[VB6] - Multi-line standard tooltip.
Standard tooltip (property "ToolTipText" of controls) does not support multi-line text and displays all the text on one line. Suggest module that supports "multiline" standard tooltip based on subclassing windows tooltip. Can, in principle, and the color and design to change the tooltip if you wish, I left the standard; You can also add width adjustment (so as not to produce a lot of code I left centered), commented on almost every line. Button to stop the project after the launch of "hook" can not be otherwise crash IDE (I have Win7 (64), not falling apart; always took off on XP), it is necessary to close the window and call "Unhook".

Re: [VB6] - Multi-line standard tooltip.
I tried few methods either by a resource file or manifest, but I can't get themed tooltips. Are you using hard code to draw tooltips?
Code:
Case WM_PAINT
BeginPaint hwnd, ps
md = GetBkMode(ps.hdc)
oft = SelectObject(ps.hdc, hFont)
SetBkMode ps.hdc, TRANSPARENT
DrawText ps.hdc, s, Len(s), RC, DT_WORDBREAK Or DT_CENTER
SelectObject ps.hdc, oft
SetBkMode ps.hdc, md
EndPaint hwnd, ps
Exit Function
Re: [VB6] - Multi-line standard tooltip.
Once you're doing drawing yourself like that, shouldn't you simply be able to use the Theme API? Mainly the DrawThemeBackground function...
Code:
TOOLTIP TTP_BALLOON TTBS_LINK, TTBS_NORMAL
TTP_BALLOONSTEM TTBSS_POINTINGUPLEFTWALL, TTBSS_POINTINGUPCENTERED, TTBSS_POINTINGUPRIGHTWALL, TTBSS_POINTINGDOWNRIGHTWALL, TTBSS_POINTINGDOWNCENTERED, TTBSS_POINTINGDOWNLEFTWALL
TTP_BALLOONTITLE
TTP_CLOSE TTCS_HOT, TTCS_NORMAL, TTCS_PRESSED
TTP_STANDARD TTSS_LINK, TTSS_NORMAL
TTP_STANDARDTITLE TTSS_LINK, TTSS_NORMAL
TTP_WRENCH (Windows 7) TTWS_NORMAL, TTWS_HOT, TTWS_PRESSED

Re: [VB6] - Multi-line standard tooltip.
Trick,
I run 64-bit Windows 10. I can't get your sample program to work correctly in the IDE. It works fine as a compiled EXE but in the IDE each of the tooltips flash once and then don't show. But even stranger, the one string S(2) in your form load that has 7 lines of text sometimes displays and stays displayed but none of the others ever remain displayed. Is this intentional?
Also, I am guessing that the comments in your code are in cyrillic but since I don't have that as an ANSI code page I can't translate them. Would it be possible to save your two code files in UTF-8 so that we can see and then translate your comments? Thanks.
Re: [VB6] - Multi-line standard tooltip.
Hi, MountainMan
I've translated the sources. Please try to run and tell me if the error still happens.
Thanks.
Re: [VB6] - Multi-line standard tooltip.
Thanks for the comment translations. However, I am still getting the same performance of the tooltips in the IDE. the 7-line one generally stays displayed but the others just appear momentarily. That doesn't happen when executing the program outside the IDE.
Re: [VB6] - Multi-line standard tooltip.
I Made this changes to remove the limit of the 255 chars size and to create a newline with "///" so multiline tooltips can be easy edited from the designer window.
Added code in Bold:
Code:
' Tooltip window proc

If l Then ' Check for empty stirng
s = Space(l) ' Allocate enough buffer
lstrcpy ByVal s, ByVal lParam ' Copy string to buffer
'Get the full tooltip text from the control
If (Len(s) > 254) Then
s = GetFullTooltipText(GetForegroundWindow, s)
End If
'Allow to type newlines easy in the property windows directly
s = Replace$(s, "///", vbNewLine)
bw = GetSystemMetrics(SM_CXBORDER): bh = GetSystemMetrics(SM_CYBORDER) ' Get border sizes
dc = GetDC(0) ' Acuire context to calculate string boundaries

Re: [VB6] - Multi-line standard tooltip.
With The Trick's approval, I have made the following additions to his code:
- All Windows API calls are Unicode.
- Added shagratt's suggested addition (post #8) for removing max length of tooltip.
- Added shagratt's suggested addition (post #8) to use /// in tooltip to denote a vbNewLine.
- Changed public procedure names: Hook to ToolTipHook, UnHook to ToolTipUnHook to avoid potential naming conflicts with other modules.
- Made module-level variables private to avoid possible collision with variables in other modules.
- Added public variable MLToolTipsOnlyIfCompiled that, if True, restricts the use of the hook to non-IDE (compiled) programs.
- Took out alias for RtlMoveMemory and switched calls to CopyMemory to RtlMoveMemory (personal preference).
- Changed capitalization of some variable names.
- Changed variable name lpPrev to PrevWinProc (made more sense to me).
I haven't worked on theming yet (see posts 2, 3 and 4) but when I get some time I'll add that.
Re: [VB6] - Multi-line standard tooltip.
I like to use this to complete Krool's work to make my app fully Unicode supporting. However, both compiled and in IDE the Unicode text that has been assigned to the tooltips shows as questionmarks only. (I tried with Russian and Thai on XP and Win10. Standard VB6 toolbar, and Krool's CommandButtonW.)
Do I need to do something special when assigning the Unicode texts to the tooltip properties?

frm files stores all the string properties as ANSI. Please attach a small example.

