Changing And Keeping The BackColor For Multiple Buttons?
Dec 16, 2011
Using VB/VS 2010 and am trying to provide the user with a way to change the color of the control buttons on my main windows form. I'm starting with the button click event that then calls another sub-form (code shown respectively below).
I was testing with DirectCast as I need to deal with a multitude of button controls (i.e., will have more than the two shown below).
I would like to know how to deal with the following:
1. How do I save the BackColor so when the user opens the form for the first time (or any other time thereafter) the color set earlier appears (the default via properties is green).
2. When I click on the button for the first time and change the color it doesn't change until I click the button again.
I am using the following code to change my backcolor before I print the page.Is there a way to restor the controls to the orginal backcolor they were before I changed them, the reason I ask is not all of them are the default systemcolors.control, so instead of coding each one individually i was hoping for some kind of "REstore" code?[code]....
When I change the BackColor for a Form, and then add new buttons, they have by default the same BackColor as the Form itself. That does not show on my Windows 7 development computer, but when I use the program on an XP machine, all buttons appear the same color as the form.
I correct this by changing the button's BackColor property to ButtonFace, but it is a pain to do it all the time and some times it gets past me and a wrong color button goes into the application.
Is there a way to change how this works so all buttons are placed with ButtonFace BackColor by default?
what im trying to do now is allow the user to change the backcolor on each form if they would like a different color.The application im working on has 6 forms in it.
I'm making a C++ code editor application using VB.NET. I'd like to change the color of the keywords as the user types it. Also I'm looking for a way to highlight some lines of the code.
Is there a way to change the forecolor and backcolour of a piece of text inside a textbox or a rich textbox?
Well i just tried to turn Rows cells that contain the word Yes into green on form load when i put that code into a button it worked but on a form load i didn't work !
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim j As Integer = 0
I need to loop through a gridview to find records that match items in a different table (in SQL). Is the best method to loop through the gridview and call an SQL procedure on every loop to find matching records? Or should I pull the entire sql db into a datatable and query the dataset in my gridview loop?
'find source ID based on make/model/serial No combination. Dim cSource As New clsSource() Dim ds As DataSet = cSource.GetSources()
When I create more than one instance of the same form and I call a method on any of these instances, the code only fires on the most recently created instance. Even when I click a button on that form, it executes on the other form. How can I call these and keep them as distinct objects?
For example: if I build Form1 with a public method called ChangeMyColor and a button to call that method. Then in the main app I set MyForm1 = New Form1 and MyForm2 = New Form1, then call MyForm1.ChangeMyColor, the color changes on the second instance. Even if I click that button on the first instance, the color still changes on the second.
I made an application that searches for an text file and copy it toc: est. But when is find multiple files i cant copy it because it will overwrite the file in c: est *.txt.Is there a way i can copy a file and Keep the origional file name?[code]...
I am building a sort of 'lightweight' Visual Studio, and I'm trying to implement the feature where you can drag tabs to different 'tab groups', viewing multiple tabs side by side.
I got nearly everything working, I show a ContextMenuStrip when you rightclick the tab headers, with the option of creating a new (horizontal or vertical) Tab Group. When that happens, a new TabControl is added dynamically and the selected tab is moved there. You can drag the tabs around inside a TabControl and even from one to another.
The problem now is keeping track of the 'active' tab. Since I have multiple TabControls (not just two, there can be as many as you want theoretically), their SelectedTab properties are basically useless. How am I to determine which TabControl the user is currently working in? Obviously I will always have multiple selected tabs, but only one active tab, in which the user is currently typing, editing, whatever.I need to know the active tab for obvious reasons: many menu and toolbar items act on the active tab for example. A short explanation of my controls:I have one TabGroupContainer control, which inherits UserControl. I have a TabGroup control, which inherits TabControl.I have a Tab control, which inherits TabPage.
The TabGroupContainer holds a collection of TabGroups (to which I dynamically add/remove TabGroups when required). Now I want the TabGroupContainer control to have the ActiveTab property which returns the one and only active tab (out of possibly many selected tabs).The only logical way is to keep track of the tab that was selected last, for every TabGroup.
At the moment, I am doing this:
- In the TabGroup (TabControl) class, I shadow the SelectedTab property (and return a Tab instead of a TabPage). More importantly, in the property setter, I raise a SelectedTabChanged event:
vb.net Public Shadows Property SelectedTab As Tab Get Return DirectCast(MyBase.SelectedTab, Tab)
[code]....
However, it still doesn't work. I soon figured out why: I am checking that the previously SelectedTab is not the same as the new value in the property setter of the (shadowed) SelectedTab property. I don't raise the event when they were the same, and in this case they were the same (as there is only one tab in the TabGroup!).So, I took that check out, and now it seems to work when I click in the text editor.
So one problem remains: the active tab is not changed when you click on the tab header (and not on the text editor). I am clueless as to how I should handle this... I am once again sure there is a simple fix, but I cannot see it. I can click the tab header, and I'm sure behind the hood it responds to this click, but it never raises it SelectedIndexChanged event because the index didn't change but was set to the same value it already had. I cannot override the SelectedIndex property (so I could skip this check and raise the event anyway even if the value didn't change), and the OnSelectedIndexChanged method is not called, so I cannot use that either...
