I want to use the string typed in the Textbox. The property "Text" of Textbox has the type "string^". I want to change it to char*. I use the TextBox->Text->ToCharArray, but it is not char* type. It is wchar_t type. How could I convert the string^ type to char*? Appreciate your reply. Thank you.

If you just launched Visual Studio and started coding then that's why you are confused. There are articles here on Code Project[^] and on MSDN that introduce managed/native issues to developers. I strongly suggest your read them. If you have read some and are still confused you should reference the article and the section that you are confused about. static_cast [modified] steve_rm17-Oct-07 17:21 steve_rm 17-Oct-07 17:21  Hello, I am new to C++, coming from C. I am using this 'static_cast<int>' and just wondering what it is used for and when is the best time to use it. Many thanks, Steve -- modified at 23:32 Wednesday 17th October, 2007 Re: static_cast Christian Graus17-Oct-07 18:01 Christian Graus 17-Oct-07 18:01  There are four templated cast operators in C++, although most people still use C style casts. You should read up on all four, there's plenty of articles on the web. You should ask your questions in the Visual C++ forum, this one is for .NET based C++.

Can tab pages be shared? BuckBrown17-Oct-07 6:07 BuckBrown 17-Oct-07 6:07  Hi, I'm using Visual Studio 2005 C++/CLI. Can this even be done? I have properties that I need to setup. I have a Form that has a tabControl on it. The tabControl contains ten tabPages (one page for each defined test). Each tabPage has another tabControl placed on it with one tabPage per instrument. Here's the deal. Every test uses an instrument that has 20 definable properties. So if I select the tabPage for Test1 I will see sub-tabPages for Instrument1, Instrument2, etc. Now I can place 20 comboBoxes on tabPageTest1.Instrument1 and then do the same for tabPageTest2.Instrument1, tabPageTest3.Instrument1, etc., but then I end up with 200 comboBoxes, each with a unique name (that I have to take the time to rename) like comboBoxAcqModeTest1, comboBoxAcqModeTest2, comboBoxAcqModeTest3, etc. What I would like to do is use the tabPage for Instrument1 as (for lack of a better term) a template that I can populate with the information for a given test and then display under the correct tab. What I have tried is when I click tabPageTest10, I populate tabPageTest1.Instrument1 and then tried BringToFront() but that didn't work. Is there a way to either bring the tabControl inside tabPageTest1 to the top of the display or copy the tabControl from tabPageTest1 to tabPageTest10? Thanks Buck Re: Can tab pages be shared? led mike17-Oct-07 6:35 led mike 17-Oct-07 6:35  BuckBrown wrote: but then I end up with 200 comboBoxes Sounds like a Bug Splat UI to me. Ever heard of TreeView, ListView and PropertyGrid? gcroot and ArrayList sGrabert17-Oct-07 0:52 sGrabert 17-Oct-07 0:52  Hello, this question may come from a very wrong approach , feel free to suggest a better way to solve this I want to store a global dynamic list of structs inside a managed code dll. First I create the array list gcroot<System::Collections::ArrayList*> parameters; parameters=new System::Collections::ArrayList(); But i get a very weired exception during runtime: Handle has not been initialized when creating the ArrayList. How can I initialize this variable the correct way? Thx for your time.. Re: gcroot and ArrayList Mark Salsbery17-Oct-07 6:04 Mark Salsbery 17-Oct-07 6:04  Is that code verbatim? If so, shoiuldn't you be using gcnew instead of new? (__gc new in managed extensions) Mark Mark Salsbery Microsoft MVP - Visual C++ Re: gcroot and ArrayList sGrabert18-Oct-07 1:29 sGrabert 18-Oct-07 1:29  Thank you for the answer, I'm fairly new to this topic (gcroot). This is the new code according to your suggestion. parameters=__gc new System::Collections::ArrayList(); But still, the same exception is raised when I try to create the ArrayList... Any idea? Re: gcroot and ArrayList Mark Salsbery18-Oct-07 9:12 Mark Salsbery 18-Oct-07 9:12  hmmm it worked for me on VS2005... Where is this code located? The gcroot<> line is at global scope - outside of any method/function, right? What about the parameters= line? Where's that at? Where does the exception get thrown? Mark Mark Salsbery Microsoft MVP - Visual C++ Re: gcroot and ArrayList sGrabert18-Oct-07 22:43 sGrabert 18-Oct-07 22:43  Yes, the gcroot<> line is at global scope. I wrote an ManagedCode-DLL based on a .NET-Assembly that is dynamically linked by a standard MFC application. The gcroot variable is created during DLL initialization (called via a procedure). Hopefully this will help you.. Currently I am working on a different approach (linked list class) to solve my problem. This seems to be the best solution as gcroot more like a "dirty" fix for something that can be solved in a more correct way, i suppose.
