Pass Variable To DLL?
Sep 17, 2009
VS 2008, .NET 2, Win XP I need help with passing a String variable from App to DLL?Why: I have App that on UnhandledException needs to call ErrorReport dll, send to that dll some strings like: App name, stack, error... Dll will send through internet this gathered data to me.
I can open Dll, close it, code it, but I can not figure it how to send data to it like VB App name, VB App version, VB App error.message For example I can in my form make a global variable like Public TestGlobal As String and that I can call from anywhere in my app, but how to do it with dll?
[Code]...

ok to start i know very little about VB6 but i am very good in true basic lol (stupid school teaching the wrong language -_-) anyway im just asking you to make the answer as clear as possible because i don't know very much. heres the problem . ok in the above example i have a button that (for my example) can be used to build a house (lol) i then have a variable in the button sub called money which will have 150 subtracted from it when the button is clicked my problem is it say variable not defined when using this button ... i have declared the variable in a module and in form load along with my other 50 or so variables. my question is how do i pass the variable into this sub and then send the new value back into form load so it can be sent into another sub for more calculations.

I am currently trying to teach myself how to program VB.Net in Visual Basic 2010 Express.I've been working on a little project for a while and have hit a wall. Normally I can find what I need online but I am now at a complete loss. Essentially I am trying to pass a pair of variables from Visual Basic (file names actually) to VBA so that I can copy/paste data from them using VBA. What I need is to find out how I can pass variables (in string form) back and forth between VB and VBA

Dim Elev As Double

What is the best method of tranfering the information from one sub to another.

I have a grid of NumericUPDown fields. When a value is changed, I want the page to update a label at the bottom of a column - its a total line. Everything works, when the page is updated(a button click), but I want it to update real time. as they are changing the updown value... My question, and I have searched and couldn't find it, how do I pass a variable to an eventclick subroutine? Or make the variable a global variable, so it will work in the eventclick subroutine...

I can't find a way to pass a simple variable from my code behind file to the .aspx page.
In code behind I have:
Dim test As String = "test"
and in my aspx page I try: <%=test %>
that gives me the following error: Error 2 'test' is not declared. It may be inaccessible due to its protection level

I have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. A timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form.I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.
Private Sub ActiveMe_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ActiveMe.Tick
If ((WebBrowser1.IsBusy)) Then
Hey.BackColor = Color.Black[code]....
'Error message says Hey is not declared, as i can't pass it through to timer
The variable Hey is determined by the first form - Which picturebox.I have an if statement which simply says if inputbox one has url enter then Hey = Picturebox1, If input box2 has url entered then Hey= Picturebox2 etc.What I want is the timer to check the page has completed loading or is still loading or refresing and the appropriate green or black to be shown aside url input box on first form.I considered using a sub or procedure to act as a clock (a large for loop with another for loop within it, acting as a delay). But found this slowed down theapp to the point of crashing it.

I have a variable that I am trying to get to iterate up by one, i.e. X starts at 0 x+1 on first pass thererfore its at 1 then x+1 on second function call therefore x=2 and so on. I've tried the different loop and for commands but I cant get one to stay until the next function call, does it need to be a global variable? I'm sorry if this is in poor form or improperly formatted, definently trial by fire going into the object oriented world.

I know I gotta get a book or something because things are just way too hard for me. But before that happens I have what I think should be an easy question.
I want to create a variable in xaml, the angle that a control is currently at, and then use this variable in my VB code (event handler).
Or even better can I, while in VB code, check the current angle a specific control is at so that I can add to the number when setting the new angle?

I want to know if it's possible to retrieve the variables name from when it was passed into a certain function. For example, if I call parseId(myId) to a function with the signature parseId(id), i can obviously retrieve the value of 'id'. However, is there any way I can retrieve 'myId' as a string (without passing it as another value)? Specifically in vb.net, but I'm interested in how it would work in any given language.

I don't think I fully understand passing values from a sub to a module. Here is what I'm trying to do (problem is at the '****):

I think I've seen something like this before - where the actual function returns a value. Is this possible? Or would I have to pass an integer variable from the sub to the function, and then return it back to the sub?
