Transgui: Adding date column throws error

[cybersteel8]

1. Windows 10 Enterprise x64 v10.0.17134
2. Transmission 2.92 (14714)
3. transgui-5.16.0-i386-win32

I am adding a new column by right clicking on the columns in the torrent list and clicking Setup Columns. The error is throws whenever a date column is added (Added on, Completed on, Last Active). The error that appears is "Could not convert variant of type (Null) into type (Int64)". Clicking OK terminates the application.

@PeterDaveHello, what will happen now? Will you compile a separate version?
(The version displays the line number with the error).

I can't reproduce this error.
Downloaded 5.16 and when I add a date column is all fine.

Windows 10 Home x64
Transmission 2.84 (14307)
TransGUI 5.16.0

I said that some mistakes are not repeated. Therefore, it is necessary to configure the compilation to display the line number with an error (enable debug flags).
But for us the main thing is to have a beautiful source code (it's sarcasm).

[cybersteel8]

I have investigated the issue a bit further and it appears to be related to the privileges of the application, not the column itself.

When I start transgui.exe normally and I add the column, the error appears but if I wait a moment longer the dates fill in on the column, despite the error message being displayed. Clicking OK still terminates the application.
But, if I start transgui.exe by right-clicking and selecting Run As Administrator (and pressing Yes at the prompt), the error does not appear and the column is added without a fuss.

Additionally, the column is not retained on application restart in non-privileged mode. When I run as administrator and add the column, the column remains when I restart the application.

EDIT: This appears to be inconsistent. Currently the error is occurring even after running as administrator.

@cybersteel8
Can you try delete your transgui.ini file and then place an empty 0 (zero) byte transgui.ini in the directory where you have transgui.exe installed. Then you'll need to start from scratch transmission-remote-gui configuration, so you could try copy transgui.ini to install directory and delete from original location instead.

[antekgla]

It is like @cybersteel8 says... your TransGUI dont have permitions to write transgui.ini
Where is located your transgui.ini ?

[cybersteel8]

@cfpp2p I currently have my transgui.ini file inside the same directory transgui.exe exists, which is in my C:/Users/[username]/Downloads folder.

I backed up my ini file and completely removed it from that directory and created a new zero-byte file. When launching transgui, I provide my transmission connection details and all works as normal, however the error still appears when adding that column. I checked the transgui.ini and it is now filled out with all the configuration settings, including my transmission connection details, so it appears to have written to the ini file correctly.

Also, the behaviour is very inconsistent - I ran as administrator, and I attempted to add the column, and it worked. In the same session (I did not exit transgui) I removed the column and added it again, and the error came up. 99% of the time it doesn't work, even when run as administrator.

transgui.zip
Try this version. If there is an error, see the file crashreport.txt.

thanks!This is useful information. It is now clear where to look for a mistake and set a defense.

[cybersteel8]

I am happy to help if you require me to perform more testing, or if you need more information.

[leonsoft-kras]

Are all updates installed in the OS???
An error occurs somewhere in the MouseMove function code (Pascal / Lazarus).
How this relates to the date is not clear.

[cybersteel8]

I can't know for sure. I provided the build number of my Windows OS in the OP, what is the latest build number from Microsoft?

[cfpp2p]

I can't reproduce the error. Try setting NullStrictConvert to false in vargrid.pas

Try
transgui-5.16-setup.zip

[leonsoft-kras]

my version: win10, version 1803 (assembly 17134.523)

There are test results for the new version of TRGUI?

[cybersteel8]

Try
transgui-5.16-setup.zip

This one appears to work. I cannot reproduce the error using this version.

[leonsoft-kras]

fine. I will make a correction to the main code in the evening.
