For those of you interestested in mathematics you can find a root of a number in two different ways. Lets say you want to find the 5th root of 27.

Math.Sqrt is used to find square root but if I want to find cube root or 4 or 5, how I can do?
View 10 RepliesDoes anyone know how I would find the square root of a variable? I'm drawing a big blank!
View 3 RepliesMuch to my disappointment I recently discovered that VB can not calculate the cube root (or any odd root) of a negative number even though it is a real answer.For instance if you tryMsgBox((-1)^(1/3))You should get -1 because -1*-1*-1 = -1. But no, VB will return NaN, not a number.Anyways, my problem is that I'm making a graph program and the user needs to be allowed to enter any formula they want and have it evaluated so the program can graph it. But if the user enters anything with x^(1/3) or like it, it will fail.So I was wondering if anyone knows of a way around this problem, such as an extension or patch or something that will fix the issue in Visual Basic. I haven't tried VB 2010 but does anyone know if they have they fixed it yet in that version?
View 15 RepliesWell, the code I have only gives the the number IF its like 2 x 2 or 4 x 4 is in the text box (4 or 16), but if its a number that can not be multiplied together to get the value in the textbox, it has an arithmetic overflow, what can I do to make it work for all numbers?
Dim Value As Integer
Dim ValueToMultiply As Integer

I'm using VB 2010 and I'm trying to populate a combobox with a name followed by a square root, but all that I was able to obtain is a name followed by an image of a triangle with a question mark at the center. I've tried to change the font but without result.

I'm trying to display the square root symbol on a button in a windows form. I'm using the unicode U+221A which on windows character map is the root sign. When i enter this in visual basic ensure the font is the same as that in the character map (wasn't sure if that made a difference to the unicode) my button displays the eta sign instead. Any help greatly received.
This is the code i'm using to set my unicode the the buttons text property.
btnSquareRoot.Text = CChar("U+221A")
I enter a valid picture path run this code and get error in the sqrt line

Right now all I get are 404 errors when attempting this with the built in IIS server in VS2k8 and on a published website. I'm using ASP.Net 3.5 and IIS 6 if those things matter.

I'm trying to copy the directories located on a root drive (J:) to another location (c:vagtilleder..)The problem is, the first folder isn't beeing copied.Example:
J:

After the copy it should look like this at the destination:
c:vagtilleder..
ootfoldersubfolder1subfolder2
But for some reason, "rootfolder" is not created at the destination, making the destination look like this:
c:vagtilleder..subfolder1subfolder2
where the error is located? OS: Win XP Pro VB 2008 Express.
Dim copytardir As String

copytardir = ("J:")

View 1 RepliesThis is my first post on the .Net Forums - I hope I don't break any rules in the first post,I'm trying to make a VB based .Net page return a file to the user from a location external to the website.The file itself is a software setup that needs to site outside the Web Directory, basically, the page needs to pick up this file and send it to the user when the page is loaded, I've done some research into the problem and it does seem that ASP .Net will not be able to let the user download files from outside the WebDirectory (in this case, WWWROOT).
Does anyone know if this can be done? I've pasted the code I'm playying about with below - but, I wouldn't be suprised if this is completely wrong

View 4 RepliesI just made my first .net website. I'm trying to use the following line of code to load a file from the current directory ( same diredtory all the web files are in). I get a error saying file does not exist
InstallFormTemp = My.Computer.FileSystem.ReadAllText("installerform.html")
I copied the file to my c drive and chnage the line to
InstallFormTemp = My.Computer.FileSystem.ReadAllText("c:installerform.html")
it worked, but now my site has to run a godaddy's webserver, so I cannot save stuff in the c drive, just my web directory.
How can I get My.Computer.FileSystem.ReadAllText to read files from the websites current directory?
I have this code to select first node of TreeView. But when page loads the by default root node is other than first, I want to set the selected node as top most by default. Here is my code in page load but it's not working:
Dim nodes As TreeNodeCollection = TreeView1.Nodes
If nodes.Count > 0 Then
' Select the root node
TreeView1.SelectedNode = nodes(0)
End If
This gives the blue underline error on this line:TreeView1.SelectedNode = nodes(0)
The error is: "Selected Node Property is read Only"
In PowerPoint (2007 at least, but probably others), it refuses to spell check "some" text in some shapes.
I thought it was the type of shape, so changed them, this didn't fix it. So I did some experiments moving what I called "infected" text into a few boxes and saw that it was somehow attached to the text.
Taking a very simple file with known infected and uninfected sections I converted the .pptx to a .zip and opened .pptslidesslide1.xml In here text which won't spell check is inclosed with:
<a:rPr noProof="1" Text which is spelt ok, or had "ignore" pressed in inclosed with:
<a:rPr dirty="0" smtClean="0" ...
And missspelled text, that was found with:
<a:rPr dirty="0" smtClean="0" err="1" ...
I found and deleted all the noProof="1"s in the file, returned it to the countainer and opened the presentation. and everything spell check as I would expect it should, all errors in all boxes were found, without damaging the file. After saving it, I reopened the silde1.xml and found dirty="0" smtClean="0" or dirty="0" smtClean="0" err="1" in the correct places.
Now the question is, how do I use this new found knowledge to fix a file, without manualy exstracting all the slide#.xml files, opening them in a text editor and using "Replace" to fix them? That process of exstraction could be automated, but if it is possible to do from VBA within PowerPoint it would be easier.
