Bar/Pie/Linear
Hello Everybody.... I am looking for some tutorial on Pie, Bar, and Linear graph at {B}{U} RUNTIME {/B}{/U} Using simple trigeometry concept. Let me be clear on this one... I am trying to establish 'amination' at timer control inside the picture box which it would display pie, bar, or linear graph changing at its values following via connection with another porgram.
However, I have Visual Basic Blackbook with me, I have tried to find any information including it...and Yet I have not find anything. For you who have VBBB would you know which page would that be on?
Let me know if you know any tutorial including webaddress....


Thanks in Advance

Linear Regression?
I'm reamaking an old game that I used to play called Star Fleet partly to build up my VB skills and because I should be fun!

I'm having troubles in the sector screen, it is a 10 x 10 matrix, the player can be in any cell and up to 5 torpedoes can be fired at any angle at the enemy. In order to follow a line to the target should I use linear regression and try to stay as close to the line as I can?

I tried to do some code already but it didn't work perfectly. I'll post it to see if anyone can spot my mistake.


Code:
Private Sub FireTorps(NumTorps As Integer)
Dim CountX As Integer
Dim CountY As Integer
Dim Count As Integer
Dim DistanceX(5) As Integer
Dim DistanceY(5) As Integer
Dim DiffX(5) As Single
Dim DiffY(5) As Single
Dim DistX(5) As Single
Dim DistY(5) As Single

Debug.Print "New torps"
Debug.Print "Player at " & Player.Sector.X & "," & Player.Sector.Y
Debug.Print "Torp #1 Destination" & Player.Torps(1).X & "," & Player.Torps(1).Y
Debug.Print "Torp #2 Destination" & Player.Torps(2).X & "," & Player.Torps(2).Y

For CountX = 1 To NumTorps
With Player.Torps(CountX)
DistanceX(CountX) = Player.Sector.X - .X
If DistanceX(CountX) <> 0 Then
DistX(CountX) = 1 / DistanceX(CountX)
Else
DistX(Count) = 0
End If
DistanceY(CountX) = Player.Sector.Y - .Y
If DistanceY(CountX) <> 0 Then
DistY(CountX) = 1 / DistanceY(CountX)
Else
DistY(Count) = 0
End If
Debug.Print "Torp#" & CountX & "Distance X=" & DistanceX(1) & " Diff X=" & DistX(1)
Debug.Print "Torp#" & CountX & "Distance Y=" & DistanceY(2) & " Diff Y=" & DistY(2)
.X = Player.Sector.X
.Y = Player.Sector.Y
DiffX(CountX) = .X
DiffY(CountX) = .Y
'UpdateSRS
End With
Next CountX
Sem.TorpActive = True
Debug.Print vbCrLf

For CountX = 1 To 20
For Count = 1 To NumTorps
With Player.Torps(Count)
DiffX(Count) = DiffX(Count) - DistX(Count)
.X = DiffX(Count)
DiffY(Count) = DiffY(Count) - DistY(Count)
.Y = DiffY(Count)
Debug.Print "torp#" & Count & " x=" & .X & " y=" & .Y
End With
Next Count

Linear Equations
mmmmm. I don't know if it's the right category to post this, but here I go. I found on inet, part of the code to solve Simultaneous Linear Equations. Works great for me, but I'm programming for Palm with the MobileVB from Appforge (Add IN for VB 6.0, www.appforge.com). Some of these devices don't have keys at all. Everything is done with screen touch. The problem, to summerize, is that it takes a lot of time to enter the Equations, (matrix form), even with a little keyboard I made.
Actually, there's no problem at all, if the equation is organized:

2A + 3b -c = 3 --> Enter each coefficient
... .... .... (Rest of equations)

Trouble comes for:

A/2 + A/3 + 1.5 B + 5b/8 + c/7 = 15/7
... ... ...

See what I mean? So I have been looking for a way to enter in a field box
the whole equation, and have the program organize it and simplifies it.

Thanx!

