Re: Toolbar button state (enable/disable) Tomasz Sowinski4-Oct-02 0:05 Tomasz Sowinski 4-Oct-02 0:05  'The system' (MFC app) updates the button state during its idle update cycle. See CWinApp::OnIdle and CFrameWnd::OnIdleUpdateCmdUI (undocumented).

Can anyone help me? Thanks, in advance Gianfranco Re: Problem with CMultiRectTracker into CScrollView Tomasz Sowinski4-Oct-02 0:16 Tomasz Sowinski 4-Oct-02 0:16  Without any additional information about 'the bug', I guess you could forgot to convert from device units to logical units (with CDC::DPtoLP) in mouse event handlers.

Re: IHTMLSelectionObject Stephane Rodriguez.3-Oct-02 23:25 Stephane Rodriguez. 3-Oct-02 23:25  This tag is part of the DOM, right ? So you need to store the path traversal from the root down to this node. It's up to you to find a convenient model. AFAIK, there's no such built-in model provided in the current IE DOM. sometimes it helps to look at the IL generated code a MS guy on develop.com "answering" .NET issues Re: IHTMLSelectionObject candan7-Oct-02 15:17 candan 7-Oct-02 15:17  So the html must have begin tag and end tag,if not. I would not do this feature right? Thx your reply. Re: IHTMLSelectionObject Stephane Rodriguez.7-Oct-02 19:10 Stephane Rodriguez. 7-Oct-02 19:10  Path traversal has nothing to do with end tags. We are talking DOM IE API. That's just a matter of root node, and children. She's so dirty, she threw a boomerang and it wouldn't even come back. Re: IHTMLSelectionObject candan7-Oct-02 19:17 candan 7-Oct-02 19:17  Sorry. I misunderstand. What is DOM IE API? Where I can find examples? How can I change the bitmap of a toolbar button at runtime?

Tomasz Sowinski4-Oct-02 0:44 Tomasz Sowinski 4-Oct-02 0:44  Do you want to use any bitmap, or you just need to switch between some bitmaps you know at compile time?

Daniel Strigl4-Oct-02 2:44 Daniel Strigl 4-Oct-02 2:44  Only between bitmaps I know at compile time (like a bitmap or a bitmap in a image list). -- Nice greets, Daniel. Re: How can I change the bitmap of a toolbar button at runtime? Tomasz Sowinski4-Oct-02 2:52 Tomasz Sowinski 4-Oct-02 2:52  Use CToolBar::GetToolBarCtrl and CToolBarCtrl::AddBitmap to load bitmap from resource and append it to toolbar's image list, then CToolBar::SetButtonInfo to change the index of button's image. Bitmap should have the dimensions of your toolbar buttons, usually its 16 x 15. RGB(192, 192, 192) - light gray - is used as transparency by MFC toolbars.

I want to trap the exceptions/errors which isql throughs in messagebox dialogs. Can I trap those messages anyway out. Souchakra Re: trap errors/exceptions occured while running exe through commandline Juergen Froehlich3-Oct-02 21:13 Juergen Froehlich 3-Oct-02 21:13  Try using SQL Server 2000 commandline tool osql which is the recommended tool for running sql scripts on commandline (if you not need to connect to SQL Server 6.5 or before). All sql server 2000 commandline tool output errors on stdout/stderr and there should be no message box at least. To catch the output it is a good idea to use the -o switch which directs it to the given file. (For more options see sql server 2000 online help "Using the SQL Server Tools) Possibly the messagebox may occur because ShellExecute is used and has this (configured?) effect for the case of a stderr output? Re: trap errors/exceptions occured while running exe through commandline souchakra3-Oct-02 21:27 souchakra 3-Oct-02 21:27  Hai Juergen, Thanx for your urly response.U suggested me of using osql but, I have to use Sybase Anywhere 5.5 which has the rtdsk50 eng free to distibute.For the same I am using isql.exe.

I want my application to open all files that have the extension of ".tsx". I also would like to use DDE because I one instance of my program is always running and I do not want to run another instance. All I want is to send a message to the running instance. I am looking forward to hearing from you guys Mustafa Demirhan http://www.macroangel.com Sonork ID 100.9935:zoltrix <nobr>They say I'm lazy but it takes all my time Re: DDE Messages Stephane Rodriguez.3-Oct-02 20:12 Stephane Rodriguez. 3-Oct-02 20:12  More than one hundred native Windows apps are using DDE file association already. So I guess it's not cumbersome to find them. First thing to do is in Windows Explorer file association, check the use DDE checkbox, and type Open("%1") as DDE message, and system as Topic. This in itself in almost enough (depending then on how you handle default verbs in your apps). sometimes it helps to look at the IL generated code a MS guy on develop.com "answering" .NET issues Re: DDE Messages Mustafa Demirhan3-Oct-02 20:49 Mustafa Demirhan 3-Oct-02 20:49  In fact I did that. But when I do that, CWinApp tries to open the file on its own. But what I want is to do different things but I could not figure out how to. I overrided CWinApp::OnDDECommand () but this method is never called Mustafa Demirhan http://www.macroangel.com Sonork ID 100.9935:zoltrix <nobr>They say I'm lazy but it takes all my time Re: DDE Messages Stephane Rodriguez.3-Oct-02 21:33 Stephane Rodriguez. 3-Oct-02 21:33  You must also have this in your CWinApp implementation : // enable file manager drag/drop and DDE Execute open EnableShellOpen(); RegisterShellFileTypes(); // ... And you have MSDN articles [^]about it. From a former app I somewhat remember, I also had a WIN32 message loop scrutening for WM_DDE_xxx messages.

This is a good start for me. But I still get error messages. I added these two lines, but OnDDECommand is never called. All I get is a stupid error message: "Windows cannot find 'c:\temp\yourfile.tsx'. Make sure that you typed the name correctly, and then try again. To search a file, .....". The error message directly comes from Windows Explorer and then my program is executed. But it never calls OnDDECommand. I don't know what's going on there Mustafa Demirhan http://www.macroangel.com Sonork ID 100.9935:zoltrix <nobr>They say I'm lazy but it takes all my time Re: DDE Messages Mustafa Demirhan3-Oct-02 23:08 Mustafa Demirhan 3-Oct-02 23:08  Upps.
