How can I produce a total for values in a datagrid and them display them in a label?
I have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read)
Dim rd As New BinaryReader(fs)
Dim convertDB As UInt16
For i = 0 To rd.BaseStream.Length

I'm new to VB.net and have only a few projects under my belt. This one has me stumped!! I need to open a file and search its contents hex byte by byte. (Similar to Hex editor). On finding a particular value I need to replace it with a set hex value then write and close the file. So far I have only managed to read / write the ascii equivilant.
View 4 RepliesI finished a course on VB in school. Now, I know how to read in a file, but I'm only used to plain text files. The file type I wish to use is called .pkm. It is a pokemon file type (yes, pokemon, don't make judge). Anyways, it's basically a file full of hex values that the game reads to display a pokemon. A friend of mine made a program that displays the hex from this file. He used Delphi so I'm not really sure about it in VB.
View 5 RepliesI am trying to read data with a test routine from a fairly simple 3rd party Excel file. The file has three sheets and was created by Open Office 3.x as an 'Excel 97/2000/XP .xls' file. The later, still to be programmed, application must later run on machines with Windows XP Professional using the 2.0 .net framework and no Office package installed. The content of the file does not need to be modified by the later application. For some reason, numeric values are not read correctly. They "convert" to DBNull. I've searched around a bit but not found a 'simple' solution for solving this problem. Adding 'IMEX=1' or 'HDR=Yes;IMEX=1' to the connection string results in an error 'Installierbares ISAM nicht gefunden' (installable ISAM not found).
Based on various examples I've found, I've written the following test code:
Option Strict On
Option Explicit On

I am working on a project which I want to share with some people, but since I wont give away my source, I want them to be able to customize the values (By values, I mean like if I have a button that says Donate, just an example, then I want the application to read the link from a .xml file, or an .ini file, so people can edit it)
I dont know if that IS Values, but it sounds like it to me.
Here is my Donate Button code (STILL JUST AN EXAMPLE)
Private Sub Button5_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click

I'm using VB.Net's Excel component to read Excel file, but the performance is totally slow, since it has to loop through cells to get values. Reading a file containing one sheet with 1162 rows and 105 columns (which is small size compared to my general requirement) already costs more than 5 minutes.1. I want to ask if any of you have suggestion on reading such an Excel file with better performance, except OleDB, cuz most compies here have vesion problem?2. Is it normal that it tooks a long time for Excel component to read Excel file, or is it that I implement the code in a wrong way?
View 7 RepliesAdded for my quick reference.When you use the following code to retrieve the values from config file in a library project.
Value = Configuration.ConfigurationManager.AppSettings("KeyName")
The application will look for this key in AppSettings section of calling assembly and may lead to unpredictable results.

How would I go about reading a textfile, finding values and using the values in the program?Now I want the program to read the text file, find [1], use the first line after [1] as value for a variable, and the second line as value for another variable. After that I will run some code with the values and then do the same thing again for [2] etc.

View 9 RepliesI read a csv file into my .net program using ado.net and display it in a datagridview.In the file I have two rows. The first column is a component id, and it is supposed to be numeric. But the user can edit the csv file before having my program load it, and accidentally put text there. That is something I want to edit when he presses a button to add the data to the database. So let's say he puts a value of A in the first record and a value of 1 in the second record. Or vice versa. What is displayed in the dgv is a blank in the first record and a 1 in the second, or 1 in first and blank in second. If both csv records are A, then what is displayed in the dgv is an A in both the first and second records. I don't understand what is happening. The fact that there sometimes is a numeric in the column makes it think it is a numeric field and therefore only display numerics and blank otherwise, and the fact that there's always text in the column makes the code know it is a text field?
View 2 RepliesIve figured out how to open a file to read and then display it, and i can probably work out how to write a string to a file. The part i am stumped by is this. Say i open a text file with the following text I has a badger i then want to correct this to I have a badger.
Its just an example and not for a grammar corection program. What i want to do is detect what was said and alter it acordingly. I presume this would come under string manipulation but i cant find any details on this.
How do you read a CSV file and display the results in a grid in Visual Basic 2010? This sounds so simple but I still can't find the answer to it after googling for a while. I have DataGridView on a form and it's called DataGridView1. I have a csv with just 3 columsn of data and I want to be able to display them.

View 2 RepliesI have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.