Interpolation: The Non-linear Kind
heelllllllooooooo.
ok well, i wrote a function that linearly interpolates btwn 2 .x files. the problem is, that many of my interpolations are objects such as arms and legs, and linear interpolation doesn't work. what ends up happening is the meshes get slightly skewed betweenthe 1st and last frames, since they do not stay in the same relative position. i was wondering if there is a way to interpolate, but do it in more of a circular manner. so rather than go straight between the positions, it travels in an arc so that the vertices all stay the same distance apart and from the origin of the object. this seems like it would be difficult though, and also costly to the cpu. the reason im doing this rather than just using a rotation matrix is because i first constructed the model of a person, and then just exported each part seperately such that i can now load varieties of arm and leg animations independently rather than having to export all the possible arm and leg combinations. since i export them seperately, the arm is constructed where it should be in the x file, but unfortunately that is far from the origin, and when i rotate the x file it rotates on the origin, causing the arm to be drastically out of place.so i can either reexport all the x files after moving every single moving joint of the model to 0,0,0 and then translating them in the program (which would also make it much more difficult to do the animation, since i cant see how it would look in the program) or i need a new method to use other than the d3dveclerp function that doesnt linearly interpolate. or my final choice is to just ignore it and hope it looks ok, although i think that it may cause problems if there are objects in the characters hand, since the hand would move up or down the object making it look strange.

hopefully there is a built in function or some easy way to implement better looking interpolation

Best Way For Solving Linear Algebra?
I am creating a microsoft excel workbook and need to solve a series of coupled, linear equations. I'm used to programming in FORTRAN and using Matlab, and I typically use Excel just for holding data. Does anyone have any thoughts on the best way for solving a system of equations?

My thought was to use VBA and Excel; to create a macro that can then dump the results into the spreadsheet.

any thoughts?

Solving A Set Of Linear Equations
Hi all,

As part of an application Im writing I need to solve a set of linear equations. The equations are in the form:
Ax=b.
Where b is a vector of numbers x is the vector of unknowns and A is the matrix of coefficients.
The matrix A is big (may be 3000x3000), and spars. It is also close to singular but than is by the way.

As this is a classic problem Im sure some one has done this before and there is no need for me to do it all over.
Does any one know of a *.dll or any thing else I could use to solve the problem.

Linear And Circular Intrepolation
I am working on a VB app Interface to a 3 axis stepper motor cnc / cam project, Using the Perallel Port I am able to control the 3 motors steps and direction along with haveing 6 inputs from my circuit board. I am able to move xyz positions but the code I am using has to many error steps meaning the motors will either over or under position. I need to do Linear and Circular Interpolation calculations of curX, curY, newX, newY so I can position the motors without step loss / gain. But i have been trying to find a snipit of code / formula to do this with no avail. I would appricate some help.


Thanks In advance,

Generating Non-Linear Random Numbers
I need to create random data but not on a linear scale. For example, I want random data to show how many TVs are in a household. For this example the range I am working on is 1 to 11. I could use:

randomValue = Int(Rnd * 11) + 1

But I want the random results to be based on a percentage. For this example (see below), when I create my data, I want 4% of housholds to have 1 TV, 8% to have 2 TVs, 12% have 3% and so on...

14%
28%
312%
420%
523%
613%
711%
83%
93%
102%
111%

How can I generate this? There is probably already an example here for this, but I do not know what it is called to be able to search for it.

Thank you.

Dying While Trying To Do Linear Programming In Excel
Not sure exactly where this would go but I'm totally totally stumped trying to put together this linear programming model. So here's the idea, an airplane makes 4 stops on its way from the West Coast to the East Coast. At each stop, it can purchase fuel with each stop having different prices. Given constraints, we are to determine the optimal purchase of fuel at each station to minimize fuel cost (we cannot simply fill up to full where the gas is cheapest because the heavier the plane, the faster gas burns, which wastes money). This is under the assumption that we do not know how much fuel we started with or ended with in this loop. My problem is that my linear program keeps running into a circular reference, which is expected. I created a separate table to add an extra dimension to the problem but am clueless as to how to program it. Suggestions would be nice.... here's a picture of the tables I have so far (Any help would be much appreciated):

Problem With Linear Regression Code...
Hi there,

I have a Little problem with excel, In my job I have two computers, one with the Excel 2003 Version and the other with 2002 version, and I program in the first one... I Make a simple regression code in the first (2003) computer but it doesn't work in the 2002, sends me "error 1004 in execution time". my code is here:


Code:
Sub Macro2()

Application.Run "ATPVBAEN.XLA!Regress", ActiveSheet.Range("$B$6:$B$8847"), _
ActiveSheet.Range("$A$6:$A$8847"), False, False, , "", False, False, _
False, False, , False
End Sub

So I don't know if its an error of the version... and if is... how can I fixed it?.

Thanks in advance

Calculating System Of Linear Equations
Hi everyone. I have been working on a program to balance Chemistry Equations, what I have done is set up a system of linear equations in matrix form.

For an example, see the screenshot of some sample output from my program. I would like to know what is the best method to solve a system of linear equations.

The numbers in the table are the contents of my array, each number denotes how many elements are in that compound, each column is a different variable, and each row is already set equal to zero. Like for the first row in the picture an example equation would be 1*A + 0*B - 2*C - 0*D, each letter being the coefficient of each compound...sorry if I explained more than I had to.

Thanks for the help.

Adaptation Of Non-linear Fit ActiveX Control
Help me guys, I'm trying to run a non-linear approximation method in an ActiveX control to fit my matrix function, and I don't know where to start.
I found this http://fitting.datamaster2003.com/ ActiveX non-linear least-squares fitter, and I'd like to use it in my matrix function for solving optical transmission.
What I dont get, is how I can stuff my variables, and the function, into this fitter function. My function, I call it "R" has 3 Single variables, and an Array, it goes like this

Code:
Function Rpc(Lambda As Single, SubstIndex As Single, n As Single, FilmProperty As Variant)

BB = 1
CC = 1 / SubstIndex
For I = 1 To n
R(I) = FilmProperty(2 * I - 1)
T(I) = FilmProperty(2 * I)
X(I) = (2 * 3.141592654 * R(I) * T(I)) / Lambda
'CALCULATE SINE AND COSINE TERMS FOR MATRIX ELEMENTS
C(I) = Cos(X(I))
S(I) = Sin(X(I))
Next I
'SETUP MATRIX ELEMENTS
B11 = C(1)
B12 = S(1) / R(1)
B21 = S(1) * R(1)
B22 = B11
'CHECK FOR ONE FILM
If n = 1 Then GoTo 500
For I = 1 To n
C11 = C(I)
C12 = S(I) / R(I)
C21 = S(I) * R(I)
C22 = C11
A11 = B11 * C11 - B12 * C21 'C11
A12 = B11 * C12 + B12 * C22 'C12
A21 = B21 * C11 + B22 * C21 'C21
A22 = -B21 * C12 + B22 * C22 'C22
B11 = A11
B12 = A12
B21 = A21
B22 = A22
Next I
500 CA = (AA * B11 - B22) ^ 2 + (BB * B12 - CC * B21) ^ 2
CB = (AA * B11 + B22) ^ 2 + (BB * B12 + CC * B21) ^ 2
Rpc = (CA / CB)
End Function


the fitter code goes like this:

Code:

Next
Else
MsgBox "Fitter error " & Fitter.ResultCode

End Sub


from what I understand, i need to replace Fitter_OnGetLMFunction = ... with my code...but how can I do this, and have the fit still work?

also, the sample files include vbproj files, but I can't open them with VB6, what gives?

