I create a dialog window based on the resource file. I have the following group box:
GROUPBOX "Test group",IDC_TEST_GROUP,50,100,200,200
CONTROL "X",IDC_X,"Button",BS_AUTORADIOBUTTON | WS_GROUP,60,120,20,8
CONTROL "Y",IDC_Y,"Button",BS_AUTORADIOBUTTON,100,120,20,8
I would like to disable group box and all controls. The following code disables only buttons:
EnableWindow(GetDlgItem(h, IDC_TEST_GROUP), false);
EnableWindow(GetDlgItem(h, IDC_X), false);
EnableWindow(GetDlgItem(h, IDC_Y), false);
How to fix that ?
According to the Doc: Group Boxes
Don't disable group boxes. To indicate that a group of controls
doesn't currently apply, disable all the controls within the group
box, but not the group box itself.

So for the simple feat of wanting to put an icon on the right side of button text instead of the left resulted in having to use owner draw buttons (but someone here said Custom Draw is actually available if using visual themes). Okay, fine, but now I'm finding you can't really duplicate what Windows standard buttons do when it's not in owner draw mode.
For a normal enabled button I can get the look correct by checking if visual styles are available or not and then using either the DrawThemeBackground() / DrawThemeText() or DrawFrameControl() / DrawText(). However the hot key underline character is shown even when alt key is not pressed, the default buttons don't show it until alt pressed.
For a disabled button, I can't duplicate the disabled look of the icon placed on the button. I tried DrawState() over DrawIconEx() but that looks like the old Windows 3.1 type grey graphic not the visual style dimmed graphic. I see there is a DrawThemeIcon() for an image list, I guess I could try that (I'd have to test non visual style mode to see if DrawState() matches when not using visual styles).
Also, as you hover over the button, the state doesn't change, I understand that if using owner draw, that doesn't occur, maybe it would still work with Custom Draw?
So the two main questions are:
1 - Is there something built-in to the button / owner draw to handle the underlined hotkey only when alt was pressed?
Update to Question 1: I found DT_HIDEPREFIX in DrawText() and using Custom Draw there is the CDIS_SHOWKEYBOARDCUES flag. However with Owner Draw I'm not sure if there is a flag someplace?
2 - How do you draw an icon for a button that is disabled to match what default buttons do?
TIA!!
For shortcut underline you can use WM_QUERYUISTATE to ask if it should be hidden or visible
DWORD draw_text_flags = ...;
if ( SendMessage( control_hwnd, WM_QUERYUISTATE, 0, 0 ) & UISF_HIDEACCEL ) != 0 )
{
// hide prefix
draw_text_flags |= DT_HIDEPREFIX;
}
// some combination of PBS_DEFAULTED, PBS_DISABLED, PBS_HOT, PBS_NORMAL, PBS_PRESSED;
int state = ...;
DrawThemeText( theme, hdc, BP_PUSHBUTTON, state, text, text_len, draw_text_flags, 0, rect );
Answer to Q2: If you create an HIMAGELIST using ILC_COLOR32 | ILC_MASK, and use ILD_NORMAL|ILD_BLEND25 on ImageList_Draw() it gives the same look as windows default buttons for a disabled button.
Based on responses from #Remy-Lebeau and #Daniel-Sęk and reviewing various projects on CodeProject, I create an easy to use class to handle this. It can be found at CodeProject. Thanks Guys.
Can a combo box be used to set the criteria for a list box? I have a combo box, State, that is the main criteria selection for many of the controls on the form that reside in subforms. I can get those controls to work if they are combo boxes or text boxes, but not in a list box. What I need to do is have the user select 1 of 3 states, then based on that selection, only certain habitats will appear in a list box. I am VERY green and really don't understand VBA.
Except if the Listbox is set to multiselect, it behaves like a Combobox, thus your secret code working with a Combobox will work with a Listbox as well.
I my application, I have added a dropdown box to the standard windows file open dialog. This works fine, but I would like to position this drop box exactly below the file name and file mask edit controls, and its label exactly below the labels for these controls.
How can I get the positions of these controls and the corresponding labels (it depends on the Windows version and maybe even on theming, so using the constants that make the dialog look fine on my computer won't do)?
On Vista+, you should be using the IFileDialog, IFileOpenDialog and IFileDialogCustomize interfaces:
Common Item Dialog
Customizing the Dialog
You can use the IFileDialogCustomize::AddText() and IFileDialogCustomize::AddComboBox() methods to add a drop-down list and its label to the dialog, and if needed use the IFileDialogControlEvents::OnItemSelected event to react to the user selecting items in your drop-down list.
