C# Version Of CTypeDynamic ?
Jul 12, 2010
From the documentation:
The CTypeDynamic method applies dynamic conversions in accordance with the conversion semantics defined by the object itself. If a dynamic object inherits from DynamicObject, the CTypeDynamic method first attempts to perform the conversion by using a user-defined, static conversion. If the user-defined, static conversion fails, the CTypeDynamic method attempts to perform the conversion by using dynamic conversions. If a dynamic object implements IDynamicMetaObjectProvider, the CTypeDynamic method gives precedence to dynamic conversions over user-defined, static conversions.
Is there something in C# that does this? Or do I just have to import the VB library that has it.

How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?
And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?
BTW I am using VB if that makes any difference.

Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.

I'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:
'OS Check
Dim osValue As Object
osValue =
My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrent Version", "CurrentVersion", "5.2")
[Code]...
*Note - 5.2 is Windows 2003, 6.0 is Vista, 5.1 is Windows XP

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

A few years ago I started development of an application using VB6.0. We shelved the project but are now looking at reviving it. In addition, we are looking at developing another application that we probably could design using use VB. Our OS: PC, XP SP3; Server, Windows Server 2000.
We plan to use both applications in our business; however, we believe there may be opportunities to develop and market both.What versions of VB are available? Is Visual Studio VB? [Please excuse my ignorance... I did not stay at a Holiday Inn Express last night. :)]
What version of VB would be best for us to use?

I am a heavy user of Telerik's library of controls, specifically for ASP.NET. However, there is a small bit of functionality which I wanted to add to some of the controls. Nowadays I can do this easy enough using Extension methods. So I wrote a small library which does exactly that. Obviously, this library needs to reference their DLL (Telerik.Web.UI.dll).In the My Project > References page of my DLL project, I have a reference to Telerik.Web.UI.dll. For this reference, I have the Specific Version property set to False, because I don't want my library to care about what version of the Telerik DLL is being used. THIS is my problem though... the .NET compiler doesn't seem to honor this setting.
Case in point, I have a website which references both the Telerik DLL and mine. I updated the Telerik library to the latest version. Now when I try to run my website, I get: Could not load file or assembly 'Telerik.Web.UI, Version=2012.1.215.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)I fix this by going to my DLL project, recompiling it against the latest Telerik DLL, and then updating my DLL in the website. This is precisely what i didn't want to have to do every time I update Telerik's library. I thought that setting Specific Version to false would mean it would work with any version. No?

I just ran into a problem that I did not really give too much thought to when I started building my app .I'm releasing the first version of a fairly sizable application to my users. There are going to be two types of changes: Corrections and Enhancements. If a correction is required (ie, user finds an error in the app and I need to fix it right away) I will make the change in the code, and republish the app for the users to dwnload.My problem is that I have to start working on the second release objectives, and that requires changing some of the underlying structure of the app... that being the case, I cannot accomplish this in the production version of the app and thereby need to create a test version to parallel the production version.
If I do this, how do I merge the two applications later? If this was two excel files, I would just save the newest one to override the old one (when ready for release2), but there is no "save project as" in vs.net (2008).

"Error # 5 was generated by Microsoft JET Database Engine" regarding databases created with earlier versions of Microsoft Jet. This is nice and true, for instance the function using GetOleDbSchemaTable creates the error.(schemaTable = cn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns, New Object() {Nothing, Nothing, tblname, Nothing}) )
But how can we find out which version was used? In VB 6 we could get the database version using Set db = OpenDbRead(Dbase)Version = db.Version db.Close And we could get the Engine version through: DBEngine.Version But in VB.Net, can that be done? How?And then hopefully the problem can be solved via the .CompactDatabase function.

I'm working on a VB.Net Project and someone suggested me to use the VB2008 IF(a,b,c) operator. I think I am using VB2005, but I can't find where to confirm that information.
Also, is the server's IIS version important for the VB version used? (I think so, but I'd like confirmation... And a way to know what IIS version match what VB version).

i have a strange problem with a VB.Net Windows Application. On my computer(the development PC) it executes the newest version of the exe and dll's but on the computer of my fellow(he is not a developer and cant debug it) an older version is executed. He has overwritten all files with the new version:
I dont know where to start looking for the reason.
EDIT: the first thing i've done was to restart the pc of my fellow but that was of no use.
When is a dll installed in the global assembly cache? Because i've searched for it in the gac with gacutil.exe but not found:
C:>C:WINDOWSMicrosoft.NETFrameworkv1.1.4322gacutil.exe /l Rule.dll
Microsoft (R) .NET Global Assembly Cache Utility. Version 1.1.4318.0
Copyright (C) Microsoft Corporation 1998-2002. All rights reserved.
The Global Assembly Cache contains the following assemblies:
The cache of ngen files contains the following entries:
Number of items = 0
I've also looked into the assembly folder but not found any of these dll's there.
Additional info: one of the dll's is loaded dynamically in the codebehind:
System.Reflection.Assembly.LoadFrom("Rule.dll")
The others are referenced in the particular project.

I have recently been trying to use the extension functions of the generic collections in VB.NET. I have .NET 3.5 installed, however it appears that my project only uses libraries of version 2.0. How can I force VS2005 to use the 3.5 versions so that I can access the extension functions? A C# developer in our office could not find the comparable setting in the VB Project Properties dialog for setting the compiler to use 3.5.

My VB.NET 2010 app currently targets .NET 3. I have to update it to target .NET 4 to get around some Locale / CultureInfo issues. What's the difference between .NET 4 Client Profile and the other .NET 4s I have on my machine: Extended and Multi-Targeting Pack? Which flavour of .NET 4 should I target? I want to target the flavour that the average user running Microsoft Office (Excel/Word/Outlook) out in the wild is most likely to already have. Why (on my machine) is there only a regasm.exe for v2.0.50727 and v4.0.30319? Why not a separate version for the other versions installed on my machine? (3, 3.5)
