Re: Messageboxes in managed C++ Nathan Blomquist26-Jan-04 14:47 Nathan Blomquist 26-Jan-04 14:47  leppie, I think his problem is not with strings. Instead it is that the preprocessor sees that MessageBox is defined as either MessageBoxA or MessageBoxU depending on build enviroment. The solution should be something like: ... // this undefines the MessageBox macro #undef MessageBox // This should now work MessageBox::Show(S"Some text",S"Some text 2"); ... Or maybe I am just on crack or something... Feel free to flame me... -Nathan --------------------------- Hmmm... what's a signature? Re: Messageboxes in managed C++ bollwerj6-Feb-04 4:41 bollwerj 6-Feb-04 4:41  Had the same problem and found the solution in one of Microsoft's articles. At the beginning of the.cpp file, after the includes, I put the following: #ifdef MessageBox #undef MessageBox #endif The problem seems to be caused by a confliction in MessageBox declarations between the .Net declaration and the one in the windows.h file.

PS Don't tell me about gethostbyaddr() . Need resolve NetBIOS rather than DNS. Thanks ---Ranger--- Namespace Extension Starting point help please Paul Farry11-Jan-04 20:42 Paul Farry 11-Jan-04 20:42  Hi, I'm trying to take an old COM component that I have source code to, and convert it to pure ManagedC++. It makes use of Direct API calls, and I can get the core of it working. I'm trying to understand the article written by Nish (Implementing Callback functions using IJW (avoiding DllImport))http://www.codeproject.com/managedcpp/cbwijw.asp[^], but I can't seem to adapt the code correctly. I'm using the RAS api, and as soon as I integrate Nish's code, I get exceptions that new and delete cannot be used. Is there an article or site somewhere that covers creation of namespace extensions (if this is infact the correct term). Any help/pointers would be greatly appreciated. Is there a similar to MFC property pages in .net UserControl? Daed8-Jan-04 2:40 Daed 8-Jan-04 2:40  Hello, I'm porting an ActiveX control into a .Net UserControl using Managed C++. What is the equivalent of ActiveX property pages in .Net? If you can give me links to articles or samples that might help me. Thank you in advance Daed Re: Is there a similar to MFC property pages in .net UserControl? leppie8-Jan-04 6:09 leppie 8-Jan-04 6:09  Look at the PropertyGrid class And just assign any (not just activx) object to it with ->SelectedObject. leppie::AllocCPArticle("Zee blog"); Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it. Re: Is there a similar to MFC property pages in .net UserControl? Daed11-Jan-04 3:36 Daed 11-Jan-04 3:36  I need more than a simple PropertyGrid, I need to call a dialog and inside this dialog i want to add controls that do specific functions on the properties. This was very easy in ActiveX controls and i am not sure how possible is this now in MC++!! UserControl properties persistency Severino4-Jan-04 3:35 Severino 4-Jan-04 3:35  Hello, I'm porting an ActiveX control into a .net UserControl using MC++. In order to support persistency with MFC based ActiveX controls there was the DoPropExchange function: is there some similar function in MC++ UserControls? I noticed that the persistency of UserControls properties seems to be embedded inside the .NET framework: if I declare a property of class Bitmap, its contents will be automatically saved inside the .resx file: if I should store a binary based property (for example the contents of a WAV file), what should I do? Any example? Regards Severino Re: UserControl properties persistency Nick Hodapp5-Jan-04 7:13 Nick Hodapp 5-Jan-04 7:13  Check out the following example; it's in VB but the concepts are identical for C++: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbwlkwalkthroughpersistingobject.asp This posting is provided “AS IS” with no warranties, and confers no rights.

Re: UserControl properties persistency Hamzeh5-Jan-04 21:06 Hamzeh 5-Jan-04 21:06  Hello: This article tells how to persist data to a file but is there another way to persist the data using the .NET environment itself like what the MFC DoPropExchange function do (internally and not to a dedicated created file) ??? Re: UserControl properties persistency leppie8-Jan-04 6:11 leppie 8-Jan-04 6:11  Apply the DesignerSerializationVisibility attribute to the Properties you need to "persist" the settings from design time to runtime. leppie::AllocCPArticle("Zee blog"); Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

I just hope to see if there are anyone who came across with the similar problem of which similar linker error could shed some light of pointing out which static libraries or files that I need to additionally include into my project.

Sometimes you have Visual Studio installed libs and Platform SDK libs. Make sure you're only pointing to one or the other. using web services in MC++ vcorn30-Dec-03 1:29 vcorn 30-Dec-03 1:29  i have made a simple web service which calculate addition of 2 numbers(managed C++ web service), i try to use it in another managed C++ application, the first attempt is successful, i add web reference to project and put url to the directory where myProgram.asmx resides, it works, i try to run the application and runs smoothly. But i try it again by creating another managed C++ application and just do the same thing...now i can't add web reference....when downloading files in progress.....boom....it can't find any web reference in the url i typed before(same url)....sometimes..if i try many times....then error message appear is IIS has encounter a problem and need to close... I wonder if i need to install something or change setting to overcome this problem..... Finally...i wonder whether i can create MC++ web service and consumed it in C# application....if yes, how?...is there any tutorial or resources for this? Thx for answers....sorry for the wordy question Re: using web services in MC++ Anthony_Yio2-Jan-04 0:40 Anthony_Yio 2-Jan-04 0:40  This sounds more like a ASP.NET than a MC++ question to me. Probably you could get an answer there. Sonork 100.41263:Anthony_Yio Re: using web services in MC++ vcorn2-Jan-04 2:35 vcorn 2-Jan-04 2:35  it shouldn't be asp since i'm using C++ , no asp.net at all Re: using web services in MC++ Anthony_Yio4-Jan-04 14:46 Anthony_Yio 4-Jan-04 14:46  But if you are developing web services with .NET, then it should involve ASP.NET, unless you are using J2EE.

FileLoadException loading managed C++ class Andy Moore22-Dec-03 7:01 Andy Moore 22-Dec-03 7:01  Hello, I have created a Managed C++ assembly that takes window snapshots to create AVI movie files. This assembly consists of a __gc class to interface with other .NET applications and a __nogc inner class that makes calls to the Win32 API for the UI and Video For Windows calls to create the AVI. I am using IJW for all native class. From a C# application, I attempt to call the constructor for my __gc class in the Managed C++ assembly. This works great on Windows XP, but when I try to run on Win2K Pro, I get a FileLoadException from the C++ assembly stating that it could not load an imported function. I should be able to call the native VFW and Win32 API functions using IJW from a managed C++ class? Any suggestions or advice you could provide would be greatly appreciated. Thank You, Andrew Moore
