So i made a new .net project with a gridview, Refresh Button, and Save button. The Gridview is filled by records where the Mobile Number for each record begins with "7" Theres about 7000 total that it brings back.
I want to loop through each Cell and add a "0" to the beginging of each of these mobile numbers, then user can hit save (user will only be me i guess!)
how can i change the text in the cell to do this? i thought this would be easy but for some reason i cant figure out how to change the cell values!
heres my code thus far:
Public Class FrmMain
Private Sub FrmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Im using vb2010 express. I have a datagridview in my form. All my cells in the datagridview has a "sunken" cellborder. When mouse is over a cell, i want to change the cell border of that cell to "raised". I tried lots of thing, but i havent suceeded to change just "one" cell's border.
My main goal is to have an excel spreadsheet that automatically plots the overall success of my stock portfolio over time (% change over time). I've been able to incorporate stock data into my spreadsheet by linking it to the web, but the trouble is the spreadsheet will keep no history of what the previous stock values were, so I can't graph how things change over time. This sounds like it might be too complicated to be built in to excel, so I was wondering if anyone knew how to program this in Visual Basic. Maybe something like this.... If refresh then new cell plus new time stamp. Another possibility would be to have a whole bunch of cells that refresh only once but at longer and longer intervals, e.g.,
I have a DataTable and want to connect the cells of one of its columns to cells in some other DataTables.
For example:
DataTable1.Rows(0).Item(2) is connected to DataTable2.Rows(4).Item(6) DataTable1.Rows(1).Item(2) is connected to DataTable4.Rows(2).Item(3) DataTable1.Rows(2).Item(2) is connected to DataTable3.Rows(11).Item(4) ...
I have a DataGridView with cells from a database file that contains data. Basically, I want to get the text from the selected cells in the DataGridView and display it in a textbox at the click of the button. The code for the button click event is:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim SelectedThings As String = DataGridView1.SelectedCells.ToString TextBox1.Text = SelectedThings End Sub
I'm trying to write an import function for getting data out of an excel file. How I currently do it is as follows:
Private Sub ReadExcel(ByVal childform As PhoneDiag.frmData, ByVal FileName As String)
Dim xlApp As Excel.Application Dim xlWorkBook As Excel.Workbook[code]....
From what I can gather, it more than likely comes down to this line:
Dim Obj = CType(therange.Cells(rCnt, cCnt), Excel.Range)
All I need is the text from the cells, not to create an object for each cell (and then not send them to garbage collection).Is there an easier way of just getting the text? Ideally, if I can get a method for getting the text values of the cell, I'd like to get the multiple rowArray()'s added to a master array and update the program's values later.
EDIT:I also realize that I have two options if I were to create a master array, say mArr, to hold all the data.Would it be better performance-wise to have mArr to be large and the sub arrays small, or mArr to be small and the sub arrays to hold more of the information?I ask because the files that will be imported will have more rows than columns, so I was wondering if there was any "set" way of doing it.
painting only part of text in cells like my column is NAME and values are bahushekh ,bahushekh1,msdn ,abc etc for that column. Now I want to paint only bahu in Red if it exists rest part will be black
All I would like to do concatinate text from two different cells using VB Express 2010. I know there is a =A1&" "&B1 Funtion if I were using excel an thier is also the concatinate function but I do not know how to use these in VB. Below is what I have so far for simply copying one cell to another.
title = CType(xlsApp.Sheets(Counter1), Excel.Worksheet).Range("A1")
i want insert a text into tablelayoutpanel cells..present i am inserting with the help of labels i am placing into cells..but it takes more time..so i decided to any other way to do this one.

I'm having trouble with an infragistics ultragrid using vb.net. I currently have a cell with the value "inner", however I want to be able to display a completely different string for that cell without losing the value. I understand that the cell has two properties, one value property and one text property. The text property is read-only so I cannot simply assign a new string to that.
I've got a button_click function that calls a Powershell script and outputs the results into a text box. This sometimes take a few seconds, so I wanted to first change the .text of the textbox (called Results) to "Please wait... searching remote PC" so the user knows the program is actually doing something.
Results.Text = "Please wait... searching remote PC" Results.Text = RunScript(LoadScript(fullPCinfoScript)) However, the text will not change. It basically waits to change the text of the text box
I'm using a richtextbox with scrolling and I need help with changing a certain line of text to an different color but when I use forecolor and appendtext it changes all the text in the textbox the same color. What can i do to change certain text lines?
Does anyone know why my text isn't changing? When my main form's "logging in" screen appears, the text is supposed to change as it makes changes to the main form. I did this by having a timer start when the form loads and as it ticks the actions are performed and the text changes. The timer's interval is 1,000.[code]By default, loadingtxt says "Logging In As (Username)". However, the text just remains as this instead of changing. Is the timer's interval not big enough or something?
I am using drawstring with the DrawMode set to OwnerDrawFixed on a tab control. The Tabs have a alignment set to left, but the text is displayed in a horizontal orientation. I would like to change the orientation to vertical. I am expecting this to be simple, but can not seem to find the correct input parameters for drawstring.
It's purpose is as follows:It basically is a "check list" for installed program's, and files. I image machines on a daily basis, and me making this application will save me hours, and hours of time.The basics:My program basically has 2 forms. 1st form, will be tabbed with "clients" or, different model of PC's. Each tab will have it's own checklist. I know how to pull external files already, though, that's not my issue.Basically, when I click "check list" button, it searches for an "adobe", and "Labtech" Directory. If it exists, it will throw the result into form2.richtextbox as Adobe is installed, or Adobe is not installed. Also, Checks if the second program directory is there, and then imports the info into form2.richtextbox on a seperate line. My question is, how do I change the color of the text per line?I.e. make Adobe is installed turn GREEN, and Adobe is not installed turn RED ect.
Form2.Show() Form2.Show() If Directory.Exists("C:\Program Files\ATI") Then
I'm fairly new to VB and I had a quick question. I have a multi-line text box that currently looks (line for line) like this:
scn <Name> Begin <Start Variable> End
What I am trying to do is make so when I enter text into a different text box (lets call it textbox2) and push an 'Update' button, it replaces a certain part of the original text box. For example:
If I enter "Dogs and Cats" into textbox2 and push update, then this:scn <Name>
becomes this:scn Dogs and Cats
How would you do that? Excuse my lack of VB programming lingo like I said I'm new to this language.

am writing a program in vb.net 2008 ... I want the user to be able to change the font on a different form, however any code that I try and write comes up with the error code property is read only.. I hope I have given sufficient detail... oh one more thing I am trying to use fontdialog from the tool box.
I am new to Visual Basic 2010, but I have been trying to make a line reader with an imported text document into a RichTextBox through an internet source.
I want the RichTextBox's line zero (the first line) to really be line one, but without changing the text in the TextBox to show the change. In other words, I want that change to happen in the background of the program.
I have tried... taking the text from one TextBox and putting it into another, while subtracting an integer value of onean attempt to use a timer to copy the text from one TextBox to another to read the line properly.
I have tried a couple of other things too, but most of them were much more complicated and I could not really explain what each thing did.[code]...
