My Plugin 4.2:-

Added (Optional) Additional Thread Columns [Previous + New].
New (Optional) Thread Columns:-

1) Is IO Pending
2) Context Switches Value [Only For XP, Use Cycles Columns For Other OS]

I am still facing the problem over the selection of plugin from tool top data...Any other suggestions????

Hello,

I am Robert Bell.

I don't know what actually do you want ?

You can use the plugin by extracting dll file from previous post into plugins folder in processhacker.exe directory.

==>

Small plugin for Saving Selected Memory Items in separate bin files & selecting entries based on type for handles & network tab.

Thanks for the sharing error details.

Does This Work ?

I'll test it a bit.

My Plugin A2:-

"My Plugin A2" is same as "My Plugin A" but with following additions/changes:-

1) Also Contains "Select Type" option for Services Tab, Modules Tab, Threads Tabs.

1a) This uses different methods for generating menu(s) ( TreeListView Data (Columns & rows) to Right Click Menu )


2) "Process Type ( Colour Info )" Column For Processes Tab which shows highlighting colour meaning/information for each process (Experimental)

Screenshots in next post.

Please, give your Plugin a proper name, file version info (with Semantic Versioning: http://semver.org/) and a good filestamp (currently the plugin is from 2012!) and provide a public PDB (http://msdn.microsoft.com/en-us/library/ms241613.aspx) if you don't to share internal details.


Last version still causes hangs in ProcessHacker:

I tried to hang ph using my plugin for your specific rc file which shows similar errors but it didn't worked.

When i use my plugin, ph never hangs.


1) Can you please share "samdb.xml" which you use, when ph hangs ?

2) Can you please tell, after doing what ph hangs ( steps to reproduce ) ?


First let me resolve all your hangs, crashes & then i'll give the plugin a proper name & current timestamp.


I can share (public) PDB, no problem.


internal details => wait for some time, i'll share the source code for saving i/o & page priority.


3) Does the default exe provided on sf.net or googlecode when used with my plugin also hangs ?

The callstack shows its hanging in your PluginUnloadCallback

Thanks dmex.

I'll either remove PluginUnloadCallback function or fix it.

And re-upload the plugin.

Isn't this function called when you are exiting/closing ph ?

How does magicandre1981 say that my plugin hangs ph when it is running ?

The function contains code for saving data to file.

Ph Hangs When exiting or changing priority ?

sam wrote:

Yes, It should only be called when PH is exiting (e.g. Do not invoke the callback yourself ).

Not entirely sure but thats what the screenshot shows: PhUnloadPlugins > PhInvokeCallback > Sameer > Crash/Hang

Need more info from MagicAndre...

Hi dmex,

Thanks for replying.

Does the default exe also hang/crash ( when my plugin is used present on first page of this post for saving io page prio.. ) ?

Or this is only an issue for magicandre1981 ?

-----------------------------------------------------

Hi MagicAndre1981,

Forget "M P T 1.rar".


Use "Savepriority.rar" file build for your specific rc file.

PDB's are included.


Report on this file.

I start ProcHacker at startup and run it all the time. And sometimes I switched to PH and saw that it was hanging. So I kicked up ProcExp, created a dump and looked at it with Windbg.


I'll test the new version and see if I have the issue again. Btw, can you store the database XML in the same folder as the exe (to be fully portable)?

can you store the database XML in the same folder as the exe (to be fully portable)?

==> Yes.


But First test & report whether it works or not.

If it has no issues then i'll add portable xml function also or for the next test version.

ok, I've tested the last testing version and it fixed my issue. I no longer get freezes.

Thanks MagicAndre1981.




Portable Database File Option:-

To use this:-

Either use 'A' or 'B' :-

A) Create a blank file named "ProcessHacker.exe.samdb.xml" in the same directory as ProcessHacker.exe.

[ From Readme.txt File Provided in "Processhacker 2.xx.zip" file ]

You can do this using Windows Explorer:

1. Make sure "Hide extensions for known file types" is unticked in
Tools > Folder options > View.
2. Right-click in the folder and choose New > Text Document.
3. Rename the file to ProcessHacker.exe.samdb.xml (delete the ".txt"
extension).


B) Rename existing "samdb.xml" file to "ProcessHacker.exe.samdb.xml" & put/copy it in the same directory as ProcessHacker.exe.
