  • Getting Postfix to process the mail queue on Mac OS X

    - by paperclip
    I'm in the process of getting Sendmail/Postfix setup so that I can send and test my PHP scripts when using the mail() function. I've got to the point that when I run the mail() function in PHP, the script executes without any errors and the mail is sent to my mailq but it then does not get processed and simply times-out with a message of: Operation timed out. An excerpt from Terminal: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 137AA96B6C2 897 Tue Mar 16 22:27:05 [email protected] (connect to alt4.gmail-smtp-in.l.google.com[74.125.93.27]: Operation timed out) [email protected] Any ideas as to how I can fix this timeout issue? Thanks, -P.

  • Capture bitmap of window in isolation (Windows OS)?

    - by Jake Petroules
    I know there's a way to capture a bitmap of a window in Windows without anything that may be obscuring it (e.g. you have a window with a dialog in front, but the dialog is not captured as it would be if you did a simple pixel grab), but I can't remember how to do so. Also I believe this is only possible in Windows Vista and above, with the introduction of the compositing window manager?

  • Environment Variable to determine the OS type (Windows XP, Windows 7)

    - by Santhosh
    I want to differrntiate between Windows XP and Windows 7 in a XML file. Thought i will use an environment variable for it inside the XML. However I could not find any system environment variable defined in windows that gives this information. I see the %OSTYPE% variable but it is only available in Windows 7. It is not defined in XP. Is there anyway i could do this? Note that i would like a solution which purely depends on system environment variables. I do not want to create new variables based on executing some command, because i want to use this variable in a XML file.

  • audio error in vmware running mac os x

    - by PenguinSource
    simple synchronous loading of an audio file (.mp3) in a cocos2d app makes my vmware disconnect the sound. the error is display bottom right, saying 'error in creating sound stream; sound is disconnected' i read that it might be cause of my vmware's version (mine is 8) but I'm looking for a fix, not to downgrade to another version. before i get that error, the sound on the system works just fine (youtube, etc) the exact code im calling is.. [CDSoundEngine setMixerSampleRate: CD_SAMPLE_RATE_MID]; [[CDAudioManager sharedManager] setResignBehavior: kAMRBStopPlay autoHandle:Yes]; soundEngine = [SimpleAudioEngine sharedEngine]; [soundEngine preloadBackgroundMusic:@"somemp3.mp3"]; [soundEngine playBackgroundMusic:@"somemp3.mp3"]; maybe the bit rate is too high .. ? thanks

  • Outputing UTF-8 string on Mac OS's Terminal

    - by SuperBloup
    I got a programm in haskell outputting utf-8 using the package utf8-string and using only the output functions of this package. I set the encoding of each file I write to this way : hSetEncoding myFile utf8 {- myFile may be stdout -} but when I try to output : alpha = [fromEnum 0x03B1] {- a -} instead of the nice alpha letter I got on Linux (or in a file on windows), I got the following : α The weird thing is even if I try to write the output on a file, I can't read it back with mvim as an utf-8 file. Is there any way to get the correct behaviour

  • Building 16 bit os - character array not working

    - by brainbarshan
    Hi. I am building a 16 bit operating system. But character array does not seem to work. Here is my example kernel code: asm(".code16gcc\n"); void putchar(char); int main() { char *str = "hello"; putchar('A'); if(str[0]== 'h') putchar('h'); return 0; } void putchar(char val) { asm("movb %0, %%al\n" "movb $0x0E, %%ah\n" "int $0x10\n" : :"m"(val) ) ; } It prints: A that means putchar function is working properly but if(str[0]== 'h') putchar('h'); is not working. I am compiling it by: gcc -fno-toplevel-reorder -nostdinc -fno-builtin -I./include -c -o ./bin/kernel.o ./source/kernel.c ld -Ttext=0x9000 -o ./bin/kernel.bin ./bin/kernel.o -e 0x0 What should I do?

  • Can't delete a file created by mkstemp() on Mac OS X

    - by splicer
    Apparently, NSFileManager is unable to delete files created by mkstemp(). Here's some test code to demonstrate this: char pathCString[] = "/tmp/temp.XXXXXX"; int fileDescriptor = mkstemp(pathCString); if (fileDescriptor == -1) { NSLog(@"mkstemp failed"); } else { close(fileDescriptor); NSURL *url = [NSURL URLWithString:[NSString stringWithCString:pathCString encoding:NSASCIIStringEncoding]]; NSLog(@"URL: %@", url); NSError *error; if (![[NSFileManager defaultManager] removeItemAtURL:url error:&error]) { NSLog(@"could not delete file: %@", error); } } Here's what I see in the log when I run the above code: URL: /tmp/temp.A7DsLW could not delete file: Error Domain=NSCocoaErrorDomain Code=4 UserInfo=0x1001108a0 "The file “temp.A7DsLW” doesn’t exist." I'm running this on Snow Leopard. Any ideas on why the problem is occurring and/or how to work around it? Thanks!
