i wish to make something similar to a command-line kind of thing in which one can type a series of words and the program will run the string through a function that splits up the words uses the first word string to find which function needs to be run and makes the other word strings as parameters of the function to run. its kind of like a odd interpreter based scripting language however once this problem is addresed i have a seperate issue.
i then need to output to a new entry on a ListBox that would be named as a parameter of the first function that splits and such that i explained above.
however i do not know of what i can use to input the name of the listbox only then have that add an entry from within the function.
i wish to do it this way so as not to be tied down to the same naming conventions of the list box every time i use it.
in the end i would like to main function to do all of the above and be called simply like this: Comand2Function(inputstring, outputlistbox)
Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?
I have a listbox which on form load generates correctly from a text file like so in a listbox...ex"John Doe, 1""Bob Brown,2"I now would like to search the listbox if it contains either a "1" or a "2" which is does in this case and copy the item to another listbox. The 1 and 2 indicate positions I have a position listbox for each position. So 3 listbos, first one contains the names on form load, 2 other empty listboxes one for position 1 other for position 2...I have tried the following
If xReservationListBox.SelectedIndex = xReservationListBox.FindString("1") Then 'MessageBox.Show("Found It") xSpot1ListBox.Items.Add(xReservationListBox.Items(0))
The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.
If I have a string Metal is hot : Metal length is 5 cm ; Metal is red. I want to get the sub string that is talking about length: hence I want to extract "Metal length is 5 cm".
I have a listbox on a form and when the user selects a value and the listbox loses focus I want to validate the value the user chose. How do I call my function once the listbox loses focus?
I tried using a custom validator but it gives me an object is missing error. Mike
i am trying to create a search function/filter for a list box basicly when i type a letter or letters into a text box i want the listbox items to be filtered so say i have 5 names in the list box as follows:
Currently doing a resistor calculator, have no idea how to make a listbox lists out all the resistor which insert in a textbox. For example, I key in 20 in the textbox, then the listbox will shows all the resistor : "resistor 1, resistor 2, resistor 3.....until resistor 20".
I'm struggling with a thing or two...and i've read some stuff about the backgroundworker but im stuck Basically what i have is a : PUBLIC FUNCTION TEST (path as string) : which at the end of work , adds an item to the form1.listbox. That works quite nice but freezes the app. I've tried using the backgroundworker, the function in the background worker seems to work nicely, the bad thing is that i dont get any results in the form1.listbox.
I know it's possible to read from database and generate them onto listbox but how about listview using call function. here's a sample of what how a listbox is able to read from a database and generate them on the listbox.the listbox is reading from database, how does one make it to read from an active listview.
Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim strConnection As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= luggageb.mdb"
I have a folder with a whole lot of music in it (*.mp3 files.). Now on my form I can play these songs in playlists, and other extra's. But now what I want to finish it, is to create a search function. Here is a picture of my Form. And what I want to add is a Listbox, TextBox and a button.
When I type: "Eye of the Tiger" in the Textbox and click the Button, All *.mp3 files in my folder, and the subfolders, with "Eye of the Tiger" in it, are added to the Listbox (The full name, like: "Survivor - Eye of the Tiger") will show at the Listbox. How can I do this, in an easy way, if possible.
What i am trying to do is call functions from a string that I created The example would be:genoutput is a string I made to concatenate the function calls when a certain combo box item was selected...
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)Handles Button2.Click Select Case ComboBox1.SelectedItem
I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.
Here is my VB.NET function:
CODE:
As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.
Here's the C# version of my function:
CODE:
Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.
I have an XML file with a list of tasks to be executed. One of the elements of the XML file is funcName (function name), which is the name of a function to be executed in my Visual Basic.NET application (v4).I can retrieve the string name of the function, but how do I go about running it? I have two Class files, GUI and DISP.[code]
I'm just wondering how I could have a Textbox, execute "scripts" through it? Like say my Textbox.Text is "MsgBox("test")", how can I execute that function?
I just want to randomly fill the label with text, I'll put some of the code I need to know what to add to get it, I don't need a click event or anyting just the random part.[code]....
I have a class in this class i call a function which should return some string the class connects to an ftp server and list the directory and returns the filenames of the dir.
Code:
Public Function GetFileList(ByVal host As String, ByVal username As String, ByVal password As String, ByVal currentdirectory As String) As List(Of String) Dim oFTP As FtpWebRequest = CType(FtpWebRequest.Create(host & currentdirectory),
[CODE]..........
So this should return all filenames of that directory
like:
Data1.xml
Data2.xml
Data3.xml
Now i have a form with a listview where i want to call this function and get the files of the "olist"
Code:
Return oList
HOW CAN I DO THAT? i mean how would my sub look like on my form where i want to call that function?
I am trying to call C++ function from VB.Net code which returns string using PInvoke, but it is returning only single character.
C function Declaration extern "C" __declspec(dllexport) LPSTR Get_GetDescription(HANDLE) C function Defination LPSTR Get_GetDescription(HANDLE resultBreakDown){
Here is my code for the string comparison function
Public Function CmpKeys(ByVal oldkey As String, ByVal newKey As String) As Boolean Dim cmpText As Integer
[code]....
My question is whenever I compare "alt+ctrl+w" with "alt+ctrl+W" it tells me that both the strings are the same, but as you can see that both of these strings are not equal because it got small 'w' and the other one is 'W', how come both of these strings are equal?
I have Editbox1 and Listbox1..Inside Listbox1 are the items "#FIRSTNAME# " and "#LASTNAME# "How would I go about adding the text in Editbox1 BELOW the item "#LASTNAME# " in Listbox1 ?
