Hi every body!

I really need this, please help me
Thanks!

looks like GDI would be the way to go, but i'm not sure of the exact commands right now. try MSDN-ing GDI there's always something useful there.

I have a simple For..Next loop in which I declare an integer variable for use in the rest of the loop. I would expect the variable to be re-declared on every iteration, but this isn't happening - it keeps its value throughout all repetitions of the loop. Can anybody explain why this happens? Does the compiler optimise the looped declaration into one? Why would it not at least re-initialise the variable? If this is intended behaviour, does that mean it is safe to declare loop counters/exit flags within the loop body and have it behave as a method variable?
Thanks,
Jon

You didn't say if you were using VB6 or .NET but for .NET MSDN isn't terribly clear in their explaination; but the relevant part is: "If you declare a variable inside a block, and if you enter that block several times during the lifetime of the procedure, you should initialize the variable to avoid unexpected values. "
See http://msdn2.microsoft.com/en-us/library/bybkyxaz[^]

Thanks for that Richard, it is VB.NET that I'm using. Interesting behaviour, not what I would have expected, useful to know though! Cheers

Hi All,
I have a function which will format the numbers that are returned from a variable. That is, if my Resistance is 0.0189015 then it will return 0.018, and if its 0.000065 it should return 0.00006 instead of a zero.
Here is the function
======================================================================
Private Function FormatResistance(ByVal Resistance As Double) As Double
Dim PositionCount As Int16
Dim ResistanceCheck As String
Dim ResistanceString As String
Dim Resistancelength As Int16
ResistanceString = Resistance
'CStr(Resistance)
Resistancelength = ResistanceString.Length
For PositionCount = 3 To Resistancelength '' not worried if resistance is 0.xx so start in 3rd position and checking till the sixth place
If Mid(Resistance, PositionCount, 1) = 0 Then
ResistanceCheck += Mid(Resistance, PositionCount, 1) ' THis is done becos Materials like BRass has almost 0 resistance and if not formatted
'will not add to the material list because of the Isvalid Function check
End If
Next
If ResistanceCheck = "000" Then
Resistance = Format(Resistance, "0.0000")
Else
Resistance = Format(Resistance, "0.000")
End If
Return Resistance
End Function
The problem is, for the Resistance value 0.0000625 the string converted is 6.25E something.SO it fails. Any better idea to handle this ?
Or is there a simpler way of doing this ? Please help
Thanks

The simplest way is to just convert the incoming number from a numeric value to a string:
Private Function FormatResistance(ByVal Value As Double) As String
Dim psTemp As String
If Value = 0.0# Then
FormatResistance = "0"
Else
'convert double value to string
psTemp = Format(Value, "#0.000000")
If psTemp.Substring(psTemp.IndexOf(".") + 1, 3) = "000" Then
FormatResistance = psTemp.Substring(0, psTemp.IndexOf(".") + 6)
Else
FormatResistance = psTemp.Substring(0, psTemp.IndexOf(".") + 4)
End If
End If
End Function
Note that this function does not do any rounding to anything, it just truncates the number based on the examples you gave.

I am trying to make a box so that when a person types in a part number, it will search through my database and bring up a datagid with that part number, and all the other data associated with it. I haven't figured out how to link the text box with the datagrid.

Hi,friends:
we know that we can write win32 console applications with VC++6.0,then how can we just do the same thing with VB6.0?
ThanX in advance!![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

The instructions on how to create a VB6 console app by hand would take a few pages. If you are not using, or have never heard of, vbAdvance, I HIGHLY recommend you check his product out: http://www.vbadvance.com/[^]. I've been using it for a few years and I don't know how I lived without it.

I am working on a simple text editor in vb .net. My problem is one of preserving the the rtf format in the rich textbox when using the property:
RT.RightToLeft = Windows.Forms.RightToLeft.Yes
or
RT.RightToLeft = Windows.Forms.RightToLeft.No
changing the property in either direction will make text in rich texbox turn to simple text and no formatting.
I can use another hidden rich textbox to copy and paste formatted text but I am looking for a more elegant solution.
I would appreciate any help.
Thanks in advance
