FindWindowEx Prob

[Bill Crawley]

Hi All,

I have the following code set in a form load event

FrameHwnd = FindWindowEx(Me.hwnd, 0&, "ThunderFrame", vbNullString)
calendarEndHwnd = FindWindowEx(FrameHwnd, 0&, "CalendarWndClass", vbNullString)
calendarStartHwnd = FindWindowEx(FrameHwnd, calendarEndHwnd, "CalendarWndClass", vbNullString)
cboMonthEndHwnd = FindWindowEx(calendarEndHwnd, 0&, "ComboBox", vbNullString)
cboYearEndHwnd = FindWindowEx(calendarEndHwnd, cboMonthEndHwnd, "ComboBox", vbNullString)
cboMonthStartHwnd = FindWindowEx(calendarStartHwnd, 0&, "ComboBox", vbNullString)
cboYearStartHwnd = FindWindowEx(calendarStartHwnd, cboMonthStartHwnd, "ComboBox", vbNullString)
ActCalHwnd = FindWindowEx(Me.hwnd, 0&, "CalendarWndClass", vbNullString)
cboActMonthHwnd = FindWindowEx(ActCalHwnd, 0&, "ComboBox", vbNullString)
cboActYearHwnd = FindWindowEx(ActCalHwnd, cboActMonthHwnd, "ComboBox", vbNullString)


This all works fine in a development environment both under W2K and 95. Running the compiled project on a 95 machine and it does not find the handle to set cboYearStartHwnd. The value is 0.

Does anybody have any ideas why this is so.

Hi All,

On further investigation. It really looks like the problem stems from the ThinderFrame class on the first line since the frame's handle is not Being found. I also found this to be the case when the compiled version is run on W2k. SO it all works fine in a dev environment, but as soon as it goes to a deployed state the Frame handle cannot be found.

Do you know why the handle can't be found?

I only ask this because someone else, at some point, may run into the same issue.

The Frame.hWnd property exists, therefore frames do have window handles. Why are you messing with all these FindWindowEx calls? This must be for another window, is the only answer.

Since you seem to be getting everything in the window or form, why not use EnumChildWindows instead? You do not have to know the class names, or worry about mispelling them.

In the Dev Environment, I use ThunderFrame. When Compiled windows looks for ThunderRT6Frame. Somebody shoot the guy at Microsoft who thought of this obsured thing.

*hate that friggin sprinks thing*

yeah, that's a pain, how the class names change after compilation
