Open the jpg file containing the date and time.

[mucitbey]

Hello, I needed your help with a code I wrote.
The problem is; based on the data read and the date and time of the file to be opened. There is a difference of 1 second (very rarely 2 seconds) between the data read and the file to be opened. Let me exemplify like this.
The problem "0010171588\07.08.2023_17.32.40.jpg" pops up. but sometimes the file name to be opened can be "0010171588\07.08.2023_17.32.41.jpg" due to the network write delay, then the file cannot be opened. (although very rarely it can be 010171588\07.08.2023_17.32.42.jpg)
 

GUICtrlCreateGroup("QUIT PHOTO", 455, 280, 330, 260)
GUICtrlSetFont(-1, 10, 800, 0, "Righteous")
$Tim02a = StringRegExpReplace($Read24, "\A(\d*):(\d*):(\d*)", "$1.$2.$3")
$Tim02b = $Read21 & "\" & $Read22 & "_" & $Tim02a & ".jpg"

If FileExists($Tim02b) Then
    $Pict02 = GUICtrlCreatePic($Tim02b, 460, 295, 320, 240)
    ConsoleWrite($Tim02b & @CR)
Else
    Local $Tim03a = StringRegExpReplace($Tim02a, "_(\d+)\.", "_" & IncrementSecond("$1") & ".")
    $Tim03b = $Read21 & "\" & $Read22 & "_" & $Tim03a & ".jpg"
    $Pict02 = GUICtrlCreatePic($Tim03b, 460, 295, 320, 240)
    ConsoleWrite($Tim03b & @CR)
EndIf

Func IncrementSecond($match)
    Return "_" & (Int($match) + 1) & "."
EndFunc

To get help you really need to ask for help in a better way. We can't simulate anything with your code in this state neither to understand what is your actual issue.

How often are the files written? If it's greater than a few seconds, maybe build in a few seconds of leeway for the filenames, like +-2 sec?

     Data is not generated in an orderly fashion. The data is recorded in an ini file with date and time data, and when this process is completed, a jpg file taken with the webcam is recorded. However, when I want to match the ini file with the jpg data, I cannot match because of the difference in the file name between the read data and the data to be retrieved, since the jpg file is usually written with a 1-2 second delay, although not always. I hope I was able to explain the problem.

For me it's not clear at all. I got the part where you get some screen captures from your webcam and save them as jpg files and the name of each file contains date/time information. Where does this +- delay come from?

When the record is entered, it first writes the data as Date (07.08.2023) and Time (17.32.40) in an ini file, and takes a picture of the document with a webcam after saving it (07.08.2023_17.32.41.jpg). When the webcam creates a file, it records with a delay of 1 second. therefore, while matching the image file with the data in the ini program (07.08.2023) and Clock (17.32.40) it tries to merge and open the jpg file. But it can't find the file because of the delay.

I also save the image with this udf.

Why don't you save the timestamp in the JPG itself?

[junkew]

I think you are saying that the actual filename is created by the webcam software and you are not in control of that file generated.

Some things you could try

Take webcam snapshot before writing ini file

Take a directorylist and sort that on time and see if latest matches to your timestamp.

[jchd]

Convert the date in .ini into a sortable format (y-m-d h:m:s) use _FileListToArray to list files then convert similarly dates in filenames into the same sortable format. Then it's easy to find a file dated within few seconds of the ini date.

Things would be much simpler if a standard (sortable) datetime stamp were used!

[junkew]

_WebcamSnap($sId, $sFile)

Seems you are in control of your filename. Show your code and make sure you give a filename equal to what you write to the ini file.

Hello,
First of all, thank you all for your help and guidance. I solved the problem in a different way. I went back to the codes I wrote first, there was something I missed at first, when I fixed it, the problems were solved. Therefore, this procedure is no longer necessary. In short, my mistake was that I tried to write the ":" character in the filename.

That creates an ADS (Alternate Data Stream) "under" the main filename (provided the file system of the device is NTFS). https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-fscc/e2b19412-a925-4360-b009-86e3b8a020c8
