VS 2008 Ngen Fails With Any Assembly
Jul 2, 2010
I am a software developer. I work with Visual Studio 2008, Visual Basic, Windows Seven. My program is developped with framework 2.
Everything was going fine until two days ago when the ngen utility has stopped working.
I use ngen utility on post-build event for some assembly.
I try to use ngen on command prompt the result is this:
C:Userslucam>C:WindowsMicrosoft.NETFrameworkv2.0.50727
gen.exe install c:
NUOVAMACUTSourcesNMLibinNMClassCreator.dll

I have recently upgraded an VB6 project to vs2008. I was almost finished when the following error occured. Unable to emit assembly: Referenced assembly AxInterop.MSFlexGridLib does not have a strong name Prior to this error appering, I tested my app several times and it was fine. Only after publishing it did the error appear. I have tried all solutions I could find, but nothing helps. I have read [URL]

If Ngen doesn't protect my application, when would I reasonably expect to use this application in my career?

Does anyone use NGen to generate native images of their assemblies? I have always been quite puzzled by NGen because all MS articles that describe it basically make it sound like it has quite a few advantages compared to the disadvantages. Basically it looks like it will improve the speed of your application in most cases but if that is the case then why doesnt everyone use it all the time?or maybe they do and its just me that has not really used it much.The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local computer. The runtime can use native images from the cache instead using the just-in-time (JIT) compiler to compile the original assembly.

When running setup to install published program, the following message occurs: System Update Required: Unable to install or run the applicaiton. The application requires that asssembly CrystalDecisions.CrystalReports.Engine Version 10.2.3600.0 be install in the Global Assembly Cache (GAC) first. This version is listed in the references of the program and in my mind, be included in build. How do I get by this error?

I receive this error as "Assembly Load Error" whenever adding a form or other object that has to be inherited.
"Unable to load assembly. Ensure that the file is a valid .net Framwork assembly"

I am loading an Assembly using Assembly.LoadFrom() as the assemblies are located in a different path from Application Base directory.
Dim oAssembly As Assembly = _
Assembly.LoadFrom("C:\MyFolder\" + ddlXlate.SelectedItem.ToString() + ".dll")
And I consume a Type from that assembly without any problem:
oXML = CType(oAssembly.CreateInstance(sBaseType + ".XlateContainer"), _
XlateBase.XlateContainer)
However, the problem occurs when I try to use a Type from this assembly from within another method like the one below:
oComboBox.DataSource = _
[Enum].GetValues(Type.GetType(sType + "+ItemEnum," + sAssemblyName))
sAssemblyName is the one I loaded using LoadFrom() actually. After it said it cannot find the assembly, I used AssemblyResolve event which solved my problem :Subscribing AssemblyResolve event :
AddHandler AppDomain.CurrentDomain.AssemblyResolve, _
AddressOf MyResolveEventHandler
Event Handler Method:
Private Shared Function MyResolveEventHandler(ByVal sender As Object, _
ByVal args As ResolveEventArgs) As Assembly
Return Assembly.LoadFrom("C:\PSIOBJ\" + args.Name + ".dll")
End Function
And I thought maybe the error occurs because it cannot find a dependent assembly defined in assembly manifest file I loaded using LoadFrom() already but when I checked the args.Name, I saw it was trying to load same assembly and after that it worked without any problem. So basically a type in the loaded assembly cannot be found before the event adding change.
My old code was using AppDomain.CurrentDomain.Load() and Assembly.Load() methods and they were working fine without the AssemblyResolve event. I was able to reach types in dynamically loaded Assembly from every where within the same AppDomain.
LoadFrom() can find dependencies automatically within the same requested assembly path and that couldn't be problem as everything this dll needs was there. So at first it looked like a AppDomain problem to me as it looks like it seems it can reach assemblies from Load context instead of LoadFrom context and I am now using LoadFrom context.But now it seems I should pass oAssembly instance evertwhere to use any type from the loaded assembly?Doesn't it load the assembly where I can reach it everywhere (same AppDomain) using simple Type.GetType(...) method?

