DS problem Mihail5-Jul-01 6:02 Mihail 5-Jul-01 6:02  Lately my DS crashes consistently when I am closing the DS or randomly while working. The error messages are: "The instruction at 0x77fca8ac referenced memory at 0x00000005. The memory could not be written." After OK the above message the next one is : "The instruction at 0x6c371351 referenced memory at 0x00000004. The memory could not be read." I posted the addresses for example only. Anybody ran into this? I tried to reinstall VC++ (6.0) with no results, OS W2k. Thanks Mihail Re: DS problem Carlos Antollini5-Jul-01 6:17 Carlos Antollini 5-Jul-01 6:17  Do you installed some new product lately? I have the Visual Studio 6.0 working really fine in my W2K. I had no problems, never..... I remember that I had these type of message in Visual Basic when I used the Formula one Grid.... Cheers!!!! Carlos Antollini. Re: DS problem Mihail5-Jul-01 6:54 Mihail 5-Jul-01 6:54  Just XML Spy, but I had this problem before. Don't use the the Formula One Grid, I am using the Stingray Objective grid. ado and excel Gérald Mercet5-Jul-01 5:39 Gérald Mercet 5-Jul-01 5:39  i would like to know if anybody has created an application which use ado method to catch excel database. i'm new in visual c++ programming, so if you could help me gerald Re: ado and excel User 98855-Jul-01 6:16 User 9885 5-Jul-01 6:16  The easiest way would be to setup an "ODBC Data Source" using the control panel ODBC Data Sources app. Then you can use it the same way as with any other ODBC data source. To see your tables in excel from the ODBC interface, you have to select the rows that make up the table and then use "Insert | Name | Define" to give a name for the table. The text in the first row would be identified as column names. I hope this helps you. Please let me know if you face further problems. --Thomas modified 29-Aug-18 21:01pm. Re: ado and excel Carlos Antollini5-Jul-01 6:26 Carlos Antollini 5-Jul-01 6:26  What Thomas says is certain, I want to add that the name of the sheet is the name of the table. If in the sheet the first row have not the name of the field, you can reference this in yourt querys with numbers. "Select 0,4,5 From Sheet01" where 0 is the field 0.... Best Regards and Good Luck!!! Carlos Antollini. Re: ado and excel 5-Jul-01 21:41 5-Jul-01 21:41  Are you sure that ADO isn't better and more flexible than ODBC? But it's just a proposition, it's the first time i have to do this kind of job, so.... gerald Re: ado and excel User 98856-Jul-01 12:07 User 9885 6-Jul-01 12:07  Instead of using the ODBC driver for ADO, you can also use the - Microsoft.Jet.OLEDB.4.0 provider and use Engine Type as "Excel 8.0". There are examples in MSDN that does that, but they are mostly VB examples. But, with ODBC driver, your code will be much easier as you can use "DSN=DataSource;" as the connect string for the ADO Recordset open. Note: I have never used Excel through the Jet ADO driver. So I am not sure of the syntax. Personally, I prefer using OLEDB over ADO in VC++. I use the OLEDB consumer templates. If you want to check this out you can look in MSDN for CDataSource CSession CDynamicAccessor classes. -- Thomas modified 29-Aug-18 21:01pm. Re: ado and excel 5-Jul-01 7:23 5-Jul-01 7:23  try this: http://support.microsoft.com/support/kb/articles/Q278/9/73.ASP Header notifications? 5-Jul-01 4:53 5-Jul-01 4:53  Hi All, I have a CMyListCtrl (derived from) CListCtrl on a CMyPropertyPage (derived from CPropertyPage). In CMyListCtrl I try to handle several header control notifications: ON_NOTIFY(HDN_BEGINTRACK, 0, OnHeaderBeginTrack) ON_NOTIFY(HDN_ENDTRACK, 0, OnHeaderEndTrack) ON_NOTIFY(HDN_BEGINDRAG, 0, OnHeaderBeginDrag) ON_NOTIFY(HDN_ENDDRAG, 0, OnHeaderEndDrag) ON_NOTIFY(HDN_DIVIDERDBLCLK, 0, OnHeaderDividerDoubleClick) ON_NOTIFY(HDN_ITEMCHANGING, 0, OnHeaderItemChanging) ON_NOTIFY(HDN_ITEMCLICK, 0, OnHeaderItemClick) The problem is I get some of the notifications, but not others. I get the BEGIN/END TRACK/DRAG notifications, but