How would i set a minimum number of characters in textbox1 for a button to work. and if the person does not enter the minimum number of characters, a messagebox pops up sayin something like "need at least 5 characters!"
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.
Function GetNextAvailableNumber(NumofDigits) as Long 'SQL Code Here ---- 'Query Number Table
How do I write an expression to calculate all characters of each row by my own defined value to each character = all the A and B and C and etc. will be as 2 and all I and J and whatever ... will be 1 so I need an end result of the total.
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.
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.
I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
I'm attempting to invoke with parameters:[code]Value of '415' is not valid for 'Value'. 'Value' should be between 'minimum' and 'maximum'.Parameter name: Value..What does this mean? Is there a way around it?
I need to use a trackbar as a scrollbar, but the problem is that the min value is at the bottom i need it to be 0 at the top and maxvalue at the bottom..

I want to read a text file(.txt) character by character into a database.There are 28 characters on each line and I want to read the first 16 into a column in a database and the rest in another column in the database.
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.
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.
I got a progressbar in my game (Hpbar) and a lots of time the value go under the Minimum Value and it crash... Any way to make it go back to minimum value 0
I was unable to get these instructions to work:When pasting in the code below, I get an message that says "Statement is not valid in a namespace".I am using .NET 3.5 for my program, and the code came from:aspx

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:
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?
SqlServer Table1 has data as follows Sno-------date 1------01/01/2010 8------01/01/2010 1------02/01/2010 5------02/01/2010 2------18/01/2010 9------18/01/2010 3------18/01/2010 1------03/01/2010 6------03/01/2010
My questions are: 1) I want to display the SMALLEST Date into textbox1 which is 01/01/2010 2) I want to display the BIGGEST Date into textbox2 which is 18/01/2010 3) I want to display the BIGGEST SNO against date 18/01/2010 into textbox3 which is 9 4) I want to display total records against date 18/01/2010 into textbox4 which is 3
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've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code: ABinary = "0110 1100 0001 1011" For x = 0 To Len(ABinary) - 1
i am having a problem in building up a VBcode for getting the minimum distance between a set of coordinate points. what actually i an trying is to find the minimum distance between one set of coordinate points(A(x1,y1),Bx2,y2),C(x3,y3),D(x4,y4),E(x5,y5)) with respect to another set of CO-ord points (i(x1,y1),j(x2,y2),k(x3,y3),l(x4,y4),m(x5,y5))..

[code]....
the above is code which i have created till now and the next step is calculating the mindistance criteria..search criteria . rear points is the one we get frm solidworks and b.rearpoints is the one present in database we compare both of them find the one which is very similar to the one in database..
I'm trying to check whether values ar between a maximum and a minimum limit. I do that 21 times, and it works 20 times. In case of the 21. time VB tells me that 15 is less than 8. Here the relevant lines of
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
