Any hunk of code that loops trough the windows form controls array, and based on top/left to bottom/right, resets the TabIndex property? I've mashed a huge form together and expect my user community to want to move things around, and I don't want to have to fool around with this over and over again.

If you have a Component (or Control) with a public property of type Control, then in the Properties Window you automatically get a drop down of all the controls on the same form as the component, which is very handy. If you want to do the same thing but with an array of controls then the Properties Window shows the ellipsis and you get the Collection Editor with the Add / Remove buttons creating and deleting an instance of Control (i.e. the base class used for deriving all the others) - not quite so handy.
How do I get a list of the controls on a form and be able to select more than one? I think I need to create a custom UITypeEditor? Assuming that's right then I think I need a dialog box (like the Font dialog) with Available and Selected ListBoxes with Add / Remove buttons and appropriate code to link the control array in the component to changes in the Selected list box? Along with an appropriate UITypeEditor derived class.
Assuming that's correct, how do you get a list of the controls on a form at design time? Can I do that form design as a Windows Form, just as normal, or is it all done by hand? I've seen some code that does it with a UserControl rather than a Form, presumably that's for when you want a 'pop-up' control (like the one for Color selection)?
I am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.
First of all I want to thank "codeorder" for sharing me this code. Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

Once the Print Button is clicked, the form textboxes clear as intended, table data appended - ready for the next report data entry.
However, I would like to have the cursor return to the 1st textbox on the form which is assigned TabIndex number 1. (without re-loading the form)
How can I add a new property to a button or a form or any thing else in the properties window?

View 2 RepliesI have a form with a tab control, containing a small number of tab pages. I'm writing a sub procedure to clear the controls within a groupbox for the selected tab. A selected tab will only ever contain ONE groupbox and within a groupbox will be command buttons, labels, text boxes and possibly a combobox. The first block of code below firstly finds the groupbox within the selected tab. The next part loops around all control type and if of type texbox clears the text.
Now hears the head scratcher/confusion it error's with :-

What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.

View 4 RepliesI 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.
