[ad_1] First – find out how to run this code under a debugger. Then it’ll just stop on the line where the segfault occurs, which should make it more-obvious what the problem is. Given that you’re saying “segfault”, it’s probably safe to assume you’re running some unix-variant, in which case, “gdb” is probably your debugger. … Read more

[ad_1] Your pop function destroys the entire stack. It deletes the tmp node (by calling the Stack destructor), which still points to the new next. And since the Stack destructor calls delete on next, you get a mess of multiple destructor calls on the same objects. JMA beat me to it by a few seconds, … Read more

[ad_1] There are simply too many questions here. I tried Electron Js to make application, but the problem is that, it takes extra memory in machine. While the memory consumption of electron application is usually larger than highly optimized native applications, it is comparable to running chrome standalone. So switching from electron to a node … Read more
[ad_1] This is a subjective question. Personally I would tend to agree that having class here at all is poor form, and typename should have been the only keyword allowed. But that’s just my opinion. Perhaps this usage of class will be deprecated in the future; perhaps there are sufficient people who like to write … Read more

[ad_1] I would add a gestureRecognizer to each imageView. The function called by the gestureRecognizer would then change the image on the “big picker view”. There is no built-in way to get the image name that the user chose. If you really needed this, then you could sublcass UIImageView and add a fileName property. @IBOutlet … Read more
[ad_1] I think the issue is that you have an extra space after the inserted text in the SQL. This means that you are effectively searching for “lblheader.text ” (with a space after it) everytime, which I doubt is what you want. In the SQL statement , change LIKE ‘%”+ lblheader.Text +” %’ “; To … Read more
