I need to display (read-only, I don't want the user to be able to modify the data) a set number of log entries. I figured using the data grid view would be the best solution. Basically the data is an error log that contains 3 fields (columns)
ID (a number from 1-20), Flag (number from 0-255), and a Description (string). I don't want the data linked to any database or anything.
These events occur asynchronously so I need to be able to add events (rows) to the data grid as they occur.
I also need the ability to clear all events (rows).
I guess the first question is if the data grid view is the best control in VB to use.
Is there a good example on using the data grid on how to add data to the data grid view one row at a time?
I just want to display data in a DataGridView (from SQL - already made the connection) based on what is selected in a ComboBox (data that is also coming from SQL). The 2 are separete on the form. I am using VB 2010.
This doesn't work for me:
objCommand2.CommandText = "SELECT ProductID, Name, Color, Size, ListPrice FROM SalesLT.Product WHERE ProductCategoryID = " & cbCategory.SelectedValue

I have an Access table that contains "Customer Number".
I have an ODBC dataset (iSeries IBM Client Access, or AS/400 data) with a customer table in it. I want to link the customer numbers in the access table to the ODBC table so I can show the customer number from the access table and the customer name, city, and state from the ODBC table.
I want to display this information in a grid. I also want to be able to add records to the grid (which adds them to the access table). What is the best way to get started doing this? I am using VB2005. I could use MS Access and have it done in about 2 minutes, but I want to take the plunge and learn VB2005.
But this VB2005 and .net thing seems like they re-wrote the book on programming and I cant seem to get a grasp on it. I have tried several projects like this in hopes of learning, but ended up abandoning them in frustration.
I have an excel file that I would like to load into my form and display there.

View 4 RepliesI am using a data grid view to display information from a database and I can't get it to update correctly.I can see the data from the database but when I change information and save it it changes the entire column's information. My rows need to have different values in the same column so this is a problem.Here is my code so far, what the program does is makes a list of transactions that are entered.

View 1 RepliesHow do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

I need to know how to display the result of a select query in a datagrid or GridView with VB.NET?
Consider SELECT * FROM some_table. I don't know what columns the table has. Is there a way to just output the result to a table, with a dataset for example?
I'm using an array to populate a datagrid. I want a password protected button to be able to clear the data from the grid. I thought this would be fairly easy but so far it's not working. The following code doesn't generate any errors but the array still has data in it.
If txtPassword.Text = "bucswin" Then
Array.Clear(DataGridValues, 6, 23)

Rule 1: Replace all of the vowels (A, E, I, O or U) in the original password with a number as follows: (20 points) Replace the first vowel with the number of 1. Replace the second vowel with the number of 2. Replace all other vowels with the number of 9.
Rule 2: Replace all of the numbers in the original password with the letter Z. (15 points)
Rule 3: Reverse all of the characters in the original password. (10 points)
Rule 4: The enter password should be non case-sensitive. All the letters in new password should be in upper-case. (5 points)
This is what is should look like:
My code:
CODE:
Right now I'm not worried about the efficiency of the code (i.e. simplifying code into fewer lines). The problem I am having is the locating and replacing of the vowels. When running the program the code will replace all of the numbers with "Z", reverse the string, and make all letters uppercase. When it comes to locating the vowels, the program squares the number it goes through the string by the number of letters that it contains. I don't know why it does this.
when the string contains more then 1 vowel the first time it goes through it replaces all vowels with 1, then goes through again and replaces all vowels with 2, and goes through again repalcing all vowels with 9. These are all then combined into one string.
The research I have done has only turned up how to replace vowels with one thing (i.e. all vowels become "*")
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.

I'm making a console app that uses your name and then asks for a password and displays the text. So the start is like this
18:36:01 [Info] Program is started.
18:36:01 [Info] Please enter your name.
NAME GOES HERE AND THEN ENTER TO PROCEED
18:36:04 [Info] Hello Xoslize, Please enter the password.
Password Goes Here and then Enter to Proceed
Some Text Goes Here
How do I do that? I mean the enter to type text, etc. Btw, how about using color on every word?
I need to display an two-column editable grid not bound to a database. I took a look at ListView with Mode=Details, but it appears that only cells in the first column can be edited. I then took a look at DataGridView, and am having two issues:
1. When editing a cell, it adds a new row: [url] How can I prevent this?
2. I don't like the grey background and would like the grid to fill the whole space, right and below.
BTW, if you know of a good tutorial on using the DataGridView unbound, I'm interested. [Code]
I am writing a program to be able to input a password and take that password and display a new password in a label. the new password will display the results as follows. Any vowels in the old password will be displayed as an x in the new password and numbers will be displayed as x's, and the last part it will display in reverse order so if I enter in timmy1 it should display zxmmxt. I do not know how to write the code to be able to reverse the string to be able to display the password backwards.

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!

I have been staring at a blank screen for over an hour trying to figure out the best way to build this app. We have a warehouse with consumables. These consumables are stored on racks that are three rows high and 15 columns long. I need to display the contents of these racks with the following; Item nameUnit quantityUnit expiration date
Now while this in itself would be a simple thing, I need to . Take a look at this image, the lower portion of the image shows basically what I want to display as far as the form goes. Instead of the "Row 1-1-1" text, I want to show the item, qty and exp. There are multiple rows. It should also be noted that each location may have more than one item stored in it, and there might not be anything stored in it. So I guess my question is, from a design point, is it better to create a small table for each location and then join those tables to a main "Row" table since there will only be a single row displayed on the form at a time? How would it be possible to keep the data properly ordered from a coding perspective? How can I ensure that each storage location remains static unless the item is moved?

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.
