So I'm trying to make this form in VB6 with just an image, and whenever you press say the "Q" key that image changes, and if you press "E" it changes to back to the previous one. Simple stuff.
Here's what I have:
Private Sub Form_KeyPress(KeyAscii As Integer)
If KeyAscii = 81 Then Image.Picture = LoadPicture("E:\Imagenes\Avatars\4.jpg")
If KeyAscii = 69 Then Image.Picture = LoadPicture("E:\Imagenes\Avatars\3.gif")
End Sub
Well, that doesn't work. What could I do to make it work? Thanks!
In reading your comment, you say that you are using the Default Image Control, there is not a Default Image Control you need to add an instance of it to your Form or just use the Forms Picture Property.
These examples work for me:
Private Sub Form_KeyPress(KeyAscii As Integer)
If (Chr(KeyAscii) = "Q" Or Chr(KeyAscii) = "q") Then Form1.Picture = LoadPicture("E:\Imagenes\Avatars\4.jpg")
If (Chr(KeyAscii) = "E" Or Chr(KeyAscii) = "e") Then Form1.Picture = LoadPicture("E:\Imagenes\Avatars\3.gif")
End Sub
and
Private Sub Form_KeyPress(KeyAscii As Integer)
If (Chr(KeyAscii) = "Q" Or Chr(KeyAscii) = "q") Then Image1.Picture = LoadPicture("E:\Imagenes\Avatars\4.jpg")
If (Chr(KeyAscii) = "E" Or Chr(KeyAscii) = "e") Then Image1.Picture = LoadPicture("E:\Imagenes\Avatars\3.gif")
End Sub

I made a userform with 10 * 4 spaces for pictures("set11", "set12", ...). At the beginning they are empty. When I click on one of the pictures they should be reset by a random picture(function getRandomPath).
The sub "clicked" works if I use a Button(start) to click. If I click a picture nothing happens. When I now click again on the Button(start), the before clicked pictures don't change no more.
Here is the relevant code:
Private Sub set11_Click()
Call clicked("1", "1") '*doesn't work*
End Sub
Private Sub set12_Click()
Call clicked("1", "2") '*doesn't work*
End Sub
Private Sub set13_Click()
Call clicked("1", "3") '*doesn't work*
End Sub
Private Sub set14_Click()
Call clicked("1", "4") '*doesn't work*
End Sub
Private Sub clicked(row As String, column As String)
Controls("set" & row & column).Picture = LoadPicture(getRandomPfad())
End Sub
Private Sub start_Click()
Call clearpictures
set11.Picture = LoadPicture(getRandomPfad()) '*works*
Controls("set12").Picture = LoadPicture(getRandomPfad()) '*works*
Call clicked("1", "3") '*works*
End Sub
Private Function getRandomPfad()
Dim random As Integer
random = Int(6 * Rnd + 1)
Select Case random
Case Is = 1
getRandomPfad = "U:\MMpic\Green.jpg"
Case Is = 2
getRandomPfad = "U:\MMpic\Blue.jpg"
Case Is = 3
getRandomPfad = "U:\MMpic\Yellow.jpg"
Case Is = 4
getRandomPfad = "U:\MMpic\Pink.jpg"
Case Is = 5
getRandomPfad = "U:\MMpic\Orange.jpg"
Case Is = 6
getRandomPfad = "U:\MMpic\Red.jpg"
End Select
End Function
I hope you can help me.
Your code must exist inside the userform. If the code is within a Module, it will not work.
Also, ensure you have named the image controls to match the names given in your code: "set11"
I found the solution, I should have repainted:
Private Sub clicked(row As String, column As String)
Controls("set" & row & column).Picture = LoadPicture(getRandomPfad())
Repaint
End Sub
But thank you for your help!
I have created a dialer in VB6 to dial a phone number. It has the following buttons: the digits 0-9, backspace, "Call", and "Disconnect". Now I want enter numbers in the form using the keypad part of the keyboard. In the text box, any key can be typed in using the keypad. But I only want the number pad to operate.
For that I checked ASCII values using the KeyPress event - seeing if the pressed key value lies in between 47 and 58. But along with the key values its ASCII values are also getting displayed in the text box.
One more thing - I have one MS Flex Grid on the form along with the dialer. So when the cursor is on the form, or if the mouse is clicked anywhere other than the text box, values don't display in the text box. So how do I always keep focus on the text box?
