Add a dll file to using VC++ and use its functions ktnk19-Jul-15 4:03 ktnk 19-Jul-15 4:03  When i try to add a Dll file into the project ,using Add Reference-->under properties .The Dll file was created VC6. The followwing error was shown Could not add reference: ..\..\\ for one of the reasons , -Targets a higher of the.net framework -Not a.Net assembly, -Not a registered ActiveX control suggest how to use the dll in the project Re: Add a dll file to using VC++ and use its functions Richard Andrew x6419-Jul-15 7:00 Richard Andrew x64 19-Jul-15 7:00  The error message is telling you the reason. The DLL created in VC6 is not a .NET assembly. If you want to use it in your project, you will have to use P/Invoke. EDIT: Since this is the C++/CLI forum, I forgot to mention that you can also call the DLL functions directly from C++. But there is no way to add it as a .NET reference. The difficult we do right away... ...the impossible takes slightly longer. modified 19-Jul-15 14:16pm. c++ Member 1184600718-Jul-15 2:47 Member 11846007 18-Jul-15 2:47  d.

Is C++/CLI also open source with the new open source .Net? vickoza17-Jul-15 4:56 vickoza 17-Jul-15 4:56  With the new open source .Net implementation is there an open source implementation of C++\CLI?

John Schroedl17-Jul-15 9:39 John Schroedl 17-Jul-15 9:39  Not sure exactly which part of .NET you're asking about but they are not open-sourcing the C++/CLI compiler.

Is there any change to C++\CLI is Visual Studios 2012 and beyond? vickoza13-Jul-15 9:40 vickoza 13-Jul-15 9:40  Also does C++\CLI support C++ 11 and 14 feature that are also supported by the native C++ 11 complier Re: Is there any change to C++\CLI is Visual Studios 2012 and beyond? Richard MacCutchan13-Jul-15 23:18 Richard MacCutchan 13-Jul-15 23:18  Check the Microsoft documentation: https://msdn.microsoft.com/en-us/library/aa187916.aspx[^]. delete all label in windows form CLI TheCaptain1012-Jul-15 1:45 TheCaptain10 12-Jul-15 1:45  Hi I want delete or remove or clear all label from my form how can I do this? please give me an example. Re: delete all label in windows form CLI Richard MacCutchan12-Jul-15 2:19 Richard MacCutchan 12-Jul-15 2:19  Please do not repost. I gave you a suggestion to your original question. Re: delete all label in windows form CLI TheCaptain1012-Jul-15 3:35 TheCaptain10 12-Jul-15 3:35  Unfortunately I don't understand your suggestion. Please explain more and give me a example. Thanks. Re: delete all label in windows form CLI Richard MacCutchan12-Jul-15 6:59 Richard MacCutchan 12-Jul-15 6:59  See http://stackoverflow.com/questions/15186828/loop-through-all-controls-on-a-form-even-those-in-groupboxes[^]. It's C# but the principle is the same. Re: delete all label in windows form CLI TheCaptain1012-Jul-15 8:48 TheCaptain10 12-Jul-15 8:48  Exactly I don'n know what I write. I barely know about windows form because I just start it. if you know equivalent of that code in c++,please help me. Re: delete all label in windows form CLI Richard MacCutchan12-Jul-15 23:11 Richard MacCutchan 12-Jul-15 23:11  If you are just starting Windows Forms you may find it easier to switch to C#. For a sample of C++ referencing Form Controls see https://msdn.microsoft.com/en-us/library/system.windows.forms.control.controls(v=vs.110).aspx?cs-save-lang=1&cs-lang=cpp#code-snippet-1[^]. Re: delete all label in windows form CLI TheCaptain1013-Jul-15 0:11 TheCaptain10 13-Jul-15 0:11  Tank you but still there is a problem! I don't access label name because it made dynamically and before that i cant access to this label. Even I know label name the compiler don't allow me to remove in that way. Re: delete all label in windows form CLI Richard MacCutchan13-Jul-15 0:17 Richard MacCutchan 13-Jul-15 0:17  Sorry, but I do not understand what you mean. If you are iterating through a collection of controls then you do not need their name. As you look at each control in the collection you get its type to check if it is a label. Then you read its content to see if it is one of the candidates for deletion. Re: delete all label in windows form CLI TheCaptain1013-Jul-15 0:21 TheCaptain10 13-Jul-15 0:21  Well,how can I get the controls type? is there any function to return this? And how I check it is label or not? Re: delete all label in windows form CLI Richard MacCutchan13-Jul-15 0:23 Richard MacCutchan 13-Jul-15 0:23  Go back to the link I gave you previously and study the documentation. Re: delete all label in windows form CLI TheCaptain1013-Jul-15 0:37 TheCaptain10 13-Jul-15 0:37  I read them but they code are in c# and I don't know equivalent of this part in c++ : " C.GetType() == typeof(System.Windows.Forms.TextBox) " c.GetType exist in c++ but "typeof(System.Windows.Forms.TextBox)" no,do you know what is it in c++? (I'm sorry that I ask a lot question.) Re: delete all label in windows form CLI Richard MacCutchan13-Jul-15 0:48 Richard MacCutchan 13-Jul-15 0:48  I have not tried this but you should be able to use the GetType method[^] and compare it against the same result from a known object of that class, something like: C++ Label ll = new Label(); if (control.GetType() == ll.GetType()) // ... remove all label in windows form c++ TheCaptain1011-Jul-15 19:33 TheCaptain10 11-Jul-15 19:33  Hi I want delete or remove or clear all label from my form how can I do this? is there any way that I can remove specific controls without it name? Re: remove all label in windows form c++ Richard MacCutchan11-Jul-15 22:57 Richard MacCutchan 11-Jul-15 22:57  You can iterate through all the controls on the form and check their type, thus identifying the labels. You can then decide whether to remove them or not.
