I had a look through this forum and other forums but couldn't find what I was looking for. I am new to visual basic and have spent all day trying to find the solution to the following issue.I am creating objects from a class that store information about the user of the program. Each time a user signs up the program, I need the code to create a new instance of the class, creating an object and storing information about that user. The contents of this object will then be saved into a text file.
My current issue which I've been stumped on is incrementing variable names in a string.
Without reading my actual situation, I need to know if you there is a way to do the following:
Code
'Label1 is a label that exists in a userform and this code is entered into the UserForm_Initialize() Dim X as String
[Code]....
The reason for my label1 example above is I believe that using my current methodology- if there is a way to convert a string contents to a variable name, it should do the trick.
i'm dealing with a variable of the type string, in a "select case" code; if the string in it was "5a6-Hor" then some calculatins will be made. the problem is that the value would be "5a6", but the case related wont be applied(the compiler isnt reding it as "5a6"), although i had a msgbox showing the value of the string as "5a6", as was defined under form_load event here is the code:
I want to move a viriable content from one form to the other . and like wise. Lets see now here is the startup form. Public Class startup ok as you can see am making a public shared variable to get the name from the textbox and put it in the var, thats easy already done , now the problem I can't get it to be moved to the other form. (Below the 1st code is the code I use to get the outcome from form1 to form2).
Public Shared playername As String Private Sub startup_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged [Code] .....
I need to remove some content from string. dim id as string ="TabContainerContent1_Basic_MyFirstName" I need to remove TabContainerContent1_Basic_ . The fix is TabContainerContent1, it is under loop so always _Basic_MyFirstName will be changing. I need to get the text after the last _ char.
i have sql 2005 and i want to develop a small program that can access the database and amend a few rows of data. in sql database, i have 1 table and it consist of 3 columns = datetime, type & price. below is example:
Can you create a string variable, that has 3 prespecified acceptable values?I need a variable that you can basically set it to one of three values and nothing else. Basically so you can't fat finger setting the variable in code.
I have an arraylist of strings, one of them looks like this:It's wet out here and [player id=3686163]Ripper[/player] knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
I need to remove the square brackets and the contents of them, to give:It's wet out here and Ripper knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
The contents of the square brackets are likely to change from string to string, and in some case I may have more that one player in that string.
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
Does variable total have to be converted back to string ie..Cstr(total) in order for the result of total to be displayed in the text box txtdisplay? I notice It will work if I convert it to string or If I leave total a double it will still display the result as a double. what is the correct programming practice? [code]
My program asks the user for the location of the database and stores the location in the variable "filename"I then have this:Dim ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & filename
eally been struggling with this one, and i cant seem to find a simple method of doing it...surely there must be one? I have a list of values that i am loading into a variable. I am trying to split that variable by the whitespace that separates each value...the only thing is the whitespace varies in size. eg.
I have a structure named StudentData, it consists of a studentname, an array of testscoresand the student average. There is also an array of structure objects for a total of 6 students. I have the header, column heads, the student names and the averages printing when I click the print page event. I have tried multiple ways of setting this up to get the test scores to print, these are the structure array variables. When I put in the code to process the arrays testscores, I receive a run time error that I don't understand
Ok I'm creating a sql query with a string variable and executing it in vb. The string would look something like: Insert Into Table (vara,varb,varc) Values ('vara','varb','varc') This works fine.
Is it possible to declare a variable using the text of, lets say a string, as the name?If u dont get it im looking for something like;Dim Var + string1 As PictureBox..In the code "Var" is the start of the name and "string1" is the end of it so if string1 was "Hello", the picturebox would have been named VarHello.
While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.
How do I read all the text from a text file and save it as a string variable? For some reason I remembered it being something like this: IO.FromFile.ReadAllText("path") but thats not it.
i am creating a quiz which would be 20 questions for software design students and may use alot of code.my first problem is the score for the test, i know a friend of mine can add up the score but he cant move onto the next thread until you have got the question correct which is sort of cheating, i want to know how you create a variable and make that variable stay in all the forms and add up the score of correct and incorrect answers and come up with a final score for the user in the end.
I am getting the error:"Range variable 'sender' hides a variable in an enclosing block or a range variable previously defined in the query expression."for this
Imports System.Data.SqlClient Imports System.Linq Public Class Form1
[code]....
I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.
I have just started to try to duplicate what I have done in Autohotkeys language.
What I need to do is point to a string variable - I will explain.
I'm reading from my own asci font files that contain big letters made up of characters, used for chat forums: EG.
[a_ch] ___oo___ __o__o__ _oooooo_
[Code]....
What I then want to say is a_ch=letter. But it is in a loop, so I can't do it directly. I want to point to lettername which contains the string of the variable name.
I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
It's become a night mare. All day today I have been trying to tell the hex contents of the bytes in a string. In this case Im attentpting to detect a VBCRLF. In the debugger this in displayed as a " " and thats it no matter how I have to setting set.It makes it difficult doesn't it? The thing is that debuggers are quite capable of displaying adresses, of course this is only relevant to systems that do not change virtual addresses (which Windows does not)only physical addresses.Why is it impossible to see the values of a vbcrlf (0D0A) in a string? This sytem is becoming impossible to use.
