i had some thing challenging work i had three functions
function1()
function2()
function3()
i had a text box and command button i need to execute the functions when the function name is typed in text box suppose i type function1 and click command button the corresponsding function is executed.
I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.
Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag
The following is some code to execute code at runtime: Dim SourceCode As String = txtCode.Text
Dim Dlls() As String = {"System.dll", "System.Core.dll", "System.Data.dll", "System.Windows.Forms.dll"} 'Any referenced dll's

There are two location one main form and other is communication class which use comport to send command.Everything is good in VB6 but same code fails in vb.net actually program behavior is really different.in vb6 one function execute at a time but in vb.net it execute two function at a timeeg. In form there is function to write command over comport once command is posted one event is raised by serial port in this function byte array is formed and the statement immediate next to raise_event use this array to show on formbut when event is raised control is toggle between first function and event function it execute one statement from second(COMMUNICATION CLASS) function and one statement from f
View 1 RepliesIf my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show.

I don't really know why it keep displaying the messagebox that says it failed when I have input the valid strings in the first place.
My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI am creating a form in vb.net and i want its size to change the form as soon as the user inputs the desired number of items. In my form I have two combo boxes: one for number of items and the second is for the choices, then when the user choose 5 items 5 text boxes will appear and if the choice is 25 then 25 text boxes will appear. Is there any way that I can change the form based on the input and number of text boxes?

View 3 RepliesFor debugging I've often thought it would be very useful to have access to the name of the fuction or subroutine that is currently executing so that you could print or display this as the code runs. I've been told by some folks that it is not possible, now I'm asking a broader community. Also, when I asked before it was in the context of VB6, now wondering if VB.Net enables access to the executing function or subroutine name.

View 4 Replieshow to create a function that parses the input from a textinput.Text into an array of named reading, as string, and returns the number of arrays, or perhaps a negative number if there is an error in the input.
i am looking for the answer in vb6 and vb.net.
Trying to imitate a Messagebox - in that, a sub will not continue until the user "deals with" the pop up.
For example, in a sub, I want a Form to pop up, and ask a user a question, and give them 3 options. I want to make it so the user must click an option, and then the sub that called it can carry on it's way.
I believe I need a function to make this happen.
Say I've got the following variables:
Public Shared x As String = "100"
Public Shared y As String = "text"
Public Shared z As String = "something"
[Code]....
But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?

I was once using a program that was under beta, so the creator added a nifty feature. You could enter any vb.net code into a textbox, and when you pressed the button next to it, that code was executed. For example, you could type MsgBox("hello") into the textbox, click the button, and it would run that code as if you actually put it in the source code and ran it. I've googled so many different phrases trying to find out how to do this, but I can't find anything. Anyone have any ideas or resources I can look at?
View 1 RepliesI have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed.
I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.
I have an object with a number of properties (let's say object.one, object.two, object.three). There are about 30 of these properties and they all hold a string ("Pass" or "Fail"). Right now the existing code checks whether the property has value "Pass" or "Fail" and then runs some code that prints stuff out. That is, the same snippet of code is duplicated 30 times, one for each of these properties.
The code looks something like this
If (object.one = ... )
...
End if
If (object.two = ... )
...
End if
If (object.three = ... )
...
End if
I want to use a loop to clean this mess up (each block is huge), but am not sure how to do it. I was thinking perhaps there was a way such that I might be able to construct a string like "object.one" and run some function that will tell the compiler that this is actually an object's property? That way I could create an array containing the object's name like my array = {"object.one", "object.two", "object.three"} and then do something like, in pseudocode
For each string in my array
If (some_function(string) = ...)
...
End If
Essentially, it would take those massive blocks of duplicated code and reduce it to just one block. Is there such a some_function that I am looking for? This is in VB.net.
i want to make a program in which the user can input a mathematical function so the program can then work with it. So the user would input something like x^4+x+2 and then an x and the program would calculate f(x). What i don't know is how to let the user input the function.
View 6 RepliesIn my .NET porject, I have to run a lot of validation on 4/5 fields. This validation checks if certain fields have errors, for example: the name field is not allowed to have numbers or symbols. If all these checks are passed, I need to execute a SQL query to pull some data out of the database. I could have it with a lot of nested IFs, and run the function at the end once it passes them all, but this will translate into about 12 nested IFs, and it seems a really bulky way to do it. I have also thought about setting a boolean value after every check, and if the value is 1 then don't run the function, else do. But of course this gets overwritten by other checks that pass.
