The attached sample program has an incomplete dialog window. It's just to demonstrate a custom edit control.
The dialog has two edit controls. One is a custom control derived from CEdit, and the other is a regular CEdit control. The regular control shows up.
I tried adding OnDrawItem after modifying the style to be owner-drawn, and that method is call. It's still not displaying anything. That code is currently commented-out.
I'm not sure what is wrong. I suspect it might be the wrong rectangle when I create the window, although I've played with that to no avail.
I have looked at the CTRLTEST Microsoft example.
Note, the commented-out OnDrawItem method in the dialog class is to draw a button, and the code was copied from a codeproject project. I just wanted to see something displayed.
I have code in a zip file to upload. Hopefully a way to upload that code will appear after I submit this question.
Again, I had to use tags that don't apply to get three tags. The only one that applies is C++.
Could you provide your code without any privacy？
I recommend checking the Custom Control properties, Property whether a control class is filled in.
JunjieZhu-MSFT - Thank you. I tried to upload a zip file, and it was too large - a bit over 200KBytes.
I then tried to post the code, and failed. The class is set to "EDITCUSTOM" which is the name I registered for this test code.
This is the relevant section of the RC file.

I tried to post most code, but exceeded the character limit. Is there a place I can email the zip file. It contains only source code.
I clicked the paperclip, however, I am not able to upload a text file that is only 11.5 Kbytes long.
When I click the Upload button, nothing happens. I'm not sure how to proceed.
You can share your code using GitHub. Make sure that no company secrets, personal privacy Or other inconvenient information are involved in the shared code.
The code is here:
https://github.com/mendobar/GenericMDIApplication
Again, this is not a complete application. For example, I never added the OnOK or OnCancel handlers to the dialog. I'm just trying to get the custom edit CEdit-derived control to show up. A regular CEdit control in the diaog does show up.
Thank you for your help.
The initial code had several issues. I made a number of changes to get it working and inserted some comments. In addition to the use of the custom control in the dialog template I also showed creating it dynamically in the application's About dialog.
The revised VS2022 solution can be obtained from OneDrive at https://1drv.ms/u/s!AmnqrCFBv4nDgh-jPL4Fd335LpQm?e=pobJts
Thank you.
I changed the RegisterClassWindow function to a static function before sending the code, and forgot to change the calling sites. I feel stupid about that.
Otherwise, I had no idea how to solve this. I didn't realize the needed modification to the RegisterClassWindow function, nor did I realize that OnCtlColor would not be called. I did use reflection with controls a very long time ago. I've forgotten most of that.
Thank you very much!
You're welcome. Glad to help out.
