Wrapping a unmanaged C++ class simwiz28-Nov-02 22:57 simwiz 28-Nov-02 22:57  Hi! I have a structure defined in my old unmanaged class, which is a output parameter of one of my methods. I want to create a managed C++ class which "wrappes" my old one.... the question is: Which Marshall Type Conversion must I use in order to pass the information of this structure to my managed class and viceversa? CODE ------------------------------------------------------------------------------ void Extract( Feature* *MyFeature); ------------------------------------------------------------------------------ Feature is the structure which is really the output of my method... Thanks in advance!!! Re: Wrapping a unmanaged C++ class Jeff J1-Dec-02 18:09 Jeff J 1-Dec-02 18:09  That would depend. Is the struct a POD type, or does it have member functions? If you could give an example of the "structure" of the struct, this would be easier to figure out.

INI support - .NET style? peterchen28-Nov-02 14:51 peterchen 28-Nov-02 14:51  Is there some INI file support (other than WriteProvateProfileString-style?) skulls don't kiss  a machito   [sighist] Re: INI support - .NET style? Nick Parker30-Nov-02 18:39 Nick Parker 30-Nov-02 18:39  Yes, however you best bet is to switch over to an XML based implementation, as this is becoming the standard for replacement of the .INI file. Nick Parker Re: INI support - .NET style? peterchen30-Nov-02 21:40 peterchen 30-Nov-02 21:40  But reading .INI file output of other programs is still allowed, yes? I still distrusts XML in terms of bloat - and is there a good XML editor anyway? i.e. one that uses the structure of the file to make editing a more sane thing than XML in notepad? skulls don't kiss  a machito   [sighist] Re: INI support - .NET style? peterchen30-Nov-02 21:42 peterchen 30-Nov-02 21:42  Um... and do you care to name a names0ace, or function names? skulls don't kiss  a machito   [sighist] Re: INI support - .NET style?

Sure, if you already have an .ini file you may wish to look at this article:Convert INI file to XML[^]. Here is another article to check out as well: Save Application Settings to XML[^]. Nick Parker Re: INI support - .NET style? leppie1-Dec-02 3:34 leppie 1-Dec-02 3:34  Look at <appname>.config files as well as Dynamic properties in WinForms. Also, System.Configuration namespace.

I only understand c#, so please post a snippet of code to do this in c#. how do I use this in c#?

The "icons" for the code outlining ("+" and "-") have been replace by a small square and a weird "L" shapped character. Has anyone else experienced this? It almmst looks like the font used for the +/-'s has changed from Arial to Wingdings!!

(Suggestion: I really like solutions along the lines of "change value x in ini file to 42!!". Like that would be good.) Mike Stanbrook mstanbrook@yahoo.com Re: Outline Icons James T. Johnson28-Nov-02 13:24 James T. Johnson 28-Nov-02 13:24  Yep, happened to me. Like leppie said, it was video driver problems with full acceleration enabled. Knocking it down a tick fixed it for me. I got the full fix about a week later when ATI released version 02.3 of its Catalyst drivers -- I have an ATI Radeon 7500. IIRC the problem was caused from the previous drivers not being WinXP SP1 compatible. James - out of order - Re: Outline Icons MStanbrook28-Nov-02 15:27 MStanbrook 28-Nov-02 15:27  Interesting. I too am using a Radeon 7500, however I am under Windows2000. I'll fool with the video and see if that has any effect. Thanks gang. Mike Stanbrook mstanbrook@yahoo.com Re: Outline Icons MStanbrook28-Nov-02 16:05 MStanbrook 28-Nov-02 16:05  Yee haw!! Updated Video Driver worked like a charm!! Thanks for the nudge in the right direction.. Mike Stanbrook mstanbrook@yahoo.com Image size varies on different computers (not resolution setting) Paul Silvernail28-Nov-02 3:34 Paul Silvernail 28-Nov-02 3:34  Hi All I have a bitmap loaded as the background in a user control. The control was placed in a form and sized to cover the form's entire client area. All of this was done with designer, not dynamically. When viewed on a different computer, the bitmap image is smaller than the client area. Is this because different devices have different x-y pixel ratios? Can someone show me how to dynamically size the form so that the client area matches the picture size? I think it would be easier to size the image, but I do not want to distort the image size or quality. Thank you in advance for any guidance. Paul Re: Image size varies on different computers (not resolution setting) Paul Silvernail28-Nov-02 3:57 Paul Silvernail 28-Nov-02 3:57  oops I can't believe I stumbled on the answer soon after posting my question.

The dll was made as a Class Library project and the Debug.WriteLine code is output when run from that assembly but not from a new assembly. It looks like the when the dll is loaded from the seperate assembly it says no symbols loaded. The symbol file for the dll is in the referenced directory however.
