How can I use a progress bar in objective c mac
How can I use a progress bar in objective c mac? I have a code that downloads a file and I want to be able to let the progress bar increase by 1. A bit further on the code (to download the file) it needs to increase again. And so on...
My code
-(IBAction) downloadButtonPressed:(id)sender;{
//get the path to the image that we're going to download
NSURL *url = [NSURL URLWithString:@"https://www.dropbox.com/s/l6o07m48npxknt4/Cluedo.zip?dl=1"];
//get the path to documents folder where we're going to save our image
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *DocumentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [DocumentsDirectory stringByAppendingPathComponent:@"Cluedo.zip"];
//Download the file to memory
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error = nil;
//Save it on the Documents directory
[data writeToFile:filePath options:NSDataWritingAtomic error:&error];
NSFileManager* fm = [NSFileManager defaultManager];
NSString* zipPath = filePath;
NSString* targetFolder = @"/Applications"; //this it the parent folder
//where your zip's content
//goes to (must exist)
//create a new empty folder (unzipping will fail if any
//of the payload files already exist at the target location)
[fm createDirectoryAtPath:targetFolder withIntermediateDirectories:NO
attributes:nil error:NULL];
//now create a unzip-task
NSArray *arguments = [NSArray arrayWithObject:zipPath];
NSTask *unzipTask = [[NSTask alloc] init];
[unzipTask setLaunchPath:@"/usr/bin/unzip"];
[unzipTask setCurrentDirectoryPath:targetFolder];
[unzipTask setArguments:arguments];
[unzipTask launch];
//[unzipTask waitUntilExit]; //remove this to start the task concurrentlyYour code really isn't suitable for a progress bar, not a real one anyway. Your code will spend about 99.9% of its time in the method "dataWithContentsOfURL:url". That is not a method you want to use in the real world. It is only for demos or proof of concept exercises. All network operations should be asynchronous. That gives you the ability to gracefully recover when there is a failure and also to do fancy things like display a progress bar and tell the user when the download is complete.
Once you get the asynchronous download logic working, then you can worry about the progress bar. The first thing you will need is the size of the file. Without that, all you can ever do is an indeterminate progress bar or spinner. If you have the size of the file, then you can keep track of how much of the file you have downloaded and update your progress bar with the percentage complete. Make sure to throttle it to no more than incrementing by 1% at a time. Otherwise, a large file or a file transferred in many small chunks, would waste too much time updating the progress bar for no change. -

Seeking in videos using the progress bar
Ever since the 2.0 update, seeking using the progress bar seems very sluggish, far from the smooth experience I had using the 1.1.4 firmware. The playback seems to snap to certain points and fast forward to the point I seek to. I updated to 2.0.1 today hoping this issue would be fixed, but not yet. Anybody else experiencing this?
mine is even worse, after the 2.0.1, video playback is broken. There is no video!!!! but there is audio. This apply to any online video as well like youtube. any facing the same problem? How can i restore to 2.0?

i have 5 html pages that share a common header, footer, and sidebar. how do i use my nav bar to change the content of the body without duplicating a lot of code? thank you!
i inherited the website. It’s for a non-profit and is not very
sophisticated, and neither am I in webdesign. It currently has multiple
pages that are identical except for that body section, so whenever i change
the navigation (in the sidebar) I have to update every html page. I want
to have one basic page, and just call in the different body content based
on the link the user selects from the nav bar. How can i do that using a
script? i am using Dreamweaver.
~ in love and light ~

How to make use of adjacent data elements within the same buffer
Hi,
Does anyone know how to make use of adjacent data elements within the same buffer? To make my question clearly, I would like to give you an example. In my application, I set "sample to read" as 10 which means at each loop 10 data samples will be taken into a buffer. Now, what I would like to do is to do some calculations on adjacent data samples in same buffer. I tried to use "shift register" for this, but it seemed to me that it only can deal with the calculation between data from adjacent loops. In other words, it skips 9 data elements and take the 10th one for the calculation.
Here I also attach my VI showing what I did.
Thank you very much in advance,
Suksun

wheel_encoder_1.vi 98 KBHi Suksun,
I hope you'll forgive me for distilling your code - mainly to understand it better. I tried to duplicate your logic exactly - which required reversing the "derivatives"-array before concatination with the current samples array. As in your code, the last velocity is being paired with the first position. If first velocity is really supposed to be paired with first position, just remove the "Reverse 1D Array" node.
cheers

Isn't this what you want?

Raj.SHi Raj
Function Modules
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the Function Builder.
The Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed.

You can execute function module in SE37ie you can perform the activiites defined in the function module by executing it.
By deleting BOM you mention the FM name in se37 and execute. In some function module it will ask input parameters as developed in the program , you have to give the input parameters and execute. -

How to make use of 'Icon Name' in Logical link?
I see the option 'Icon name' in 'define logical links' in SPRO. It does not however has an F4. I tried giving the name of image in the relevant skin. But no image appears besides the logical link. Is there something else that needs to be done to get an image besides workcenter link? How to make use of this 'Icon Name' in logical link?
Hi,
i guess this icon_name is not possible for every skin in CRM70.
We use nova skin - here it is not possible.
With default skin i saw icons for example on the salespro startpage.
Kind regards

You can reuse the packages in /var/cache/pacman/pkg/ on your Arch32.
You can use these saved packages in a 32bit chroot ENV on your Arch64. Just pacman -U all of them. -
