random number generator

This software can generate random numbers to help teachers randomly call rolls and bosses assign tasks!
Reason for creation: On a certain day of a certain year and a certain month, I saw a tool [Random Number Generator]
Because it is a beta version and has not been updated, there are many errors after use. From time to time it will make an error and exit. So I thought: It is not difficult to generate pseudo-random numbers, how can I make it like this? I might as well make one, so I did it.

​

Press [Draw(1)] to draw the first random number!
Press [Temporary Save] to save the data into the temporary storage area, and press [Show Temporary Storage Area] to view it!
Right-click on the interface and select [Settings] to extract the range!

This software has an exclusion function! It is guaranteed that the specified number will not be drawn!
Right click on the interface to pop up the menu! Select [Settings] to set it up!
Note: This software excludes 25 and 26 by default. These two numbers have a certain meaning to me.

This software has shortcut key function! The program can be called up at any time in any situation!
For example: you can call this software to answer questions when playing PPT.
Right click on the interface to pop up the menu! Select [Associated Shortcut Key] to set it.
Shortcut key: Ctrl+Alt+R

This software has a voice function, which can read out the extracted numbers while extracting!
Right click on the interface to pop up the menu! Select [Settings], then select the [Color Color and Voice] tab to set it up!
Supports Chinese and English reading!
The English pronunciation requires the [Sam] library of Microsoft [Microsoft TTS Speech Library]!

Version:
Does 1.0 have multi-user functionality other than the random number generator? (Too much trouble!) Everything else is due to. Comes with a quick random number (can quickly name the PPT!)
1.1 Changed some small details!
1.2 Official release version Corrects program logic, fixes discovered errors, and resolves false positives! Add shortcut key function! Because of my carelessness, there is a big mistake in this version
1.3 Fix major errors in 1.2 and add inline help. The number that can be drawn at one time is increased to five. Rewrite the configuration module. Ensure that the numbers extracted each time are not repeated.
1.4 Fix possible minor bugs. The random number font scales with the range of numbers. The color of the random number font can be changed.
Added voice function: ①Chinese: female voice ②: Microsoft sam, requires Microsoft TTS voice engine library.
1.5 Fixed errors in the staging area. Change icon. A small improvement!
