Calling A Function That's In A Module In External Application
May 25, 2012
I have an application (app.exe) that has a VB Module in its source code (Module1). The module has a function called Function1. I need to call this function from another application. The module is not marked as public, so adding a reference to app.exe won't work. I'm trying to use reflection (Assembly.LoadFrom()) but unless I'm way off base, the module would have to be a class in order for me to get an instance of it.
Please nobody ask me "what have you tried?" I tried a million different things and let's just say "none of them work." So I'm looking for someone that has specific experience with doing exactly what I'm trying to do. If you don't have that experience, please move on to the next question and ignore mine.

I have an 100 aspx files with one module file for code. All these aspx files have the same backend function, so i created on public module for all these files to access. These files are in the same folder. But for some reason the aspx files cannot access the function from that module.
mod1.vb Code (.vb file)
Public Module Allinone
Sub Allinone_Load(ByRef Page As Web.UI.Page)
[Code]....
I am at a roadblock of why the aspx files wont read this module? Also all these files are in the same directory

I have a console application consisting of two modules. One module named "quote" is the main module for the application. Another module named "common" contains commonly used functions and subroutines that are shared between multiple applications.
In the "common" module is a function named "quote". If I attempt to call the "quote" function from the module named "quote", then I get the following error: Error 1 'quote' is a type and cannot be used as an expression. However, if I copy the quote function from the "common" module to the "quote" module, then I no longer receive this error.
There shouldn't be an issue with calling a function that happens to have the same name as a module, but only when that function is located in a different module.

I'm using a 3rd party DLL to access a proprietary Database. It's designed to invoke a function called "CALL_ME_FUNCTION" to make the datarows available to my program. What makes it difficult is the CALL_ME_FUNCTION is in the VB program and therefor, external to the DLL iteself. I've got the CALL_ME_FUNCTION written in my program, but how do you give access of it to the DLL? I've written lots of code that invokes functions inside a external DLL, but this is the first time I've encountered a DLL that needs to run a VB function.

I am wondering if it is possible to call an application, say "notepad.exe" (among other application's that are already open) and setting focus on the same, so the user can readily start working on it.

Is it possible to call a function within an asp.net web application from outside that application e.g. with VB.net? If so it would be great to see a hello world type example.
For arguments sake lets say I have my function "helloworld" in a class file within web application: [URL]
My ultimate goal is to enable some reliable / robust scheduling of functions within asp.net. I have read multiple examples about using web services / custom services running on the server etc but I don't really get the implementation.

I'm trying to do something which i am not sure is possible, im hoping someone will be able to prove me wrong.I have a desktop application written in VB .net which needs to post to google analytics, the interface they provide is javascript based. At the moment my application opens an internet browser, goes to a specified URL which in turn executes the javascript contained within, this is cludgey and memory gobling!
Is there any way of importing a javascript file and calling a javascript function without opening a third party browser? would preferably not want to use the browser control either.Is there a way of instantiating for instance a javascript engine and passing it the commands?

Normally, when you create a HTTP module, you create it as separate dll project and register that dll in the web.config.Now, is it possible to write a HTTP module directly in an ASP.NET project, so I don't have to create a separate dll project?Note: Don't say as an added project in the same solution, I mean in the same project.Or would just adding a reference to this dll suffice ?

I would love to use the following procedure to set the Title, keywords etc. of my pages, in a module.
Public Shared Sub SetTitle(ByVal Heading As String, ByVal Keywords As String())
Dim myMaster As Masterpage = DirectCast(Me.Master, Masterpage)
If Request.QueryString("lng") = "es" Then
[Code]....
The problem is that i get two errors.
At Me.Master i get the 'Me' is valid only within an instance method. error and at
If Request... i get the error
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
So how do i fix these? I would like to have that procedure in a common place and not in every page.

I have been given an ASP.Net assignment at work because I had taken a few courses a couple of years ago. Currently, there are no ASP.Net programmers for me to ask here and I have searched several places (including Pro ASP Net book) to find a solution but have come up empty handed.
I have a class named spErrors which takes the values passed to it. Values passed include the offending page,function/sub, and other values and stores them in property values, then calls Response.Redirect("Errors.aspx") from the page's code behind page. In Errors.aspx, the values of the error/exception trapped in the Catch statement are displayed. This works fine from a web form. My question is, how do I call a web page from a class module?
Each class module has the ErrorHandler() procedure that passes these values to the class object. In the class, there is a Write Only property named Redirect and a method called Execute() which is used to display the error page if the error occurs in another class module. Since Response.Redirect() does not work in a class module, what namespace is needed in order for this to work?
Here is the code I'm using.
In the Catch block.
Catch ex As Exception
Err.Description = ex.Message
ErrorHandler(Err, "function name")
[code]....

I'm writing a program in vb.net 2003 and have come up with a problem.
I have a sub SettingsSave() in a module.
Public Sub SettingsSave()
Dim frmSaveSettings As New frmSettings
MsgBox frmSaveSettings.txtName.Value 'for testing purposes
SaveSetting("MyApp", "configs", "Name",frmSaveSettings.txtName.Value)
SaveSetting("MyApp", "configs", "Pass",frmSaveSettings.txtPass.Value)
End Sub
I have a form frmSettings, which has a button btnSave. When the button is clicked, SettingsSave() is called.The problem is, if btnSave is clicked, then either of the two textbox values are changed, then btnSave is clicked again, the SettingsSave() sub still returns the 'old' values (from the first time the save button was clicked).How do I clear the old values from memory? I've tried adding frmSaveSettings = Nothing, and frmSaveSettings.Close at the end of the sub SettingsSave().

I have a Sub Routine in a module to iterate controls on a form. I get an error about an instance of the object not created.I have declared the object and set it to the form (ModelsBox = Me). I have done this between two forms previously. Is there something fundamental that I am missing. Is this where the "Friend Shared" comes into play?

In a program of mine, I have a resource (which is a textfile). This contains also vb.net code, It is resource which is binded to an .exe, with the mainprogram that I have. So the main program calls the resource, and the resource bind to an exe file.
I have this line:
Declare Function GetProcAddress Lib "kernel32" (ByVal handle As IntPtr, ByVal name As String) As IntPtr
In the source.txt and I want to replace this whole line by a string(or word) which calls this line from somewhere else. For example in another source.txt. A textbox is not possible because this is not a vb form, but a .txt-file. Maybe I can create another resource, which IS a vb.net form, call it or something? In this case. I can create a textbox with this line that I gave above, And I can use it by: textbox1.text.

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()
takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:
Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)
Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

I've written a series of ASP.NET pages which have several common methods among them. In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module. However, what I need is a way to identify from which page was the method called?For example, I have a method call WriteToErrorLog with the following signature:WriteToErrorLog(ByVal sender As Page, ByVal Source As String, ByVal Message As String, ByVal StackTrace As String)

i started with 1 solution, 1 project a usual. Then i did it again, different project. Then, i wanted to have the 2 projects in 1 solution - so i copyed the project folder from solution 2 into the folder of solution 1 and added as existing project the project 2. So far so good.
Now i have a module with some public functions in project 2, that i want to use in project 1 as well. So i added to the solution a class module (some classes i want to share also) and i moved the module, (that i want to commonly use) into this class library. But it seems wrong - my application does not find the function again.
