Dynamic Exclusive Library Runtime Linking?
Aug 4, 2010
I have a .NET library which I know can be fairly easily linked from VS project to reference it from code. However for security reasons I want to place the DLL file in another location on the disk and reference it from code including executing methods and passing method parameters.

I am presently working on a bluetooth appliance project using Rabbit's embedded blue RCM3100 microprocessor. The microprocessor is programmed using Rabbit's software dynamic C (Combines C and assembly language). The problem is, I would like to create a GUI (graphical user interface) using VB.net to communicate wirelessly via bluetooth with the microprocessor. How do I link VB code with dynamic C?[size=7]

I am unsure why all of the sudden i am getting this error every time i compile and run my VB.net program running Oracle 10g. It ran fine many times but all of the sudden keeps saying this now.
[URL]
It happens on this line:
myConnection = New OleDbConnection("Provider=OraOLEDB.Oracle;Data Source=(DESCRIPTION=(ADDRESS_LIST=" & _
"(ADDRESS=(PROTOCOL=TCP)(HOST=" & dbHost & ")(PORT=" & dbPort & ")))" & _
"(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=" & dbServiceName & ")));" & _
[Code].....
Once it gets to the myConnection.Open() is when it displays that error box. Like i said, i used to work just fine.

I am looking for sample linq code snippet which uses System.Linq.Dynamic against a datatable.
Dim entities = (From ent In dt.AsEnumerable().Where(String.Format("IsUSFederal == {0}", "true")) _
Select Description = ent("Description"), Acronym = ent("Acronym")).ToList
I am getting an error "there is no accessible Where can be called with these arguments". I have included the DynamicLinq.vb file and the application compiles fine (aside from this error). I have included Imports System.Linq.Dynamic but it doesn't appear to be working.

I'm creating a project with an Add-on system, and I'm releasing an API so people can develop for my application (its called Levanta, its a basic Sub-OS, and i want people to be able to develop for it). I try to call a sample DLL i made to test out the system i created. Well, i CANT, because its not finding the functions entry point of the said function (its named initialize)...?

My program used to run on my system just fine until I removed some other applications. Then the proggy was giving me a runtime error. The funny thing is that once I installed visual basic 6 and added a reference to dao360.dll, or the Microsoft DAO 3.6 that the program then worked without error.
VB6 was never installed on this system before. The program worked just fine until applications were uninstalled from the system. What happened that caused the reference to stop working? Why did the program stop finding dao360.dll even though the program itself wasn't modified since vb6 wasn't installed?

GetProcAddress Function Retrieves the address of an exported function or variable from the specified dynamic-link library (DLL).Lets say I have something like this:
Dim moduleHandle As Integer = LoadLibrary("C:myDLL.dll")
Dim methodName As String = ""
GetProcAddress(moduleHandle, methodName)
DLL should be win32 standard dll or .net dll.
How can I run the exported function if I have the address of it through GetProcAddress().If someone could supply some code it would be great.

i added the COM reference to:Crystal Reports 9 ActiveX Designer Run Time Library 9.0 i have some code that prints a crystal report:
'print report
Dim Appl As New CRAXDRT.Application
Dim CrystalReport As New CRAXDRT.Report
[code]....
Code works fine on my Windows 7 64 bit computer because I have Crystal Reports 9 installed on that computer but i want this to work on other computers that don't have Crystal installed.I have published my app and installed it on another Windows 7 64 bit computer and it doesn't work.I think i need to have the craxdrt.dll install and register on the users computer.
how can i include this in my setup? I already include the Interop.CRAXDRT.dll when i publish (publish status: INCLUDE/Download Group: Required/Hash: Include) but it doesn't make a difference.i am using vb.net 2010 express?

I am trying to create a number of objects depending on the width of a row of an array, is there a way I can change the name of the variable being Dim 'd as I don't know how wide the array will be.
I have been trying something along the lines of:
pseudocode
For x as integer = 0 to UBound(MyArray,2)
Dim Object & CStr(x) As Object Type

You can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings
Public WriteOnly Property RunTimeConnectionString()
Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
My.Settings.RunTimeConnectionString = My.Settings.ProductionConnectionString
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?

I use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).

I am working with a simple game idea. I wanted to have two players running around shooting each other (very low graphics, like circles and squares). I've got this far; I have the ability to move around both characters, and change directions etc. ive also been able to set up my shooting. Only problem I run into is getting the bullet to move! I cant use a preset timer, because if I used that, I could only shoot one bullet at a time, so I would need to create new ones dynamically.
So my question is; how does one add dynamic timers to a form on runtime, and alter the tick sub so that it moves the picturebox (bullet) and once it can be moved, (I was thinking about using player locations in relation to the bullet, and if they were equal than the health would go down or whatever, but unfortunately, this means it would have to be directly in the middle of the player, which would be odd..

I have a nested content page within a master page, upon load the the page retrieves from a SQL a list of controls to create (Field Type, FieldName) i.e. String, Username.The function loops around the list creating the controls on the webform in a Placeholder, this part works perfectly. The problem that I am experiencing is the request to obtain the value entered by the user in the dynamically created control, I need to perform this call following postback/callback.
If I take the Content page and make it a standard aspx page with no master page the application works fine. Unfortunatley taking the page out of the master page is not an option (unfortunatley a restriction by my client)

I'm developing an application to allow engineers to conduct simple single table/view queries against our databases by selecting Database, Table, Fields.
I get how to use the Dynamic LINQ Library Sample to provide for dynamically selecting the Select, Where and Order by Clauses at runtime but I'm at an impass on how to allot for table choice.
Is there a way to provide for dynamically selecting the "from" table at run time
EDIT
So Both of the answers seem to be saying the same general Idea. I'm going to try to convert the C# into VB and get it to work.
The first answer converts to
NotInheritable Class DataContextExtensions
Private Sub New()
End Sub

I am new in programming. And I am coding with VB.Net (VB2008). On my form I have 9 checkboxes. And each of this checkbox when checked is meant to submit a value to a dynamic array. Initially the array was a constant that was declared like these:
Dim Notes() AS integer = {1, 2, 5, 10, 20, 50, 100, 200, 500, 1000}
But I want the array to be dynamic. That is the user of the program is to enter the element of the array. So I decided to use checkboxes. So that if the user of the program checks any of the checkboxes, a particular value or element should be submitted into the array. And the user should be able to check as many checkboxes and have values representing those checkboxes submitted in to the array.
For example: if the user check checkbox1, checkbox2 and checkbox50.
The array should look like these. { 1, 2, 50 }
or if the user check checkbox1000, checkbox200, checkbox10 and checkbox500
Then the array should hold or contain the following integers in this order; {20, 200, 500, 1000}.
That is the array is dynamic and the content/elements of the array and the bound of the array should depend on the checkboxes that is checked. What other means can I used to enter values/elements into a dynamic array during run time.

In an application I build a list of CheckedListBox and display it to the user. I want to make the selection exclusive to only one. I noticed that you can check more that one item in the CheckedListBox. How can I stop that and as the user check the second box I uncheck his/her first selection.
SForm.ChkBoxPts.Items.Add("Paarsa")
SForm.ChkBoxPts.Items.Add("Jeff")
I.e. If I display the above two items or may be even more, I would like to force the user only select one and only one.

I'd like to open a text file and not allow any other processes to write to it. I understand I can do this with the following FileStream:Dim fs As New FileStream(_FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read)
Once I have access like this I need to read all of the lines (I will use a StreamReader(fs)) and then I will need to write to the file (I will use a StreamWriter(fs)).
The problem here is that the StreamWriter won't allow me to set the append mode to false (so I can overwrite all text in the file) when I use the filestream as a parameter instead of the file path. So all text written with the StreamWriter is appended onto the text which I don't want. If I use a StreamWriter with the file path (which will let me set append to false) as the parameter instead of the filestream it will be locked out because of the FileStream FileShare. How can I still have exclusive access to read and write to the file but still be able to overwrite the existing text (append mode false)?

I have a solution in VS 2008 that creates a DLL. I then use that DLL in another application. If I go in to the DLL projects property pages and change the following configuration for a DEBUG build then the built dll no long provides the desired functionality. If I change it back and rebuild the DLL, then the DLL does provide the correct functionality:
