when using waitchild method, got run time error, Type mismatch: 'TestObject.WaitChild'

[StefanieYou]

HI there,

I'm writing test cases in VB, and when using the method waitchild, got run time error, Type mismatch: 'TestObject.WaitChild' 

below is the script:

Sub Test39
set TestObject=Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly
If TestObject.WaitChild(lstbox_LandingSurface,15000) Then
  log.Message "the model browser is ready"
  call Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.txtBlock_LandingSurface.ClickR(30,10) 'choose landing surface node and edit feature
  Else
End if
End Sub

the parent object here is Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly, and the child is Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.txtBlock_LandingSurface

am I giving the wrong parameter?

thanks,

stefanie

Yo Stefanie!

The error "Type mismatch: 'TestObject.WaitChild" it is because the result of .WaitChild() its an object not true/false value (boolean)

https://support.smartbear.com/testcomplete/docs/reference/test-objects/members/common-for-all/waitch...

what you can do is to add .Exists in Your If condition to properly check the state of the object.

Example:

if(Aliases.Cube.CubeTransitionBox.WaitChild("WLbl_ValidationImage", 50000).Exists) {
// code
}

The result from .Exist method is a boolean value.

Hope this will help Yoy.

Hi Wamboo,

thanks for helping!

you're right! I re-edit the script but the still got an error

Sub Test39

TestObject=Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly
If TestObject.WaitChild(lstbox_LandingSurface,15000).Exists Then
log.Message "the model browser is ready"
call Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.txtBlock_LandingSurface.ClickR(30,10) 'choose landing surface node and edit feature
Else
End if
End Sub

so I adjusted again:

Sub Test36
If Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.WaitChild(Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.lstbox_LandingSurface,15000).Exists Then
log.Message "the model browser is ready"
call Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.txtBlock_LandingSurface.ClickR(30,10) 'choose landing surface node and edit feature
Else
End if

End Sub

then tried this again:

Sub Test37
If Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.WaitChild(lstbox_LandingSurface,15000).Exists Then
log.Message "the model browser is ready"
call Aliases.Inventor.AInventor.Pane_ModelBrowser.lst_Assembly.txtBlock_LandingSurface.ClickR(30,10) 'choose landing surface node and edit feature
Else
End if

End Sub

Can you try to use the method name, .WaitAliasChild instead of .WaitChild ?

check this topic for more information:

WaitChild requires two completely different sets of parameters than WaitAliasChild.  I think @Wamboo is correct here... you're using the wrong method.

But beyond that, your error on TestObject is probably due to being unable to find the object you're assigning to TestObject as well. You can't call "WaitChild" on an object that does not exist.  So, you may need to do additional tests for existance further up the tree.

@tristaanogre @Wamboo it works when using waitAliasChild, thanks a lot!!

@tristaanogre I still have a question, what do you mean when you said "WaitChild requires two completely different sets of parameters"?

thanks,

Sorry, my bad... I was thinking "FindChild"
