I could reproduce the scenario which causes this problem and it is such a strange and tricky .
https://www.youtube.com/watch?v=IaxZ...ature=youtu.be
I was limited to 15 minutes of recording so , there is an uncompleted test result at the end of the video but it should be enough to make the point clear for now .
Summary for video :
The scenario :
1- Add a new user control
2- Place normal textbox or any VB6 intrinsic controls in the user control .
3- Place any VBCCR control in the user control
4- In the UserControl_Initialize event , add these lines of code .
Lets say you used a VB intrinsic Textbox and a VBCCR CommandButtonW . Add these lines
5- The problem happensCode:text1.text="Hello" commandbuttonw1.caption ="Hello"
6 - Uncomment the code , The problem now disappears .
7 - Put the following code in the same event
8 - With this previous case , the problem does not happen .Code:Dim s as string s= "Hello , I prove that not all code causes the problem , It is only for the code that draws an item in the user control"
More details and tests are found in the video for tests on the ComCtlsDemo project
Thanks everybody for your help and sorry for bad English .
