Hey, there! recently working with my winform project, I came across a problem, I created a Data table programmatically and gave one column of it, the path to an image. I have done it many times, and it worked all the times before, but this time, the image didn't show, instead it said: "string.byte()" or … Continue reading [.NET] DataGridView not showing the image from Data Table
[VB.NET] DataGrid view slow drawing
Today, working on one of my projects, I came across an irritating problem of .net Control (DataGridView). even with 53 records, the control was drawing very slowly that I could see it stuttering, I thought of enabling "Double Buffer" which I usually do for my forms, but unfortunately, Microsoft doesn't give this feature for DataGridView … Continue reading [VB.NET] DataGrid view slow drawing

[CodeChef Problem] Snake Procession
The annual snake festival is upon us, and all the snakes of the kingdom have gathered to participate in the procession. Chef has been tasked with reporting on the procession, and for this he decides to first keep track of all the snakes. When he sees a snake first, it'll be its Head, and hence he will mark a 'H'. The snakes are long, and when he sees the snake finally slither away, he'll mark a 'T' to denote its tail. In the time in between, when the snake is moving past him, or the time between one snake and the next snake, he marks with '.' s.
