Build STR# 10135, 18/19 Folders
Hey All, Windows 10 - 4D v17r4 I just noticed that the build of an engined version of my app creates two folders (as it should) named: STR# 10135, 18 -> Appname.4dbase -> includes the .4DC/.4DIndy files STR# 10135, 19 -> Appname -> includes executable Is this related to the application build XML or JSON file? I will need both of these folders as part of the “App”. I’m so use to a Macintosh application or running a 4D Server where access is via a client. And I haven't had to create a standalone app since DataPulse/StructurePulse 10 years ago. I’ll be researching in KB for best way to organize these windows folders, to using the build file (xml or json), where to place the image, etc. A number of TN's but mostly from back in 4D 2004 days.

Re: Windows app 3-4 times slower
Hi Tom, I do have Parallels but it’s currently running windows 7 I think. I think it would be a good idea to get windows 10 and install it with Parallels and see how that works out. Like you say it would be a better comparison then. OTOH, now that I realize I have a slow laptop, it gives me a good testing machine to see how other with a slow computer will experience this app. Appreciate, John... > On Mar 8, 2019, at 3:39 PM, Tom Benedict wrote: > > Hi John, > > I don’t know whether anyone has already mentioned this, but you might > consider installing Windows on your MacBook Pro.

Dropbox Upload and Dropbox Download Methods
A few weeks ago I posted a message asking if anyone had written code to upload and download files to Dropbox. Got no responses other than “the API looks like it is easy to do”. Today I spent time writing a couple of methods to allow uploading and downloading files from Dropbox with native 4D commands using the Dropbox v2 API. And people were right, it was not too difficult. The v2 API is implemented very nicely and documented fairly well. I found a few documentation errors, but they were easily dealt with. 4D v17 provided all the commands needed to make it all work with very little code. Doing this with NTK would easily take 3 times the amount of code. My current needs are very simple. I want to upload a file to Dropbox and replace any existing file if necessary. Dropbox maximum file size for a single upload operation is 150MB. That’s more than enough for my needs. But if you want to upload larger files — up to the Dropbox API max size of 350MB — you’ll have to implement an “upload session”. Download requirements are also simple. Just download a file from a Dropbox path to a path on your hard drive. Dropbox paths are in POSIX format. The Dropbox v2 API uses OAuth 2, but that basically boils down to creating an “App” and getting an “access token” the you use with all the API calls. I’ll leave it up to you to go read the docs and set that all up. It’s easy. The code uses dot notation, but with a little work it could be ported to work with older versions for 4D probably back to v14. Code is cross-platform without any extra effort needed. Here is me giving back to the group so you don’t have to spend a day developing and testing code. If others implement more of the Dropbox v2 API, please post it to the iNUG to help others. // === // PROJECT METHOD: Dropbox_UploadFile // PARAMETERS: $0 = results object // $1 = dropbox access token // $2 = dropbox path // $3 = file path // DESCRIPTION: Uploads a file to Dropbox using the v2 API // Max upload size in a single transfer is 150MB. // https://www.dropbox.com/developers/documentation/http/documentation // CREATED BY: Tim Nevels, Innovative Solutions ©2019 // DATE: 3/8/19 // LAST MODIFIED: // C_OBJECT($0;$results_o) C_TEXT($1;$dropboxAccessToken_t) C_TEXT($2;$dropboxPath_t) C_TEXT($3;$filePath_t) $dropboxAccessToken_t:=$1 $dropboxPath_t:=$2 $filePath_t:=$3 // declare local variables C_TEXT($headerValue_t;$requestURL_t;$response_t) C_LONGINT($statusCode_l) C_BLOB($content_x) C_OBJECT($headerValue_o;$response_o) ARRAY TEXT($headerName_at;0) ARRAY TEXT($headerValue_at;0) // setup http header APPEND TO ARRAY($headerName_at;"Authorization") APPEND TO ARRAY($headerValue_at;"Bearer "+$dropboxAccessToken_t) // set upload header values APPEND TO ARRAY($headerName_at;"Content-Type") APPEND TO ARRAY($headerValue_at;"application/octet-stream”) APPEND TO ARRAY($headerName_at;"Dropbox-API-Arg") $headerValue_o:=New object(\ "path";$dropboxPath_t;\ "mode";"add";\ "autorename";False) // overwrite any existing file $headerValue_t:=JSON Stringify($headerValue_o) APPEND TO ARRAY($headerValue_at;$headerValue_t) // set url $requestURL_t:="https://content.dropboxapi.com/2/files/upload"; // load the file DOCUMENT TO BLOB($filePath_t;$content_x) // check file size If (BLOB size($content_x)>(1024*1024*149)) // over 149MB, too close to limit to try $results_o:=New object(\ "success";False;\ "statusCode";408;\ "errorMessage";"File is to large to upload in one piece") Else // upload the file HTTP SET OPTION(HTTP compression;1) // do compression HTTP SET OPTION(HTTP timeout;60*10) // 10 minute timeout $statusCode_l:=HTTP Request(HTTP POST method;$requestURL_t;$content_x;$response_t;$headerName_at;$headerValue_at) // build results object Case of : ($statusCode_l=200) // upload was a success $results_o:=New object(\ "success";True;\ "statusCode";$statusCode_l;\ "errorMessage";"File upload was successful") : ($statusCode_l=409) // endpoint specific problem $response_o:=JSON Parse($response_t) $results_o:=New object(\ "success";False;\ "statusCode";$statusCode_l;\ "errorMessage";$response_o.error_summary) Else // other problem $results_o:=New object(\ "success";False;\ "statusCode";$statusCode_l;\ "errorMessage";"HTTP Request failed"+Char(Carriage return)+Char(Carriage return)+\ $response_t) End case
Re: Windows app 3-4 times slower
Hi John, I don’t know whether anyone has already mentioned this, but you might consider installing Windows on your MacBook Pro. That would make it easier to compare apples to apples (ha! I made a joke!). Anyhow, you can use Apple’s Bootcamp to install and run Windows on your MacBook or you can purchase Parallels or VMWare then run Windows in one of those environments. You’ll have to purchase a copy of Windows too. At least then you’ll take the hardware out of the equation.

