How To Limit Results Of ComboBox

May 28, 2011

I have a simple database comprised of one table (called "Plants") and one form (called "Plants To Use"). In the "Plant To Use" form there are two fields: Plant ID (a nine-digit ID) and Paired Plant ID (a combo box pulling all of the Plant IDs). I want to limit the Plant IDs in the combo box to only IDs that match the 3rd, 4th and 5th digits of the "Plant ID" on the form. For example, if I pull up the record of 99874234 on the "Plant To Use" form I want my combo box to list all other Plant IDs that have 874 in the 3rd, 4th and 5th digit (e.g., 778746320, etc.).

Datatable Rows - Populate A Combobox With All The Results Where A Condition Is Met

May 5, 2012

I've populated my DataTable will all the results from a SQL search. Upon a button click I want to populate a combobox with all the results where a condition is met. My DataTable as a column called UserID and I want to add all results where the UserID is equal to a set value (for example 12). I can do this to add all results and I guess I could add a if statement inside this to be If Entry.Tag = 12 Then but is there a better way?

May 28, 2010

I'm trying to create a Windows form application which uses a few data grid views to pull data back from a SQL Server database. I've managed to get the data back okay from the tables but what I want to do is filter that data dynamically based on values input by the user from a combo box and a date time picker. Each of the data grids display production data for a machine but the combo box and date time picker will allow the data to be filtered by shift and date respectively - how to I pass the values of these to the SQL query returning the data?

How To Prevent .net Combobox From Displaying Multiple Results From A Single Data

Dec 9, 2010

I am currently having a headache on how to solve this problem that i am facing.here is the situation:I have a combobox and a list box on the main form. The combobox will get the data from the ms access database.In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987

So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown.

Show The Final Results Instead Of The Results Real-time

Sep 28, 2010

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

Calculating Value And Showing Answer In Label?

Jan 24, 2012

I have several buttons in my form and they each need to add, subtract, divide and multiply certain values together but I seem to be having problems with this. I didn't expect anything to go wrong and its probably a rookie mistake, but take my first calculation for example; a user must enter a value in a textbox (txtDays) and and also when one of my various radio buttons are pressed a value shows in a label (lblDailyHireCharge). I now need a way of multiplying these values to give me my answer shown in a label. I have done this by adding a button when which pressed multiplies the txtDays value with the lblDailyHireCharge and then shows it in the label, however it keeps on showing "0" when i click it.

Below is my code, I am basically saying that the value of both of those figures is intDuration and that lblDuration is where I want it to go when the button is clicked.
Private Sub btnDuration_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDuration.Click
Dim intdays As Integer
Dim intDailyHireCharge As Integer
Dim intDuration As Integer

Concatenate A Equation And Answer To Text Box?

Mar 22, 2011

In our school theres a programming class and the teachers gone for the week and the sub is starting to get very frustrated, so I offered to help in any way i can. I have never programmed Visual Basic but I have programmed Ms-Dos, Javascript, HTML, *.vbs, *.ahk, *.gml, and a variety of other languages.

The class is going to build a program that calculate how many rabbits are born in a family. So when they click the button it shows in a text box the actual equation and then the answer after the equal sign that where i assume concatenation comes in.Here's the code I've thrown together for when the buttons pressed:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim RabitAmount As Integer
Dim ShowEquation As String

[code]....

I got the equation to answer it self and show in the text box but it won't show the equation?

Now in the database some of the answers are very short, one or two words, but some can very lengthy. So, my answers seem to disappear if lengthy (argh), I cannot make them shorter. How do I squeeze the answer in the Radio button? Can I add what.I do not want to change from radio button to something due to the extreme low knowledge of VB08.

NumberDecimalSeparator Is Giving The Wrong Answer?

Oct 16, 2009

I've got this code to get the decimal and groupseparator settings on a computer:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim NumFormat As New System.Globalization.NumberFormatInfo

[Code]....

The problem is that on my computer NumberDecimalSeparator should return "," and NumberGroupSeparator should return ".", but it's just the other way around when I try to get both separators from my system. What could be going wrong, and even more important, how to get the right strings? I did check my locale setting to make sure I'm not crazy and I also didn't switch the textboxes.

Quiz Program - Asking Five Questions With Yes Or No Answer

Mar 19, 2009

I'm trying to make a quiz application with Visual Basic at the moment. I want to write a routine that asks five questions to which the answer must be either Yes or No. It must add up the number of Nos and if the number of Ns is less than two then print out "pessimist", otherwise print out "optimist". So far this is the design of what I've done. [URL]. However, I have no code which I've produced on my own.

Code:
Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class

I really don't know how I can kind of add up all the results from each individual question, seeing as radio buttons are used.
