How do I prevent the user from resizing form dialogues in VB6? The dialogues are small and simple and resizing them serves no purpose, so I'd prefer to prevent it than write code to handle it.
You can set the BorderStyle of the form to either "Fixed Single" (vbFixedSingle) or "Fixed Dialog" (vbFixedDouble) at design-time. Either of these will prevent the user from resizing the form.
Fixed Single provides a Control-menu box, title bar, Maximize
button, and Minimize button. The form
will still be resizable using the
Maximize and Minimize buttons, but not
by dragging the edges of the window.
Fixed Dialog provides a Control-menu box and title bar, but
eliminates the Maximize and Minimize
buttons. It is therefore not resizable
at all. (Also note that a form that
contains a menu cannot be displayed as
a Fixed Dialog and is automatically
changed to the Fixed Single border
style.)
See also the relevant MSDN entry: http://msdn.microsoft.com/en-us/library/aa245047(VS.60).aspx
Select as BorderStyle "Fixed Single"
Change the BorderStyle. Toolbox, Fixed dialog or property window should do it I think.
You can set the BorderStyle of the form to "Fixed Single" and If you want to have a minimizable form , set MinButton property to "True".
form border options available in vb6 are
me.BorderStyle = 0 ' – None
me.Appearance = 0 '– Flat
me.BorderStyle = 1 '– Fixed Single
me. Appearance = 1 '– 3D
me.BorderStyle = 1 '– Fixed Single

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 want a user to be able to select item(s) in my CListCtrl and then click on a button to act on those items. But when the focus is lost from the list, the selection is no longer shown, even if I set 'Always show selection' to true:
This happens both in the dialog test facility, and in my compiled application. I use list-mode, and have no icons, only text.
To reproduce:
Create a new dialog in the resource editor
Place a list-view control.
Set View = List in the properties
Set Always Show Selection = True in the properties
Add a button to the dialog
Press Ctrl-T to test the dialog
Select item(s) on the list, then press the button
..and the text is not visibly selected at all. Or is it... I can just
barely sort of see some very very faint selection in my screenshot - I
think. It's so faint I am not 100% certain it's there!
In addition to my comments: well, there you have it - they are selected, and in a different color, but it seems your screen settings are a bit off. Maybe your color settings, a high contrast mode, or the color setting for selected items in Windows.
The gray color in your screenshot is: #f7f3f7 - light gray, so you might have a problem seeing it, depending on the settings.
An interesting and very lightweight tool to check those things (zoom in, see the color values) is ZoomPlus. I use it every day, and there seems to be source code available too.
I have a GUI that contains buttons and one of them calculates a percentage. I have that percentage displaying in a label, but I'd like it to update the percentage ON THE BUTTON TEXT instead of a label.
I've tried but it disables the button once it changes the text. Is there any way to do this?
Yes it is possible to change button text after creation, using GUICtrlSetData().
Affected source code is required in order for described issues to be solved.
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).
Is there a method such that a user can click on the form itself, and in doing so remove focus from whatever object (textbox, combobox, etc) currently has it? Basically, can focus be uniformly removed from everything at once?
Setting the focus to the form itself does not work.
I thought about doing the old "hide a placeholder button behind another object" trick, but I'm really not a fan of that.
Thanks!
In VB6 a PictureBox can get focus, even if it does not contain any control.
In your case you can put a PictureBox with TabStop false, BorderStyle set to 0, TabIndex set to 0 behind every other control but not containing any focusable control and stretch it to ScaleWidth by ScaleHeight at run-time.
You have to put the labels and any windowless control in this background PictureBox too.
This way when the user clicks "on the form" the focus will "go away". With "no focus" Tab key will focus first control (the one with TabIndex set to 1).
When a form is active, something generally HAS to have focus. It sounds like you're just wanting to not "show" that a particular control has focus.
If that's the case, it's going to depend on the controls. Some have properties that control whether or not the specific control "indicates" its focus in some way.
But the built in Windows controls will always show their focus state unless you subclass them
Given this problem. I'd probably put a button on the form , then move it offscreen when the form loads. Make sure it's not a tab stop, but then when you want to hide focus, set focus specifically to the button, make sure the button is STILL in the tab order, even though it's not a tab stop, so the user can press tab while on the button and end up somewhere logical.
Don't have VB handy, but could you simply remove TabStop?
for x = 1 to me.Controls.count
me.Controls(x).TabStop = 0
next
I have a picturebox and a control on a form.
Private Sub cmdButton_Click
PictureBox.setFocus
Exit sub
End sub
The control doesn't change its appearance, nor does the picturebox.
Of course you'll need to add an If-Then clause if you want the control to respond normally sometimes.