(Currently using VB.NET 2010 Express) I'm trying to make a program, the main of which is file transfer. I'm trying to create a program that will keep files and folders synchronized across multiple client computers. I'm using a File system watcher to trigger events, and Using a simple System.Net.Sockets UDP client transfer (found via google) to transfer commands between it and itself on other computers.
Here's that code (this just sends from one textbox to another over the internet) Imports System.Net.Sockets Imports System.Net Imports System.Text Dim udpClient As New UdpClient(1024) Dim RemoteIpEndPoint As New IPEndPoint(IPAddress.Any, 0) [Code] .....
By this method, I can rename, move, or delete files. I want to implement file transfer, so that whenever a new file is created, or updated, my program will automatically transfer the file to the other computers and update them there.
Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".
I download code from PSC which is written by VS2005 and want to run in VS2008. Buttons are XP style in design mode when i run it buttons are changing to flat style? Why?
how to go about changing the tooltip on 114 buttons. As you can see from the code below I need to change the tooltip information based on if there is data in an array of structures. I tried creating a string of the button name and passing it on but that did not work.
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load Dim tooltipstring As String
Not as easy as it sounds, I've been doing alot of research on this and I just about decided I can't find the answer, The Goal:I want to be able add a single image to a form from a selection of images with the click of a button, this would probably work much better with java but I know nothing about java so I am using vb
Progress:So far I have decided to just try and find way to change the buttons background image to display the image I want, so I set up lots of buttons in a form with the text "+" which simply means add a photo. Now I binded the buttons to a context strip with text saying what image I can change the buttons backgroundimage to.Questions:I need to know how to make the buttons background image change from the click of one of the options on the context strip. Is this even possible?
If i place 20 different buttons on my form, how can i hide them using the for each function or any other function instead of writing the following for each button[code].;..
I have some VB.NET web forms that have multiple buttons (Submit, logout etc.) If I enter data in a textbox and want to use the submit button, if I actually click on the button it works fine but if I hit ENTER instead it appears the Logout button always takes precedence. How do I control this action as most people hit ENTER rather than actually clicking the button?
I have exactly 88 buttons and they all do the same function. So the function is. If OpenFileDialog1.ShowDialog() = DialogResult.OK Then Dim sr As New System.IO.StreamReader(OpenFileDialog1.FileName) button1.text = sr And I need to do that to all 88 button how can i do this without having to do it manually. and how can i just get the name of the file not the path.
I have lots of items on a contextmenustrip, I want to be able to use multiple buttons for just 1 contextmenustrip instead of creating loads of menustrips for each button, here is what I want my code to do
Private Sub ToolStripMenuItem10_Click(sender As System.Object, e As System.EventArgs) Handles ToolStripMenuItem10.Click if button1 is selected and pressed an item from contextmenustrip then Button1.BackgroundImage = My.Resources.Boss_Room end if if button2.is selected and pressed an item from contextmenustrip then Button2.BackgroundImage = My.Resources.Boss_Room end if
I'm trying to draw multiple radio buttons on my form. I've used this same logic to draw multiple text boxes and for some reason, this doesn't work.
For counter As Integer = 0 To rc - 1 'controller name Radio button and properties. Dim dynRadio As New RadioButton() Me.Controls.Add(dynRadio)
[code]....
I have validated that:
rc = 3 and the loop does iterate three times.The values that come back from the db are correct.xAxis and yAxis are placed properly and is the same increment as my text boxes.It's just not giving me three radio buttons for some reason. It only displays the first one.
I have a facebook account that has around 1200 friend request. Obviously I dont wanna go through and click each one. So I figure I would make a App for it. So I have it working, but its going sooooo Slow....I have it, Clicking the first Confirm button then closing IE, Then opening it back up and clicking the next one. I know it would be alot faster if i could keep that instance of IE open and have it go through and click each Confirm Button but I cant figure out away to do it. If I put it in a loop, it will submit the first one, then when it loops for the second time it finds the first one again, and says its disabled. Any Idea of how I can get it to move on to the next Confirm button? Here is the code I got written so far.
i am working on an alarm system software, i am required to blink buttons whenever an alert SMS is received by my gsm modem, after checking for its authentication with the database. The buttons represents the individual units of houses that are armed with a hardware whereby whenever an alarm is triggered, the hardware sends a alert SMS which is received by my gsm modem. The unit under alert represented by the button will start blinking to show that its under alert, when clicked, it will stop blinking to show that the alert is acknowledged. But now i am facing a situation whereby when the second alert comes in, the first alert will be overwritten by it, which is not what i wanted, i want it to be like both buttons will be blinking, not overwritten. The buttons are all created when the program is running, with its text referred to the database. I have placed a timer to do all the blinking. The timer will start after the checking for authentication.
I'm just trying to learn alot of the tricks and such so I'm making small programs and games to just get the swing of things.I'm having abit of trouble with this one, currently. I'm tying to create a form with two buttons. Now, I want to be able to press two keys on the keyboard and have one of the two buttons activate So, instead of clicking Button1, I pressed Control + C and it will say "Comment" and instead of clicking Button2, I press Control + U and it will say "Uncomment".
Public Class Form1
[code]...
The problem I keep running into is that the only way for the buttons to actually work is if they are already selected (Or, the last one clicked will work but the other will not). Then the keycode will work for them. How do I make this work without having to click on the button prior.
How could I can change de back color of multiple buttons (2700 aprox) depending on the results of my SQL Query i know how to doit one by one i just want to doit in another way
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?
