Re: OLE DB: CDynamicAccessor and Columns order Tomasz Sowinski9-Oct-01 1:05 Tomasz Sowinski 9-Oct-01 1:05  With Jet provider, you're getting bookmarks at position 0, as Steen pointed out. You don't have to ask for them, provider just gives you bookmark for free Tomasz Sowinski -- http://www.shooltz.com Re: OLE DB: CDynamicAccessor and Columns order Steen Krogsgaard9-Oct-01 2:07 Steen Krogsgaard 9-Oct-01 2:07  Are you sure that the Jet provider gives you bookmarks no matter what? In the help it says you can set DBPROP_BOOKMARKS to VARIANT_FALSE, and I translated this into you not getting the bookmarks. I tried opening a table (i.e. through IOpenRowset, using CTable<cdynamicaccessor>) while setting DBPROP_BOOKMARKS to VARIANT_FALSE, but that gave med a DB_E_ERRORSOCCURRED with the status field set to DBPROPSTATUS_CONFLICTING - maybe I'll have to turn off DBPROP_CANFETCHBACKWARDS and DBPROP_CANSCROLLBACKWARDS? I don't want to put too much time into it if you're certain that Jet will always return the bookmark column. Cheers Steen. "To claim that computer games influence children is rediculous.

As I've mentioned, some time has passed since I was working with OLEDB for the last time. However, I remember problems with column ordinals. Our product had to work with SQLServer and Jet, we had to provide two slightly database layer .dlls, one of the differences was column ordinal handling.

I implemented other Automation objects and interfaces-CCmdTarget stuff (some creatable). Now, when trying to use the control in MFC applications, the ClassWizard does not generate wrapper for the automation objects (only the ActiveX control). This is no problem in VB test application. Is there anything extra I need to do with the *.odl file for the ClassWizard to use it effectively. VC++ compiler-based COM wrappers could be generated as usual but this is not clean and nice to has clients to do. Any help? Best regards, Paul.

Re: MFC ActiveX and Interfaces Bret Faller8-Oct-01 7:40 Bret Faller 8-Oct-01 7:40  You should have a .tlb file which in ClassWizard you can select New Class from Type Library and it will generate the cpp/h for the type-library. Also, if you don't want to have the header/cpp files you can always do an #import. Bret Faller Odyssey Computing, Inc. Re: MFC ActiveX and Interfaces 8-Oct-01 7:48 8-Oct-01 7:48  Or if you want to take life into your own hands, use the APIs directly: CLSIDFromProgID, CoCreateInstance, IDispatch::GetIDsOfNames, IDispatch::Invoke, etc. Re: MFC ActiveX and Interfaces Paul Selormey8-Oct-01 15:12 Paul Selormey 8-Oct-01 15:12  Thanks, now I get it. The ClassWizard is using the VB generated *.oca file. I used the From the Typelib and selected the *.tlb and it works. Best regards, Paul.

MotherBoard serial number ernst.maurer7-Oct-01 20:42 ernst.maurer 7-Oct-01 20:42  Hi How can I get mother-board serial number, programmaticaly? Ernst Thanx Combobox Win32 Christian Graus7-Oct-01 20:06 Christian Graus 7-Oct-01 20:06  My second attempt at this question ( Internet at work is screwed, especially for CP ). I have a combo box in Win32, and I want the edit control to work. It appears I need to catch the <enter> key being pressed and impliment the behaviour I want. Spy++ can find WM_KEYDOWN?CHAR?KEYUP being called, but it is not called to the combobox ( subclassed it, nothing ) or the parent dialog ( nothing again ). Can anyone tell me what the (%#(%(# is going on and how I am supposed to do this? Thanks. Christian As I learn the innermost secrets of the around me, they reward me in many ways to keep quiet.

Re: Combobox Win32 Michael Dunn7-Oct-01 20:34 Michael Dunn 7-Oct-01 20:34  Gotta ask the obvious first - Have you set the combo style correctly (should be drop-down, not drop-list)? --Mike-- http://home.inreach.com/mdunn/ "Listen you footwarriors, can you hold down a bit with the firing?