Dim val As Integer
Private Sub append(val As Integer)
Text1.Text = Text1.Text & val
End Sub
Private Sub Backspace_Click()
With Text1
'FOCUS TO THE TEXTBOX
.SetFocus
'PUT THE CURSOR AT THE END OF THE TEXT
.SelStart = Len(.Text)
'SEND THE KEY
SendKeys ("{BACKSPACE}")
'AND THATS IT :D
End With
End Sub
Private Sub key_0_Click()
val = 0
append val
End Sub
Private Sub key_1_Click()
val = 1
append val
End Sub
Private Sub key_2_Click()
val = 2
append val
End Sub
Private Sub key_3_Click()
val = 3
append val
End Sub
Private Sub key_4_Click()
val = 4
append val
End Sub
Private Sub key_5_Click()
val = 5
append val
End Sub
Private Sub key_6_Click()
val = 6
append val
End Sub
Private Sub key_7_Click()
val = 7
append val
End Sub
Private Sub key_8_Click()
val = 8
append val
End Sub
Private Sub key_9_Click()
val = 9
append val
End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer)
If (KeyAscii > 47 And KeyAscii < 58) Then
val = KeyAscii
append val
Else
KeyAscii = 0
' Text1.Text = KeyAscii
End If
End Sub
'Private Sub Text1_LostFocus()
' Text1.SetFocus
'End Sub
You could set the KeyPreview property on the form to true.
When you have done that, put your code in the KeyPress of the form that was in the KeyPress of the Textbox, and set the text value of the textbox, or better still move the code into a function and set it from there, that way you won't need to duplicate your code if you need it in other places.
Have a look at this and see if it helps it is the KeyPreview from MSDN
Hi,
Sorry for the delay. To use the KeyPreview for the form give this a try:
Double click on the form in the project to open it
In the properties for the form find the KeyPreview Property and set it to true
Double click on the form to bring up the code window
Select the keypress event for the form, and add the following code, or something similar.
Private Sub Form_KeyPress(KeyAscii As Integer)
Text1.Text = Text1.Text & Chr$(NrOnly(KeyAscii))
End Sub
Use the function NrOnly that Hqrls has posted as that will allow only numbers which could help you with the validation. You won't need any code in the Text1_KeyPress, the form will now handle that for you.
Give it a try and let me know if you need any other information and I'll see what I can do.
[EDIT 29/05/2014]
Hi,
I've had a bit of a play around with the code and added some bits in which I think might help. Have a look at this and see if it make sense. If you copy it into your code then make sure you back up your original code just in case you need to get back to it.
This is the code if you keep your textbox
Option Explicit
Dim val As String
Dim m_blnTextHasFocus As Boolean 'Added this, so it knows wether the the textbox
'has the focus or not
'it is so the sendkeys doesn't get stuck in a
'loop with the key presses
Private Sub append(strIn As String)
'Changed the parameter from an int to a string, so we can use it in the key press events
Text1.Text = Text1.Text & strIn
End Sub
Private Sub Backspace_Click()
'Moved the code into it's own sub
DeleteAChar
End Sub
Private Sub Form_KeyPress(KeyAscii As Integer)
'Handle a key press if the textbox doesn't have the focus but ignore the keypress if it does
If Not m_blnTextHasFocus Then
If IsNumeric(Chr$(KeyAscii)) Then
append Chr$(KeyAscii)
ElseIf KeyAscii = vbKeyBack Then
DeleteAChar
End If
End If
End Sub
Private Sub key_0_Click()
val = "0"
append val
End Sub
Private Sub key_1_Click()
val = "1"
append val
End Sub
Private Sub key_2_Click()
val = "2"
append val
End Sub
Private Sub key_3_Click()
val = "3"
append val
End Sub
Private Sub key_4_Click()
val = "4"
append val
End Sub
Private Sub key_5_Click()
val = "5"
append val
End Sub
Private Sub key_6_Click()
val = "6"
append val
End Sub
Private Sub key_7_Click()
val = "7"
append val
End Sub
Private Sub key_8_Click()
val = "8"
append val
End Sub
Private Sub key_9_Click()
val = "9"
append val
End Sub
Private Sub Text1_GotFocus()
m_blnTextHasFocus = True
End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer)
'Check the keyascii value and ignore it if it isn't numeric or backspace
If Not IsNumeric(Chr$(KeyAscii)) And KeyAscii <> vbKeyBack Then
KeyAscii = 0
End If
End Sub
Private Sub DeleteAChar()
With Text1
'FOCUS TO THE TEXTBOX
.SetFocus
'PUT THE CURSOR AT THE END OF THE TEXT
.SelStart = Len(.Text)
'SEND THE KEY
SendKeys ("{BACKSPACE}")
'AND THATS IT :D
End With
End Sub
Private Sub Text1_LostFocus()
m_blnTextHasFocus = False
End Sub
If you don't need to keep the textbox then you could replace it with a label and have a try with that. It would remove the need to keep track of if the textbox has got the focus or not. Have a go with this and see if it helps any. The only other thing is to make sure KeyPreview is turned on for the form or the keypress code will only work for the form if it has the focus.
