I have a dynamically created tabpage for windows forms. the tabpage is split into two horizontal panels. The top panel should be able to hold up to 4 textboxes like this
TextBox1
TextBox2
TextBox3
TextBox4
There WILL be atleast one TextBox. Maximum is 4. How do I create a TabPage with two panels where the top panel only takes up the real estate as needed(i.e only use up the real estate for one textbox or 2 textboxes, or 3 textboxes or the maximum 4 textboxes) and the rest of the tabpage is available for Panel2.
Adjust the TabPage.height for the count of TextBox instances. Adjust the lower TabPage.height to fill in the remaining space.
Have you looked at FlowLayoutPanel? You can make any control (which a textbox is if i remember correctly) in the panel to break, that is, make the next control appear on a "new line". This property appears in the Property Window when selecting a control inside the panel, I just don't remember the name.

I have a window which shows a table on the left half. On the right half I display properties of the item which is selected in the table. The user can now change these properties.
The properties are represented by different kinds of controls: textFields, sliders, numberSteppers and popUpButtons.
The user can - besides using the mouse - use the tab key to navigate through the UI Elements. When the table has the focus tab will select the first editable item on the right side, then tab walks through the items and after the last item will go to the table again.
When the table has focus and I change the value of a popUpButton or move a sliderthe default behaviour of the API (Apple's Cocoa) is to change the value but keep the focus on the table.
My intuition would tell me that after changing a control element it should have the focus (i.e. become firstResponder). But I checked some of macOS' preference panes and they behave similarly.
In Apple's Human Interface Guidelines I do not find mention of that specific topic.
So my question is:
Is there a guideline or at least best practice an app should follow regarding if a control element like a popUpButton or slidershould get the focus when clicked or edited?
I am developing an MFC dialog based application and when I maximize the dialog, empty space is added to "right and bottom" of controls. This is because controls have default anchoring position set to TOP-LEFT.
I want the empty space to be added to "left and bottom" of controls means all the controls present in dialog need to be at same distance from right and top of dialog. Also, I do not want to expand the size of control.
So, Is there any way to change the default anchoring of controls to TOP-RIGHT?
PS : There are so many controls on dialog and I do not want to change the property of each one. A common method/property for all is required.
Thanks in advance!
I am very new beginner with VB6 and I hope I explain the things right
I want to create form with 2 buttons (the buttons are located on the top form position )
So each button will switch to other form/window/frame
For example
The first button will show window 1 (there I can set only parameters)
The second button will show window 2 (there I can set only IP address)
Please advice if we can do that by VB6 ?
And if yes how to do that ( step by step )
Remark - Similar example but with multiple windows in the same form is the system properties ( right click on my computer and properties ) , the we can see each button will view different window
Create a form with 2 buttons, Command1 and Command2.
On this form, create 2 frames, Frame1 and Frame2. hide Frame2 and make sure to line up both framesso that they are of the same size and located right on top of each other (Top, Left, Width and Height properties must be the same)
Now put this code in:
Private Sub Command1_Click()
Frame1.Visible = True
Frame2.Visible = False
End Sub
Private Sub Command2_Click()
Frame1.Visible = False
Frame2.Visible = True
End Sub
Now each the first button shows the first frame while hiding the 2nd. The second button hides the first frame and shows the seconds. I think this is the simplest way to implement your task.
PS: don't forget to name your objects properly, it's not a good idea to have default names like Command1 or Frame2 - should be more descriptive than that.
It sounds like you are asking about the tabbed dialog control. To use a tabbed dialog control in VB6:
Click Project -> Components
Scroll down to "Microsoft Tabbed Dialog Control 6.0" and select it.
Click the Apply button.
You should notice a new control in the component tool box. If you do not see the toolbox, click View -> ToolBox. This is the same area of the IDE where you first click to add a button to a form. The tabbed dialog control looks like the top tab of several file folders. When you hover your mouse over the control in the toolbox, you will see a tool tip text of "SSTab". Click this control and then draw a rectangle on your form.
By default, this will add a tabbed dialog control with 3 tabs, but you can change this in the properties window. You can now create any control on top of a tab of the tabbed dialog control and interact with the control exactly the same way you would if the control was placed on the form itself.
What you want is called an MDI Form. It's a form that contains other forms.
You can find a full tutorial on them here, but here's the gist of what you want to do:
Set the "MDIChild" property of all your subforms you want to use to True. Disable their minimize, maximize, and resize functions as well.
Create an MDIForm. Disable its AutoShowChildren property.
Add a toolbar to the MDIForm. Add buttons to the toolbar corresponding to the forms you'll be switching between.
Implement each button's click event, to create child form as expected (or switch to an existing one).
I'm working with VB6 and I have one form with multiple tab controls.
When I drag and drop any control in form it shows me this error:
VB6 has a limited number of named controls per form. To add more controls, you can use a control array. That means, give some related controls the same name, then you can access them by name and index number. So instead of OptionAlways, OptionMaybe, and OptionNever, you could have Option(0), Option(1), and Option(2).
Also, if your dialog is very complex and most of its features are rarely needed, consider moving some options to additional dialogs behind an [Advanced...] button.
I'm trying to have a feature to allow users choose two different methods of cost calculation: either they can enter a yearly cost breakdown on a datasheet (2010: $10,000, 2011: $12,000, etc) or they can enter a flat yearly cost multiplied by the number of years they select.
If I were developing another kind of web application, I'd have radio buttons to select two different options. One option would display the datasheet, and the other option would display two text fields to enter values into. However, I understand that you can't have radio buttons in Access 2010 web databases. Also, is it possible to make elements appear and disappear based on a combo box selection?
If not, perhaps I could have two different combo box options: "enter yearly cost breakdown"
or "enter flat yearly cost," which open the correct respective forms as pop-ups.
So, 1) can I have Ajax-like appearing and disappearing elements as triggered by a combo box (or ideally, radio buttons), and 2) if not, can anyone think of another clever way of doing it?
Sure, you get a nice effect by using a tab control. You can place controls and even a sub form on that tab control.
So, you build a screen like this:
Then, simple set the visible property of the second tab = No. This will hide the tab (don't change this until you built the page since it will hide it! (use property sheet to hide/un-hide during development).
Now, add some code to the after update event of the list box. Like this:
In the above, I have named the tabs PYear and PFlat.
The result is this (this is a animated gif I inserted):
Of course, you really probably could just dump the whole "list box" selection, and use a screen like this with the tabs (tabs are good UI, and users tend to grasp them quick):
So, you can hide a "set" of controls, and it really far less work and hassle then writing a bunch of JaveScript anyway. As noted, the "set" of controls you drop into each of the tabs can be sub forms, and also that of continues forms. So, the "hiding" as a set does work well in this case. I did have some format issues and found that I had to "start out" with the 2nd tab dispaled first (the first one being hidden). As noted, the listbox selecting is nice, but one could likly just go with using tabs in the first place.
