Modifying Text Data Based On Start Of Lines?
Apr 19, 2012
I am new to programming, so I am looking for somewhere to start with this project.What My project needs to do, is that the user inserts data consisting of multiple lines (up to thousands of lines) Into a text box of any type.When a button is clicked on it goes through the lines and alters lines based on what it starts with.
[Code]...
Clicking the button would cause every line with DDE at the beginning to be deleted, while leaving everything else intact.I'm not just looking for handouts, I do want to learn. I just to know what to look at to do this.

I know it may be quite easily for you. i have a text which contains 40 lines, I want to remove lines which starts with a constant text. check below data.
When I used (?mn)[+CMGL:].*($) it removes the whole text , when I use (?mn)[+CMGL:].*(
) , it only leaves the first line.
+CMGL: 0,1,,159

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?

Modifying data with the ListView's EditItemTemplate by programmatically settings its DataSource property and calling its DataBind method. I don't have option to use data source control for ListView. All ListViews are bound with data from code-behind. So, I have to handle the Edit/Update mode of ListView manually. [Code]

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I am populating data form database in combobox. This data is in the form of numeric codes like 112, 113,
The thing i want to do is on selecting some code like 113 from combobox, it will display it as ABC113 in the combobox.if code like 114 selected from combobox, it will display it as ABC114 in the combobox.
I don't want to store this modified string in database.
Please help me to achieve this.
Provide me some sample code or link for simple combobox or combobox in datagrid.
i think there is no change in code in both above cases.

This task is a little out of my reach so i dont even really know where to start...I want a user to click the command field "select" in my gridview. I then want them to be redirected ( response.redirect()) to an input form that will have its various asp.net text boxes filled with data from that selected item. I also need the ability to do this logical process:
IF the form is loaded from user
selecting item in gridview THEN
''Populate controls with data from selected gridview item Else Load

I have the following code that replaces an item in a richtextbox with a new one. Reg-replace works fine but only when the pattern matches only one value. When there are two similar values in the richtextbox it matches them both. How can I replace based on specific lines?

I have a dataset bound to a DGV thus:
Me.BudgetTypesTableAdapter.Fill(Me.RestelDataSet.BudgetTypes)
When I save new data I use :
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Me.Validate()
[Code].....
should work as the Rowstate is checked to see what should happen ie (UPDATE, MODIFY OR DELETE).

I am making a game of tic tac toe, and I have 9 buttons lined up in a grid pattern. I want to select a random button for the computer to start the game from.
I have an array set up with all the names of my buttons, and I was thinking of picking a random entry from that array to start working from. This I have done fine, but I cannot change the text of a button. My code:
''# Define the array
random(0) = "tl"
random(1) = "tc"
random(2) = "tr"
[Code]....
as you can see, I can't simply do StartPoint.Text = "O", even thought StartPoint holds the name for the button.

1. The application's text box controls are entered manually in my.settings (e.g., tb1, tb2, tb3)
2. The application user "adds" a row of text boxes, which are iteratively assigned a name to match the above my.settings names
3. Upon "save" by user, the text in each text box is associated with its control (e.g., If cntl.Name = "tb1" then My.Settings.tb1 = cntl.Text)
4. The User needs to delete one or more rows previously added
Question:Under #4 of above, what is the best way to delete the rows and how can I use the app.config file to update the above data so I can reuse the named text boxes and keep everything sequential?

I have this VB.Net 1.1 project that I have to make some changes to. There is a flag in the App.config file. If it is false, the page just loads a splash screen and runs the program normally. If it is true it first opens a login window. VB.Net is not something I've ever worked with before. I can't for the life of me figure out where the logic for the picking the startup object is. In the property pages, Main.vb is always set as the startup object, but that's not even the window that loads up when the flag is false, it always comes after the splash screen.

My first post! im quite new to programming but loving every minute of it.Basically i want to open another exe file from vb.net 2010. i can do it normally using
system.Diagnostics.Process.Start _ ("c:winamp.exe") if winamp for example is installed on another pc in another location i want to run it from my program but i want there to be sort of like a settings.txt file where you can edit the path to winamp and my program should first read the path set in the settings file and then open accordingly. how do i go about doing this?
btw it would be great if you could point me in the right direction for making a windows form where one can edit the settings file within my program without editing the settings file in notepad

i want to create a html editor. to get started, i want the app to be able to find certain words, and change the font/color/size/etc. as for <a href=""><b> and so on, without changing the rest of the text after the selected text was modified. i'm sure that it has something to do with RichTextBox1_TextChanged for text that is being typed and just a button click for modifying selected text.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

I am using the Process.Start function to open a program based off a registry value. It works, sort of. Here is the snip of the
Imports System.Data.SqlClient
Imports System.Console
Imports System.Configuration
[Code]....
The program opens with the correct registry value, but the program itself does not run quite right. This program feeds into Intergraph and brings up the selected drawing, but there is a feature of intergraph that doesn't work. If I manually start ( double click ) pdsicon.exe the program works just fine. It only when I call the process that it doesn't work quite right.
