>>Dear Experts,
>>
>>I have two form classes: frmBrowser and frmEntry.
>>
>>Class frmBrowser is basically used as a UI to show user existing records of a table. Its uses:
>>
>>1. It can be passed a "browse" or "search" mode. The only difference between the two modes is that "search" mode sets focus to a finder textbox and makes the form Modal.
>>2. Has buttons to allow user to Add, Edit, Delete. This will call instances of class frmEntry.
>>
>>It has the ff Init code:
>>

>>LPARAMETERS tcCAClass, tcCAClassLib, tcMode, toCallingForm
>>
>>This.oCursor = NEWOBJECT( tcCAClass, tcCAClassLib )
>>
>>WITH ThisForm
>>
>>   .LoadData()     && calls oCursor.CursorFill()
>>
>>   llLockScreen = .LockScreen
>>   .LockScreen = .F.
>>   
>>   IF PCOUNT() >= 4                                 && means this is used as Search Form
>>      .Mode = tcMode
>>      .oCallingForm = toCallingForm
>>      .oCallingForm.oReturnData = NULL   && assumes oReturnData is present
>>      .txtFind.SetFocus()
>>      .WindowType = 1 
>>   ENDIF
>>   
>>   .LoadUIControls()
>>   .ResizeForm() 
>>   .RefreshControls()
>>
>>   .LockScreen = llLockScreen
>>   
>>ENDWITH
>>

>>
>>Class frmEntry is basically a data entry form which asks for a Mode parameter and PK value (for Edit and Delete modes). It is always in MODAL mode.
>>
>>The typical scenario I want to happen is this:
>>
>>1. User elects to browse Customers, my app calls frmBrowser (instantiated from class frmBrowser) and passes the CA of Customer table, its VCX, and a "browse" mode value.
>>2. frmBrowser comes up. Good.
>>3. User elects to add, edit or delete. frmBrowser calls frmCustomer to allow user. Good.
>>4. in frmCustomer, I have a button which calls frmBrowser, but this time is passed the CA of Salesman table, its VCX, then the "search" mode value, and a ThisForm reference. This is supposed to show frmBrowser containing Salesman records, and behaves as a search form.
>>
>>Number 4 is where the problem arises, frmBrowser, which should show the Salesman table, just flashes!
>>
>>The button which calls frmBrowser from frmCustomer has this code:
>>

>>DO FORM frmBrowser WITH "mySalesmanCA", "myVCX", "SEARCH", ThisForm
>>

>>
>>So far, this is what I have noticed:
>>
>>1. If I create a form, and a button in it to call frmBrowser with the needed parameters it works fine.
>>2. But if I have frmBrowser called, which calls frmEntry, which calls frmBrowser again (as a search form), the last one just flashes.
>>
>>Been at it for a whole day with no success. I have also tried to make frmCustomer both as Modal and Non-Modal, with the same flashing result.

>To be honest, I'm not sure why you're able to set WindowType in Init the first time. Normally, when you call a form with DO FORM, you can't change WindowType. In order to be able to set WindowType, you need to call the form as a class, and then Show it, passing the WindowType parameter. However, I just did a test and was surprised to find that setting WindowType in Init worked.

Tamar,

You can set the WIndowType in the init of the form. Been doing this for years.
