What's the ListCtrlEx like drawing in the list item?-CodePudding

Trouble you ask next, in a recent ListCtrlEx (work demand, must use this class), should derive from ListCtrl, who can give me an example, tell me how to use ListCtrlEx one row in the list to determine a column in the bitmap ICONS or draw a picture? http://www.cnblogs.com/dlbrant/archive/2009/02/17/1392597.html is the online source code, I put the source code ListCtrlExDemoDlg. OnInitialDialog made a change in the CPP, and add the function InsertPic, specific content you can check the following code, compile environment is vs2010, but always couldn't draw the image, and is my code has a problem? I don't know how to return a responsibility? Please help me have a look at, thank you

Did you add imageList ListCtrl

CodePudding user response:

Uh huh, add the image list, I forgot to write another function

CodePudding user response:

Uh huh, add the image list, I forgot to write another function, writing in the following, don't know writing right

I'll rearrange the code, convenient ace to help me have a look at:
