yep, if you're using VB then make sure you set the SCALEWIDTH properties correctly as below or you'll get wierd results.
with this resizing thing, my apps use it, however i've set MI to only resize it's display after the size of the container window has changed by more than 10%. this reduces the API overhead associated with making a call every time the user resizes it, or in other words, instead of there being say 50 resize calls made as the user expands the map window, it only does a couple. i also provide a manual refresh/resize button for when the resize they have done does not exceeed 10%. the reason for all this, is essentially because i was encountering errors with stuff to do with simultaneous commands. if anyone has robust code for on the fly resizing, then i'd appreciate being able to check it out. it's just that i found it to be too unstable so i chose the 10 percent solution. ash. -----Original Message----- From: CRISP, Paul -Syntegra UK [mailto:[EMAIL PROTECTED] Sent: Saturday, 1 March 2003 1:47 AM To: 'Windeler, David'; 'MapInfo-L (E-mail) Subject: RE: MI-L Integrated Mapping Problem David - Its not actually the picture box you are seeing, its the reparented MapInfo window. Either prevent the users resizing the form or put the following code in the forms resize event. (From the MapBasic manual) - Whether the user is able to resize the Map window depends on how you set up your application. The sample program, FindZip, places a Map window in a Visual Basic PictureBox control, so that it cannot be resized. However, you could reparent a Map window using an MDI interface, which allows the user to resize the window. Note: When the user resizes the Map window, MapInfo does not automatically reset the map's contents to fill the new window size. Therefore, if your application allows the user to resize the Map window, you must call the Windows API function MoveWindow to make the Map window conform to the new size. For example, if your Visual Basic program will run under 32-bit Windows, you can use the following Visual Basic Declare statement to access the MoveWindow API function: Declare Function MoveWindow Lib "user32" _ (ByVal hWnd As Long, _ ByVal x As Long, ByVal y As Long, _ ByVal nWidth As Long, ByVal nHeight As Long, _ ByVal bRepaint As Long) As Long When the user resizes the Map window, call MoveWindow. In Visual Basic, a resize event triggers the Form_Resize(�) procedure; you could call MoveWindow from within that procedure, as shown in the following example. Dim mHwnd As Long mHwnd = Val(mapinfo.Eval("WindowInfo(FrontWindow(),12)")) MoveWindow mHwnd, 0, 0, ScaleWidth, ScaleHeight, 0 The number 12 corresponds to the MapBasic identifier WIN_INFO_WND. ScaleWidth and ScaleHeight are properties of a Visual Basic form, representing the form's current width and height. Note: The ScaleMode property must be set to Pixels, so that ScaleWidth and ScaleHeight represent pixel measurements.

I run a query and wish to display the results in a PictureBox frame. I have no problem doing this. However, when I resize the pictureBox control using the Form's ReSize event, I notice that the PictureBox contents (the results of the query displayed as a browser) do no resize. I was wondering how I would go about resizing the PictureBox contents when the form is resized. David Windeler Hons. BSc. Geo, GIS Apps.
