Delete Dynamically Created Text Boxes From A Form?
Feb 10, 2012
ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
With the following example of code, whenever the user clicks a menu item it will load up a new form. This form will then read from a database, and create text boxes throughout.
Private Sub allowances_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If mainMenu.currentSlic.ToString = "0" Then
I have a form that has an array of dynamically created labels of varying size based on a search from a database. The problem I'm having is that when the user searches for a different term, it looks like some of the labels don't get new values. Here's my code for adding the labels:
If rdr.HasRows Then ReDim Preserve entities(cnt) While rdr.Read()
[Code].....
I've tried for loop over the controls in panel1 to dispose of any still on there in both the page_load and page_init subs, but neither had an effect. I don't know if it might have something to do with controls having the same IDs after the postback.
I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!
I am adding a grid of buttons to a form at run-time, and all of then use the same Handler.My question is : Is there any way I canadd the TextBox at run-time ?I know how to but without it on the form, the IDE isn't very happy about the "MyClick" Sub - TextBox1 is not declared......

how to move info from text boxes on one form to binding source text boxes on another form. I am displaying array info in text boxes on one form and i need to add them to the database on another form. How do I do that?
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?
I am using VB.NET vb 2008 . I am trying to create text boxes dynammically and remove them here is the code i have written so far
Private Sub setTextBox() Dim num As Integer Dim pos As Integer
[Code]....
I am able to create the textboxes but only a few of them are removed. by using For Each ctrl In Panel1.Controls it doesn't retrieve all the controls and some ae duplicated as well.
I have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?
Now I would like to save this form as .vb file and include it in my project. Similar I have created in PHP where output html and saving as .php file is easy. This I have used as a initialize function as i start doing some project whose database has been created already.
My problem is after I created 5 rows of text boxes, I want to add random numbers to all of the text boxes in one time when I click the button.Here are my coding to create text box dynamically:
Private Sub btnAdd5Row_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddFiveRow.Click For Me.count = count To 5
I find myself copying single files to multiple different machines, so would like to create something to help.I would like a numericupdown, which dynamically adds text boxes (which will be destination file paths). I will obviously need it to remove them too when I decrease the number.
i have a database created in access showing in multi text-boxes in visual basic 2008 express edition. the database is showing music information and sales (tune name, artist, sales, and year issued) there are a few processes i want to do but can not work out the coding.1. display the top ten selling tunes in a particular year in order ( the year needs to be selected from a list box and displayed in a list box)
2.display the total sales in a particular year ( year selected from a list box)3. display the tune with the greatest sales in a particular year ( year selected from a list box)
I am currently developing a simple menu application that has a control array of buttons and I am having a hard time with re-sizing the form and centering the buttons. These buttons are created at compile time (with parameters from an INI file) and my current centering algorithm seems to slightly set them to the right. I am using the "button.location = new Point(...,...)" method but after reading about this it says the values locate the buttons left upper corner rather than center, thus accounting for the slight offset to the right.
My two questions are this: How can I perfectly center these buttons at compile time? I have tried accounting for the difference by subtracting half of the button's width but the button width and point properties seem to be incompatible and the button gets heavily offset.
And... my other goal for re-sizing the menu is to have the buttons perfectly expand and contract when being re-sized. It seems as though anchoring is ineffective when the buttons are created dynamically so I have been forced to write ratio algorithms... Is there a way to get anchoring to work?
Here's what I have in the load up : MyControlArray(i).Location = New Point(CInt(((Width - ButtonWidth) / 2) +_ (ButtonWidth / 2)), CInt((Height - MyControlArray(i).Height) / 2))
I have already tried: New Point(CInt(((Width - ButtonWidth) / 2)), CInt((Height - MyControlArray(i).Height)_ / 2))
The code below shows adding three text boxes using a button, I'm thinking when there's excess of text boxes that has been added, how can I delete the excess using another button.[code]...
I'm designing a windows application in visual studio 2008 and connecting to oracle 10g XE but don't know how to add, update and delete records from my database using text boxes.
I understand that currently vb.net message boxes support buttons like ok,cancel,yes,no,abort,retry.but i am wondering how do i customize my own message boxes such that i can rename the yes,no buttons to any text like delete or discard.
I am using zedgraph to draw bar chart in my vb.net project. The bar base is Y (meaning all bars are horizontal). I have 9 fields for user to choose from, and once a user clicks a field, one corresponding bar will show. Of course, the user can click off the selected field to remove the corresponding bar item. I can do this. The basic idea is to get all bar items and set their visibility according to user's selection. My problems is that I want to have a textlabel next to each bar (this text label is different from legend)so I set the yAxis.Type=text. There are two problems:
1) When I add bars, I still need to specify x and y value. How do I set y value in this case to make sure bar ally perfect with its text?
2) As far as I know, I can add text labels by an array as the last line code shows. But obviously this only works for bar chart with fixed bars. In my case, the number of bars and also the order is changing based on user selection. How can I set text labels? [code...]
I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?
I have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
I have a text file containing 10 pieces of information. I want to read the information from the text file and put it in text boxes on a form, so that the user can view the information and edit if required. What is the best way of approaching this?
