VS 2008 / Looping Through Textboxes, Outputting To String ?
Feb 21, 2010
I have a number of textboxes in my program, and a few other controls with text in them.I want to loop through a select number of textboxes (1-10 in this case, for testing), and output their combined data into a string.Here is what I created, with the help of someone on this forum earlier.[code].....
I have a program with a lot of textboxes.They are all named Textbox[numbers].I have 39 textboxes.I want to take the text of textboxes 1-26, in order, and output their text into the clipboard, with a loop.I do not know how to make it so it only loops through 1 - 26, and make it not include 27 - 39.
i have a textbox where i get numbers by looping...i get 1,2,3,4,12,345,32 and 67.. but i get only 67 in textbox..i want to add all the numbers and display the result at the end...
I am trying to loop through 10 textboxes (TextBox1 to TextBox10), which are located in a Tab (TabPage1), and clear their values.I have written this code which doesn't seem to work:
Dim i As Integer For i = 1 To 10 If TypeOf Me.TabPage1.Controls(i) Is TextBox Then Me.TabPage1.Controls(i).Text = "" End If Next i
i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0 Private Sub ClearText() For i = 0 To Text1().UBound
For Each control2 As Control In GroupBox3.Controls If TypeOf control2 Is TextBox Then Dim txt2 As TextBox = TryCast(control2, TextBox) If counter > totalBoxes Then
[Code]...
What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?
On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls If ctl.Text = "7777" Then ctl.Text = "found the sevens" End If Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls If box.Text = "7777" Then box.Text = "Found" End If Next
I'm trying to make a function in VB.net that will loop through an algorithm. I've split the algorithm into an array using the Split command, so I have an array with the values. I then try to loop through them and replace a # with "Number" where necessary, however VB.net throws an error. Algorithms are in the format A B C D E F 1 2 3 #
Function generate(ByVal alg As String) Dim algSplit As String() = alg.Split(" ") For Each digit In algSplit
how to get an array of string from certain datagridviewcolumn,i try using this code,it doesn't work..
For Each row As DataGridViewRow In dgvPaketRow.Rows If Not row.IsNewRow Then Dim str() As String = New String() {row.Cells(0).Value} Dim strRes = String.Join(", ", modCommon.str) msgbox(strRes) End If
I have been out of the VB game for awhile and am now trying to catch up to VB.NET. I know my current solution probably has a more efficient way of doing what I want, such as using LINQ or something. But, I am start at the bottom and working my way up. I essence I have 1 table controlling which columns get added to a working string, that I will eventually export into a text file. My first table has 3 columns(ID, String, Processed). The ID is the index or primary key and the string is the data I need, and Processed tells me if I have extracted that string yet or not( 0 for no and 1 for yes)...
My main problem is checking values in table 1 where I need to add the string. Of course my problem might be deeper in how I am even returning the values from the datatables.
Code:
Partial Public Class StoredProcedures <Microsoft.SqlServer.Server.SqlProcedure()> _ Public Shared Sub StoredProcedure1()
Is there a way of merging (importing or whatver is the correct terminology is) the data from an Array in to a DataTable woithout looping. I already know how to loop through the array to populate the DataTable with new DataRow but I'm looking for something much faster if it exists. I've got a 1 dimensional String array i.e. 'String()' that I need to populate a DataTable with new DataRows.
I am looping through a word doc where I need to find a string to replace and these are in text box's so I thought I could do something simple like this but its not working. vb For Each oRng In doc.StoryRanges Do strTxt = oRng.Text If strTxt = "textToReplace" Then [Code] .....
I am trying to print (to a text file) the fragmentation information give by Win32_Volume class using the DefragAnalysis method and have come up with the following VB.NET code:
Dim objReader As StreamWriter objReader = New StreamWriter(FolderBrowserDialog.SelectedPath + "FragInfo" + "_" + CreationDate + ".txt") Dim colItemsFragInfo As New ManagementObjectSearcher("rootCIMV2", "Select * from Win32_Volume where DriveType = 3")
[code]....
You do not need to defragment this volume.However executing this in Visual Studio returns the below:
Volume size: MB Cluster size: MB
You do not need to defragment this volume.The point here is though it does NOT work under Windows Server 2008 R2, but does work under Windows Server 2003 (when executed in Visual Studio), WMI Code will work regardless of platform.