I have an app developed in VB that works fine on Vista machines but fails on Win7. The offending line of code merely references a variable stored in a module. Evidentally, something is quite different on Win7. How to I find and fix this behavior?
The code is very straightforward. The error occurs in the Application Startup event.
Public Sub MyApplication_Startup(ByVal sender As Object,
ByVal e As ApplicationServices.StartupEventArgs) _
Handles Me.Startup

I'm wanting to include a system tray icon in my WPF project, and found this resource:[URL]..which looks like it will work beautifully, but it's written for C# and I'm using VB.net for this project. I downloaded his project and built the notifyicon as a DLL, then added as a reference to my project.
It throws up an error: Unable to emit assembly: Referenced assembly 'Hardcodet.Wpf.TaskbarNotification' does not have a strong name So I'm trying to figure out the best way to proceed. Do I need to strong name it, or is there a better way to do this?

I've got an exception when I deployed my application: "the located assembly's manifest does not match the assembly reference" What I remember is changing the project name from the previous source code, does it affect that much?

I have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.
I have been using visual studio 2008 and sql server.Code I have been using for ::
'Update the Records Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click

For some reason i can't select text with the mouse in my application.Also my clients experience the same behaviour.I know it was possible to select a part of the textbox and it stayd selected. Now the selection dissappears and the cursor moves to the front.Only a doubleclick functions properly but selects a single word only.

I have a class that inherits from control with some custom properties added, and I am using a propertygrid to change the properties at run time. I don't want any of the inherited properties of the control available in the PG so to each of my class properties I amassigning a CategoryAttribute and I am adding the same categories to the PG.BrowsableAttributes collection. When I add a single category to the BrowsableAttributes collection it works fine, but when I add more than one, none of the categories show up in the PG. I am wonding if there is a simple setting in the PG, or if I have missed something setting it all up.

I have created several DLL (.NET) libraries that are used in several projects. In these DLL libraries I want to know/retrieve which assembly (EXE) calls/uses the library, so if possible I want to know info like assembly name (EXE), strong name, version number, etc.
NB: Examples may be in C# or VB. I use both languages.

I have written a .net assembly which plugs into to a third party COM application. The .net assembly is COM visible to the third party application. However this .net assembly references other regular assemblies. If I put these assemblies in the GAC the COM visibile assembly sees them without a problem. However for various reasons I do not want to put them into the GAC but I cannot get my COM visible assembly to see the other assemblies when they are in other locations. I have tried putting them in the same directory as the COM visible assembly. I have tried putting them in the same directory as the third party app's exe but neither of these work.

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.
Alternatively, if that's not possible, how about checking the modules in an assembly?

I am building a dll-Assemby A which references another Assembly B. Assembly B is strongly named and installed in the GAC of my development computer. An other computer will not have assembly B installed in the GAC.
Question: If i handle strongly named assembly B like a private assembly and copying it into the bin-directory by specifying local copy = true in the properties-window, will the programm run on the other computer?

One of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.

I have created a .NET assembly, clicked 'Register for COM Interop' on the properties page, strongly named it and compiled it. Then I GAC'd the .NET DLL manually. Calling the .NET assembly from my VB6 code with 'CreateObject("MyNETProject.class1")' gives me an automation error. I've gone through about 3 iterations of this for most of the day and cannot sort out what I'm doing wrong. I have a feeling it's got to do with my .NET assembly settings and GACing but it all seems right.

When I go to my project properties I can see the Assembly Name under the Application tab. Now if I click the Assembly Information button I see some other settings such as title, description, company, etc. I can get the name by doing: Assembly.LoadFile("c:\filepath").GetName().Name.ToString()My question is how can I get the title, description, company, etc. I have tried a few things but nothing seems to work. Also I was told that you can create custom settings. How would you do this and how would you access them?

Basically, where in the solution do you put:
