My program is half a formulator, and half ordering system. Where I get stuck is the ordering system part. In one screen I have 5 check boxes that you can check for which products you want to order. The products you checked then get sent to another screen and put into a list box with a quantity variable that starts at 1 attached to it. Now, if you check the same product again, another time through the program, as of now, quantity accumulates to 2, which is good, that's what I want. My problem is I want quantity to keep accumulating, right now it accumulates to 2, then on a third pass through the program,it duplicates the entry, so now in the list box has the original product and quantity of 2, and another entry that has the product with quantity of 2. 't quite understand how they work. Here's the code:
Option Explicit On
Option Strict On
Public Class OrderRequest
I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables Dim strName As String Dim strArtist As String Dim strPrice As String
I've read through all the search results for this and haven't quite got it yet. I often get given Excel spreadsheets of file names and have to check through them for duplicate names.I am making an app to do this for me. I've extracted the data from Excel I'm just having issues with checking for the duplicate. I've tried 2 different ways I found online and neither are working for me,
How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then lstTeams.Items.Add(teams(i).name) End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams Structure team Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.
I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.
The following solution should allow the user to enter 'colors' to a combo box; however, if the color is already entered (in an upper, lower case or mixed case format), then the 'Duplicate Color' message should be displayed. I get the message, but my color is also being converted to an upper case format in the combo box.
I'm using VB .NET and I know that Union normally works ByRef but in VB, Strings are generally processed as if they were primitive datatypes.Consequently, here's the problem:
Sub Main() Dim firstFile, secondFile As String(), resultingFile As New StringBuilder firstFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "1.txt").Split(vbNewLine) secondFile = My.Computer.FileSystem.ReadAllText(My.Computer.FileSystem.SpecialDirectories.Desktop & "2.txt").Split(vbNewLine)
I am trying to delete multiple selected entries from a listbox. When I run the code I have now, instead of deleting all of the items that are highlighted, it deleted all the items in the listbox.[code]
I've imported data from a text file using Streamreader and populated a listbox with this in 3 columns. I now need to a) get a total value from the 'Hours Worked' column (sum) and b) put in a calculation to populate an extra column for each entry (Gross Pay) where values are not imported but entered as a result of a calculation.
My current code is as follows: Private Sub btnRefresh_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRefresh.Click 'Program Objective: Display payroll report for National Success Coaches which could be updated unknowingly at any time. Dim name As String [Code] .....
I just starting coding in VB.net about two weeks ago so I'm still a begging and I learn best by seeing working code and then adapting it to my situation. That being said, I need help displaying table entries in a listbox. I've successfully created a database in my test application, added it to my Data Sources and used a drag / drop method to add Datagrid View & Details (labels & textboxes) to my application for testing purposes. Now I want to try and display table entries in a listbox.
Also is there any benefit or down side to creating a database in MS Access, create the relationships & tables, then attaching that database to my application or is it better to create the database in the application like I did in the example above by using the Add New - Service-Based Database option?
I have a program with two forms, one that handles the applications controls, and the other with the functions that open a file (csv), open a database, and query the database. The controls on the first form are a list box, three labels (to display parsed csv information), and three buttons (clear database, load database from csv, and load listbox).
The clear database and load database buttons (events) seem to function correctly.On the other hand, the load list box event doesn't function 100% the way I'd want. [And, I can't test the selected index event yet]
The code for the load list box event is:
Code: Dim db As New DBUpdt 'second form b.openConnection("weather.mdb") 'open database connection db.query("SELECT * FROM stations") 'query database Do While db.moreRecords
You see, in my new VB application, I have a form with a TextBox and a ListBox, and I need to make it so that, whenever some text is written in the TextBox, a SELECT operation must be performed in a table belonging to an SQL database, in order to return the elements of a particular column that are LIKE the text I just wrote in my TextBox. The results of this SELECT operation must then be written inside the ListBox.In other words, whenever I have some text inside my TextBox1, I have to do:
SELECT Description FROM Elements WHERE Description LIKE TextBox1.Text (this must be done whenever the text changes)And the results of this operation must be displayed in the ListBox on the side.
Just what the title says. I have a listbox with varied entries, all in one format:name, email, phone, age
When an entry is selected, and when a certain button is clicked, I require the entry to be removed from the listbox and the four categories from the entry must each go into their assigned textboxes.
I have 7 textbox entries and I would like to add them to a listbox and when I close my application it would save them, I have the code for the 7 texboxes and everything like that has been done, but I just dont know how to add multiple textboxs to a listbox then save the list box so when I close the application and reopen it, itll still be there. I know I need a button to add the list to the listbox, but how do I save them, so theyll still be there?
I have a problem that adding a new ROW with duplicate UNIQUE id throws CONSTRAINTException that I cannot always catch.. Randomly general exception halts my VB software, sometimes catching works. here is my code.
I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.
Here is an example of what I am doing:
LISTBOX VALUES 2 2 3
[code]....
When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like
I am being forced to us Option Strict in my class and this is a new feature to me. Right now my code is having trouble comparing the current time to be added (A Date) with the list of times (Object). Here is my complete code
Option Strict On Public Class schedulebookForm ' handles Add button user event Private Sub addButton_Click(ByVal sender As System.Object, _
[Code]....
Problem is inside TimeTaken Function, inside the For.. Until. Basically the If... Then Statement. I tried. .contains, Select Case, and a few other alternatives.
I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
I am making a Bingo game. I have a button which keeps on calling numbers which are then added to a list box. How do i make it that the numbers called don't repeat (get displayed in the "number called" label). Is there a way to use items already added in the list box to eliminate duplicate numbers.
I'm trying to add a string to a listbox if there is none exact string existed inside, but it turns out a very weird error. Look at this. On form_load, I have this: AddHandler Server1.OnUserLoggedIn, AddressOf HandleUser
And then, Public Sub HandleUser(ByVal username As String) 'Here, you handle adding the text to a text box. Me.Invoke(New PrintMessageDelegate(AddressOf AddUser), username) End Sub [Code] .....
The output is when I connect the first client, it works fine. But, when I try to connect the second client, it prints out three times both the listbox1 item and the txtDisplay. It's like get caught in loop, but I have tried other kind of loops like for each and other string comparison too, still work that way.
I want to vary a textbox's name using a variable. for example:
Dim IndexInteger as Integer Dim TextBoxNameSrting as String Do Until IndexInteger =12 IndexInteger +=1 TextBoxNameString = "TextBox" + IndexInteger (TextBoxNameString).text = IndexInteger loop
obviously this code doesn't work with (TextBoxNameString).text but it gives you an idea of what I'm trying to do.
Is it possible to have a datagridview on a datarepeater contol and, if so, heave the datagridview bound or filtered on two fields in the datarepeator, one of them an integer (an id) and one of them a date?
I am working on a custom control and i have it working for the most part, but what i want to do now is, on the form that i put my custom control, i want to fire an event when my custom control gets focus. so what i did was just added an eventPrivate Sub CustCont1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles CustCont1.GotFocusthe problem is, is that when i put a breakpoint on this line i never hit the breakpoint. is there something special i need to code in my customcontrol to fire the gotfocus and lostfocus events?
I have a textbox in a tab control and iv'e coded the textbox_leave event to show a msgbox and reselect the textbox if the text doesn't meet certain conditions.
Private Sub TextBoxChaseTime_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBoxChaseTime.Leave If IsDate(Me.TextBoxChaseTime.Text) Then Me.TextBoxChaseTime.Text = Format(CDate(Me.TextBoxChaseTime.Text), "hh:mm")[code]..... (Reselecting the textbox is the only way i can find to efectively cancel the leave event - is there another)
I've also added a line to also reselect the tabpage incase the textbox_leave event was triggered by selecting a different tab in the tabcontol.However, when the textbox_leave event is triggered by the user selecting a different tab the textbox_leave event seems to be triggered several times displaying the msgbox four times.why this is, but it seems to be caused by the by the line that reselects the tabcontrolhow to stop the msgbox being shown more than once Interestingly, if i add a line to change the text in the text box to meet the conditions the msgbox is only shown once, but the tabpage is not reselcted
when adding picture to dynamic picturebox from my.resources in .dll a duplicate semi functional picturebox is added too, behind the picturebox i intended to add. has anyone seen this happening before or can provide any insight into this?
I have a (COM Interop based) ActiveX contol that I am trying to use with registration free com. When the control loads the control is inactive (does not responds to events, control not fully rendered etc).After much search I discovered that COM objects using reg-free-com use the miscStatus attribute to set the initial state to get correctly activated. I know how to use it with a comClass which corresponds to a native COM Object.
[Code]...
2) The COM client I am using is Visual FoxPro. If the (1) is not possible what can I do in VFP to activate the inactive ActiveX control. (I dont mind VB or C# input too if I can use it to find the equivalent foxpro)Currently I tried the following
But I the OleControl1 gets focus before passing events like mouse click to its subelements. So I have to click twice on it to do the necessary action, any time it does not have focus. I would like the control to act as if the "nouiactivate" of the miscStatus value is set.
3) Is there any other way of accomplishing what I want to do?
