Oh, it's a WPF application? Sorry, I assumed it was a WinForms application. My WPF knowledge is a bit rusty, so I'm not sure how much help I can provide.

Have a look at this code that was auto-generated when I added an event to a control:
((System.Windows.Controls.MenuItem)(target)).MouseDown += new System.Windows.Input.MouseButtonEventHandler(this.MenuItem_MouseDown_1);

Notice that the namespace of the event handler is not the same as that of a WinForms event. This also means that the controls does not always support the same events as their WinForms equivalents (such as having a MouseDown event but not a Click event). Make sure what events your control supports and where the event handler delegates are.

With that in mind, your code would then be something along the lines of:
viewAllStaff.MouseDown += new System.Windows.Input.MouseButtonEventHandler(pdt.viewAllStaffMethod);
and
public void viewAllStaffMethod(object sender, MouseButtonEventArgs e)
{
// Your code.
}

In that case, I'm not sure what went wrong.

Have you tried adding an event handler through Visual Studio's GUI builder? Just select the menu item you want to add an event to, go to the Events tab of the Properties pane and double-click on the Click event.

I've updated my answer.

For future reference: If you want to respond to an answer, add a comment to that specific answer (there is a button underneath it labeled "Have a Question or Comment?"). That way it is clear that you are responding to that specific answer, the user who answered is notified that there is a comment, and other people reading the question are not confused when they see an answer that asks a question instead of providing an answer.

So you want to display the document without saving it to disk? I think your best bet would be to save the document to a temporary file.

Nobody can give you specific help if you don't show us the code, but here are some links that might help you solve the problem yourself:

Hope that helps.

That's the most confusing sentence I've seen all day.

Forum rather than QA, because it would be better to have a conversation about these questions with a back-and-forth about what the OP understand and don't understand.

Design & Architecture because, well, that's the only one I could find in which it would not be completely off topic.

This kind of question would probably be better in the Design & Architecture forum, because it makes it easier to have a conversation about the topic.

While it's nice to see the XML you want to read, it would be even better to see the code that reads it. Could you please post that?

Two hints:
1. When catching an exception, return "ex.ToString()" rather than "ex.Message". ToString has the message along with some other info, such as a stack trace. This can be very useful in figuring out where exactly the problem is.
2. Place a breakpoint in Visual Studio and step through the code. See where it breaks. Inspect the values of variables to ensure that they have the values you expect them to have (you can mouseover a variable or property to see its value).

When you know more, edit your question to include the extra details (such as on what line the exception is thrown). While you're editing your question, also please place the code in a code block - that makes it much easier to read.

No. I have very limited knowledge on biometrics myself, so I doubt I'll be able to help you.

But if you want others to help you, you need to provide a bit more details about what exactly you are having difficulties with.

Did you receive any documentation when you bought the fingerprint reader? Is the documentation not sufficient to get you started with your code?

What have you tried? What model from which manufacturer are you using? What does the documentation say?

Have you looked at the API yet?
http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#isAlive%28%29

What's the question?

Word of advice: Code are much more readable if it is inside a code block. It would have been better to update your question to include the code.

If you didn't get answers yesterday, you are not likely to get answers today if you repeat the question without adding any more details. What have you learned since yesterday? Do you think it might be time for you to log a bug with Microsoft?

Before re-inventing the wheel, have you had a look at what's already available?
https://www.google.com/search?q=remote+desktop+android[^]

Word of advice: tag this as a VB question.

You already asked this question, got two answers and accepted one of them as correct. Why on earth are you asking the question again?

Probably a different drive than the one running the OS and application. I hope.

The linked page contains more than one way. If none of that helps you, try to explain what exactly the problem is and why the approaches you can find with a simple Google search doesn't work for you.

What have you tried?

Homework questions are frowned upon here.

Have you tried Google?[^]

If you want any help here, you need to start by doing three things:
1. Place your code inside a code block.
2. Post only the code necessary for the question - no more and no less.
3. Ask a question. We cannot look at your code and guess what you want to know.

I'm not sure I understand what you mean. What line are you not getting? Is it this line: xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema";

If so, try adding the following lines to your code (after doc.AppendChild(rootnode);): doc.DocumentElement.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");
doc.DocumentElement.SetAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");


If this is not what you mean, please explain what the problem is.

I don't think I can make it any clearer than the error message you posted makes it:

"You can grant ASP.NET access to a file by right-clicking on the file in Explorer, Properties and select the Security tab. Click Add to select the user or group to add. Highlight the ASP.NET account, and check the boxes for the desired access."

