How do I handle a closing form event? Qvicksilver28-Jun-05 5:07 Qvicksilver 28-Jun-05 5:07  Hi, I have a little problem, I have a 2-form application where I can open the second form by clicking a buttom on form1 (that works fine). but when I click the close button (the red X in the upperright corner) the form closes down, and when I click the button on form1 to open form2 again I get this error: An unhandled exception of type 'System.ObjectDisposedException' occurred in system.windows.forms.dll Additional information: Cannot access a disposed object named "frmPlot". I 'dim' form2 after the 'Windows Form Designer generated code'-region as a new Form2. and the button only call the show() function. Do I have to dim a new form2 when the button clicks? because I want the information on form2 to left there when I close it down, and when I open it up again it should still be there. My main question is: Is there a way to cancel that closing/destroy-function the closing button does and do a form2.hide() instead?

Override the OnClosing method of form2, set the Cancel property of its eventargs to true and call hide instead. File extension from PIDL Andy H28-Jun-05 3:54 Andy H 28-Jun-05 3:54  I need to be able to restrict which files are displayed in a ListView control according to the file extensions. This was fine until my customer says that they do not display file extensions! Can anyone please let me know if it is possible to get the file extsion from a given PIDL (it won't be in the display name). Re: File extension from PIDL Dave Kreskowiak28-Jun-05 4:22 Dave Kreskowiak 28-Jun-05 4:22  So what if they don't display extensions. The File and FileInfo classes will still retrieve them from the file system when you enumerate the files in a directory. Just put the full path to the file (including the filename) into the Tag property of each ListViewItem. ...unless I've missed something...

I have to do things via API calls. Re: File extension from PIDL Dave Kreskowiak28-Jun-05 10:07 Dave Kreskowiak 28-Jun-05 10:07  Same answer, only use the FileSystemObject to get the filenames.

By using Find Method, this statement could not pass: "ID=3 and Name='Tome'" And the seek method could not be used for adUseClient. How to do? Thanks! Re: ADO recordset.Find jonathan1528-Jun-05 3:41 jonathan15 28-Jun-05 3:41  Try filter. Find in ADO only accepts 1 parameter while in DAO you could have more. Seek is supposed to be its replacement but as you found thats not always suitable. Filter should do what you want. Jon Re: ADO recordset.Find rushing28-Jun-05 3:57 rushing 28-Jun-05 3:57  Thank you very much. Filter is good. Seek has error. Could you give me an example? Re: ADO recordset.Find jonathan1528-Jun-05 4:05 jonathan15 28-Jun-05 4:05  To set a filter is simple rs.filter= "myNumberField = " & myNumberVar & "" The filtered recordset is now a mini recordset which could contain 0,1 or many records based on the filter criteria. When you are done do the following to remove the filter rs.filter = "" Jon Converting String to Byte Arrays alex120528-Jun-05 0:47 alex1205 28-Jun-05 0:47  Hi, I am trying to convert a unicode string containing characters with different code page (Basically a set of hex data stored in a string). When I tried to convert them they somehow get mixed up by VB. Does anybody know of a low level way of converting strings to Byte array? I am using VB6 by the way. Thanks.

Thanks! Re: How to set default button in a winform? Dave Kreskowiak28-Jun-05 4:14 Dave Kreskowiak 28-Jun-05 4:14  That depends on what you mean by "default button". Have you looked at the AcceptButton property of the form? You also might want to set the TabOrder of the button to 0. But, that depends on what your doing with your form and on what control you want the focus to being at.

Re: find word editor using API Dave Kreskowiak28-Jun-05 4:12 Dave Kreskowiak 28-Jun-05 4:12  Uhhhh.... What? Are you trying to control Notepad or Word? Are you trying to control their Find/Find Next search boxes?

Re: find word editor using API Dave Kreskowiak29-Jun-05 0:50 Dave Kreskowiak 29-Jun-05 0:50  You left the most important detail out of your question. The DHTMLEdit control is so old, MS doesn't even have the docs for it anymore. I've never used the control, so without the docs, I can't tell you how to get it to pop up it's Find window. You might want to consider using a newer component. There's a bunch out there. But, if you want to keep using this thing, look into finding other examples of people using the control. Just Google for "DHTML Edit Control". You could probably start with this[^] example.

If i use 'Ctrl + F' key then Find Window appear in 'DHTMLedit' control. it search text properly. Then I think that it is possible using API. Do you know controls like 'DHTMLedit'?

If I have understood correctly, I should tell you that FindWindow API does not find text in a window, it finds the window itself! It gets the Caption and Class of the window and returns its Handle. Tell me if I missunderstood you. Re: find word editor using API Anonymous28-Jun-05 17:15 Anonymous 28-Jun-05 17:15  Thanks for Replying I am using following API - Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" (ByVal lpClassName As Long, ByVal lpWindowName As Long) As Long Private Declare Function GetWindow Lib "User32" (ByVal hWnd As Long, ByVal wCmd As Long) As Long Private Declare Function GetWindowText Lib "User32" Alias "GetWindowTextA" (ByVal hWnd As Long, ByVal lpString As String, ByVal cch As Long) As Long Re: find word editor using API Dave Kreskowiak29-Jun-05 0:40 Dave Kreskowiak 29-Jun-05 0:40  These functions are used to find any window and return the title bar text of that window. They will NOT help you in finding any text inside a window.
