Hi,
I am writing a debugger and I am trying to implement a multi column TreeView for showing the local variabls (such as in visual .Net).
How can I implement it or maybe such implementation already exists as open source?

I've got an ASP.NET application written in C# which uses an Access database. Sometimes, when several users try to access the application at the same time, a "file is opened exclusively by another user" exception is thrown.
AFAIK, I need to synchronize access to the database. I've got a single place where all database access (like read a dataset, executenonquery) methods are. I tried using a ManualResetEvent to perform the task, but the problem is still there.
Can anyone recommend an approach?
Regards,
Serge

To handle multiple users, the Jet database engine has to be able to create a .ldb file (i.e. if your database is called MyDatabase.mdb, it has to create MyDatabase.ldb). Check that the user account your ASP.NET process runs under can create files in the same directory as the .mdb. If Windows 2000 or XP, by default it's ASPNET, while on Windows Server 2003 it's NETWORK SERVICE.
Stability. What an interesting concept. -- Chris Maunder

I've got the following problem: I have a DLL written in C++, that exports a function. That function basically puts a very simple CDialog object on the screen (either modal or unmodal).
I have a very simple forms-based C# program that uses this DLL to call the exported function. Everything works OK.
Now, I add a custom control in the CDIalog-derived class, in C++, using an OCX that was developed by another company. When having this OCX, the C# code calls the exported function, but the dialog is not shown.
If needed, I can provide the code.
Any ideas why I have this problem?

Please include a sample of the code. Also, have you tried to invoke this exported function from something like an MFC application?

I would highly recommend the documentation regarding ADO.NET located on MSDN. A good start is: Overview of ADO.NET[^] from the .NET Framework Developer's Guide. If you have further questions please feel free to post.

if I have two form, form main contain progress bar, form2 has a Cal() method. If I want to call Cal() that Cal method is activate progress bar. please show me a simple code. thank you
|
|
|
|

Who calls the Cal method; your main form or form2?
How are both forms related to each other? Is your main form the parent of form2/ has it a reference to form2?

Why would you call a function on a another form to start a control on your main form?
Are you asking how to increment the progress bar on Form1 from a function running on Form2?

that is to making a public property to the progress bar and calling parent.BarBrop.(the method u want);

I run into a NET application that looks simple but nice.
It had one color Test (vertical against the right side of the dialog box. When the mouse was over it, a sliding window slide (come out) to the right with additional choices to the user, When click DONE, it retracted.
Anybody knows how can I do that?
Any help will be greatly appreciated.

I don't know of any .NET Framework class either but you could simply call ExitWindowsEx()[^] (see also ExitWindowsEx() [pinvoke.net][^]).
Best regards
