[VB6] - Modify the standard ListBox.

http://s7.hostingkartinok.com/upload...0da6b5129b.png

Make a class with which you can modify the drawing standard list. He has event Draw, which is caused when the need render the next element of the list. To work, you need to install in the list of style Checked (flags), and assign this property ListBox clsTrickListBox.ListBox. You can also change the height of the elements and to cancel drawing.

Good luck!
Attachment 123639

Hi, I can´t dowload the zip attached.
Regards

Eduardo

You're right! I Just get a black screen.

I don't know reason. I've attached again.

hi,i added a button name like Refresh button (code in refresh button is clear list box and then add again 300 item to list box)
1-i added more than 300 items to list box and then clicked on refresh (this time list box fill slow more than previeus time)
and then clicks on refresh again and then slow more than 1.
and after click on refresh button after 5 times or more,program will be crashed.
how can fix this problem?

i want clear list box and then fill without crash problem.
any body here can fix tricklistbox?

Black_Storm, hi. Please attach the project that causes the error.

hi i attached here.
see lreloadnews_Click() and initdata() subrutin

initdata will be clear listbox tricked (list name is lstTest(0)) and then fill again
at first run,programm will be load json data and xml from urls and then fill lists and temp lists for search and then fill lstTest(0)
initdata() used for form load and then for refresh news.
click on refresh button and there is no problem for 1 time or less than 5 or 6 times but after it process will be slow ...
another problem is about when time i click on items in lstTest(0) and then click on lreloadnews.(slow process and then slower for click again and again)

i am looking for list view support right to left and like telegram list box ( my thread : http://www.vbforums.com/showthread.p...75#post5266475).

Black_Storm, you don't release resources (you can just scroll list and see task manager GDI objects):
https://s8.hostingkartinok.com/uploa...628cb54e3b.png

Code:

---

DeleteObject SelectObject(hdc, CreateMyFont("Tahoma", 8, 0, False))

---

You shouldn't make similar calls. You can create the fixed set of fonts in Form_Load:

Code:

---

hFont(0) = CreateMyFont("tahoma", 9, 0, False)
hFont(1) = CreateMyFont("tahoma", 8, 0, False)
hFont(2) = CreateMyFont("tahoma", 7, 0, False)

---

Next you can use that fonts:

Code:

---

...
oFnt = SelectObject(hdc, hFont(1)) ' save dc font
...
SelectObject hdc, hFont(0)
...
SelectObject hdc, hFont(2)
...
SelectObject hdc, oFnt ' To restore dc font
...

---

And you should delete the set of fonts at end:

can u fix problems and send to me again? ( without refresh problem after more than 10 times click?)

I've attached the example (note i didn't change all your code logic, only errors with listbox).

thanks for your help

-how can change scrollbar theme and define hover effect? ( my means of hover effect is solid color or gradiant color or png image for hover?)
-how can set background image?

Black_Storm, you need to implement custom scrollbar. Current list uses system scrollbar.

i am not pro for work with graphics but can u send a simple using this tricklistbox and with :

-changed scrollbar theme
-background image of list box changed
-hover item color changed(solid color or gradiant color or png background hover)
-alternative color for items
or how can show image(not icon) like as png for each item?(i used icon 150x35 pixel) but in draw event always show square size.

I don't have such example.
I think for all your requirements (#15 post) it's simple to create your own custom usercontrol.

You should process WM_CTLCOLORLISTBOX. An example in Russian:

hover item color changed(solid color or gradiant color or png background hover)

---

Use TrackMouseEvent you can register hovering and when you get WM_MOUSEHOVER you can process it. Solid color - FillRect, gradient - GradientFill, picture - BitBlt/AlphaBlend/GDI+.

Code:

---

alternative color for items

---

SetTextColor.

Use GDI/GDI+ function to draw an image.

I think for all your requirements (#15 post) it's simple to create your own custom usercontrol.


You need to implement custom scrollbar.

You should process WM_CTLCOLORLISTBOX. An example in Russian:

I'd say that this is something you will need to work out on your own. The Trick is under no obligation to write the code for you. If they don't want to release some source code for whatever reason, then that is their right. You can start a thread with the questions you want answered (though not here in the CodeBank), but otherwise, you'll have to consider this has reached an end.
