WTL howto use the CWindow base class Remon Spekreijse23-Jul-01 21:19 Remon Spekreijse 23-Jul-01 21:19  I use several dialogs in my project that are hosted in a splitter pane. The dialogs are created with new and create. They show up normal. Then I like to put them in a list or assign it to a general member. Something like this: In some class: CWindow * m_pWindow = NULL; In another class: CLocProp *pdlgProp = new CLocProp; pdlgProp->Create(m_hWnd); // here pdlgProp is send with sendmessage as a LPARAM (pointer is casted) // in the class with the messagehandler: m_pWindow = (CWindow*) lParam; delete m_pWindow; // Debug assetion that this pointer is not valid In the good old MFC days this was not a problem. With all the template stuff it gets difficult to hold a grip of this Windows stuff. Is it save to cast it to a CWindow*? If not, how should this be done? What if I want to put dialogs of a different type in a list. Then I need a common base class (CWindow). Also, if I don't send the dialog through the lParam parameter, An assign it to CWindow* directly after its creation and then delete it, I also get the assertion. Please help! HELP !!! HELP!!!

If you still have the dsp file (the actual project file), open that instead and a new dsw will automatically be generated. -------------- "Aagh!! I'm a victim of a Random Act of Management!"

Maybe you are just running too many apps at the same time...? Try to shut down VC and delete all auto-generated files in the project dir(after backing them up, of course;) ): dsw, clw, aps, ncb, opt, plg etc. Also delete all temporary files in the Release & Debug directories. Then open the dsp and recompile. This usually helps when VC starts acting strange... -------------- "Aagh!! I'm a victim of a Random Act of Management!"

Dao SQL? otvac23-Jul-01 13:26 otvac 23-Jul-01 13:26  When I set the m_strFilter on an SQL query as m_pSet->m_strFilter="[MyStringField] ="+"'"+MySearchString+"'"; Everything work great unless there is an apostrophe in MySearchString. Then the Jet engine coughs and sputters to a halt. Any ideas on how to handle CStrings with single qoutes in them? Richard Re: Dao SQL?

Displaying Bitmpas On Win32 Apps dark12023-Jul-01 13:07 dark120 23-Jul-01 13:07  I'm a little confused, maybe someone can point me in the right direction. I have never done bitmaps in win32 apps before, and no I don't mean I've never put a bitmap in a dialog, or toolbar, I mean displaying on the actual app. I need help because I have a project due in a week or so, and need to display a certain bitmap in the app. Yes, I took training, but you tend to forget what you don't need over the years, and I need to know what header file to insert into the main program source file. I REALLY NEED HELP ON THIS ONE. "The world doesn't care about your self esteem.

Jase Jennings23-Jul-01 12:55 Jase Jennings 23-Jul-01 12:55  Hi, I want to learn how to create a toolbar which docks on the desktop, similar to the LiveTask bar used with Creative Soundblaster products. I want to be able to autohide, and add other menus / controls to it. The thing i have in mind is also similar to the office startup toolbar or even the windows start menu bar that pops up at the bottom of your screen. Whats it called and where can i find some sample code / further reading ? Thanks Jase Re: Dockable Desktop Toolbars ?

PostMessage and MSG handler Jon Marcus23-Jul-01 12:52 Jon Marcus 23-Jul-01 12:52  I have a regular DLL using MFC and within this DLL is a worker thread. While this thread is running, it is trying to update a dialog box (owned by the DLL) with some information on the thread's progress. Everything works OK except that the WPARAM and LPARAM values I pass to the dialog are not getting through, and are always zero. Is there some special reason for this?

Can you post the code running in worker thread that updates the dialog? Tomasz Sowinski -- http://www.shooltz.com Re: PostMessage and MSG handler Jon Marcus24-Jul-01 12:06 Jon Marcus 24-Jul-01 12:06  thanks, but I didcovered a much simpler way to do this, which works well. CPropertySheet in wizard mode Jon Sagara23-Jul-01 11:23 Jon Sagara 23-Jul-01 11:23  Is is possible to disable the Cancel button, or to get rid of it? I tried to GetDlgItem(IDCANCEL)->EnableWindow(FALSE), but the program asserted. Thanks, Jon Sagara "Go Banana!" -- Ralph Wiggum Re: CPropertySheet in wizard mode Paolo Messina23-Jul-01 12:27 Paolo Messina 23-Jul-01 12:27  Are you calling it in your sheet's OnInitDialog? Or where? And what code asserts? ASSERT(::IsWindow(m_hWnd)) ? Re: CPropertySheet in wizard mode Jon Sagara23-Jul-01 12:40 Jon Sagara 23-Jul-01 12:40  Paolo, Thanks for the response. Your question triggered my brain, and I figured it out. Here is the correct (or working, anyway) code: pSheet->GetDlgItem(IDCANCEL)->EnableWindow(FALSE); Thanks again, Jon Sagara "Go Banana!" -- Ralph Wiggum