NB: i have played with the "Console.WriteLine" and changed it to "Debug.WriteLine" to output value to immediate window.
I have tried running this codes over and over again but i dont seem to be getting any progress, the output is not complete. Its supposed to Display the first Letter of the First name then the secondname followed by the phone no and if a client has more than one record to list down all their records
Private Sub btnSearchrecord_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchrecord.Click 'Retrieve a client from the record Dim Message As String
I'm sure there is probably a better way and certainly a more correct way to do with. But, right now when I output to the listbox, I'm only getting the information from the last item in the array.
Public Class frmInvoice Structure Invoice Dim intNumber As Integer Dim strTitle As String Dim strDescription As String
I'm working on a program that allows me to quickly write database entries. There are 123 columns, almost all of them I'm not using right now so I figured I'd write a program to speed up the process of adding entries to the database.The problem I'm having is exporting every row in a DataGridView to a .sql file. I'm able to do it with a single row but I'm having trouble with doing it for all rows. Every time I get a index out of range exception.I can't figure out why. The problem is probably obvious, but I need a fresh set of eyes to figure it out.In order for it to streamwrite each line it first collects all the data from the columns by using a loop then it writes it, clears the string and starts on the next row, looping for all the data, so on and so forth.
Private Sub StreamAll(ByVal table as String) Dim TotalRows As Integer = DataGridView1.Rows.GetRowCount(DataGridViewElementStates.Visible) Dim CurrentRow As Integer = 1
I am stuck on trying to get the sum of numbers to output to a label. I have a label box lblTcost that I would like to have the total of my list box lstCost placed into there. I have tried several things and keeps crashing or just not working at that part. I have used the debugger but since I know the line is wrong any ways that not helping. I though this line would work lblTcost.Text = lstCost.ToString("c") was the proper way but it isn't. Here is my completed code
Public Class Form1 Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click 'Declare values from both listboxes Dim Day, Fee, Stay, Total As Integer
I have a combo box that has multiple options, when the user selects one of the options (world wide city destinations) a specific value is assigned to a variable. For example if "New York" is selected the variable "x" is assigned the number 155. What I want to do is output the destination that has been selected ie "New York" in a label called "lblOutput1", do I need to store the destination as a seperate variable to be able to produce it in this label as I cannot seem to get it to work:
At the moment I am using:
lblOutput1.Text = "bla bla bla " + cmbDestination.SelectedText + " bla bla bla " + Today()
I've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code:
To simplify my problem, lets say I have 200 textboxes on a form. I want the first 100 to become disabled in a certain subroutine. I don't want to write 100 lines to disable each textbox; I'd rather write a loop to do it but can't figure out how. For instance:
dim i as integer dim s as string for i = 1 to 100
[Code].....
I tried "dim c as new control" then "c.name=s" but I don't think this makes "c" as a member of my form and it didn't do anything as a result. I think I need to figure out how to declare c as a control that exists within my form but can't figure out the syntax for that.
I am making a very small program. I got a form2 and 2 textbloxes and a button (and a label). I want to use the textboxes to change the form1 window's width and height and apply changes on button click. I can't get the textboxes to convert from string to int? I am still learning VB and highschool doesn't teach this stuff. Any help on how to do this? And maybe a free ebook on VB 9 or 10?
I have made this code, which is to update the MySQL db, the only problem is that even though i got try on, it dosnt catch any erorrs, and the code is not working, meaning it dosn't update anything in the db.
code: Private Sub updateSqlData() Dim nSQL As String
How would I go about outputting a listview control with 4 columns and x amount of rows to a text file so that it can be printed? Or how would I go about adding it to a database and printing it?
It's been a while since I have posted. Good to be back. I am doing some scripting work using Visual Studio 2005 Tools for application. I am having an issue outputting to the debug window. My line of System.Diagnostics.Debug.WriteLine("Test") I have the output window open when I start debugging and am using the debugger. What happens is the debug window seems to go away when I allow the line to execute. After the line executes if I go back to the output window nothing is there. The message does not go to the Immediate window either.
