I am trying to use the same form for several functions which means I have to change the properties. In order to do this, I was trying to put a select case in a module that could be recalled anywhere in the project.
As soon as I start a select case in a module, I get an error message "Error1Statement cannot appear outside of a method body." Does that require that it be in a form only and cannot be used in a module?
form1 has datagridview, when I click "add new", form2 appears(details view, allowing me to add new records into datagridview on form1). when I click "add new" again, form2 appears again, if I click x times, form2 will appear x times. How do I stop the add new button and all the functions on form1 from working until form2 is closed?
I am new to .NET 4 and VS 2010. I am using VB 2010 and have made a class and need to know how i can access those functions in the class within another form. So there is a function say of XYZ in the class named classes.vb and need to get to it from form1.vb
I am trying to create a function to clear my form. The code is as follows:
Private Sub resetForm() 'Set an integer to loop through the controls Dim x As Integer
[code]....
it works when I set the type of control as textbox but when I try to do the same thing with radioButton and make it's checked proporty = to false I get checked is not a member of 'system.windows.forms.control'
I have this weird issue:I developed an application with a sequence like this login form -> mainform (=mdi parent) --> some functionform (mdi-child)--> report form
The reportform contains a reportviewer and will display different dataset queries depending on the state of some radio buttons which are located on the previous form ('some function form'). When I run the project directly from the 'some function form' (set startup form for project) things work great. The report shows the correct data depending on choices made on the previous form.But....when I run the project all the way from login and mainform it doesn't work. Seems like the choices made on the "some function form' are not coming through to the report form.
I've have found answers here frequently in the past just from browsing. But now I'm completely dumbfounded.
I'm using Visual Basic 2010 Express, on Win7 32bit. My application talks to an Arduino via a virtual com port provided by a cheap Bluetooth to serial adapter. I use a text based protocol that is working fairly well. BUT one method in my code, taht seems functionally equivvalent to the other methods is locking up my whole window.
It does this whether I'm debugging or running the exe.Below are the offending method, and a simmilar one defined above it that works with no problems.
[Code]...
If I comment out the cal to write, everything works fine. Aside from me setting some state bools and playing with button titles in the first method, I can't see the difference as to why one works fine and the other hangs.
I really hope someone has some experience in the SerialPort object and VB that can shed some light on this.I've tried everything I can think of. I thought maybe it was the inline concatenation, so I dim'd a local and assigned the string to it, and passed that to Write. But I have another method that uses inline concatenation that doesn't do this.
I have implemented webbrowser control in my windows application. I have some functions inthe class file. i want to use those functions from the webpage which is displayed in my windows app through webbrowser control..For example say... I have an standalone windows software. Which has a webbrowser control in the some form. Now i would like to create a webpage that can be displayed in the webbrowser control in win app which has some buttons and textboxes. When i click on button in the webpage it should get the version number of that software. I have some other functions that are in the class file aswell.. but dont no how to call those functions from that webpage when a button is clicked or something like that.
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code. For example the function: Membership.FindUsersByName()
I created a class library containing some properties and methods, when I call a specific method that runs a sequence of tests, it reports "out of memory exception". When I take the same code and build a form.exe, I do not get the "out of memory exception".
When you refrence a Function like this one:[code]You may want to be able to get more out of that, like this.[code]So how would I be able to add subs or functions onto a sub or function like that?
I have made quite a good library for calculating Math problems like Quadratic Equations and many other. Now I met a friend, and hes programming a little in VB, and we were thinking if it is possible to import my functions from C++ to his code, so he can call them, when they are needed, so we can make a calculator? How can we do that?
Edit: My friend is using VB.net Edit: My library is organized in free functions.
I am not sure if i am using these in the correct manner. Basically i have an app that downloads a file from an ftp server (i am kinda cheating cos i am using chilkat). Now if i put the code directly in the form i can get it to do a progressbar.value = ... in it['s own sub.What i decided to do was stick my ftp download parts into a dll i created. Created a function within the dll and i have a return on that which returns the message 'file downloaded' or 'no file to download'. But can i return a value to update the progress bar as it goes when the code is contained in a dll? Or am i totally missing the point and how to use dlls?

I'v got 3 functions that I'd like to combine into 1. There is only one line in each function that changes. can think of a few ways off the top of my head, but not sure which is "the best", or "proper way" to accomplish this.
Private Function CheckQuads(ByVal QuadNumber As Integer) As Boolean Dim intArray(3) As Integer Dim x As Integer = 0
We know some functions in dll files and can use them but if we haw a dll file and dont know functions names. is there a way to get the functions name and their parameters

Does VB.net have anything built in for graphing functions? Linear, quadratic, cubic, log, and absolute value functions would be my main needs. I would want to display the functions on a graph whose x- and y-axes both go from -10 to +10, with grid lines.
