.net - Unable To Select More Than 1 Radio Button?

Feb 24, 2011

I have 4 radio buttons, r1, r2, r3, r4. These four radio buttons are in a group box.

r1 and r2 for asking the gender of person.

r1 for Male , r2 for Female

r3 and r4 for asking whether the user would like to continue.

r3 for Yes , r4 for No.

When I click r1 , r3 becomes unchecked and vice versa. Similar is the case with r2 , r4. So at a time I can check only one radio button. How can I get around this problem . The groupbox is essential so I cannot remove it.

How To Cause Webbrowser To Select A Radio Button

Dec 3, 2011

I am trying to make a utility for my personal use.  I want it to log into a website and fill out a form for me.  So far, I can get it to fill in the input boxes and select the right options from the comboboxes.  

I am having a problem with the radio buttons on the form.  

Here is how I use webbrowser to select MICHIGAN from the list of states.  This works fine, and I present it as an example of what I am trying to do:

WebBrowser1.Document.GetElementById("idccafhState").SetAttribute("value", "MI")

I am trying to find something that will do the same thing, but with a radio button.  So far, nothing I do will work.  There are two radio buttons. One basically says: "Yes, I would like this item - add it to my shopping cart." The other says: "I decline this item."  I want to select "I decline this item."  

Here is the HTML from the web page: 

<div class="mainSelRadio">
<input value="Y" type="radio" name="/yes/ecom/ui/web/announcing/AnnouncingFormHandler.announcingForm.titleAccepted1"><input value=" "

C# - Calculate A Formula Which Changes Value Each Day?

Feb 25, 2009

I use the following columns stored in a SQL table called tb_player:

Date of Birth (Date), Times Played (Integer), Versions (Integer)

to calculate a "playvalue" (integer) in the following formula:

playvalue = (Today - Date of Birth) * Times Played * Versions

I display upto 100 of these records with the associataed playvalue on a webpage at any time.

My question is, what is the most efficient way of calculating this playvalue given it will change only once a day, due to the (today-date of birth) changing? The other values (times played & versions) remain the same.

Is there a better way than calculating this on the fly each time for the 100 records? If so, is it more efficient to do the calculation in a stored proc or in VB.NET/C#?

How To Generate The Formula

Apr 1, 2009

how to generate the formula. want to use arraylist to store and for loops to loop the formula til the system can detect which staff it should giv the ticket to..below is the scenario:this is a helpdesk each ticket they submit muz be auto assigned to a staff to attend their ticket..each staff has a different i came out wid this algorithm on hw to determine who the ticket shld go to..

for ex: i set one ticket's quota is 7%

staff A's quota - 47% staff B's quota - 35% staff C's quota - 18% so to knw how many tickets A get den B getx 1 ticket and how many tickets B get den C gets 1i came out wid a calculation like this -

Staff A - 47% / 7% = 6.7(max no.of tickets he can receive foe a period of time)
Staff B - 35% / 7% = 5
Staff C - 18% / 7% = 2.5

so first i compare A&B whr i took 6.7/5 = 1.3 -> so every 1.3 ticket A gets,B gets 1 ticket den i compare B&C whr i took 5/2.5 = 2 -> so every 2 ticket B gets,C gets 1 ticket i wanna implement this concept in my code..but i dunno how to come up wid this formula..

Select Class And Checked Radio Button?

Oct 16, 2010

I created this. This is a lesson in a class I'm takingWhat the program is trying to do is this; If the radio button for member is selected and they are under 65 they pay $10. If they are a member and 65 or over, they pay $5. If they are not a member the fee is then $20. There are 4 radio buttons: Member, Non Member, Under 65 and 65 and Over. The code below is what I had in there. VS shows no errors and the thing runs, but it produces incorrect results every time (e.g. Non Member radio with Over 65 radio answers $10).

Dim blnFee As Boolean Const decNonMem As Decimal = 20 Const decMemUnder As Decimal = 10 Const decMemOver As Decimal = 5 Select Case blnFee Case radNonMember.Checked, radOver65.Checked lblFeeAmt.Text =

I'm trying to create a calculator that does this formula : Amount=Principal*(1+InterestRate) The point of it is to Calculate the compound interest earned over however many years the user selects between 1-15 from a listbox. The user also inputs the investment & interest rate. When calculate is clicked the results show in another listbox below.

I stopped the code at Year 2 as it repeats the ElseIf to EndIf unitl selectedIndex = 15 & intYear 16.

it works for Year 1 but the problem comes with Year 2-15. it needs to take the value from the previous result in lstOutput and use it in the formula for principle.

Finding Right Formula And Refreshing Values

Dec 23, 2010

i am currently making a project which is to make a cinema screen booking system. Im a beginner of course`*My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label.*My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesnt auto refresh the price from times1 to times2. OR i click one discount radiobutton which works then another after but nothing changes and it keeps the first radiobutton's value.Okay in my menu i have a ComboBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price.I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for the chosen film.And lastly there are 3 radio buttons each with different discounts.. e.g No discount, 10% off and 25% off. If selected each gives discount to full price.A formula to work out the overall price uses all three functions/tools above.My current code for the combobox and radiobutton part is as follows: [code]
