CodePudding user response:

My program consists of three parts -- Fromfile import images, and then through the thread of image processing, with deletefile finally removed the original, but now the problem is not delete files and GetLastError returns 32. Seek the solution,

 m_pSelectedImage=Bitmap: : FromFile (filePath. AllocSysString ())//import images, filePath as the path to the file; 
. 
M_hThreadTools=CreateThread (NULL, 
0, 
RunImageToolsThread, 
This, 
0, 
& M_dwThreadID);//create a thread 
. 
The DeleteFile (filePath);//delete files

First of all, which process is confirmed in take up the documents?

Turn off your application, use resource managers try to delete files, if can be deleted at this time, your program opens the file, not closing DeleteFile failures,

CodePudding user response:

FromFile takes up the file, so I can't delete,

Have you release the Dispose?

Are the forms of pointer call
For example, to get the image of RGB values

 
LpParam CImageView * pView=(CImageView *);//get the current view 
PView - & gt; M_pSelectedImage - & gt; GetPixel (x, y, & amp; Color);
