so I created a new control. When the user changes the font, I don't want the user to change the font past font size 14. If the user changes the font past 14, the font should reset to 14.Here is what I have so far.

Dim myFont As Font

The problem here is that this code makes the font, Arial 12 static, and whenever I change the font size, the font always goes back to Arial 12.

View 2 RepliesWhat is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).
View 5 RepliesI've had a look around, once again and can't find how to set the minimum and maximum dates allowed to be selected on a calendar in ASP.net with VB.
I'm using Visual Studio 2010 and it's just a regular Calendar control at the moment...
At the moment I've seen things like:
Calendar1.DateMin = DateTime.Now
But Visual Basic doesn't seem to like that (maybe it's a C# thing?).
I have a list box on my form with 2 value - "2010" & "2011". When I change the value in the listbox it should set the minimum and maximum value of 2 datetimepickers. Each time I try to change the value I get an error - for example if I change the listbox from 2011 to 2010 I get the error:
"Value of '31/03/2011 00:00:00' is not valid for 'MaxDate'. 'MaxDate' must be greater than or equal to MinDate. Parameter name: MaxDate"
If ListBox1.SelectedIndex = "0" Then
DateTimePicker1.MaxDate = #3/31/2011#
DateTimePicker1.MinDate = #4/1/2010#
DateTimePicker2.MaxDate = #3/31/2011#
DateTimePicker2.MinDate = #4/1/2010#
End If
If ListBox1.SelectedIndex = "1" Then
DateTimePicker1.MaxDate = #3/31/2012#
DateTimePicker1.MinDate = #4/1/2011#
DateTimePicker2.MaxDate = #3/31/2012#
DateTimePicker2.MinDate = #4/1/2011#
End If

View 3 RepliesWhat is the point of the max value of a scrollbar when it can't be attained? I put a horizontal scroll bar on a form and set the maximum value dynamically. After a bit of testing, there is no way for the scroll bar to attain this maximum value. Instead, I am always ending at Max-2. It always comes up two short. So what is the point of the maximum value if it can't be attained?

How can a TextBox or RichTextBox buffer size be set? I have data that goes to a TextBox continuously, but I want to set a maximum size of buffer for the TextBox. I read in one forum someone suggesting to set the TextBox MaxLength property, but the questioner replied that he had tried this, and when the MaxLength was reached no further data input was possible, and what he wanted was the situation where new data could still come in, but the oldest data was then deleted, i.e a rolling buffer, which is precisely
View 3 RepliesI built a console application that reads a directory of files, builds a 'put' statement for each file and submits each statement to a webservice. Then, it reads the webservice output (for each statement), parses it for a specific string, builds a 'get'statement and submits the 'get' to the webservice (for each file).Then, the application reads the 'get' output stream and writes a file (to the local file system) for each file that was submitted, using a streamwriter.I have encountered an issue where some files are unable to be written to the local file system by the streamwriter.After much testing I have figured out that any file exceeding 4096 bytes will cause the application to hang where streamwriter should write the output to file.I have tried the syntax below to increase the size of the streamwriter buffer however, it doesn't seem to be working.I do need to mention that I am an extreme novice with VB or any other language and have, for the most part written this module from research and code samples.I should mention that this module does work for any file that is less than 4096 bytes in size.

I am working on an application using vb 2008 express. I have built test programs over the past few weeks and shared them for feed back. Today when I finished some work, I built another test application, but when I install it the start-up screen maximizes but is set between one and two desktop icons from the top of the screen.
In debug mode it looks fine. In the past it looks fine. Each time I start the program the screen is in a slightly different location. It is set to start maximized and to the best of my knowledge, I did not change any settings in the property area. I have tried loading on three computers and the results are the same. Any ideas on what I could have done to produce this strange result?
