Calculating Textbox And Label Width
I am trying to figure out how to calculate how wide a label or text box needs to be to hold a string of a certain number of characters. I realize it can be done manually as the form is built. I would prefer to be able to calculate the necessary width prior to building the form.

I can get the string length using "len"; however, I have no idea how to translate the number of characters to width of the control. It would appear I need to factor in the Font Name and Font Size. I realize some Fonts have varying widths for different characters. I assume I should use the width of the "M" in my calculations.

Any suggestions as to how the combination of Font Name, Font Size and number of characters can be translated UserForm measurements would be appreciated.

Width Of Text In No-fixed Width String
How can I find the wdith of a string of text in a non-fixed width font?

I am trying to format a comment box in Excel VBA, and I can't use a carraige return, so I am trying to set the width of the comment box and then fit my text into rows and columns.

Calculating String
I have a field that is set up as text which holds the calculation formula in my database.

Legend of what the constants are
TS = Total Food + Total Service
FS = Food Sales
SS = Service Sales
PF = Port Fee
TX = Taxes

Here is an example of what I mean. Calculation Field in the database might be set to.

TS + (FS * TX) + (SS * PF)

Now in my program the user definds that
TS = 1000
FS = 700
SS = 300
TX = 8%
PF = 6%

So the formula would end up looking like this
1000 + (700 * .08) + (300 * .06)

What I need to do is get the value of this into a variable set as double, but the formual is a string. Is there an easy way of doing this. Here is some vb code that kind of shows what I mean.


VB Code:
Dim s As Double    Dim sFormula As String     sFormula = "TS + (FS * TX) + (SS * PF)"    sFormula = Replace(sFormula, "TS", "1000")    sFormula = Replace(sFormula, "FS", "700")    sFormula = Replace(sFormula, "SS", "300")    sFormula = Replace(sFormula, "TX", ".08")    sFormula = Replace(sFormula, "PF", ".06")    'I want the result of the formula go into my S    'variable but this does not work.    S = Val(sFormula)

Calculating A String Formula
I have a formula string that is stored in a database. "((<PP> - 216.81) * .01) + 6)"

I perform a replace to complete the formula like so:

sFormula = replace(rst.fields("Formula").value,"<PP>", txtPP.text)

so now the formula reads: "((396-216.81) * .01) + 6)" but is still a string.

now how can I calculate this string at runtime?

any ideas would be appreciated.

Calculating String Equations
I have tried looking through various forums trying to find out if anyone knows how to calculate a value for and equation contained in a string eg "1 + 2 + 3" to make equal to 6
One of the forums suggested Microsoft's Script Control and use it's 'Eval' function to calculate it. Unfortunately when I try to run my program it crashes. I'm using VB 5 Control Creation Edn.
as it does not seam to get as close in VB 4 Professional. (Which I have. Does anyone have any suggestions on how to either fix it or any alternative.

Calculating Length Of String
Hi,

i have a problem with displaying data in a list box neatly.This is how it looks.

computer serial number
printer serial number
computer serial number

I somehow need to calculate the string first so the vairiable 'sp' can change according to the length of the string, which should make the spacing the same. Hope this makes sense. here is my code:

List1.Clear
sp = 13
Do While Not rs.EOF

List1.AddItem "" & rs![category] & Space(sp) & rs![serial]


rs.MoveNext

Loop
rs.MoveFirst

thanks in advance

Calculating String Sums
I would like to know if there is any function in VB by which you can 'parse' a string containing a sum, like "1+1", and get a number containing the result. JavaScript has the eval() function which you can use for this purpose, but I have not been able to find any such function in VB. Any help would be greatly appreciated!

I appreciate everyones' assistance.

Number To Fixed Width Right Aligned String?
Hi All
I want to know if there is any function in VB6 which is like STR function in SQL Server.
STR function takes three arguments viz. number to be formatted, width of resulting string and decimal places required.
I want such function in VB6 where if I supply number, total width and decimal places required, I will get a string right aligned within specified width. If number is smaller, it must get padded with spaces.
I hope VB6 must be having such a basic function.
Please help
Thanx

Any help will be appreciated.

