Here is the code which I have written in vb6...it is showing error in text1.setfocus
Private Sub Text1_Lostfocus()
s1 = Text1.Text
flag = 0
If Text1.Text = "" Then
flag = 1
End If
For i = 1 To Len(s1)
l = Mid(s1, i, 1)
If IsNumeric(l) = True Then
flag = 1
Exit For
End If
Next i
If flag = 1 Then
MsgBox "Enter valid input"
Text1.ForeColor = vbRed
Text1.SetFocus
End If
End Sub
Do not have this code in LostFocus, instead try to have it in the Validate event, there would be an cancel parameter to the event, if you set Cancel = True (means the cursor will not exit the control) you need not do setfocus
Try the following:
Private Sub Text1_Validate(Cancel As Boolean)
If IsNumeric(Text1.Text) = False Then
MsgBox "Enter valid input"
Text1.ForeColor = vbRed
Cancel = True
End If
End Sub
Try this if you have an empty string and you are trying to work with in in your loop you can get an invalid procedure call. skip over it all togehter don't run the loop if the text is empty.
Private Sub Text1_Lostfocus()
s1 = Text1.Text
flag = 0
If Text1.Text = "" Then
flag = 1
else
For i = 1 To Len(s1)
l = Mid(s1, i, 1)
If IsNumeric(l) = True Then
flag = 1
Exit For
End If
Next i
endif
If flag = 1 Then
MsgBox "Enter valid input"
Text1.ForeColor = vbRed
Text1.SetFocus
End If
End Sub

Private Sub Worksheet_Calculate()
Dim cell As Range
Set cell = Range("E9")
If IsNumeric(cell) Then
If cell.Value < 0 Then
ActiveSheet.Shapes("Rectangle 2").Fill.ForeColor.RGB = vbRed
Else
ActiveSheet.Shapes("Rectangle 2").Fill.ForeColor.RGB = vbGreen
End If
End If
End Sub
Hi, how can I expand this code to work with multiple shapes? I tried to just copy everything from Set cell to End if and changed up the Set cell value and shape but this didn't work.
Private Sub Worksheet_Calculate()
Dim x As Range
Set x = Range("E9")
If IsNumeric(x) Then
If x.Value < 0 Then
Sheets("DIA").Shapes("Rectangle 2").Fill.ForeColor.RGB = vbRed
Else
Sheets("DIA").Shapes("Rectangle 2").Fill.ForeColor.RGB = vbGreen
End If
End If
Dim y As Range
Set y = Range("T9")
If IsNumeric(y) Then
If y.Value < 0 Then
Sheets("DIA").Shapes("Rectangle 19").Fill.ForeColor.RGB = vbGreen
Else
Sheets("DIA").Shapes("Rectangle 19").Fill.ForeColor.RGB = vbRed
End If
End If
End Sub
This works, any smarter ways?

