Label.TextChanged Runs On Startup?
Oct 23, 2011
I have a program that has a series of labels. By using Step Into I've determined that the code below activates when a label changes, however, the program is running on the label text that's pre-applied (in the label text form properties thing). I'd like the program to actually wait for a label to change due to input from the user.
Private Sub LblQ19_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LblQ19.Click _
, LblQ2.TextChanged, LblQ9.TextChanged, LblQ10.TextChanged _
, LblQ11.TextChanged, LblQ12.TextChanged, LblQ13.TextChanged, LblQ14.TextChanged, LblQ15.TextChanged, LblQ16.TextChanged, LblQ18.TextChanged
[code]....
This is a snippet of a larger program of course. fncSumQ Double.TryParses all of the Label.Texts, then loops through them summing += style. If I remove the text from LblQ18 then it moves to another. I'd like some place holders so that the user can see what's coming and if some information is missing.The only thing I can come up with at this point is to have a placeholder that would hide if the real label's value changed. Sounds convoluted.

I want to create an application that once installed (this will be distributed software, so there is no point running code that injects stuff into the registry and creates the the auto startup stuff after the install) , runs on start up on windows for all users, and creates a system tray icon. The following is Visual Basic code that creates a registry key entry, is this the way to go?[code]...

Basically I want to have a textbox (TextBox1) that when you enter an area code (ex. 512) that it will return the state (TEXAS) in the label (Label1). One way that I had been trying before was to reference from a text file the array that I am using which happens to be in the format of 512, TEXAS.
Sample -
TextBox1: 512
Label1: Texas
[Code]...
I would like to use this for multiple area codes and have been unsuccessful in getting it to work.

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

I can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.

How do i code an enter event textchanged event to only work when the enter key is pressed?
1. i have a text button that has a value, or a user can enter their own value
2. however when they enter their own value, the total value doesn't changed because they need to press the enter key to validate the event..

I have a situation where I'm allowing users to enter new values into a combo box or selected existing values from the combo box's drop-down list. Is ther any way to tell whether a value was entered or selected? I've looked at the TextChanged and SelectedIndexChanged events and neither will do what I need to do.

I am using Visual Studio 10 and have run in to an issue that I cannot resolve on my own.When debugging one of my forms the app hangs on a text box control with no errors. But only if you change the text, or press the "Tab" key. The text box is in a group box with a range of other text boxes most with the same properties. All of the controls in this group are connected to an access database record, and formatted to accept the same type(s) of input.Here is the code associated with the control;
[/Private Sub MPhoneTxt_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MPhoneTxt.TextChanged
If UpdateCmd.Enabled = False Then

I want to set the TextChanged event in NumericUpDown box,so that when you press a key, it instantly fires the textchanged event.The default ValueChanged event of the NumericUpDown box does not instantly fire the ValueChanged event. You need to first press the Enter key after you enter a number.And I read somewhere that NumericUpDown box also has a TextChanged event.How do I set the TextChanged event in the NumericUpDown box?

I need to know this because I am in a situation that I cannot find a alternative. I am using MaskedTextBox and has a Mask of "__/__/____". Obviously, It's a date format. Now, I cannot get if the MaskedTextBox is string.empty because it is not an empty. I cannot use "If MaskedTexBox.Text = "__/__/____" then " condition also because It never captured. If I used MaskTextBox.MaskFull = false, It gives an error on creating form. So I came up with an idea that would subtitute to TextChanged Event.

I was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?

I have a Textbox on my application that recieves data from another application via a sendmessage call from the other app.
I can see the data being entered in the textbox but the TextChanged event never fires when the text changes. I need to process the data that is sent but since the event does not fire I'm kinda stuck..

I have invoice form bound to a bindingsource and bindingnavigator. In the form I have unit price, quantity and total textboxes. The total textbox text property is set to total.text = quantity.text * unitprice.text in the textChanged event of both quantity and unitprice text boxes. The result is displayed in the total textbox. But when i hit save button on the bindingnavigator it is set to null and not saved to database. [code]When I used msgbox to see the value of total textbox before bindingsource.endEdit() it is the correct value. but after the code bindingsource.endEdit() it is null. I checked the databinding property and it is correct. What is the problem.
