How would I change this code to make the factory dynamic. I believe I was close with remoting. I don't want any hardcoding of the factory, nor do I want to have to recompile. The database drives it.
Dim genericRule As Rule
Dim factoryObject As String
factoryObject = _dal.GetFactoryObject(ruleId)

View 2 RepliesMy environment is VB6 (NOT .Net), and I have three function-similiar com+ DLLS with different GUID. For example, DLL A, DLL B and DLL C have the same function Beep(). I have a VB application, if I want to use DLL A Beep(), I should import the DLL A reference, and rebuild my application. If I want to switch to DLL B Beep(), I have to change the DLL reference and then rebuild my applicaton.. The same to do if I do with DLL C.

View 2 RepliesI have an MS access database with some .dbf files linked to it. One of the dbf file is a sales file. I am trying to generate a report for each of the month's sales. For that the sales dbf file will be different for each of the month. I want to give an option to the user to specify the file name from which he wants to use to generate the report. After accepting the input from the user, i need to link to that table in MSACCESS. Is there a way to achieve this from vb.net

I am working on a little project and am having some issues with a checkbox. I am adding a number of checkboxes to an ASP table via code by adding rows and columns dynamically. This all works fine except for when I go to check them based on loading a preexisting record. For some reason some of the checkboxes are getting set to TRUE when the new row is added to the table.

i'm building a basic server program that I want to recieve commands and execute them sent from a client program and I'm using my home network to test it out. I've got no problem with the communication between the client and server programs and have used a simple Send Text function to communicate to the server program which simply brings up whatever text was sent in a message box.
I've decided that constantly updating the program and transferring the new EXE file just doesnt work as I have to keep starting and stopping the server program to do that just to update the list of commands it recieves. So say for example I've got a button on my client program that tells the server to open the cd-rom draw on that computer, it sends this in the form of simple text openCDdraw" and when the server recieves this, it pops open the cd draw and so on and so on... but I thought a better way of doing this may be to say have the commands listed in a SQL database and when the server recieves a message it searches through the database to find the correct command and executes the code associated with the command.
Now I can retrieve the information fine in to a string variable ("Dim a as string, a = dr.getvalue(3)") but where do I go for there? This is the problem see. My apologies if I've gone a bit long winded on this one but thought it necessary to explain what I'm doing. I've heard of dynamic code execution but when I tried a project I found on the internet it had been coded in C# and I don't know any C nor do I want to as I'm a VB veteran and have updated myself with the way of .NET now so am not going to start all over again with learning C. Does anyone know of an easier way of doing this? Static code is so easy to do because it is typed straight into the coding sections and I had already thought about creating loads of subs/functions to execute each command but again that involves updating the EXE file every time so there must be a better and easier way of doing it.
Can I also just point out that this little project i'm working on is not for a TROJAN or whatever that old NETBUS program used to be called, it is simply so I know how to do it and can use it for other things that I'm working on and through. Also I'd just like to know how to retrieve and execute code from a database or text file.
I am using some interesting code to perform dynamic unmanaged dll calling:[code]I want to be able to change the parameter signature and type of the delegate to void or to a function returning integer, string, or boolean.Basically, I want my program (interpreter) to be able to call upon any method in any unmanaged dll that the programmer has access to since I cannot predict what method the programmer will want to have access to - I'd like to enable them to have access to any useful method.[code]This raises a complaint on the line with 'Dim theResult = ' on it. The error is "Object of type 'System.Int32' cannot be converted to type 'System.Object[]'."
View 1 RepliesI've a DLL assembly reading a variable, "GalleryID", from an XML file. I can't modify the assembly, so I am wondering if I can make the XML element value dynamic? For example, to get this value from a querystring or any other scenario without changing the assembly.[code]This is an ASP.NET website that has multiple users. When a user logs in and open the gallery.aspx page it will show the user's own gallery. This scenario is not working now since the gallery module shows one gallery (Galleryid=2) to all users according to its setting in Settings.xml file. How can I pass galleryid in querystring -- gallery.aspx?galleryid=5 and inject it to Settings.xml file?

I have never dealt with dynamic control events before. I have a variable number of a controls each created at runtime. However I don't know how to code events for each control as they should do different things. I've looked at WithEvents and AddHandler and know I have to use Sender however not sure how to use /where to put eg. MouseEnter 1 panel when there's several.
View 5 RepliesI use the following code to fill the Table1 dictionary with the information found within the LINQ query.[code]....
View 2 RepliesI'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?
I have the following linq query:
Dim q = From definition In definitionList _
Where definition.ValueDefName.Contains(criteria)[code]....
I have already looked into this answer: LINQ - dynamic WHERE clause?Unfortunately, it doesn't work for me using .net 4.0. When I attempt to pass the criteria string in it ask for a predicate. The end goal is to add any of these:
definition.ValueDefname.Contains(criteria)
definition.ValueDefDesc.Contains(criteria)
definition.Aliaslist.Contains(Criteria)
definition.StrategicInitiative.Contains(Criteria)
to be passed into the query depending on what checkboxes the user has selected. How can I create a dynamic where clause in linq to sql? Is there new syntax for passing in a where clause as a string?

Ho can you make a dynamic label stay right justified, so that when the label.text is filled the text starts at the right edge of the label and fills to the left? Currently the text fills to the right from the left edge of the labels location and tends to run off the form.
