Auto-renumbering Control's Control Array?
Jun 21, 2010The situation is like this, says:I have textbox1 to textbox20 to show real-time reading, then textbox21 to textbox40 for other purpose. So textbox1-20 can be manage in group through: For index As Integer = 1 To 20 Form1.Controls("Textbox" & index).BackColor = SystemColors.Window Next The problem is, after some time i feel i like to change the order or add/delete few textbox, then i need to change the control name one by one by entering the name by hands(says if i add a text box then its name will be textbox41, then then For loop wont work, Or I deicided to delete the textbox15, forloop wont work either, then i need to rename them manually.)
Question: If there a ways that create a control array in VB 2008 express edition? which can set the name of Textbox1-20 to ButtonGroup then refer to them by says Buttongroup(1) for textbox1? (which means set a group of control in one name)
How To Find Out If A VB6 Control Is Indexed (control Array) In .NET
Dec 16, 2010I working on a VB.NET project to manipulate a VB6 form using COM Interop. Some of the controls on my VB6 form are indexed and some not, so calling ctl.Index fails on those that have no index. Is there a way to work out if a control is indexed?

The program does not crash or anything, but the picturebox is no where to be seen on the form. How to I make this work correctly?
And is 'Control Array' the correct term for this? or something else?
Get The Index Of A Control In A Control Array?
Dec 26, 2009I populated a form with several progress bars and added a function to handle a click event via AddHandler. The event fires and I have been able to do things with the control using the passed object 'sender', but I can't for the life of me determine what the index of the control is in the array.
Why is that important to me? Because I want to click the control, have a container of textboxes become visible, and populate them with data from the reference in my database based on what control was clicked, and update that data as needed. Making the container of textboxes visible, and even moving it based on the location of the clicked control in the array are all done and working fine. I just can't seem to get the index of the control.
I need to know what entry (progress bar in this case) was clicked. In the function, I can even do things with a select progress bar using something like pb(x).value = some integer, but I'm trying to find out what 'X" is when the click event fires.
Here are some code snippets...
'Populate page 0 of tab control with progress bars
'TimerCount(int) = number of timer instances active in the database
For x = 0 To TimerCount
[code]....
EDIT: I figured out a work around using the 'name' property, but I would still like to know if what I asked about an index is possible.
One Tooltip For Control Array; Not One For Each Control?
Mar 27, 2012I have an application with as many as 625 Textboxes in a runtime generated control array.I add textboxes one at a time in a subroutine.The application ran with no problems until the parameters required more than 256 textboxes at which point it slowed drastically as textboxes were added. At circa 400 Textboxes it died with an out-of-memory condiiton.
The system has 8GB & a 64Bit version of Windows 7.It looks like the tooltips are eating up memory, causing excessive use of virtual memory from Hard Disk & finally causing out-of-memory.I am now running the application with a label which flashes when the mouse hovers. This uses the Handler for MouseHover.Is it possible to get a single Tooltip to function for all the Controls in an Array? I would prefer this to using the Event Handler.

View 2 RepliesGet The Control Array Element In VB?
Jul 9, 2010In one of the vb6 form, we have a parent - child relation controls. The parent side consists of few radio buttons and the child side contains the control array elements. On click of each radio button, the control array elements are refreshed and populated with data related to the option selected. In the existing application, they have made use of "Load" and "Unload" methods for control array elements. The control array elements are created in the design time(which consists of labels, text boxes and button) and are all placed within a panel, which in turn is placed within 2 group boxes.But the problem comes when I have to unload these array elements.
The control array is created in the design time and the loading of each of these controls is based on certain conditions which is decided during run time.
1. Is there any alternatives to show/clear the control array elements other than control.Load(index)/control.Unload(index)?
2. Is there any way to check whether the controls are loaded or not.
Simulate A Control Array?
May 28, 2010Moving some VB6 code to .Net
The VB6 codes makes use of an Array of textboxes and lots of the code manipulates the textboxes selecting the target textbox via the index. This is very good because a small amount of code can reference a large number of textboxes simply by changing the index. To do the same in dot net I'd need a load of code for each box or I'd need to create the boxes at runtime.
But.
I was reading somewhere that it's possible to kind of simulate similar behavior by creating a bunch of text boxes at design time with the usual names names like TextBox1, TextBox2 etc and then referring to them in code like this:-
Controls("TextBox" + n)
Is that possible ? What would be the syntax ?
2-dimensional Control Array With Circle's
Mar 5, 2011I have to make a game "connect four". I'm having some trouble with the 2-dimensional Array that needs to be created in order to play the game. Firstly there is a function which makes rectangle shaped pictureboxes into circleshaped boxes. Secondly there is a method which is supposed to create a 2-dimensional array with circle's but i can't get it to work. When I run it it only gives me 1 circle at the location which i have given it. I don't know how to get it to repeat. Here's the code.

View 3 RepliesControl Array For Radio Buttons?
May 8, 2010I have some experience with VB6 and it was easy to do a control array for radio buttons such that btnSMP(0) and btnSMP(1) and btnSMP(2) were together and if user clicked on btnSMP(1) it was shown with the blck dot on it as selected. If one then changed mind (which seems to be a very common thing) then if user clicked on btnSMP(0) then it was selected and the other one was not.That is not possible in Visual Studio 2008 for what ever reason the higher ups decided. I have read a number of articles now in MSDN about how to duplicate that feature in VB.net code but it seems to be a lot of work and they add in many features I do not have a need of

View 3 RepliesControl Array Of Datagridview Objects?
Oct 13, 2011Migrating from VB6, a control array of flexgrid objects. Obviously flexgrid is not supported by VB.NET, so DataGridView objects have to be used instead. I tried this alternative to placing them in a list.
I have two DataGridView objects which share a lot of code as well as event handlers. They are named D1 and D2 and many properties, such as column headeders etc., are set at define time. The control array is simulated by passing the "index" and selected grid as parameters in subroutines. For example, the routine to fill the grids, is as follows.
