我试图在CentOS 6.2中将MySQL从5.1升级到5.5.以下是我做的过程:

1. rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
2. yum install libmysqlclient15 --enablerepo=webtatic
3. yum remove mysql mysql-*
4. yum install mysql55 mysql55-server --enablerepo=webtatic

当我尝试第4步时,我得到以下输出:

[root@d2005 /]# yum install mysql55 mysql55-server --enablerepo=webtatic

我必须从我的Java程序中打开一个.exe文件.所以我尝试了第一个代码.

Process process = runtime.exec("c:\\program files\\test\\test.exe");

但是我收到了一些错误.然后我发现exe必须从c:// program files/test /那个位置启动,然后它会打开而没有错误.所以我决定编写一个.bat文件并执行,以便它将cd到该位置并执行.exe文件.

以下是我的代码:

BufferedWriter fileOut;

String itsFileLocation = "c:\\program files\\test\\"
    System.out.println(itsFileLocation);
    try {
     fileOut = new BufferedWriter(new FileWriter("C:\\test.bat"));
     fileOut.write("cd\\"+"\n");
     fileOut.write("cd "+ itsFileLocation +"\n");
     fileOut.write("test.exe"+"\n");
     fileOut.write("exit"+"\n");
     
     fileOut.close(); // Close the output stream after all output is done.
    } catch (IOException e1) {
     e1.printStackTrace();
    } // Create the Buffered Writer object to write to a file called filename.txt
    Runtime runtime = Runtime.getRuntime();
    try {
     Process process =runtime.exec("cmd /c start C:\\test.bat");
    } catch (IOException e) …

在我的应用程序中,我需要捕获视频并在该视频上添加水印.水印应为文本(时间和注释).我看到使用"QTKit"Frame工作的代码.但是我读到该框架不适用于iPhone.

提前致谢.

我正在构建一个PHP脚本来缩小CSS/Javascript,这显然涉及从文件中删除注释.任何想法如何做到这一点？(最好,我需要摆脱/**/和//评论)

以下是我添加日历事件的代码.我想为EKEventEditViewController发送一个背景图片.我找到了这段代码

UITableView *eventTableView = [[editController.view subviews]objectAtIndex:0]; 

使用此代码,我能够为EKEventViewController设置背景图像,但它不适用于EKEventEditViewController.任何帮助是极大的赞赏.提前致谢.

     EKEventEditViewController *editController = [[EKEventEditViewController alloc] init];
//    UITableView *eventTableView = [[editController.view subviews]objectAtIndex:0];
//    [eventTableView setHidden:YES];

//    [eventTableView setBackgroundColor:[UIColor redColor]];
NSMutableArray *allViewControllers = [NSMutableArray arrayWithArray: editController.viewControllers];
NSLog(@"%i", [allViewControllers count]);
 UITableView *eventTableView = [[[allViewControllers objectAtIndex:0] subviews] objectAtIndex:0];
//    UITableView *eventTableView = [[editController.view subviews]objectAtIndex:0];
//    eventTableView.backgroundColor = [UIColor redColor];
UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"honeycomb.png"]];
eventTableView.backgroundColor = background;
//    [background release];
editController.event =  [eventsList objectAtIndex:indexPath.row];

我尝试在eclipse indigo中安装TPTP profiler.但它无法正常工作我收到以下错误.

Eclipse TPTP不支持您的平台.集成代理控制器将被禁用.要在支持的主机上进行配置,请在该主机上安装并使用独立的代理控制器.

我不知道如何在我的应用程序中检查我的sql内存泄漏.是否有任何其他Eclipse工具来检查内存泄漏.我想分析我在Tomcat中托管的web应用程序.

提前致谢...

我正在开发一个iphone应用程序(sdk 3.1.3),我已经添加了corelocation和mapkit框架.我使用了iphonesimulator包,但是使用'相对于当前的sdk'添加它们.当我在iphone simulatore中测试我的应用程序时,一切正常.但是当我切换到iphone设备3.1.3时,我收到2个警告和4个构建错误:

警告:

.../corelocation文件不是必需的体系结构
.../mapkit文件不是必需的体系结构

我右键单击mapkit框架包,检查获取信息,路径设置为:System/Library/Frameworks/MapKit.framework

我有基本的iphone开发知识,但我不知道问题是什么...有谁可以帮助我？

映入眼帘,

如何获得当前的经纬度

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation*)newLocation fromLocation:(CLLocation *)oldLocation {

} 

使用这种方法

如果我使用这个函数,我需要移动多少距离....这样这个方法将由corelocation框架调用或者我可以调用这个函数programmatic ....

我正在尝试构建同步图表但水平对齐,我是基于它做的

http://www.highcharts.com/demo/synchronized-charts

我使对齐水平,现在图表不同步

/*
The purpose of this demo is to demonstrate how multiple charts on the same page can be linked
through DOM and Highcharts events and API methods. It takes a standard Highcharts config with a
small variation for each data set, and a mouse/touch event handler to bind the charts together.
