Well, my second idea does not work. Instead of publishing a SpawnDialog
event, I have a CA that displays a message box. However, the Message box
does not show up. Here are my functions to display a message (see below).
I'm certain that GenMessageBox gets called, because I put up a message box
(via MessageBox user32 function) that displayed "MYMSGTEXT", and the text
was correct. Am I missing something?
extern "C" UINT __stdcall GenMessageBox(MSIHANDLE hInstall)
{
CString strMsg;
DWORD dw = 1024;
UINT uiRet = MsiGetProperty(hInstall,"MYMSGTEXT",strMsg.GetBuffer(1024),&dw);
strMsg.ReleaseBuffer(); // reclaim the buffer after the GetBuffer() call.
if( ERROR_SUCCESS!=MsiMessageBox(hInstall,strMsg,MB_ICONINFORMATION) ) {
MessageBox(GetActiveWindow(),"MsiMessageBox failed.","Test",0);
}
return ERROR_SUCCESS;
}
UINT MsiMessageBox(MSIHANDLE hInstall,LPCSTR pszMsg,DWORD dwOptions)
{
if( NULL==hInstall || NULL==pszMsg ) return -1;
PMSIHANDLE hRec = MsiCreateRecord(2);
MsiRecordSetString(hRec,0,pszMsg);
UINT uiRet = MsiProcessMessage(hInstall,INSTALLMESSAGE(INSTALLMESSAGE_USER
| dwOptions),hRec);
return uiRet;
}

Can you clarify this? Here are all of the entries in my ControlEvent
table that pertain to the dialog that I am speaking about. I want the next
button to warn the user (via InfoDlg) when they are using "Local" mode. Are
you saying that If inside my InfoDlg, I publish a ControlEvent for the "OK"
button to set a property, and then condition my "NewDialog" event from the
SelectServerDlg on the property that the InfoDlg would change? I'm sorry if
I'm being obtuse. Another thing I could do is just add a CA that calls
MsiProcessMessage with MB_ICONINFORMATION to show the message as well. This
would achieve the same goal, correct?
