PrefOutputToMemory

 Top  Previous  Next

The PrefOutputToMemory specifies whether to create the file output in file or in memory.

 

 

 

 

Syntax

 

 

[VC++]

BOOL GetPrefOutputToMemory();

void SetPrefOutputToMemory(BOOL bNewValue);

 

[C#]

public abstract new bool PrefOutputToMemory [  get,  set ]

 

[VB]

Property PrefOutputToMemory As Boolean

 

 

 

 

 

 

Remarks

 

 

Setting this property to True will generate the output document in memory. No file will be created. The output data can be obtained by calling the function GetMemoryBuffer. It'll return the binary data as variant.

 

 

 

 

 

Default Value

 

 

False

 

 

 

 

Example Code

 

 

[VC++]

VARIANT varStream;

void *ptr, *ptrDest;

int Size;

FILE *fp;

       

// Initialize variant.

VariantInit(&varStream);

 

m_Engine.SetPrefOutputToMemory(true);

m_Engine.SetPrefOpenAfterCreate(false);

m_Engine.SetPrefShowSetupDialog(false);

m_Engine.BeginDoc();

m_Engine.TextOutXY(2, 2, "Gnostice eDocEngine ActiveX");

m_Engine.EndDoc();

       

// Obtain the generated document stream.

varStream = m_Engine.GetMemoryBuffer();

 

SafeArrayAccessData(varStream.parray , &ptr);

Size = varStream.parray->rgsabound[0].cElements;

ptrDest = new unsigned char[Size+1];

memcpy(ptrDest, ptr, Size);

SafeArrayUnaccessData(varStream.parray);

 

// write binary data from memory to a file.

fp = fopen("Output.pdf", "wb");

if (fp != NULL)

{

       fseek(fp, 0, SEEK_SET);

       fwrite(ptrDest, Size, 1, fp);

       fclose(fp);

}

 

delete ptrDest;
