 MAC: create control or Window without NIB |
|
|
Just see a way to create button by code. Very interested in create Mac application purely by code and without anything from IB.
http://www.cocoadev.com/index.pl?NSButton
For Window and how an application load an window without an NIB, see this one,
http://objectmix.com/c/177994-how-create-windows-without-nib.html
Code :
int main(int argc, char *argv[])
{
NSWindow *mainwin;
MainView *mainview;
NSRect scr_frame;
unsigned int style_mask;
NSAutoreleasePool *pool =[[NSAutoreleasePool alloc] init];
[NSApplication sharedApplication];
scr_frame=[[NSScreen mainScreen] visibleFrame];
style_mask=NSClosableWindowMask|NSMiniaturizableWi ndowMask|
NSResizableWindowMask|NSTitledWindowMask;
#ifdef GNUSTEP
scr_frame=[NSWindow frameRectForScreenRect:scr_frame styleMask:style_mask];
#endif
scr_frame=[NSWindow contentRectForFrameRect:scr_frame
styleMask:style_mask];
mainwin=[[NSWindow alloc]
initWithContentRect:scr_frame
styleMask:style_mask
backing:NSBackingStoreBuffered
defer:NO];
[mainwin makeKeyAndOrderFront:nil];
[mainwin setTitle:@"Visible screen window"];
mainview=[[MainView alloc] initWithFrame:scr_frame];
[mainwin setContentView:mainview];
[mainwin setReleasedWhenClosed:YES];
[pool release];
[NSApp run];
return 0;
}

| Get print result from SQL statement |
|
|
Some of my colleague is lazy, and create the report in SQL and refuse to create an interface for user to execute the SQL. The SQL looks like below. The 'print' make the result in the SQL server management message window. So I'm thinking to make an interface but I do not want to change the SQL, so that is mean I need to get the result from the 'print'. The google told me it is possible to create it through register an call back fuction is CS, but I want an C++ interface. So I finally find ODBC can do it.
Code : Set @DueFromPBOC =(Select isnull(sum(isnull(ac.AccountBalance,0)),0) From View_Account_Log ac
Print 'Result = '+ Convert(varchar(50), @DueFromPBOC)
The process is just like below,
SQLAllocEnv
SQLAllocConnect
SQLConnect
SQLPrepare
SQLExecute
after that, using SQLGetDiagRec to find out the result from the SQL 'print'
Code :
i=1;
while ((rc2 = SQLGetDiagRec(SQL_HANDLE_STMT, hstmt, i, SqlState, &NativeError,
Msg, sizeof(Msg), &MsgLen)) != SQL_NO_DATA)
{
//DisplayError(SqlState,NativeError,Msg,MsgLen);
//printf("%s, %srn",SqlState, Msg);
printf("%srn",Msg);
i++;
// }
}
There are two points here,
1. The SQL sentence must have an zero (0x0) end, to let SQL server know the end of the sentense
2. Must use SQLExecute instead of SQLExecDirect, SQLExecDirect can not reture the entired message, and only reture first part if you have several select statement in one batch. |