Currently I am working on vb6 application. I want to show data in MSFlexgrid But there is no edit Facility in MSFlexgrid Control.
Is there Any way to Edit MSFlexgrid?
There is a way using hidden Textbox. On the double click on the cell the textbox will be visible and Edit is possible here is code snippet check it
Private Sub Form_Load()
'Setting Col And row
MSFlexGrid1.Cols = 3
MSFlexGrid1.Rows = 10
'First row
MSFlexGrid1.TextMatrix(0, 0) = "ID"
MSFlexGrid1.TextMatrix(0, 1) = "Date"
MSFlexGrid1.TextMatrix(0, 2) = "Voucher Type"
'some data
MSFlexGrid1.TextMatrix(1, 0) = "E0000001"
MSFlexGrid1.TextMatrix(2, 0) = "E0000001"
MSFlexGrid1.TextMatrix(1, 1) = "01/04/10"
MSFlexGrid1.TextMatrix(2, 1) = "01/04/10"
MSFlexGrid1.TextMatrix(1, 2) = "Jrnl"
MSFlexGrid1.TextMatrix(2, 2) = "Jrnl"
End Sub
Private Sub MSFlexGrid1_DblClick()
'If MSFlexGrid1.Col = 3 Or MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then
GridEdit Asc(" ")
'End If
End Sub
Private Sub MSFlexGrid1_KeyPress(KeyAscii As Integer)
GridEdit KeyAscii
End Sub
Sub GridEdit(KeyAscii As Integer)
'use correct font
Text1.FontName = MSFlexGrid1.FontName
Text1.FontSize = MSFlexGrid1.FontSize
Select Case KeyAscii
Case 0 To Asc(" ")
Text1 = MSFlexGrid1
Text1.text = Trim(Text1.text)
Text1.SelStart = 1000
Case Else
Text1 = MSFlexGrid1
Text1.text = Trim(Text1.text)
Text1.SelStart = 1000
End Select
'position the edit box
Text1.Left = MSFlexGrid1.CellLeft + MSFlexGrid1.Left
Text1.Top = MSFlexGrid1.CellTop + MSFlexGrid1.Top
Text1.Width = MSFlexGrid1.CellWidth
Text1.Height = MSFlexGrid1.CellHeight
Text1.Visible = True
Text1.SetFocus
End Sub
Private Sub MSFlexGrid1_LeaveCell()
If Text1.Visible Then
If MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then
If Text1.text = "" Then
Text1.text = " "
End If
End If
MSFlexGrid1 = Text1
Text1.Visible = False
End If
End Sub
Private Sub MSFlexGrid1_GotFocus()
If Text1.Visible Then
If MSFlexGrid1.Col = 6 Or MSFlexGrid1.Col = 7 Then
If Text1.text = "" Then
Text1.text = " "
End If
End If
MSFlexGrid1 = Text1.text
Text1.Visible = False
End If
End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer)
'noise suppression
If MSFlexGrid1.Col <> 6 And MSFlexGrid1.Col <> 7 Then
KeyAscii = 0
End If
If KeyAscii = vbKeyReturn Then
KeyAscii = 0
End If
End Sub
Can you also try below code. This doesnt require text box.
'Put this code in MSFlexGrid Keypress Event
'===================================================
Private Sub MSFlexGrid_KeyPress(KeyAscii As Integer)
With MSFlexGrid
Select Case KeyAscii
Case 8: 'IF KEY IS BACKSPACE THEN
If .Text <> "" Then .Text = _
Left$(.Text, (Len(.Text) - 1))
Case 13: 'IF KEY IS ENTER THEN
Select Case .Col
Case Is < (.Cols - 1):
SendKeys "{right}"
Case (.Cols - 1):
If (.Row + 1) = .Rows Then
.Rows = .Rows + 1
End If
SendKeys "{home}" + "{down}"
End Select
Case Else
.Text = .Text + Chr$(KeyAscii)
'write your own keyascii Validations under
'commented lines
Select Case .Col
Case 0, 1, 2:
'if (your condition(s)) then
'accept only charectors
'Else

EDIT:

imgTarget.Refresh
Note:
Set imgTarget.Picture = imgExplode.Picture
imgTarget.Refresh
will be faster than

imgTarget.Refresh
if imgExplode is going to be around during the lifetime of imgTarget (the first command copies the image, the Set command references the image).
i've been trying to create a vb6 code that will randomize 10 questions but it's not working. i use sql as my database

Please help me i cant figure out whats wrong.
yep what's the error message?
you don't save any space with this 'with':
With Adodc2.Recordset
.Fields("IQ").Value = grade
End With
you can remove that block of code to the end (after End Select), since its in every Case statement anyway.
So compress it down to:
Adodc2.Recordset.Fields("IQ").Value = grade
why not have your option values and answers stored in the same way so you can just do a single comparison, like:
if real_ans = OptionValue then ...
for random numbers, try this:
Function Rand(max As Long, Optional Min As Long) As Long
Dim s As Single
s = Rnd(1) * (max - Min + 1) + Min - 0.5
Rand = CLng(Round(s, 0))
End Function
and put RANDOMIZE in your form_load
