I downloaded some sample code which includes a database query within the markup code. It makes a query to the database and displays the results of the web form and I would like to divert the output to a text file and I am not sure how to do this?Can this be done from here or would it just be easier to code it in the source and make a new connection to the database?
Sample code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringIP %>"
DeleteCommand="DELETE FROM [ip-to-country] WHERE [ID] = ?" InsertCommand="INSERT INTO [ip-to-country] ([ID], [BeginingIP], [EndingIP], [TwoCountryCode], [ThreeCountryCode], [CountryName]) VALUES (?, ?, ?, ?, ?, ?)"
Is there a way to write in the code to dynamically update the COM port if the USB/Serial adapter is plugged into a different port?
2nd: How do I have visual basic output the LAT/LONG coords that I have have show up in a form box to a text file every time it updates from the serial GPS?
I'm new to custom server controls and I'm hoping to use them to build various 'modules' for different sites I build to cut down on duplicate code.
I'm familiar with custom user controls in which I can create an .ascx & .ascx.vb file which can then be imported into an .aspx page and used freely.
However, with custom server controls I cannot find a way of using markup/html code. Is this possible at all or must all code be created programmatically?
I am writing an application that has to read and interpret data stored in some PDF files. The reading part is done but I am only able to get a dump of all the words on a page and not the format of the words. What I mean is that if I have to extract a table, I am getting the numbers in the table but not the markup which defines the table.Further, there is some formatting used which displays a few of these numbers within parentheses (meaning that those numbers are negative) but the parentheses themselves are not part of the text. Hence, I am not able to distinguish between positive and negative numbers present in the PDF table!
How do you get the PDF markup along with the text? Is a PDF similar in structure to an XML with tags used to markup tables etc.? If not, then, is there a resource which describes the salient features of the PDF DOM?I am using VBA and the Acrobat library (AcroExch etc.)
I modified some code to suit one of my other programs, but have come across a difficulty: For some reason, the output file is not outputting. I can tell all the calculations are being made (my computer is loud), but it's just not outputting.What should I look out for when modifying stanav's code that would cause the output file not to be outputted ?
What is the code to open a text file and append data to it, in visual basic express edition?Normally one would write:open "data.txt" for append as #1 but visual basic express does not accept it.
Is there an easy way in Visual Basic to record values to a CSV (comma separated value) file? I would also consider recording values to an xls or xlsx if it is easier. Anyone have any experience with this? Basically, during a loop, I'd like to take the values of 3 different variables and put them on one line of a csv, then make a new line in the csv and repeat with the next segment of the loop.
I want to output some of the data in my VB program to a .PRN file (no commas). I'd like to have the program create a header with the data, parameter info, etc... How does one begin something like this?
I currently have a system that saves student data to a text file. I can search for individual students and have their information output to screen. How can I make my system output every student in the text file to screen?
This question has been most likely been asked a number of times, but really hitting a brick wall regarding this.
The issue is that at the moment, I have to create a database using text files on VB.
So far I have managed to get the code working to add new customer and browse added records, but stuck on how to output/input back and fore to a text file, to store information, and after this input/output the text file to a DB ( Not worried about this at the moment)
Public Class Customer Dim CmrColl As New Collection 'Create the new collection. Think of this as an array of objects. Dim itemCount As Integer = 0 'A variable to help us scroll through the objects later.
I am having a perl script through which i achieve is split or output from text file for each single ID , the output text file will contain data of that ID and the anme of the file will be ID.txt so if i am having one main file containing 100 or 200 ID's and for each ID's may be 10000 or more lines i would like to have 100 or 200 files containing data for each single ID which i am able to achieve from perl but is it possible from vb.net
open(TH,"myfile.txt")|| die print "not open1"; open(THG,">error.txt")|| die print "not open2"; open(INFO,">myfileAll.txt")|| die print "not open3"; $gt='0'; $flag=0;
I have a data table that has thousands of entries. The table has employee production information: YearMonth, Employee ID, Pages worked and Jobtypes (e,k,o and r). I need to calculate a sum of each jobtype and a sum of pages worked for each jobtype, for each individual employee. I am pulling this data from an Access database and so unfortunately I am unable to use LINQ.[code]...
Every line starts with 56000 then the first key, the the second key and the rest of the line. I tried to use SORT, that's included with Windows. It does a pretty nice job, but i need to have my own function in case SORT is not available. The output should write 560001002001 at first.
I have a form that validates a users info, address, phone, etc. I want to have the form submit the data only if all of the fields are valid, but haven't had any luck. Right now the fields are able to validate but the form submits the data to the text file regardless of whether the fields are valid or invalid.
Here is my code Imports System.Text.RegularExpressions Imports System.IO Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub [Code] .....
How to create an if then statement to only submit the form when the data is valid. I was thinking I might have to set up a separate function but I'm not sure how to set it up really.
I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.
I am looking to create a VB 2008 Express programme which converts a data stream from a picoscope muscle sensor into a power output board which controls a mechanism.In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.
So 0.8 V > = send text file (0O=100%) 0.2 V < = send text file (0O=0%)
so when muscles being senced move the device turns on and off.I think I am successfully getting the data stream from the Picoscope which is plugged in the usb. I am using codes and examples that the programming guide for the device provided.here is a quick snap shot of the code (ps2000 is the driver used for the device)
how to get the data to be displayed or how to tell the programme to do something with the data.The device also came with an example of how it can record data to an excel sheet if anyone needs the code to gain a better understanding.
I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1 Dim selectednames As String = "" Dim index As Short = 0 Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1 Debug.Print("namesarray(" & x & ") = " & namesarray(x)) Next

I work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.
i was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?
Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"
I save data from datagridview to text file. I also load the same data from text file into datagridview for edit and update the same thing to text file. Let say this text file i called as Drill.txt. I have another text file called header.txt which need to match its value with the value of Drill.txt file then overwrite value from Drill.txt to header.txt. Now i want to make my Drill.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program