Re: Windows app 3-4 times slower
Hi John,
One more thing… That MacBook Pro has an SSD in it (Apple has not put spinny
hard-drives in their laptops since 2012.) If your Windows machine does not have
an SSD, that would make a HUGE difference.

Re: Windows app 3-4 times slower
Hi Ken, Yea I’m beginning to see that the windows laptop is a lot slower then the MacBook Pro. So maybe I do need a newer laptop just for testing purposes. Then I can see how fast it will be across a range of processors. I want to know what the potential user base will experience so I can frame the perception. And yes, RAM would definitely improve the overall performance. But I’ll put those dollars towards a newer one I think.

Re: Windows app 3-4 times slower
Hi John,
The i3 only has two physical processing cores, each of which may operate with
two logical processors. Logical processors running on one physical core are no
where as speedy as two physically independent cores. Also 8-GB of RAM vs. 16-GB
of RAM certainly will affect throughput.

Subject: Windows app 3-4 times slower
Hi All,
This App is running under both Mac/Windows 4D v17R4...
You might recall, a week ago or so, that I was soliciting help with creating an
engined based 4D App. I figured that part out (although certification later).
What I am finding baffling is how much slower the engine runs on windows versus
on my MacBook Pro. When I say slower I seeing the Mac being 3-4 times faster in
various scenarios.
Part of the speed differentials might be a special plugin that the App uses.
The plugin was created using Xcode for the Mac and Visual Studio (v15 I think)
for windows. I’ll have to create special test to compare and see. The SVG
drawing is slower; the searching in a database seems much slower.
A special search routine, which requires calls to the plugin, took 1 minute 4
seconds on the Mac and the same thing on window took over 4 minutes - compiled.
BTW, the same routine running as source on the Mac took 3 minutes 41 seconds
and on window took 10 minutes and 46 seconds (over twice as slow). Maybe the
windows version of the plugin (there’s both a 32bit and a 64bit) has some other
setting which can optimize it?
FWIW, I have been trying to get by using as much of native 4D as I can and as
little of the plugin as is required. I might have to reconsider this and move
some of this work from 4D into the C++ plugin since calculating in the plugin
it’s so much faster…
On the Mac side:
MacBook Pro (Retina, 15-inch, Mid 2015)
System Version: macOS 10.12.6 (16G1618)
Processor Name:Intel Core i7
Processor Speed: 2.8 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory:16 GB
On Windows:
HP Notebook x64-bassed PC
System Version: Windows 10 Home (10.0.17134)
Processor Name:Intel Core i3-6100U
Processor Speed: 2.30 GHz
Number of Processors: 4 logical
Memory:8 GB {not sure if I can add more?}
My past experience has been that it’s usually slower on the Mac and much faster
on windows. But these are different times. Both the Mac and Windows have
Bitdefender running for security. (It’s probable that there are other programs
running on windows I am unaware of).
This single user standalone app will be marketed to a client base which will
not have necessarily have the fastest equipment. So anything I can do - not
necessarily hardware based - to speed things up will be helpful.
For those of you who work on both modern Macs and Windows what is your
experience in terms of speed comparison?
When I move a database over from a Mac to a windows do I need to throw all the
indexes away and have them rebuilt? {I don’t think so since if it were running
via 4D Server wouldn’t be an issue}
Are there steps you’ve taken that sped things up?
I might have to work with 4D’s profiler and some other test to determine the
bottlenecks. Way too slow!
Thanks for your feedback,
John…

Re: Windows app 3-4 times slower
what is the drive in both. Perhaps Mac has SSD and windows has slow HD

Windows app 3-4 times slower
Hi All,
This App is running under both Mac/Windows 4D v17R4...
You might recall, a week ago or so, that I was soliciting help with creating an
engined based 4D App. I figured that part out (although certification later).
What I am finding baffling is how much slower the engine runs on windows versus
on my MacBook Pro. When I say slower I seeing the Mac being 3-4 times faster in
various scenarios.
Part of the speed differentials might be a special plugin that the App uses.
The plugin was created using Xcode for the Mac and Visual Studio (v15 I think)
for windows. I’ll have to create special test to compare and see. The SVG
drawing is slower; the searching in a database seems much slower.
A special search routine, which requires calls to the plugin, took 1 minute 4
seconds on the Mac and the same thing on window took over 4 minutes - compiled.
BTW, the same routine running as source on the Mac took 3 minutes 41 seconds
and on window took 10 minutes and 46 seconds (over twice as slow). Maybe the
windows version of the plugin (there’s both a 32bit and a 64bit) has some other
setting which can optimize it?
FWIW, I have been trying to get by using as much of native 4D as I can and as
little of the plugin as is required. I might have to reconsider this and move
some of this work from 4D into the C++ plugin since calculating in the plugin
it’s so much faster…
On the Mac side:
MacBook Pro (Retina, 15-inch, Mid 2015)
System Version: macOS 10.12.6 (16G1618)
Processor Name:Intel Core i7
Processor Speed: 2.8 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory:16 GB
On Windows:
HP Notebook x64-bassed PC
System Version: Windows 10 Home (10.0.17134)
Processor Name:Intel Core i3-6100U
Processor Speed: 2.30 GHz
Number of Processors: 4 logical
Memory:8 GB {not sure if I can add more?}
My past experience has been that it’s usually slower on the Mac and much faster
on windows. But these are different times. Both the Mac and Windows have
Bitdefender running for security. (It’s probable that there are other programs
running on windows I am unaware of).
This single user standalone app will be marketed to a client base which will
not have necessarily have the fastest equipment. So anything I can do - not
necessarily hardware based - to speed things up will be helpful.
For those of you who work on both modern Macs and Windows what is your
experience in terms of speed comparison?
When I move a database over from a Mac to a windows do I need to throw all the
indexes away and have them rebuilt? {I don’t think so since if it were running
via 4D Server wouldn’t be an issue}
Are there steps you’ve taken that sped things up?

bottlenecks. Way too slow!

John…
