WIMGAPI UDF

[Homes32]

A UDF for manipulating Windows Image Files (.wim) without ImageX.exe

This UDF allows you to use the Windows Imaging API directly (wimgapi.dll) so you don't have to use a command line program such as ImageX. Benefits are wimgapi.dll is shipped with windows 7 so users don't have to download the 1gb+ AIK to manage wim files. The UDF also allows you to utilize callback functions so you can show detailed progress info to your users.

wimfltr.sys/wimmount.sys required for mount/unmount only.

working with both 32 and 64 bit builds.

its pretty well documented but you should still read the MS Imaging API documentation and be familiar how wimgapi.dll works to get the most out of this UDF.

functions marked with an (*) are only available with newer versions of wimgapi.dll

Functions Included:

_WIM_ApplyImage

_WIM_CaptureImage

_WIM_CloseHandle

_WIM_CreateFile

_WIM_DeleteImage

_WIM_DeleteImageMounts *

_WIM_ExportImage

_WIM_ExtractImagePath *

_WIM_GetImageAttributes

_WIM_GetImageCount

_WIM_GetImageInformation

_WIM_LoadImage

_WIM_MountImage

_WIM_RegisterLogFile *

_WIM_RegisterMessageCallback

_WIM_RemountImage *

_WIM_SetBootImage

_WIM_SetImageInformation

_WIM_SetReferenceFile

_WIM_SetTemporaryPath

_WIM_Shutdown

_WIM_Startup

_WIM_UnMountImage

_WIM_UnRegisterLogFile *

_WIM_UnregisterMessageCallback

have fun!

I assume this is Vista and later as I cannot seem to find those DLLs on XP or 2k3?

correct. for xp you will still need to download the AIK from Microsoft.

[JohnOne]

The primary purpose of Imaging APIs (Wimgapi.dll) is to programmatically capture, modify, and apply images for deployment in a manufacturing or corporate IT environment. Wimgapi.dll is now included by default in Windows 7. ImageX is an implementation of the Imaging APIs.

This is incredibly cool. I've been using GimageX for a while, and it works great. But this will help me to automate my imaging even more with my own custom scripts. Thank you very much for this UDF.

Glad you find it useful. its always nice to be able to give something back to a community that has been so helpful.

I've run into an issue with getting info from a wim image. Autoit will crash and the windows event log will always show

Exception code: 0xc0000005

which is a Access Violation error.

tracing the _WIM_GetImageInformation func it always crashes at this line

Func _WIM_GetImageInformation($hImage)

    Local $aReturn[2] ; array to hold the return data
    Local $ppvImageInfo = DllStructCreate("ptr") ; Buffer for XML Data
    Local $pcbImageInfo = DllStructCreate("int") ; Size of buffer in bytes

    Local $aResult = DllCall($ghwimgapi, "bool", "WIMGetImageInformation", _
            "handle", $hImage, _
            "ptr", DllStructGetPtr($ppvImageInfo), _
            "ptr", DllStructGetPtr($pcbImageInfo))
    If @error Then Return SetError(@error, @extended, 0)

    ; create a struct so we have access to the buffer where the XML data is stored
    Local $xml = DllStructCreate("wchar [" & DllStructGetData($pcbImageInfo, 1) & "]", DllStructGetData($ppvImageInfo, 1))
    $aReturn[0] = $aResult[0]
        $aReturn[1] = DllStructGetData($xml, 1) ; <-- ***CRASH OCCURES HERE***
    Return SetError(@error, _WinAPI_GetLastError(), $aReturn)
EndFunc   ;==>_WIM_GetImageInformation

according to the return codes the structs get created correctly and the size of $xml is always correct, yet quite regularly reading data from $xml fails miserably.

this doesn't happen every time the command is run but you can always reproduce by running the script several times in a row. the frequency seems random.

can anyone give me some insite as to what may be going wrong here?

some code to get everything up and running for anyone wanting to take a crack at this.

make sure to download the UDF from the above link.

thanks.

Homes32

Steps to Reproduce

If required change the path to the WIM file. In my tests the crashes were not specific to any particular WIM file.

Run the following code several times in a row using F5 from SCITE or compile the code and use a cmd/bat to run several times in a row.

It doesn't matter if you compile or use x68 vs x64, autoit will always have a hard crash at a seemingly random interval.

Test code:

Thanks a lot for this UDF.

can anyone give me some insite as to what may be going wrong here?

I second this question, could anyone help here?

hmm, it seems works that way

    Local $ppvImageInfo = DllStructCreate("ptr") ; Buffer for XML Data
    Local $pcbImageInfo = DllStructCreate("int") ; Size of buffer in bytes

    Local $aResult = DllCall($ghwimgapi, "bool", "WIMGetImageInformation", _
            "handle", $hImage, _

I have a theory and this might be a stretch becuase I don't know much about Dll calls and this image stuff but MSDN says to free it with LocalFree. So it's worth trying:

Func _WIM_GetImageInformation($hImage)
    Local $aReturn[2] ; array to hold the return data
    Local $ppvImageInfo = DllStructCreate("ptr") ; Buffer for XML Data
    Local $pcbImageInfo = DllStructCreate("int") ; Size of buffer in bytes

    Local $aResult = DllCall($ghwimgapi, "bool", "WIMGetImageInformation", _
            "handle", $hImage, _
            "ptr", DllStructGetPtr($ppvImageInfo), _
            "ptr", DllStructGetPtr($pcbImageInfo))
    If @error Then Return SetError(@error, @extended, 0)

    ; create a struct so we have access to the buffer where the XML data is stored
    Local $xml = DllStructCreate("wchar [" & DllStructGetData($pcbImageInfo, 1) & "]", DllStructGetData($ppvImageInfo, 1))
    $aReturn[0] = $aResult[0]
    $aReturn[1] = DllStructGetData($xml, 1) ; <-- ***CRASH OCCURES HERE***
    local_free($xml)

Homes32,

Great UDF! I'm having trouble with the callback routine to get an accurate progress percentage. When I try and run your sample script I get a variable used before declared error for $Percent. I was hoping maybe you could shed some light on it. Thanks.

Hi LaCastiglione,

thanks for replying.

I tried something like this already.

the Crash actually occurs During DllStructGetData($xml, 1)

so local_free($xml) will never be called.

Homes32,

Great UDF! I'm having trouble with the callback routine to get an accurate progress percentage. When I try and run your sample script I get a variable used before declared error for $Percent. I was hoping maybe you could shed some light on it. Thanks.

oops. my bad. just add $Percent as Global at the top.

I also updated the sample code to fix this.

thanks.

Hi!

I try to catch $WIM_MSG_PROGRESS from _WIM_ApplyImage. But I can't. Can you provide example func Apply($sWimFile, $iImageIndex, $Path) with working progress bar?

Thank you!

Thank you!

sorry. but currently the limitations of Autoit's callback implementation prevent this from working correctly. I'm sure it also doesn't help that the apply functions of wimgapi.dll are multi-threaded.

as far as I know nobody has every gotten the progress to work with /apply

forgot to upload v3 with fixed _WIM_GetImageInformation

thanks JFX for helping figure this out!

Do you have an example of the _WIM_ApplyImage() function. The code documentation seems to be a copy of the capture function.
