Project attached, greatful for feedback if it works on all Windows versions. Building requires MasmBasic version 25 Feb 19 (http://masm32.com/board/index.php?topic=94.0)
Works on Windows 8.1
The background stretches and the foreground anim and bitmap image are not.
Thanks, Marinus. The stretching behaviour is by design, only the "fit" forces adjusting the size.
Hi JJ
not working here on Windows10
(http://i68.tinypic.com/2wfjzaf.png)
And, if i put the file on another directory, the gui opened, but without the image. This error came up "Could not open \Masm32\examples\exampl04\car\car.jpg for FileRead$ etc" (yes, car.jpg is inside the masm directory on my PC at: "C:\masm32\examples\exampl04\car\car.jpg"
Hi JJ. Perfect in 7-32

Hi Guga,
Apparently something blocks the download of the http: gif. It works on wifee's Win10 machine, but security settings are not that strict 8)
Re car: Did you try from drive C: or from another drive? The program tries to load
?:\Masm32\examples\exampl04\car\car.jpg, i.e. from the
current drive.
@HSE, thanks, good to know.
HI JJ
I tried both ways. car.jpg is in drive "c" (on the directory where masm ins installed)
I tested it putting GuiImageDemo.exe in masmbasic directory "ascuser" and the error showed up. Then i tried in the main masm directory "c:\masm32', and the main "c:\" and the error happened again, then i tried on other drives "D", "E", "H" and the error in the image showed up too.
Windows10 is a true hell. I had some problems of that with RosAsm too, when trying to close some apps after debugging it.
Thanks, Guga. I have no idea what's happening. Can you please test the attached debug version?
NICE JJ!
I used to first version, without any issue
Don´t know why windows10 is doing this with the app when i put it in the masm32 directory or in masmbasic one. You other files works ok.
To make it work, i did 2 tests:
1st) Extracted the file to drive "D:" and opened from there:
The gui showed up, but an error came out:
Quote"0 01.01.1601 00:00:00
test $f$:20 0 <not a pointer>
## line 11: image could not be loaded, Ok
Could not open
for FileRead$ etc.
## line 15: image could not be loaded, Ok"
After i clicked on "Ok" (After the error message), the gui appeared, but the image of the pink panther just was displayed after i resize the window.
2nd test) -
Strangely, the file loaded Ok, when i opened directly through the zip file. Windows saved it on the temp directory.
The error above was still there, but this time, the pink panther image showed up right in time. I mean, when the gui was displayed without i having to resize the window
Btw, the same error msg came up, but no messagebox.
"22115 16.03.2002 03:41:38 \Masm32\examples\exampl04\car\car.jpg
test $f$:20 ÿØÿà
## line 11: image could not be loaded, Ok
## line 15: image could not be loaded, Ok"
01.01.1601 and not a pointer mean the car.jpg simply wasn't there - which is normal if the current drive does not have a Masm32 installation.
The "image could not be loaded" is GdiPlus stuff, probably because the download of one of the GIFs was not finished. Will investigate, thanxalot for the feedback :icon14:
Latest version - extract the exe to a folder that contains images. This one does not attempt to download images.

JJ,
Worked OK on my win10 64 pro but it showed a message box with an error about fileread$. The resizing works fine, no flicker and seemed to be fast enough without any lag.
> extract the exe to a folder that contains images
Hutch,
Does the folder contain any images?
No, I did not realise at the time that I should have got the images from the earlier post. The resizing and stretching worked well on my box, very smooth and no flicker.

Interesting JJ!
CO2 concentration follow temperature better than emission. Except before 1900, but perhaps there is estimation problems.
Temperature and CO2 source?
@HSE: I must try to reconstruct where my data come from, e.g. https://datahub.io/core/global-temp
Don't jump to conclusions about the hen & eggs problem - the overlay plot just normalises the three datasets. It is pretty evident, though. There is a known irregularity for global temp in the 1940s and 50s, I wonder whether they eventually agreed on the cause (volcanic activity?). Here (https://www.newscientist.com/article/dn11639-climate-myths-the-cooling-after-1940-shows-co2-does-not-cause-warming/)is what the
New Scientist writes about it:
QuoteThe sudden drop in temperatures in 1945 now appears to be an artefact of a switch from using mainly US ships to collect sea surface temperature data to using mainly UK ships. The two fleets used a different method.

Source (69 lines of code) and data are attached; building requires MasmBasic version 10 April 2019 or later (http://masm32.com/board/index.php?topic=94.0).
Grateful for feedback if it looks good on other Windows versions, too (screenshot is Win7-64; WinXP works, too).
If I find the time, I will post a step-by-step example soon. The attached GlobalWarming.asc uses three different methods to load the data into numeric arrays, here are two:
StringToArray 100, gem() As REAL4, staHasText ; ** emissions ** (ID100 is global_emissions.tab in resources)
UnzipInit 103 ; resource ID for annual_CO2_concentrations.zip
StringToArray UnzipFile(0), x$(), csv ; ** CO2 concentration ** (resource zipped for smaller exe)
UnzipExitDepending on the format of the data (strings, well or badly organised, REALx binary data), there are several options, in particular StringToArray (http://www.webalice.it/jj2006/MasmBasicQuickReference.htm#Mb1130) and ArrayRead (http://www.webalice.it/jj2006/MasmBasicQuickReference.htm#Mb1179).
Version 27 April 2019 (http://masm32.com/board/index.php?topic=94.0) features some simplification of the MakePath command. For details, click (in RichMasm) File/New Masm source and open the Gdi+ example.

Attached an example on how to use maps in a MasmBasic GUI program. Building requires MasmBasic of 2 May 2019 or later (http://masm32.com/board/index.php?topic=94.0).
If you own a shapefile that you would like to convert (or you want to use one obtained here (https://wiki.openstreetmap.org/wiki/Shapefiles#Download_shapefiles)), PM me.
(http://www.webalice.it/jj2006/pics/MapsInMasmBasic.jpg)
The bare minimum source for displaying the map looks as shown below. The attached source is slightly more complex (25 lines), since it contains code to react on user clicks into one of the countries.

ArrayLoadMap 0, "Europe" ; Europe.dmi and Europe.map in \Masm32\MasmBasic\Res

PaintMap RgbCol(127, 127, 127), lines=2 ; map with grey borders 2px thick
ArrayPlot exit, "Europe"
GuiEnd
New MasmBasic version uploaded (http://masm32.com/board/index.php?topic=94.0), with some improvements under the hood. Data plotting uses now GdiPlus and anti-aliasing.

The grid itself can be drawn if you have the exact dimensions of the window, If you take a GDI+ clock from another topic as an example, you can draw a certain number of spheres with different sizes, and then calculate the connection lines. I think it will work :azn:

my unfinished vision of a polar rose could be
I have tried to draw different things with gdi
Seems everything but setpixel appears fast despite loops calling many rects ,I suspect its drawn with or without hardware acceleration on a backbuffer so it appears to be drawn instantly
