I have 35.000 lines I want to add to a combobox, but this is too much... so I thought maybe there is a way to let the users type the first letter, and then show all the possibilities with that first letter. [URL]..Here I already found some information, but I can't get it to work.

View 6 RepliesI am not recieving any errors, but the program is not doing what I had expected. I wish to make a program that randomly takes characters (well, not completely randomly. I used the table of letter frequency from wikipedia and included that data in my program by figuring out the max for the random numbers from the percentages in the wikipedia chart.) and adds them to a long list of characters ands saves the file every 5 minutes. I have calculated the timer interval so that the number of miliseconds shown is equal to 5 minutes. I am getting the textwindow, and it is showing (rather rapidly, as I need it to be) a long random list of characters (including spaces). The problems are (A) I am having difficulty saving the text as a file. You'll find the code that is supposed to do that at the bottom. The other problem I am having is once so many characters are added, the ones at the top start disappearing. I would scroll to the top, and each time I did so the letters at the top had changed (this is all during the same test), but I need all characters to be stored when the file saves. Granted, I haven't actually seen one of the saved files as I have not figured out how to make that work. One other thing, not sure if it's important, I haven't run a published version yet. I've only been running the debug builds. Does that affect how it handles actions with files?

I am a complete beginner with Visual Basic, I am attempting to continue where the original creator left off. His project is finished but he didnt (and still doesnt) have time to fix a couple of bugs with his code....Basically, he has written a small VB application that closes SWF flash files if the CRC matches from a list... So when an SWF is loaded into explorer the SWF is hash checked and then closed if it matches from the "hashcheck.txt" file.
All is working apart from 2 small bugs:
1) %^&{}[]#`� - dont work.Ive found that If there is any of these charactors in the folder or filename structure the file doesnt get checked/closed.
2) Network paths do not work.. (maybe is part of above bug?)

I am investigating an issue with regards to a textbox rejecting user input. In this case the error message is: 'The note was found to contain a possible credit card PAN.'Now obviously this is a custom validator but I am enable to find where it tells me what characters ARE allowed? In debug I entered a note containing no numbers and when the validators are initialized, these variables have the value below:
valNoteContainsPAN.Expression = Me.PANRegEx value = (d*)45367{13,15}(?!d)
I'm assuming this is blocking numbers of certain lengths? How can I find out how to actually read and understand the above? Google is proving fruitless
I'm trying to put A Period After every 3 Characters In A Combobox. I want the user to be able to type an Ip ie:"255.255.255.255" and every 4th character automatically add a period .I already tried the formatstring no go.
View 3 RepliesI'm using comboboxes in my user form in Excel. I have two boxes, FromCombo and ToCombo, the first of which I have assigned values to using [Code] Now, my problem is getting the second combobox to work. I want it to drop down a range of values depending on what the user picks for the FromCombo. I have named the ranges List1, List2. Say the user chooses "KA 1&7" from the FromCombo, how do I populate the ToCombo with List 1? I thought it would be easy to use if statements and compare the value in the FromCombo so I use this Code: If FromCombo.Value = "KA 1&7" Then but its not comparing. So how do I compare the value in the FromCombo box?
View 4 RepliesI have a form created in VB.net. It is used to get some information form a user. The form is not bound to any data source.A combobox on this form is used to enter a cost. I want the value entered by the user to be displayed using currency format. I have used the Format String Dialog that opens from the ellipses button on the FormatString property of the combobox and selected Currency. This put C2 into the FormatString property.When I run my application, this format is not applied to the value entered into the combobox at the time the number is entered or when I leave the combobox.

View 7 RepliesI have a calculate function that adds twenty text boxes together a+b, etc... 20 +20, B changes value when a selection in combobx is changed, how can i make the calculate funtion work up selection change in combobox ? You would think the selection change or index change , but that doesnt work because the tetbox doesnt actually get the new value till after the combo selection is made, so you actually have to go and make the selection twice I know i can put the code in the textbox value change , but i dont want to do that for 20 text boxes and i am assuming there must be a BETTER way?

View 5 RepliesEssentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text

With the shape of really large characters such as numbers and alphabetic characters + others, is there a way to get that shape as a REGION please?Imagine a really fat snake forming the letter S or two rectangles placed together to form a large letter L or a T like the shapes in TETRIS.
1) Does anyone know of anything in VB.Net that can translate such shapes into a System. Drawing.Region or know of a project elsewhere that achieves this please?
2) While I'm on the subject, how would you SCALE UP / DOWN a System.Drawing.Region please? How would you work out the Transform Matrix required please?

Program works good, it is mixing characters good, but it doesn't write text to the file. It will write text in console, but not in file. Note: Program is working only with words that are divisible by 2, but it's not a problem. Also, it does not return any error message.
I'm making a custom control suited for handling passwords. I have created a control that inherits from a text box and I have implemented a lot of things so far. But what i want to do now is create a system so that when a user types It will display his last character typed for a X amount of time. Is there a way to turn only selected characters into password characters and still be able to get the password text from the Text property ?

I might create an "a bit "manual" function but before I prefer knowing if it exists something more automatic.

i am getting the above and i can not see where the '_1' are getting added. I don't want to mess too much with it incase it stops working the way i need it too. The lines in bold are the ones that write the results to a .tmp text, see below.

Why I get the Illegal Characters In Path error.
I'm trying to insert a - after ever 5 chars. I made this code.
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text.Length = "5" Then
TextBox1.Text += "-"
End If
[Code] .....
But the mouse returns always to the left after it enters a -.
So I have this
Dim a as string = "Hello"
Dim b as string()
now I want b(0) to have "H", b(1) "e", b(2) "l", and so on.
btw a changes everytime, so don't just say do b(0) = "H"