I do NOT get the DIVIDERDBLCLK, ITEMCHANGING, or ITEMCLICK notifications? I can use ON_NOTIFY_REFLECT(LVN_COLUMNCLICK, OnListColumnClick) in place of the HDN_ITEMCLICK notification, but I don't understand why I'm not getting the header notifications. If I handle the HDN_DIVIDERDBLCLICK notification in CMyPropertyPage, I do get the notification, so it looks like the header control sends some of its notifications to the CListCtrl, and others to the CPropertyPage? It also seems like by the time the HDN_DIVIDERDBLCLICK notification is received, the header (or listctrl) has already done the default resizing of the header columns, but that's what I wanted to customize. Any ideas or suggestions? Thanks - Sean McKinnon mailto:sean.mckinnon@kvs.com Re: Header notifications? Tomasz Sowinski5-Jul-01 5:15 Tomasz Sowinski 5-Jul-01 5:15  I've checked this with Spy++ on Win2000. My app wasn't UNICODE, but when I clicked on header, list control received HDN_ITEMCLICKW (not HDN_ITEMCLICKA mapped via #define to HDN_ITEMCLICK). It seems that this is the case with other notifications as well. Tomasz Sowinski -- http://www.shooltz.com Re: Header notifications? 9-Jul-01 5:03 9-Jul-01 5:03  Yes! That was it, thank you! - Sean How can I hide a list control item? 5-Jul-01 2:50 5-Jul-01 2:50  Is it possible to hide a list control item with CListCtrl::SetItemState as described in the MSDN Library: "An application might change other state bits to disable or hide the item, or to specify an overlay image or state image." Re: How can I hide a list control item? Tomasz Sowinski5-Jul-01 4:06 Tomasz Sowinski 5-Jul-01 4:06  It looks like bug in the documentation. They only list the following item styles: LVIS_CUT, LVIS_DROPHILITED, LVIS_FOCUSED and LVIS_SELECTED. The closest thing to item hiding would be setting the state to LVIS_CUT - Windows shell uses this style to display file icon after 'Cut' command.

Catching Access Violations Nick Blumhardt4-Jul-01 16:27 Nick Blumhardt 4-Jul-01 16:27  Hi All, I've just discovered I can handle the various kernel exceptiions, like 0xc0000005 : Access Violation by using: catch (...) { } Is it common knowledge that this can be done? Why doesn't everyone handle GPFs etc like this (nicely)... By the way, does the caught exception have a type? nb Re: Catching Access Violations Nick Blumhardt4-Jul-01 17:42 Nick Blumhardt 4-Jul-01 17:42  Answered my own question- you can only catch them with the ellipsis if anyone's interested in this, check out _set_se_translator() in the MSDN cheers \ nb ActiveX controls in Internet Explorer Derek Waters4-Jul-01 16:21 Derek Waters 4-Jul-01 16:21  Hi, I'm creating an ActiveX control to be embedded into a web page. This control contains a child dialog with a number of controls in it. The problem is that certain key presses are not received by this child dialog, specifically, TAB, cursor keys and (importantly) Backspace. I understand that certain key presses such as TAB and cursor keys require PreTranslateMessage to be overridden in the COleControl derived class. I have done this. I also know that I should be calling LockInPlaceActive on the control when it is activated so that I can capture these WM_KEYDOWN messages, but when I debug this control when it is embedded into a web page (and viewed in Internet Explorer), LockInPlaceActive always returns FALSE. Does Internet Explorer disallow in place active? Is there any way that pressing Backspace in a child Edit control of the ActiveX control will actually edit the text rather than returning to the previous web page? Thanks in advance. Derek Waters Re: ActiveX controls in Internet Explorer Michael Dunn4-Jul-01 16:26 Michael Dunn 4-Jul-01 16:26  You need to implement IInputObject to receive those keystrokes. Search for IInputObject in MSDN - I know I've come across at least one article that describes how to do what you want. --Mike-- http://home.inreach.com/mdunn/ "Holding the away team at bay with a non-functioning phaser was an act of unmitigated gall.
