Progress bar in status bar Ganesh Ramaswamy6-Sep-01 3:51 Ganesh Ramaswamy 6-Sep-01 3:51  Hello, I have a status bar in which i want to place a progress bar in one of the panes. For that I tried to get the size of the pane and so that i can create the progress bar in that place. I created a string table entry in the name of the pane id, added it to indicators array and used *GetItemRect* of status bar to get the size of the pane. But the size of rect it returns is always 2,0,-17,-17. i dont know why. Because of this size the progress bar is not showed properly. If i set the size manually - reasonable guess, the progress bar is shown. Can some on please tell me what am i suppose to do??? Thanks for ur time.

I'm not sure I understand your problem. If a file get uploaded with a webbrowser, there should be no differences wether it comes from a MAC or Windows... If you have an exact problem, please write, then someone might be able to help you... - Anders Money talks, but all mine ever says is "Goodbye!"

Aftering installing and opening a workspace, I noticed that the Class View is missing, I can't debug, and there is no color syntaxing for the code. You can compile, however, and execute code. I have never seen this problem before...has anybody else? I tried the MSDN knowledge base and a couple of reinstalls and reboots with no luck.

Mine looks like this, after adding wmh and wmc so I could have these files c++ code show up as colorized and in the class view: "cpp;cxx;c;h;hxx;hpp;inl;tlh;tli;rc;rc2;wmc;wmh" If I were to nuke this string value, I would probably have the problem you have now, except I think I would still be able to set breakpoints. If you don't see this for HKCU, check that HKEY_USERS\Default has this key. HTH. Thanks to Benner for cluing me into this.

So, i don't know how i could modificate Date1 in this way, is anybody coule explain me how to do that? thanks in advance. gerald Re: Initialize a COleDateTime object Tomasz Sowinski6-Sep-01 1:22 Tomasz Sowinski 6-Sep-01 1:22  You mean that you have a line like this in your program?

I hope you see now what i mean. gerald Re: Initialize a COleDateTime object Tomasz Sowinski6-Sep-01 2:35 Tomasz Sowinski 6-Sep-01 2:35  Just like James posted - use COleDateTime::SetDate: d1.SetDate(d2.GetYear(), d3.GetMonth(), d3.GetDay()); Year comes from d2, and month and day from d3.

Re: how to convert from device coordinates into physical coordinates Tomasz Sowinski6-Sep-01 1:37 Tomasz Sowinski 6-Sep-01 1:37  How can I convert the device coordinates into physical coordinates There's no such thing as 'physical coordinates' in GDI. You can convert between device and logical coordinates using LPtoDP and DPtoLP, but I don't think this is going to solve your problem. Check http://www.faqs.org/faqs/graphics/algorithms-faq/, item 1.02 - "How do I find the distance from a point to a line?". If distance is small, you can assume than mouse is over the line. The definition of 'small' depends on your application - you can use some tolerance in testing, for example if user clicks two pixels from the line, it may be close enough.

Re: DLL trouble in WinNT Tomasz Sowinski6-Sep-01 2:09 Tomasz Sowinski 6-Sep-01 2:09  Use the Dependency Walker (DEPENDS.EXE - it comes with VC++) program to analyze dependencies between .dlls used by your app. You'll have to copy depends.exe to NT4 machine.