No messages anywhere, as above. Christian As I learn the innermost secrets of the around me, they reward me in many ways to keep quiet. Men with pierced ears are better prepared for marriage.

When you type, do the characters appear at all? Or do you just get a beep? Or both? To answer your original question, you don't have to do anything special, since the combo box manages the edit box portion itself. --Mike-- http://home.inreach.com/mdunn/ "Listen you footwarriors, can you hold down a bit with the firing?

I can add and remove strings programatically, and select them. I can type in the edit box and strings appear. When I hit enter I get the bell, but the text I have typed remains and does not appear in the list box. If the combo is supposed to handle it, it sounds like something has gone horribly wrong.

Re: Combobox Win32 Tomasz Sowinski8-Oct-01 1:29 Tomasz Sowinski 8-Oct-01 1:29  The edit control is a child of combo - are you subclassing a combo itself or edit control hosted in the combo? Tomasz Sowinski -- http://www.shooltz.com Re: Combobox Win32 Christian Graus8-Oct-01 1:59 Christian Graus 8-Oct-01 1:59  I've created a Combobox with a call to CreateWindow, with the COMBOBOX class. The resulatant HWND passed back is what I have subclassed using SetWindowLong. I don't know how to get to the edit HWND from where I am, or subclass it, and I think that is my problem.

Use Spy++ to check this; it's not documented, but remains the same since Win 3.x.

However - IE uses CTRL+B, CTRL+I, CTRL+TAB and CTRL+F4 as accelerators - and I need to get those keystrokes in the ActiveX! I tried subclassing one of IE's windows (the parent of the parent of my ActiveX's window) - and I managed to trap the WM_COMMAND that is generated by those key combinations and keep it from reaching its target. That was really fun, BUT - 1. It's a bit impolite + those commands won't work even from IE's menu right now - and I prefer not to block them completely. 2. I was wondering if the notification code used in the WM_COMMAND for those commands is the same across all version of IE, and what the chances are of it STAYING the same, in case that it is. I also thought about modifying the accelerator table that IE installed - but I didn't find any way to retrieve it (except for retrieving it directly from the resources). Any idea? Please? Thanks! Can someone help me combine articles? DanYELL7-Oct-01 13:03 DanYELL 7-Oct-01 13:03  There is a great article located here: http://www.codeproject.com/combobox/customcombo.asp I have demo project of the code implemented. It's a custom drawn CListBox. My problem is, I have text which is sometimes really short, just one line and sometimes really long, 3-4 lines. I want to expand the above article so that it has multiple lines for a row. There is an article here: http://www.codeguru.com/controls/multiline_listbox.shtml which shows how to create multiple lines for a row in a CListBox. But I am having a really hard time combining the two articles into one. Please, please, please, please, please, please, please, can someone help me combine the two articles into one demo project? I have demo projects of both. Sincerely, Danielle (an overworked graduate student) EN_MAXTEXT and CEdit controls Parish7-Oct-01 11:27 Parish 7-Oct-01 11:27  I need to know when the text in a CEdit control is too long to display in the control. The control has the ES_AUTOHSCROLL style set and is read only. The problem is that EN_MAXTEXT is only sent when the text length exceeds the value returned by GetTextLimit() as the number of chars but as the control uses a proportional font the number of chars that will fit in the control will vary depending on the actual text. So how can I do this? The text is being added programmatically. Thanks, Parish while (!asleep) code(); Re: EN_MAXTEXT and CEdit controls Tim Smith7-Oct-01 11:49 Tim Smith 7-Oct-01 11:49  You could monitor EN_CHANGE (or is it EN_CHANGED?) Get the current text. Use one of the GetTextExtentPoint32 routines to get the length of that text. Tim Smith Descartes Systems Sciences, Inc. Re: EN_MAXTEXT and CEdit controls Parish7-Oct-01 12:14 Parish 7-Oct-01 12:14  Hmmm, I was beginning to think that I would have to do the size comparison myself. This is not good, IMHO, as this fuctionality must be built into the control so, when the WS_HSCROLL is used with a multi-line control, it can determine when to enable/disable the horizontal scrollbar. Thanks for the quick reply, I'll take a look at GetTextExtentPoint32. Regards, Parish while (!asleep) code();
