AVAppOpenDialog fails in Windows Acrobat 32-bit but okay in Acrobat 64-bit in latest Acrobat release

Report · Sep 26, 2023

I included a snippet of sample code [found here:

https://opensource.adobe.com/dc-acrobat-sdk-docs/library/plugin/Plugins_Documents.html ]

into my plug-in code. When executed, after the open dialog is displayed and user selects a file, Acrobat crashes. The same code compiled for Acrobat 64-bit runs without issues.

This test was performed after my plug-in (that runs similar code) crashed in a similar manner. The crash after AVAppOpenDialog started in the most recent release (2023.006.20320). The code did not crash in any of the previous versions of Acrobat.

I know I can replace the AVAppOpenDialog with a Windows file dialog - but would like to know why this is happening only in the latest release.

Any help or insight would be greatly appreciated.

ASPathName OpenPDFFile()

{

//Declare an AVOpenSaveDialogParamsRec object

AVOpenSaveDialogParamsRec dialogParams;

//Create local variables

AVFileFilterRec filterRec, * filterRecP;

AVFileDescRec descRec;

ASPathName* pathName = NULL;

ASFileSys fileSys = NULL;

ASBool bSelected = false;

char errorBuf[256];

//Set up the PDF file filter description

strcpy(descRec.extension, "pdf");

descRec.macFileType = 'PDF ';

descRec.macFileCreator = 'CARO';

//Set attributes that belong to the AVFileFilterRec object

memset(&filterRec, 0, sizeof(AVFileFilterRec));

filterRec.fileDescs = &descRec;

filterRec.numFileDescs = 1;

filterRecP = &filterRec;

//Set attributes that belong to the AVOpenSaveDialogParamsRec object

memset(&dialogParams, 0, sizeof(AVOpenSaveDialogParamsRec));

dialogParams.size = sizeof(AVOpenSaveDialogParamsRec);

dialogParams.fileFilters = &filterRecP;

dialogParams.numFileFilters = 1;

DURING

//Set the AVFileFilterRec object's filterDescription attribute

filterRec.filterDescription = ASTextNew();

ASTextSetEncoded(filterRec.filterDescription, "Adobe PDF Files",

ASScriptToHostEncoding(kASRomanScript));

//Set the AVOpenSaveDialogParamsRec object's windowTitle attribute

dialogParams.windowTitle = ASTextNew();

ASTextSetEncoded(dialogParams.windowTitle, "Select A PDF To Open",ASScriptToHostEncoding(kASRomanScript));

//Display the Open dialog box - pass the address of the ASFileSys object

bSelected = AVAppOpenDialog(&dialogParams, &fileSys, (ASPathName**)&pathName, NULL, NULL);

HANDLER

//Display an error message to the user

ASGetErrorString(ASGetExceptionErrorCode(), errorBuf, 256);

AVAlertNote(errorBuf);

END_HANDLER

//Destroy the ASText object then return

ASTextDestroy(filterRec.filterDescription);

ASTextDestroy(dialogParams.windowTitle);

return bSelected ? *pathName : NULL;

}

Even we also observed that AVAppOpenDialog is crashes in 32 bit, This code works fine in previous version.

Crashes is happening from most recent release (2023.006.20320).

Fix to this issue in coming new release would be greatly appreciated.
