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, etc, but the screen never redraws

Points of note:


If you break into the debugger at this point there is no user code running, it's all WPF
Killing DWM.exe brings the application back to life
If we take out the BitmapCached elements, it doesn't lock up
I made another simple sample application which used BitmapCache, and it didn't exhibit the problem.

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).

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: 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

dwm.exe: 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).

There are serious delays and the window is repainting slowly.

csrss.exe: make a windows 7 machine crash on BSOD

I'm trying to write a windows debug utility and I would need to automatically crash a Windows machine and make a Blue Screen Of Death appear.

I can obviously kill the csrss.exe process from the task manager, but the command TASKKILL /F /IM csrss.exe in a .bat file doesn't work.

Is there another way to make a Windows machine crash on bsod? Maybe some external library able to kill any process.

I would prefer to use a command line approach since I'm more familiar with it.

services.exe: How to read a REG Value into an Environment Variable

I am trying to read a REG Value into an Environment Variable in a BAT file. E.g.,

REG HKLMSYSTEMCurrentControlSetServicesEventlog /v ImagePath

I can get the entire output string of the REG command into an environment variable like this:

FOR /F 'usebackq delims==' %%a in (`REG QUERY 'HKLMSYSTEMCurrentControlSetServicesEventlog' /v ImagePath`) DO set ImagePath=%%a


However, this sets the environment variable to the entire line, i.e.,

eudora.exe: How to log all API calls in Windows the same way Wine does in Linux?

Im debugging a windows application in Linux using wine (Eudora), using WINEDEBUGGER=+relay to create a (rather massive) log of API calls. Now that I've spotted where the problem is, I want to run the same application in native windows (well, actually VirtualBox), so see how it behaves and compare the differences (if any).

I know there are several windows tools that can trace API calls, but i need one that can generate the same kind of log as wine does, so I can use the same workflow:
