I have a textbox that requires the user to input the value of the Value-Added Tax of that certain area. I tried testing 12.5%. The string is converted to decimal then divided by 100 so 12.5/100 = .125. But when the program writes the value to a file, 0 is writen. not .125
View 23 RepliesDim y as integer
dim x as double = 125 / 60
y = Convert.ToInt32(x) 'removes decimals
That method works, it removes all the numbers after the decimal.
But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?
I have tested all the possible solutions i can think of, but I always run into a lot of errors
As my Christmas week side-project I thought I'd knock up a quick console app that I can run from the windows Start-up folder.
The application is going to delete some unwanted Global Corporate Desktop Icons (I like to run a clean desktop - is this common?) and Reset the Windows 7 Theme to my lovely Visual Studio 2010 graphics.
I have read the reasons why this shouldn't be done pro grammatically for the user but I feel this case is different as every morning I am manually deleting the icons and resetting the theme (policy is not stopping this - just reapplying it every morning) so I though this little side project could save me time in the long term.
I am deleting the Icons OK but I am struggling to set my theme ala:
Dim key As RegistryKey = My.Computer.Registry.CurrentUser.OpenSubKey("SoftwareMicrosoftWindowsCurrentVersionThemes", True)
[Code]....
This is setting the registry key correctly but not applying it. Ultimately I may try a simple Wallpaper Set but I would like to use the theme if possible!

I have a code snippet that I want to run when the app is closing. So, I used FormCLosing event. But now i wanna place a confirmation message for exiting. Like, if the user clicks the Exit(X) button, there'll be a prompt, if he clicks NO, then the app will not close and revert to previous state. Now I find that hard to achieve using FormClosing event. because it'll get executed no matter what button the user clicks.

View 4 RepliesI made a change to a project and hve induced a major problem. I have warnings and errors now, but I can still debug the project with the "last successful build" Iwould like to just revert everything to that build but I can't find a way to eliminate the problems I induced or find a way to go to a earlier build. Hopefully I can get back to an earlier version or I will loose the entire project as I can no longer get to the designer.
View 5 RepliesIf i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g
If VarWholeNumber MOD 10 = 1 Then
......
Endif
But if i have a whole number with format "0.00" how can i only check if the last 2 digits after the decimal is a mod of 10 regardless of what the whole number sides value is.
So something like
If VarWholeNumber's ".00" MOD 10 = 1 Then
.......
Endif
How could I could this?

i have three cells in a datagridview third cell gives the result of multiplying first and second cell.When i reload or populate this data from datatable into that datagridview value comes like 40.00. with two decimals. For example
58.00 -------->i need only 58
58.78--------->i need exact 58.78
The only problem is to remove the decimals if they are 0.
I am using two forms and the results from form 1 i want to show on form two.The results are in dB(decibel). I get a long result lile 142.1233344444 dB. I want this result be like this 142.12 dB. I use value _passedText to get value from form 1 and display it on form 2 textbox results.text
passedText = Value
Results.Text = Value
What should i do to round off it in vb.net 2008.
Is this the proper way to bring up an error if the user inputs more than 2 decimals. 'Not decCost = [0-9]*.[0-9]{0,2}

View 2 RepliesI've used .NET for a long time now but I have come across something I haven't had to do before and I'm struggling to work it out. What I need to do is work with binary numbers and convert them to decimals and vice versa but not necessarily using even numbers e.g. I would like to represent a number between 0 and 2047 which can be represented with 11 binary digits. Plus I want to represent a second number between 0 and 500000 which can be represented with 19 binary digits, and a third number, fourth etc. Then I want to string the whole binary results together and split it in to sections of lets say 5 bits each and convert those back to decimal.

View 8 RepliesHow to set default two decimals place in the textbox?
View 1 RepliesI have only started programming in VB recently and I am not very good on the coding side. I have two values a and b. When I divide them, I want only the integer part to show up ignoring all the decimals and storing it into the variable c.
i.e.:
a = 24, b = 11
c = 2
Output: 2
When i add it up it doesn't add decimals.
Example: 12.5 + 1 = 13
I need it to be 13.5

View 6 RepliesTabpages: Using a button, how do I go from tabpage1 to tabpage2? I have it kind of sorted, only not: Button click tabpage1 send to back() or hide() tabpage2 show() The problem with this, is it does not actually turn the page, and the tabpage1 tab still shows at the top. Decimals: Epically basic, I guess. I have calculations that does, for example: 10/6 = 1.666666666667 How do I get it to say 1.667 only?
And Lastly, Graphs: I have a line graph. I have fixed series as a envelope for the variable series to sit in. Again, epically basic - How do I make a series that draws a line for a variable?

facing some problems to achieve what I want. I have this piece of code which is working fine. My problem is that I want to display the results of the Text Boxes 2, 5 and 8 with thousands separated by commas and only with two decimals separated by dot , e.g. 1,234,567.89. I tried using Format and other options but I was unable to get the correct result.

I'm having some difficulty formatting some of my strings, I can't see what's wrong unfortunately. I have various numbers, e.g. 100.023, 13488.323, etc in a datagridview column that I would like to be formatted so it looks like this: $123,456
Here's what I've tried so far (that isn't working):
row.Cells(1).Value = Format(row.Cells(1).Value, "{0:D0}") 'I've also tried using {0:C0}
row.Cells(1).Value = row.Cells(1).Value.ToString("$#,#")
'This one (above) comes up with an error saying it can't put an "##" in an Integer column, something like that anyway.
What is the function that replaces all commas with decimals? For e.g. 0,001 will be 0.001 and L0,001 will be L0.001