Is the textbox the only control you want to have the focus ?
In that case you can use the following code:
Private Sub Text1_LostFocus()
Text1.SetFocus
End Sub
If there are any other controls you want to be able to have the focus as well, then you can use Text1.SetFocus in the _GotFocus() event of the controls which you do not want to have the focus
Another possible solution would be to use the _KeyPress() event of the other controls as well, and convert your current Text1_KeyPress() event to a general function which can be called by the _KeyPress() event of the other controls .. make sure though that you send the output of this general function to the correct textbox
If you post the relevant parts of your code we might be able to give a more specific answer
[EDIT]
for the answer to your original question, go with the answer of lardymonkey using keypreview on the form
an example function for allowed only numeric keys and the backspace:
Private Sub Text1_KeyPress(KeyAscii As Integer)
KeyAscii = NrOnly(KeyAscii)
End Sub
Private Function NrOnly(intAscii As Integer) As Integer
Dim intReturn As Integer
intReturn = intAscii
Select Case intAscii
Case vbKeyBack
Case vbKey0 To vbKey9
Case Else
intReturn = 0
End Select
NrOnly = intReturn
End Function
I have a ListBox on which I want to handle the mousemove event; And for that reason I'm using the following code
Private Sub AreaLB_MouseMove(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles AreaLB.MouseMove
Dim ListMousePosition As Point = AreaLB.PointToClient(Me.MousePosition)
Dim itemIndex As Integer = AreaLB.IndexFromPoint(ListMousePosition)
Dim AreaToolTip As ToolTip = ToolTip1
Dim myLB As ListBox = AreaLB
AreaToolTip.Active = True
Dim g As Graphics = AreaLB.CreateGraphics()
If itemIndex > -1 Then
Dim s As String = myLB.Items(itemIndex)
If g.MeasureString(s, myLB.Font).Width > myLB.ClientRectangle.Width Then
AreaToolTip.SetToolTip(myLB, s)
Else
AreaToolTip.SetToolTip(myLB, "")
End If
g.Dispose()
End If
End Sub
My problem is... When I'm not moving the mouse this procedure runs always when the
g.MeasureString(s, myLB.Font).Width > myLB.ClientRectangle.Width
Why that happens and how can I avoid it.
What you can do is only set the ToolTip if it isn't already the value you want it to be:
Private Sub AreaLB_MouseMove(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles AreaLB.MouseMove
ToolTip1.Active = True
Dim itemIndex As Integer = AreaLB.IndexFromPoint(e.X, e.Y)
If itemIndex > -1 Then
Using g As Graphics = AreaLB.CreateGraphics()
Dim s As String = AreaLB.Items(itemIndex)
If g.MeasureString(s, AreaLB.Font).Width > AreaLB.ClientRectangle.Width Then
If ToolTip1.GetToolTip(AreaLB) <> s Then
ToolTip1.Show(s, AreaLB)
End If
Else
ToolTip1.Show("", AreaLB)
End If
End Using
End If
End Sub
I don't want to edit some of the column in flex gird.
Flex Grid
column1, column2, .... column35
i want to edit from column1... column10 only, remaining columns i don't want to edit or type.
How to do in vb6.
I believe the MS Flex Grid was designed for displaying data and not editing. If you need to edit cell data you can accomplish it using the Flex Grid using an approach of superimposing a textbox at runtime to capture user data entry and set the "Text" property of the cell in code. Otherwise you can choose to use a different control.
Here are some examples of the aforementioned approach:
http://support.microsoft.com/kb/241355
http://www.vb-helper.com/howto_edit_flexgrid_control.html
I've made a special user control in VB6 to an editable grid. If you want I can send you a copy.
