This routine formats two message strings--one containing messagebox text,

|
and the other containing a messagebox caption. The message box is then

|
|
displayed.
|
||
|

|
The message ids can be either a message in this dll's message table
|
||
|
|
resources or a win32 error code, in which case a description of
|
||
|
|
that error is retreived from the system.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
hinst - Supplies the handle of the module containing string resources to
|
||
|
|
be used.
|
||
|
|
|
||
|
|
hwndParent - Supplies the handle of window to be the parent of the message box.
|
||
|
|
|
||
|
|
TextMessageId - Supplies message-table identifier or win32 error code
|
||
|
|
for the messagebox text.
|
||
|
|
|
||
|
|
TitleMessageId - Supplies message-table identifier or win32 error code
|
||
|
|
for the messagebox caption.
|
||
|
|
|
||
|
|
Style - Supplies style flags for the message box.
|
||
|
|
|
||
|
|
... - Supplies arguments to be inserted in the message text.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
The return value is zero if there is not enough memory to create the message box, or
|
||
|
|
if a failure occurred while creating the message box.
|
||
|
|
|
||
|
|
If the function succeeds, the return value is one of the following menu-item values
|
||
|
|
returned by the dialog box:
|
||
|
|
|
||
|
|
IDABORT Abort button was selected.
|
||
|
|
IDCANCEL Cancel button was selected.
|
||
|
|
IDIGNORE Ignore button was selected.
|

|
IDNO No button was selected.

|
IDOK OK button was selected.

|
|
IDRETRY Retry button was selected.
|
||
|
|
IDYES Yes button was selected.
|
||
|
|
|
||
|
|
If a message box has a Cancel button, the function returns the IDCANCEL value if
|
||
|
|
either the ESC key is pressed or the Cancel button is selected. If the message box
|
||
|
|
has no Cancel button, pressing ESC has no effect.

|
|
The message id can be either a message in this dll's message table

|
that error is retreived from the system.
|

|
|
Arguments:
|
||
|
|
|

|
|
MessageId - supplies message-table identifier or win32 error code
|
||
|
|

|
||
|
|
|
||
|
|

|
||
|

Return Value:

|
Pointer to buffer containing formatted message. If the message was not found
|
||
|
|
or some error occurred retreiving it, this buffer will be empty.
