Ward Re: Use .Net library in C++ quiteSmart12-Oct-06 20:54 quiteSmart 12-Oct-06 20:54  Just use the C++ in the .NET environment. Install the Visual Studio .Net and use the C++ over three jamil abou khalil MSN: jamilaboukhalil@hotmail.com Re: Use .Net library in C++ Nader Elshehabi13-Oct-06 13:02 Nader Elshehabi 13-Oct-06 13:02  Hello Sorry! You can't! .Net dlls are managed code. You know you can call unmanaged code by P/Invoke, but not vice versa. If there is a managed code that you want to use, maybe you could make it a service or a commandline console application, then you can communicate with it from your C++ program. Regards Re: Use .Net library in C++ Ward15-Oct-06 20:40 Ward 15-Oct-06 20:40  I've searched some documentation and I was able to do it. The trick is to register the .Net dll as a COM server. But to be able to register it as a COM server you must first have a tlb file of it. This tlb file you can create with the visual studio tool tlbexp.exe. From the command prompt: tlbexp dotNET.dll /win32 /out:dotNET.tlb Once you have the tlb file you can use regasm to register the .Net dll as a COM server. You will not be able to run regasm from the windows command prompt. You must launch the visual studio command prompt to do this. In the visual studio command prompt type: regasm dotNET.dll /tlb:dotNET.tlb From this point you can use the classes and functions of the .Net dll is whatever language that understands COM.

I really urge you to write an article about it in CodeProject with more details. Many people will miss this old post. I've allowed myself to bookmark this post for future referal. Really brilliant. Regards Setting a form onto a panel. JacquesDP12-Oct-06 20:12 JacquesDP 12-Oct-06 20:12  Hi all. I have the following. A form with a splitcontainer, ie.. panel1 left & panel2 right. On the left panel I have a treeview, as the user selects an item from the treeview I want to display the appropriate form onto the right hand panel. I tried the following, it compiles but fails at runtime. splitcontainer.panel2.Containers.Add(new frmToDisplay); Any help will be appreciated, thanx He who laughs last is a bit on the slow side Re: Setting a form onto a panel. AB777112-Oct-06 20:38 AB7771 12-Oct-06 20:38  try this objfrm = new frmToDisplay(); objfrm.Parent = splitcontainer.panel2; objfrm.show(); or splitcontainer.panel2.Controls.Add(new frmToDisplay); Hope that works fine for u Thanks & Regards, Pramod "Everyone is a genius at least once a year" Re: Setting a form onto a panel. JacquesDP12-Oct-06 21:11 JacquesDP 12-Oct-06 21:11  Thanx for the quick reply. Both examples compiles fine but I recieve the following error at runtime. "Top level control can not be added to a control." Not sure what it means or how to make the panel top level control He who laughs last is a bit on the slow side Re: Setting a form onto a panel.

Andrei Ungureanu12-Oct-06 21:17 Andrei Ungureanu 12-Oct-06 21:17  Hi, Try converting your form to a UserControl. It works better. Do your best to be the best Re: Setting a form onto a panel. JacquesDP12-Oct-06 21:38 JacquesDP 12-Oct-06 21:38  Not sure if I did it the right way, tried it via casting. ie Form form1 = new Form(); UserControl uctrl = new UserControl(); uctrl = (UserControl)form1; But compilation fialed and I recieve the error - Cannot Convert Form to UserControl He who laughs last is a bit on the slow side Re: Setting a form onto a panel. AB777112-Oct-06 21:52 AB7771 12-Oct-06 21:52  to convert the form to usercontrol just change the class derivation from Forms to UserControl. Thanks & Regards, Pramod "Everyone is a genius at least once a year" Re: Setting a form onto a panel. JacquesDP12-Oct-06 22:07 JacquesDP 12-Oct-06 22:07  Just to make sure I understand this correctly. You mean... I must change the folloeing within the form that I try to load into the panel?? public class frmReportPrintSettings : System.Windows.Forms.Form Change to public class frmReportPrintSettings : System.Windows.Forms.UserControl He who laughs last is a bit on the slow side Re: Setting a form onto a panel.

A simple way would be to try to instantiate the COM object you intend to use. If this throws a COMException, the component usually simply isn't registered (yet). But there is no way you can find out which folder a component has to be registered from, that completely depends on the component you want to use.

Re: how to find registry of com coponents vinay_inavolu12-Oct-06 20:29 vinay_inavolu 12-Oct-06 20:29  When client deploys the application and Com components are not registered it throws the exception. so that needs to checked and added as users wont have knowledge on registering the dlls. Re: how to find registry of com coponents mav.northwind13-Oct-06 0:48 mav.northwind 13-Oct-06 0:48  Yes, if the components are not registered correctly, the exception I've mentioned will occurr. But, as with all exceptions, you can catch them ("that needs to checked") and then register the dlls yourself (using Process.Start("regsvr32 -s comdll.dll");) if you know where they're located.

You're in the C# board not in the javascript board. To answer your question, you could simply use a change event where you can then check by using, for example a regular expression. how can i print the crystal report in landscape ayyp12-Oct-06 18:55 ayyp 12-Oct-06 18:55  hi all , i need to print my report in landscape when the user click on the print button(with out showing the preview dialog)...i tyr this with the following code but it still print in portraid... here is my code..
