Ensure Textbox All Fields Populated With Text And / Or Numbers
Apr 17, 2010
I have a form (formA) which contains a tabcontrol with two tab pages. Each tabpage has 6 textboxes and 3 comboboxes. In addition to the tabcontrol there is a separate combobox and textbox. The question I have, is how to best ensure that all these fields are populated with text and or numbers? From this a start button is pressed which generates another form (formB) which requires the fields from (formA). If for instance 1 or more fields is not populated, then generate a message to show the user which 'box' requires data. Only when all fields are populated will this enable the 'start' button.

I am running Visual Basic Express 2008. I realize this forum category is for VB6 or earlier, so please kindly inform me of where to post this if this is incorrect.This is actually the first forum I have joined ever because I can't figure it out on my own and can't find the code off the website. I am almost done, i I have a ComboBox and 4 text boxes. At the bottom it has CLEAR, UNDO CLEAR, COPY ALL TO CLIPBOARD & COPY SOLUTION which does so for the ComboBox and all 4 text boxes. The format like this (CORP is the ComboBox):
CORP - Workstation - Won't power on - HOSTNAME/USERNAME
PROBLEM/REQUEST:
started happening today
[code]....
And then due to the ticket entry system we use, I have a separate COPY SOLUTION button and that works just fine, but that would read as:
Dispatching tech
Now here's where I'm caught up on, I need to take a textbox where I don't use it because I don't have a use for it dependent on the issue of the person I'm working with and it'll look like this:
CORP - Windows - Password Reset - USERNAME
But, this is where I'm getting stuck, it keeps putting stuff like:
CORP - Windows - Password Reset - /USERNAME
or
- Windows - Password Reset - /USERNAME
[code]....

I have an Access database file, which the application needs to connect only when it needs to run a query. The database has five fields. The first two fields contain numerical values (double). The rest are text values.
Well, I don't have trouble accessing the database file. In fact, I don't have trouble running a query on those three fields containing text values, either. But I have trouble making a query on numerical fields. If I run the following, the application will exhibit a data mismatch error.
'MyConnection As OleDbConnection
'MyAdapter1 As OleDb.OleDbDataAdapter
'nIP is a large number like 3647665152

I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems.

So this is my code
Private Sub SK_btn_OpenFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SK_btn_OpenFile.Click
Dim sLine As String = String.Empty
Dim sAllTExt As String = String.Empty
If SK_OpenFileDialog1.ShowDialog() = DialogResult.OK Then
[Code] .....
The text that appears in my textbox is this
Person 1 * 12 * 123.45 *
Person 2 * 24 * 2345.78 *
Employee 1 * 34 * 23.34 *
Employee 2 * 123 * 11.23 *
I want to take the average of the 2nd field. Each field is separated by "*". I have to use the format display 2 integer digits and 2 decimal digits.
So in this case
12, 24, 34, 123 are the numbers
I have to do the same thing for the 3rd field. But I got to add all 3 numbers instead. and use format to display five integer digits (with leading zeros), and 2 decimal digits.

I'm trying to create a form application in which the user is prompted to enter a date in a textbox by clicking on a button next to it that would popup a calendar. Then the user would select a date from the calendar and the textbox would be automatically populated with the date selection. The user could also just type it in, but I would like to have some kind of validation before accepting the date. I will be converting the date to an integer in this format YYYYMMDD to pass it to a query on a SQL Server 2005 database. Don't ask me why they're storing dates as integers I have no idea I'm just working with what I have hehehee. I've been looking online and trying different things but haven't been able to figure this thing out.

I can get them to popup with a textbox where I have enabled="false" so that it can't be edited, but it shows all the tags along with the text such as the <p>, <li>, etc. Is there a different control I can use inside of my modal that will show my text better?

I've been ttrying to code an app that will act like the VB intellisense, without the added properties. In short, when I type (in a multiline RichTextBox), the letter t I would like the populated listbox show at that point (because "Then" is a word in the listbox) and if I click "Then" in the listbox have it "autocomplete" the word and display it in the color blue.
lstKeyWords.Location = rtb1.GetPositionFromCharIndex(rtb1.Selectionstart + 10)
lstKeyWords is the ListBox and rtb1 is the RichTextBox - This was the only way I could get the ListBox to show in the "almost" correct position?

When the program is run on a Vista or Windows 7 machine, the text in the messagebox is eschew and the formatting looks sloppy.Is there a way in Visual Studio to ensure the formatting of text in Messageboxes is consistant between XP and Vista/Win 7?

I have an Asp web form (language is VB) that is used to update records in a SQL database. The form is populated with the record with many textboxes as well as dropdownlists. I have a textbox that is populated with a date from the record and is displayed with the date and the time. I would like change the format to only display the date as "mm-dd-yyy". In the code behind the date field is called from the database and put into the textbox via:
"MyDate.Text = dt.Rows(0)("MyDate").ToString()".

I'm trying to get a combobox to be automatically filled from a text file and have it editable by the user.
So far, when the program is running I can add new items and they appear in the text file and combobox but when I restart the program the combobox list is empty even though the text file has stuff in it.
Dim w As New IO.StreamWriter("z:url.list.txt")
Dim linecounter As Integer
For linecounter = 0 To ComboBox1.Items.Count - 1

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

[code] Mary, Murphy, 16, 893782, Douglas etc.From here the user selects the person they wish to see displayed in the datagrid with all all other relevant details from the text file displaying. Problem is I cannot figure out how to refer to the selected person and then get it displaying on its own in the datagrid. [code]

I have a list view populated by a database. The columns for each record are First, Last and EMPID. When I look at the list view on the form at runtime, I can see some/all of the First name and then below that may be part of the Last and some ... periods and no EMPID. When I hover over the record, I can see the EMPID. Is there a way to have all of the information in the record visible in the list view?

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

Language: vb.net
File size: 1GB, and stuff.
Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).
Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.
Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.
I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.
