Program in the process of debugging, abnormal: when postmessge function called windos has been spatially-integrated SVS. Exe triggered a breakpoint, the reason may be that the heap is damaged, it shows that spatially-integrated SVS. Exe or its load any DLL have bugs,

Great god under the analysis of reasons, very grateful!

CodePudding user response:

Direct PostMessage (WM_DISPLAY_IMAGE, 0, 0) a try? Not through the Form calls

CodePudding user response:

You this is in open thread, rather than in the main thread?

CodePudding user response:

See F5 to run, the interrupt stack hang bai, estimate is to obtain the image is the buffer to burst,

Collapsed in the pop-up dialog box, press the corresponding button to enter debugging press Alt + 7 key to view the Call Stack, namely "the Call Stack" from the inside to the following out of from the inner to outer function Call history, double-click a row to the cursor to the Call of the source code or assembly instruction, don't understand when double click on the next line, until we can read ,

Determine whether cross-border access, can be in after the last element of an array of the corresponding address set read and write data breakpoints, if the address corresponding to other variables interfere with the judgment, can be more declare an array element, and set the read and write data breakpoints on the corresponding address of the more elements,
