Performance issue when resizing Win32 containing WPF

I am in the process of migrating an existing legacy project. For now we want to use C++/CLI as a bridge between business logic (native C++) and interface (WPF). I followed this MSDN article on how to host WPF content in a Win32 window as a starting point. However, I cannot wrap my head around this problem: Whenever I resize the host window...


There are serious delays and the window is repainting slowly.
It causes the Desktop Window Manager (dwm.exe) to increase dramatically in memory usage (2 GB in a few seconds of resizing)


I stripped down the code to its bare minimum. A simple, red WPF page and a normal Win32 project with little changes:

namespace ManagedCode {
using namespace System;
using namespace System::Windows::Interop;

void Create(HWND parent) {
HwndSource^ container = gcnew HwndSource(NULL, WS_CHILD | WS_VISIBLE, NULL,
0, 0, 100, 100, 'WPFCONTENT', IntPtr(parent));
Managed::WpfPage^ page = gcnew Managed::WpfPage();
container->RootVisual = page;
}
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {
...
case WM_CREATE:
ManagedCode::Create(hWnd);
...
}


This has to be something really stupid.

dwm.exe: F12 not working in Delphi debugger on Windows 7/8

Pressing F12 while the program is running in the debugger should break the execution and open the debugger. This works correctly on Windows XP (tested with D2007 and XE2) but fails on Windows 7 and 8 (also tested with D2007 and XE2; tested on three computers).

Registry is set up properly (Windows 7):


[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionAeDebug]
'UserDebuggerHotKey'=dword:00000000
'Debugger'=''C:Windowssystem32vsjitdebugger.exe' -p %ld -e %ld'

dwm.exe: Lost Windows 7 transparency DWM not working properly

After installing new theme from Microsoft (http://windows.microsoft.com/hr-HR/windows/downloads/snowflakes-and-frost-theme) my Windows 7 lost all its transparency (Aero) effects and placed Windows Basic as the actual theme.
I've been googling for my problem for an hour now and I have not found any solutions.
All my attempts to fix this issue have failed.


I've tried running the standard wizard for for fixing transparency problems and I got a response:

dwm.exe: Completely locking down Windows 7 using Python 3.2?

This might be a more difficult question since I don't even know how to do it outside of Python...

I want to write a terminal program that completely locks up my PC until a password is entered. In the locked state no one should be able to do anything outside the terminal. In it, the user may rampage and write silly commands, but he should not be able to switch windows, click outside of it, open the task manager, open the menu with Ctrl + Alt Gr + Del and so on.

dwm.exe: BitmapCache causes WPF application to lock up

Here's the scenario:

1: Our WPF application starts

2: The WPF application loads various user controls, including some that use the new BitmapCache feature in WPF 4

3: Hit ctrl-alt-delete or win+l or load another application which requires UAC

4: Cancel that stuff

The WPF application is now unresponsive, however it's WPF itself which is the problem. All the application logic on all the background threads is fine, and you can interact with it by pressing alt+f4,

dwm.exe: Problem with explorer.exe and dwm.exe in Windows 7 [closed]

I'm using Window 7 Ultimate. I get a problem with two processes, namely explorer.exe and sometimes dwm.exe.

The two processes tend to use cpu between 20-30%.

And it only occurs when i play some game on my PC. My PC works perfect until I play some game.

And another important observation:
They consume no cpu as such but only consumes when I try to refresh my desktop. I mean when I right-click on desktop. It takes seconds for refresh.

I have no virus problems.

dwm.exe: Dwm.exe memory leak when resizing simple WinForm application

I created very simple Winform application in VS2010 (just a standard template File->New->Project->C# Windows Forms Application).

After several form resizes the system memory consumption can increase by 1Gb or more! And this memory is not returned to the system after application closing. Selecting Classic theme or killing dwm.exe helps to get memory back.

Here is the simple video I recorded to show the problem: http://youtu.be/ZJMCayflrHI

Friends,

Need to screenshot of the all desktop WITHOUT MY FORM and load in TImage.
Success in Windows XP, 7 - with just ALPHABLEND = TRUE + SCREENSHOT PROCEDURE.

But same code does not work in Windows 8 - capture all screen INCLUDING THE FORM.

I know the problem is related to AERO - DWM.EXE - success using pssuspend.exe (sysinternals) - suspending winlogon.exe and killing dwm.exe

Someone could tell me how to capture all desktop without my form also in Windows 8?

dwm.exe: VB6 Drag and Drop Performance in Windows 8

I have a rather large VB6 application that features dragging and dropping controls between sub forms in an MDI application. The problem is the performance is really bad during the drag operation. You can see the element redrawing (slowly) as you drag it.

I first encountered this issue in Windows 7 and after some research concluded that it was a compatibility issue with the Aero interface. I was able to work around it by switching off the Aero effects. Now I am using Windows 8 the problem

reader: File reader encapsulation in a table reader

I have a file reader object that i need to read a file with tables in it. I want to create an object called Table to hold the row and column data from the read file. The trouble is, to read the whole page, i need to have a list of tables (there are more than one in the file). WHat is the best structure of my ides so that i am not exposing the data reader too much and passing it around too much?

My current line of thinking is this:

explorer.exe: Is there a way to control explorer.exe?

I am creating a desktop helper, and I was wondering whether there was a way to 'see' what explorer.exe does and respond to that. For example, if you could monitor whenever a user opened a specific folder. I would prefer a way in python as that is the main language of my project, but if there's a way in another language, then I'd probably be able to incorporate it.

(FWIW, I've posted this question to my blog as well: http://blog.wolffmyren.com/2011/07/11/ie-protected-mode-ssl/)

Does anyone know how to work around Internet Explorer Protected Mode limitations without requiring the end-user to add our site to the Trusted Sites list?

The problem is that if we enable SSL logins for our site, they can only access SSL pages. IE prevents our non-SSL served pages from accessing the cookie created during the SSL session, so we can either serve everythi
