.net 3.5 - Change API Reference At Runtime?
Feb 15, 2010I'm writing an application for a device running Windows XP. There are 2 versions of the device and each version has its own API to communicate with the device's software. The application I'm writing needs to pull the same data from the API. My question is how to write a application that will detect at runtime which version of the device it is on and use the appropriate API.
I've created an interface containing all of the common methods and also classes for each device that implement the interface. Now I need to know how to activate the correct one at runtime.
Public Interface IAPI
Sub InitializeMachine()
Function GetActiveProgram() As String

Reference Objects (from NET Assemblies) At Runtime?
Jan 8, 2010I created a .net assembly, which works perfectly if I create before runtime. But i'd like to know if it's possible to reference at runtime. The reason is because i'm creating an application which will be used in several servers, and it will be reference that same .net assembly, but the .dll file will be in different location per server. I know that when I reference before runtime, the .net assembly it will be pointing to is from the original (or at least that's what I think).
View 2 RepliesReference TabPage Created At RunTime
Jan 16, 2012Been searching a trying examples for a couple of days and always fall back to the "null reference" error on this one. I have a set of instructions coming from a SQL database and the number of instructions is a variable. Therefore, I have a TabControl which I add TabPages to at RunTime depending on the number of instructions there are. The TabPages are then created with the names; Step1, Step2, Step3, etc.Each TabPage is made with the same controls and all of the controls are named the same from page to page (e.g. "instr" is the name of a TextBox control that exists on every TabPage).I can successfully create a GetControl method that will return the correct TabPage, but I cannot reference any controls on that TabPage.I can only change properties of the TabPage.If I try to reference a specific control on that TabPage, like the "instr" TextBox control, I get the null reference error.[code]

Nov 26, 2011Is there a way to change reference at runtime ? I am automating Word from VB.Net. I think what I have coded will be same for both Word2003 and Word2007. I used Word 12 Object Library reference(which is of Word2007). So, I want to know how to make it compatible with a machine installed with Office2003. That is, it will check the whether the machine has 2003 installed. If so, use that reference. Otherwise use 2007.

Include Reference Dll When Compiling Program?
Sep 14, 2008I've made a program using Visual Basic Express Edition which references MySql.Data.dll (located at C:Program FilesMySQLMySQL Connector Net 5.2.3Binaries.NET 2.0MySql.Data.dll) which has been installed on my computer. But when I run my compiled program on a different computer (without MySQL Connector/.NET installed) I am unable to start the program as it gives me an error.
I'm wondering if there is a way to compile the dll with my program so that I wouldn't have to install MySQL Connector on the only computer it'll be executed on (I'm not sure if I have the privilege to install programs on it yet).Or is there a way I could import the dll at runtime which is located in the same directory as my .exe?

View 2 RepliesAdd A Reference So That Oracle Database Can Connect To Program
Apr 25, 2011Well for some reason when i try to add a reference so that the oracle database can connect to the VB.NET 2010 program.In other words it shouldn't highlight certain code as if the database is not connected.Here is a clear summery as best as i can say what the problem is.
1. Connection from Visual Studio 2010 to Oracle plus server
2. Adding References will not be allowed for some reason.
3. The code (See example below on what it might be) is still highlighted even when i added the references several times.
I'll show just a small snip of the code coz it's more or less the same on most of the forms if i want to either update, delete, add or amend to the database. I'll show a few screenshots so to be clearer.I've tried by even looking over the notes and followed step by step and nothing works.Since i am not registered in this module this time i can't seek help of the lecturer so don't bother telling me to go and ask my teacher I've pestered the supervisor that i'd have to present this project to and she hasn't replied to my email at all so i have no clue what else to do in the matter.
