Crosshair has a vertical and horizontal line to view the value of the axis. 1 Week Ago by PM312 i want to add Crosshair , a vertical and horizontal line to view the value of the axis is this available for charts in vb.net 2017. ![chart_2.png](https://static.daniweb.com/attachments/2/0ec00ac4dbe56443fdf35cb9868981b5.png) Re: Crosshair has a vertical and horizontal line to view the value of the axis. 1 Week Ago by rproffitt Given the **antipathy** towards AI here, all I can share is if you put "i want to add Crosshair , a vertical and horizontal line to view the value of the axis is this available for charts in vb.net 2017." into a chatgpt session, you'll find a solution in about 20 seconds. Re: Crosshair has a vertical and horizontal line to view the value of the axis. 1 Week Ago by rproffitt Sorry but I only have VS2008 and VS2022 now. But for a real-time crosshair that moves with the mouse, showing its position along the X and Y axis I asked ChatGPT and it appears to only need less than 20 lines of code that respond to Chart1_MouseMove(). Re: Crosshair has a vertical and horizontal line to view the value of the axis. 1 Week Ago by Dani The trick with AI is to give it very short bits of code to write at a time. If you ask it to write an entire mini-program that does X, it inevitably gets quite a few bits wrong, left out, etc. But if you ask it to write pseudocode first, and then for each individual method/function call, you carefully explain what you want it to do, what parameters… How to display chart with long X axis values without congestion 2 Weeks Ago by PM312 I have a candlestick chart with long list (data point) on X-Axis which becomes congested when loaded. How to show datapoint with sufficient space . Is there any container with horizontal scroll bar to display chart just like data is displayed in DataGrid view without reducing column width. ![Chartcandlestick.png](https://static.daniweb.com… Re: How to display chart with long X axis values without congestion 2 Weeks Ago by kinvieb Hi, My first and quick point of view is that if you have a chart with such a big amount of data points, there might not be a need to show all individual data points. For the axis values, you may just choose to show points at a given interval, to avoid the congestion. For the data labels, you can choose to show labels at particular points (like … Re: How to open an Excel Document in VB.NET 2 Months Ago by Pelorus_1 A Microsoft Excel document can be opened in VB.NET using the Microsoft.Office.Interop.Excel library. Using Workbooks.Open(), open the workbook, and then display the Excel window. Reference the Excel COM object in your project. Re: How to open an Excel Document in VB.NET 2 Months Ago by JamesMichaelm I see it's been a while since you posted, but I'm curious if anyone here has tried using the Open XML SDK instead of Interop or OleDb for reading Excel files. I found it faster and doesn't require Excel to be installed, though it can be more complex for writing. Wondering how others handle big Excel files or ones with tricky formatting? Re: How to open an Excel Document in VB.NET 2 Months Ago by PitSterw I've worked on something similar and found that using Microsoft.Office.Interop.Excel lets you open the file and loop through cells easily. Differential Directory, indexing method 2 Months Ago by xrjf **Features:** * Retrieves the differentiating bit of a key with respect to the previous one and stores only this position in the index. * With at most one single disk read, assuming the index is in memory, it determines whether the key exists or not. * The index is always sorted and therefore requires no reorganization. * Performance is … Re: Differential Directory, indexing method 2 Months Ago by rproffitt DiDi appears to be some China based UBER service but then again I can't find a question or much else to discuss here. Re: Differential Directory, indexing method 2 Months Ago by xrjf About DiDi DiDi (Differential Directory) was originally developed as part of my thesis project in the early 1990s. The name bears no relation to the more recent Chinese ride-sharing company. At the time, DiDi was a novel approach within its academic context, but a change in legislation unfortunately led to the closure of the school and the … Re: Differential Directory, indexing method 2 Months Ago by xrjf For example, as Donald Knuth points out in The Art of Computer Programming, the theoretical lower bound for comparison-based sorting algorithms is K × log₂(N). I developed a very simple method that matches this performance. However, DiDi goes far beyond: its performance is proportional to K × (maximum key length), regardless of the number of … Re: Differential Directory, indexing method 2 Months Ago by xrjf As an illustration, consider the theoretical lower bound for comparison-based sorting, as stated by Donald Knuth in The Art of Computer Programming: K × log₂(N). I developed a simple method that matches this limit. For example, to sort the list {2, 5, 7, 1, 4, 3, 8, 6}: Sort pairs: (2, 5) → [1] (1, 7) → [2] (3, 4) → [3] (6, 8) → [4] Merge… Re: Differential Directory, indexing method 2 Months Ago by xrjf "Just to clarify a previous mistake: the efficiency should be K × N × log₂(N), not K × log₂(N) as I initially wrote." Re: Differential Directory, indexing method 2 Months Ago by xrjf I've just made an update because some records weren't being added properly. The issue was that the form didn't take into account that the register field (in the call to DiDi) is passed by reference. Re: Differential Directory, indexing method 2 Months Ago by xrjf Just a quick update for anyone interested: I have revisited and significantly improved the code, aiming for a more professional structure and better performance. The updated version avoids freezing the UI during long operations and follows more robust programming practices. If you’d like to see DiDi in action, there is also a video … vb 12 Years Ago by tauseef300 vb project on buzzer Re: VB 17 Years Ago by Errods VB is Simple programming kind of a Legacy Unmanaged...........

VB has evolved to C# with somewhat different syntax. It is also called VB.NET instead of just VB, VB4-5-6 or VBA. So yield exists. [See here](https://msdn.microsoft.com/en-us/library/hh156729.aspx).
