Populate Textboxes And Make Them Visible Once Button Clicked

Mar 10, 2011

I was looking for some better way of coding to populate all text boxes and make them visible once a button is clicked. I have a letter like format on a page with labels displaying address, name etc and it was recommended that on this page some of the information should be able to be edited. The idea I had was to keep the labels displaying the information but then when the edit details button is clicked the labels disappear, text boxes will appear and be populated with the same text as the label to allow the user to edit the details.

I seem to repeating lines of code but changing one thing each time on page load
Dim Sname As String = Request.QueryString("Name")
lblStuName.Text = Sname
tbStuName.Text = Sname
tbStuName.visible=false
[Code] .....

On edit button
tbStuName.visible=true
tbAddress.visible = true
etc..

On the save button
sqlStatement = "UPDATE StuTable SET Name = '" & lblStuName.Text & "', Address = '" & lblAddress.Text
My code seems very repetitive in many parts, I was looking for a better coding style to do this.

Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?

Jun 28, 2010

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

Dim picLight(2) As
Boolean
For intX

PerformClick() Doesn't Work - How To Make It Work

Feb 2, 2011

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:

btnWhatever.PerformClick()

Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

Button On Form - Visible To Invisible?

May 18, 2012

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.

.net - Make All Imports Visible Within A Class?
