Right Click Menus in Windows

[Spectre5000]

I am building an application in VB 6.0 that will allow a user to add, edit, change, and delete client information
that is stored in the database. Part of this information is user telephone information. A user can have more
than one telephone number, so when I retrieve this information I load it into an MS Flex Grid control. Now, the
person who is performing the maintenance should be allowed to add, change, and delete telephone information. My question
is this:

How do you build popup menus? I need to have a menu come up when the user right-clicks on the grid when the app is in
add or edit mode. I know how to code the event firing, but how do you create the menu?

Also, is there a way to make the flex grid editable? Like when the user selects a cell, let the user enter information
directly into that cell?

To create popup menus, use the menu editor just like you normally would to create a menu along the top of the window. Lets say you make a menu called File (mnuFile) that has a few options under it. To pop that menu up with the right click event of the mouse, under the MouseUp event of your form or control, add the code:


If Button = 2 then
PopupMenu mnuOptions
End If




play around with that and see if it works. there is no inherent way to make a flexgrid editable, but you can make it look that way with a little trick- what you have to do is create a textbox that is hidden. when a user clicks on a given cell, move the textbox to that cell's position with its height and width, make sure the textbox has no bordering, then make it visible. sound fun? i thought it was pretty cool anyway. If you need source for this just let me know, i'm sure i have it around here somewhere! good luck!

oops! i just noticed that i refered to the popup menu as mnuFile in my text and then copied code that pops up mnuOptions. i meant to say mnuFile there too! sorry!

Choose the mousdown event of your msflegrid and put this code in it. I am doing the same thing. This will allow a popup menu when you right click anywhere within the msflexgrid


Private Sub nameofgrid_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)

On Error Resume Next

If Button And vbRightButton Then
PopupMenu nameofyourmenue
End If
End Sub

I'm doing the same thing - right click menu when you click on the grid. But how do you create a popup menu? Is 'PopupMenu' buildin flexGrid function or I need to create my own popup. I use divs to create a popup menu but apparently, with z-index, the popup won't go above the grid so mypopup menu is invisible when I right click on the grid

Thanks

where can i get the menu editor to create a popup menu???

Hi,

In VB go to tools and select menue ditor, or just press ctrl + E. You will get the menu builder. Then start to create your menu there. The name you give it is the name you should use in the previous code I have sent you.



Thanks

Do it the same way you create any menu in VB(Tools... Menu Editor) then set the Visible property of the Top level item to False.

The MSFlexGrid doesn't inherently allow you to edit data in a cell. Here is the code that illustrates a workaround, using a textbox.

Place a textbox on a form and set the following properties

Appearance = 0 'Flat
BorderStyle = 0 'None
Height = 375
Left = 1560
TabIndex = 1
Text
Top = 240
Width = 1455

And a MSFlexGrid control with the following properties

Height = 2895
Left = 600
TabIndex = 0
Top = 720
Width = 4215
Rows = 5
Cols = 5

Now paste the following code into the form



private Sub MSFlexGrid1_DblClick()
GridEdit Asc(" ")
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.SelStart = 1000
Case else
Text1 = Chr(KeyAscii)
Text1.SelStart = 1
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
MSFlexGrid1 = Text1
Text1.Visible = false
End If
End Sub

private Sub MSFlexGrid1_GotFocus()
If Text1.Visible then
MSFlexGrid1 = Text1
Text1.Visible = false
End If
End Sub

private Sub Text1_KeyDown(KeyCode as Integer, Shift as Integer)
Select Case KeyCode
Case vbKeyEscape
Text1.Visible = false
MSFlexGrid1.SetFocus
Case vbKeyReturn
MSFlexGrid1.SetFocus
Case vbKeyDown
MSFlexGrid1.SetFocus
DoEvents
If MSFlexGrid1.Row < MSFlexGrid1.Rows - 1 then
MSFlexGrid1.Row = MSFlexGrid1.Row + 1
End If
Case vbKeyUp
MSFlexGrid1.SetFocus
DoEvents
If MSFlexGrid1.Row > MSFlexGrid1.FixedRows then
MSFlexGrid1.Row = MSFlexGrid1.Row - 1
End If
End Select
End Sub

private Sub Text1_KeyPress(KeyAscii as Integer)
'noise suppression
If KeyAscii = vbKeyReturn then KeyAscii = 0
End Sub
