XTYP_ERROR
XTYP_ERROR
A dynamic data exchange (DDE) callback function receives the XTYP_ERROR
transaction when a critical error occurs.
Parameters
uFmt
Not used.
hconv
Identifies the conversation associated with the error. This parameter is NULL
if the error is not associated with a conversation.
hsz1
Not used.
hsz2
Not used.
hdata
Not used.
dwData1
Specifies the error code in the low-order word. Currently, only the following
error code is supported:
Error Code
| Description
| DMLERR_LOW_MEMORY
| Memory is low; advise, poke, or execute data may be lost, or the system may
fail.
|
dwData2
Not used.
Remarks
An application cannot block this transaction type; the CBR_BLOCK return code
is ignored. The DDEML attempts to free memory by removing noncritical resources.
An application that has blocked conversations should unblock them.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
