InstallShield itself does not contain a textbox of the password type. To solve this problem, refer to the following method:
1. Download a software similar to C ++ resource editor. Here I recommend that you use excoder.
2. Open _ isres. DLL, which can be found in <installation directory> \ redistributable \ compressed files \ 0009-English \ intel 32, where 0009-English is the language pack. If you have a Chinese Language Pack, you can find this file in the corresponding directory;
3. Find 10102 on the left side, edit the style attribute of the dialog box, and select the password.
4. You can see that the *** style is displayed in the textbox;
5. A prompt is displayed when saving the file. Do not change the file size;
6. Save and exit;
7. Rebuild your project file.
Since I have not used InstallShield and this tool for a long time, I wrote the above based on my impressions. It may be different from the actual operation process, but it is similar. Please test it and modify _ isres. remember to back up the DLL.
