.NET Solution Does Not Contain A Main Function?
Dec 16, 2011
Every Visual Basic application must contain a procedure called Main.
I Didn't find such a method in my solution..
[Code]...
My problem is, in fact, I try to follow a recommendation that says: Clipboard.GetDataObject Always Returns null? If you find you're always getting null from GetDataObject, try adding [STAThread] before your static void Main().So, me, if I don't find Main()... I can't follow that recommendation in VB.NET...

I'm trying to serialize the main class in my VB solution. I've added the Serializable attribute at the top of my class like so:
[code]...
I'm guessing this is because you can't serialize the form that is attached to the class or something, but I really don't know what I'm doing. Can I serialize all of the objects contained in my Form1 class somehow, without getting this error? I don't want to store any data about the form controls, I just need to save all the objects that I've defined at the top of the Form1 class.

I have taken over support of a VB.Net WinForms application. I am actually a c# developer and am more familiar with the setup of visual studio projects in c# projects. Now I am trying to determine why my application is crashing on a specific XP installation, and I read the suggestion here[URL]..to add a try catch block in the main function. This is suggested in about the 5th post from the bottom. (I will quote it below) However, if I look in the VB.Net visual studio project, I do not find a Main() procedure. What I do find is a grey folder called "My project" with a "Application.myapp" file inside it. This file has an associated designer file, but if I click on it I see the following xml:

How would one insert a Function Main into a VB Windows application? I am trying to return an error code to the command line when this application ends, so that I can check that code through the %ERRORLEVEL% variable.

We generally have main block to start the program or application first form.I wrote some code in main and it is within try can catch block.Catch block the errors. This try catch block is a global try catch for my whole application.Now if exception occur in the code will be handled in this catch. But Is there any good way to handle the exception in the catch block if occur?as I write error in log file but sometimes file can have permissions for writing etc and it can create exception.As this try catch is the outer most try catch block and if any error occur in that catch it will cause application to crash.

We know that the DLL function can be called from our mainprogram and return value. I would like to know, when we run DLL function, can we call a sub in our mainprogram (from DLL function) and return a value to DLL fucntion.

I have a new solution with 5 projects inside. a data access layer, database, 2 class libraries, and the main form. These are all components that I had worked on to get to this point of combining into 1 solution. Now what I have run into is I can not the actual functions in the class libraries. I can get to the class level, but that is it. ere is a sample line of code I need to get working. Once I get this one line, the rest will be obvious: Temperature is on the main form. get for options is "Equals, GetHashCode, GetType", etc... Before this I had bult, compiled, and referenced these classes separately, and it worked fine. I know this is going to be an easy answer, I'm just not seeing it for some reason.

I have controls like buttons, textboxes and all on all the forms in my project, by applying Application.EnableVisualStyles() before Main() Thread starts the controls will have look of XpStyles.
Suppose if i need the Font Size for all the Buttons in my project i need to write the Font Style Property on each form... but this process is very long as my project is big
is there any logic that without writing code on all the forms to update the button Font Size..

I have a solution with more than one project and the main project contains buttons to open forms from different projects that are in the same solution. Say Project1 is the main project and Project2 is the different project that gives the following error when i compile it:
Error 3 'Sub Main' is declared more than once in 'SystemInformation': SystemInformation.Program.Main(), SystemInformation.My.MyApplication.Main(Args() As String) System Information II
I have already seen other threads with this question but it does not work for me because i have more than one project.For Project2: Application Framework is disabled and the startup object is "SubMain".

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:
<script type="text/javascript">
function HelloWorld()

var yourName = $get('txtYourName').value;

I have a solution, Winforms, mainly composed from VB.NET projects (Wiforms, Constrols and business classes).
How, I added to it a WPF project, but wrote it in C#. Actually, every time I make a modification in the WPF C# project, I need to (re)build the C#WPF project. Is there a option to make it work like other (VB.NET) projects (accept and "see" the changes without rebuilding the C# project)?
An example:When I reference project "R.VB" in project "M.VB", I add a method "DoTest" in the "R.VB" and use that method in "M.VB" without compile errors.
If I add "DoTest" in the C# WPF Control and try to use it in "M.VB" project, I recieve a compile error "DoTest" is not a member od "R.C#Class".

I have 2 projects (P1 and P2) in a VB2008 solution, with each project compiled to a separate EXE.P2.exe is started via a button on P1 and while P2 runs, certain aspects of P1 are disabled. When P2 closes, P1 needs to reactivate those disabled aspects.Question: How do I communicate with P1 from P2, seeing that they are 2 separate EXE files, even though part of the same solution?

I've written a bare-bones ap in Visual Studio 2010, Express version. It does what I need and several others are using it successfully. I'd like to add features to it, but I don't want to foreclose the ability to make corrections to the present version.
How do I make a fork in the application for this purpose? Google has been no help in this case, and I've tried several incarnations of copy and change names etc etc.

I recently built a program in VB 2010 that calls an image file from my hard drive. I have found that by deleting or moving the file causes the program to shut down.The code to call the image is as follows:
aTileSheet.LoadBitmap("C:Documents and Settingsimagefile.jpg", 32, 32)
I remember when I was working with C#, there was a way to add a file (such as a Jpeg) to the solution itself.While I can add a file with the "Add Existing Item" command, I am at a loss for how to use it from the solution. If there is some way to add an outside file so that it will be a part of the program after building it, or if this is even possible, I using s dynamicbitmap command (as found from this website ) to use the image. If this effects the results, let me know that too.
