Re: debugging managed code and native code together George_George18-Jan-09 1:58 George_George 18-Jan-09 1:58  Thanks Abhijit, The document about debugging you recommended is for smart device. But I am debugging on Windows Server 2003 x64 platform. Any other comments or ideas about how to debug? BTW: The article you wrote looks cool! Great!! I have a related question, what is the differences between we assign keep-alive and not keep-alive in HTTP connection to a server? regards, George Re: debugging managed code and native code together Alan Balkany19-Jan-09 3:52 Alan Balkany 19-Jan-09 3:52  Here's a neat debugging trick I learned a while back for debugging a component that's different than the component that starts execution. (I'm not sure if it applies to your situation. It might.) 1. Open the component's project in Visual Studio. 2. Double click Properties in Solution Explorer. 3. Click the Debug tab. 4. Under Start Action, click Start external program. 5. Enter the path to the executable that starts execution (and later calls the component you're trying to debug.) 6. Press F5 to start debugging. This lets you set breakpoints in the component you're trying to debug. Hope it helps. Re: debugging managed code and native code together George_George19-Jan-09 19:14 George_George 19-Jan-09 19:14  Thanks Alan, Your solution works! Cool! 1. A further question, I find if I build my hosting .Net console application as Mixed Platforms, I can not debug COM x64 it used by using the method you mentioned. But if I build my hosting .Net console application as x64, I can debug COM x64 by using the method you mentioned. So, what is the differences between Mixed Platforms and x64? 2. Any ideas why Mixed Platforms build does not work but x64 build works? regards, George Re: debugging managed code and native code together Alan Balkany20-Jan-09 3:29 Alan Balkany 20-Jan-09 3:29  I haven't worked with Mixed Platforms or x64 yet. Try asking at stackoverflow.com; the response time is pretty good over there.

Karmendra Suthar17-Jan-09 21:50 Karmendra Suthar 17-Jan-09 21:50  Hi, I have help files written in HTML, which I display in my Win Form application using Web Browser component. But now I need to make sure that these files should be accessed only by my application, user should not be able to access these files from the location where these files are installed. Thanks, Karmendra Re: Prevent un-authorised access to files. «_Superman_»17-Jan-09 21:58 «_Superman_» 17-Jan-09 21:58  Keep the help files encrypted and decrypt them before displaying them from your application. «_Superman_» Re: Prevent un-authorised access to files. Karmendra Suthar17-Jan-09 22:17 Karmendra Suthar 17-Jan-09 22:17  Hi, I thought of the same thing, but I was wondering how to do it, can you tell me how can I encrypt ant keep the html files and then how can I decrypt it in the application. Thanks, Karmendra Re: Prevent un-authorised access to files. Wendelius17-Jan-09 22:01 Wendelius 17-Jan-09 22:01  If you protect the files so that they are not accessible by the user, then they wouldn't be accessible by your application which the user runs. Possibly one way could be that you embed the help files to your application. In that case you don't have a separate help file at all. However, then you should extract the help and store it somewhere when you want to show it. The need to optimize rises from a bad design.My articles[^] Re: Prevent un-authorised access to files. Karmendra Suthar17-Jan-09 22:37 Karmendra Suthar 17-Jan-09 22:37  Hi, I meant users should not access the files directly in the installation folder and open and view it using there internet browser. The only way for them to access those files is via my application. As you suggest embedding it, can you tell me how that can be done, sorry This might be silly to ask but I am very new to .NET and C# Thanks for you help and time Regards, Karmendra Re: Prevent un-authorised access to files. Wendelius17-Jan-09 22:50 Wendelius 17-Jan-09 22:50  I think that the problem is that your web browser shows the document based on URL. So in my understanding you must point the url to a valid location where the html is located. Now where ever you store the html, I think it needs to be in a file, in clear format the moment the browser accesses it. If you embed it, you could write a temporary file and get the contents using GetFile method in Assembly class. After the help is closed, you would remove the remporarty file. The file itself is included in the project using Add Existing item in Project Explorer. The need to optimize rises from a bad design.My articles[^] Re: Prevent un-authorised access to files. WritinCode18-Jan-09 0:06 WritinCode 18-Jan-09 0:06  Encrypting the files individually would probably be less intrusive if you needed to update a single help file whereas there is no change to the application. You could embedd them but that would mean any change to the help file requires a new binary. From a support perspective, keep them seperate. Schott Re: Prevent un-authorised access to files. DaveyM6918-Jan-09 1:20 DaveyM69 18-Jan-09 1:20  A combination of the suggestions above - why not create a seperate assembly that creates the html in memory or has them embedded - and use that to serve the html source to your main app. An update to the help would just require that dll to be redistributed. Dave BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn) Visual Basic is not used by normal people so we're not covering it here.

Re: Prevent un-authorised access to files. [modified] Luc Pattyn18-Jan-09 22:10 Luc Pattyn 18-Jan-09 22:10  Hi, you could add an "enter password" dialog to the HTML code, have most of the page content encrypted and include some JavaScript that checks the password and decrypts the text. Don't ask me for details though, I'm not inclined to do such things myself. I'd rather create my own file type and non-HTML browser.

Re: providing sql database with you're application install for customer side Wendelius17-Jan-09 21:55 Wendelius 17-Jan-09 21:55  The only configuration when you don't need to install SQL Server is when you use compact edition, which is intended for local single-user systems as a small database. If you use Express edition or higher, SQL Server installation is needed. The need to optimize rises from a bad design.My articles[^] Re: providing sql database with you're application install for customer side spiritboy17-Jan-09 22:07 spiritboy 17-Jan-09 22:07  i have used enterprise edition, you mean that i have to seperately install sqlserver and then install my app? Re: providing sql database with you're application install for customer side Wendelius17-Jan-09 22:16 Wendelius 17-Jan-09 22:16  Well, if you use Enterprise Edition, the first thing is that it's licensed pruduct and the customer must purchase the license in order to use that edition. When the licensing part is managed, then you would install the SQL Server (or the customer installs it beforehand) and after that in a separate installation you would install your application. I'm not sure if there's a way to link these installations, but the most important point is that you cannot distribute Enterprise Edition with your application without the customer having a valid license. The need to optimize rises from a bad design.My articles[^] Re: providing sql database with you're application install for customer side WritinCode18-Jan-09 0:14 WritinCode 18-Jan-09 0:14  No you shouldn't include the SQL Server install as part of your install. Usually when SQL Server comes into play it is installed and configured as a seperate task. As mentioned before, a license would need to be purchased to use the product on the up and up. The sequence in which you install your application doesnt not matter, you will just need to know the specifics of the SQL Server and your application would then be able to connect. In the past I've just had a SQL Svr property page in which you define the svr name, logon parameters, database name and port. Schott How do I draw the image of a 'System.Windows.Form.Control' instance onto another Form astibich217-Jan-09 15:15 astibich2 17-Jan-09 15:15  I'm writing an editor Form that operates on any instance of a 'Control' class. I'd like to show an image of the active control context in the upper left of my Form - just so the user gets a visual of what control they are working on. Is there a way to get a Control to draw onto a Form that is not its parent? I've been play around with Control.DrawToBitmap, but I can't seem to make it work Thanks, Aaron
