail. ...Show All

• .NET Development Webservice: "The ASP.NET process identity does not have read permissions to the global assembly cache."

  I'm uncertain what the best forum is for this - I also posted this in the ASP forum.

• Visual Studio Team System Difference between stakeholders and constituents?

  Stakeholders and constituents sound like the same group of people. What's the difference between them Are they interchangeable For example, an end user is a stakeholder to a project, can I say he is also a constituent for that project Thanks in advance. Hmmm... it is a tricky thing to define a constituent that way because a constituent is a noun, concept or cause being advocated by member(s) on the project team. In other words, it can be a nameless user or a collection of users. In such cases, things like user profile(s) are used to represent them, their interests, their needs, their wants, etc. It is rare that a project team meets all of its constituents. Conversely, stakeholders are named and r ...Show All

• .NET Development which assembly will be called?

  Hi, I am studying .net and run it this question: Assembly A calls a private assembly B to do some function. B is located in the bin directory of A. Later you You assign B a strong name, set its version to 1.0.0.0, and install it in the global assembly cache. In this case, which B the assembly A will call is it still the B in bin or it is from global assembly cache Many Thanks Jerry Hi Suresh, The assembly in bin is not recompiled, so still the private assembly. Only the one in GAC is recompiled. So it should be bin first, isn't it Thanks ...Show All

• Visual Basic Setting MessageBox returnValue to Yes

  I have created a dedicated WebBrowser application that is only used for viewing a program containing dynamic web pages that runs on my computer. Some of the web pages in the program utilize activeX controls so when I open up a page containing activeX controls in my dedicated WebBrowser application I get the following warning message box. An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction I click the “Yes” button and all is well. It is just that the repetition is annoying. If I set the “ScriptErrorsSuppressed” property of WebBrowser control to True, I don’t get the warning message boxes, but the activeX controls don’t work either. Is ...Show All

  Got an odd problem. 9 months ago I wrote a windows service that displayed a message to staff. The service was set to interact with desktop so that the window would display when required. The Topmost property is set to true Now, with no change to the code and after many months of this working perfectly the window now does not display on top af all other windows on ALL work PC's. But on my development PC which is not part of the work network it still works perfectly. I use VB.net 2005. Hi Martyn775, I found this thread looking for a solution to the same problem - only my application resides in the system tray. I did confirm that it works fine under IE6, but not IE7, by testing in VirtualPC. I ...Show All

• .NET Development generics and static methods question

  I'm learning generics and c#. Is there a way to call static methods in the T class so I can streamline this I have two static methods in T named GetItem and SaveItem that I would like to invoke by something like T.GetItem(astring) and T.SaveItem(t). Reading some of the other posts seems to indicate that a static method can not be used. Thanks for any recommendations. public class FrmUpdateManager <T> : Form { T t; // etc // would like to do something like T.GetItem(tb.Text) to eliminate the if clause // for each type I implement i f ( typeof (T) == typeof ( InsuranceCompany )) { object obj; obj = ( InsuranceCompany .GetItem(tb.Text)); t = (T)obj; displa ...Show All
