Setting A Radio Button Value According To String Returned From Database. String Is 'Yes' Or 'No'
Jul 24, 2009
I have a radio button control on a web form. The members of my ListItem collection are
assigned the following.
Text No
Value 0
Text Yes
Value 1
So what I need to do, is to readd a varchar value from my database and if the column value returned equals 'Yes' then I need to select the radio button that has the assigned value of 1. Otherwise if the value read from the database is 'No', then I need to select the radio button assigned a value of 0
So how can I set the value for my radio button? I experimented and could not figure it out. The 'Yes' or 'No' value is stored in my database in the field ds.Tables("employee").Rows(0).Item("answer")
So I tried something like this which is not correct:
I am using VB.NET and I can't compare the radio button lists selectedItem.Value to a string, it doesn't work...here is the code: (I have also tried selectedValue it does not work either)
[Code]...
Why won't it evaluate that rblOne.SelectedItem.Value = "No" !?!?!? I tried rblOne.SelectedValue, that doesn't work, AND I added .ToString to both, which did not help, I even tried it w/ "No".ToString...this doesn't make any sense.
why the button in "String Collection Editor" is disabled (Please see the graph)?My final target is to enter a name-value dictionary in App.Config file, is there any alternative method to do that?
My program needs to convert the variables users enter in textboxes from metric to imperial and vice versa so the user can switch units at any time during run time and have the values in the textboxes display the correct value. The problem is that for example if the user initially enters all his values in metric when converting I will be displaying the rounded value of the imperial value. If the user initially enters his values in imperial, when converting I will be displaying the rounded value of the metric value.
But the problem occurs when then user switches back to the original units all the values go to 0 because in the coding for my radio button I set the txtboxes to the rounded xxx value. How to code the radiobuttons to detect what unit was initially selected to set the right values. What I tried doing was set a counter on the radio buttons to determine which one has been pressed more often... but there has got to be a better way to do this..

In my webservice I have converted the ado recordset to xml and returned a string.In my application I managed to convert it back to the ado recordset but now I need to convert that recordset to dao as I need to use some of the functions provided by dao that ado does not have.
I'm trying to establish a connection to my SqlDatabase while getting the connection string from a function. This will eventually lead to dealing with the appconfig file, but for now I'm just getting the basics established.

I have been having some problems trying to decrypt the string returned back from SagePay.I used their asp.net kit which included the encrypt and decrypt functions using base64 - sending the information to SagePay is not a problem but I am having a number of problems trying to descrypt the string.Here is the function I am using to descypt:
Private Function base64Decode(ByVal strEncoded As String) As String Dim iRealLength As Integer Dim strReturn As String Dim iBy4 As Integer
[code]....
I don't think the web server is trying to encode anything as there are no + symbols within the url string and I have just glanced over the two to compair they are the same.This returns a blank string whereas when I use the sections commented out in the first loop i get a really weired string back and when I use their simpleXor function it just returns complete nonsense.
i have a form in vb.net and it has two groups of radio buttons and once a selection is made i need to update it and save it into the database(ms access). i am failing to get the information to save into the access database but instead i am getting an error on the command execute query. here is my code:
there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.
i have problem that i know once someone answers, i will kick myself, but here goes. i need to move the text next to the radio button to the left of the radio button, that part is easy just make sure the the "right to left" is maked yes, got it. but, the problem is i am making a seating chart and the seats are labeled 10-a, 10-b etc.... when the right to left is set to yes my text reverses and becomes a-10 and i can't seem to figure out what is set in the properties the is causing the alpha to be placed before the numeric.
Ive created a sql database using visual studio 2010.I need to use a radio button on my form, which when checked, updates a table for the record it is currently on with the integer 1.This is as far as I have got:
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged If RadioButton1.Checked = True Then End If End Sub
i have 31 PAIRS of radio buttons Yes or No in a web form which will insert the value of radion buttons or text of radio buttons in a single table of 31 columns in SQL server. I grouped each pair of radio button (Y and N). How can I retrieve the selected radio button value of the group and insert it into MS sql server database table using one insert command in VB.Net?
I got an app, which receives data via a R232 port, convert it to a string and on the other side I got a database, where the strings are saved. How can I find a way to compare the string with all strings in one database column and get back the another stringform the same row in this database. I never programmed a database
Visual Basic 2008. Here is the code. I have a form where there is an exercise as follows: Dim varText as String = " Elephant, Cow, Snake, Horse " The question ask how many letters are in the word "Horse". The possible answer are 6 radio buttons with values of 3, 4, 5, 6, 7, 8. What I need is how do I check that the correct radio button is selected.

The problem I have is that many times, the dataset that this control is bound to is empty. Therefore, the user continuously gets an error saying that one or more fields is missing. When I debug the code, I can see the code in the class loop through all of the radio button controls on the form. Since none of them match the field from the database, the code throws the error. I assume the code expects a match.
Should I modify the class to handle the case when there is a DBNull value? If so, what would be the best method? Or should I approach this situation in a completely different manner?

trying to write a simple form for calculating professor's salaries depending on their degree and position.my problem is that the when i select a check box, the value is not being updated until i select a different radio button. it probably doesn't make much sense here,
Public Class frmMain Private Sub optLecturer_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optLecturer.CheckedChanged[code]....
the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:
With setting the string length. I have got a streamreader reading from a .doc file into a listbox and then i want to set the string length of how long it to be and then if longer to go to the next line so it will fit in the listbox as the listbox you cant scroll accross but you can up and down.
Ive done this so far:

I originally wrote this with Option Strict Off but I'm wanting to rewrite my application with Strict set to On. The error I get with Strict set to on is: "Option Strict On disallows implicit conversions from 'Object' to 'System.Delegate'."

I have 26 buttons, each corresponding to the letter of the alphabet from A thru Z. I have a method that I've created that accepts a button as a parameter and sets the case to UPPER case if the text of the button is lower case or lower case if the text of the button is UPPER case. My method looks as follows:
Private Sub ChangeLetterCase(ByRef MyButton As Button) If _upperCase Then MyButton.Text = Chr(Asc(MyButton.Text) + 26)
I did this before but I completely forgot how I did it... I have a website that has a 'div id', I want to get that text and put it in my textbox on my app.
I think it was something simpe like the following; TextBox1.Text = WebBrowser1.Document.GetElementById("IDname").GetAttribute("value") = TextBox1.Text
I've been pulling my hair out over some unexpected behavior from nullable integers.If I set an Integer to Nothing, it becomes Nothing as expected. If I set an Integer? to a String that is Nothing, it becomes 0! Of course I get this whether I explicitly cast the String to Integer? or not.[code] Previously I had my code up here so without the explicit conversion to Integer? and everyone seemed to be fixated on/confused by that. There were a lot of suggestions that Option Strict On would catch this type of thing. However, this is actually a quirk of the string-to-integer conversion rules which predate nullable types, but still impact them.
How you set data type to string? I am using this source: Dim Resp As String = AxInet1.OpenURL("[URL]", vbNullString) TextBox1.Text = Resp I need to replace the vbnullstring. On other forums, people are saying to use icstring but still i am getting an error that it is not declared and I added reference to imports system.text.

I'm creating a file thats need to be in this format url... I need to be able to set the limit of the string length for certain fields.Is there an easy way to set the limit of the field so that if the string was larger then the limit then just take the substring and if smaller would add extra spaces?I was able to accomplish something similar to this with integers by just using .toString("00000").
