I have a database that logs certain events on my simulation. I need to create a timeline using VB then get the events from the database and plot them according to the log time that is stored in the database.
eventually the timeline will contain all the events according to the log time in the database and they will have details on each time plot.
Any idea how to start? was looking at MSchart but not something that i have in mind.
First put the data from the database in an array.
With this data You can write the code for the visualization of Your own chart layout.
Some questions to start:
Q1 Is it possible to attach in Bytes a GIF file or screen capture (a simple sketch) of the layout You want to see so we can have an idea in which direction we have to think?
(I have attached an example created with Paint).
Q2 Is it possible to attach an example of the data ?
Is it text ? how much char's,...
Q3 Must all the data be visible at once or if the mouse moves over the data-points, ...?
I have googled and found nothing we can use.
To build a custom timeline is not such a big deal: analyze how You want it and calculate the points of the elements(lines, datalabels,...) .
I have done some brainstorming (maybe more storm than brains) but anyhow, we must start with some questions:
Q1: is it necessary to have a horizontal timeline?
Because a vertical one has better possibilities for setting the labels (see attached GIF).
Maybe no need to zoom to read the data?
Q2: How many datalines are there mostly in a timeline ? 10 ? 50 ? 100 ? 200 ?...
Q3: Are the coordinates of the timeline always the same:
From 8:00 to 17:00
Or are they fluctuating:
once 8:00 to 17:00
next 9:30 to 18:30
next 1:00 AM to 9:00 AM
next 22:00 to 7:00 AM next day ???
Q4: In the data, the time is represented by "8:01:050".
I suppose that 8= hours, 01 = minutes and 050 are thousands of seconds ???
Is it necessary the work with 1/1000 of a second ?
It can be set in the label but I suppose it's not relevant for the timeline?
Calculating the coordinates on hours and minutes will be enough ?
Q5: I have placed the data in a textfile for myself for developing and testing the program.
At startup I read the data in an array.
I suppose it's no problem for You to read the data from Your database into the array so we can work further in the program on the data in the array? (see attachment)
These are the first tests.
It's with a vertical scale but for a horizontal one it's only calculating the LEFT instead of the TOP of the elements.
The datalabels are still overlapping but with a zoom of the hole scale can solve that.
Whats Your suggestions and remarks ?
I have not really looked at your codes yet. appreciate your help =).
My way of doing:
its not efficient coding but i will just use it if it works.
i load my data into a sqlDataAdpater. Then create a panel to act as the timeline. i did a difference between the last time and the start time, then divide them by the width of the panel. now i will have the number of seconds represented by each pixel. so buy doing some calculation i draw my lines and plot the events on this time line.
still working on the zooming in of the information. will post some pics when available. Thanks once again.
No need to ZOOM (resize) the label!
Just use two labels: a label Minimum size with nothing in and a Label with all the data.
Just flip-Flop on "Visible" beween the two labels.
The user gets the impression that it zooms!
See attachment:
- Click on the labelData or LabelDataMin with the right mouse button to +zoom or -zoom.
- Click with Left mouse button on the full sized label (LabelData) and drag-drop it to replace the label.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...
Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
