Set A Variable , Say Flag=1 When A Button Is Clicked?
Jun 11, 2009
I need to set a variable , say Flag=1 when a button is clicked.
How do i set the Flag=1 and this variable can be used in OTHER application? Meaning this Flag is set in Program A, then Program B will use this variable (always updated value). I wrote application in VB.NET.
I think app.config isn't that good (use the add key="" value "" ) because when program is executing, it will lock the app.config file.
This Flag variable will be changed according user input (button click) and i try to make this variable use across other application. How to do this?
Is it possible to detect when any button on a form is clicked and then store that buttons name in a variable?
My reason for wanting to do this is because i have over 700 buttons in my form and each one needs to do something different. I want to create one sub with if statements to respond to all button clicks.
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?

with a college assignment. We are to make a program for a school class. It is on Flags of Europe. A Picture Viewer should show a flag and the students must type what the flag is in a text box. If it is correct it must say so in a label and display the next flag. I want it to add the correct answers the student got out of 10 flags.
I have numerous buttons on a form, one each to select a playing card (52 buttons). When the Card(button) is selected I want to highlight it by changing the border from black to Red, then if reclicked from change back from red to black, easy enough (if then else). So that I do not have to copy this code 52 times I wanted to create a module as follows:
Sub ChangeButtonBorderColor(ByRef ButtonName) If (Equals(ButtonName.BorderBrush, Brushes.Red)) Then ButtonName.BorderBrush = Brushes.Black
How to make a link button visible after another button has been clicked in asp.net(vb) in button_click()
it says error as "Object reference not set to an instance of an object."

Protected Sub InsertButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Dim receipt As LinkButton = FormView1.FindControl("LinkButton1") ' receipt.Enabled = "true"
I have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.
i have a form with 10 designated slots for letter to be entered (Like the free letter spaces on hangman), above these are 10 adjacent labels with a full stop "." as the text value, now i have created a button, Q to detect whether there is a. in the first box, and if there is enter the letter Q (Letter1.text = "Q"), elseif check the same for the second box. Now my problem is when i click the button, it still does nothing and letter 1 remains "." instead of "Q". also how would i end this string of else ifs? as in what if every text box is full then do what?
I am developing an application in which there are more than one buttons and i want to add some code on the click of every button, But I wished to know that which button has to be clicked by the user and after that some code will be executed and that code will be different for different buttons.
I was trying to finish up a VB.NET class library project when I tried to remove all unused references. I know for a fact that I'm not explicitly using any thing from the System.Xml and System.Xml.Linq assemblies yet the "Unused References..." button never flags them for removal.In fact I even tried "Unused References..." on a blank project and it still never flagged them.

My btndisplay cost works, but my btnexitprogram does not close the application when clicked. I've ensured the button is correctly named and enabled. But when I click it does not close out, I use this simple code in other programs and it works.
I have a calculate button that, if clicked more than once adds the total of what I previously had to the new total as I am using a loop. I was thinking that I could get around this by only allowing the button to be clicked once, and if the user attempts to do this more than once a messagebox will appear saying that you can only calculate the price once and the form resets but i can't seem to get any code working.
how can I get this .bat command to run after my button is clicked I can make it like, "Run a certain .bat when button is clicked" , but I don't want that because people can go inside my .bat and hack my IP. So I was wondering is there a way I can put that .bat command into my VB 2010 Express
