Validation problem [RESOLVED]

Hello everyone,

I need a way to avoid that a clicked control gets the control, is there a way to do it ?

This is my case, I have a text box that the only valid values are the ones that exists in a data combo, but I need to give the control to the data combo when the value in the text box is incorrect and retain the control until the user select a correct value.

Right now I can do it when I manually run the textbox1_validate event (in the keyup event), but when the user uses tab key or mouse to move to another control, I can not trap the control in the data combo.

I am using the cancel variable in the validate event, but does not work because then I can not go to the data combo,

Thanks

There is also the Lost_Focus property that you can use.

Just a thought... don't u have a textbox with a datacombo? why do u need to add a separate textbox?

and you can also code in Text1_Validate Event.. just don't use cancel... rather.. you can use If Text1 is not valid then dbcombo1.SetFocus... and on datacombos validate event you can set cancel = true if the textbox is still not valid.. :)

Thanks Dglienna and Moinkan.

Dglienna, I am gonna try to use the lostfocus event, but I don't know if over there I can use setfocus.

Moinkan, I am using the text and the data grid (exucuses, not datacombo) to simulate a multicolumn combobox, and Rigth now I am doing the same thing that you told me but, when the user click on other control the datagrid doesn't keep the control.

Thanks again

VB Code:

text1.setfocus

works!

Dglienna,

When I try to give the focus on the lostfocus event I got an error :

Run-time error '5':
Invalid procedure call or argument

This is the event code :

Private Sub MyFlexGrid_LostFocus()
If Not m_Status_Val Then
MyFlexGrid.SetFocus
End If
end sub

The m_status_val is the boolean var that says if the value is valid or not

Thanks

You have to supply the cell to focus on.

VB Code:

MyFlexGrid.textmatrix(r,c).SetFocus

DG - I've never seen setting the focus to a particular cell - do you really use that?

Dglienna,

I am using DataGrid, so that TextMatrix property does not exists

hmmm. it looked right at the time, but I was thinking of the floating textbox rather than the cell. sorry about that.

Not sure about the datagrid. I don't think you can specify individual cells. that's why I assumed that it was a flexgrid.

Just a crazy thought, but why don't you use SetCapture when you want to lock out all other controls and ReleaseCapture when you don't?

VB Code:

Option Explicit
Private Declare Function SetCapture Lib "user32" ( _
    ByVal hwnd As Long _
) As Long
 
Private Declare Function ReleaseCapture Lib "user32" ( _
) As Long

To set capture to your datagrid just call

VB Code:

SetCapture DataGrid1.hwnd

and to release it

VB Code:

ReleaseCapture
