INTRODUCTION AND RELEVANT INFORMATION:

I have a complex painting to implement in my main window’s WM_PAINT handler.

I have submitted a picture bellow to illustrate it:
http://pbrd.co/18fNYYp[^]

Main window has static controls, instead of buttons, which have style SS_NOTIFY.
When user clicks on them, certain actions occur in program, which are irrelevant for now.

The following picture shows where static controls in the main window are:
http://pbrd.co/18fOkya[^]

Map on the orange panel is an EMF file ,top left and right logos are PNG files, and other pictures are bitmaps.

Visual Styles are enabled via #pragma directive. I also use GDI+ along with the GDI.

Project was created as empty project and I have coded everything from “scratch”.

In order to implement this task, I have decided to draw the entire picture in WM_PAINT, and to put transparent static controls over the images on the picture that correspond them.

In order to keep my code clean and simple, I have made functions that implement the above, so my WM_PAINT handler can be as small as possible.

Gradient brushes were made with the usage of GradientFill(...) API.

I work on Windows XP, using MS Visual Studio C++ 2008 Express Edition and pure Win32 API.

One note: since Express edition of VS doesn't have resource editor, resource file and resource header were created using ResEdit from here:
http://www.resedit.net/.[^]

UPDATE #1( updated on December 17th, 2013 ):

In order to make things easier for those trying to help, here is the single source file with minimal code that illustrates the problem: http://pastebin.com/BeAVHViC[^]

PROBLEM:

In order to avoid flickering, I have used double buffering, which I have learned from Paul Watt’s articles, Charles Petzold’s Programming Windows 5th edition and Forger’s WIN32 tutorial.

Theoretically speaking, everything is OK, and my code compiles without any errors.

I have pasted the code here:
http://pastebin.com/zSYT1i8L[^]

My English is not good enough to accurately describe the problems that I face ( all I can say is that edges of the main window and static control's redraw “slow” and they flicker ) so I have created a demo application that demonstrates them:
http://www.filedropper.com/geotermistgrafika[^]

MY EFFORTS TO SOLVE THE PROBLEM:

I have handled WM_ERASEBKGND ( returned (LRESULT)1 ), and I have excluded styles CS_VREDRAW and CS_HREDRAW from my window class-therefore flickering should not be caused because of this.

My window doesn’t have WS_CLIPCHILDREN style because part of the desktop picture is seen where static controls are.

In my WM_SIZE handler I have :
1. Repositioned static controls using SetWindowPos(...) API and reduced flickering by adding the SWP_NOCOPYBITS flag.

2. Invalidated the entire window with the InvalidateRect( hWnd, NULL, FALSE ), so this API does not send WM_ERASEBKGND when invalidating ( 3rd parameter is FALSE ), but even if I try with TRUE the effect is the same.

I have implemented double buffering for WM_PAINT handler like in the examples found in the above books/articles/tutorials ( by doing everything in the memory DC and do BitBlt(...) on screen DC in order to avoid flickering ).

I didn’t handle WM_SIZING, nor WM_WINDOWPOSCHANGING, or WM_MOVING message.

I have used the tool GDIView ( http://www.nirsoft.net/utils/gdi_handles.html[^] ) to track down GDI leaks.
Each time I resize/maximize my window, GDIView shows +4 in column for regions, which should mean that I leak regions but I can’t figure out how is this possible, since I do not use API’s that manipulate with regions, and have double checked everything.

In my opinion everything should be fine and maybe this is irrelevant, but I just thought to mention it, in case it is important.

If I add WS_EX_COMPOSITED style to the main window, the performance does not improve.

I have tried to find online example that would help me to solve my problem but all the tutorials are simple and do not cover this type of complex pictures.

IMPORTANT NOTE:

Before improving this question, I got two solutions suggested, one of them advising me to do as much as I can in WM_ERASEBKGND.

After leaving my WM_PAINT handler empty and calling onPaint function in WM_ERASEBKGND with the device context obtained with GetDC(..) API, the flickering disappeared, but during the resizing, redrawing of the window was “spiky” and the problem with the edges of the main window was not solved.
Still, this is much better improvement than the original code.

UPDATE ( December, 17th 2013 ):

After removing the call drawImages( hdc, MemDC, r ); from onPaint, the flickering of the edges occurs again.

It seems less, and the number of regions GDIView detects as leaked is reduced by one.

QUESTION:

How to get rid of the problems demonstrated in my demo application, provided above?

I hereby thank anyone who invests its time and efforts to try to help me.

Best regards.

Hi ALNS! Put all the code that you have written for your WM_PAINT function and put it into an overridden OnDraw function. The fact that you are using WM_PAINT to do all that is causing your flicker problems to begin with. WM_PAINT is best used to redraw a small part of the screen image that is active. Using the OnDraw function is faster, and better.

Just call all the routines that you have already written, modify your onPaint function a little. What happens is that you get the whole screen in memory before it is drawn, so that when you move or resize, overrides that you need handle, and need to reflect the OnDdraw called in the proper place in the main function, and in the case statements of your window messages.

Thank you so much for the advice!

That is a bit unclear for me, since as a beginner, I do not have a concept on how to override WM_PAINT ( and I struggle to find an example of it, since I work in pure WIN32 API ).

Can you please help me with some pseudo code, or some link that has an example?

Currently I am searching for this here at CodeProject articles, but I have no luck...

Hopefully this isn't much of a problem for you...

Thank you again for your advice!

Best regards :)

Without viewing your code, how can we help you?

Mr.Pallini,

The link to the code is attached in the section PROBLEM, subsection EDIT #1 ( December, 9th 2013 ) :and the demo project is attached just above, too.

Regards.

CPallini is absolutly right. Painting with WM_PAINT or the OnPaint method leads to flickering. Draw most things with the WM_ERASEBKGND message.

read some articles about "paint for beginners". Key is to avoid redrawing.

http://www.codeproject.com/search.aspx?q=paint+for+beginners&x=-1262&y=-146&sbo=kw[^]

I solve these problem via iterating: only draw one piece and if it works, i activate the next as long as it work...

Tip: dont work with controls, but check the mouse coordinates and handle it via posting messages to the windows.

Very interesting comment about Draw most things with the WM_ERASEBKGND message. I must give it a try sometime.
The_Inventor 11-Dec-13 0:11am    
@KarstenK : why don't you give credit where it is due. CPallini didn't make the comment, I did. If Always makes a function called OnDraw(CDC* pDC) and puts everything into 'memory' prior to 'Drawing' it, then there should be no flicker.
KarstenK 11-Dec-13 6:11am    
Problem on the edge is the typical use case for regions. Create a region only for the area you want to draw. Like here: http://www.codeproject.com/Articles/1944/Guide-to-WIN32-Regions

@The_Inventor: sorry!
AlwaysLearningNewStuff 17-Dec-13 12:42pm    
Thank you so much for your suggestions, I really appreciate it!

I have read most of the articles from that link before ( especially those from Paul Watt), so I could learn double buffering properly.

To establish "common ground" in further communication, let us divide the picture in the following sections:

1. Header
2. Middle part
3. Pictures of transparent static controls ( 4 blue ones and the ones on orange panel )
4. Footer ( or "status bar " )

From your last comment I understand that you have probably meant to first draw header in WM_ERASEBKGND, and then if it works, to add drawing of the middle part and so on, can you confirm if I have understood it right?

By the way, I have removed onPaint and left typical empty WM_PAINT handler.

I have recoded onPaint to use GetDC(..) and ReleaseDC(...) and flickering disappeared, but repainting is “slow” and the problem with the edges remained.

Thanks again for trying to help, can you suggest some improvements based on this new information I have delivered?

UPDATE ( December, 17th 2013 ) :

After removing the call drawImages( hdc, MemDC, r ); from onPaint, and trying to only draw background, the flickering of the edges occurs again.

It seems less, and the number of regions GDIView detects as leaked is reduced by one.

Best regards.

you really need to dig into "regions" and create a region of the window you want to draw. Regions are the key for your solution. ;-)

tips: + Try to make global instancess like the pens.
+ MoveToEx/LineTo are "slow" (consider using a bitmap)
Here is what I did with it. I left the drawImages function for you to rewrite.
You should be able to use CBitmap and CBitmap* without breaking your code.

Isn't CBitmap a part of MFC? (OP stated this a pure win32Api project with VS Express)
AlwaysLearningNewStuff 11-Dec-13 7:55am    
I was hoping that he tested his solution with the demo application I posted in my OP.

As for MFC, well, I am so desperate that I will "take whatever is offered" and try to create SDK solution on my own :)

P.S.

Are you just "visiting" or will you try to help me to deal with this "beast" ( in both cases I am glad to "see you" )?
enhzflep 11-Dec-13 8:11am    
I didn't try to compile the solution offered, so couldn't even begin to speculate.

I've seen it said that you can download the win32 DDK or SDK (I forget which) and use the MFC included in it, with VS express. Don't know if (a) it's still possible and (b) if it goes against licensing rules. Pretty sure I read about that trick here, at CP amongst other places. Something like "MFC VS Express site:codeproject.com" would possibly be a good google search.

Not sure how I would characterize my viewing of this thread. I did note that when I tried some sample code in WM_ERASEBKGND of a quick test-app of my own, that without a handler for WM_SIZE or WM_MOVE, that only part of the window was updated. (I didn't try to force an uodate - I only responded to the erase message) I didn't look into the issue further as yet. So, I'm not sure If I'm going to learn or help in this thread. Interested and wanting to help, but just not sure if I posses the skills to do so, or if I will only be able to learn from the suggestions made by other members.

Nice to 'see' you too. I always appreciate a question that clearly describes the issue being tackled and what attempts have been made to overcome it. Your questions always do both in a way that I have great respect for. Its ever so frustrating trying to come-up with a work-around/solution to a given problem, only to be bluntly told "No good" or "Already tried it" or words to that effect. Your questions are always the total opposite of that in my experience. :thumbs-up:
The_Inventor 11-Dec-13 22:00pm    
That is most likely true. I #included afxwin.h. CBitmap is in that file header. I still believe he needs to handle both the WM_SIZE and WM_MOVE messages as well. I used his previous posted code, that has the WM_SIZE handled, just the WM_MOVE to do.
AlwaysLearningNewStuff 17-Dec-13 12:58pm    
I have tried to copy and paste your code, but it failed to compile saying fatal error C1189: #error : Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD[d].

After going in Project Settings->Configuration Properties->Use of MFC,, and specifying the Using MFC in a Shared DLL I get other errors.

Notice that I use PURE WIN32 and not MFC, so if you could provide pure Win32 solution I would highly appreciate it.

If you can not do it, then you could lay out your concept so maybe I could implement your solution with investment of my own effort ( I do not mind at all! ).

Thank you.

Best regards.
