Ms Word Automation margins Braulio Dez26-Jun-02 5:47 Braulio Dez 26-Jun-02 5:47  Hi, I want to know what is the useful space that I have in a document ( the X-Axis of the page)... My idea is before insert one ActiveX scale it to the optimal size in the Ms Word instance. Thanks in advance, greetings Braulio SAFEARRAY in Variant Hans Ruck26-Jun-02 5:43 Hans Ruck 26-Jun-02 5:43  I pass a SAFEARRAY through a Variant from an ATL-made COM to some VB testing program. 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. Avoiding Multiple Instances of an Application Even if you win the rat race, you're still a rat. 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.

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) Re: what's the difference...

Image Processing - now with extra cess. Win98/Win2000 compatability Mike & Mr Zocce26-Jun-02 4:26 Mike & Mr Zocce 26-Jun-02 4:26  We´ve been developing an app in win2000 using MFC. When we try to run it on win98 we get a debug assertion failure when we try to execute this line: CFormView::OnInitialUpdate(). The dialog says that the error is in dlgdata.cpp on line 43.

Nick Jacobs26-Jun-02 4:23 Nick Jacobs 26-Jun-02 4:23  Hi Gang, I'm just looking for a control that simulates the "Properties" settings similar to what VB has for their controls. Left side is the tag, right side is the description. But, you can group the items together or show them alphabetized. I'd also like to know if there are some that have an ability to limit the number of characters a user may type in. Thanks for the locations!
