I'm not sure why you wouldnt be able to call it. Where are you calling it now?

Sorry, I never heard about public functions. 
BTW what about a good C++ tutorial?

Definetely we can call it.. Don't know what problem you are facing? Could you elaborate please?
|
|
|
|

If you are saying that you have a class and inside that you have a public member function, then
you need to create an object of the class at the place where you want to call it. And then using that object you can call the function. You need to include the .h file in which you have created your class.
Well this is like targeting in dark..
If you can put the problem in detail. You may get right solution.

Im having a problem when I SetWindowRgn I lose the visual appearance of XP and Vista, as seen in Figure 1[^]. Any ideas of what I'm doing wrong?
Here is the code i'm using DialogTest.rar
Thanks

Yes, that's what SetWindowRgn does. How can Windows know how to attach a title bar to your region?
Applications that do this draw their own title bar and respond to WM_NCHITTEST to tell Windows which part of the UI has been hit. You can draw standard Windows controls with DrawThemeBackground/DrawThemeIcon/DrawThemeText etc, if theming is enabled, or DrawCaption/DrawFrameControl if not.

No, I understand that. I’m setting the region when the user presses the button, then unsetting the region when it's pressed again. The problem is that when I put back WS_CAPTION the window was being redrawn without visual styles. I just figured out that I was clearing the region after setting WS_CAPTION back to my window. I switched the order and every thing worked perfectly....
Thanks for your response.

Hi All
How can i remove duplicate values from listbox.Plz help me
|
|
|
|

How did your list box end up with duplicate values at first? The right way would be to not add duplicate values.

Thx's for responce
I am adding values at the run time in the list box.And i want if all ready data(same name of data) present then no new data add in the exiting list box.If different type of data(different name of data)came then add in this listbox.
Right now data add in proper way but i need to remove duplicate data.
Plz help me

I'm telling you not to add duplicate data at first place so that you won't have to worry about it at all. What is your difficulty in adding only non-duplicate values? How are you approaching it?

Well, it is not a difficult task: sort the data and then remove the duplicate entries comparing each item with the following (or prevoius) one.

can you give me some code example ..
Plz help me
|

You need to a loop and on the loop use of FindString.
|
|
|
|
|
Before calling AddString(), give a call to FindString(). If it returns -1, proceed with calling FindString().

I thought adding non-duplicate data would be the best way.

I wonder if you got downvoted for your answer because you didn't provide the full source code? Your answer is perfectly fine. Lot's of idiots around here.

Thank you.
Voting people sometimes has no adequate technical skills to do it, anyway that's part of the game.

for me, the best reason for why he's been downvoted is because patching a design issue with code is always a bad solution...
if the list mustn't have duplicates, then it just not have to accept them at first.

Actually Carlo suggested that because the OP himself was insisting on that. Even after I suggested him something that is more logical, he went around and asked again "how to do what I azked. pleaze show the sourze codez".

Generally speaking, maybe it is not a design issue (though, on common sense grounds, his code has such issue). Maybe you can't simply avoid duplicate items in the list (i.e. very fast insertion on data acquisition, list already buildt by code out of your control). I simply gave some hints to deal with the actual problem. Anyway I don't bother about downvoting: as I already said, it's part of the game.
