SQL : Get Minimum Value From List Of 3, 4, 5 Digit Numbers But Want Minimum 4 Digit Number?

May 4, 2012

I'm using Visual Studio and table adapters using an Access DB as the backend. I need the minimum 4 digit value. I want to get next available 4 or 5 digit number. And this will change depending upon the users request. Currently I use a table adabpter query. But how would I write a query. I suppose I could do a long iterative loop through all values until I see a 4 digit.But I'm trying to think of something more efficient.

MemoryStream Truncating Input - Replace All Instances Of A Certain Character With A Unicode Character?

Jul 10, 2009

I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

VS 2008 Random - New Character Out Of The String And Then Remove The Character From The List Of Characters

Dec 12, 2010

[Code]...

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

Treat Unicode Character Plus Diacritic As A Single Character?

Aug 23, 2010

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.

NumericUpDown Defaulting To 'Minimum' Value

Oct 4, 2011

I'm using a NumericUpDown control with a Minimum set to 10 (using for font size setting). When it is changed, it is bound to an Application setting and saved. On Form Load, I am attempting to set the value of the NumericUpDown control to the value stored in that setting (14 for example). No matter what though, it doesn't use the setting's value, it uses the value of the "Minimum" property of the NumericUpDown control.

Printing With Minimum Margins Specified By The Printer?

Nov 1, 2009

I want to utilize the maximum paper area (A4 size sheet). Therefore I must get the minimum margins that specific printer can handle. I have more printers attached to th pc, so I can not hardcode these values. I have tried to set margins to zero, but that results in printing outside the page at right side and bottom:

PrintDocument1.DefaultPageSettings.Margins.Left = 0
PrintDocument1.DefaultPageSettings.Margins.Top = 0
PrintDocument1.DefaultPageSettings.Margins.Right = 0
PrintDocument1.DefaultPageSettings.Margins.Bottom = 0

So my question is: is it possible to read the selected printers minimum margins without have to open a PageSetupDialog, and therefore make it possible to utilize maximum printing area with code only?

VS 2010 - Vertical Trackbar (Minimum Value On Top)

Aug 29, 2011

I'm using a vertical trackbar. I got it all set: minimum and maximum values, tickfrequency etc... and so on... everything works great. The only problem is that I would like to have the minimum value of the trackbar on the top. In horizontal trackabar you can choose the RightToLeft property to put the minimum value to the left or to the right, but how do I make it to put the minimum value on the top if I have it in vertical orientation? There has to be a way to somehow "flip" it... but how?
Here is a link to video on youtube, which show my problem. I want it to be the other way round - from top to bottom: [URL]

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:

Forms :: DateTimePicker - Setting Minimum And Maximum Value

Dec 4, 2011

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
