VB - Form With Fairly Large Number Of Controls - After Curtain Number Of Buttons - Stops Responding To More Radio Buttons
Jan 17, 2011
My VB application is behaving strangley. I have form with fairly large number of controls. I am using case against radio buttons. after curtain number of buttons, it stops responding to more radio buttons.
Then I tried to split controls in to 2 form but now my form.showdialog() too now working properly. It takes new from names but show the old form when running.
I'm using a dialog form with two buttons and two Radio buttons.I'm oppening this Dialog when a button is clicked on the parent form.My situattion is when the Dialog opens the code in the button event continues to execute, but I only want it to continue to execute only after a button from the dialog form have been clicked
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click If multipleEXT = 2 Then Extension.Show()
I want to print a fully decorated form having radio buttons,combo box,checkbox and so many other controls with vb 2008 in a A4 sheet, I dont want to use print form utility given in power pack since the print resolution are very low.
I want to place a few buttons on my form.The no. is unknown at design time.Actually each button will represent an item entered in combo box. So if use adds an item, a button on the form should be added by the code. Please advise how to do it?
I wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.
but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events! better way to replace the html with suitable asp.net web controls or from the codebehind and output it.
There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

I want to put two different groups of radio buttons on my form. How do I specify which button is in which group? I don't know which propert to change.At the moment VB assumes that they are all part of the same group.
I am using Visual Basic 2005 Express. I have previously worked with VB in MS Access, where you can put a frame around groups of radio buttons, but I can't find any such control in 2005 express.
I am currently working on an UI form using Visual Studio 2008 - Visual Basic .Net what i find weird is that when i tried to execute my form using the button click function, it doesnt execute until i restart the form.
Here's the situation is like:i have an openfiledialogue [Open button click] to search for a file.After DialogResult.OK is executed, the textfile chosen will then copied to another working directory. The file name will appear onto a textbox1 There will be more than 1 textfile chosen.After all the relevant files are chosen with the file names on textbox1, an OK button click will be clicked to write the file name into a *.bat file.BUT before the OK button is clicked, the user have to select from the radio button which category they want the file name to save into. EG: Country, Cities, Period.Once the radio button is selected and the OK button is clicked, a .bat file will be saved into the working directory.The next move will be the crucial button which is what this UI is created for. A data CRUNCH button is created to execute the .BAT file which was generated earlier on with the [OK buttonclick].The command used
I've written a program that brings up a form with some radio buttons for the user to choose.The form is setup by a sub in module1 (called Type2Q, shown below). For some reason, often radiobutton1 is checked when the question appears.I specifically set checked to false since I did not want this to happen. [code]
I am trying to code my pet age calculator form to allow user interface for the user to choose feline or canine, choosing the ok button will then invoke the frmCanine or frmFeline, can anyone work with me on this?
Public Class frmPetCalculator Private Sub rdoCanine_checkedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoCanine.CheckedChanged
If a Form contains 2 Group Boxes each containing 3 Radio Buttons and the Form itself contains 5 Radio Buttons not in either of the Group Boxes how many Radio Buttons can be checked at any one time?
i want to create buttons at runtime using vb.net. In my form have 1 textbox and 1 button. at runtime when we input number in textbox than click ok, the button will create follow in textbox and this value it remeber when we run again the buttons will load follow the last number in textbox, when we input new number in textbox it compare small or big than last value. if big add. for location like this
so I have a game in VB 2008 and 21 options for a something in the game and all 21 options have the same code but the number is different. for example: timerX.enabled = true where X is the number from 1 to 21. Is it possible to link them all to one Sub instead of 21?
I am making a calculator of sorts, and have two columns of radio buttons, both running down vertically, next to each other. I'd like to make a simple line that seperates them, serving no purpose but to make the form look a bit more use friendly. How would I do this? All I want is a straight line, but I can't find out anywhere how to make one.
I need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.
trying to write a simple form for calculating professor's salaries depending on their degree and position.my problem is that the when i select a check box, the value is not being updated until i select a different radio button. it probably doesn't make much sense here,
Public Class frmMain Private Sub optLecturer_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optLecturer.CheckedChanged[code]....
the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:
I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
I have a lot of buttons on a form (144) that need to be removed. All their names begin with "R". So I used this piece of code.
Sub RemoveBookingButtons() Dim cntrl As Control
[CODE]........................
However whenever I run this sub function, it deletes every other button starting with "R". better code or point out if the flaw is in that piece of code or it is hidden somewhere else in my program?
im trying to add two radio buttons together to get a full price, they are split up by two group boxes. Meals and dormitories, I have the prices on how much they are, but I dont know how to put the right radio buttons in the right places and then add them up, here is the code I have so far
Public Class Form1 Const decRadioButtonmichigan As Decimal = 1500.0 ' this is suppose to go in the dormitories group box
This is what I would like to achieve:To create a custom messagebox, with varying number of buttons with custom .Text descriptions, and other features. I intended to have a property array that would be redim-ed and have values (.Text values) set by the calling class:
I have a need to add 16 radio buttons to a groupbox but I want to be able to select 2 radiobuttons per groupbox. (2 vertical columns of 8 radio buttons each) The radiobuttons are created dynamically and each set of eight have different names to distinguish them. Do I really have to create 2 groupboxes and put each set of 8 in each groupbox and put those groupboxes into my parent groupbox? Is that it with radio buttons...if they are all in 1 groupbox then there is no way to select more than one at once?
I'm having issues with my current homework. I've got 6 different radio buttons and depending on which one is checked, the corresponding price shows up in the text box. I'm not sure if I need to create a sub-procedure or what. I can't seem to get anything to work.
[code]...
I've gotten this far with the code but not sure where to go next.
I've figured out how to run through the radio buttons and save their checked status to a text file. Now Im trying to recheck them according to the value. Here is what I have.[code]...
Is it possible to create a list of radio buttons similar to that of a checked listbox?And the list of radio buttons should be able to be managed like that of a CheckedListBox?
