.NET Solution Does Not Contain A Main Function?
Dec 16, 2011Every 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...
Winforms - Serialize The Main Class In My VB Solution?
Apr 5, 2011I'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.
C# - Where Is The Main Function In .Net
Aug 31, 2011I 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:

View 17 RepliesHandling Exception In Main() Function?
Jul 23, 2011We 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.

Accessing Function In Alother Class From The Main Form?
Feb 12, 2011I 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.

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I 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.
Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'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

View 1 RepliesCombine C# And .NET In A Solution?
Mar 2, 2012I 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".

Adding And Using A File To A Solution?
Jan 22, 2011I 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.
