Thanks for the input, Eddy. I guess it's a good idea to try and put it in a simple console app. It might be crucial that I'm jumping through separate vs projects etc, so I left it as-is. I'm not sure why CR5 has a main. It's mostly just a dll and not a form, unlike a lot of my other classes.
cr is an iCR type. It looks like this in the factory:
public iCR GetCR(CRType type, int slaveIndex)
{
iCR cr = null;
switch (type)
{
case CRType.CR5:
cr = new CR5_new.CR5(slaveIndex);
break;
case CRType.CR6:
cr = new CR6.CR6(slaveIndex);
break;
default:
throw new ArgumentException(string.Format("A CR of type {0} cannot be found", Enum.GetName(typeof(CRType), type)));
}
return cr;
}

Good start. The Cr5_Comm class is missing from that. Good idea for ProgressChangeHandler to lose the 2. If you don't have the iCR_Comm interface, it's like I never made my changes at all.

Can CR5 inherit from both iCR and iCRComm?
|
|
|
|
|
Your definition and use of iCRComm is what my iCR interface is. It's still not doing what my iCRComm does. Thanks for helping!!
|
|
|
|
|
Yes; although I don't see why one wouldn't simply modify the original interface to include the new method. Remember that the factory is there for a good reason.

Yes, but I have two factories. One for CR5 interface and one for CRComm interface. It may not be obvious from what I posted, but they have very different uses. Generic needs to use CR5 for writes. CR5Comm is used all over the place and definitely isn't the same/can't be condensed into one with CR5. You're changing the use of everything too much for it to be helpful. Maybe we need to go back to the original VS project definitions of everything? I know it's difficult, but it's like that for a reason. Even where you put the delegate doesn't translate to anywhere in my code.

I'd expect anything out that factory to behave similar; otherwise you'd be checking whether you're working on a CR5 or a CR6 everywhere in code, making things even more complicated.

As far as the compiler is concerned, it's located in "some" namespace. As long as it's referenced, it can be used.

Like I said. There are two different factories. One for comm, one for crx. I get two different things from them. The fact that I don't have a check for CR5 or CR6, is because my cr factory returns an instance of iCR that is an instance of either cr5 or cr6. When I make a call from my instance of icr that is returned, it will automatically go to the implementation of cr5 or cr6, whichever I instantiated in the factory.
I realize the compiler doesn't care about the delegate location and usage, but I do. The structure/fix that you are suggesting doesn't translate even slightly to my code, which is in separate vs projects. I can't put my delegate where you have it, so it's not a fix for my problem. Thanks for the help!

Aight, can you add in the project names in the original post? Make 'em fake ones if required

Thanks! I updated the original post with vs project names.

I did, but I won't be able to work on it until I am home

Guess what???! I cleaned all of my classes, detached and re-attached references, and it's working now. I guess I had the delegates/events and the interfaces set up correctly after all!!!! I was stepping through and noticed an exception was being thrown so I wasn't getting to my event setup (+/-), so that's why it was null and missing updating the progressBar. Thanks for the help!!

It seems like the place you're putting the delegate won't work for me since you have it all in one program and I don't. I see that it works, though.

How to view the images from folder one by one by clicking next and previous button in c#
|
|
|
|
|
Exactly how you do it depends on teh environment, which you don't specify. For a web based solution it would be different from a WinForms version.
Winforms is easy (but even then there are a number of ways to do it):
Read the list of image files (using Directory.GetAllFiles)
Set a class level index to 0.
Show the first image, by loading it (using Image.FromFile) into the Image property of a PictureBox.
When the next button is pressed, increment the index, and show that one. Similar for the previous button.

foreach (var image in images)
{

code is simple:
System.Diagnostics.Process.Start("sc", "\\\\" + strMachine + " config \"<the service name>\" start= demand");
not getting any exception or anything. My code is impersonating a domain user that has admin rights on that box. I know the impersonation code is working because I use it elsewhere.
Also, if I do a runas command prompt and run the command line manually, it successfully works, so I know the username and password are correct. Just can't do it from C#.
I can't see if its spitting out any errors as the dos box flashes too fast.
Any ideas?

Don't build the command line argument string inside the Start method. Build it into a variable so you can see EXACTLY what is being sent to the Start method.
|
|
|
|

Yeah, I've done that and its EXACTLY what I ran under the runas command. I've tried both the code I posted (while impersonating the domain account that has admin rights) as well as the version of Start where you pass in the username, password & domain. In addition, as proof that my impersonation code is working, I'm able to start & stop the service remotely with the service control manager class. I'm also able to execute pskill remotely (to kill a process).

Seriously?? "<the service name>"?? That's not exactly what you're running at the command line...
If you're getting the black CMD window to show up and then disappear, it means that you're:
1) Launching the command as a user that doesn't have permissions to execute the SC command on the target machine.
2) The service name isn't correct.
3) Something else in the command line isn't correct.
To check to see who the command line is running as, change the Start call to launch .Start("CMD", "/K WHOAMI")
After you've verified who the command is running as, you can alter your command line to launch the SC command and have to command prompt stick around: .Start("CMD", "/K <your entire SC command line here>")
Oh, remember what I said about building the command line in a seperate variable?? This is where is comes in handy...