UpperCase And LowerCase Interferring In Search &amp; Location Search
Title kinda explains it... In a listbox I have a list of words (Lots of them). Some of these words have capital letters (Names and such) but when the 'user' types in a word in the search textbox with all lowercase letters, it only lists the words that start with lowercase letters

(Example)

User Types in = "case"

Words in results:

case
casebox

Words not in results, but should show up:

Case
Case of Billy
Case of the cases of caseness (Yes, i know i'm making up words, but these are examples)

So, i need it to search for upper and lower case letters in a word, no matter where it is...



Also, I need the keysearch to pick up on words in the middle of the string...

(Example...)

User types: "case"

Should show but doesn't:

Guitar Case
Violin Case
The fifth word is Case and it won't show up!

So, I hopefully got that squared away 'clearly' if it is even remotely close to that... I'm searching for these things in a text file, using the 'Reading Records' Lesson I used in class. The notepad looks like this:

"Guitar Case"
"Case"
"Violin Case"
"case"
"casebox"
"Case of Caseness"

and i'm using this code to recall the data, so these fixes have to fit in with it:

Code:Private Sub txtboxSearch_Change()
    Dim intfile As Integer
    Dim strSearch As String
    Dim strResult As String
    Dim strPattern As String

    strSearch = txtboxSearch.Text
    intfile = FreeFile
    listbox01.Clear
    
    Open "D:Results.txt" For Input As #intfile
    Do While Not EOF(intfile)
        Input #intfile, strResult
        strpattern = strSearch & "*"
        If (strResult Like strPattern) Then
            listbox01.AddItem strResult
        End if
    Loop
    Close intfile
End Sub

This search works really well , (except for the problems above of course)... If you can't see how strPattern works, it puts what the user typed in the box with an astrik in front of it so I can use the 'Like' thingy <---(newbie word)

Thanks in advanced!

Search Line 0 Loop And Search Line1
Hi,
im new to visual basic and was wondering if anyone could help me out.
I have looked around the fourms and all the color changeing seems to deal with words as they are typed. All i want to do is create a button that changes the exsisting keywords in a rich text box red.
Heres what i am trying to do....

Button to color the word "change" in a rich text box red
Use a while loop untill end of file
Start on line 0
If the line contains the word "change" then color it red
Increment line start postion so that is starts on line this time
loop

I have been tring to do this with no luck.
I have tried to use a while loop like below, i have no idea how to get the line number or start it on line 0.
Any help would be great. Thanks.


Code:
While (Eof = False) Then
Text1.SelStart = Instr(1, Text1.Text, "change") + 1
Text1.SelLength = Len("change")
Text1.SelColor = vbRed
Loop
This code is not texted as i frogot the disk i had the code i was working on. this is what i rember of it.

Can I Make A Search Command Search Any Faster?
Ok, you all have been extremely helpful in the development of my first big project. Hopefully I will get it completed here in the next couple of days.

Anyways, I have a database with about 820,000 listings in it, my search feature work great except for the fact that its slow, i need a way, if there is any to make it search faster. Is it possible?

Here is a copy of the search command button code:

Dim strApostrophy As String, strQueryString As String
Dim strCallToFind As String

strApostrophy = "'"
strCallToFind = txtSearch.Text
strQueryString = "Call = " & strApostrophy & strCallToFind _
& strApostrophy
frmCallLookUp.datCallListings.Recordset.FindFirst strQueryString
If frmCallLookUp.datCallListings.Recordset.NoMatch Then
MsgBox "No calls matching!"
Else
frmCallLookUp.Show
End If

Coding A 'Search' Button To Search A SQL Database?
I have a SQL database titled, "Test". I have a table in this database, titled, "Customers". Within this particular table, I have quite a few fields:
Counter (primary key), FirstName, LastName, Address, City, State, Zip, CustID.

I have a form that's setup, with a variety of text boxes. In this form, I have a text box setup for the customer's First Name, the customer's Last Name, the customer's Address, another textbox for the customer's City, a ComboBox for the customer's State, and a text box for the customer's zip and customer ID.

