Modify a form's control properties from a class

Hello,

If I have a class that does some calculations and I want to show the result of those calculations on a form's textbox, how can I do that ?

I have tried writing the following on the class, but it doesn't work:

form1.textbox1.text = showData(initialValues);

Where show data is one of the class' methods and it returns a string.

form1 also shows some other data that doesn't have anything to do with the method showData. showData is invoked by pressing a button on form1.

Thanks.

Regards,

Carlos

Carlos,

Do you have your capitalization correct? Perhaps it should read:

form1.textBox1.Text = showData( initialValues );?

How to merge two datasets?

Lexa198311-Dec-05 8:28

There is table with name TableName in first dataset
Id Name Selected
----------------------
1000 Name1 0
1001 Name2 0
1002 Name3 0

There is table with the same name in second dataset
Id Name Selected
----------------------
1000 Name1 1

How can I merge them to get this:
Id Name Selected
----------------------
1000 Name1 1
1001 Name2 0
1002 Name3 0

I prefer to do this by using Merge method, but not with foreach...

Where do you get the datasets from? If you fetch them from a database, you can easily merge them in the query. Example:

select Id, Name, Selected from Table1
union
select Id, Name, Selected from Table2
order by Id

---
b { font-weight: normal; }

Merge will only merge tables into the dataset not the actual table.

Calling ImportRow on the target table will do what you want.

You much better off to put this action into a stored procedure get the result into a table.

Your trying to do a set method in an ISAM structure. It wont work.

I'm not an expert yet, but I play one at work. Yeah and here too.

Use Microsoft.mshtml.dll, you can retrieve the DOM tree as mshtml.IHTMLDocument2

Optionally, if you're using .NET 2.0, you can use the System.Windows.Forms.WebBrowser to load an HTML document, then return the DOM tree using System.Windows.Forms.WebBrowser.Document.

To open a new window, using form.ShowDialog()

You can create a Form[] and add eached launched form to that array, sure. Or, use System.Collections.Generic.List<Form> if you want the list to grow as necessary.

If I'm not understanding your problem, you'll need to write your English clearer, as it is difficult to understand.

Which System.License library are you speaking of? AFAIK, there is no such library in the .NET framework class library.

There's no License class in the System namespace. There is in the System.ComponentModel namespace, but this is used for DesignTime and Runtime licensing of controls used on forms, not for licensing an entire application.

There is no standard for this. There is no standard form of a license key. This is done using 3rd party libraries or your own concoction. No, I don't have any examples. Your best bet is to Google for something like "license software developer"[^], and start doing a bunch of research to find out what's going to meet your needs.

Reading Foxpro dbf files

Hi,
I'm not much familiar with Foxpro files. I'm just about to read a bunch of dbf files. The problem is that I can open some of them in visual studio.net, but when trying to open the rest, I encounter the following error:

External table is not in the expected format. (Error 3274)
The format of the table has changed since it was linked. Link the table again, and then retry the operation.

I can't even open those *.mdf files in the Microsoft Access because of the same error that occures. Do you know why it is like this, and how I can solve it?

Thanks in advance

u can to to connect to indivudual table instead of database.. use use the foxpro table driver in ODBC there..

Is there a possible way to user print merge in C#? This is my problem we are having some network issues and our jobs are not running properly, the hang up is from our parent company. This is causing headaches for me because the SQL job doesnt run hence no data to merge.

I know how to call the data I need and mold it. I need a way to be able to print merge everything in this possible dataset.

Any ideas??

Thanks