The code I use to enable to edit a cell is the follow:
Private Sub fg_KeyDown(KeyCode As Integer, Shift As Integer)
Dim Cancel As Boolean
Dim Idc As Long
Dim x
If KeyCode = vbKeyEscape And Shift = 0 Then
If Not fgLocked Then
If fgRowChanged Then
RaiseEvent BeforeRestoreBuffer
For Idc = 1 To UBound(fgBuffer)
x = fgBuffer(Idc)
fgValues(Idc, fg.Row) = x
If fgColFormat(Idc) = "*" And fgBuffer(Idc) <> "" Then
fg.TextMatrix(fg.Row, Idc) = "*******"
ElseIf fgColFormat(Idc) = "RTF" Then
fg.TextMatrix(fg.Row, Idc) = Format(fgBuffer(Idc), "")
Else
fg.TextMatrix(fg.Row, Idc) = Format(fgBuffer(Idc), fgColFormat(Idc))
End If
Next
fgRowChanged = False
RaiseEvent RestoreBuffer
End If
End If
ElseIf KeyCode = vbKeyReturn And Shift = 0 Then
NextCell
ElseIf KeyCode = vbKeyF2 And Shift = 0 Then
If Not fgLocked Then
If fgColFormat(fg.Col) = "RTF" Then
CellEditBig fgValues(fg.Col, fg.Row)
Else
CellEdit fgValues(fg.Col, fg.Row)
End If
End If
ElseIf KeyCode = vbKeyF2 And Shift = vbShiftMask Then
If Not fgLocked Then
CellEditBig fgValues(fg.Col, fg.Row)
End If
ElseIf KeyCode = vbKeyDelete And Shift = 0 Then
If Not fgLocked Then
RaiseEvent BeforeDelete(Cancel)
If Not Cancel Then
If fg.Rows = fg.FixedRows + 1 Then
fg.AddItem ""
If fgRowNumber Then fg.TextMatrix(fg.Rows - 1, 0) = fg.Rows - 1
fgValues_AddItem ""
End If
fg.RemoveItem fg.Row
If fgRowNumber Then Renumera
fgValues_RemoveItem fg.Row
LoadBuffer fg.Row
RaiseEvent AfterDelete
End If
End If
ElseIf KeyCode = vbKeyInsert And Shift = 0 Then
If Not fgLocked Then
RaiseEvent BeforeInsert(Cancel)
If Not Cancel Then
fg.AddItem "", fg.Row
If fgRowNumber Then Renumera
fgValues_AddItem "", fg.Row
RaiseEvent AfterInsert
End If
End If
Else
RaiseEvent KeyDown(KeyCode, Shift)
End If
End Sub
I am creating a excel sheet that would autocomplete a text based on the text present in a particular column. After trying to make one myself unsuccessfully, I was looking online for sample codes that I could modify and incorporate in my program. (and not plagiarize)
I downloaded Workbook1.xls from http://www.ozgrid.com/forum/showthread.php?t=144438
The code is
Option Explicit
Dim ufEventsDisabled As Boolean
Dim autoCompleteEnabled As Boolean
Dim oRange As Range
Private Sub TextBox1_Change()
If ufEventsDisabled Then Exit Sub
If autoCompleteEnabled Then Call myAutoComplete(TextBox1)
End Sub
Sub myAutoComplete(aTextBox As MSForms.TextBox)
Dim RestOfCompletion As String
On Error GoTo Halt
With aTextBox
If .SelStart + .SelLength = Len(.Text) Then
RestOfCompletion = Mid(oRange.Cells(1, 1).AutoComplete(.Text), Len(.Text) + 1)
ufEventsDisabled = True
.Text = .Text & RestOfCompletion
.SelStart = Len(.Text) - Len(RestOfCompletion)
.SelLength = Len(RestOfCompletion)
End If
End With
Halt:
ufEventsDisabled = False
On Error GoTo 0
End Sub
Private Sub TextBox1_AfterUpdate()
Dim strCompleted As String
With TextBox1
strCompleted = oRange.AutoComplete(.Text)
If LCase(strCompleted) = LCase(.Text) Then
ufEventsDisabled = True
.Text = strCompleted
ufEventsDisabled = False
End If
End With
End Sub
Private Sub TextBox1_Enter()
Set oRange = ThisWorkbook.Sheets("Sheet1").Range("f4")
End Sub
Private Sub TextBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
autoCompleteEnabled = KeyCode <> vbKeyBack
autoCompleteEnabled = ((vbKey0 <= KeyCode) And (KeyCode <= vbKeyZ))
End Sub
Private Sub CommandButton1_Click()
Unload Me
End Sub
Private Sub UserForm_Click()
End Sub
If you'd notice the line RestOfCompletion = Mid(oRange.Cells(1, 1).AutoComplete(.Text), Len(.Text) + 1), I was wondering what AutoComplete is doing here. Its not a in built function and is not defined anywhere. Still the code runs fine. I am very curious.
Thanks
The .AutoComplete is a function of the Range object - it is based on passing the text to a range that exists elsewhere on the sheet.
You can see the documentation on this function here:
http://msdn.microsoft.com/en-us/library/bb209667(v=office.12).aspx
The myAutoComplete function handles the finding of the autocomplete data against the range if it exists, and the other pieces in the code are for highlighting the correct piece of text.