The name of these field controls on the form are:
txtFName for the Customer's First name, txtLName for the Customer's Last name, txtAddr for the customer's Address, txtCity for the customer's City, cboState for the customer's State, txtZip for the customer's zip, and txtcustID for the customer's ID.

Now, I a few command buttons on this particular form. I have a 'Delete', an 'Update', and a 'Search' button.

I'm able to easily code the 'Delete' and 'Update' buttons fairly easily, using a Select statement to select the data that's assigned to the textField (and comboBox) controls on the form, and update the fields accordingly within the Database. Everything's been going fairly smooth, until I get to coding the "Search" button.

Beforehand, to see as to whether or not my program was able to work, I had always coded in a:

SQL = vbnullstring
SQL = "Select * From Test..Customers"
Conn.Execute SQL

Shortly after this, I end up assigning the textFields mentioned above, to displaying the information. Essentially, in a database of 10 records, the first record out of the 10 is placed onto my form, listing the customer's first name, etc...

(For the sake of simplicity, I've already coded "Previous" and "Next" buttons to cycle through the records, to see as to whether or not a record has been deleted or updated.)

However, when I try to code the 'Search' button, I'm confused as to how to apply it where a user can enter an information within any text field, and records matching such information will be listed?

For example:

A user enters a last name, and perhaps, a city. How would I go about compiling a SQL statement that will seek out only records matching such things that have been entered, be it a single field, or multiple fields?? I'm guessing concatenating a WHERE statement might help, but I totally blanked out and can't seem to get this working properly. Please help!

Search Box - Change To Multiple Search

There is about 15 websites in a drop down menu, id prefer to have a little checkbox so if the user chooses to search all 15 sites at once, then they could tick the box, enter the keyword, and search, and 15 windows or tabs etc would open, displaying the result.

Any help please, if I could add anything to the code to make this happen?

Thank you.

I Can't Search The Forum, If I Dont Know What To Search For

Search Through Recordset Using Binary Search
Hi,

Is it possible to search through a recordset using a Binary Search?

What I'm doing currently is searching through a recordset of x,y coordinates and looking for the the one that is closest to the current mouse position, and then highlighting that coordinate. It goes too slow!

Instead of looping through each and every point to check it, I'd rather generate a query that includes the x and y coordinates as well as the distance from the mouse cursor (x - xPos) ^ 2 + (y + yPos) ^ 2 (where xPos is the current x position of the mouse, and yPos is the current y position of the mouse)

Then I would like to search through this recordset using the binary search to minimize the # of calculations.......but how would you do that using binary search? How do you move to a specific location in the recordset?????

Anyone?

Search For Word, Then Continue With A Second Search
I am beating my head on the screen trying to resolve the final step in my project.

I Need to search a text.file for a specific word. "QQQQQ"

Once the word is found mark the location as startOfLine

THEN

starting at startOfLine begin a new search for a specific word "RRRRR"

Once the second word is found, mark the location as endOfLine

Using startOfLine and endOfLine, copy all the data between them to put on text5.text box




Dim nextline As String
Dim there As Integer
Open "c:myFile.txt" For Input As 1
Do While Not Eof(1)
    Input #1, nextline
    there = Instr(1, nextline, "QQQQQ")
     If there <> 0 Then
         'found string now = startOfLine
              'Start searching again beginnng with startOfLine for "RRRRR"
              'If found, then found string now = endOfLine
         Copy all data from startOfLine to endOfLine can copy to Text5.text
    Else If there = 0
        'delete last entry from queue
    End If
      Loop
 Close #1



Anyone have an example of this? or perhaps used this code in an app?

Thanks

Need Help Doing A Search
Hi,

I was wondering if anyone can help me create a search.

I have a VB program in Excel that produces a list of items and the number of items to produce is dependant on the value in a particular cell, Ar.

I have a cell for how many I need to produce and one for how much is being produced.

Does anyone know how I can get it to find a value for the Ar cell so that what is produced is close to the amount I need to Produce. It doesn't have to be exact just as close as possible.

Thank you,
Nick
