Ex. 'Visible' property of Textbox control.

In General Declarations section of your user control add:
Private TheDropDown As Boolean

In Private Sub Usercontrol_ReadProperties add:
DropDown= PropBag.ReadProperty("DropDown", False)

In Private Sub Usercontrol_WriteProperties add:
PropBag.WriteProperty "DropDown", DropDown, False


Then after that you add:

Public Property Get DropDown() As Boolean
DropDown= TheDropDown
End Property

Public Property Let DropDown(ByVal NewValue As Boolean)
TheDropDown = NewValue
If DropDown= True Then
TheDropDown = True
Else
TheDropDown = False
End If

PropertyChanged "DropDown"
End Property

replace where i typed DropDown and TheDropDown with whatever you want to name the property of course :)

example: ShowIt and TheShowIt

Thanks Eric...this is what i was looking for. it solved my prob...

One more help pl... i have one more property by the name "FileName".. it requires the file type like "*.csv" files..

i wanted to popup "FileOpen" Dialog box.. when the FileName Property is selected... pl. help me in getting this option.

Thanks in adv...

Include Microsoft Common Dialog Control component in you form/project. Then use this code

VB Code:

Public Property Get FileName()
    CommonDialog1.Filter = "CSV Files (*.csv)|*.csv"
    CommonDialog1.ShowOpen
End Property

thanks for the help...

in this code.. when ever i draw this control from tool box to from.. this OpenDialog is poped up..

i wanted to generate this only when user select this from "Propery window".. and more over in "Propery Window" the a small button with 3 dots(...) should appear to represent that there will be a dialog box on click on this property..

Ex... 'Picture' property of the Image Control.

I am not on a computer which has VB6. I will see it tommorow when I have access to a box with VB6.

hey Venu...this should do what you're asking...

Article from microsoft knowledge base:

1) Open the UserControl project in Visual Basic.

2) From the Tools Menu, click Procedure Attributes. The Procedure Attributes dialog box appears.

3) In the Procedure Attributes dialog box, click Advanced >>. The Procedure Attributes dialog box expands to display additional attributes

4) In the Procedure ID listbox, select the name of the property.

5) In the Use This Page in Property Browser list box, select the property page to displayed for the property. Click Apply to apply this setting, then click OK to close the dialog box.

The ellipses button should now appear in the container property page. If the form hosting the UserControl is still open in your project, it may be necessary to right-click on the form (in design mode) and select "Update UserControl" to refresh the property window.

on a further note from me... you can also set the description of each property you add in the procedure attributes dialog ....

on the subject of "fileopen"...you can use an api call w/o using the control on your project (although using the api creates a dependency the same as using the control itself). i'll post again later when i have more time

have a great day Venu... :)

Thanks eric, but ;)....

i got the ellipses, but i'm getting the data Format Page along with FileOpen Dialog box page...

any idea.. how to get only FileOen Dialog.. i'm coding FileOpen in the Get Property method...