You can use the same method to copy files over a LAN. See http://www.vbdotnetforums.com/vb-net-general-discussion/22592-copy-files-over-lan.html

OK, I looked up how to access the control in the code-behind. It's as easy as specifying a Name in the XAML. Can't believe I forgot that :-) Updated solution.

Sidenote: Pete O'Hanlon's approach is a much better one, so once you feel comfortable enough with WPF, I suggest you try that instead.

Yes, you can name it whatever you want to.

I don't understand your comment. Can you please rephrase it?

Great! Go ahead and do that then. If you get stuck, you're welcome to ask a specific question.

Not much we can do without seeing some code, but index -1 means nothing is selected. Hope that helps you figure it out.

This question is too open ended for the Q&A section. Try starting a discussion in one of the forums, such as the Lounge[^], Design and Architecture[^], or even Visual Basic[^].

This question looks incomplete. Maybe you should try using the "Improve Question" widget to make your question more understandable.

Which part are you having difficulty with, figuring out which controls to delete or deleting the controls?

What have you tried?

Can't imagine that we do. I also find it hard to believe that it would be required in the USA. Could you perhaps provide a link to the site in question?

I'm about to pack up and go home, so don't expect another post from me over the next few hours. That said, here's my next suggestion: Debug and step through your code. Look at the values of the variables after each line has executed.

If you don't know how to debug, have a look at this tutorial (or search the web for a different one if you prefer): http://csharp.net-tutorials.com/debugging/introduction/#.UKOqsmf2phE

Don't put AppGlobals it in two files. That means you create two classes, one being used by Form1 and one being used by SolidWorksMacro. Instead, try to create a different file for the new class:
1. Go to Solution Explorer in Visual Studio (you are using Visual Studio, right?).
2. Right-click on you project (probably the second item you'll see, the first one is the solution (which is basically a collection of projects)).
3. Select Add -> Class
4. You will probably be shown some sort of dialog box where you can specify the name of the class (may be different based on the version of Visual Studio you have). Give the class a suitable name and continue.
5. Once the class is added, you should see a file with some skeleton code for you, such as:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Example.csproj
{
class AppGlobals
{
}
}

6. Add the line "public static bool IsFormFinished = false;" between the inner braces.

I've made the code more copy/paste friendly. What specific errors are you getting?

Yes. That's why I invoke the method on the UI thread.

Not true. As soon as I try executing the delegate without invoking it on the appropriate control, I get an InvalidOperationException telling me the cross-thread operation is not valid because the control can only be accessed from the thread it was created on.

It is done for thread safety. It is basically a way to force the method to be executed on the GUI thread.

This works fine, up to the point of invoking the delegate. Unfortunately, Invoke now returns null.

That's quite a nice idea. Thank you!

Hmm, looks like I'll just have to be satisfied with registering the assembly. Thanks for the info.

BTW, I didn't mention what the host app is because I didn't (and still don't) think that it's important. Rest assured that it is not Office, or anything similarly common (If it was, I would've mentioned it).

I also would've preferred a pure .NET approach, but unfortunately that does not seem to be an option here.

This does not discount the possibility of a threading issue. If your system is more powerful than the client's system, then the code that gets executed on the UI thread might happen so fast that you don't notice the delay; but on the client's system it takes just long enough that it is noticeable from time to time.

When the application freezes, how long does it freeze before continuing? Does the client force quit it while it freezes? Is there any other patterns that you can see as to when it freezes and when it works perfectly?

Don't ask me, I'm just the coding monkey that gets to fix stuff ;-)

To be honest, I'm not sure. The application was created by an external vendor before I joined the team I'm in now, so I know very little about the reasoning behind it. However, would VB.NET be able to run within a host application like VBA can?

Yet you expect us to do your work for you?

If you want us to help you, you'll have to show us that you tried to help yourself first. Show us what you've done so far. "i tried.. but it still goes wrong.." just won't cut it. It's far to vague. Have you read through the requirements? Did you fully understand what you are supposed to do? Have you started coding? What have you coded so far? What exceptions are you getting? What program behaviour differs from what you expected?

From what you've said so far, I suspect you have done just about nothing yet. If that's the case, you will be hard-pressed to find someone willing to spoonfeed you here. Even if you do, you will have to provide more details. How does your database look? What is the hardware and software that you can build your app around? What do you mean by "point of sales"? (i.e. do you want to do any random thing that one might reasonably expect to happen at a tillpoint, or do you have something more specific in mind, such as reading a credit card and kicking off a transaction to the acquiring bank?)

I really hope I got the wrong impression from your question, because there's already enough stupid and lazy people around, we don't need any more.
