Example of AEGP_GetNewText()?

[_logix812_]

Can anyone post up an example of AEGP_GetNewText.

I am basically here (everything executes properly I am just adding some snippets to frame the context):

AEGP_StreamValue val;
AEGP_StreamRefH text_streamH = NULL;
A_Time timeT = {0,1};

suites.StreamSuite2()->AEGP_GetNewLayerStream(
S_my_id,
layerH, AEGP_LayerStream_SOURCE_TEXT,
&text_streamH);

suites.LayerSuite5()->AEGP_GetLayerCurrentTime(layerH, AEGP_LTimeMode_LayerTime, &timeT);

suites.StreamSuite2()->AEGP_GetNewStreamValue(
S_my_id,
text_streamH,
AEGP_LTimeMode_LayerTime,
&timeT,
TRUE,
&val);

So that is where I sit. Now when I do this:
AEGP_MemHandle textMemory;
suites.TextDocumentSuite1()->AEGP_GetNewText(S_my_id, val.val.text_documentH, &textMemory);

I get the following Error from After Effects when I run the plugin:
After Effects error: internal verification failure, sorry! {Must clear unicodePH}
(5027 :: 0)

So clearly I am doing something wrong here.. Any Pointers?

Looking in AE_GeneralPlug.h on line: 1649 it says:
"handle of A_u_short, must be disposed with AEGP_FreeMemHandle"

So I figured, ok, I will make an A_u_short, and pass it into the argument as reference. Then throws an error on compile:
Invalid conversion from 'A_u_short to '_Up_OpaqueMem**'

Which makes sense since the signature of the method says it wants an AEGP_MemHandle. But I figured it was worth a shot.

Can anyone tell me how I go about clearing something?

I have tried delete and AEFX_CLR_STRUCT but no matter what i do I get an error:

Must clear unicodePH

[_logix812_]

Here is where I am at so far:

AEGP_StreamVal stream_valP;
AEGP_StreamType stream_type = AEGP_StreamType_TEXT_DOCUMENT;
AEGP_MemHandle unicodePH = NULL;
A_u_short *stringValue = NULL;

AEFX_CLR_STRUCT(stream_valP);

ERR(suites.StreamSuite2()->AEGP_GetLayerStreamValue(layerH,
AEGP_LayerStream_SOURCE_TEXT,
AEGP_LTimeMode_LayerTime,
&timeT,
TRUE,
&stream_valP,
&stream_type));


ERR(suites.MemorySuite1()->AEGP_NewMemHandle( S_my_id,
"Text Title Data",
sizeof(A_u_short),
AEGP_MemFlag_CLEAR,
&unicodePH));

ERR(suites.TextDocumentSuite1()->AEGP_GetNewText(S_my_id, stream_valP.text_documentH, &unicodePH));

ERR(suites.MemorySuite1()->AEGP_LockMemHandle(unicodePH, (void **)&stringValue));

ERR(suites.MemorySuite1()->AEGP_UnlockMemHandle(unicodePH));
ERR(suites.MemorySuite1()->AEGP_FreeMemHandle(unicodePH));

I know I am not doing anything with it... I am just trying NOT to get a Must clear unicodePH Error anymore and I will go from there...

[_logix812_]

After Effects error: internal verification failure, sorry! {Must clear unicodePH}

( 5027 :: 0 )

^ that is the full error
That windows pops up 3 times in After Effects (7)

if I comment out this line:
ERR(suites.TextDocumentSuite1()->AEGP_GetNewText(S_my_id, stream_valP.text_documentH, &unicodePH));

I don't get that error window

First, congratulations on trying so many things on your own; nice work!

Second, any time the function name contains 'new', AE will allocate the handle to hold the text for you.

Try this (works here).

AEGP_MemHandle my_cool_textH = NULL;

ERR(suites.TextDocumentSuite1()->AEGP_GetNewText(S_my_id, stream_valP.text_documentH, &my_cool_textH));

There's your unicode string.

I have the following code, and it fails all the time:

    AEGP_StreamVal2 stream_valP;

    AEFX_CLR_STRUCT(stream_valP);

    A_Time inPoint = {0,0}, layerDuration = {0,0};

    ERR( suites.LayerSuite7()->AEGP_GetLayerInPoint(layerH, AEGP_LTimeMode_CompTime, &inPoint) );

    ERR( suites.LayerSuite7()->AEGP_GetLayerDuration(layerH, AEGP_LTimeMode_CompTime, &layerDuration) );

    AEGP_CompH comp = NULL;

    ERR( suites.LayerSuite7()->AEGP_GetLayerParentComp(layerH, &comp) );

    A_FpLong fps = 0.0;

    ERR( suites.CompSuite8()->AEGP_GetCompFramerate(comp, &fps) );

    A_u_long interval = static_cast< A_u_long >(static_cast< A_FpLong >(layerDuration.scale) / fps);

    for (A_Time timeT = inPoint; stream_valP.text_documentH == NULL || *stream_valP.text_documentH == NULL || inPoint.value * layerDuration.scale == layerDuration.value * inPoint.scale; timeT.value += interval) {

        AEGP_StreamType stream_type = AEGP_StreamType_TEXT_DOCUMENT;

        AEGP_MemHandle unicodePH = NULL;

        A_u_short *stringValue = NULL;

        AEFX_CLR_STRUCT(stream_valP);

        ERR(suites.StreamSuite4()->AEGP_GetLayerStreamValue(layerH,

            AEGP_LayerStream_SOURCE_TEXT,

            AEGP_LTimeMode_CompTime,

            &timeT,

            TRUE,

            &stream_valP,

            &stream_type));

    };

    if (stream_valP.text_documentH != NULL && *stream_valP.text_documentH != NULL) {

        AEGP_MemHandle my_cool_textH = NULL;

        ERR(suites.TextDocumentSuite1()->AEGP_GetNewText(pluginId, stream_valP.text_documentH, &my_cool_textH));

        wchar_t *ch = NULL;

        ERR(suites.MemorySuite1()->AEGP_LockMemHandle(my_cool_textH, (void **)&ch));

        std::wstring tmp = ch;

        ERR(suites.MemorySuite1()->AEGP_UnlockMemHandle(my_cool_textH));

        ERR(suites.MemorySuite1()->AEGP_FreeMemHandle(my_cool_textH));

    }

Edit:

I get: Unhandled exception at 0x00000000060C6342 (U.dll) in AfterFX.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF, and that happens on the line:

ERR(suites.TextDocumentSuite1()->AEGP_GetNewText(pluginId, stream_valP.text_documentH, &my_cool_textH));

wchar_t* res16B;

....

ERR(suites.MemorySuite1()->AEGP_UnlockMemHandle(memH));
