View 4 RepliesMake All Of The Controls Arranged In Windows Form?
Jun 10, 2010I have a windows form that contains a panel (Hosting panel for X number of panels). The hosting panel AutoScroll property is set to true.I need to create X number of a panels each will have (Lable and three Radio buttons) at run time. The panel controls must be aligned.So I created a loop in my form load event to add the X number of the panels on the form. I used the location X and Y to position the controls on the form. The loop work fine until it reach the point where the controls host panel needs to enable Auto Scrolling which cause the added panels to be shifted to right. The shifting happened once the host panel auto scroll becomes enabled.

How To Make Thread-safe Calls To Windows Form Controls
Sep 20, 2011[URL]
In my program, I created a list of a class that contains 5 picture boxes, a button, a label, an identifier, and some other stuff. I've got roughly 65 of these in this list. I'd be stupid to hard code all that in. The identifier is a 2nd way of identifying which specific location I'm working on.
Anways, all this is created at compile time. Works perfectly fine.
I then manually start a background worker that pings a collection of components. Based off the success of those pings, the picture boxes are enabled or disabled. Basically a proactive way to see if a collection of devices over multiple locations are actually working.
It's the background worker that fails because of thread-safe calls.

View 2 RepliesControls Not Return All The Child Controls For The Form?
Apr 15, 2010I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

View 2 RepliesMake An Array Of Different Controls?
Sep 3, 2010I've been making a table control for a few days, and I've got to the point of making it capable of accepting new data. To do this, I'm making it generate a row of text boxes, combo boxes, and date selection windows along the row that you're entering data into.
I've tried using an array of 'control' types and changing them to whatever specific control I need as I generate it. That sort of works. For example, the code under 'Case "Employees"' below will make a combo box display on the form, but 'ControlArray(i).Items.Add' gives an error because it doesn't think that ControlArray(i) is actually a combobox yet.
You might also be interested to know that everything will have to be dynamically generated since the table I'm using will not always be the same (and the Select Case code will eventually be replaced by something that checks for relationships in the database).
Dim ControlArray(NumberOfColumns - 1) As Control
For i As Integer = 0 To NumberOfColumns - 1
ControlArray(i) = New TextBox