Set Form Width Based On Width Of Text
I have the following code:


Code:

For intIndex = 0 To lstText.ListCount - 1

strData = lstText.List(intIndex)

'Size report based on length of text
If TextWidth(strData) > lngWidth Then
lngWidth = TextWidth(strData)
End If

txtData.SelText = strData & vbCrLf

Next intIndex

Me.Width = lngWidth + (DATA_WIDTH_OFFSET * 2)


DATA_WIDTH_OFFSET is the length of the space between the side of the form and the side of the text. The Form_Resize automatically adjusts the width of the textbox based on the width of the form.

The problem is that it's not coming up with the correct size. The end result (the width of the form) ends up being about half the size it should be.

Is there a trick tp getting this to work properly?

Form Width Vs Flexgrid Width
Hi,
Im facing some problems in the Form resizing along with the Flex grid size.
I made a procedure, which can display the records in a flex grid from any Select statement (SQL). No.of columns ,Colomname, rows, Cellwidth everything is in run time and those are working fine

But when SQL is bringing more columns then I have to increase the form width and the Flexgrid width to show the details. The form width should be increased based on the Flexgrid width. But once form width is not increasing more than 15000 . (My Resolution is 1024)

I understand it is depending on the Screen size and If form width is more than the screen then it will not increase further.
But is it possible to have a Scroll bar in a form to show the remaining part of the grid ?
How can solve this problem ?

Pls suggest an idea

How Does WebBrowser.Height And WebBrowse.Width Translate To Form.Height And Width?
I am using Visual Basic 6, on a Windows XP SP2 machine.

I have a website that users surf using my VB application.
This application has two Forms, Form1 and Form2.
Both of these Forms have a WebBrowser object embedded in each of them.

Now, let's say that a user is browsing my website using Form1.

Some of the links on this website use the javascript window.open() method to pop open a new window.


Code:


window.open('page.htm', 'myWindow', 'width=640,height=480');



In Form1, I am using the NewWindow2 method to trap for this event:


Code:



Private Sub WebBrowser1_NewWindow2( _
ByRef ppDisp As Object, _
ByRef Cancel As Boolean)

Form2.WebBrowser1.RegisterAsBrowser = True
Set ppDisp = Form2.WebBrowser1.Object

End Sub




I want Form2 to act as the "popup" window, and honor the sizes specified by the Javascript call.

From Form2, I can get the width and height values specified by the javascript call by either

1) Query the pDisp object from the BeforeNavigate2 method


Code:



Private Sub WebBrowser1_BeforeNavigate2( _
ByVal pDisp As Object, _
ByRef URL As Variant, _
ByRef flags As Variant, _
ByRef TargetFrameName As Variant, _
ByRef PostData As Variant, _
ByRef Headers As Variant, _
ByRef Cancel As Boolean)

Debug.Print("Width: " & pDisp.Width & ", Height: " & pDisp.Height)

End Sub




2) Get CX and CY values from the ClientToHostWindow method


Code:



Private Sub WebBrowser1_ClientToHostWindow(CX As Long, CY As Long)
Debug.Print("Width: " & cstr(CX) & ", Height: " & cstr(CY))
End Sub




QUESTION What is the mathematical formula to translate the pixel values into the correct Form2.Height and Form2.Width values?

For example, if I want my Form2 to be 640 x 480 px, what is the mathematical formula to translate that into something VB can use:

For 640px X 480px...

Form2.Height = ??? (What is the formula to get this?)
Form2. Width = ??? (What is the formula to get this?)

Thank you

Difference Between Image1.Picture.Width And Image1.width
Hi,

I was wondering if someone could explain to me what the difference is
between the width propery of the picture property of an image and the width
property of the image itself.

I would have guessed that when the stretch property of an image was set to
false and an image was assigned to the picture property, that
Image1.Picture.Width and Image1.width would be the same. This is not the
case.

I need to know with what factor an image is stretched when stretched = true,
and I thought I could use these two different width properties, thinking
that Image1.width is the stretched width and Image1.Picture.width is the
actual width of the image.

Can someone help me figure this out?

Thanks in advance,
Sandra
