I want to have an input from the user to define the font of a rich text box... the only problem is the only way I know how is to use a string... When I use a string it give the error of:
"An unhandled exception of type 'System.InvalidCastException' occurred in PWT Notepadd.exe
Additional information: Unable to cast object of type 'System.String' to type 'System.Drawing.Font'."
TextBox1.font.size = "8".Gives me an error.... what would be the proper syntax to define a font size in code.yes I know it can be changed in the properties but I need to know to change it in code too..

I parse time from string. The time in string is always GMT (you may say it equals UTC).Now I need to convert this time to local time, but there is a catch!For some reason the time parsed from string is being assumed as local time. I need to tell the bloody machine that this time is UTC/GMT, but not local.
Some examples:My string looks like that:
06 Apr 2012 16:27:00 GMT
I parse it like that (eventtime is my string - like above):
vb
Dim eventtimeobject As DateTime = DateTime.Parse(eventtime)
Dim eventtimefriendly As String
eventtimefriendly = String.Format("{0:dd MMM yyyy HH:mm}" + " GMT", eventtimeobject)
and now if I would like to convert it to local time nothing will happen as it is assumed that the above time is actually local.obviously if I tell it to convert the above time to UTC/GMT it will change it, as it does not know what this time is in GMT already.How do I do it? How to I tell the computer that it is dealing with GMT already?
I'm programming in VB.NET using Visual Studio 2008. I need to define a string literal containing the character "÷" equivalent to Chr(247). I understand that internally VS uses UTF-16 encoding, but when the source file is written to disk it contains the single byte value F7 for this character.
This source file is processed by another program that uses UTF-8 encoding by default, so it fails to interpret this character correctly, attempting to combine it with the following single-byte character. What encoding would correctly interpret the single byte F7 as the single character ÷?
Alternatively, is there a way of expressing a non-ASCII literal that uses only ASCII characters - like using some kind of escape sequence?
I would like to develop a Windows Service in VB.NET to monitor different SQL databases running in different servers. The user will enter/define connection string for each database.Also he/she will define connection interval.
For example, database A needs to be checked in every 5 mins and database B needs to be checked every 24 hours.
What is the best approach for this project?

I'm saving the font of a label to a text file, and when I open the text file with my program, I want the label to have the same font that is listed within the text file. Now, the only problem I am having is that when I try to write the code for opening the text file, I can't set the font property of the label to a string. Label1.Font=[Font: Name=Microsoft Sans Serif, Size=9.75, Units=3, GdiCharSet=0, GdiVerticalFont= False]Here is what the code to open the text file and set the font of the label looks like:[code]The problem for the code happens at line 6. The error is: "Value of type 'String' cannot be converted to 'System.Drawing.Font'"ing each part of the font in the text file(i.e. Writing Font.Name and Font.Size properties in separate lines and then setting the label's font properties to each line accordingly), but I still get hit with the same error.

So I set the "enabled" property of the textbox to "false"(because I want it to display, not receive input) and then choose the background colour to be white. In the form designer, the text colour is black, which is what I want.But when I start debugging, the text becomes the colour of the form. How can I make the font black?
