Hi Paul,

Almost all on the list are about how to use OLE DB provider (as an OLE DB consumer), but what I am looking for is how to implement OLE DB provider, here is the related sample in C++,

http://msdn2.microsoft.com/en-us/library/ms715011.aspx

I am looking for a C# sample.

regards,
George

I must have misread your original post earlier. From a quick glance of msdn link, porting from C++ to C# shouldn't be that difficult.

Hi Paul,

Do you know whether there are any tools to convert source codes from C++ to C#? The sample has almost 2k lines of code.

I don't really know of any tools for converting from C++ to C#. How much C# do you know? Are you learning it?

You can't check if a has any files in it without trying to read it. If your file system reports the a drive, that's what will happen. However, it is possible to work out what is a USB drive, what's a floppy, a CD drive, or a hard drive. DriveInfo[] allDrives = DriveInfo.GetDrives (); Now if you iterate over those objects, each represents a drive, and what type of drive it is.

CreateProcessWithTokenW

Can someone publish C# code to make use of CreateProcessWithTokenW function, so that i can run process just by getting token from current user, instead of passing user/pw for every run (WindowsIdentity.GetCurrent().Token)

Basically trying to extend impersonation functionality to disconnected functions like Process.Start()

Impersonation example:

Many thanks.

You may want to use CreateProcessAsUser instead. This[^] link shows how to do it.

Thanks Pete, I need to use CreateProcessWithTokenW as to allow seemless impersonation; without having to manage credentials.

I found an interesting site, but that also does not have a sample code for me...http://www.pinvoke.net/[^]

I need help,
Like we set breakpoint in .net,

we can set condition and hit count of that breakpoint in Breakpoint window,
now I want to know how to set this condition?

Suppose there is variable x,
i want to set like if x=5,
then only it breaks or breakpoint hit,

can we do like this!!!!

plz explain in detail!!!!!

I tried on my own many times but either breakpoint does not hit, or it says condition is invalid!!!!!

I want to set a condition for variable in C#.net

hi frnd,

statement x=5 ...........set the value of x to 5.
it does not check whether x is equal to 5 or not.

You have to use conditional operator(==) instead of assignment(=) operator.

So use x==5 as a condition.

Ok. Smile | :)

hi all,
how to make a setup file in such a way that prerequisites are installed automatically before application is installed, e.g. if .net framework 2.0 is not in target machine it should check and installs it before installing the application.

thanks,

You could go and have a look at Windows Installer XML. WIX for short. It should cover all your needs for checking registry prerequisites and installing your application.

I wrote an article on setup projects:
http://www.codeproject.com/dotnet/Win_App_Setup_Project.asp[^]

It seems that with vs 2005 the setup is improved to beable to check and install the .net framework. It checks the dependance prompts the user to accept the license. Then installs the .net framework. NOTE when it is done it is looking for the setup.msi file so that needs to be there.

Here is a microsoft link on it:

Is this a problem you're trying to fix or a feature you're trying to implement?

Sounds like it is something he is trying to implement. I would imagine just trapping the mouse click event and setting the Button property to the left button if this is possible...

Which I am not sure is possible since e.Button doesn't have a set property, only get...