However, you cannot decide where custom controls are displayed when customizing this dialog. UI layout is controlled by the dialog itself:
The Common Item Dialog implementation found in Windows Vista provides several advantages over the implementation provided in earlier versions:
...
•Enables simple customization of the dialog, such as setting the label on the OK button, without requiring a hook procedure.
•Supports more extensive customization of the dialog by the addition of a set of data-driven controls that operate without a Win32 dialog template. This customization scheme frees the calling process from UI layout. Since any changes to the dialog design continue to use this data model, the dialog implementation is not tied to the specific current version of the dialog.
...
The only layout access it provides is the order in which you add your custom controls, and any visual grouping. So, you could use IFileDialogCustomize::StartVisualGroup() to create a new group, then call AddText() and AddComboBox() (in that order) to add those controls to the group, and then finally call IFileDialogCustomize::EndVisualGroup().
On the other hand, when using GetOpenFileName() instead, there are some different options for customizing that dialog, and they allow you much finer grain control over the dialog's layout:
Customizing Common Dialog Boxes
Open and Save As Dialog Box Customization
The preferred option is to create a custom dialog box template and specify it in the OPENFILENAME structure. Within the template, you can have whatever controls and layout you want, and then the template can be inserted as a child of a standard Explorer-style dialog, or as a replacement for a standard Old-style dialog. MSDN documents how to custom-position a template within an Explorer-style dialog:
Explorer-Style Custom Templates
To make room for the new controls, the system expands the default dialog box by the width and height of the custom dialog box. By default, all controls from the custom dialog box are positioned below the controls in the default dialog box. However, you can override this default positioning by including a static text control in your custom dialog box template and assigning it the control identifier value of stc32. (This value is defined in the Dlgs.h header file.) In this case, the system uses the control as the point of reference for determining where to position the new controls. All new controls above and to the left of the stc32 control are positioned the same amount above and to the left of the controls in the default dialog box. New controls below and to the right of the stc32 control are positioned below and to the right of the default controls. In general, each new control is positioned so that it has the same position relative to the default controls as it had to the stc32 control. To make room for these new controls, the system adds space to the left, right, bottom, and top of the default dialog box as needed.
The alternative, without using a custom template, is to obtain the dialog's own HWND directly (which can be gotten inside a hook function assigned to the OPENFILENAME::lpfnHook field) and then you have full access to do whatever you want with the dialog. Microsoft assigned fixed control IDs to the standard controls of an Explorer-style dialog (so you must specify the OFN_EXPLORER flag for this approach to work), and those IDs are consistent across Windows versions. Those IDs are meant to be used with the CDM_SETCONTROLTEXT and CDM_HIDECONTROL messages, but they can also be used with GetDlgItem() to get the HWND of certain dialog controls, in this case the cmb13, edt1 and stc3 controls:
cmb13
Drop-down combo box that displays the name of the current file, allows the user to type the name of a file to open, and select a file that has been opened or saved recently. This is for earlier Explorer-compatible applications without hook or dialog template. Compare with edt1.
edt1
Edit control that displays the name of the current file, or allows the user to type the name of the file to open. Compare with cmb13.
stc3
Label for the cmb13 combo box and the edt1 edit control
Once you have those HWNDs, you can manually query their current positions and sizes, add your custom drop-down list underneath them as needed, and resize the dialog's HWND to accommodate your drop-down list.
Whether you use a template or direct HWND manipulation, you would need to use a dialog hook function to process messages from your drop-down list as needed, such as the CBN_SELCHANGE notification.
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).
Often time I need to add a control to a dialog after the dialog has been generated via dialog template and CreateDialogIndirect. In these cases the tab order is set by the dialog template and there is no obvious way to change the tab order by including a newly created control.
I recently discovered that you can use SetWindowPos to accomplish this. Determine which control after which you want to insert the new control in the tab order then use SetWindowPos like this:
SetWindowPos(hNewControl, hOldControl, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE);
This changes the z-order of controls which, in turn, establishes the tab order.
I know this is an old question but here is how to do it at compile time (which is preferable in the vast majority of cases):
http://msdn.microsoft.com/en-us/library/7039hzb0(v=vs.80).aspx
My favourite method:
From the View menu, choose Tab Order.
Choose Assign Interactively.
Double-click the tab order box beside the control you want to be the
first control in the tab order.
Click the tab order box for each of the other controls.
Click anywhere on the form to save your changes and exit Tab Order
mode, or press ESC to exit Tab Order mode without saving your
changes.
