.net - Can A .dll Assembly Be Reflected By C#
Mar 30, 2010I assume because the CLR this wouldn't be an issue?

Reflected Method From A Loaded Assembly Executes Before Calling Method?
Jun 9, 2009When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Executenonquery - Executes Successfully But Changes Not Reflected In The Database?
Aug 9, 2008im using VS2005. and the built-in sql express.when i run my code in debug mode, i can see that the required number of rows are being affected correctly.but when i actually go and see in the table data, the data has not been inserted/updated.i am using sqlcommand. executeNonQuery() to insert/update data.also, i must add that both executeScalar and executeReader are working perfectly.what could be the possible reason for executeNonQuery although showing the number of rows affected but does not actually do it when seen in the table data?int x = cmd.ExecuteScalar(); // X SHOWS 2 OR 3 depending on the number of rows affected.

I just cannot seem to figure out what I need to here:

It is causing errors at the "AddressOf" because Object does not have a method called that. Do I need to do something with an interface?

C# - Loading An Assembly Using Assembly.LoadFrom() As The Assemblies Are Located In A Different Path?
Apr 2, 2012I 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?
"Unable To Emit Assembly: Referenced Assembly?
Jun 1, 2011I'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.

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?

Deployment :: Referencing Assembly From Another COM Enabled Assembly?
Apr 7, 2009I 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.

Use Global Assembly Like A Private Assembly

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?
"System.IO.FileNotFoundException: Could Not Load File Or Assembly" When The Assembly Does In Fact Exist?
Oct 8, 2009One 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've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

Assembly Name And Exe Name?
Jun 12, 2011I have a project, we will call it Asynchronous UPC Scanner (AUS for short). I saved the project with the name of "Asynchronous UPC Scanner" but changed the assembly name and project name to AUS.When I build the exe and run it, the program does nothing but use up 30k memory and they throws an "Failed to initalize..." error. The really weird this is if I change the name of the program to "Asynchronous UPC Scanner" the exe works with no problems....so what is up with that?!
EDIT: OK it seems if I name it anything other that AUS, it works fine...is it possible there is another assembly registered with the same name?
Assembly Cache
Apr 6, 2010I have 2 dll files from a third party, and they have the same name (v7 and v8). My program needs to be able to use both of these dll's (meaning wether the enduser has a lisence for v7 or v8 of the thirdparty dll, they can still use the program). But I am stopped from referencing both of them as they have the same name. How do I resolve this? Searched the web and found info about sn.exe and strong names, but can't find a good explanation of how this works. Anyone?

View 17 RepliesHow To Use A Signed Assembly
Mar 20, 2011I'm learning about GAC and signing assembly! And I have some problems...1. I make a DLL having some basic functions in ONE SOLUTION (Signed and Compile)2. Then, I make a FormApp, add a reference to this DLL and using its function to do somethings in OTHER SOLUTION. No error appears!3. I run this project, so I get an error:A call to PInvoke function 'MyDLL.LunarDate:: ' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
I tried 4 possible abilities that I can image:
1. I unsign DLL and re-add it to FormApp : It's OK
2. I sign FormApp with same pnk : The same error