Re: [VB6] - Multi-line standard tooltip.
OK, a bit more background:
The Unicode texts are read from an UTF-16 file at runtime, and stored in a Class/collection.
When a form is opened, the translated texts are assigned to each of the controls on the form. Here is part of the code that handles that:
Code:
With g_oTranslationCol.Item(i)
If .Index = -1 Then
'Form, replace caption
DefWindowProcW oForm.hWnd, &HC, 0&, StrPtr(.TranslatedText) ' &HC = WM_SetText
ElseIf .Index = 0 Then
'Single control, replace caption
If (TypeOf oForm.Controls.Item(sControlName) Is Menu) Then
'Skip
Else
oForm.Controls.Item(sControlName).Caption = .TranslatedText
End If
ElseIf .Index > 100 And .Index < 1000 Then
'Toolbar control, replace tooltip texts of button; remove last 3 characters used to make control ID unique
sControlName = Left(sControlName, Len(sControlName) - 3)
oForm.Controls.Item(sControlName).Buttons(.Index - 100).ToolTipText = .TranslatedText 'buttons array starts at 1, so no correction is needed
ElseIf .Index > 1000 And .Index < 10000 Then
'Tab control, replace tab-captions; remove last 4 characters used to make control ID unique
sControlName = Left(sControlName, Len(sControlName) - 4)
oForm.Controls.Item(sControlName).TabCaption(.Index - 1000 - 1) = .TranslatedText 'tab array starts at 0, so correction is needed
End If
End With
Using Krool's Common Controls Replacement objects, translations are applied without any problem to controls, but the tooltip only shows questionmarks. See picture. (Note: two screen captures combined in one picture, as the tooltip is not displayed when the dialog is open (in vbModal mode).)

Re: [VB6] - Multi-line standard tooltip.
I could not make display Unicode to any of the two projects, I get all question marks.
I think when you assign a text to the VB ToolTipText property of an Extender, it must be converted to ANSI, but I'm not sure (since you say it works).
Test project attached, with some Chinese text.
This issue of the tool tips seems to be a stopper for full implementing Unicode with Krool's controls.
Re: [VB6] - Multi-line standard tooltip.
I didn't like this tooltips routine for several reasons including quick show/hide. I wrote a better class module that does unicode here.
Re: [VB6] - Multi-line standard tooltip.
OK, my question was quite some time ago, and at that stage I was experimenting with Unicode to figure out how to best deal with it. I can't remember what in the end the problem was, but my translations are now stored in UTF-8 files, and read into memory (a collection) with a specific routine. Assigning Unicode tooltips to the CCR Toolbar runs smoothly using the following code:
Code:
For Each oButton In oControl.Buttons
'Toolbar control, replace tooltip texts of button
sTranslationID = oForm.Name & "." & sControlName & "." & oButton.Key
If Not g_oTranslationCol.Item(sTranslationID) Is Nothing Then
oButton.ToolTipText = g_oTranslationCol.Item(sTranslationID).TranslatedText
End If
Next
Re: [VB6] - Multi-line standard tooltip.
Thanks a lot! And it can only display 127 characters, how to support display more content if need.
Re: [VB6] - Multi-line standard tooltip.
I took the liberty to enhance The original module so it supports unicode text, and remove the 255-characters limit.
I did so by allocating a pointer to store the unicode string, and save the pointer as the control's tooltiptext.
When drawing, retrieve the string from pointer, and draw using DrawTextW.
I didn't ask permission from the owner though. (Should I?)
If anyone is interested, I will post the enhanced module.

Yes of course. On the contrary, I'm glad that the module is being improved.

Re: [VB6] - Multi-line standard tooltip.
Usage:
On Form_Load:
To set unicode tooltiptext to control:
Code:
UniToolTip(ctl) = mytttStr
or, to also set alignment in multiline text:
Code:
SetUniToolTip ctl, mytttStr, Alignment
Where Alignment can be 0,1,2 (Left,Center,Right)
Add 4 for Right-To-Left text (4,5,6)
There is also an automate function to load an entire form's control's unicode tooltiptext, given the original codepage of your form.
This will work even if the destination computer has a different codepage!
Get tooltiptext:
Code:
myStr = UniToolTip(ctl)
On Form_Unload (important!):
Code:
UnhookTTT
FreeTTT Me
FreeTTT is to free the memory allocated for strings.
You can also use:
Code:
UniToolTip(ctl) = ""
to free the memory.
Every time you call HookTTT (e.g. calling in different forms), an internal counter is increased.
When you call UnhookTTT, the counter is decreased, and when reached 0 - the hook is removed.
To force hook removal - set parameter force to true.

Re: [VB6] - Multi-line standard tooltip.
An upgrade to the project!
New features:
* Works well in IDE - no crash!
* No need to hook/unhook - it is all done automatically
Old features - support Unicode, multi-line, no length limit
It is now moved to a class module
No need to make an instance of the class.
Usage:
cUniToolTips(ctl) = mytttStr
'Clear memory for current form:
Private Sub Form_Unload(Cancel As Integer)
cUniToolTips.UniToolTipUnloadForm Me
End Sub
