Syntax

public void ReadDwgFile(
        string fileName,
        FileOpenMode mode,
        bool allowCPConversion,
        string password,
        bool bPartialLoad
)

Public Sub ReadDwgFile ( 
        fileName As String,
        mode As FileOpenMode,
        allowCPConversion As Boolean,
        password As String,
        bPartialLoad As Boolean
)

public:
void ReadDwgFile(
        String^ fileName, 
        FileOpenMode mode, 
        bool allowCPConversion, 
        String^ password, 
        bool bPartialLoad
)

member ReadDwgFile : 
        fileName : string * 
        mode : FileOpenMode * 
        allowCPConversion : bool * 
        password : string * 
        bPartialLoad : bool -> unit

Parameters

fileName String: [in] Path to the file to read.
mode FileOpenMode: [in] Open mode.
allowCPConversion Boolean: [in] Flag that specifies whether codepage conversion should occur silently.
password String: [in] Password for a file.
bPartialLoad Boolean: [in] Flag that specifies whether to perform partial loading of a file.

Remarks

Pieces of the drawing are read in only as needed. So, the drawing file is left open until the database object is deleted. The method attempts to open files with read access. The mode argument describes how other applications can access the file when the same file has already been opened. The allowCPConversion argument specifies whether to automatically perform a default conversion from the drawing codepage to the system codepage if corresponding files for conversion are not available (which might cause loss of data). If allowCPConversion is false, you are asked if conversion should be performed, otherwise conversion is performed silently. If password is NULL, the user is prompted for a password if required. This method should be used only with a newly created database created via its constructor's buildDefaultDrawing argument set to false. In all other cases memory leaks and fatal errors can occur. The bPartialLoad flag is optimal for use when you load large drawings and plan to work only with a small part of a drawing. This option can help save resources and time dedicated to vectorizing the file content compared to a normal loading model where all objects are loaded. Over time, some objects may be loaded and vectorized as needed which can cause slight freezes while working with a drawing.
