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?
View 3 RepliesIs it possible to write code to record the pc screen and output a video file of it?
View 3 RepliesHow you record a screen and then output the recorded frames in a .avi file or .wmv, doesn't really matter what kind of file.
View 1 RepliesIf I want the my output to be written to a text file do I just need to add:
Respone.clear() , Respone.ContentType = "text", Response.OutputStream.Write(bytes, 0, bytes.length) , Respone.flush()

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

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";

View 2 RepliesI 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 am pulling this data from an Access database and so unfortunately I am unable to use LINQ.[code]...
View 4 RepliesI 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 (?, ?, ?, ?, ?, ?)"

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

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'm using Vb .net 2008
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'm trying to read a text file with multiple lines and then display it in a textbox. The problem is that my program only reads one line.

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)
ps2000_open_unit()
ps2000_set_channel(ps2000_handle, 0, 0, 0, 1)
ps2000_run_streaming(ps2000_handle, 250, 1000, 0)[code].....
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 know this script [below] gives the pc motherboard number ,...well I would like to know how to write the result number as plain text somewhere in the windows, in a folder, or registry , or in a harddisk volume,... I know I could use

I am using IHTMLElementrender.DrawToDC but when sending to a screen DC, the image is cropped by about 10%. The image is large enough and I can draw using VB Line, Print or API etc, to the area that is cropped, so it isn't the DC at fault.On any printer device it works exactly as expected. I believe this is a bug, but where can I go to report it?

View 8 RepliesOkay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?

I'm trying to create a small program, which I think will be helpful to others(in here). My aim is to convert the English text shown in screen to Malayalam. English-to-Malayalam conversion is not a problem. But the problem is, how to extract the text from the screen. In most of the converter/translator, the text needs to be copied or written down in the translator tool. But my program will cut off that part. That is, simply move the program window (having a rectangle hollow portion) to the English word that needs to be converted. And upon pressing a button (or autodetect), the English word is converted to Malayalam.
So, my question is how to extract the English text(or words) from the screen (which is seen through the hollow portion of the window.
Here's a screenshot of what I'm trying to do.
