Re: CException::GetErrorMessage causing an ASSERT Joaquín M López Muñoz26-Jun-02 7:13 Joaquín M López Muñoz 26-Jun-02 7:13  You'll have to do a little hacking to get MFC to work in a console app. In this case, chances are the lacking of a CWinApp object in your code is driving MFC nuts in its effort to locate the appropriate resources. Try declaring a CWinApp object to see it that works. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: CException::GetErrorMessage causing an ASSERT Navin26-Jun-02 7:20 Navin 26-Jun-02 7:20  Nope - already got a CWinApp object. I could just ignore this, since this app is really just a test harness, and our "real" apps are full MFC (either doc-view or dialog based), not console apps. But I want it to work right! Even if you win the rat race, you're still a rat. Re: CException::GetErrorMessage causing an ASSERT Joaquín M López Muñoz26-Jun-02 7:52 Joaquín M López Muñoz 26-Jun-02 7:52  Have you called CWinApp::InitInstance? Which is the particular ASSERT that is failing? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: CException::GetErrorMessage causing an ASSERT Navin26-Jun-02 8:03 Navin 26-Jun-02 8:03  Explicitly calling InitInstance didn't help. The assert that fails, fails from CException::GetErrorMessage. Somewehre, some function calls AfxFormatStrings, which asserts after a call to AfxLoadString fails. I guess I'll have to pour through a dialog-based or doc-view app, check out all the things that it does, and do some "emperical programming" until I find the combo that works... Even if you win the rat race, you're still a rat. AHA! Navin26-Jun-02 8:16 Navin 26-Jun-02 8:16  Figured it out. I needed to have #include "afxres.rc" in my resource includes. Even though this gets put there automatically by AppWizard in an MFC app, it does NOT get put there automatically when you have a console app, even if you check "An app that supports MFC". Guess that's what I get for relying too heavily on generated code. Even if you win the rat race, you're still a rat.

My idea is before insert one ActiveX scale it to the optimal size in the Ms Word instance.

Now i have the Variant and i don't know how to extract the SAFEARRAY from it. rechi Re: SAFEARRAY in Variant Jeremy Falcon26-Jun-02 5:48 Jeremy Falcon 26-Jun-02 5:48  This is the second time you cross-posted!

I want to know how to call ShowWindow from the InitInstance to force the dialogbox to the foreground. Thanks Re: Mutex Navin26-Jun-02 5:44 Navin 26-Jun-02 5:44  There is a really good article by Joseph M. Newcomer that deals with exactly what you're trying to do.

Re: Mutex Jeremy Falcon26-Jun-02 5:45 Jeremy Falcon 26-Jun-02 5:45  You can call SetForegroundWindow() or SetWindowPos() to do that. Jeremy L.

Settlemier 27-Jun-02 9:04  I assume you want to quit the current dialog and bring the existing dialog to the foreground. SetForegroundWindow is the right call, but its behavior in later versions of Windows will thwart you (it just flashes the item on the taskbar) unless you jump the right hoops: AttachThreadInput Here's a great article : http://www.etree.com/tech/Articles/attachthreadinput.pdf And here's some code to do it: DWORD MyThreadId=GetCurrentThreadId(); DWORD ForeThreadId=::GetWindowThreadProcessId(::GetForegroundWindow(),0); HWND hForegroundMe=0; // Get handle to the window you want to place in the foreground. // For instance use EnumThreadWindows if you know the ThreadId // (perhaps you have it saved in a shared memory?) // or use EnumWindows if you know the window text of the window // you are looking for... if (GetWindowLong(hForegroundMe,GWL_STYLE)&WS_MINIMIZE) ::ShowWindow(hForegroundMe,SW_RESTORE),::UpdateWindow(hForegroundMe); if (ForeThreadId!=MyThreadId) AttachThreadInput(ForeThreadId,MyThreadId,TRUE); ::SetForegroundWindow(hForegroundMe); if (ForeThreadId!=MyThreadId) AttachThreadInput(ForeThreadId,MyThreadId,FALSE); Form objects limit RuiSantiago26-Jun-02 5:27 RuiSantiago 26-Jun-02 5:27  Hi, i'm dealing with a form with about 250 objects, now i cannot insert any other objects. Is there a limit for objects in a form, can i solve by code? Thank you Re: Form objects limit benjymous26-Jun-02 5:32 benjymous 26-Jun-02 5:32  Do all the objects need to be on the same form, or just all be displayed? You could use property pages to split up the objects, and then display multiple property pages -- Help me! I'm turning into a grapefruit! Re: Form objects limit Roger Allen26-Jun-02 5:37 Roger Allen 26-Jun-02 5:37  If I recall, there is an artificial limit of around 255 controls per window. It may be OS based or editor based. Just can't remember. As Benjymous said, splitting up the controls onto sub-pages may be the best way to go. Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one. Re: Form objects limit RuiSantiago26-Jun-02 5:44 RuiSantiago 26-Jun-02 5:44  Well, i'm kind of new with Visual C++, i understand the function of DoDataExchange, i read a bit about DDP in MDSN, i understand the concept but i'm sure that i know how to use it, can you give me a example? Most of my objects are used with an array, and for this form i don't have a ClassWizard, i've got a parse error when i try to call it, but the aplication works. Thank you all Re: Form objects limit Roger Allen26-Jun-02 6:07 Roger Allen 26-Jun-02 6:07  Classwizard doesn't like anything unexpecetd inside the DDX AFX_DATA_MAP(...) comments. If you want to use array items, just move them outside the comment block and classwizard should be happy. If your using DDX, it would recommend sticking to control variables and not CString's etc using UpdateData() as it gives you much more control. But thats just my personal preference. Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one. Re: Form objects limit RuiSantiago26-Jun-02 6:17 RuiSantiago 26-Jun-02 6:17  ClassWizard is very happy now, about the variable type, i'm using, for the same object both control and text variables and i hope this is not the cause of my problem. About DDP, is there a easy way to use it? Oor good articles about? Thanks what's the difference...

Use this for including your own source files. #include <something> tells it to search the system include file paths (for including system things) -- Help me! I'm turning into a grapefruit! Re: what's the difference... Joel Lucsy26-Jun-02 5:44 Joel Lucsy 26-Jun-02 5:44  Yep, and you'd be suprised how many open source/unix projects get this wrong. They either use all #include <>'s or all #include ""'s. Makes one feel safe using open source programs. Joel Lucsy (jjlucsy@ameritech.net)
