BUG: Write Incorrectly Fills Out the OLETARGETDEVICE Structure (94609)
The information in this article applies to:
This article was previously published under Q94609 SYMPTOMS
In an OLE server application's SetTargetDevice() method, the Device Name
string located at the otdDeviceNameOffset position of the otdData buffer
contained in the OLETARGETDEVICE structure is invalid.
CAUSE
Windows Write does not properly NULL-terminate the Device Name string.
RESOLUTION
The OLETARGETDEVICE structure contains information about a target
device. It is declared in OLE.H as:
typedef struct _OLETARGETDEVICE {
UINT otdDeviceNameOffset;
UINT otdDriverNameOffset;
UINT otdPortNameOffset;
UINT otdExtDevmodeOffset;
UINT otdExtDevmodeSize;
UINT otdEnvironmentOffset;
UINT otdEnvironmentSize;
BYTE otdData[1];
}
The otdData byte array contains a DEVMODE structure, which begins at
offset otdExtDevmodeOffset. The Device Name string can be extracted from
the dmDeviceName member of that DEVMODE structure.
STATUS
Microsoft has confirmed this to be a problem in Windows Write shipped
with Microsoft Windows version 3.1. We are researching this problem and
will post new information here as it becomes available.
