Forms :: Create A ControlArray Instead Of A Non-working For-Function?
Aug 7, 2011My Problem is, that I have some Buttons, Labels and TextBoxes I need to generate after the User told a number of Players. With the Code I'm using now only the last Player will have these Controls working, because they are moved - for example - from Player 1 to Player 3. how to create such a ControlArray The biggest Problem I have is, that these buttons have to have names like "1", "2", "3" and so on (or if it works somehow to read out the Index of a ControlArray the names will not be necessary).
This is the code I am using right now to generate the Controls, but as you see it won't work, because the properties will be changed when the For-Function restarts.What I need is a hint on how to get these Controls/Buttons into a Control-Array and then read out the Index-Number to use them in the Functions that are called.
Public Class Form1
Private btnTestNumButtons() As System.Windows.Forms.Button
Private Sub CreateButtonArray()[code]......

FileClose Function Not Working Properly

Function Key Form Combo Not Working?
Aug 10, 2010I have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.

View 14 RepliesJavascript - Function PageLoad Not Working?
Aug 31, 2011I have the following code which I want to run when the page first loads and then again when an update panel (asp.net) is run. Therefore I need to use function pageLoad() rather than document.ready.
function pageLoad() {
$(".zoomImage").each( function() {

Problem is I can only get this working with document.ready - so therefore not when the updatepanel is run.

Working Function Adding Recursive Breaks It?
Oct 21, 2010I am looping through all folders on the computer in a background worker. Starting with just the C: drive, the function works perfectly I've been tasked with adding recursiveness to this function to loop through all subfolders within each and every folder.
This is the working code without recursive. Startpath is set = "c:".
Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim fs As New FileSystemObject
Dim fsfolder As Folder
Dim subfolder As Folder
[Code]...
EDIT: I was doing some testing and threw in an if check to skip the C:$ folders. Working ok so far and noticed something really strange. It doesn't loop through all the folders in the C: drive. I think it will loop through only the first 2 folders. One is C:Boot so I skip that and the other is C:Dev-cpp. It won't loop through the Program Files, Program Files (x86), or Users.
