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 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?
I have the following radion button in VB.NET
<asp:RadioButtonList ID="rbedit" runat="server" RepeatDirection="horizontal" >
<asp:ListItem Value="1" >Yes</asp:ListItem>
<asp:ListItem Value="0" >No</asp:ListItem>
</asp:RadioButtonList></td>
I need to figure what button the user clicked on and then set a variable with that value.How would I go about doing this?
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?

Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?
I have a combobox, which I use to store the ComboText as well as the number of times that particular word(s) was clicked on inthat session. The code I use for the Combobox looks like:

The problem is, once it has found a duplicate item, it stops counting.What I'm trying to say is, it finds ASP 2 Advanced as a duplicate, with its "click time", it finds Dreamweaver Advanced as a duplicate, but doesn't find its "click time"I need to find the items, then add together all their respected click times, for example: ASP 2 Advanced has 5, then 2 So the total must be 7 Dreamweaver Advanced has 1 and 1 so the total must be 2?
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

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.

View 5 RepliesJust wondering if it's possible to store a reference to an object in a variable.
I will elaborate:
[Code]...
Can I store the common operators such as '>', '<', '+' etc., in a variable and then use it when required.
[Code]....
so here instead of directly using > and +, Can I use the variables OP1 and OP2 somehow. May be I can put the entire string from "If..... NUM1" in another variable as text string and then execute that variable.
I have a program where I open files and I store the location as a variable so I can reopen them later on. It works much like MS Word does, where it shows the names on the side and when I click it and open, it will open the file. Mine is a little different because it will store large numbers of file names in a list box because people are usually going to open folders full of files. The initial way I did it had the path name stored in a list box and it would open the file using that path. I decided it was a bad idea and I tried to use just the name of the file. However, I ran into a problem with the code that I was using.
Code:
If its checked, it will open the selected item from the list box instead.
If CheckBox1.Checked = True Then
'for all the indexes of the saved location record of array, if the selected item is found, then open that file
For counter = 0 To SavedLocations.GetUpperBound(0)
[code].....
So as you can see, what I have is it decides whether you opened from the list box or not. If it is not from the list box, it opens it up fine. It adds the information to the list box and stores some information in an array so I can access it later on. If it does open from the list box, then it will search for the file name in the array. If it finds it in the array, it will proceed to open the file using the directory. There is no else clause because it should be finding it 100% of the time.
The error I get is that parameter cannot be null. Filename2 never seems to get assigned, which means it's not finding the value in the array. I've tested and the value is in the array and the values are the same values.
'ValueNow is updated by an external link eg ADO.NET

I have partially coded a project seen below:

'Defining the cost per ticket
Const _cdecticketprice As Decimal = 153.5D

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.

View 10 RepliesI have a file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.
or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.
